LABIAL PAD HAVING A TAB
BACKGROUND
The present invention relates generally to absorbent articles such as labial
pads configured
for disposition within the vestibule of a female wearer. More particularly,
the present invention
relates to labial pads having at least one tab extending outward from the
periphery thereof.
A broad manner and wide variety of absorbent articles configured for the
absorption of
bodily exudates such as menstrual fluid are, of course, well known. With
respect to feminine
hygiene, the art has offered two basic types of feminine hygiene protection:
sanitary napkins,
developed for external wear about the pudendal region, and tampons, developed
for residence
within the vaginal cavity and interruption of menstrual flow therefrom. Hybrid
feminine hygiene
protection devices, attempting to merge the structural features of both within
a single type of
device, have also been proposed, but have not seen a meaningful measure of
acceptance insofar
as the effort to appropriate advantages has been overshadowed by the more
demonstrable
perpetuation of structural and anatomically functional disadvantages. Other
less intrusive
devices, known as labial or interlabial devices and characterized as having a
portion which at
least partially resides external of the wearer's vestibule, have also been
proposed.
Many of these prior devices have not fully satisfied the demand of consumers
for even
smaller devices that may be worn interlabially by female wearers. In response
thereto, several
manufacturers have produced labial pads that are quite small in size in
comparison to the prior
devices described above. However, the construction of many of these devices
appears to fail to
recognize the wide range of variation that exists among women with regard to
the location of
their vaginal and urethral orifices. For example, some current devices often
locate a significant
portion of the absorbent core in the center of the device with a much less
significant portion of
the absorbent core located in the ends. Such devices afford less protection
for the broad
spectrum of women whose vaginal and urethral orifices are not located in the
center of their
vestibules. Other devices appear to provide a uniform distribution of
absorbent core substantially
throughout the longitudinal length of the device. However, the designs of
inany of these other
devices typically fail to significantly enhance individualized fit and/or
absorbent capacity.
Another factor affecting consumer acceptance is the ease of use, including
disposition of
the labial pad into proper placement and/or removal of the labial pad.
Typically, the wearer
1
CA 02449513 2003-12-03
WO 02/100311 PCT/US02/18264
grasps the labial pad with her fingers and disposes it into proper placement
within her vestibule.
The wearer may also need to grasp the labial pad for removal, particularly if
it is not expelled
during urination. The disposition and/or removal of conventional labial pads
is often
accompanied with a great deal of difficulty. Thus, a need exists for an
improved means which
will facilitate sanitary disposition of a labial pad into an appropriate
position within the vestibule
as well as sanitary removal of a labial pad from the vestibule.
SUMMARY
The present inventors have recognized the deficiencies and problems inherent
in the prior
art and in response thereto conducted intensive research in developing
innovative labial pads.
While conducting their research, the inventors also discovered that at least
one tab extending
outward from the periphery of a labial pad enhanced the ability of a wearer to
sanitarily and
easily dispose a labial pad within the vestibule and/or sanitarily and easily
remove a labial pad
from the vestibule.
In one embodiment of the present invention, an absorbent article is disclosed
as having a
fluid permeable cover, a liquid impermeable baffle and an absorbent. The
absorbent is desirably
situated between the cover and the baffle. The absorbent article is configured
for disposition
within the vestibule of a female wearer. The absorbent article includes a
principal longitudinal
axis, a principal transverse axis, a body-facing surface and a surface opposed
to the body-facing
surface. The absorbent article has a length, a width, a thickness, first and
second spaced apart
longitudinal sides and first and second spaced apart transverse end areas. The
longitudinal sides
extending between the transverse end areas and collectively defining the
periphery of the
absorbent article. Extending laterally outward from at least one longitudinal
side of the absorbent
article is at least one tab.
In another embodiment of the present invention, an absorbent article is
disclosed as
including a liquid impermeable baffle and an absorbent. The absorbent article
is configured for
disposition within the vestibule of a female wearer. The absorbent article has
a principal
longitudinal axis, a principal transverse axis, a body-facing surface and a
surface opposed to the
body-facing surface. The absorbent article has a length, a width, a
tliickness, and first and
second spaced apart longitudinal sides and first and second spaced apart
transverse end areas.
The longitudinal sides extending between the transverse end areas and
collectively defining the
periphery of the absorbent article. Extending laterally outward from at least
one longitudinal side
of the absorbent article is at least one tab.

DESCRIPTION
Turning to the figures of drawing, i. e. , FIGs. 1 through 36, in each of
which similar parts
are identified with like reference characters, FIG. 2 illustrates
diagrammatically an absorbent
article, such as a labial pad, designated generally as 40, disposed within the
vestibule of a
wearer, designated generally as 42 (see also FIG. 1). As used herein, the term
"labial pad"
refers to a device having at least some absorbent components, and which is
specifically
configured for disposition in between the labia majora, extending at least
partially into the
vestibule (42) of a female wearer during use. For purposes of the ensuing
description, the
vestibule (42) is considered to be the region defined within the labia (not
specifically shown in the
figures herein) beginning at about a point lying caudally from the anterior
labial commissure
(44), extending rearward to the posterior labial commissure (46) and bounded
inwardly by the
floor (48) of the vestibule. One of skill in the art fully understands that
there is a wide range of
variation ainong women with respect to the relative size and shape of labia
majora and labia
minora as the same interrelatedly define the contour of the vestibule (42).
For purposes of the
present description, however, such differences will not specifically be
addressed, it being
recognized that in any event the disposition of the absorbent article (40)
into the vestibule (42)
will necessitate placement between the labia majora regardless of any such
consideration
respecting the labia minora. Lying caudally of the vestibule (42) is the
perineum (50) which
leads to the anus (52) in the region of the buttocks (54). Within the
vestibule (42) itself is located
the principal urogenital members whicli, for purposes pertinent here, are
constituted of the
vaginal orifice (56), the urethral orifice (58), and the clitoris (60). Given
the foregoing
simplified review of this anatomical region, and to facilitate the present
description, the vestibule
(42) will be considered generally to be the region between the posterior
labial commissure (46)
and the clitoris (60), for convenience. For a more comprehensive description
of this portion of
the human female anatomy, however, attention is invited to Anatomy of the
Human Body by

Febiger, 1985) at
1571-1581.
As can be seen with reference to the anatomical structure illustrated in FIGs.
