BLISTER PACKAGE ASSEMBLY FOR CONFECTIONARY PRODUCTS
FIELD OF INVENTION
The present invention relates generally to consumer product
packaging. More particularly, the present invention relates to packaging of
confectionary, pharmaceutical products, or the like.
BACKGROUND OF THE INVENTION
The packaging for consumable products is very important to the
storage of the product. Frequently, the packaging attempts to visually convey
indicia about the type of product, the taste of the product or the purpose of
the
product. For example, some packages for consumer products, such as gum
or candy, frequently include indicia on the package indicating the type of
tasting product available in the package. Once a consumer identifies the type
or product from the package, the consumer typically chooses a product based
solely on the packaging indicia.

Various types of blister package assemblies are known in the art. For
example, in U.S. Pat. No. 5,358,118 to Thompson et al., a stepped-edge
blister pack for containing and dispensing units of doses of medication such
as capsules, tablets, caplets or fast-dissolving dosage forms is disclosed. In
U.S. Pat. No. 6,092,660 to Rune et al., a blister pack is disclosed that
comprises at least one blister pack with individually openable blisters
including a number of blisters containing placebo (placebo blisters), and a
number of blisters containing an active pharmaceutical drug.
Although today's blister packages adequately support products
contained therein, there are some disadvantages. For example, if it is felt
that
an entire portion of the product may be consumed in one sitting, such as in
the case of a candy bar, the manufacturer may wish to provide a once only
usable package to store the product, rather than a reusable package.
Furthermore, there are also practical facets to packaging consumable
products, namely, ease of access to the products stored in the packaging,
flexibility of the packaging once pieces of the product are removed, and
providing a reusable package.
It is therefore desirable to provide a product package assembly that
supports one or more products in a reusable assembly that is not costly and is
robust enough to support less than all the products that are removed from the
package. Furthermore, it is desirable to provide a packaging assembly that is
2
CA 02661761 2009-02-23
WO 2008/027437 PCT/US2007/019008
flexible and yet robust enough to support one or more various types of
products once some are consumed.
SUMMARY OF THE INVENTION
A packaging assembly supports and dispenses a plurality of retail
products, such as confectionary products. The assembly includes a housing
having a plurality of package sleeves that are removably attached to one
another. A blister tray attachment is slidably insertable into one or more of
the
package sleeves.
For example, in one aspect of the invention, a method of providing a
package assembly for consumable products includes forming a housing
including a plurality of sleeves, removably attaching the plurality of sleeves
to
one another using an adhesive, and providing a blister tray slidably
insertable
into one or more of the sleeves, the blister tray supporting consumable
products. The method also can include attaching the plurality of sleeves to
one another using an adhesive.
In one preferred embodiment, the method includes forming at least one
cut score on an outer surface of one of the plurality of sleeves and applying
the adhesive to the at least one cut score. Preferably, the method further
includes forming the cut score by cutting a fifty percent cut score through a
top layer of one of the plurality of sleeves.

In one preferred embodiment, the method includes attaching the
plurality of sleeves to the housing at a detachable perforated line so as to
allow the removal of one of the plurality of sleeves. The method can also
include folding ends of a flat piece of paperboard material toward one another
and attaching at least one surface of the ends to the housing.
In another aspect, a blister package assembly for consumable products
includes a housing including a plurality of sleeves, a blister tray slidably
insertable into at least one of the plurality of sleeves, the blister tray
supporting consumable products, wherein the plurality of sleeves are
removably attached to one another using an adhesive, the adhesive applied
to an outer surface of one of the plurality of sleeves.
In one preferred embodiment, the adhesive is applied to a cut score
formed on the outer surface. Preferably, the cut score is a fifty percent cut
score formed on the outer surface. In another preferred embodiment, the
package assembly includes a plurality of cut scores formed on the outer
surface, each of the plurality of cut scores including adhesive.
Preferably, the plurality of sleeves are attached to the housing at a
detachable perforated line so as to allow the removal of one of the plurality
of
sleeves.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention provides a packaging assembly for supporting
and dispensing retail products. The products are consumable or confectionery
5
CA 02661761 2009-02-23
WO 2008/027437 PCT/US2007/019008
products. The products include any type of consumable or confectionery
products such as gum or candy. The products can alternatively be any other
type of consumable products. For instance, the products can be gum or candy
or other type of medical or consumable product.
FIG. 1 illustrates a perspective view of a first embodiment of a package
assembly 10 according to the present invention. FIG. 2 illustrates a top view
of the package assembly 10 of FIG. 1. Although the package assembly 10
shown in the drawings is designed to preferably be used to support and
dispense confectionery products, e.g., gum, the assembly also can be used to
support and dispense other products, e.g., pharmaceuticals.
