Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to U.S. Provisional Application, Ser. No. 61/993,378, filed on 15 May 2014. This U.S. Provisional Application is hereby incorporated by reference herein in its entirety and is made a part hereof, including but not limited to those portions which specifically appear hereinafter.

BACKGROUND OF THE INVENTION

1. Field of the Invention
This invention relates to a flexible carrier for carrying a plurality of containers such as bottles in a unitized, stackable package.
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 and/or similar containers that require unitization. Flexible plastic ring carriers are one such conventional container carrier.
Flexible plastic ring carriers having a plurality of container receiving apertures that each engage a corresponding container may be used to unitize groups of four, six, eight, twelve or other suitable groups of containers into a convenient multipackage. Flexible ring carriers may include a handle that extend upwardly and/or outwardly from the carrier to enable a consumer to carry the package.
Flexible ring carriers are typically fed across a rotating applicating drum having a plurality of jaws that open the individual container receiving apertures to stretch them around a respective container and then release them onto the container. In this manner, a package of multiple containers is formed.
Multiple packages of cans may be stacked one upon the other to present a point-of-purchase retail display. However, packages of bottles are often more difficult to stack when packaged in this way because of the lack of support surfaces on the respective tops of the bottles. As such, a need arises for a package configuration that permits a package of bottles to be stacked one upon another yet results in an aesthetically pleasing package to the consumer

SUMMARY OF THE INVENTION

The present invention is directed to a flexible carrier for packaging containers that includes an arrangement of container receiving apertures that are generally rectangular and engage a plurality of containers having cooperative base and top geometries to permit stacking of packages of unitized containers, one upon the other.
According to preferred embodiments of this invention, each flexible carrier preferably includes two rows of container receiving apertures, each for receiving a container, to form a package. In addition, a handle is preferably connected between or along at least one row of container receiving apertures. The resulting package may be stacked one on top of the other so that each respective container of one package includes a base that cooperates with the top of a container in a package below.

BRIEF DESCRIPTION OF THE DRAWINGS

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:

FIG. 1 is a side elevational view of a flexible carrier according to one preferred embodiment of this invention;

FIG. 2 is a side perspective view of a package of containers according to one preferred embodiment of this invention; and

FIG. 3 is a side perspective view of two stacked packages of containers according to one preferred embodiment of this invention.

DESCRIPTION OF PREFERRED EMBODIMENTS

FIGS. 1-3 show flexible carrier 10 for unitizing two or more containers 80 and a resulting unitized package 100. Although FIGS. 1-3 illustrate various structures for flexible carrier 10 of the invention, the illustrations are exemplary, and the invention is not limited to the flexible carriers 10 or packages of six containers shown in FIG. 2. For example, flexible carrier 10 may be alternatively configured and used to unitize four, eight, ten, fourteen or any other desired number of containers 80.
Containers 80, such as those shown in FIGS. 2 and 3, are preferably bottles, however, cans or any other commonly unitized container may be used with flexible carrier 10 according to this invention. The containers 80 are preferably, though not necessarily, like-sized within a single flexible carrier 10. Each container 80 includes cooperative base and top geometries to permit stacking of containers 80 and thus packages 100 of unitized containers 80, one upon the other. More specifically, the bottles preferably include a recess in a base that cooperates with a cap on a top of the container such that one package of containers 80 may be placed on another package of containers 80 and lateral movement of a top package is thus restricted by the engagement between the recess in the base of each container in the top package and the cap of each container in a bottom package. More specifically still, each container includes a generally square cross-section and a round base depression that corresponds with a round cap in an adjacently stacked package. In this manner, the round cap may fit entirely within the base depression to secure the stack of packages. The resulting stack of packages 100 is generally balanced, rigid and sturdy, as best shown in FIG. 3.
Each flexible carrier 10 preferably includes one or more layers of flexible sheet 20 having a width and length defining therein a plurality of generally rectangular container receiving apertures 25, each for receiving a container 80. The plurality of container receiving apertures 25 are preferably arranged in longitudinal rows and longitudinal ranks so as to form an array of container receiving apertures 25, such as two rows by three ranks for a six container multipackage as shown in FIGS. 2 and 3. Container receiving apertures 25 are preferably generally rectangular shaped. In a preferred embodiment, outer webs of carrier 10 are narrower than center webs to enhance tightness of the resulting package 80 and permit predictable stacking of multiple packages 80.
As described above, the plurality of container receiving apertures 25 are preferably arranged in an array. In this manner, an array of rows and ranks of containers 80 in the package 100 can cooperate with a corresponding array of other containers 80 in a stack of packages 100. According to a preferred embodiment of this invention, the carrier 10 is positioned along the top third of the container 80, thereby minimizing interference in the bottom and cap areas of each container 80 so that stacking is not compromised.
Handle 50 may comprise one or more elongated apertures 55 positioned along the outer periphery of handle 50 or may comprise a similar configuration that provides an ample area for a consumer to grasp by inserting his hand through and still maintain the purpose and integrity of the package 100. As shown, handle is preferably positioned along the three-wide side of package 80. A tear strip 60, such as shown in FIG. 1, may be positioned along one or more edges of the carrier to facilitate removal of the respective containers.
As shown in FIG. 3, the package 100 resulting from flexible carrier 10 includes a plurality of unitized containers 80. Flexible carriers 10 are generally applied to containers 80 by stretching flexible sheet 20 surrounding container receiving apertures 25 around container 80, and requiring the stretched carrier 10 to recover, thereby providing a tight engagement.
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 flexible carrier 10 and package 100 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.

Claims

I claim:

1. A package of unitized containers comprising:

a flexible plastic carrier having an array of container receiving apertures;

a plurality of containers, each container having a cooperative base and top geometry to permit stacking of packages of unitized containers, one upon the other, wherein each container receiving aperture is engaged with a corresponding container to form the package of unitized containers.