1 and 2, the
absorbent article (40) is disposed at least partially within the vestibule
(42) for at least partially
occluding the same respecting fluid flow therefrom. In this regard, the
predominant use of the
absorbent article (40) is for the absorption of menstrual fluid emitted via
the vaginal orifice (56);
although the absorbent article is equally well adapted to serve as a type of
incontinence device for
absorption of urine as occurs upon minor, female incontinence.
The absorbent article (40), a version of which is illustrated in FIG. 3, has a
principal
longitudinal axis (L) which generally runs along the x direction. As used
herein, the term
"longitudinal" refers to a line, axis or direction in the plane of the
absorbent article (40) that is
generally aligned with (e.g., approximately parallel to) a vertical plane that
bisects a standing
female wearer into left and right body halves when the absorbent article is in
use. The
longitudinal direction is generally illustrated in FIG. 3 by the x-axis. The
absorbent article (40)
also has a principal transverse axis (T). The terms "trans verse," "lateral"
or "y direction" as
used herein generally refer to a line, axis or direction that is generally
perpendicular to the
longitudinal direction. The lateral direction is generally illustrated in FIG.
3 by the y-axis. The
"z direction" is typically a line, axis or direction generally parallel to the
vertical plane described
above. The z direction is generally illustrated in FIG. 4 by the z-axis. The
term "upper" refers
generally to an orientation directed toward the wearer's head, while the terms
"lower" or
"downwardly" refer generally to an orientation directed toward the wearer's
feet. For purposes
of discussion herein, each layer of the absorbent article (40), e.g., a fluid
permeable cover (62),
a liquid impermeable baffle (64) and/or an absorbent (66), has an upper or
body-facing surface
and a lower surface also described as the surface opposed to the upper or body-
facing surface.
Turning now to FIG. 5, an absorbent article (40) is illustrated as including a
fluid
permeable cover (62), a liquid impermeable baffle (64) and an absorbent (66)
situated between
the cover and the baffle. As illustrated in FIG. 6, the absorbent (66) has a
first end region (70),
a second end region (72), and a central region (74) disposed between each end
region. The
absorbent article (40) should be of a suitable size and shape that allows at
least a portion of the
absorbent article to be disposed within the vestibule (42) of a female wearer.
In addition, the
absorbent article (40) desirably at least partially occludes and intercepts
the flow of menstrual
fluid, urine or other bodily exudates from the wearer's vaginal orifice (56)
and/or urethral
orifice (58).

WO 02/100311 PCT/US02/18264
The absorbent (66), and thus the absorbent article (40), generally displays a
geometry
extending between spaced apart first (76) and second (78) transverse end
areas. The overall
geometry is completed by noting that the absorbent (66), and thus the
absorbent article (40), also
includes spaced apart first (80) and second (82) longitudinal sides ranging
between the transverse
end areas (76, 78), these collectively sometimes being referred to herein as
the perimetral sides
(i.e., those defining the periphery).
The geometry of the absorbent (66) is a significant factor affecting the
overall size and
effectiveness of the absorbent article (40). In general, the absorbent (66)
has a maximum width
(Wmax), measured along a line laying generally parallel to the principal
transverse axis (T) and
running from one longitudinal side to the opposing longitudinal side (80, 82),
and a minimum
width (Wmin), measured along a line also laying generally parallel to the
principal transverse axis
(T) and running from one longitudinal side to the opposing longitudinal side
(80, 82). The
maximum width (Wmax) of the absorbent (66) typically is no greater than about
30; alternatively,
no greater than about 40; alternatively, no greater than about 50;
alternatively, no greater than
about 60; or alternatively, no greater than about 70 mm. The minimum width
(Wmin) of the
absorbent (66) typically is no less than about 30; alternatively, no less than
about 20;
alternatively, no less than about 10; or alternatively, no less than about 5
mm. Tllus, the
absorbent (66) may have a width ranging between no less than about 5 mm up to
no greater than
about 70 mm; although the approximate width(s) of the absorbent may vary
according to, iiiter
alia, the general design and intended disposition of the absorbent article
(40) within the vestibule
(42) of a female wearer. One of skill in the art will readily appreciate that
certain versions of the
absorbent (66), and thus certain versions of the absorbent article (40), may
have a minimum
width (Wmin) equal to its maximum width (Wmax). In such instances, reference
is generally made
only to the maximum width (Wmax).
The absorbent (66) also has a maximum length (Lmax), measured along a line
laying
generally parallel to the principal longitudinal axis (L) and running from one
transverse end area
to the other transverse end area (76, 78). The maximum length (Lmax) of the
absorbent (66)
typically is no greater than about 40; alternatively, no greater than about
50; alternatively, no
greater than about 60; alternatively, no greater than about 70; alternatively,
no greater than about
80; alternatively, no greater than about 90; or alternatively, no greater than
about 100 mm. The
absorbent (66) may also have a minimum lengtli (Lmin), measured along a line
also laying
generally parallel to the principal longitudinal axis (L) and running from one
transverse end area
to the other transverse end area (76, 78). The minimum length (Lmin) of the
absorbent (66)
typically is no less than about 100; alternatively, no less than about 90;
alternatively, no less than
8
CA 02449513 2003-12-03
WO 02/100311 PCT/US02/18264
about 80; alternatively, no less than about 70; alternatively, no less than
about 60; alternatively,
no less than about 50; or alternatively, no less than about 40 min. Thus, the
absorbent (66) may
have a length ranging between no less than about 40 min up to no greater than
about 100 mm;
although the approximate length(s) of the absorbent may vary according to,
inter alia, the general
design and intended disposition of the absorbent article (40) within the
vestibule (42) of a female
wearer. One of skill in the art will readily appreciate that certain versions
of the absorbent (66),
and thus certain versions of the absorbent article (40), may have a minimum
length (Lmin) equal to
its maximum length (Lmax). In such instances, as illustrated at least in FIGs.
6, 8 and 9, reference
is generally made only to the maximum length (Lmax). Versions of an absorbent
(66), and thus
versions of an absorbent article (40), having a maximum length (Lmax) not
equal to its minimum
length (Lmin) are illustrated at least in FIGs. 7 and 10.
The first end region (70) and the second end region (72) each minimally extend
outwardly
from the central region (74) toward the transverse end areas (76 and 78,
respectively) of the
absorbent (66) a distance of no less than about 30; alternatively, no less
than about 20; or
alternatively, no less than about 10 % of the maximum length (Lmax) of the
absorbent. The first
end region (70) and the second end region (72) each maximally extend outwardly
from the
central region (74) toward the transverse end areas (76 and 78, respectively)
of the absorbent
(66) a distance of no greater than about 20; alternatively, no greater than
about 30; or
alternatively, no greater than about 40 % of the maximum length (Lmax) of the
absorbent. Thus,
the end regions (70, 72) may occupy from a miniinum of about 20 % up to a
maximum of about
80 % of the maximum length (Lmax) of the absorbent (66); although the
approximate size of the
first and second end regions may vary according to, inter alia, the general
design and intended
disposition of the absorbent article (40) within the vestibule (42) of a
female wearer.
