IMPLEMENT FOR USE WITH A CLEANING SHEET
Field
The present invention relates to an implement wlzich may be used in
conjunction
with a cleaning sheet for cleaning household fabric-based materials including
but not
limited to upholstery, carpet, draperies, children's fabric based toys such as
stuffed
animals and the like, automotive fabric-based materials, recreational vehicle
and water
transport fabric-based materials (including but not limited to motor homes,
tent trailers,
recreational boats, cruise ships, etc.) as well as fabric-based materials
found in institutions
(including but not limited to hospitals, schools, etc.) and fabric-based
materials found in
commercial sites (including but not limited to hotels, restaurants, office
buildings,
manufacturing sites, etc.). The present invention also relates to a kit
comprising the
implement of the present invention and a cleaning sheet for cleaning household
fabric-
based materials. The invention further relates to a method for cleaning
household fabric-
based materials utilizing the implement of the present invention.
Background
One difficulty associated with utilizing a cleaning sheet by itself for
cleaning
fabric-based materials around the house is that in many instances a user may
have to exert
pressure on the cleaning sheet especially when cleaning larger surfaces. This
may create
stress on the hand and wrist. Utilizing the cleaning sheet in conjunction with
the
implement of the present invention may help reduce this stress. The implement
includes
an ergonomically friendly design. Additionally, the implement of the present
invention
allows for more efficient spot treatment of the fabric. Furthermore, utilizing
the cleaning
sheet in conjunction with the implement of the present invention allows for
the more
efficient treatment of the fabric without having to subject the fabric to a
laundering or dry
cleaning process. Yet further, when used in conjunction with a moistened
cleaning sheet,
the implement can help provide more efficient delivery and penetration of the
solution
into the fabric to help facilitate removal of soil. This and other features,
aspects,
advantages, and variations of the present invention will become evident to
those skilled in
the art from a reading of the present disclosure with the appended claims and
are covered
within the scope of the claims.

Cleaning Implement
Referring to FIGS. 1- 8, one non-limiting embodiment of the cleaning implement
of the present invention is shown. Cleaning implement 10 is comprised of
handle 20
connected to cleaning head 30. Handle 20 may be comprised of a single solid
component. Alternatively, handle 20 may be comprised of one or more components
which are joined together. Handle 20 includes an upper area 21 and a lower
area 22.
Cleaning head 30 is comprised of a top and a bottom (not shown). The lower
area 22 of
handle 20 is connected to the top of cleaning head 30. Handle 20 may be
stationary
and/or may be capable of pivoting and/or rotating or a combination thereof.
The upper area 21 of handle 20 may include an indentation 23 on one or both
ends
of the upper area 21. While not wishing to be limited by theory, it is
believed that
indentations 23 facilitate gripping of handle 20 and provide a comfortable fit
for the
user's fingers. In one non-limiting example, indentation 23 may be about 0.25
inches
(6.35 mm) in depth and may be located about 3.5 inches (8.9 cm) from the
center of
handle 20 as measured in the longitudinal direction of the handle.
Upper area 21 of handle 20 may be comprised of a single unit. Alternatively,
upper area 21 of handle 20 may be comprised of more than one component such as
shown in FIG. 7. Referring to FIG. 7, upper area 21 is comprised of top
component 210
and bottom component 211 which are joined together. Bottom component 211 is
joined
to lower area 22 of handle 20.
In one non-limiting example, top component 210 of upper area 21 of handle 20
may be comprised of a flexible polymer such as thermoplastic elastomer
("TPE"). The
CA 02601270 2007-09-10
WO 2006/110792 PCT/US2006/013587
top component 210 may be about 0.093 inches (2.36 mm) or less in thickness.
The
flexible polymer may be opaque, translucent, transparent, or a combination
thereof. The
bottom component 211 of upper area 21 of handle 20 may be made out of a rigid
polymer
non-limiting examples of which include polypropylene and acrylonitrile-
butadiene-
styrene ("ABS") or combinations thereof. The bottom component 211 may be about
0.25
inches (6.35 mm) or less in thickness. The rigid polymer may be opaque,
translucent,
transparent, or a combination thereof. Top component 210 and bottom component
211
may be joined together by a process that bonds the flexible polymer to the
rigid polymer,
non-limiting examples of which include injection molding or adhesive bonding.
