United States Patent Ot'fice 3,055,541 Patented Sept. 25, 1962 3,055,541 COMBINED BEVERAGE CARRIER AND CAP REMOVER Teofil L. Bonkowski, Hollywood, Calif. (1432 Colby St., Los Angeles 25, Calif.) Filed Aug. 31, 1959, Ser. No. 836,994 3 Claims. (Cl. 220-103) The present invention relates generally to the field of capped beverage bottle carriers or packages, and more particularly to a carrier of the collapsible cardboard type that includes an elongate supporting handle which is used not only to transport the packed carrier, but by reinforcing an end portion of the handle which is shaped to define a cap removing device, the handle serves the secondary function of so holding the cap removing device that relative movement can be eifected between it and the bottle from which the cap is to be removed.

In the past few years numerous advances have been made in the packaging of soft drinks and other beverages in capped bottles, particularly those merchandised in carrier ty-pe packages. When disposed in such carriers, the bottles are so arranged as to facilitate easy handling thereof after purchase. In the development of such carriers for capped beverage bottles, one of the paramount considerations has been to devise a collapsible carrier which is adapted to be shipped in quantity and is inexpensive to manufacture whereby it can be given away with the purchase of the bottled beverages contained therein.

Inasmuch as carriers containing a number of capped beverage bottles are (frequently purchased for outings such as picnics, cook-outs on the beach, or for use on camping and fishing trips away from home, the removal of caps from the bottles in such carriers can present an annoying problem unless the purchaser thereof has sufficient foresight to provide himself with a bottle cap remover. A major object of the present invention is to provide a carrier having a handle by which it might not only be moved from place to place, but due to the reinforcement and shape of an end portion of the handle according to a predetermined dimensionally stable configuration a cap removing means is also provided.

Another object of the present invention is to supply an inexpensive collapsible cardboard carrier for transporting a plurality of capped beverage bottles that is attractive in appearance, easy to use, light in weight, and which due to the dual functions served by the handle thereof, will encourage the purchase of beverages con- Another advantage of the invention is that it may be readily incorporated in existing cardboard carriers at very little cost and requires only one additional step in the manufacture thereof.

Still another object of the invention is to provide a preferred and various alternate forms thereof that are of integral one-piece construction, and while primarily adapted to remove caps from bottles, are inoperative for this purpose unless mounted on the handle of a bottle carrier that cooperates therewith to render the preferred and alternate forms of the invention operable.

These and other objects and advantages of the present invention will become apparent from a preferred and certain alternate forms thereof, and from the accompanying drawings in which:

FIGURE 17 is a perspective view of a wire blank; and,

Referring now to the drawing, a conventional carrier A is shown in FIGURE 1 of the type used in carrying a number of bottles B that contain a beverage or other liquid, with the neck portions C thereof removably sealed by caps D which resiliently and frictionally grip the upper circumferential exterior portions thereof.

Carrier A includes an open-topped box 10 usually fabricated from cardboard or multiple-ply heavy sheet paper. Box 10 is defined by a bottom 11,

end walls

12 and 14 and

side walls

16 and 18. The interior of box 10 is subdivided by a longitudinally extending, centrally disposed wall 20 that is parallel to

side walls

16 and 18, and a number of sheet partitions 22 are provided that extend outwardly from both sides of the central wall, and are positioned normal relative thereto. The ends of partitions 22 outward.- ly disposed from central wall 20 are formed with folded, vertically extending flanges 23 which are bonded to adjacent interior surfaces of

side walls

16 and 18, as may best be seen in FIGURE 1. Wall 20 and partitions 2 2 cooperate with the bottom 11,

side walls

16 and 18 and

end walls

12 and 14 of box 10 to define a number of opentopped compartments E, each of which is capable of removably receiving and supporting one bottle B as shown in the drawings.

