Each of the known devices have features which make them advantageous for particular container applications. From the standpoint of market penetration; however, apertured plastic sheet carrier devices of the type disclosed in U. S. Pat. No. 2,874,835 have had the widest impact in the can multipackaging field because of the economic advantages over the multi-packaging devices and their adaptability to high speed applicating equipment. The present invention is directed to a plastic multi-packaging device which is generally similar to apertured plastic sheet carrier devices, but which has distinctly different and improved aspects providing marked advantages thereture, require special storage and shipping reels, and demand certain sheet material thicknesses and machinery requirements due to the manner in which the material which surrounds the apertures in the plastic sheet is stretched and deformed to the shape of tubular necks prior to the application to containers.

Accordingly, it is an object of the present invention to provide a new and improved plastic multi-packaging device and container package.

More specifically, it is an object of the present invention to provide a plastic multi-packaging device which facilitates manufacture, shipment and storage and the use thereof in forming container packages.

Another object of the present invention is to provide a new and improved method for manufacturing plastic muIti-packaging carrier devices for containers.

These and other objects and advantages of the present invention are attained by the provision of a plurality of flattened bands of stretchable and elastic plastic material which are at least initially interconnected to each other so as to provide a succession of material bands when opened. The method of the present invention is achieved by forming, in at least one elongated flattened tube of stretchable and elastic plastic material, a plurality of pairs of parallel slits each defining flattened material bands with connecting webs between the flattened bands which provide an interconnected series of flattened material bands.

DESCRIPTION OF THE PREFERRED EMBODIEMENTS It will be apparent from the discussion that is to follow that whereas the prior art apertured sheet plastic carrier devices are formed or stamped from a sheet or web of plastic material, the multi-packaging or carrier devices of the present invention are formed from one or more flattened tubular plastic elements. This background understanding is important in order to appreciate the structural and functional improvements of the present invention over the prior art, as will now be described.

The container package shown in FIGS. 1-3 of the drawings includes a plurality of cans or containers 12 which are arranged in the well known six-pack multipackage configuration. Each of the cans 12 are depicted as having upper and lower annular enlargements or

chimes

14, 16 at opposite ends thereof. In addition to cans with upper and lower annular enlargements as illustrated in the drawings, the present invention has equal application to containers with an upper enlargement only or with no annular enlargements at all, although preferably there is at least an upper annular enlargement for each can.

Each can 12 is gripped and held together as a unit in the container package 10 by the multi-packaging or.

carrier device 18. It will be noted, from FIGS. 1-3 of the drawings, that the multi-packaging device 18 includes a plurality of interconnected circumferential bands of material 20 which grip each can 12 preferably immediately below the upper annular enlargements 14 thereof. Each of the circumferential bands of material 20 is joined to an adjacent band through connecting webs 22 which are more specifically identified as described hereinafter.

In order to grip the cans 12 in the aforesaid manner, the multipackaging device 18 is formed from a flattened tubular element of stretchable and elastic plastic material, polyethylene being one preferred example. It will be apparent that the circumferential bands of material 20 are arranged to have a peripheral dimension, prior to assembly to the cans 12, such that the material bands 20 can be stretched over the cans, by suitable applicating equipment, into elastic and embracing gripping relationship relative to the cans 12. When so assembled to the cans 12, the multi-packaging device 18 forms a container package 10 where the cans 12 are held together as a group for carrying and transporting purposes. It will be noted, from FIG. 2 of the drawings, that the fingers of a user may be inserted into the diamond shaped openings formed by the container package 10 for gripping the sides of the intermediate or central cans 12 for lifting and transporting the container package 10.

Reference is now made to FIGS. 4-7 of the drawing for an understanding of how the multi-packaging device 18 is made and constructed. In FIG. 4 of the drawings, there is shown a pair of integrally continuous flattened tubular elements 24 each having opposed folded ends 25 which are joined together at one folded end 25 thereof as at 26. While the interconnected flattened tubular elements 24 may be formed in any suitable manner, they are preferably profile extruded in generally the form illustrated in FIG. 4. It will be apparent that the tubular elements 24 will be more nearly flattened during the fabrication of the multi-packaging device 18 than the slightly exagerated spacing between the walls of the tubular elements in this and subsequent embodiments to be described. Also, the tubular elements 24 may be extruded in a more rounded elliptical or circular shape and then subsequently flattened before being fabricated into multi-packages. The portion 26 which joins the flattened tubular elements 24 is a thickened web which connects the flattened tubular elements 24 at one folded end 25 thereof.