The absorbent article (40) is desirably provided witli sufficient capacity to
absorb and
retain the intended amount and type of bodily exudate(s). The absorbent
capacity is provided by
a fluid retentive core or absorbent generally identified as 66. For at least
menstrual fluid, the
absorbent (66) desirably has a minimum capacity of no less than about 19;
alternatively, no less
than about 18; alternatively, no less than about 17; alternatively, no less
than about 16;
alternatively, no less than about 15; alternatively, no less than about 14;
alternatively, no less
than about 13; alternatively, no less than about 12; alternatively, no less
than about 11;
alternatively, no less than about 10; alternatively, no less than about 9;
alternatively, no less than
about 8; alternatively, no less than about 7; alternatively, no less than
about 6; alternatively, no
less than about 5; alternatively, no less than about 4; alternatively, no less
than about 3;
alternatively, no less than about 2; or alternatively, no less than about 1
g/g. The absorbent (66)
9
CA 02449513 2003-12-03
WO 02/100311 PCT/US02/18264
also may have a maximum capacity of no greater than about 5; alternatively, no
greater than
about 6; alternatively, no greater than about 7; alternatively, no greater
than about 8;
alternatively, no greater than about 9; alternatively, no greater than about
10; alternatively, no
greater than about 11; alternatively, no greater than about 12; alternatively,
no greater than about
13; alternatively, no greater than about 14; alternatively, no greater than
about 15; alternatively,
no greater than about 16; alternatively, no greater than about 17;
alternatively, no greater than
about 18; alternatively, no greater than about 19; alternatively, no greater
than about 20;
alternatively, no greater than about 25; or alternatively, no greater than
about 30 g/g. Thus, the
absorbent (66) may have an absorbent capacity ranging between no less than
about 1 g/g up to no
greater than about 30 g/g; although the approximate capacity of the absorbent
may vary
according to, inter alia, the general design and intended disposition of the
absorbent article (40)
within the vestibule (42) of a female wearer. One of skill in the art will
readily realize that the
addition of superabsorbent polymer(s) or coated superabsorbent polymer(s) to
the absorbent (66)
typically has the effect of substantially increasing the absorbent capacity.
Describing the individual eleinents in greater detail, the absorbent (66) has
an upper or
body-facing surface and a lower surface (or surface opposed to the upper or
body-facing surface)
and may include any material capable of absorbing and/or adsorbing and
thereafter retaining the
intended bodily exudate(s). Suitable materials are also generally hydrophilic,
compressible and
conformable. The absorbent (66) may be formed from any of the materials well
known to those
of ordinary skill in the art. Examples of such materials include, but are not
limited to, various
natural or synthetic fibers, multiple plies of creped cellulose wadding,
fluffed cellulose fibers,
rayon or other regenerated cellulose materials, wood pulp fibers or comminuted
wood pulp
fibers, airlaid material, textile fibers, a blend of polyester and
polypropylene fibers, absorbent
foams, absorbent sponges, superabsorbent polymers, coated superabsorbent
polymers, fibrous
bundles or nits, or any equivalent material or combination of materials. Also
suitable for use
would be hydrophobic material that has been rendered hydrophilic according to
any of a number
of known methods for so doing. The total absorbent capacity of the absorbent
(66) should,
however, be compatible with the design exudate loading and the intended use of
the absorbent
article (40). Further, the size and absorbent capacity of the absorbent (66)
may be varied.
Therefore, the dimension, shape, and configuration of the absorbent (66) may
be varied (e.g., the
absorbent may have a varying thickness as illustrated at least in FIGs. 11 and
12, or a
hydrophilic gradient, or may contain superabsorbent polymer(s) and the like).
The absorbent (66) generally has a thickness, caliper or height (H), as
illustrated at least in
FIG. 4, measured along a line lying generally parallel to the z-axis. The
minimum thickness of
CA 02449513 2003-12-03
WO 02/100311 PCT/US02/18264
the absorbent (66) typically is no less than about 9; alternatively, no less
than about 8;
alternatively, no less than about 7; alternatively, no less than about 6;
alternatively, no less than
about 5; alternatively, no less than about 4; alternatively, no less than
about 3; alternatively, no
less than about 2; alternatively, no less than about 1; or alternatively, no
less than about 0.5 mm.
The maximum thickness of the absorbent (66) typically is no greater than about
2; alternatively,
no greater than about 3; alternatively, no greater than about 4;
alternatively, no greater than
about 5; alternatively, no greater than about 6; alternatively, no greater
than about 7;
alternatively, no greater than about 8; alternatively, no greater than about
9; or alternatively, no
greater than about 10 mm. Thus, the absorbent (66) may have a thickness of
about 10 mm or
less; although the approximate thickness of the absorbent may vary according
to, inter alia, the
general design and intended disposition of the absorbent article (40) within
the vestibule (42) of a
female wearer.
The absorbent (66) desirably also has a relatively low density which is deemed
desirable
for comfort. Generally, the absorbent has a density of less than about 0.5
g/cc. Stated
differently, the absorbent (66) typically has a maximum density of no greater
than about 0.5;
alternatively, no greater than about 0.4; alternatively, no greater than about
0.3; alternatively, no
greater than about 0.2; alternatively, no greater than about 0.1;
alternatively, no greater than
about 0.09; alternatively, no greater than about 0.08; alternatively, no
greater than about 0.07;
alternatively, no greater than about 0.06; alternatively, no greater than
about 0.05; alternatively,
no greater than about 0.04; alternatively, no greater than about 0.03; or
alternatively, no greater
than about 0.02 g/cc. The absorbent (66) generally also has a minimum density
of typically no
less than about 0.01; alternatively no less than about 0.02; alternatively, no
less than about 0.03;
alternatively, no less than about 0.04; alternatively, no less than about
0.05; alternatively, no less
than about 0.06; alternatively, no less than about 0.07; alternatively, no
less than about 0.08;
alternatively, no less than about 0.09; alternatively, no less than about 0.1;
alternatively, no less
than about 0.2; alternatively, no less than about 0.3; or alternatively, no
less than about 0.4 g/cc.