As shown in FIGS. 1 and 2, the package assembly 10 of the present
invention includes a plurality of sleeves 17, 19 that are removably attached
to
a housing 12. In one preferred embodiment, for example, the plurality of
sleeves 17, 19 are uniform in shape and have a generally rectangular form.
The assembly also includes one or more packages or blister trays 14, 15 that
are removable from and reinsertable into the sleeves 17, 19. For example, as
shown by the arrows 6, 8 in FIGS. 1 and 2, a consumer may slidably remove
blister trays 14, 15 from the sleeves 17, 19 and slidably reinsert the blister
trays 14, 15 into the sleeves 17, 19 as desired.
Preferably, the blister trays 14, 15 of the present invention are made
primarily from plastic and/or plastic or metal foils. As shown in FIG. 1, each
6
CA 02661761 2009-02-23
WO 2008/027437 PCT/US2007/019008
tray 14, 15 includes a plurality of compartments 18A-D, 18E-H, respectively,
of generally equal dimensions that generally extend outwardly from each tray
14, 15. The trays 14, 15 are dimensioned to press-fit against walls of the
sleeves 17, 18 upon insertion of the trays 14, 15 into the sleeves 17, 18. In
one preferred embodiment, the center of each blister tray 14, 15 includes a
hinge 9 allowing each tray to be folded onto itself and to be stacked. Once
stacked, the two blister trays 14, 15 may be slidably removed and inserted
into the sleeves, resulting in shorter and wider sleeves. The compartments
18A-H generally hold or store a single product 20A-H, however, in other
embodiments, compartment dimensions may be varied and can store multiple
and varied products. In one preferred embodiment, the compartments 18A-H
are made from plastic that is clear so that a consumer can see the products
stored therein. As shown in FIGS. 1 and 2, in a preferred embodiment, the
compartments 18A-D of tray 14 and compartments 18E-H of tray 15 are
arranged in a series of four (4) longitudinally spaced compartments each,
however, each of the trays 14,15 may be adapted to have any number of
compartments in various configurations.
As shown in FIG. 1 and 2, in one preferred embodiment, the blister
trays 14, 15 are configured to include a slot 22 that may aid the consumer in
slidably inserting and removing the blister trays from the sleeves 17, 19. The
slot 22 also may be used to facilitate mounting of the package assembly on a
product display module. For example, the slot 22 is configured to receive a
product display bracket extending from a product display module.

WO 2008/027437 PCT/US2007/019008
The sleeves 17, 19 of the present invention are made from single or
multiple pieces of cardboard or other suitable material and are shaped to
support the blister trays 14, 15. The material for the sleeves 17, 19 is
preferably chosen to be relatively inexpensive and may in certain
embodiments be biodegradable or recyclable. For example, biodegradable
paperboard may be used to form the sleeves 17, 19. Of course, it will be
appreciated by one skilled in the art that other materials, such as unbleached
board as well as polymeric material, may be used to form the sleeves 17, 19
depending on the desired appearance of the assembly 10. If paperboard is
used, preferably, the paperboard is coated on at least one side with a
conventional coating selected for compatibility with a printing method and
board composition chosen for the assembly 10.
Preferably, the sleeves 17, 19 are formed by folding the housing 12 so
that after folding, the coated side of the housing would become the external
surface of each sleeve 17,19. This allows for indicia concerning the product
contents of the assembly 10 to be viewed without removing the package trays
14, 15 from the sleeves 17,19. Details with respect to folding the housing 12
to form the sleeves 17, 19 are discussed in connection with FIGS. 3 and 6 of
the application. It should be noted, however, that the sleeves 17,19 of the
present invention are not limited to being formed by folding the housing 12.
For example, in one preferred embodiment, the sleeves 17, 19 are formed
separately from the housing 12 and are made from paperboard. Once the
8
CA 02661761 2009-02-23
WO 2008/027437 PCT/US2007/019008
sleeves 17,19 are formed, the sleeves 17,19 are attached to a flat piece of
paperboard using an adhesive, such as glue, to.form the housing 12.
As shown in FIGS. 1 and 2, each of the sleeves 17, 19 includes
opposing side walls 21, 23 and 24, 25, top walls 28, 29 and bottom walls 30,
31, respectively. Preferably, the sidewalls 21,23, 24,25, top walls 28, 29 and
bottom walls 30,31 define front open ends or front openings 33, 35 and back
open ends or back openings 26, 27 of each sleeve 17, 19, respectively. Of
course, it will be appreciated by one skilled in the art that the sleeves of
the
present invention are not limited to having both front openings and back
openings. For example, in one preferred embodiment, the sleeves include
front openings and back walls instead of back openings. In another preferred
embodiment, the openings of sleeves are configured diagonally to one
another, resulting in each sleeve having either a front wall or a back wall
and
a back opening or front opening, respectively. Further, as shown in the FIG. 1
and 2 example, the top walls 28, 29 and bottom walls 30, 31 of each sleeve
17, 19 may include recesses 34, 37 that may aid the consumer in slidably
inserting and removing the package trays 14,15 and/or are for aesthetic
purposes.
