Carrier

Abstract: This invention relates to a package (1) of a plurality of containers (5) unitized with a flexible carrier (10). The carrier (10) is constructed from a plastic planar sheet having a plurality of container receiving openings (20) including corner container receiving openings (25) and inner container receiving openings (40). A panel (50) is positioned with respect to a straight longitudinal panel edge (55) of the container receiving openings (20). When the containers (5) are inserted into the container receiving openings (20), the panel (50) remains flat and tight with respect to the containers (5). The panel (50) is urged into a flat position with respect to the containers through a distinct spatial relationship between and among the container receiving openings (20).

Description: This invention relates to a carrier according to the preamble of claim 1, for unitizing a plurality of containers, having a plurality of container receiving openings configured to allow an integral panel to remain in a flat and tight position with respect to the containers. It also relates to the resulting package. 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. An example is disclosed in EP-A-0507479, corresponding to the preamble of claim 1 which does not include an advertising or promotional printing space but does include a panel for a handle. 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. An object of this invention to provide a container carrier that unitizes a plurality of containers into a tight, solid package and yet also provides a panel for merchandising information. Accordingly, the invention consists in a carrier for carrying a plurality of containers, the carrier including a planar sheet of a plastic material, the sheet having a plurality of container receiving openings arranged in longitudinal rows and transverse ranks; a corner container receiving opening of the container receiving openings located at an intersection between an outermost row of the longitudinal rows and an outermost rank of the transverse ranks, the corner container receiving opening having a first longitudinal length; an inner container receiving opening of the container receiving openings located in an inner rank of the transverse ranks, the inner container receiving opening having a second longitudinal length; a panel integrally formed with the sheet, the panel extending outward from a panel edge of the sheet; and, the panel edge at least partially formed along a portion of each of the container receiving openings, the panel edge positioned in a longitudinal direction along a generally straight line; characterised in that the corner container receiving opening has an outer corner with a first radius, the inner container receiving opening has at least one corner with a second radius, and the first radius is greater than the second radius. An advantage of this invention is that it provides a container carrier that incorporates the stability and economy of a ring carrier and a promotional area like a box carrier. Preferably a first longitudinal band is also formed between transversely adjacent corner container receiving openings while a second longitudinal band is formed between transversely adjacent inner container receiving openings. The first longitudinal band is narrower than the second longitudinal band. In addition to the above features, the carrier may also include an integral handle, an end web, a flap in the corner container receiving openings and a line of perforation formed within the carrier. Such features as described above result in a carrier configured to carry a plurality of containers. 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. Particular embodiments of carriers in accordance with this invention will now be described with reference to the accompanying drawings; in which:- Fig. 1 is a top view of a carrier for holding six containers according to one preferred embodiment of this invention; Fig. 2 is a perspective view of a package of containers using a carrier according to one preferred embodiment of this invention; Fig. 3 is a top view of a carrier for holding six containers according to another preferred embodiment of this invention; Fig. 4 is a top view of a carrier for holding eight containers according to one preferred embodiment of this invention; and Fig. 5 is a top view of a carrier for holding twelve containers according to another preferred embodiment of this invention. Figs. 1-5 show carrier 10 for carrying a plurality of containers 5. Containers 5 shown in Fig. 2 are preferably cans. Although cans are shown in Fig. 2, bottles or any other commonly unitized container 5 may be used with carrier 10 according to this invention. Containers 5 are preferably like-sized within a single carrier 10. Carrier 10 unitizes a plurality of containers 5 to create package 1, such as package 1 shown in Fig. 2. Carrier 10 comprises planar sheet 15 preferably constructed from a flexible, resilient material such as plastic. In one preferred embodiment of this invention, sheet 15 is made from low density polyethylene. Sheet 15 preferably comprises two transverse edges 17 and two longitudinal edges 18. 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 sheet 15. Preferably, six or more container receiving openings 20 are formed in 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. Sheet 15 may include other configurations of container receiving openings 20 depending on the size of package 1 desired. Container receiving openings 20 comprise a plurality of corner container receiving openings 25 and a plurality of inner container receiving openings 40. Container receiving openings 20 are preferably longer in a longitudinal direction than wide in a transverse direction. Corner container receiving openings 25 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 25 located at each of four corners of sheet 15. Corner container receiving openings 25 have a first longitudinal length 28. Corner container receiving opening 25 also includes outer corner 30 having first radius 33. Inner container receiving