Thus, the density of the absorbent (66) may range up to about 0.5 g/cc;
although the
approximate density of the absorbent may vary according to, irater alia, the
general design and
intended disposition of the absorbent article (40) within the vestibule (42)
of a female wearer.
The absorbent (66) also desirably has a basis weight of less than about 600
grams per
square meter (gsm). Stated differently, the absorbent (66) typically has a
maximum basis weight
of no greater than about 600; alternatively, no greater than about 500;
alternatively, no greater
than about 400; alternatively, no greater than about 300; alternatively, no
greater than about 200;
or alternatively, no greater than about 100 gsm. Generally, the absorbent (66)
also has a
11
CA 02449513 2003-12-03
WO 02/100311 PCT/US02/18264
minimum basis weight of typically no less than about 0.1; alternatively, no
less than about 50;
alternatively, no less than about 100; alternatively, no less than about 150;
alternatively, no less
than about 200; alternatively, no less than about 250; alternatively, no less
than about 300;
alternatively, no less than about 350; alternatively, no less than about 400;
alternatively, no less
than about 450; alternatively, no less than about 500; or alternatively, no
less than about 550
gsm. Thus, the absorbent (66) may have a basis weight of about 600 gsm or
less; although the
approximate basis weight of the absorbent may vary according to, iiiter alia,
the general design
and intended disposition of the absorbent article (40) within the vestibule
(42) of a female wearer.
A specific exainple of a suitable absorbent would be similar to a coform
material made of a
blend of polypropylene and cellulose fibers and used in KOTEX maxi
pantiliners and obtainable
from Kimberly-Clark Corporation, Neenah, WI, USA.
The optional baffle (64) typically resides on the lower surface of the
absorbent (66) and
may be constructed from any desired material that is liquid-impermeable.
Desirably, the baffle
(64) will permit the passage of air and moisture vapor out of the absorbent
(66), while blocking
the passage of bodily fluid(s). An example of a suitable baffle material is a
micro-embossed,
polymeric film, such as polyethylene, polypropylene or polyester, having a
minimum thickness
of no less than about 0.025 nun and a maximum thickness tof no greater than
about 0.13 mm.
Bicomponent films can also be used, as well as woven and nonwoven fabrics
which have been
treated to render them liquid-impermeable. An example of another suitable
material is a closed
cell polyolefin foam. A closed cell polyethylene foam may also work well.
The baffle (64) may be maintained in secured relation with the absorbent (66)
by bonding
all or a portion of the adjacent surfaces to one another. A variety of bonding
methods known to
one of skill in the art may be utilized to achieve any such secured relation.
Examples of such
methods include, but are not limited to, ultrasonics, thermal bonding, or the
application of
adhesives in a variety of patterns between the two adjoining surfaces. A
specific example of a
baffle material would be similar to a polyethylene film used on KOTEX
pantiliners and
obtainable from Pliant Corporation, Schaumburg, IL, USA.
The optional fluid permeable cover (62) has an upper surface and a lower
surface, with
the upper surface typically contacting the body of the wearer and receiving
bodily exudate(s).
The cover (62) desirably is made of a material that is flexible and non-
irritating to the tissues
within the vestibule (42) of a female wearer. As used herein, the term
"flexible" is intended to
refer to materials which are compliant and readily conform to the bodily
surface(s) or respond by
easily deforming in the presence of external forces.
12
CA 02449513 2003-12-03
WO 02/100311 PCT/US02/18264
The cover (62) is provided for comfort and conformability and functions to
direct bodily
exudate(s) away from the body and toward the absorbent (66). The cover (62)
should retain little
or no liquid in its structure so that it provides a relatively comfortable and
non-irritating surface
next to the tissues within the vestibule (42) of a female wearer. The cover
(62) can be
constructed of any woven or nonwoven material which is also easily penetrated
by bodily fluids
contacting its surface. Examples of suitable materials include rayon, bonded
carded webs of
polyester, polypropylene, polyethylene, nylon, or other heat-bondable fibers,
polyolefins, such as
copolymers of polypropylene and polyethylene, linear low-density polyethylene,
aliphatic esters
such as polylactic acid, finely perforated film webs and net material also
work well. A specific
example of a suitable cover material would be similar to a bonded carded web
made of
polypropylene and polyethylene used as a cover stock for KOTEX pantiliners
and obtainable
from Sandler Corporation, Germany. Other examples of suitable materials are
composite
materials of a polymer and a nonwoven fabric material. The composite materials
are typically in
the form of integral sheets generally formed by the extrusion of a polymer
onto a web of
spunbond material. The fluid permeable cover (62) can also contain a plurality
of apertures (not
shown) formed therein which are intended to increase the rate at which bodily
fluid(s) can
penetrate into the absorbent (66).
A physiologically hydrous cover material is also suitable for use. As used
herein, the term
"phys iologically hydrous" is intended to connote a cover material which
maintains a suitably
moist interface between the tissues of the vestibule (42) and the absorbent
article (40) when
disposed in that vestibular environment; one that is benign respecting the
requirements of comfort
associated with the interposition of fabric or fabric-like structures within
the moist tissue
environment of the vestibule, keeping in mind as well the self-evident factor
that the absorbent
article is receiving bodily fluid(s) migrating through the vestibule and must
conduct the same to
the absorbent (66). Thus, while not "hydrous " in the classic sense prior to
use (inasmuch as the
cover will be dry at that time) the cover (62) maintains (or at least does not
interfere with the
maintenance of) the proper moisture level or balance required within the
vestibule (42).
The cover (62) can also have at least a portion of the surface treated with a
surfactant to
render the cover more hydrophilic. This results in permitting the insulting
bodily fluid(s) to more
readily penetrate the cover (62). The surfactant may also diminish the
likelihood that the
insulting bodily fluid(s), such as menstrual fluid, will flow off the cover
(62) rather than being
absorbed by the absorbent (66). One suitable approach provides for the
surfactant to be
substantially evenly distributed across at least a portion of the upper
surface of the cover (62) that
overlays the upper surface of the absorbent (66).
13
CA 02449513 2003-12-03
WO 02/100311 PCT/US02/18264
The cover (62) may be maintained in secured relation with the absorbent (66)
by bonding
all or a portion of the adjacent surfaces to one another. A variety of bonding
metliods known to
one of skill in the art may be utilized to achieve any such secured relation.
