Abstract
This invention relates to a package of a plurality of containers unitized with a flexible carrier. The carrier is constructed from a plastic planar sheet having a plurality of container receiving openings arranged in longitudinal rows and transverse ranks. A panel extends from a longitudinal edge of the planar sheet that is arranged to either remain flat and tight with respect to the package or, alternatively, follow an external contour of the package.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a carrier for unitizing containers having a plurality of container receiving openings configured to allow an integral panel to remain in one of a flat and tight position or a contoured and tight position with respect to the containers.
2. Description of Prior Art
Conventional container carriers are often used to unitize a plurality of similarly sized containers, such as cans, bottles, jars and boxes, although other packages or containers may be unitized. Plastic ring carriers and box carriers are two such conventional container carriers.
The plastic ring carrier produces a unitized package for containers using little material. However, when used alone has little or no advertising or promotional printing space. Conversely, the box carrier generally has a relatively large amount of area for promotional graphics. Disadvantageously, the box carrier requires a relatively large amount of material, permits bottles to fall out if it is not maintained in an upright position, and usually shrouds much of the actual containers. Therefore, there is a need for a package that incorporates the stability and economy of a ring carrier and the promotional area of a box carrier.
SUMMARY OF THE INVENTION
It is one object of this invention to provide a container carrier that is rim-applied to containers and provides a panel for merchandising information.
It is still another object of this invention to provide a container carrier which restricts lateral and vertical movement of the containers with respect to one another.
It is yet another object of this invention to provide a container carrier that incorporates the stability and economy of a ring carrier and the promotional area of a box carrier.
It is yet another object of this invention to provide a panel that can support the weight of a package of containers if inadvertently used as a handle for the package.
It is still another object of one preferred embodiment of this invention to provide a container carrier that maintains a panel in a flat and tight configuration with respect to the unitized containers.
It is yet another object of another preferred embodiment of this invention to provide a panel on a container carrier that does not protrude from a package of containers and instead follows an external contour of the package.
A carrier according to this invention carries a plurality of containers such as cans. The carrier comprises a planar, preferably plastic., sheet formed with a plurality of container receiving openings. The container receiving openings are formed in longitudinal rows and transverse ranks.
According to one preferred embodiment of this invention, the containers are positioned in each container receiving opening to form a package having a panel that is flat, tight and parallel with respect to the containers and prominent with respect to the package. Such a configuration of the panel results in a package of containers having a prominent display area or “billboard” for advertising, information, graphics and other marketing material.
According to another preferred embodiment of this invention, the containers are positioned in each container receiving opening to form a package having a contour panel that follows an external contour of the package. Such a configuration of the contour panel results in a package of containers having prominent display area without the contour panel protruding or otherwise interfering with adjacent packages.

DESCRIPTION OF PREFERRED EMBODIMENTS
FIGS. 1-10
show carrier
10
for carrying a plurality of containers
13
. Containers
13
shown in
FIGS. 2 and 9
are preferably cans. Although cans are shown in
FIGS. 2 and 9
, bottles or any other commonly unitized container
13
may be used with carrier
10
according to this invention. Containers
13
are preferably like-sized within a single carrier
10
.
Carrier
10
unitizes a plurality of containers
13
to create package
11
, such as package
11
shown in
FIGS. 2 and 9
. Carrier
10
comprises planar sheet
15
preferably constructed from a flexible, resilient material such as plastic. In one preferred embodiment of this invention, planar sheet
15
is made from low density polyethylene. Planar sheet
15
preferably comprises two transverse edges
30
and two longitudinal edges
25
.
Planar sheet
15
of material is preferably cut, using means known to those skilled in the art, such as a stamping die, to form a plurality of container receiving openings
20
in planar sheet
15
. Except as otherwise described, container receiving openings
20
are preferably formed in a generally triangular shape having rounded corners. Preferably, six or more container receiving openings
20
are formed in planar sheet
15
in longitudinal rows and transverse ranks. Preferably, container receiving openings
20
are configured in two rows of three ranks or in two rows of four ranks. Planar sheet
15
may include other configurations of container receiving openings
20
depending on the size of package
11
desired. As shown in
FIGS. 1
,
2
and
5
-
10
, in one preferred embodiment of this invention, carrier
10
comprises sheet
15
having six container receiving openings
20
. As shown in
FIG. 4
, carrier
10
comprises sheet
15
having eight or more container receiving openings
20
.
FIGS. 1-4
show carrier
10
and package
1
wherein panel
35
is formed to align in a generally flat position relative to package
1
. Such a panel configuration results in a large, visible and unobstructed billboard area on a side of package
1
.
