CARRIER DEVICE

Abstract: A carrier device (10) for uniting a plurality of containers (20) comprising annular bands (14) defining a plurality of apertures (12) generally arranged in ranks and rows. Annular bands (14) defining adjacent pairs of apertures in a given row being integrally connected by webs (16) and bands (14) defining apertures (12) in a given rank being integrally connected by spaced webs (17). Adjacent spaced webs (18) present margins (17) defining spaces (22). A tab (24) is connected to a marginal portion (17) of one side of the space (22) by non-detachable means (28) and is frangibly connected to a marginal portion (17) of an opposite side of the space (22) by frangible or detachable means (26). This provides a tab which is only removeable using a cutting tool after the carrier (10) is removed from its associated containers (20).

Description: This invention relates to a carrier device for containers such as cans and the like. Carrier devices formed from a resilient elastic deformable sheet of plastics material for uniting a plurality of containers comprising a plurality of apertures surrounded by annular bands arranged in ranks and rows, adjacent pairs of apertures in a row being integrally connected by web means and adjacent pairs of apertures in a rank being integrally connected by additional web means the additional web means presenting margins defining a space, are well known in the art. Examples of this type of carrier are shown in US-A-4,064,989; US-A-3,721,337; US-A-2,997,164 and US-A-3,733,100. In US-A-4,462,494 it is shown that it is possible to weaken a portion of the additional web means adjacent their margins defining such a space so that the portions of the additional web means can be folded and the spaces used as comfortable finger holds. It is also known to provide removable tabs on packaging which can provide proof of purchase of the product packaged in the packaging in a product sales promotion. Some of the earlier carrier devices mentioned above include tabs designed so that they could be pulled by the user to sever the carrier to release the containers from the carrier devices. Such tabs are easily removable before the merchandise is purchased and thus are not appropriate for use as proofs of purchase. According to this invention such a carrier device includes a tab transversing the space between a first and a second of the additional web means, the tab being connected to a first marginal portion of one side of the space by non-detachable means and being frangibly connected to a second marginal portion of another side of the space by detachable means, whereby a user can apply pressure to the tab thereby tearing the detachable means and disengaging the tab from the second marginal portion, the tab remaining secured to the first marginal portion of the space by the non-detachable means. An advantage of this invention is that it provides a carrier device for containers such as cans and the like which includes a tab which is frangibly connected to the device. The tab is connected to the remainder of the device so that it lays flat in the same plane as the remainder of the carrier device. Further the tab is connected to the carrier device so that it cannot be easily removed by the purchaser until the containers are removed from the carrier device. Particular examples of carrier devices in accordance with this invention will now be described with reference to the accompanying drawings; in which: Figure 1 is a plan of a first example; Figure 2 is a plan of the first example after it is applied to a group of containers; Figure 3 is an enlarged partial cross-section taken along lines 3-3 of Figure 2 and showing a user applying pressure to the tab to force it in a downward direction; Figure 4 is a fragmentary perspective view showing the user disengaging the proof of purchase tab from the remainder of the carrier device; Figure 5 is a plan of a second example; and, Figure 6 is a plan of a third example. Figures 1 through 4 of the drawings show the preferred embodiment of carrier device 10. Such carrier device 10 is typically made from a resilient sheet of tough elastic plastics material such as polyurethane or polyethylene. The carrier device 10 includes annular bands 14. The bands 14 define a plurality of apertures 12 arranged generally in ranks and rows. Adjacent pairs of apertures 12 and bands 14 in each row are integrally connected by webs 16 and each adjacent pair of apertures 12 and bands 14 in each rank are integrally connected by a plurality of spaced junction lines or webs 18. The webs 18 present margins 17 defining spaces 19 and enlarged space means or finger holes 22. The carrier device 10 is typically provided with three lateral ranks of two longitudinal rows of apertures and bands, but can be made with any desired number of ranks and rows. The number of apertures 12 is equal in number to the number of containers to be associated therewith. The carrier device 10 can be used in connection