Examples of such
methods include, but are not limited to, the application of adhesives in a
variety of patterns
between the two adjoining surfaces, entangling at least portions of the
adjacent surface of the
absorbent with portions of the adjacent surface of the cover, or fusing at
least portions of the
adjacent surface of the cover to portions of the adjacent surface of the
absorbent.
The cover (62) typically resides on the upper surface of the absorbent (66),
but
alternatively can surround and partially or entirely enclose the absorbent.
Alternatively, the
cover (62) and the baffle (64) can have peripheries which extend outward
beyond the periphery
of the absorbent (66) and can be peripherally joined together to form an edge
(84), as illustrated
at least in FIG. 5. Utilizing known techniques, such as, for example, gluing,
crimping, hot-
sealing or the like, the edge (84) may be formed either entirely, so that the
entire periphery of the
absorbent (66) is circumscribed by their joinder, or the cover (62) and the
baffle (64) can be
partially peripherally joined. To minimize the possibility of irritation
and/or discomfort to the
wearer of the absorbent article (40), it is desired that the edge (84) and at
least the area of the
absorbent article immediately adjacent the edge be soft, compressible and
conformable.
Desirably, any edge (84) so formed shall have a width no greater than about
10; alternatively, no
greater than about 9; alternatively, no greater than about 8; alternatively,
no greater than about 7;
alternatively, no greater than about 6; alternatively, no greater than about
5; alternatively, no
greater than about 4; alternatively, no greater than about 3; alternatively,
no greater than about 2;
or alternatively, no greater than about 1 nun. In addition, any edge (84) so
formed shall
desirably have a width of no less than about 0.5; alternatively, no less than
about 1; alternatively,
no less than about 2; alternatively, no less than about 3; alternatively, no
less than about 4;
alternatively, no less than about 5; alternatively, no less than about 6;
alternatively, no less than
about 7; alternatively, no less than about 8; or alternatively, no less than
about 9 mm. Thus, any
edge (84) so formed may have a width ranging from no less than about 0.5 mm up
to no greater
than about 10 mm; although the approximate width of any edge may vary
according to, inter
alia, the general design and intended disposition of the absorbent article
(40) within the vestibule
(42) of a female wearer. In other versions, the cover (62) and/or the baffle
(64) can have a
periphery that is coterminous with the periphery of the absorbent (66).
Positioned either on or substantially parallel to the principal longitudinal
axis (L) of the
absorbent (66), is, optionally, a desired axis of flexure (F). A desired axis
of flexure (F)
generally runs in the longitudinal direction, i. e. , along the x direction,
and may be off center
14
CA 02449513 2003-12-03
WO 02/100311 PCT/US02/18264
from the principal longitudinal axis (L) a distance of no greater than about
10; alternatively, no
greater than about 9; alternatively, no greater than about 8; alternatively,
no greater than about 7;
alternatively, no greater than about 6; alternatively, no greater than about
5; alternatively, no
greater than about 4; alternatively, no greater than about 3; alternatively,
no greater than about 2
mm; or alternatively, no greater than about 1 mm. Desirably, a desired axis of
flexure (F) is
aligned along the principal longitudinal axis (L). A desired axis of flexure
(F) typically
minimally extends longitudinally no less than about 90; alternatively, no less
than about 80;
alternatively, no less than about 70; alternatively, no less than about 60;
alternatively, no less
than about 50; or alternatively, no less than about 40 % of the maximum length
(Lmax) of the
absorbent (66). A desired axis of flexure (F) typically extends longitudinally
no greater than
about 50; alternatively, no greater than about 60; alternatively, no greater
than about 70;
alternatively, no greater than about 80; alternatively, no greater than about
90; or alternatively,
no greater than about 100 % of the maximum length (Lmax) of the absorbent
(66). A desired axis
of flexure (F) may result naturally from the dimensions, shape, and/or
configuration of the
absorbent (66), or the absorbent may be imparted with a weakened axis or
region to create a
desired axis of flexure. A desired axis of flexure (F) may also be formed by
any of the
techniques known to one of skill in the art, including, for example, scoring,
pre-folding, slitting,
embossing, or the like. Although a desired axis of flexure (F) is described
herein as residing in
the absorbent (66), one of skill in the art will readily appreciate that a
desired axis of flexure may
be formed in either the cover (62), the baffle (64) and/or the absorbent; the
cover and the baffle;
the cover and the absorbent; or the baffle and the absorbent. When present, a
desired axis of
flexure (F) typically allows an absorbent article (40) to be folded more
easily prior to disposition
witliin the vestibule (42) of a female wearer.
The absorbent article (40) also has a thickness, caliper or height (H), as
illustrated at least
in FIGs. 4 and 5, measured along a line laying generally parallel to the z-
axis. The minimum
thickness of the absorbent article (40) typically is no less than about 9;
alternatively, no less than
about 8; alternatively, no less than about 7; alternatively, no less than
about 6; alternatively, no
less than about 5; alternatively, no less than about 4; alternatively, no less
than about 3;
alternatively, no less than about 2; alternatively, no less than about 1; or
alternatively, no less
than about 0.5 mm. The maximum thickness of the absorbent article (40)
typically is no greater
than about 1; alternatively, no greater than about 2; alternatively, no
greater than about 3;
alternatively, no greater than about 4; alternatively, no greater than about
5; alternatively, no
greater than about 6; alternatively, no greater than about 7; alternatively,
no greater than about 8;
alternatively, no greater than about 9; or alternatively, no greater than
about 10 mm. Thus, the
CA 02449513 2003-12-03
WO 02/100311 PCT/US02/18264
absorbent article (40) may have a thickness of about 10 mm or less; although
the approximate
thickness of the absorbent article may vary according to, itater alia, the
general design and
intended disposition of the absorbent article within the vestibule (42) of a
female wearer.
LONGITUDINAL SIDE(S)
The absorbent article (40) typically is folded along an axis lying on or
positioned parallel
to the principal longitudinal axis (L), as illustrated at least in FIGs. 12,
13 and 14, prior to
disposition within the vestibule (42) of the female wearer. When folded along
such an axis, the
absorbent article (40) will form a recess (92) which protects the wearer's
finger(s) from soiling
when the absorbent article is disposed witliin the vestibule (42). Once
inserted, the absorbent
article (40) may have a tendency to unfold in an attempt to fill the vestibule
and thus maintain the
upper surface of the absorbent article in contact with the tissues of the
vestibule (42). The
absorbent article (40) may be resiliently biased along the axis about which it
is folded to increase
the tendency of the absorbent article to unfold. Alternatively, the absorbent
(66) of the absorbent
article (40) may be thicker along its longitudinal edges, as illustrated at
least in FIGs. 11 and 12,
thus also demonstrating a biasing effect, if desired, which is typically
intended to allow the upper
surface of the absorbent article (40) to contact the tissues of the vestibule
(42). An absorbent
article (40) as described herein, however, does not necessarily require any
additional features to
maintain contact with the tissues of the vestibule (42) of the female wearer.