Carrier A further includes an elongate handle H that may be disposed to project upwardly from the upper longitudinal boundary 28 of wall 20. Often the Wall 20 and handle H are integrally formed from a single sheet of heavy cardboard, multiple-ply cardboard or heavy paper, and in those instances boundary 28 is merely a folding line. However, irrespective of whether it is connected to wall 20, or other portions of the carrier (by means not shown), handle H is initially rectangular in shape and defined by an upper longitudinally extending edge 30 situated a substantial distance above boundary 28 and has identical

parallel end edges

32 and 34. A longitudinally extending opening 36 is formed in handle H, and is sulficiently wide and long to permit the fingers of a persons hand (not shown) to pass therethrough to grip the elongate portion 38 of the handle situated above the opening. Edge 30 may be a folding line if handle H is formed from two sheets of cardboard or heavy paper that are folded one upon the other, with the adjacent surfaces thereof being bonded together by a suitable glue, adhesive or the like.

It will be apparent that the length of handle portion 30, the physical characteristics of the sheet material defining the handle H, and the maximum weight to which carrier A will be subjected when loaded with bottles B, must be so selected and correlated that handle portion 38 does not deform appreciably when subjected to the maximum loading for which the carrier is designed. The end portions 40 and 42 of the handle that extend downwardly to merge with central wall 20 must also possess sutficient strength to support box when loaded with bottles B from handle portion 38.

The preferred form of the invention generally identified by the letter I is shown individually in FIGURE 4, and is also shown in a position affixed to the end portion 42 of handle H in FIGURES 1, 2 and 3. The device I is integrally formed from a single sheet 44 of a corrosion-resistant steel or a steel that is treated or coated to minimize the formation of rust thereon. By conventional stamping and forming methods sheet 44 is shaped to define a side wall 45 having a downwardly and inwardly extending claw 46 outlined on the upper outer portion thereof. The outer extremity of side wall 45 is defined by a concave edge 48 that extends downwardly and inwardly to develop into a straight downwardly and inwardly extending edge 50, which at slightly below the center of side wall 45, develops into a downwardly and outwardly extending edge 52.

Edge 52 terminates in a short, vertical edge 54 that is in substantial vertical alignment with the foremost 46a of claw 46. Side wall 45 is further defined by a lower straight edge 53, an inwardly disposed vertical edge 55, and an upper edge 56 that is parallel to edge 52. By a forming operation sheet 44 is bent to have an elongate lip 58 projecting from edge 56. Also by a forming operation, sheet 44 is so shaped that a continuous flange 60 of curved configuration projects laterally from

edges

46a, 48, 50 and 52 in the same direction as lip 58, as may best be seen in FIGURE 4. Two spaced prongs 60a and 60b project from flange 60, the purpose of which will hereinafter be explained in detail. Sheet 44 is slit near the top and bottom thereof to define two

triangular segments

62 and 64, which are subsequently bent to project laterally therefrom as shown. The end portion 42 of handle H is cut and shaped to conform to the outer edge of claw 46 and

edges

46a, 48, 50, 52 and 54 to permit the device I to be supported thereon as shown in FIGURE 1.

When so supported on handle H, the lip 58 of the pre ferred form of invention I rests on the upper edge 30 and flange 60 extends over and along the curved outer edge of the cut-out end portion 42. When pressure is applied to side wall 45, prongs 62 and 64 penetrate end portion 42 to project therethrough (FIGURE 3), and the projecting prong portions are thereafter bent to extend along the side surface of the end portion 42 opposite that against which side wall 45 abuts. Prongs 66a and 60b are also bent to extend along the side surface of end portion 42 opposite the side against which side wall 45 abuts.

The bent prongs 60a, 60b, 62 and 64 hold the invention I in fixed abutting contact with one surface of the end portion 42 of handle H to reinforce and maintain same in a dimensionally stable position when the cap D is removably engaged by claw 46 and a circumferential edge portion 66 of cap D is in pressure contact with flange 60, as best seen in FIGURE 2. When cap D is removably engaged by claw 46, and a force F is applied to bottle C that tends to rotate same in a counterclockwise direction relative to handle H, to remove cap D from the neck portion C of the bottle, the cap exerts a force F-1 on claw 46 directed outwardly and downwardly from handle H, and a second force F-2 that is directed upwardly and inwardly as shown by the arrow in FIGURE 2 on a portion of the flange 60. The two arrows F-l and F-2 define a turning moment to which the portion of the cardboard material defining end portion 42 of handle H would be subjected were it not for the reinforcing portion 44a of device J. Side wall 45 and claw 46 are sufficiently strong to withstand the turning moment effected by forces F-l and F2 without appreciable deforming or buckling, and as a result the device I can be repeatedly used for removing caps D from bottles B without damage to the device.