The
lower area 22 of handle 20 may be comprised of a rigid polymer such as
polypropylene
or ABS. The lower area 22 may be about 0.25 inches (6.35 mm) or less in
thickness.
The rigid polymer may be opaque, translucent, transparent or a combination
thereof.
Upper area 21 and/or lower area 22 of handle 20 may include support structure
25. When
included, support structure 25 if desired, may be arranged in an aesthetically
pleasing
visual manner. For example, in one non-limiting embodiment, some portion of
handle 20
could be translucent or transparent such that some portion of the support
structure 25 is
visible. Additionally or alternatively, support structure 25 if desired could
be located on
the exterior of handle 20. Additionally or alternatively, if desired an
aesthetically
pleasing visual pattern could be included on handle 20.
The upper area 21 of handle 20 may be joined to lower area 22 of handle 20 in
any number of different ways, non-limiting examples of which include utilizing
one or
more snaps and/or one or more screws to join the parts, and/or bonding the
parts together
such as by adhesive bonding or ultrasonic welding. Referring to FIG. 7, in one
non-
limiting example of the use of a snap, bottom component 211 of upper area 21
of handle
20 includes protrusion 212 which coincides with boss 220 of lower area 22 of
handle 20
so as to join upper area 21 with lower area 22.
Referring to FIGS. 1- 8, cleaning head 30 includes a top and a bottom.
Cleaning
head 30 may also include attachment structure 43 for attaching a cleaning
sheet. Though
not shown, attachment structure 43 could alternatively (or additionally) be
included with
handle 20. The top of cleaning head 30 is comprised of base 41. Base 41 may be
comprised of a rigid or flexible polymer including but not limited to
polypropylene or
ABS. Base 41 may be about 0.25 inches (6.35 mm) or less in thickness and may
be
opaque, translucent, transparent or a combination thereof. Base 41 may have a
length to
width ratio between about 1:1 to about 2:1. It is desirable that the width of
base 41 be
sufficient to provide stability of the cleaning implement 10 while in use.
CA 02601270 2007-09-10
WO 2006/110792 PCT/US2006/013587

Base 41 of cleaning head 30 may be connected to handle 20 in any number of
different ways, non-limiting examples of which include utilizing one or more
snaps
and/or one or more screws to join the parts and/or bonding the parts together
such as by
adhesive bonding or ultrasonic welding. Referring to FIG. 7, in one non-
limiting
example which displays the use of a snap, base 41 may include protrusion 412
which can
be connected to a corresponding female connection (not shown) located in the
lower area
22 of handle 20. Furthermore, screw 225 may be included to connect base 41 to
pad 51.
Referring to FIGS. 1 - 8, cleaning head 30 and/or pad 51 may include if
desired at least
one apex 413. The vertex of apex 413 forms angles 01 and 02, as shown in FIG.
1,
wherein either angle can range from about 20 to about 80 . When present,
angles 01 and
02, of cleaning head 30 may be the same as or different than angles Ol and 02,
of pad 51.
While not wishing to be limited by theory, it is believed that apex 413 can
help facilitate
cleaning by enabling a user to access hard to reach areas such as corners of
the surface
being cleaned. Furthermore, when implement 10 is used in conjunction with a
moist
cleaning sheet, apex 413 allows for enhanced delivery and penetration of the
cleaning
solution to the area being cleaned. This also allows for enhanced pinpoint
spot cleaning.
Base 41 of cleaning head 30 may include concave area 42 which when present
will typically be located near the center of base 41. Concave area 42 provides
a
convenient area for the knuckles of the user when the implement 10 is in use.
Concave
area 42 may be of any shape including but not limited to oval shaped. In one
non-
limiting example, concave area 42 has a depth of approximately 0.50 inches (13
mm), a
length of approximately 4 inches (10 cm) and a width of approximately 3 inches
(8 cm).