The naturally moist
surfaces of the tissues of the vestibule (42) typically demonstrate a tendency
to maintain contact
with the upper surface of the absorbent article (40).
As noted above, the wearer may fold the absorbent article (40) along an axis
lying on or
positioned parallel to the principal longitudinal axis (L) prior to
disposition within the vestibule
(42). The wearer may, therefore, hold the folded absorbent article (40) near
the longitudinal
sides as illustrated at least in FIG. 14. The absorbent article (40) may then
be disposed within
the vestibule (42) by the wearer exerting a force with a finger or fingers
positioned in the recess
(92) formed by the folded absorbent article.
Suitable for use with the absorbent articles described herein would be at
least one
placement and removal tab (94) extending outward from at least one
longitudinal side of an
absorbent article (40). While one such tab (94) is theorized as working
effectively in the
placement and removal of an absorbent article (40) such as a labial pad, it is
believed that at least
two tabs (94 and 94') , i.e., one tab extending from each longitudinal side
(80, 82) of the
absorbent article, are also effective in the placement and removal of an
absorbent article.
Consequently, in the discussion that follows, unless otherwise noted, the
absorbent article (40)
16
CA 02449513 2003-12-03
WO 02/100311 PCT/US02/18264
will have at least two tabs (94, 94') . While it is not necessary that the
tabs (94, 94') be
identical, or, more properly, mirror images one of the other, they desirably
are. Thus the
description of the first will be a description of any other tab. Discussion of
any other tab will,
therefore, be omitted for clarity of exposition. Corresponding elements are
indicated in the
drawings by reference numerals and primed reference numerals. In addition,
although illustrated
with the various versions of the absorbent article (40) disclosed herein, it
will be understood that
the tabs (94, 94') herein may be incorporated into a number of other suitably
shaped and
dimensioned labial pads. Such suitable shapes and dimensions include, but are
not limited to,
rectangular, ovoid-like, elliptical, trapezoidal, circular-like, triangular,
square-shaped, teardrop-
like, diamond-shaped, butterfly, pear-shaped, heart-shaped or a variety of
combinations thereof.
Extending outward from a longitudinal side (80, 82) of an absorbent article
(40), the tab
(94) can be of any suitable configuration. Non-limiting examples of shapes for
the tab (94)
include, ovoid, elliptical, trapezpoidal, rectangular, triangular, diamond-
shaped, circular, semi-
circular, or any combination of the above. The tab (94) may be integrally
formed with the
absorbent article (40) or it may be a separate element joined to the absorbent
article. One of skill
in the art will readily appreciate that when the tab (94) is a separate
element joined to the
absorbent article (40), the tab may be so joined by a number of known methods
including melt
fusion, adhesion, or other joining means. The phrase "integrally formed" is
intended to indicate
that the tab (94) is not joined to the absorbent article (40), but rather is
an extension of: the cover
(62), the baffle (64), and/or the absorbent (66); the cover and the baffle;
the cover and the
absorbent; or the baffle and the absorbent.
The tab (94) has a length (), measured along a line laying generally parallel
to the
principal longitudinal axis (L) of an absorbent article (40), and a width (w),
measured along a
line laying generally parallel to the principal transverse axis (T) of an
absorbent article. The tab
(94) has sufficient dimensions to aid the female user in disposition of the
absorbent article (40)
within the vestibule (42) and, optionally, removal of the absorbent article
from the vestibule.
The phrase "s ufficient dimensions" is intended to indicate that the tab (94)
can be grasped
between the index finger and the thumb or, if there are, for example, two
tabs, between the index
finger and the thumb and the middle finger and the index finger. Typically,
the length () of the
tab (94) is no greater than the maximum lengtli (Lmax) of the absorbent (66).
More specifically,
the length () of the tab (94) typically is no greater than about 100;
alternatively, no greater than
about 90; alternatively, no greater than about 80; alternatively, no greater
than about 70;
alternatively, no greater than about 60; alternatively, no greater than about
50; alternatively, no
greater than about 40; alternatively, no greater than about 30; alternatively,
no greater than about
17
CA 02449513 2003-12-03
WO 02/100311 PCT/US02/18264
20; alternatively, no greater than about 10; or alternatively, no greater than
about 5 mm. Stated
differently, the length () of the tab (94) is typically no greater than about
100; alternatively, no
greater than about 90; alternatively, no greater than about 80; alternatively,
no greater than about
70; alternatively, no greater than about 60; alternatively, no greater than
about 50; alternatively,
no greater than about 40; alternatively, no greater than about 30;
alternatively, no greater than
about 20; or alternatively, no greater than about 10 % of the maximum length
(Lmax) of the
absorbent (66). The length () of the tab (94) typically is no less than about
1; alternatively, no
less than abput 5; alternatively, no less than about 10; alternatively, no
less than about 20;
alternatively, no less than about 30; alternatively, no less than about 40;
alternatively, no less
than about 50; alternatively, no less than about 60; alternatively, no less
than about 70;
alternatively, no less than about 80; or alternatively, no less than about 90
mm. One of skill in
the art will readily appreciate that the length () of the tab (94) may vary
according to, inter alia,
the general design and intended disposition of the absorbent article within
the vestibule (42) of a
female user.
In addition to having a length (), the tab (94) also has a width (w). The
width (w) of the
tab (94) typically is no greater than about 50; alternatively, no greater than
about 40;
alternatively, no greater than about 30; alternatively, no greater than about
20; alternatively, no
greater than about 10; alternatively, no greater than about 7.5;
alternatively, no greater than
about 5; alternatively, no greater than about 2.5; or alternatively, no
greater than about 1 mm.
The width (w) of the tab (94) typically is no less than about 1;
alternatively, no less than about
2.5; alternatively, no less than about 5; alternatively, no less than about
7.5; alternatively, no less
than about 10; alternatively, no less than about 20; alternatively, no less
than about 30; or
alternatively, no less than about 40 mm. One of skill in the art will readily
appreciate that the
width (w) of the tab (94) may vary according to, inter alia, the general
design and intended
disposition of the absorbent article within the vestibule (42) of a female
user.