Thus it will be seen that reinforcement of handle H by means of invention J not only permits use of the handle in a conventional manner to support the carrier, but the handle H and invention J cooperate to permit the handle to be used for the removal of caps D from bottles B. It is to be particularly noted that while the primary function of the invention J is the removal of cap D from bottles B, it is inoperative for this purpose unless rigidly .aflixed to the end portion 42 of handle H which is especially shaped or cut to permit device I to be mounted thereon and to cooperate therewith in the removal of caps from bottles.

An elongate handle H-l of the same general structure as that of handle H has an end portion 70 on which a first alternate form of the invention K is mounted, as best seen in FIGURE 5. A metal sheet 71 of steel or the like is stamped and formed to define a side wall 72 that includes a downwardly and inwardly extending claw 74 formed on the upper outer portion thereof. Claw 74 has an outer vertical edge 76, the lower portion of which develops into a curved, inwardly extending edge 78. Edge 78 develops into a curved concave edge 80, which in turn merges with a slightly convex downwardly and inwardly curving edge 82. Edge 82 develops into a downwardly and outwardly substantially straight edge 84, which at a point approximately in vertical alignment with edge 76, develops into a straight downwardly extending edge 86. A lower straight edge 88 extends inwardly from edge 86 to develop into an upwardly extending rear edge 90, which in turn develops into an upwardly and inwardly curving edge M.

A portion of sheet 71 above side wall 72 is bent or otherwise formed to define a longitudinally extending web 96, the inner surface of which is slightly wider than the width of the material defining handle H-l. The inner surface of web 96 abuts against the upper edge 97 of handle H-l, as best seen in FIGURE 5. Sheet 71 is also formed to provide an arm 98 that depends downwardly from web 96 in a laterally spaced position relative to side wall 72, and arm 98 defines a second claw 74a which is identical to claw 74 previously described. The inner curved edge of claw 74a merges with an inwardly and upwardly curved edge 100' that terminates at the lower end in an edge 102 which is laterally aligned with edge 94. The outer end 70 of handle H-1 is cut or otherwise formed to present an irregular shape defined by edges 76, 82' and 84' that are laterally alignable with

edges

78, 80, 82 and 84 when the inner surface of web 96 rests on the upper edge 97 of handle H-l.

Side wall 72 (FIGURES 5 and 6) has two identical vertically spaced openings 104 formed therein that are in lateral alignment with bores 106 formed in handle H-l. Rivets 108 project through

bores

104 and 106 to rigidly clamp and hold the first alternate form of the device K on the handle H-1. The device K is used in the same manner as the first form J thereof, previously described, and accordingly the description thereof need not be repeated.

A second alternate form of the invention is shown in FIGURES 7 and 8, identified generally by the notation L, which is adapted to be rigidly aflixed to a flat, upwardly projecting handle H2 of the same structure as handle H described in conjunction with the preferred form of the invention. Invention L, as may be seen in FIGURE 7, is fabricated from a single sheet of rigid metallic material 111 that is stamped and shaped to define a longitudinally extending web 110 having an interior surface slightly wider than the material defining handle H-2. The opposing longitudinal sides of web 110 develop into two identical downwardly extending side walls 112 which are parallel and laterally separated (FIGURE 8). Each of the side walls 112 is partially defined by an inwardly disposed, downwardly extending straight edge 114, and a horizontal outwardly projecting straight lower edge 116 (FIGURE 7). The outer portions of side walls 112 are defined by curved upwardly and inwardly extendingedges 118 that subsequently merge with slightly convex upwardly and outwardly extending edges 120. Edges 120 develop into convex edges 122. Edges 122, together with

edges

124 and 126, serve to define two identical laterally spaced cap engaging claws 128.

End portion 130 of handle H-2 on which device L is mounted is cut or shaped to define

edges

118, 120*, 122, 124 and 126' that are laterally alignable with

edges

118, 120, 122, 124 and 126 which partially define side walls 112 when the second alternate form of the invention is positioned on the handle H-2 as shown in FIG- URE 7. Laterally aligned openings 132 are formed in the two side walls 112 that are also alignable with openings 134 formed in handle H-2. A conventional rivet 136 extends through

openings

132 and 134 to rigidly hold device L on handle I-I-2 in the position shown in FIGURE 7 where it can be used for removing caps D from the neck portions C of bottles B in the same manner employed with the first form of the invention.