Cleaning implement 10 may include attachment structure 43. Attachment
structure 43 can be formed as part of cleaning implement 10 or can be formed
separately
and applied to cleaning implement 10. Attachment structure 43 may be included
with
cleaning head 30, handle 20, or a combination thereof. Referring to FIGS. 1-
8, in one
non-limiting example, base 41 of cleaning head 30 may include attachment
structure 43
for receiving and retaining a cleaning sheet. Examples of attachment structure
43 include
but are not limited to VELCRO , magnets, tabs, adhesives, hooks, grippers, and
the like.
Attachment structure 43 which may also be used with the present invention is
disclosed
in U.S. Patent Nos. 6,484,346 issued to Kingry et al. on November 26, 2002;
U.S.
6,651,290 issued to Kingry et al. on November 25, 2003; and U.S. 6,305,046
issued to
Kingry et al. on October 23, 2001.
Cleaning head 30 may also include pad 51 as shown in FIGS. 1- 8. Pad 51 can
be joined to the bottom of cleaning head 30 by any suitable joining means. For
example,
pad 51 can be joined to the bottom with one or more snaps. Additionally, pad
51 can be
CA 02601270 2007-09-10
WO 2006/110792 PCT/US2006/013587
7
adhesively joined. In another non-limiting embodiment pad 51 can be joined to
the
bottom by ultrasonic welding. If desired, pad 51 could optionally be removable
and/or
interchangeable. For instance, in one non-limiting example, pad 51 could be
interchanged with another pad, a brush, adhesive surface, some other type of
cleaning
surface, or a combination thereof.
Pad 51 may be made of a polymer such as polypropylene or ABS. If a polymer is
used, it can be opaque, translucent, transparent, or a combination thereof.
Pad 51 may
also be made from foam such as polyethylene or ethylene vinyl acetate ("EVA").
Typically the foam utilized for this purpose is a closed cell foam. While not
wishing to
be bound by theory, it is believed that the closed cell foam will tend not to
retain moisture
as readily as an open cell foam hence reducing the chances of forming mold and
mildew.
Pad 51 can be flat, convex, concave, or a combination thereof. If pad 51 is
convex or concave, the height differential would be determined by measuring
the
difference between the lowest point on pad 51 and the highest point on pad 51.
The
height differential can range from about 0 mm to about 20 mm which would be
determined by measuring the difference between the lowest point on the
outwardly facing
bottom of pad 51 and the highest point on the outwardly facing bottom pad of
51. While
not wishing to be bound by theory, it is thought that a convex surface in
contrast to a flat
surface may allow for more efficient use of a cleaning sheet thereby
maximizing delivery
of the cleaning solution to the fabric.
If comprised of foam pad 51 may have an Indentation Force Deflection ("IDF")
of
at least about 30 newtons as measured in accordance with ASTM D5672-03. While
not
wishing to be bound by theory, it is believed that an IDF of at least about 30
Newtons
will allow pad 51 to deflect less than the surface being cleaned therefore
enhancing the
effectiveness of implement 10.
If desired, all or some portion of the outwardly facing surface of pad 51 can
be
modified to increase the coefficient of friction. While not wishing to be
bound by theory,
it is thought that the increase in the coefficient of friction may enhance
contact of the
implement 10 to the surface being treated thereby facilitating soil removal
from the
treated surface. Furthernlore, when implement 10 is used in conjunction with a
cleaning
sheet, it is believed that the increase in the coefficient of friction may
assist with
minimizing slippage of the cleaning sheet from implement 10. The outwardly
facing
surface of pad 51 can be modified by texturing, TPE, soft touch paint, etc.
Referring to
FIG. 5, the outwardly facing surface of pad 51 may also include indicia 52, a
non-limiting
example of which includes an array that creates an image or pattern such as
raised and/or
recessed areas. While not wishing to be limited by theory, it is believed that
when used
CA 02601270 2007-09-10
WO 2006/110792 PCT/US2006/013587
8
in conjunction with a cleaning sheet, pad 51 which includes these indicia 52
provide a
signal to a user. One non-limiting example of a signal includes a visual
signal which can
for instance signal the status/condition of the cleaning sheet, (i.e.; provide
an indication
of the soil level of the cleaning sheet and/or when the cleaning sheet needs
to be
changed), and/or send a message to a consumer such as provide use
instructions, and/or
indicate a trade name, logo, aesthetic design, and/or some other message.