The dimensions of the tab (94) are limited only by the stress-strain
properties of the tab
material(s). Desirably any material used in the tabs (94, 94') is soft,
compressible and
conformable and thus similar to the material used in the fluid permeable cover
(62), the liquid
impermeable baffle (64) and/or the absorbent (66). Any such material desirably
minimizes the
possibility of irritation and/or discomfort to the wearer of the absorbent
article (40).
The tab (94) of the present invention may be positioned in a variety of
locations along the
longitudinal side (80, 82) of an absorbent article (40). With regard to the
absorbent articles (40)
described herein, the tab (94) may be located in either the first end region
(70), the second end
region (72) or the central region (74). A second tab (94') could at the same
time be located
18
CA 02449513 2003-12-03
WO 02/100311 PCT/US02/18264
along the opposing longitudinal side (80, 82) in either the first end region
(70), the second end
region (72) or the central region (74). Generally, when a tab (94) extends
outward from a
longitudinal side (80, 82) of a particular region (70, 72, 74), any second tab
(94') typically
extends outward from the corresponding region (70, 72, 74) of the opposing
longitudinal side
(80, 82). It should also be noted that, depending on the length () of the tab
(94), the tab may
cover more than one of the regions (70, 72, 74) described herein. The tabs
(94, 94') as
described herein offer a female wearer the opportunity to grasp the tabs to
aid in the disposition
of a labial pad into the vestibule. In addition, the tabs (94, 94') also offer
a female wearer the
opportunity to grasp the tabs to aid in the removal of a labial pad and thus
minimize the
likelihood that the female wearer's finger(s) will come into contact with the
body-facing surface
of the possibly soiled labial pad.
Referring to FIGs. 15 through 20, various versions of an absorbent article
(40) are
illustrated having at least one tab (94, 94') positioned along each
longitudinal side (80, 82).
FIG. 21 illustrates an absorbent article (40) having one tab (94, 94')
positioned along each
longitudinal side. Each tab (94, 94') has an integrally formed cover (62) and
baffle (64). While
the cover (62) and baffle (64) in FIG. 21 are integrally formed, each tab (94,
94') has a tab
absorbent (96, 96') that is not integrally formed with the absorbent (66).
Generally, the material
of the tab absorbent (96, 96') is similar to the material of the absorbent
(66). The presence of
absorbent material in a tab typically increases the absorbent capacity of the
absorbent article.
FIG. 22 is a cross-sectional view of the absorbent (40) article of FIG. 21
taken along line 22 -
22.
FIG. 23 illustrates an absorbent article (40) having one tab (94, 94') -
positioned along each
longitudinal side. Each tab (94, 94') has an integrally formed cover (62),
baffle (64) and
absorbent (66); however, for purposes of description, the absorbent extending
outward of the
longitudinal side is referred to as the tab absorbent (96, 96') . FIG. 24 is a
cross-sectional view
of the absorbent article (40) of FIG. 23 taken along line 24 - 24.
FIG. 25 illustrates an absorbent article (40) having one tab (94, 94)
positioned along each
longitudinal side. Each tab (94, 94') has an integrally formed cover (63) and
baffle (64). FIG.
26 is a cross-sectional view of the absorbent article (40) of FIG. 25 taken
along line 26 - 26.
TRANSVERSE END AREA(S)
Although previously described herein as typically being folded along an axis
lying on or
positioned parallel to the principal longitudinal axis, an absorbent article
(40) may also be folded
along an axis lying on or positioned parallel to the principal transverse axis
(T) prior to
19
CA 02449513 2003-12-03
WO 02/100311 PCT/US02/18264
disposition within the vestibule (42) of the female wearer. When folded along
such an axis, the
absorbent article (40) typically still forms a recess (92) which protects the
wearer's finger(s)
from soiling when the absorbent article is disposed witliin the vestibule (42)
(see FIGs. 27 and
28). Once inserted, the absorbent article (40) may have a tendency to unfold
in an attempt to fill
the vestibule and thus maintain the upper surface of the absorbent article in
contact with the
tissues of the vestibule (42). The absorbent article (40) may be resiliently
biased along the axis
about which it is folded to increase the tendency of the absorbent article to
unfold. Alternatively,
the absorbent (66) of the absorbent article (40) may be thicker along its
transverse end areas (76,
78) thus also demonstrating a biasing effect, if desired, which is typically
intended to allow the
upper surface of the absorbent article (40) to contact the tissues of the
vestibule (42). An
absorbent article (40) as described herein, however, does not necessarily
require any additional
features to maintain contact with the tissues of the vestibule (42) of the
female wearer. The
naturally moist surfaces of the tissues of the vestibule (42) typically
demonstrate a tendency to
maintain contact with the upper surface of the absorbent article (40).
Suitable for use with certain versions of the absorbent articles described
herein would be at
least one placement and removal tab (94) extending outward from the periphery
of at least one
transverse end area (76, 78) of an absorbent article (40). While one such tab
(94) is theorized as
working effectively in the placement and removal of an absorbent article (40)
such as a labial
pad, it is believed that at least two tabs (94 and 94') , i.e., one tab
extending from the periphery
of each transverse end area (76, 78) of the absorbent article, are also
effective in the placement
and removal of an absorbent article. Consequently, in the discussion that
follows, unless
otherwise noted, the absorbent article (40) will have at least two tabs (94,
94') . While it is not
necessary that the tabs (94, 94') be identical, or, more properly, mirror
images one of the other,
they desirably are. Thus the description of the first will be a description of
any other tab.
Discussion of any other tab will, therefore, be omitted for clarity of
exposition. Corresponding
elements are indicated in the drawings by reference numerals and primed
reference numerals. In
addition, although illustrated with certain versions of the absorbent article
(40) disclosed herein,
it will be understood that the tabs (94, 94') herein may be incorporated into
a number of other
suitably shaped and dimensioned labial pads. Such suitable shapes and
dimensions include, but
are not limited to, rectangular, ovoid-like, elliptical, trapezoidal, circular-
like, triangular, square-
shaped, teardrop-like, diamond-shaped, butterfly, pear-shaped, heart-shaped or
a variety of
combinations thereof.
Extending outward from the periphery of a transverse end area (76, 78) of an
absorbent
article (40), the tab (94) can be of any suitable configuration. Non-limiting
examples of shapes
CA 02449513 2003-12-03
WO 02/100311 PCT/US02/18264
for the tab (94) include, ovoid, elliptical, trapezoidal, rectangular,
triangular; diamond-shaped,
circular, semi-circular, or any combination of the above. The tab (94) may be
integrally forined
with the absorbent article (40) or it may be a separate element joined to the
absorbent article.