FIGS. 5-10
show carrier
10
and package
1
wherein panel
35
is formed to follow external contours of containers
13
within package
1
. Such a panel configuration results in a large billboard area on a side of package
1
that does not protrude from package
1
thus reducing the likelihood of snagging or interfering with adjacent packages
1
.
As shown in one preferred embodiment of this invention in
FIGS. 1-4
, container receiving openings
20
preferably include corner container receiving openings
22
and center container receiving opening
23
. Container receiving openings
20
are preferably longer in a longitudinal direction than wide in a transverse direction.
Comer container receiving openings
22
are located at an intersection between an outermost row of the longitudinal rows and an outermost rank of the transverse ranks. Each carrier
10
includes four corner container receiving openings
22
located at each of four corners of the generally rectangular planar sheet
15
. Comer container receiving openings
22
preferably have a reduced longitudinal length relative to container receiving openings
20
not positioned in corners of planar sheet
15
. According to one preferred embodiment of this invention shown in
FIG. 1
, corner container receiving openings
22
include a corner at an extremity of planar sheet
15
having a larger radius than the remaining corners in container receiving openings
20
. In addition, as shown in
FIG. 4
, corner container receiving opening
22
may include a generally straight edge along transverse edge
30
of planar sheet
15
.
According to one preferred embodiment of this invention, corner container receiving opening
22
is asymmetrical about apex
27
of corner container receiving opening
22
. Preferably, corner container receiving openings
22
are shortened on a side of apex
27
closest to the outward extremity of planar sheet
15
. Therefore, a corner radius of each corner container receiving opening
22
at the four outward extremities of planar sheet
15
is larger than the radii of the remaining corners of container receiving openings
20
.
According to one preferred embodiment of this invention shown in
FIGS. 1 and 2
, center container receiving opening
23
of the plurality of container receiving openings
20
is located between corner container receiving openings
22
. Center container receiving opening
23
is positioned in planar sheet
15
adjacent an approximate center of longitudinal edge
25
.
In part because four corner container receiving openings
22
of the plurality of container receiving openings
20
each have a shortened longitudinal length, carrier
10
preferably has a non-uniform pitch. Pitch is a dimension between a center point of adjacent container receiving openings
20
in the longitudinal rows. The pitch is traditionally important because that dimension must be maintained for conventional applicating equipment used to apply carrier
10
onto containers
13
. A non-uniform pitch between longitudinally adjacent container receiving openings
20
results in non-uniform stretching of carrier
10
during application to containers
13
.
In one preferred embodiment of this invention, panel
35
is integrally formed with sheet
15
and extends from longitudinal edge
25
of sheet
15
. Panel
35
preferably has an overall longitudinal panel length approximately equal to an overall length of longitudinal edge
25
. Panel
35
preferably accommodates, on one or both sides, UPC and proof of purchase labels, graphics, and promotional and/or other information related to contents and/or ingredients of package
11
. Panel
35
is preferably generally continuous and unbroken, without cutouts or apertures, throughout its defined area.
Panel
35
preferably extends outward from longitudinal edge
25
of sheet
15
. According to one preferred embodiment of this invention, two end straps
40
connect panel
35
to longitudinal edge
25
of planar sheet
15
. Specifically, each end strap
40
connects panel
35
with a corner of longitudinal edge
25
of planar sheet
15
. End straps
40
are preferably narrow and positioned at an extremity of the corner to influence wrap around of carrier
10
with respect to containers
13
.
In addition, center strap
45
connects panel
35
with an approximate center of longitudinal edge
25
of planar sheet
15
. Center container receiving opening
23
of the plurality of container receiving openings is positioned
20
in planar sheet
15
directly adjacent center strap
45
. Planar sheet
15
immediately adjacent center container receiving opening
23
includes depression
50
that extends toward center strap
45
.
End straps
40
and center strap
45
are preferably formed of sufficient size and shape to form a solid connection with planar sheet
15
. End straps
40
and center strap
45
additionally assist in maintaining panel
35
in a flat position with respect to package
11
to increase visibility and promotional area of carrier
10
. A width of center strap
45
is preferably optimized to maintain such a flat position. Preferably, center strap
45
is wider than end straps
40
.
As shown in
FIGS. 1
,
2
and
4
, panel
35
is preferably tapered along transverse panel edges
37
. Panel
35
preferably extends longitudinally for a length approximately equal to an entire longitudinal length of planar sheet
15
. Panel preferably additionally extends in a transverse direction for a height approximately equal to a height of container
13
.
As shown in
FIGS. 2 and 3
, container
13
is positioned in each container receiving opening
20
to form package
11
. According to one preferred embodiment of this invention, panel
35
is preferably flat and parallel with respect to containers
13
and prominent with respect to package
11
. If panel
35
is curled or folded in a perpendicular position with respect to package
11
, then advertising or other material positioned on panel will not be legible to a consumer. In addition, panel
35
that protrudes with respect to package
11
will create difficulties in packaging, handling and stacking packages
11
because of interference between panels
35
of adjacent packages
11
and between panel
35
and packaging equipment.