Referring now to FIG. 3, a plan view of the housing 12 of FIG. 1 is
shown. The housing 12 of the present invention is preferably a paper product
made in a flat piece. For example, in one preferred embodiment, the housing
12 is made from a single flat piece of paperboard material. As shown in FIG.
9
CA 02661761 2009-02-23
WO 2008/027437 PCT/US2007/019008
3, the housing 2 includes a series of wall flaps 118, 120, 122, 124, 126, 128,
130 and 132, folds 100, 102, 104, 106, 108, 110, 112, and 114, and
attachment flaps 116, 134, wherein the housing folds together and forms the
sleeves 17, 19.
For example, as shown in FIG. 3, a surface of the attachment flaps
116, 134 is covered with an adhesive, such as glue, such that, by folding the
attachment flaps 116, 134 over and toward one another, sleeves having an
approximately equal dimension to one another are achieved. As shown in
FIGS 1, 2 and 3, the attachment flaps 116, 134 are folded over approximately
one-half (1/2) the diameter of the housing 12 and form the sleeves 17,19 by
contact and adhesion of the attachment flaps to wall flaps 124, 126. In
addition, in some preferred embodiments, the outer surface of one of the wall
flaps 118 includes a glue print side 32 that includes an adhesive, such as
glue, that as the sleeves 17, 19 are positioned in juxtaposition with one
another, the glue print side 32 contacts and loosely couples sidewalls 23, 24
of the sleeves 17, 19 together.
For example, in one preferred embodiment, as shown in FIG. 3, the
glue print side 32 is formed from a fifty percent (50%) cut score through the
top layer for a clean release of the sleeves 17, 19 that results in non-
tearing of
the sleeves 17, 19 upon separation. In some preferred embodiments having
longer sleeves, a plurality of release cut-scores are provided on the outer
CA 02661761 2009-02-23
WO 2008/027437 PCT/US2007/019008
surface of one of the wall flaps 118 that can contact and loosely couple
sidewalls of sleeves.
Of course, it will be appreciated by one skilled in the art that the points
of adhesion on the flaps may be varied and that various sleeve diameters may
be achieved to support varying tray diameters. For example, as shown in
FIG. 7, the sleeves 17, 19 may be positioned spaced apart from one another
at a predetermined distance 11. In addition, it will be appreciated by one
skilled in the art that other techniques may be used to secure attachment
flaps
116, 134 to wall flaps 124,126. For example, in one preferred embodiment,
attachment flaps 116, 134 and wall flaps 124, 126 may be secured together
as interlocking flaps. Further, when the housing 12 is made from polymeric
material, such as plastic, the desirable shape of the sleeves may be made via
a process of molds or other suitable method of mass producing plastic.
As shown in FIGS. 1, 2, and 3, a center of the housing 12 is provided
as a hinge 38 that allows the sleeves 17, 19 to be flexed about each other.
Preferably, the hinge 38 allows the sleeves 17, 19 to be pulled back from one
another and stacked, resulting in an outer surface of a top wall of one of the
sleeves contacting an outer surface of a bottom wall of another sleeve.
Several benefits may be derived by this feature. For example, by providing
the flexible hinge 38 as part of the housing 12, formed sleeves 17, 19 may be
flexed toward and away from one another and thereby reduce the overall
dimensions needed to store the product assembly 10. The hinge 38 of the
11
CA 02661761 2009-02-23
WO 2008/027437 PCT/US2007/019008
housing 12 may be constructed as a detachable perforated line allowing the
sleeves 17, 19 to be independently separated from the housing 12 to further
reduce the space necessary for storing the product especially after partial
use
of the product. The perforated line also allows the housing 12 to be split
into
two pieces, thus allowing each sleeve to be used independently.
Referring now to FIGS. 4, 5 and 6, a second embodiment of a package
assembly 40 according to the present invention is disclosed. In particular,
FIG. 4 illustrates a perspective view of the package assembly 40 and FIG. 5
illustrates a top view of the assembly 40. As shown in FIGS. 4 and 5, the
package assembly 40 includes one or more package or blister trays 44, 45
that are removable and reinsertable, as indicated by arrows 51, 53,
respectively, into sleeves 47, 49 of a housing 42. In the preferred
embodiment, the sleeves 47, 49 have a generally square form and are of
generally uniform shape.