After the flattened tubular elements 24 have been formed in generally the manner exhibited in FIG. 4 of the drawings, it is then possible to form an interconnected series of flattened material bands to provide multi-packaging devices 18. As is best seen in FIG. 5 of the drawings, this is accomplished by slitting the flattened tubular elements 24 so as to provide a plurality of interconnected flattened material bands 28. Each of the material bands 28 is formed by a pair of

parallel slits

30, 32 which extend throughout the flattened tubular elements 24 except at the connecting

webs

34, 36 respectively. It will be seen that each pair of

slits

30, 32 is formed to provide a pair of connecting

webs

34, 36 on each side of the thickened web 26 connecting the flattened tubular elements 24. It will be noted from the full and dotted line impressions of each pair of connecting

webs

34, 36 that the connecting webs are provided on opposite walls of the flattened tubular elements 24 in order to permit the flattened bands 28 to open up and form the tubular or circumferential bands 20 of the multi-packaging device 18 for assembly to the cans 12.

This is best seen in FIG. 6 of the drawings where the flattened bands 28 are shown from the flattened to the fully opened position. As will be apparent, the opposite, alternating arrangement of the connecting

webs

34, 36 for each flattened material band enables the bands 28 to open up in a continuous succession of multi-packaging devices 18. This will permit the multipackaging devices 18 to feed one another during the assembly thereof by applicating equipment to cans 12. It is contemplated that the multi-packaging device 18 will be separated from the interconnected series of material bands after assembly to the cans 12.

When fully opened, a multi-packaging device 18 will closely resemble the configuration illustrated in FIG. 7 of the drawings. As will be seen, each of the interconnected bands of material 20 assumes a generally tubular shape when opened up. This makes it unnecessary for each of the generally tubular bands 20 to be stretched to form tubular necks as in the case of apertured sheet plastic carriers prior to assembly to cans. The tubular bands of material 20 as in the present invention also makes it possible to predetermine the thickness or gauge of the walls of the tubular bands 20 so as to provide the least usage of material. In theprior art apertured sheet plastic carrier devices, the apertures are non-uniformly stretched to the shape of tubular necks prior to the assembly to cans and this makes it difficult to control or utilize the least amount of material for multi-packaging applications. With the present invention; however, the opening up of the material bands to the shape illustrated in FIG. 7 of the drawings makes it possible to uniformly stretch the tubular bands 20 for application to cans 12 as well as control the band thickness with more preciseness.

The connecting

webs

34, 36 interconnect opposite, alternating marginal edges of adjacent material bands 20. This results in a multi-packaging device 18, as illustrated in FIG. 3 of the drawings, where the connecting webs (generally designated by numeral 22) join adjacent material bands 20 upper and lower marginal edges thereof. This will not affect the performance of the multi-packaging device IS since the material bands 26 are capable of engaging the cans 12 at generally the same circumferential location thereof. While the connecting

webs

34, 36 as shown in FIG. 7, join the material bands 26 in the same row, the connecting webs 3S join opposite material bands 26 in adjacent rows. The connecting web 33 is formed from the thickened web 26 when the

slits

36, 32 are formed in the flattened tubular elements 24. As will be'noted, the connecting webs 38 in the multi-packaging device 13 are smaller than the connecting

webs

34, 36 since the thicknesses of the thickened web 26 is less then the width of the connecting

webs

34, 36.

Where a single row of interconnected material bands is desired, it will be apparent that the

slits

30, 32 with the corresponding connecting

webs

34, 36 respectively need to be formed only in a single flattened tubular element 24. It will be apparent from the other embodiments of the present invention, that more than two tu-' bular elements 24 may be extruded, depending on the particular multi-packaging device that is desired.

In the embodiments of the present invention that will now be described, similar reference numerals will be used to designate like parts in the various embodiments with the use of alphabetical suffixes to distinguish between the various embodiments.

As is illustrated in FIGS. 6-9 of the drawings, a multipackaging device IS of the type illustrated'in FIG. 7 of the drawings may be formed by a different construction of the flattened tubular elements and the manner in which the tubular elements are slit. Specifically, the flattened tubular element 24a are attached at an intermediate section 40 along the sides or maximum flattened dimension thereof rather than at one end of the tubular elements as shown in the FIG. 4 illustration. In order to form the multi-packaging device 13 in FIG. 7, a plurality of pairs of

parallel slits

36a, and 32a are formed in each of the superimposed tubular elements except at opposite ends thereof. Thus, the slit 30a extends throughout each of the superimposed tubular elements 240, but terminates short of the upper end of the tubular elements as illustratedin FIG. 9 while the slit 32a extends throughout each of the superimposed tubular elements 240 from the upper end thereof, but terminates short of the lower end thereof in FIG. 9. Each of the slits 30a, 320 are terminated at opposite ends by the small circular holes 42 which prevent the slits from tearing into the plastic material. The unslit areas of the tubular elements 24a at opposite ends thereof from the connecting

webs

34a, 36a which join adjacent material bands 26a in the same row while the thickened connecting section 40, when severed by the

slits

36a, 32a forms the connecting or joining section between opposite material bands in adjacent rows.