Several of the above described features of carrier
10
facilitate a flat and prominent panel
35
with respect to package
11
. For example, the generally straight edges formed by portions of container receiving openings
20
adjacent longitudinal edge
25
urges panel
35
into a generally flat position with respect to containers
13
in package
11
. In addition, the non-uniform pitch between longitudinally adjacent container receiving openings
20
also aids in the relative flatness of panel
35
with respect to package
11
because of non-uniform stretching of carrier
10
during application to containers
13
.
The attachment points at end straps
40
and center strap
45
also create a flat panel
35
with respect to package
11
. A relatively narrow dimension of end strap
40
and the position of end strap
40
at each extremity of package
11
is important for reducing bunching and curling of panel
35
by helping to wrap panel
35
slightly around containers
13
at the ends of package
11
. The result of a tight unitized block of containers
13
is a flat panel
35
with respect to package
11
.
Depression
50
in planar sheet
15
adjacent center container receiving opening
23
also creates a tighter unitized block of containers
13
within package
11
. Depression
50
also assists carrier
10
in retaining containers
13
underneath each respective chime.
As shown in a preferred embodiment of this invention in
FIGS. 5-10
, carrier
10
comprises planar sheet
15
of a plastic material as discussed above. A plurality of generally triangular container receiving openings
20
are preferably arranged in planar sheet
15
in two longitudinal rows.
A plurality of diamond-shaped openings
65
are arranged in a longitudinal row along a center of planar sheet
15
between the two longitudinal rows of container receiving openings
20
. As shown in
FIGS. 5-10
, diamond-shaped openings
65
are preferably positioned so that a single diamond-shaped opening
65
is positioned central to four container receiving openings
20
.
Contour panel
70
extends from longitudinal edge
25
of planar sheet
15
. Contour panel
70
preferably comprises a panel width less than a length of longitudinal edge
25
of planar sheet
15
. Contour panel
70
additionally comprises a height preferably less than half a transverse width of planar sheet
15
.
A plurality of panel straps
75
preferably extend from longitudinal edge
25
to connect contour panel
70
with planar sheet
15
. According to one preferred embodiment of this invention, four panel straps
75
extend from longitudinal edge
25
of planar sheet
15
to connect contour panel
70
. Two panel straps
75
preferably extend from a center portion of longitudinal edge
25
of planar sheet
15
and two panel straps
75
preferably extend from outer portions of longitudinal edge
25
of planar sheet
15
.
According to a preferred embodiment of this invention, each panel strap
75
extending from an outer portion of longitudinal edge
25
extends from an attachment point at, or inside, a transverse center line of outer container receiving openings
20
. These attachment points, shown in
FIGS. 9 and 10
, urge contour panel
70
into contoured engagement with containers
13
in package
11
. The remaining two panel straps
75
preferably extend from a portion of planar sheet
15
immediately adjacent a center container receiving opening
20
.
According to a preferred embodiment of this invention shown in FIG.
5
, an additional contour panel
70
extends from longitudinal edge
25
of planar sheet
15
. As shown in
FIG. 5
, each contour panel
70
extends from common longitudinal edge
25
and each is connected with respect to planar sheet
15
with two panel straps
75
.
According to another preferred embodiment of this invention, shown in
FIGS. 7 and 8
, contour panel
70
further comprises center cutout
80
. Center cutout
80
assists contour panel with adhering to contour of package
11
in an assembled carrier
10
.
In package
11
of a plurality of containers
13
as shown in
FIGS. 9 and 10
, each container receiving opening
20
of the plurality of container receiving openings
20
engages container
13
. Diamond-shaped openings
65
preferably form space within central regions of package
11
to create a handle.
Contour panel
70
according to this preferred embodiment of the invention, extends from longitudinal edge
25
of planar sheet
15
and conforms with an external contour of package
11
. Such a contoured engagement decreases the potential for protruding sections of carrier
10
to interfere or engage with adjacent packages
11
or other such goods.
Several features enable contour panel
70
to follow the external contour of package
11
. A height and length of contour panel
70
are reduced relative to carrier
10
that, in part, enables contour panel
70
to follow the external contour of package
11
. In addition, multiple panel straps
75
connecting planar sheet
15
at predetermined intervals along longitudinal edge
25
assist in retaining contour panel
70
against the external contour of package
11
. Specifically, two panel straps
75
connecting longitudinal edge
25
directly adjacent a center rank container receiving opening
20
and one panel strap
75
connecting longitudinal edge
25
directly adjacent each end rank container receiving opening
20
.
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 carrier
10
is 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.
