11 Claims, 6 Drawing Figures COMBINATION HOUSEHOLD IMPLEMENT This invention relates to a combination implement. Basically, the device is a can opener comprising a rigid strip of metal having an endbent upon itself and providing a tapered blade for cutting a pouring opening in a container top, the body strip having an air hole punch located intermediate the ends, and the body of the implement in general being adapted to overlie a can being punched so that it will swing over and downwardly toward the can with downward pressure exerted by the hand of the user. This distinguishes from conventional can piercing devices in that the fulcrum is so arranged that the container must be grasped in one hand while the implement is hooked under the bead of the top and operated with an upward pull by the user. This difference greatly simplifies the can punching operation because it utilizes downward pressure supplied by part of the weight of the user and a can can be pierced to provide a pouring opening and an air inlet opening with one hand instead of the two hands required with devices presently available.

Another object of the invention is to provide a device of this type with means for hooking beneath a finger ring on the hand of the user. Thus, the implement need not be tightly gripped when it is being used and in food and beverage dispensing operations, where. a large number of containers are being opened in a short period of time, the operation can be accomplished quickly and easily.

Additionally, it is an object to provide an implement made up of a rigid strip of metal wherein other features are incorporated for different functions, such asrotating nuts and bolts, inserting and removing screws, bullnosing or reducing the comers on pieces of wood, removing crimped bottle caps, and cutting string or the like, all of these features being incorporated in the The above and other objects will more fully appear from the following description in connection with the accompanying drawing.

FIG. 1. is a perspective view of an embodiment of the invention. r I

FIG. 2 is a side elevational view of the upper portion of a .metal container, portions of which are broken away and showing two positions ofthe implement relative thereto in broken. and full lines;

FIG. 3 is-an elevation illustrating its use as a crimped cap remover;

FIG. 4 is a perspective view of the implement and the upper portion of a container with the implement in position to punch a single hole in the side of the container P;

FIG. 5 is a fragmentary elevation show-ing the implement used as a screw driver;

FIG. 6 is a perspective view of a portion of the implement showing its use as a bull-noser or corner rounder for pieces of wood.v

The device illustrated comprises a body 8 comprisin a strip of rigid metal having throughout most of its length a convex upper side 10 and a concave underside 12. One end portion of the body 8 is bent downwardly at 14 and inwardly at 16, and the extreme end thereof is tapered and sharpened to provide a cutting blade 18 of the type conventionally used for piercing can tops to provide pouring openings, such as the opening 20 in the top of the container 22 in FIG. 2. Adjacent the upper portion of the blade 18 a lug 24 is struck outwardly from the body or strip 8 to hook beneath the bead 26 around the top of thecan or container 22.

When the lug 24 is hooked under the bead 26 in approximately the broken line position of FIG. 2, the blade 18 overlies the can top and when the implement is swung about the lug 24 as a fulcrum in a clockwise direction as viewed in FIG. 2, the blade 18 will engage and pierce the top of the can with a forward and downward pressure of the hand of the user.

Intermediate the ends of the body 8 is an air hole punch 28 in the form of a tongue struck from the body of the implement. It extends downwardly as illustrated and as the implement is rocked over and downwardly the punch 28 will punch an air hole in the top of the can. The punch, upwardly from its lower end, is shouldered as at 30. In normal operation the punch will puncture the can top until the shoulders 30 at either side of the punch engage the metal of the top so that the shoulders provide what might be termed a depth gauge. Clearly, the air hole will only be the size of the punch between the lower end and the shoulders 30. However, if a larger hold is desired, additional hand pressure on the implement will force the shoulders 30 through the can top and-the additional width above th shoulders will enlarge the hole.

When used as a can opener the can can be held in the hand by placing the curved portions 14 with knurled surfaces 32 against the base of the thumb with the concave-convex body extending toward the finger tips. The length of the body from the curved portion 14 to the opposite end is preferably such that theends of the tingers can curl over the end of. the body slightly to grip the implement between the finger ends and the base of g the thumb. In this position, the hand is slightly flexed to conform to the curvature of the major portion of the implement. When so held, the lug 24 canbe placed under the head 26 of the can top and the implement rocked with downward pressure from the broken line position of FIG. 2 to the full line position thereof. Be-

7 cause of this structure, the user can hold the implement in one hand and pierce a can top without requiring that the can or other container be securely held by the other conventional can piercing dehand', I provide a prong 34 which is struck from the air hole piercing tongue 28, as best indicated in FIG. 3, the prong leaving an aperture 36 in the base of the material comprising the tongue. Prong 34 is bent forwardly, and as shown in FIG. 2, it can fit in a finger ring 38 on a finger 40 on the hand which manipulates the implement. The ring engaging prong 34 is a particular advantage where a number of containers are to be opened in quick succession. It will hold the implement against the hand even though the ends of the implement are not tightly gripped as explained previously.

When the tongue 28 is struck from the body 8, it leaves an aperture 42. The side edges of this aperture I provide with opposed parallel edges 44, 46,48 and 50. The pairs of opposed edges are different distances apart and provide wrench means for turning different sizes of threaded nuts and bolts. One or more individual sized apertures 52, hexagonal or square in shape, can also be provided to permit the implement to be used as a wrench. One end of the body is provided with a partially sharpened extension 54 which can be used as a screw driver, as illustrated in H6. 5.

Extending inwardly from one side of the body, is a notch 56 defined by a long side 58 lying diagonal to the side edge 60. The other side of the notch is defined by a short side 62 defining a book 64. Intermediate the ends of the long side 58 of notch 56 is a projection 66 formed by making the long side 58 slightly angular, the projection 66 providing a fulcrum when the notched portion is slipped over a crimped bottle top as shown in FIG. 3. Initial downward pressure on the cap with the hook 64 beneath the edge will permit the projection 66 to serve as a fulcrum upon which the implement is tilted to begin the unseating of the cap. A second fulcrum is provided at 68 for the final removal.

Formed in the curved portion 14 of the body is an aperture 70 defined by a flared wall portion 72 in the thickness of the rigid metal strip comprising the body 8. The inner end of the aperture 70 is defined by a sharpened edge 74. This sharpened end, as shown in FIG. 6, serves as a bull-noser for takingoff the sharp edges of a piece of wood. Here again, as in the case of the wrench portions and the crimped cap removing portion, all the structure for providing these functions is located within the thickness of the body 8 so that these features will not interfere with the operation of the device as a can piercing implement.

The curvature of the body 8 is so related to the cutting blade 18 and fulcrum lug 24 that the pouring opening 20 is formed by blade 18 by a'rolling or tilting and pressing movement of the hand and that most of the pouring opening 20 is completed before the punch 28 encounters the can top. When this does occur, the tilting or swinging momentum has increased and the action of the punch 28 is produced with less effort because resistance of the can top to the blade 18 has been greatly diminished.

The curvature of the body 8 is such that the wrench portions 42, 44, 46, 48, S'and 52 can be used conveniently, since the body8 curves away in opposite directions from the point or plane of location of a nut to be turned.

. It should be noted that the bottom of the notch 56 which defines the crimped cap remover is defined by a sharpened edge 74 which can serve to cut string or the like. This cutter is also noted to lie within the thickness of the strip of metal defining the body 8.

It should be noted that the screw driver feature 54 can also be put to different uses, such as the prying of lids from paint cans and similar containers having crimped tops, and for removing the lids of some food containers made of glass and having priable metal tops.

lt should be understood that various-changes can be made in the form, details, arrangement and proportions of the various elements without departing from the spirit of the invention.
