Claims. (CI. 220—102)

This invention is in the field of carrying cases or containers for pop bottles and more specifically relates to what is commonly referred to as a six-pack.

A primary object of the invention is a bottle carrying case which, while inexpensive, will have much greater trip life.

Another object is a carrying case for bottles and the like which is made of a combination of plastic and metal, such as aluminum.

Another object is a six-pack carrying case which can be sterilized -and reused many times.

Another object is a carrying case for bottles with a combination handle and divider structure.

Another object is a six-pack carrying case which will not attract vermin and will stand up to weather.

Another object is a carrying case which will automatically interlock with the tops of the bottles in a like case below it.

Another object is a carrying case which may be easily repaired.

Another object is a lightweight carrying case which will not cause the bottles to scratch the hand of the person carrying it.

Other objects will appear from time to time in the ensuing specification and drawings in -which:

FIGURE 1 is a perspective of my six-pack, with the bottles shown in phantom;

FIGURE 2 is a top view of the base and handle structure with the sides broken away;

FIGURE 3 is a side view of FIGURE 2;

FIGURE 4 is a bottom view of the base shown in FIGURE 2; and

FIGURE 5 is a partial side view of a variant form.

In FIGURE 1, the carrying case is shown as including a base 10 with sides 12 and a centrally disposed handle structure 14. As shown best in FIGURES 2 and 4, the base is made up of a plurality of interconnected integral ribs or slats 16 which intersect generally at 90° or perpendicularly -and are disposed roughly at 45° to the lateral and longitudinal. The sides of the grill-like or gridlike -base, on all four sides, is closed by a continuous rim 18 but is offset inwardly on the longitudinal sides, at 20, and also on the ends or lateral sides at 22.

In effect, the sides follow certain ribs inwardly, as at 24, to a certain cross rib 26, then resume their longitudinal or lateral direction from the point of intersection. The same is true of the ends. The base thus takes on the appearance of a somewhat smaller rectangular shape with ears projecting outwardly at 45° at each corner. The corners are chamfered at approximately 45 at 28, and a post 30 rises from each chamfer across the corner to a given height.

The entire base is preferably made of plastic and is molded integrally. The corner posts 30 are also plastic and are integral with the base and molded at the same time.

Considering one post in detail since the others may be the same, the post has offset wings 34 projecting at an angle -from each side at the upper end of the post and extending laterally and longitudinally. Each wing is provided -with a step or offset 36 on its outer face and a strap 38, preferably o-f aluminum, extends into this step and has double tabs 40 which are bent at right angles inwardly to pass through double slots 42 in the wing 'and then it is turned back and crimped at 44 in FIGURE 1. The tabs 40 are one above the other and closely spaced, as are the slots 42. Thus, instead of a single opening from top to bottom which would pull 5 open under tension, double slots are provided or a single slot with a cross tie, at 43, to prevent separation. The strap is preferably the same thickness as the step so that the outer surface of the strap will flow smoothly into the outer surface of the full thickness wing. As shown in FIGURE 1, I use two straps disposed longitudinally on the long sides and two short straps disposed laterally across the ends with a connection at all corners between the ends of the straps and the wings of the comer posts being the same. It should also be noted that the strap, 15 in height, is about the same as the wing height so that the straps and wings, in effect, form a uniform continuation around the carrying case.

The handle 14 includes two upstanding posts 46 with a looped over U-shaped handle 48 connected across the 2Q top. The handle 48 is T-shaped in cross section with a back strap 50 crossing an outstanding rib 52. This same T-shaped cross section is in the posts 46 so that the handle, in effect, forms a smooth continuation of the posts.

Ribs 54 project upwardly from the base inside of the carrying case and include six outstanding feet 56 which are rounded over at their ends, at 58, where the ribs stop at the sides of the base. The center rib 60 extends between and connects the bottom of the feet 56. It should also be noted that the ribs 54 in the bottom extend laterally and longitudinally and connect to the diagonal slats 16 at their points of intersection, as shown in -FIGURE 4, providing a rigid connection between the handle and base.

_3g .Divider arms 62 extend outwardly from the handle with their upper edges 64 in the same general plane as the top of the straps and side posts. So the divider structure is roughly on the same level as the surrounding straps. The dividers are rounded at their ends, at 66, and ter40 minate in spaced relation, as shown in FIGURE 1, from the straps. This is to say that the dividers stick out on all four sides toward the side straps, but only go a little over half way, and then stop. A center strap 68 connects the top of the feet between the arms 62.

