BOTTLE CAP REMOVER AND APPLICATOR Filed Oct. 16, 1946 1 I 8 I CZQ/ Cqzzrzbozb INVENTOR BY AT ORNEY Patented July 11, 1950 UNITED STATES PATENT OFFICE- BOTTLE CAP REMOVER AND APPLICATOR Qharles Capriccio, Corona, N. Y. i Application October 16, 1946, Serial No. 703,543

The invention here disclosed relates to devices for removing bottle caps, and one of the principal objects of the invention. is to provide a device of this character which will remove a bottle cap without injuriously bending the same, and which may be used to conform and reapply the cap in close sealing engagement with the bottle.

Special objects are to provide a tool of this character which will be of relatively simple, inexpensive construction and easily operable both to remove and to reapply the cap.

Other desirable objects and the novel features of construction through which the purposes of the invention are attained are set forth or will appear in the course of the following specification. v

The drawing accompanying and forming part of the specification'illustrates certain practical embodiments of the invention. The structure, however, may be modified and changed as regards the present illustrations, all within the true intent and broad scope of the invention as hereinafter defined and claimed.

Fig. 1 in the drawing is a plan view of the combination tool;

Fig. 2 is a side elevation and part sectional view illustrating the tool as in use in removing a bottle cap;

Fig. 3 is a similar view showing the tool reversed and used in applying a bottle cap;

Figs. 4 and 5 are plan and broken sectional side views, respectively, of a modified form of the invention.

As shown in the several views, the device consists of a lever handle I having a truncated conical socket 8 in one end, of a size and shape to fit down over the flange or skirt portion 9 of a bottle cap I!) and provided, at the side opposite the wider, open end of the socket, with a claw ll projecting into the circular contour of the socket far enough to engage beneath the edge of a cap flange.

The lever 1 may be formed of sheet metal with angularly turned edge flanges l2 stiffening the same, and these flanges may be extended in a circular continuation 13 about the end of the handle and about the circular socket 8.

The conical, cap conforming wall of the socket may be provided by forming the material of the head in a circular bange M inside and substantially coaxial with the rounded edge flange 53 about the end of the lever. This provides a stiff and strong head structure in 1 elatively light gauge metal.

The convergent cap conforming flange I4 is 3 Claims. (Cl. 226-84) shown as smoothly rounded in cross section to apply a smooth rolling flange closing pressure on the cap adapted to gradually close the cap flange about the bead of the bottle neck.

The claw I i may be applied as a, separate piece riveted or otherwise secured at Hi to the lever handle. If a rivet is employed, this may be of square or angular cross section to prevent the claw from twisting on the handle.

To assist in the cap closing action the wall of the socket, at the far end of the lever and at the opposite side from the claw, is shown as having an inwardly extending lip or ridge I6 which will engage beneath the cap flange to serve as a fulcrum when the tool is being used for squeezing the cap down in place on the bottle neck.

For effecting the re-sealing operation the cap may be pressed by hand over the neck of the bottle. It is thus positioned and lightly held ready for application of the closing tool. The fulcrum lug l6 projecting as it does into or within the boundary of the closing socket, practically makes it necessary to apply the tool in the right way, that is, in the downwardly inclined relation indicated by the broken lines in Fig. 3, so as to locate the lug beneath the edge of the cap flange. In so locating the tool that portion of the socket adjacent the lug will apply pressure to the flange and thus start the action of closing the flange into holding engagement with the bead of the bottle neck. Thus, before the lug actually is used for fulcrum purposes the cap is initially gripped to the bottle neck and therefore ready to serve as a fulcrum as the tool is rocked downwardly into the full line position. As the action progresses the cap is gradually and progressively more securely gripped to the bead and consequently is put into condition to serve as a stronger fulcrum as the need for such strength arises. That is, as more pressure is required to accomplish the progressive and final closing action the fulcrum strength is there for application of the required flange closing force.

The claw I I, as appears in Fig. 2, is offset from the flat plane of the lever, at H, sufiiciently to engage beneath the edge of the cap flange when the circular end portion of the lever is rested on top at the far side of the cap.

In such relation this circular and somewhat rounded end portion of the lever at I8 forms an arcuate fulcrum bearing on the rim of the cap. The arcuate extent of engagement and the fact that this fulcrum bears on the reenforced flange portion of the cap, prevents deformation or injury to the cap when lifting force is applied.

The extension of the cap lifting claw into the circular outline of the cap socket, the offset of the claw at I! and the location of this claw opposite the fulcrum lip ll, all contribute to enable the claw to serve as a stop, in the act of applying the cap, Fig. 3, preventing downward movement of the tool beyond that required to fully close the cap flange about the bottle neck. This is important to prevent crushing of the corrugated portion of the flange and to prevent the cap closing socket from rocking down below the edge of the flange where it might catch and interfere with free removal of the tool from the recapped bottle.

Figs. 4 and 5 show how the lifting claw I1 may be made as an integral part of the lever handel by cutting the material for it out .of the top of the handle at l9 and then bending it, as shown, substantially to the conformation of the claw, as previously described.

While the tool may be produced inexpensively in sheet metal, it is contemplated that it may be molded, die cast or otherwise formed.

In this invention injury to the cap is avoided by constructing thetool t0 fulcrum over the flange reenforced rim of the cap at the far side from the liftingclaw, as indicated in Fig. 2. By

such removal the cap is in efiect sprung over the bead of the bottle neck by a simple stretching and more or less uniform expansion of the cap flange.

After such removal the cap is in condition to be easily pressed down over the bead of the bottle neck. Then the tool, reversed to locate the flange contracting socket over the cap, may be pressed down on the cap in the inclined position indicated in broken lines, Fig. 3, .to start the flange closing .actionand to carry the fulcrum ledge 16 down into engagement beneath the edge of the cap flange. When thus located over the cap the lever may be fulcrumed downward about the center E6 to the full line position shown, in which .movement the tapering socket formed by the convergent flange I l gradually and progressively closes the flange of the cap inwardly about the bottle neck. As this action proceeds the capbecomes locked the more securely, enabling heavier pressure to be applied if or as that may become necessary to fully close the securin flange.

In some instances the contraction of the securing flange 'is made more complete by pressing the'lever down over the cap in one position and then rotating the lever to difierent positions over the cap and applying the closing pressure.

Gradual closureof the cap flange over the bead of the bottle neck avoids deformation or injury to the cap, accomplishes a firm, secure, gas-tight seal and leaves the cap in a smooth, symmetrical 1 condition, in which it can be readily removed again, and again be replaced.

The .cap closing socket 8 being open through both sides of the lever, affords full view in both the cap removing and cap applying operations, enabling a person to use the tool 'to'best advantage and permitting a, person to apply finger pressure to the cap when desired, as in the act of placing the tool to start the fian e closin operationthe dotted lineposition in Fig.3.

The flare of the tapered cap contracting socket may be gradually widened and deepened from "the outer, fulcrum side toward the inner, leverage applying side of 'the socket, to facilitate easy engagement and contracting action .over a, more or less opened or spread bottle cap.
