CARRIER CLIP FOR CANS HAVING CHIMES ON ONLY ONE END Filed July 18, 1962 INVENTOR CHARLES E.

Waggner I'II, Chicago, 111., assiguor to Snap Pac Corporation, Houston, Tex., a corporation of Delaware Filed July 18, 1962, Ser. No. 210,807 3 Claims. (Cl. 220-102) This invention relates to improvements in carrying devices for cans. More particularly, it relates to a carrying device for a particular type of can which has chimes at one end only.
There are certain types of cans which have chimes at one end only. Deep-drawn aluminum cans are this type; these cans appear to be gaining favor rapidly and their usage is becoming more widespread. Although these cans have conventional chimes or ridges around the top thereof, so that they may be opened by the usual can openers, punches, and the like, the bottoms and the sides are a continuous single piece of metal eliminating the necessity of the use of chimes around the can bottom. Therefore, cans of this type present somewhat of a problem in holding them together in a package carrier clip, especially a carrier clip of the type which engages chimes at the top and bottom of the cans such as :shown in the commonly owned Canadian patent to Erickson 680,895. It is the principal object of this invention to provide a unique can carrying clip for cans of the type discussed above utilizing a cantilever support for supporting the bottoms of the cans and utilizing chime-engaging means for engaging the top of the cans.
A further object of this invention is to provide a can carrier clip which may be easily and inexpensively fabricated from plastic to be thrown away after a single use.
Although the invention is described for holding a plurality of cans with chimes at one end together in a unitary package, it will be apparent that it could also be used for holding similar shaped articles such as tumblers having a top ridge and a smooth bottom, and the like.
Other objects of the invention will be pointed out in the following description and claims and illustrated in the accompanying drawings, which disclose by way of example, the principle of the invention and the best mode which has been contemplated of applying that principle.
In the drawings:
FIG. 1 is a perspective view of the preferred embodiment of the can carrying device of this invention showing it in use holding a plurality of cans with chimes at one end only;
FIG. 2 is a plan view of one side of the blank used in forming the can carrier clip of this invention;
FIG. 3 is a side elevation view of the blank showing in dotted lines how the blank is formed to provide the erected carrier clip;
FIG. 4 is a detailed sectional View taken along line 44 of FIG. 2.
Referring to FIG. 1, the can carrier clip of this invention is particularly adapted for holding a number of cans 12 which may be of the deep-drawn aluminum type having a top chime 14 and a bottom 16 which is formed as an extension of the side walls without any chimes or ridges.
The carrier clip 10 includes a pair of upper platens 18 and 19 for engaging chimes 14 of cans 12. The platens 18 and 19 are integrally connected to an inner portion 20 and a carrying handle 22. The inner portion 20 is in turn integrally connected at the bottom thereof to a cantilever bottom support 24 which functions to rigidly support the bottoms of the cans 12.
The upper portion of the carrier clip 10 is quite similar to that shown in the commonly owned application of Wherry, Serial No. 200,126 filed June 5, 1962, and, in fact, can be molded from polypropylene plastic in the dies that would be used to mold the upper portion of the Wherry can carrier clip.
The platens 18 and 19 are identical and therefore only one will be described in detail. Platen 19 includes four curved lugs 26, 27, 28 and 29 having a curvature conforming to the curvature of the cans to be held and extending outwardly and downwardly from the platen as shown in FIGS. 1 and 3 for the purposes of engaging the chimes of the cans. Leading up to the lugs are loading ramps 30, 31, 32 and 33 for loading the can chimes into the space behind the lugs. The platen 19 further includes a cylindrical stifi'ener 34 with extending stiffening ribs 35 and 36. From the walls of stiffener 34, projections 38 and 39 extend to engage the edge of cans below the top chime. A lift tab 40 may be placed on each platen to facilitate removal of the cans by lifting the platen to allow the top chime to be disengaged.
The platens 18 and 19 are connected together by a connecting link 42 and the inner portion 20 is integral with the link 42 and extensions on opposite sides of the platen 43 so as to form a living hinge when the platen is constructed of polypropylene plastic. This hinge being along line XX shown in FIGS. 2 and 3. This hinge enables the platens to be bent at right angles as shown in phantom lines in FIG. 3 to the can holding position.
The inner portion 20 includes a pair of X-shaped connecting pieces 44 and 45 integrally attached to the platen connecting link 42 and extensions 43 and also includes a middle connecting piece 46.
Carrying handle 22 is provided with generous curves to clear lift tabs 40 and is integrally attached to extensions 43 at areas 47 and 48 to form a pair of living hinges for the handle.
The cantilever bottom support 24 includes a central support beam member 48 extending parallel to the hinge axis XX as shown in FIG. 2. The X-shaped connecting pieces 44 and 45 are integrally hinged to the central support 48 at 49, FIG. 4, forming a living hinge along line YY. In use, the central support 48 and the corresponding cantilever bottom 24 are turned about line YY from the blank position in FIG. 2 to the erected position shown in phantom lines in FIG. 3.
The cantilever bottom support 24 further includes a plurality of individual can cantilever arms 50, 51, 52, 53, 54 and 55. Since these arms are all identical, only cantilever arm 50 will be described in detail. Cantilever arm 50 includes a cylindrical can bottom support 56 and a pair of tapered arms 57 and 58 integral with the cylindrical can bottom support 56 and rigidly and integrally connected with the central support beam 48 by rigid molded connections at areas 60 and 61.
In use, a plurality of cans 12 having chimes 14 may be positioned in the carrier with the bottom 16 of each can being supported on bottom support such as 56 of the individual cantilever arms 50-55. The tops of the can will be held by chimes 14 thereon within lugs on the bottoms of platens 18 and 19. The inner portion 20 will occupy the space between adjacent cans in a row of cans. Handle 22 will normally lie flat against the top of the cans but may be bent upwards as shown in FIG. 1 for carrying the deep-drawn cans as a unitary package.
Although the device has been shown and illustrated as a carrier clip for a six-can package, it is obvious that by suitable modifications such as eliminating one platen 18, X-shaped connecting portion 45 and cantilever supports 54 and 55, the carrier could be adapted to holding four cans. Similarly, it could be expanded to any even number of cans.
Also, it will be obvious that the shape of the cantilever supports 50 may be altered somewhat within the spirit and scope of this invention. For example, if the can bottoms 16 are concaved upward, the cantilever supports may extend into the concavity for supporting the cans from the bottom.
The preferred material used for making the clip would be injection-molded polypropylene plastic due to the nature of the hinging property of this plastic and the fact that it may be formed cold without the need for heating from the full line position shown in FIG. 3 to the dotted line position shown in FIG. 3.
While there have been shown and described and pointed out fundamental novel features of the invention as applied to the preferred embodiment, it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention. It is the intention, therefore, to be limited only as indicated by the scope of the following claims.