Referring to FIGS. 1- 2 and 4 - 7, implement 10 may also include angled
surface
60 on at least one end of handle 20 and/or cleaning head 30. While not wishing
to be
bound by theory, it is thought that angled surface 60 can allow for enhanced
spot
treatment/scrubbing of a fabric surface. Furthermore, when used in conjunction
with a
moist cleaning sheet, it is believed that angled surface 60 will allow for
enhanced
delivery of the cleaning solution upon contact of the cleaning sheet with the
fabric
surface. Angled surface 60 may be comprised of a foam or a rigid or flexible
polymer
non-limiting examples of which include polypropylene and/or ABS. Angled
surface 60
may be smooth. Alternatively, some portion or all of angled surface 60 may be
textured
and/or include some other type of structure which increases the coefficient of
friction of
this surface. Referring to FIG. 6, in one non-limiting embodiment, the
bottommost point
of the outwardly facing side of pad 51 and the topmost point of angled surface
60 form
angle a as shown in FIG. 6 wherein angle a may range from about 10 to about
120 ; or
from about 20 to about 110 ; or from about 40 to about 100 ; or from about
70 to
about 90 . Angled surface 60 may be flat, convex, concave, or a combination
thereof.
Kit
The cleaning implement of the present invention may be provided alone or it
may
be provided in conjunction with a cleaning sheet as a kit to clean fabrics
around the
house. The cleaning sheet may be used dry, may be moistened by the user, may
be

Self-Instructing Article of Commerce
The present invention also encompasses an article of commerce comprising the
cleaning implement and cleaning sheet kit described above. A set of
instructions may be
included in association with the kit which directs the user to follow the
method of
cleaning fabric around the house with the kit. The instructions may be in the
form of
written words, pictorials, graphic, symbols/icons, and the like, as well as
combinations
thereof. For instance, in one non-limiting embodiment, such instructions
direct the user
to attach a cleaning sheet to the implement and contact the area(s) of the
fabric to be
cleaned with the around the house fabric cleaning article. In another non-
limiting
embodiment, the user is directed to attach an apertured cleaning sheet to the
cleaning
implement such that the apertures are aligned in a direction perpendicular to
the
longitudinal axis of the handle.
Herein, "in association with", when referring to such instructions, means the
instructions are either directly printed on the implement; directly printed on
the
packaging for the implement and/or the cleaning sheet; printed on a label
attached to the
packaging for the implement and/or the cleaning sheet; or presented in a
different manner
including, but not limited to, a brochure, print advertisement, electronic
advertisement,
broadcast or internet advertisements; and/or other media, so as to communicate
the set of
instructions to a consumer of the implement and/or the cleaning sheet.
Method of Use
The present invention also includes a method for treating household fabric-
based
materials with the implement of the present invention in conjunction with a
disposable
cleaning cloth/cleaning sheet. This includes attaching a cleaning sheet to the
implement
of the present invention; contacting the cleaning sheet portion of the
implement to the
surface to be cleaned so as to transfer the soil from the surface being
cleaned to the
cleaning sheet. In another non-limiting embodiment wherein an apertured
cleaning sheet
is utilized, the cleaning sheet may be attached to the cleaning implement such
that the
apertures are aligned in a direction perpendicular to the longitudinal axis of
the handle of
the cleaning implement. In another non-limiting embodiment, the method of use

include one or more of the following steps: providing a package containing one
or more
cleaning sheets, removing a cleaning sheet from the package, wiping down the
item to be
cleaned with the cleaning sheet, disposing of the cleaning sheet after use
such as tossing
the used cleaning sheet into the garbage. In another non-limiting embodiment,
similar to
the above, after the cleaning sheet is removed from the package it may be
attached to the
cleaning implement of the present invention. For instance, in one-non-limiting
example,
the cleaning sheet is removed from the package and spread out vertically. The
bottom of
the cleaning implement is placed approximately in the center of the cleaning
sheet. The
cleaning sheet is then attached to the cleaning implement. For instance, in
one non-
