A package for containers

Abstract: Substantially identical bottles (12) in a generally rectangular array are combined with a carrier (14) and with a tray (16) to form a package (10). The carrier (14) is made from a single sheet of low density polyethylene so as to have band segments (30) defining bottle-receiving apertures (28). The carrier (14) is applied to the bottles (12) so that outer band segments (30) of the carrier (14) embrace portions of side walls (24) of the outer bottles in the array. The tray (16) is made from a single sheet of cardboard and is folded so as to define a lower portion (38) underlying at least a portion of each bottle (12) in the array and two lateral portions (40). Each lateral portion (40) is folded upwardly from the lower portion (38) and is affixed adhesively to at least one of the outer band segments (30) of the carrier (14). Outer surfaces of the lateral portions (40) are suitable for imprinting or labelling.

Description: This invention pertains to an improved package comprising substantially identical containers, such as bottles for soft drinks or other beverages, together with a carrier. Commonly, cans, bottles, or other containers for soft drinks or other beverages are marketed in packages comprising four, six, eight, or twelve containers in machine-applied carriers made from single sheets of resilient polymeric material, such as low density polyethylene. The carriers are made, as by die-cutting, so as to have band segments defining container-receiving apertures. US-A-3700275 discloses a package comprising containers and a carrier according to the preamble of claim 1. Although such polymeric carriers have many advantages, particularly as compared to predominantly paperboard carriers, such polymeric carriers have some shortcomings. One shortcoming is that such polymeric carriers do not provide expansive surfaces for pricing, bar-coding, or other labelling of the packages. Another is that such polymeric carriers do not provide means for separating or stabilizing like packages in a stack. This invention has resulted from efforts to provide an improved package for cans, bottles, or other containers for soft drinks or other beverages. According to this invention, a package comprises substantially identical containers having side walls, the containers being arranged in a generally rectangular array including outer containers, a carrier made from a single sheet of resilient polymeric material so as to have band segments defining container-receiving apertures and including outer band segments, the carrier being applied to the containers so that the container-receiving apertures receive the respective containers and so that the outer band segments embrace portions of the side walls of the outer containers, characterised in that the package also comprises a tray made from a single sheet of foldable material and folded so as to define a lower portion underlying at least a portion of each container in the generally rectangular array and so as to define two lateral portions, each being folded upwardly from the lower portion at a fold in the folded sheet and each being affixed to at least one of the outer band segments of the carrier. The package in accordance with this invention provides expansive surfaces for pricing, bar-coding, or other labelling and provides means for separating and stabilizing like packages in a stack. Preferably, each of the lateral portions is affixed adhesively to at least one of the outer band segments of the carrier. More preferably, each of the outer band segments is affixed adhesively to at least two of the outer band segments of the carrier. The lateral portions of the tray provide expansive surfaces for pricing, bar-coding, or other labelling of the improved package. The lower portion of the tray provides means for separating like packages in a stack so as to stabilize the stacked packages. A particular example of a package in accordance with this invention will now be described with reference to the accompanying drawings, in which:- Figure 1 is a perspective view of an improved package according to this invention and comprising eight substantially identical bottles, a polymeric carrier, and a paperboard tray; Figure 2 is an exploded view of the package, as shown in Figure 1, after the carrier has been applied to the bottles but before the paperboard tray is positioned beneath the bottles, folded, and secured to the carrier; Figure 3 is an elevational view of two such packages in a stack. As shown, a package 10 comprising eight substantially identical bottles 12, a polymeric carrier 14, and a paperboard tray 16 constitutes a preferred embodiment of this invention. The bottles 12 are arranged in a generally rectangular array including two longitudinal rows, each including four bottles 12. This invention contemplates that the generally rectangular array may include more than two rows, a different number of bottles 12 in each row, or both. The bottles 12 may be predominantly polymeric bottles containing soft drinks. Each bottle 12 has a removable cap 20, which is mounted on a neck 22 of such bottle 12, a side wall 24, which is disposed below the neck 22, and a base 26, which is disposed below the side wall 24. The carrier 14 is made, as by die-cutting, from a single sheet of resilient polymeric material. A preferred material is low density polyethylene. A preferred thickness for such material, if low density polyethylene is used, is about 16 mils (0.4 mm). Any of various known carriers made from carrier stock available commercially from ITW Hi-Cone (a division of Illinois Tool Works Inc.) of Itasca, Illinois, may be suitably used as the carrier 14. The carrier 14 is made so as to have band segments defining bottle-receiving apertures 28 and including outer band segments 30. The carrier 14 is applied to the bottles 12, as by known machinery, so that the bottle-receiving apertures 28 receive the respective bottles 12 and so that the outer band segments 30 embrace portions of the side walls 24 of the bottles 12 in the outer rows. Suitable carrier-applying machinery is available commercially from ITW Hi-Cone, supra. The tray 16 is made from a single sheet of foldable, paperboard material, which may be single-ply paperboard, multi-ply paperboard, or corrugated paperboard with a single wall or with double walls. Single-ply paperboard is preferred. The tray 16 is folded along parallel folding lines 36 so as to define a lower portion 38 and two lateral portions 40. After the carrier 14 has been applied to the bottles 12, the tray 16 and the bottles 12 are disposed so that the lower portion 38 underlies the bases 26 of the respective bottles 12, whereupon the lateral portions 40 are folded upwardly from the lower portion 38. The lateral portions 40 are affixed adhesively to the certain of the outer band segments 30. Preferably, as shown, each of the lateral portions 40 is affixed adhesively to the outer band segments 30 embracing portions of the side walls 24 of the middle two of the bottles 12 in a respective one of the rows. Any of a wide range of adhesives is suitable. Particularly on the lateral portions 40 and additionally on the lower portion 38, the tray 16 provides expansive surfaces for pricing, bar-coding, or other labelling of the package 10, via imprinting or otherwise. Nonetheless, substantial portions of the respective bottles 12 remain exposed, which is desirable from a marketing standpoint. Furthermore, as shown in Figure 3, the lower portion 38 of the tray 16 is useful for separating and stabilizing like packages 10 in a stack. Although it is preferred for the lateral portions 40 to be adhesively affixed as and where noted above, the lateral portions 40 may be heat-sealed if suitable coatings or suitable materials are employed.