₄5 It will be noted in FIGURE 2 that the divider arms are vertically aligned with the ribs and together define vertically disposed bottle pockets with the surrounding side structure, one at each corner and two in between on the sides, making a total of six. The spacing is such that 5θ the bottle in a corner pocket will be held between an end arm and a side arm about half way up and the base of the bottle will be held between an end rib and a side rib. In a sense the bottle will be cradled between the ribs and arms and backed up by the corner post and its wings. The 55 bottles in the middle on each side will have side arms both ahead of and behind them and side ribs below with a strap on the side holding them in.

. As shown in FIGURE 4, the bottom of the base is provided with a plurality of integral projections 70 which 00 surround the center of each bottle pocket and are disposed in .groups. The projections are disposed on a circle which will surround the cap of a bottle in a similar case below it. This is to say that when two cases, filled with bottles, are stacked one on top of the other, the projec_6g tions on the bottom of the upper case will just fit around the caps on the bottles in the lower case. This provides a degree of interlock which will prevent the top case from sliding off when jostled or vibrated in transportation or otherwise and will also hold the case up, somewhat, when it rests on a flat surface, such as the floor.

In FIGURE 5, I have shown a variant form in which the handle and divider structure is disconnectable from the base. The upper portion of the legs is each separated

3,045,863 from a stud or post 72 which has a fastening tab 74 with a hole 76 to receive a button 78 positioned on an offset 80 in the crosspiece of the T-shaped cross section. The joint could be located anywhere between the dividers, such as at 62 in FIGURE 3, and the ribs in the bottom, such as at 56 in FIGURE 3. Having the handle and divider structure separable from the rest of the case may simplify storage and shipment after manufacture.

The use, operation and function of my invention are as follows:

The base and central handle and divider structure are made integrally and entirely of plastic. The corner posts are also integral with the base and are made of plastic. The straps on all four sides, two long and two short, are preferably of metal, in this case aluminum. The interior is totally open on all four sides with a grill or gridlike bottom, so that the unit may be completely sterilized and thoroughly cleaned after each trip. Since the case is entirely of plastic and aluminum, there is nothing to attract vermin and it will not fall apart when it becomes wet due to rain or otherwise. The case has a long trip life and can be used over and over.

The upstanding handle and divider structure is not connected to the sides and is somewhat flexible, thus providing a cushion type ride for the bottles. The dimensioning is such that the bottles rise well above the handle, which can be easily grasped by slipping a hand down between the two center side bottles. The over-all structure is sufficiently flexible that it will withstand and give with impact, and will not break or rupture.

While I have shown the handle as T-shaped on top, it might be flattened or somewhat solid. I prefer that the sides have a T-shaped cross section, however, for strength.

Another important aspect of the invention is that the metal straps or strips may be replaced easily. Thus, if a particular strap is torn, bent or otherwise damaged, the bottler may carry a reserve supply of straps, one of which may be easily substituted, and the case may be reused indefinitely.

Another advantage of this case is that it will fit in present automatic filling equipment. This is to say that the posts, straps, etc. are all thin and, in a sense, the over-all dimensions of the case may be the same as or no more than an equivalent paper unit.

One of the big advantages of the freely upstanding handle and divider structure is that when the carton is full of bottles and the user or purchaser picks it up by slipping his hand between the two center bottles and under the top cross strap of the upper handle structure, the back of his hand and knuckles will not be scratched by the bottle caps. In a normal case where the dividers are attached to the sides, the case will be laterally rigid and the caps of the center bottles will scratch the back of a person’s hand. But in this case the side straps 38 are sufficiently flexible and are not connected directly to the dividers 62 such that the center bottles will flex outwardly. In essence, there is no rigid connection, direct or indirect, between the upper portions of the handles and either of the sides.

In molding, the legs 30 may lie out flat in the same plane as the grid base. Thus, the molding dies will be greatly simplified. For assembly, the four legs at the corners would be turned up to the positions shown and then the bands connected. At the same time, the upper part of each leg 30 may be rounded somewhat, instead of flat and at 45°, as shown.

Another important feature is that the handle structure with the reinforcing ribs 56 and 60 at the bottom are integrally joined to the grid base where the bottle load is the greatest. The webbing or ribs in the bottom tie the over-all grill structure together and the bottle load will be fully carried by the handle. The grid bottom, in addition to providing for cleaning and sterilizing, saves a substantial amount of plastic.

It should be noted in FIGURE 3 that the handle, above the arms 62, diverges somewhat and is spaced a maxi4 mum at the top so that the user can easily get his hand under the cross strap.

In the arrangement shown, when the base, handle and posts are made integrally and entirely of plastic with lightweight metal straps around the sides, for example of aluminum, the over-all case will weigh about 4 ounces which is slightly less than an equivalent paper carrying case.

While I have shown and described the preferred form of my invention, it should be understood that suitable additional modifications, changes, substitutions and alterations may be made without departing from the invention’s fundamental theme. I, therefore, wish that the invention be unrestricted, except as by the appended claims.