The third form of the invention M is adapted to be rigidly affixed to an end portion of a flat, upwardly extending handle H3 which is identical to the handle H previously described, and is shown in FIGURES 9 and 10. The device M is stamped or otherwise integrally formed from a sheet 139 of a metallic material possessing substantial rigidity which defines an elongate web 140 that has a slight lip 142 extending downwardly from one longitudinal side thereof, and a side wall 144 that depends from the other longitudinal side of the web. Side wall 144 is partially defined by a straight downwardly extending, inwardly disposed edge 146 (FIGURE 9), a horizontal outwardly projecting edge 148, and a second downwardly extending edge 150. The lower end of edge 150 develops into a horizontal projecting edge 152, the outer extremity of which joins a vertical edge 154. The upper extremity of edges 154 develops into an upper and inwardly extending edge 156 which at the upper extremity thereof merges with a slightly convex, upwardly and outwardly extending edge 158. The top of edge 158 is connected to a concave edge 160. Edge 160 defines a portion of claw 162, and the balance of the claw is defined by a downwardly and inwardly curved edge 164. A number of identical spaced U-shaped slits 166 are formed in side wall 144 which define integrally formed tabs 168 that are inserted through slits 170 formed in handle H3 to rigidly affix device M to an end portion of handle H-3, as shown in FIGURES 9 and 10. The interior surface of web rests on the upper outer edge portion of handle H3 when invention M is mounted thereon. Before invention M is mounted thereon, an outer portion of handle H-S is cut away to conform with the configuration of

edges

156, 158, and 162 of the third form of the invention and be in lateral alignment therewith.

A fourth alternate form of the invention is shown in perspective in FIGURE 11, generally identified by the letter N, which is adapted to be rigidly aifixed to an end portion of a flat, upwardly extending handle H4 that is of the same construction as that of handle H previously described. Device N is formed from -a single sheet 179 of rigid metal by conventional forming methods. Sheet 1 79 is stamped to define a longitudinally extending web 180 having an inner surface that is slightly wider than the width of handle -H-4. Two identical side walls 182 extend downwardly from opposite longitudinal sides of Web 180. Each side wall 182 is defined by a downwardly extending inner edge 184, a lower horizontal edge 186, and an outer vertical edge 188 which at its upper extremity develops into a downwardly and inwardly ex tending curve 190 that at the inner end thereof merges with a second curve 192 which extends upwardly and out wardly to merge with a third slightly concave edge 194.

The portion of handle H-4 on which device N is mounted is cut away to define

edges

190, 192 and 194 which conform to and are in lateral alignment with corresponding

edges

190, 192 and 194 of side walls 182. Laterally aligned openings are formed in the side walls 182 and the end portion of handle H-4 on which the fourth alternate form of the invention N is mounted (shown in phantom line) through which a rivet v196 projects to hold the device rigidly in place on the end portion of handle H-4 in the position shown in FIGURE 11.

Referring to FIGURES 12 to 16 inclusive, a fifth alternate form of the invention P is shown that is adapted for use with handle H-S of the same general shape as handle H previously described, but which is formed from two sheets of fibrous material such as cardboard or the like, identified by the numerals 200 to 202 that may be connected to one another along a folding line 204 as may be seen in FIGURE 12.

The fifth form of the invention P is preferably die cast from a rigid material such as a suitable metal or a polymerizable resin, and as seen in FIGURES l2 and 13, is partially defined by a vertical inner edge 206, a lower edge 208 and an upper edge 210. To minimize the material required in the fifth alternate form of the invention P the reinforcing wall portion 205 thereof (FIGURE 13) has a triangular opening 212 formed in the lower portion and an elongate downwardly extending opening 214 formed in the upper portion thereof. A continuous flange Q is formed as an integral part of the side wall 205, and as can be seen in FIGURES 1-2 and 13, this flange projects laterally on both sides of the side wall a distance substantially the thickness of one of the