As shown in FIGS. 4 and 5, each of the package trays 44, 45 includes
four (4) compartments 48A-D, 48E-H arranged in a side-by-side 2x2
configuration that generally extend outward from each tray 44, 45 and are
configured to press-fit against walls of the sleeve 47, 49. The compartments
48A-H, like the compartments 18A-H described above, may be made of clear
plastic so that the consumer can see the products 50A-H stored therein.
12
CA 02661761 2009-02-23
WO 2008/027437 PCT/US2007/019008
Similar to the blister trays 14, 15 described above, the blister trays 44,
45 of the second embodiment are configured to include a slot 52 that may aid
the consumer in removing and inserting the blister trays 44, 45 into the
sleeves 47, 49. The slot 52 similarly may be adapted to receive a product
display bracket to display the assembly 40 from a product display module.
Similar to the sleeves 17, 19 described above, the sleeves 47, 49 of
the second embodiment are made from single or multiple pieces of cardboard
or other suitable material. Preferably, the material chosen is relatively
inexpensive and may, as described previously, in certain embodiments, be
biodegradable or recyclable. Preferably, if paperboard is used to form the
sleeves 47, 49, the paperboard is coated on at least one side with a
conventional coating selected for compatibility with a printing method and
board composition chosen for the assembly 40.
The sleeves 47, 49 are also formed by folding the housing 42 so that
after folding, the coated side of the housing 42 becomes the external surface
of each sleeve 47, 49. By using this technique, indicia concerning the product
contents of the assembly 40 may be viewed without removing the package
trays 44, 45 from the sleeves 47, 49.
As shown in FIGS. 4 and 5, each of the sleeves 47, 49 includes
opposing side walls 54, 55 and 56, 57, top walls 58, 59 and bottom walls
60,62, respectively. Preferably, the sidewalls 54, 55, 56, 57, top walls 58,
59
13
CA 02661761 2009-02-23
WO 2008/027437 PCT/US2007/019008
and bottom walls 60, 62 define front openings 61, 63 and back openings 66,
64 of each sleeve 47, 49, respectively.
Referring now to FIG. 6, a plan view of the housing 42 of FIG. 4 is
shown. As described previously, the housing 42 of the present invention is
preferably a paper product made in a flat piece. Similar to the housing 12
described above, the housing 42 of the package assembly 40 also includes a
series of wall flaps 202, 204, 206, 208, 210, 212, 214 and 216, folds 220,
222,
224, 226, 232, 234, 236 and 238, and attachment flaps 200, 218 that are
dimensioned such that when the housing 42 folds together, a desired shape
for the sleeves 47, 49 is obtained.
Similar to the attachment flaps 116, 134 described above, as shown in
FIG. 6, a surface of the attachment flaps 200, 218 is covered with an
adhesive, such as glue, such that, by folding the attachment flaps 200, 218
over and toward one another, sleeves 47,49 having an approximately equal
dimension are achieved. For example, to form the two (2) relatively square
shaped sleeves 47, 49 shown in FIGS. 4 and 5, the attachment flaps 200, 218
are folded over approximately one-half (1/2) the diameter of the housing 42
and form the sleeves 47, 49 by contact and adhesion of the attachment flaps
200, 218 to wall flaps 208, 210, respectively. The sleeves 47, 49 are
positioned spaced apart from one another at a predetermined distance. In
addition, the outer surface of one of the wall flaps 202 can include a print
glue
side 240 that includes an adhesive, such as glue, that as the sleeves 47, 49
14
CA 02661761 2009-02-23
WO 2008/027437 PCT/US2007/019008
are positioned in juxtaposition with one another; contacts and loosely couples
sidewalls 55, 56 of the sleeves 47, 49 together. Preferably, the print glue
side 240 is formed similarly as discussed in connection with the glue print
side
32 of FIG. 3.
As shown in FIGS. 4, 5 and 6, preferably, a center of the housing 42
includes a hinge 230 that allows the sleeves 47, 49 to be flexed about each
other. Similar to the housing 12 described above, the hinge 230 may be
formed as a detachable perforated line allowing the sleeves 47, 49 to be
independently separated from the housing 42 regardless of product in the
sleeves 47, 49.
It will be appreciated by one skilled in the art that the current invention
is not limited to a housing including only two sleeves nor a single hinge, but
can include any number of sleeves and multiple hinges or detached
perforated lines. For example, referring now to FIG. 8, in one preferred
embodiment, a package assembly 300 is provided that includes three sleeves
304, 306 and 308 that are removably attached via detachable perforation lines
316 to a housing 302. The assembly 300 also includes three blister trays 310,
312 and 314 that are removable from and reinsertable into the sleeves 304,
306 and 308, as discussed in connection with FIGS. 1-2 and 4-5. The
housing 302, sleeves 304, 306, 308 and hinges 302 are formed similarly as
discussed in connections with FIGS. 1-7.