One of skill in the art will readily appreciate that when the tab (94) is a
separate element joined to
the absorbent article (40), the tab may be so joined by a number of known
methods including
nlelt fusion, adhesion, or other joining means. The phrase "integrally formed"
is intended to
indicate that the tab (94) is not joined to the absorbent article (40), but
rather is an extension of:
the cover (62), the baffle (64), and/or the absorbent (66); the cover and the
baffle; the cover and
the absorbent; or the baffle and the absorbent.
The tab (94) has a length (), measured along a line laying generally parallel
to the
principal transverse axis (T).of an absorbent article (40), and -a width (w),
measured along a line
laying generally parallel to the principal longitudinal axis (L) of an
absorbent article (see FIGs.
29 and 30). The tab (94) has sufficient dimensions to aid the female user in
disposition of the
absorbent article (40) within the vestibule (42) and, optionally, removal of
the absorbent article
from the vestibule. The phrase "s ufficient dimensions" is intended to
indicate that the tab (94)
can be grasped between the index finger and the thumb or, if there are, for
example, two tabs,
between the index finger and the thumb and the middle finger and the index
finger. Typically,
the length () of the tab (94) is no greater than the maximum width (Wmax) of
the absorbent (66).
More specifically, the length () of the tab (94) typically is no greater than
about 70;
alternatively, no greater than about 60; alternatively, no greater than about
50; alternatively, no
greater than about 40; alternatively, no greater than about 30; alternatively,
no greater than about
20; alternatively, no greater than about 10; or alternatively, no greater than
about 5 mm. Stated
differently, the length () of the tab (94) is typically no greater than about
100; alternatively, no
greater than about 90; alternatively, no greater than about 80; alternatively,
no greater than about
70; alternatively, no greater than about 60; alternatively, no greater than
about 50; alternatively,
no greater than about 40; alternatively, no greater than about 30;
alternatively, no greater than
about 20; or alternatively, no greater than about 10 % of the maximum width
(Wmax) of the
absorbent (66). The length () of the tab (94) typically is no less than about
1; alternatively, no
less than about 5; alternatively, no less than about 10; alternatively, no
less than about 20;
alternatively, no less than about 30; alternatively, no less than about 40;
alternatively, no less
than about 50; or alternatively, no less than about 60 min. One of skill in
the art will readily
appreciate that the length () of the tab (94) may vary according to, inter
alia, the general design
and intended disposition of the absorbent article within the vestibule (42) of
a female user.

In addition to having a lengtli (), the tab (94) also has a widtli (w) (see
FIGs. 29 and 30).
The width (w) of the tab (94) typically is no greater than about 50;
alternatively, no greater than
about 40; alternatively, no greater than about 30; alternatively, no greater
than about 20;
alternatively, no greater than about 10; alternatively, no greater than about
7.5; alternatively, no
greater than about 5; alternatively, no greater than about 2.5; or
alternatively, no greater than
about 1 nun. The width (w) of the tab (94) typically is no less than about 1;
alternatively, no less
than about 2.5; alternatively, no less than about 5; alternatively, no less
than about 7.5;
alternatively, no less than about 10; alternatively, no less than about 20;
alternatively, no less
than about 30; or alternatively, no less than about 40 mm. One of skill in the
art will readily
appreciate that the width (w) of the tab (94) may vary according to, irater
alia, the general design
and intended disposition of the absorbent article within the vestibule (42) of
a female user.
The dimensions of the tab (94) are limited only by the stress-strain
properties of the tab
material(s). Desirably any material used in the tabs (94, 94') is soft,
compressible and
conformable and thus similar to the material used in the fluid permeable cover
(62), the liquid
impermeable baffle (64) and/or the absorbent (66). Any such material desirably
minimizes the
possibility of irritation and/or discomfort to the wearer of the absorbent
article (40).
The tab (94) of the present invention may be positioned in a variety of
locations along the
periphery of a transverse end area (76, 78) of an absorbent article (40).
Generally, when a tab
(94) extends outward from the periphery of a transverse end area (76, 78) of
an absorbent article
(40), any second tab (94') typically extends outward from the periphery of the
opposing
transverse end area (76, 78). The tabs (94, 94') as described herein offer a
female wearer the
opportunity to grasp the tabs to aid in the disposition of a labial pad into
the vestibule. In
addition, the tabs (94, 94') also offer a female wearer the opportunity to
grasp the tabs to aid in
the removal of a labial pad and thus minimize the likelihood that the female
wearer's finger(s)
will come into contact with the body-facing surface of the possibly soiled
labial pad.
FIG. 31 illustrates an absorbent article (40) having at least one tab (94,
94') positioned
along the periphery of each transverse end area (76, 78). Each tab (94, 94')
has an integrally
formed cover (62) and baffle (64). While the cover (62) and baffle (64) in
FIG. 31 are integrally
formed, each tab (94, 94) has a tab absorbent (96, 96') that is not integrally
formed with the
absorbent (66). Generally, the material of the tab absorbent (96, 96') is
similar to the material
of the absorbent (66). The presence of absorbent material in a tab typically
increases the
absorbent capacity of the absorbent article. FIG. 32 is a cross-sectional view
of the absorbent
(40) article of FIG. 31 taken along line 32 - 32.

FIG. 33 illustrates an absorbent article (40) having at least one tab (94,
94') positioned
along the periphery of each transverse end area (76, 78). Each tab (94, 94')
has an integrally
formed cover (62), baffle (64) and absorbent (66); however, for purposes of
description, the
absorbent extending outward of the periphery of a transverse end area (76, 78)
is referred to as
the tab absorbent (96, 96') . FIG. 34 is a cross-sectional view of the
absorbent article (40) of
FIG. 33 taken along line 34 - 34.
FIG. 35 illustrates an absorbent article (40) having one tab (94, 94')
positioned along the
periphery of each transverse end area (76, 78). Each tab (94, 94') has an
integrally formed
cover (63) and baffle (64). FIG. 36 is a cross-sectional view of the absorbent
article (40) of FIG.
35 taken along line 36 - 36.
Although various versions or embodiments of the present invention have been
disclosed
and described in considerable detail, other embodiments are possible.
Consequently, the spirit
and scope of the appended claims should not be limited to the illustration and
description of the
various embodiments contained herein.
