saw a or 3 1 CONTAINER CARRIER SUMMARY OF THE INVENTION The present invention is concerned primarily with improvements in container carriers of the manually transportable type adapted to support a plurality of rows of containers such as bottles and the like. The term six pack has been in common use to identify a manually transportable carrier for containers, such as bottles, cans, and the like. Some of the six pack type carriers heretofore available are not reusable, because of the mutilation of the carrier which occurs as the containers are removed. It is also important that in order to render a carrier reusable it must be so designed as to enable the removal of the normal accumulation of soil, stain, etc. Another significant factor to be considered in the production of multi-pack containers of the type contemplated by the present invention is to assure compactness when in folded condition to facilitate storage and shipment thereof.

It is an important object of the present invention to provide a multi-pack container of novel, collapsible and expandable form which will greatly facilitate the ease with which containers may be inserted within the expanded carrier and subsequently removed therefrom so as to permit subsequent collapsing of the carrier to a relatively small, flat multi-ply structure.

It is a further object of the present invention to provide a novel, container carrier of the type set forth above which may be produced very economically. To this end it is contemplated that suitable sheet plastic material may be employed requiring a minimum quantity of sheet stock without sacrificing carrier strength and without impairing efficiency in the retention of containers supported thereby.

More specifically, the present invention contemplates a container carrier formed from a single sheet of stock in which a unique arrangement of apertured sidewalls of the container function to permit convenient insertion and withdrawal of containers and protect the containers against lateral displacement.

The present invention also contemplates a carrier device of improved practical construction wherein a novel arrangement ofa readily foldable plastic sheet of relatively light weight conveniently washable material may be employed in the fabrication thereof.

BRIEF DESCRIPTION OF THE DRAWINGS The foregoing and other objects and advantages will be more apparent from the following detailed description when considered in connection with the accompanying drawings wherein:

DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION Referring now to the drawings more in detail, wherein like numerals have been employed to designate similar parts throughout the various figures, it will be seen that one embodiment of a container carrying device of the type contemplated by the present invention illustrated in FIGS. 1 to 8 inclusive is designated generally by the numeral 14. A foldable blank of sheet material, preferably plastic sheet stock, is illustrated in FIG. 4. In order to more readily understand the function and structure of the various sections or parts of the plastic sheet blank when in its folded, containeraccommodating position, reference will now be made to the disclosure in FIG. 4. A central transverse fold line, designated by the dot-and-dash line 16, divides the blank into two identical units, designated generally by the letters X and Y. Intermediate transverse bottom sections of the units X and Y are designated by the numerals 18 and 20, respectively. The section 18 is provided with a row of apertures 22, and the section 20 is provided with a row of similar apertures 24. As will later be explained, the elongate transverse sections 18 and 20 form the support for the bottom of a plurality of containers or bottles 30.

Extending from the outer margin of the containersupporting section 18 is a sidewall. section 26, and extending from the outer margin of the elongate bottle supporting section 20 is a similar oppositely disposed sidewall section 28. Elongate vertically disposed apertures 32 in the sidewall section 28 are of predetermined shape to accommodate the above-mentioned bottles 30 after the plastic sheet blank has been folded and expanded to the position illustrated in FIGS. 1 to 3, inclusive. Likewise, the sidewall section 28 is provided with similar container accommodating recesses 34. Extending from the inner margin of the elongate bottom section 18 is a central section 36, and extending from the inner margin of the adjacent elongate bottom section 20 is a corresponding central section 38. These sections 36 and 38, when brought into contact with each other by folding along the dot-and-dash line 16, provide registering hand- accommodating handle apertures 40 and 42, respectively.

The manner in which the plastic sheet blank illustrated in FIG. 4 may be folded and laterally expanded to accommodate the bottles 30 will now be described. The central wall sections 36 and 38 are first folded along the line 16 so as to bring said sections into abutting relation, as illustrated in FIGS. 6 and 7. The elongate section 18 is now folded along a dot-and-dash line designated by the numeral 44, and the elongate section 20 is similarly folded along a dot-anddash line 46, so as to bring the bottom sections 18 and 20, together with their adjacent wall sections 26 and 28, respectively, into engagement with the outer surfaces of their respective central sections 36 and 38. When thus folded, the sections will appear as illustrated in FIGS. and 6, namely as a compact four-ply sheet arrangement. With the above-described sections thus folded, the upper abutting margins ofthe sidewall sections 26 and 28 may be joined by heat sealing in areas designated by numerals 48 and 50, FIG. 5. Similarly, the lower abutting margins of the central sections 36 and 38 may be joined as by heat sealing in the areas designated by the numerals 52 and 54. The presence of the apertures 22 and 24 makes it possible to perform this heat sealing operation without affecting any other portion of the sheet stock.