Reference is now made to the embodiment shown in FIGS. Ill-12 of the drawing. In FIG. 110, there is illustrated a plurality of pairs of interconnected flattened tubular elements 24b where each pair of tubular elements 24b are joined to each other along the sides or maximum flattened dimension thereof at an intermediate portion 4012 while adjacent pairs of tubular elements 24b are joined to one another at one end thereof as at 26b. Thus, the arrangement is a combination of the method of joining the tubular elements to one another as illustrated in FIGS. 4 and S of the drawings.

As has previously been explained, the tubular elements 24b may be extruded in generally the flattened shape illustrated or in a more opened up form and subsequently flattened following extrusion. In either case, the arrangement of the tubular elements 24b is generally that which is illustrated in FIG. 16 of the drawings prior to forming the material bands by slitting of the tubular elements 24b. The spacing between the walls of each tubular element may, however, be less than that shown prior to and during the slitting operation.

In FIG. II of the drawings, it will be seen that the slits 30b and 321) which form the material bands 28b are formed throughout each of the tubular elements 24b except at the lower and upper ends of the tubular arrangement. Specifically, the slit 36b extends throughout each pair of superimposed tubular elements 24b except at the connecting web 46. Similarly, the slit 32b extends throughout the tubular elements 24b except at the upper end of the uppermost pair of tubular elements 24b where the connecting web 43 is provided. By slitting the tubular elements 24b in the aforesaid manner, there is provided, as best seen in FIG. 12 of the drawings, a plurality of interconnected multi-packaging devices 1812 which are joined at opposite ends thereof by the connecting

webs

46, 48 respectively. Because I each of the multi-packaging devices llSb includes a material band 26b which is formed from each of the tubular elements 24b, the connecting

webs

26b, 40b which connect material bands 28b in the same and adjacent rows will be of substantially uniform size as compared with the non-uniform in

size connecting webs

34, 36 and the connecting webs 36 in the FIGS. 1-9 embodiments. The uniform or non-uniform size of the connecting webs results from the manner in which the tubular elements are connected to one another and the method of slitting, but in either case, they do not affect the functioning of the multi-packaging device.

The embodiments shown in FIGS. 13-15 of the drawings is similar to FIGS. 10-12 except that in this case, the tubular elements are slit so as to leave intermediate connecting webs between adjacent multipackaging devices. Specifically, it will be seen that the plurality of pairs of flattened tubular elements 24c are connected to each other as at 46c and connected to adjacent pairs of tubular elements 24c as at 260. This is the same configuration as is shown in FIG. lit) of the drawings. However, in slitting the plurality of pairs of tubular elements 24c, the slits 3tlc,'32c are arranged to leave opposite altemating intermediate connecting webs 5th, 52 respectively so that adjacent multi-packaging devices llSc are connected along the sides or maximum flattened dimension thereof to one another as is best illustrated in FIG. 15 of the drawings. Thus, each multi-packaging device the will unfold with respectto an adjacent multi-packaging device by opening up along the sides rather than the end to end connected arrangement illustrated in FIGS. -112 of the drawings. As in the FIGS. 10-112 embodiment; however, the connecting

webs

26c and 40c in each multi-packaging device will be substantially uniform in size, as will be apparent.

The various embodiments of the present invention that have been shown are to be considered in an exemplary sense only as the multi-packaging device can be manufactured and used in various multiples in single or plural rows. Also, while the discussion has centered principally on canned products, the multi-packaging device can be used with containers of other shapes and sizes. Further, adjacent tubular bands of the multipackaging device may be frangibly connected to one another in order to keep the tubular bands with individual container when separated from the remainder of the container package.

From the foregoing, it will now be appreciated the present invention comtemplates a new and improved multi-packaging device and a method of manufacture thereof which provides efficient and economic utilization of material during the manufacture, storage and assembly thereof to containers in a manner which has not been heretofore possible. The variety of multipackaging applications and the types of products that can be packaged by the multi-packaging device makes it adaptable to wide commercial use.