sheets

200 or 202, which when in abutting contact, form handle H-S. Flange Q includes an upper portion 216 that is straight and projects outwardly as an extension of the edge 210, and at the outer extremity thereof curves downwardly and rearwardly to define a second flange portion 218. The lower extremity of flange portion 218 develops into a third flange portion 220 which is concave and subsequently merges with a slightly convex fourth flange portion 222 that at the lower end thereof develops into a downwardly and outwardly extending fifth flange portion 224. Flange portion 224 terminates inwardly a slight distance from an edge 226 formed on side wall 205. Edge 226 is connected to a downwardly extending edge 228 that subsequently merges with the lower edge 208.

The ends of

sheets

200, 202 to which the fifth alternate form of the invention P is aflixed are formed to define edges 216, 218', 220', 222' and 224' as can best be seen in FIGURE 16, that abut against the inner surfaces of

flanges

216, 218, 220, 222 and 224 when invention P is disposed on the end portion of sheet 220 and the sheet 202 is folded thereover to form handle H- as shown in FIGURE 12. Sheet 220 has two filler strips 212a and 214:: rigidly aflixed thereto by glue, adhesive or the like, and is of a size and shape to flt into openings 21 2, 214 respectively when the invention P is positioned on sheet 200. The filler strips are substantially the same thickness as the metal defining the side wall 205. The upper sur face of these filler strips, together with the upper surface of the sheet 200 is coated with an adhesive or bonding agent and sheet 202 is then folded thereover in pressure contact therewith. After the bonding operation has been completed the handle H-S (FIGURE 12) is provided which has the flange Q projecting laterally therefrom to define the fifth form of the invention 'P, but with the major portion of the invention concealed within the confines of the

sheets

200, 202. Should it be desired, a number of spaced prongs 229 may be formed as an integral part of the inwardly disposed portion of the fifth alternate form of the invention, as best seen in FIGURE 13. The prongs 229 are bent outwardly normal relative to the invention, and in this position can be forced through the handle H-S. After the prongs .229 are forced through the handle they are crimped over so that the projecting portions thereof lie against one of the exterior surfaces thereof. Invention P is used in the same manner as the various forms of the invention previously described.

A sixth alternate form of the invention is shown in FIGURE 18 that is forged from the wire blank 232 illustrated in FIGURE 17. 'Blank 232 is formed from soft steel wire, or a wire formed from other forgeable and bendable material. The stock material used in forming blank 232 by a bending operation is straight wire. Each blank is formed from a single piece of wire of predetermined length.

Blank 232 includes a first leg 234 from which a first wire portion 236 projects outwardly from the upper end thereof to develop into an inwardly projecting second portion 238 of hook-shaped configuration. Second portion 238 merges with a third portion 240 of convexconcave configuration that develops into a straight fourth portion 242 from which a fifth portion 244 extends that is parallel to the first portion 236. Fifth portion 244 terminates in a second leg 246 that is in coaxial alignment with first leg 234 but longitudinally spaced therefrom. By forging thereof, the first to fifth portions inclusive of blank 234 is transformed to have a T-shaped transverse cross section. The first to fifth portions inclusive then include

continuous flange portions

236a, 238a, 240a, 242a and 244a from which webs 236b, 238b, 240b, 242b and 24 1b respectively project inwardly. First and second legs 234 and 246 are forged to define flat rectangular plates 234a and 246a respectively.

The webs and plates of the sixth alternate form of the invention are mounted between cut-out end portions of at least two sheets of cardboard or other fibrous material (not shown) that define the handle for a carrier and are glued or otherwise bonded thereto.

Flanges

236a, 238a, 240a, 242a are sufficiently wide to cover the edges of the cut-out end portions. In the formation of the sixth form of the invention, the predetermined length of each piece of wire used and the transverse cross section thereof is that necessary to provide all stock needed in the forging thereof. Operation of the sixth alternate form of the invention is the same as that of the fifth alternate form, and hence need not be described again.

Although the forms of the invention herein shown and described are fully capable of achieving the objects and providing the advantages hereinbefore mentioned, it is to be understood that they are merely illustrative of the presently preferred embodiments thereof and that I do not mean to limit myself to the details of construction herein shown and described other than as defined in the appended claims.