openings 40 are located in an inner rank of the transverse ranks. Depending upon the capacity of carrier 10, sheet 15 preferably includes two or more inner container receiving openings 40. Inner container receiving openings 20 have a second longitudinal length 43. Inner container receiving openings 40 also include at least one corner, and preferably two corners, with second radius 45. According to the invention, first radius 33 is greater than second radius 45. Specifically, first radius 33 is preferably approximately 3/4" (18mm) or greater and second radius 45 is preferably approximately 1/4" (6mm). In this invention, panel 50 is integrally formed with sheet 15. Panel 50 preferably has an overall longitudinal panel length less than an overall length of longitudinal edge 18. Panel 50 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 1. Panel 50 is preferably generally continuous and unbroken, without cutouts or apertures, throughout its defined area. Panel 50 preferably extends outward from longitudinal edge 18 of sheet 15. Specifically, panel 50 extends outward from panel edge 55 of sheet 15. As shown in Figs 1 and 3-5, panel edge 55 is at least partially formed along a portion of each container receiving opening 20 that is adjacent to panel 50. Panel edge 55 is positioned in a longitudinal direction along a generally straight line. The generally straight line of panel edge 55 is formed to correspond to longitudinal length 53 of panel 50. First longitudinal band 60 is preferably formed between transversely adjacent corner container receiving openings 25. Second longitudinal band 65 is preferably formed between inner container receiving openings 40. In addition, transverse bands 68 are formed between each longitudinally adjacent container receiving opening 20. According to one preferred embodiment of this invention, first longitudinal band 60 is narrower than second longitudinal band 65. In one preferred embodiment of this invention, shown in Fig. 4, carrier 10 further comprises end web 75 positioned at each of two transverse edges 17 of sheet 15. End web 75 preferably comprises a band of material extending between corner container receiving openings 25 along transverse edges 17 of sheet 15. As shown in Figs. 1-3, in one preferred embodiment of this invention, carrier 10 comprises sheet 15 having six container receiving openings 20. In this preferred embodiment, first longitudinal length 28 of corner container receiving opening 25 is preferably greater than second longitudinal length 43 of inner container receiving opening 40. In alternative embodiments of this invention, first longitudinal length 28 of corner container receiving opening 25 is approximately equal to second longitudinal length 43 of inner container receiving opening 40. As shown in Figs. 4 and 5, carrier 10 comprises sheet 15 having eight or more container receiving openings 20. In this preferred embodiment, second longitudinal length 43 is preferably greater than the first longitudinal length 28. In one preferred embodiment of this invention, second longitudinal length 43 is approximately 8% larger than first longitudinal length 28. In a preferred embodiment of this invention shown in Figs. 3 and 5, carrier 10 further comprises integral handle 12 positioned along an opposite longitudinal edge 18 as panel edge 55 of sheet 15. Handle 12 is particularly important in configurations of carrier 10 that contain many container receiving openings 20 to facilitate ease of handling of package 1. As shown in Fig. 2, container 5 is positioned in each container receiving opening 20 to form package 1. Panel 50 is preferably flat and parallel with respect to containers 5 and prominent with respect to package 1. If panel 50 is curled or folded in a perpendicular position with respect to package 1, then advertising or other material positioned on panel will not be legible to a consumer. In addition, a panel 50 that protrudes with respect to package 1 will create difficulties in packaging, handling and stacking packages 1 because of interference between panels 50 of adjacent packages 1 and between panel 50 and packaging equipment. Several of the above described features of carrier 10 facilitate a flat and prominent panel 50 with respect to package 1. For example, the generally straight line formed by panel edge 55 urges panel 50 into a generally flat position with respect to containers 5 in package 1. In addition, the relative difference between first longitudinal length 28 of corner container receiving openings 25 and second longitudinal length 43 of inner container receiving openings 40, thereby creating an irregular longitudinal pitch between container receiving openings 20, also aids in the relative flatness of panel 50 with respect to package 1. The relative difference in width between first longitudinal band 60 and second longitudinal band 65 also creates a tighter unitized block of containers 5 within package 1, specifically at transverse edges 17 where panel 50 is most likely to curl. The result of a tight unitized block of containers 5 is a flat panel 50 with respect to package 1. In one preferred embodiment of this invention, shown in Fig. 4, sheet 15 further comprises flap 70 positioned in transverse band 68 adjacent one or more corner container receiving opening 25. Flap 70 is preferably positioned along one transverse band 68 adjacent corner container receiving opening 25. Flap 70 functions as a shim between container 5 and corner container receiving openings 25 thereby allowing transverse band 68 to fold at band slit 69 which further urges panel 50 into a flat position. According to one preferred embodiment shown in Figs. 1 and 3-5, carrier 10 further comprises at least one line of perforation 80 adjacent container receiving opening 20. Lines of perforation 80, preferably in combination with removal slits 85, are preferably positioned from an external edge of sheet 15, such as transverse edge 17, to an edge of container receiving opening 20. Therefore, when line of perforation 80 is separated, container 5 is more easily removable from carrier 10.