Attention is now directed to additional fold lines 56 and 58 in the unit X and corresponding fold lines 60 and 62 of the unit Y, said fold areas being designated by dot-and-dash lines. When the outer sections of the sheet material are expanded laterally from the flat position illustrated in FIG. 6 toward the partially expanded position illustrated in FIG. 7, and ultimately to the final position of expansion illustrated in FIG. 2, the functional significance of the fold lines 56, 58, 60 and 62 will be more apparent.

It will be apparent from the foregoing that as the sidewall sections 26 and 28 are moved outwardly or laterally from the position shown in FIG. 6 to the position illustrated in FIG. 2, the vertical elongate openings 32 and 34 are conditioned for receiving the containers 30. When the containers 30 are positioned within these apertures, as illustrated in FIGS. 1 to 3 inclusive, the edges of the sheet material defining the apertures 32 and 34 are so shaped as to substantially conform with and engage the peripheries of the containers and thereby prevent lateral displacement thereof. To prevent the dislodgment of containers 30 positioned at each extremity of the rows thereof, a narrow strip 64 is sheared from the end margin of the sidewall section 26, and a similar narrow strip 66 is sheared from the opposite side of sidewall section 28 and heat sealed at the area designated by the numeral 68, FIG. 2. Similar strips 70 and 72 are sheared from the opposite extremity of the sidewall sections 26 and 28 and are joined at 74, as by heat sealing. It will thus be apparent that the presence of the strips 64 and 66 at one extremity and the corresponding strips 70 and 72 at the opposite extremity will prevent dislodgment of the containers 30 in the vicinity thereof. During the lateral expansion of the sidewall sections 26 and 28 the upper margins of said sidewalls move downwardly, thereby exposing the registering hand-accommodating apertures 40 and 42, as clearly illustrated in FIG. 1. Relative telescopic movement of the sidewall sections from the central sections 36 and 38 is limited by reason of shoulders 76 on the central section 36 and corresponding shoulders 78 on the central section 38. These shoulders are adapted to engage the heat-sealed portions 48 and 50, and thereby limit the extent of relative shifting of the upper margin of the sidewall sections 26-28 and the central abutting wall sections 3638.

In FIGS. 9 and 12, inclusive, a modified form of plastic sheet type carrier contemplated by the present invention is designated generally by the numeral 14a. As previously described, the carrier 14 is produced from a strip in which the handle portions of the carrier are joined along a fold line 16, whereas the blank from which the carrier 14a is produced, as illustrated in FIG. 10, positions the handle portions at the opposite extremities and incorporates a fold line 16a at the juncture ofsidewall section 26a and 28a. Doband-dash fold lines corresponding with the fold lines previously described in connection with the plastic sheet blank in FIG. 4 are given similar identifying numerals bearing the suffix a. Likewise, all other structural features corresponding with the structures of the carrier 14 are identified with similar numbers bearing the suffix The blank of the carrier 14a is initially folded along the line 16a and the handle portions are threaded through a slit or opening 80, so as to ultimately occupy the position illustrated in FIGS. 9 and 11. It will be apparent that the container carrier 14a incorporates structural and functional advantages previously set forth in the description of the carrier 14.

The container carriers 14 and are readily collapsible to assume the compact flat relation illustrated in FIG. 6, thus rendering the carriers convenient for the purpose of storage or shipment. The sidewall sections are conveniently and instantaneously expandable to condition the carrier for accommodating containers. Likewise, upon removal of the containers the carrier may be collapsed into flat compact form. Also, the design ofthe carrier contemplated hereby is such as to enable convenient heat sealing at readily available exposed areas. It will also be apparent that the present invention contemplates the provision of a very practical and inexpensive returnable bottle carrier. By employing suitable high density polyethylene sheet material or the like, the carrier described herein may be very expeditiously die cut from a strip of plastic sheet stock, folded and heat sealed. Plastic sheet material may also be cleaned or washed with convenience, thereby facilitating the reusability of the device.

It has been found practical to have the containeraccommodating openings of substantially teardrop shape. In other words, each opening is defined by a pair of ledges of sheet stock which diverge upwardly.