with a variety of types of containers 20 including but not limited to cans, bottles and the like. The apertures 12 are dimensioned so that the bands 14 frictionally and resiliently engage the body (not shown) of the containers 20. In the preferred embodiment of this invention a tab 24 is connected to opposite sides of at least one finger hole 22. Tab 24 is frangibly connected to a portion of the margin 17 of one side of the finger hole 22 by a detachable means 26. The detachable means 26 is cut, slit or perforated so that it can tear easily. The tab 24 is securely attached to a portion of the margin 17 of the opposite side of the finger hole 22 by hinge means or non-detachable means or junction line 28. The non-detachable means or hinge is not perforated. Generally, plastic of the type used to form carrier device 10, cannot be easily torn without the aid of some type of sharp instrument. As shown in Fig. 2, the location of tab 24 makes it difficult to remove the tab without first removing the containers 20. This is an important feature of this invention because the tab 24 is intended to provide a proof of purchase device. It should be readily apparent that tab 24 can also be used to clearly display the manufacturer's or seller's logo. As shown in Fig. 3, when it is desired to pick up the package a user first applies pressure to tab 24, by inserting a finger in the finger hole 22, so that the detachable means 26 tears and one side of the tab 24 is disengaged from the carrier device 10 and forced in a downward direction. Thus, the user can easily use the finger hole 22. As shown in Fig. 4, the tab 24 is still securely connected to the carrier device 10 at hinge line 28. Hinge line 28 is not perforated or slit and therefore cannot easily be detached from the carrier device 10. When the containers 20 are removed, the purchaser can remove the proof of purchase tab 24 by cutting along hinge line 28 with scissors 29 or other cutting tools. Turning now to Fig. 5 there is shown carrier device 10a. Carrier device 10a is an alternative form of carrier device 10 and includes elements corresponding to those described above as indicated by the application of the same reference numerals with the suffix a added thereto. However, as shown in Fig. 5, tab 24a transverses at least one space means 19a rather than a finger hole. The tab 24a is secured to a marginal portion 17a of one side of the space means 19a by detachable means 26a and is frangibly connected to a marginal portion 17a of an opposite side of space means 19a by hinge means or non-detachable means 28a. As the user applies pressure to tab 24a, the frangible means 26a tears and one side of tab 24a is detached from carrier device 10a. Tab 24a is still securely attached to the carrier device 10 by hinge means 28a. The user can then detach the tab 24a from the carrier device 10a by cutting along hinge line 28a. Turning now to Fig. 6, there is shown a carrier device 10b. Carrier device 10b is another alternative form of the invention in which elements similar to those described above are designated by the same reference numerals with the suffix b added. As shown in Fig. 6 adjacent pairs of apertures 12b in each row and bands 14b are integrally connected by webs 16b. Adjacent pairs of apertures 12b in each rank and bands 14b are integrally connected by single web means 32. The adjacent single web means 32 define first and second finger holes or enlarged space means 34 and 36. Finger hole 34 includes a tranverse bar 38 which bisects the finger hole 34. A tab 24b transverses finger hole 36. Tab 24b is frangibly connected to portions of the margin 17b of one side of hole 36 by detachable means 40 comprising a perforated line or junction area. Tab 24b is also connected to portions of the margin 17b of an opposite side of hole 36 by non-detachable means or junction lines 42 and 43. As before, as a user applies pressure to tab 24b the detachable means tears or breaks detaching one side of tab 24b from the carrier device 10b. Junction lines 42 and 43 can then be cut with a scissors or the like to completely separate the tab 24b from the carrier device. It should be noted that another feature of this invention is that the tabs 24, 24a or 24b are not free to move or flap relative to the plane of the carrier devices 10, 10a and 10b during initial production of the carrier device and application to the cans or other containers. This feature prevents the tabs 24, 24a, 24b from interfering with the production and assembly process. In assembly, the carrier devices 10, 10a and 10b are stretched over containers 20 by suitable devices (not shown) which have been placed in a close array defined by ranks and rows. Since the tabs 24, 24a or 24b are connected to both sides of the spaced means 22 or 34 the tabs 24, 24a or 24b are not free to move relative to the plane of the carrier devices 10, 10a and 10b. This will permit the carrier devices 10, 10a and 10b to be easily handled and wound in assembly.
