MULTIPACK FOR CUPS AND POTS
This invention relates to a multipack that includes multiple containers positioned within two adjacent rows of apertures formed in a sheet having an integral handle, resulting in a package of two or more containers and a flexible handle extending therefrom.
This Application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/978,314, filed 7 Oct. 2007.
BACKGROUND OF THE INVENTION1. Field of the Invention
This invention relates to a flexible multipack with an integral handle for unitizing a plurality of containers, particularly cups or pots.
2. Description of Prior Art
Conventional multipacks are generally paperboard sleeves, cartons or boxes into which yogurt cups, cat food cans, tuna cans and similar such containers may be inserted to unitize a group of two or more such containers.
SUMMARY OF THE INVENTIONAccording to a preferred embodiment of this invention, a multipack preferably includes two layers of a generally planar flexible sheet having a plurality of apertures. An integral handle is preferably formed along at least one side of the multipack.
Accordingly, multiple containers may be placed within the apertures of the multipack and the sheet is folded to position an end portion of each container against an end portion of an adjacent container. At least one edge of the sheet may then be sealed or otherwise closed to enclose the containers within the multipack. The resulting package may be displayed and carried using the integral handle and preferably clearly displays the enclosed containers.
Further, the resulting multipack may include a geometry of containers that permit a freestanding display of each multipack in the manner of an easel such that graphics and/or product may face the consumer when the multipack is properly faced on a shelf.
The above-mentioned and other features and objects of this invention will be better understood from the following detailed description taken in conjunction with the drawings wherein:
Containers 80 are preferably, though not necessarily as shown in
Multipack 10 unitizes one or more containers 80 to create package 90, such as package 90 shown in
According to a preferred embodiment of this invention, sheet 15 used to form multipack 10 is extruded from a polymer composition which includes a high pressure low density polyethylene polymer. The composition provides the multipack 10 with improved recovery after stretch, improved elongation and strength at break, and improved resistance to tearing when the multipack is notched or scratched. The low density polyethylene polymer may have a density of about 0.910-0.950, grams/cm3, suitably about 0.920-0.940 grams/cm3, desirably about 0.925-0.935 grams/cm3. In other words, the term “low density polyethylene polymer” includes polyethylene polymers commonly considered as having medium density, as well as polyethylene polymers commonly considered as having low density.
Alternatively, sheet 15 may be formed of a higher density plastic, paperboard, or any similar material having desirable strength and flexibility properties.
According to a preferred embodiment of this invention, sheet 15 is preferably cut, using means known to those skilled in the art, such as a stamping die, to form a perimeter of multipack 10. Multipack 10 is preferably formed with a plurality of apertures 40 arranged in two parallel rows extending longitudinally across sheet 15. Each aperture 40 preferably accommodates a container 80 resulting in two parallel rows of containers 80. Apertures 40 are preferably configured to accommodate a perimeter of container 80, as such
Foldline 30 preferably extends between the two parallel rows of apertures 40. Foldline 30 permits the two parallel rows of containers to be folded onto each other, preferably such that an end portion or lid of each container abuts an adjacent end portion of each transversely adjacent container.
Following folding along foldline 30, the two layers of sheet 15 may additionally be joined across a top and bottom of multipack 10 using lower weld 45 and/or upper weld 50, as best shown in
As a result of the preferred placement of foldline 30 and/or one or more welds 45, 50 along edges of sheet 15, multipack 10 is formed into two “halves” that are foldable onto each other. Containers 80 are preferably loaded into apertures 40 of multipack 10 such as shown in
Containers 80 may be dropped into apertures 40 and snugly engaged with a taper, a chime, a lid and/or an alternative physical feature of the container 80. Alternatively, sheet 15 may be stretchingly engaged with containers 80 by placement of container 80 within a respective undersized aperture 80 thereby creating a snug, engaged fit between container 80 and multipack 10.
According to one preferred embodiment of multipack 10, containers 80 are inserted into apertures 40 so that lids are upwardly facing prior to folding sheet 15 across foldline 30. As a result, following folding, multipack 10 is arranged so that a bottom end of container 80 protrudes and is visible from multipack 10. As a result, it may be preferable to include decorative markings and/or container information on the bottom end of container 80 to provide effective display of multipack 10 and the corresponding unitized containers 80.
As shown in
Handle 60 may comprise finger aperture 65 positioned within an extension of at least one layer of plastic sheet 15, such as shown in
As described, multipack 10 is preferably arranged in such a geometry so as to permit a freestanding package suitable for placement on a store shelf or hanging from a peghook style display. Because of the arrangement of the adjacent containers 80, whereby an end of each container, such as a lid, abuts an end of an adjacent container, multipack 10 is configured to freely stand on a surface thereby permitting access to the upwardly extending handle 60 and permitting prominent display of portions of the outwardly extending containers 80.
According to a preferred embodiment of this invention, at least one line of weakness 70 may extend across at least one layer of sheet 15 of multipack 10. For example, two spaced and generally parallel lines of weakness 70, forming a “zipper,” may extend across an upper portion of multipack 10. A pull tab may be positioned on one or both sides of the zipper to facilitate pulling and opening.
Line of weakness 70 may comprise perforations, serrations, slits, reduced thickness or combination thereof formed in sheet 15 and are preferably tearable or frangible to permit separation of sheet 15 along a defined line. Following such separation, containers 80 are preferably readily accessible within package 90.
According to embodiments of the invention best shown in
According to a preferred embodiment of this invention, multipack 10 is formed of generally transparent plastic sheet 15. However other materials and compositions of sheet 15 may be used. For instance, one layer of sheet 15 may be formed of a generally opaque pigmented material and another layer of sheet 15 may be transparent, tinted, printed or similarly configured to best display the included containers 80 within package 90. Any other similar configurations may be combined that result in an aesthetically pleasing and/or functional package 90.
While in the foregoing specification this invention has been described in relation to certain preferred embodiments thereof, and many details have been set forth for purpose of illustration, it will be apparent to those skilled in the art that multipack 10 and the related method of manufacture are susceptible to additional embodiments and that certain of the details described herein can be varied considerably without departing from the basic principles of the invention.
