UNITED 1 STATES PHILIP CASSETTA, 0F PATERSON, NEW JERSEY.

CLOSURE CAP.

Application filed February 26,1924. Serial No. 695,388.

To all whom it may concern:

Be it known that I, PHILIP GASSETTA, a subject of the King of Italy, and resident of Paterson, county of Passaic, and State of New Jersey, have invented certain new and useful Improvements in Closure Caps, of which the following is a specification.

My invention relates to closure caps of the type commonly referred to as bottle caps and which generally speaking are crimped upon the bottle or other receptacle. In removing such caps from the bottle or other receptacle it is necessary to make use of an implement commonly termed an opener. The particular object of the present invention is to provide a cap of the indicated character'with a device whereby said cap may be readily removed from the bottle or other container without requiring. the use of such opener or any other extraneous tool or implement. Other more specific objects will appear from the description hereinafter, and the features of novelty will be pointed out in the claims.

In the accompanying drawing which illustrates an example of the invention without defining its limits, Fig. 1 is a plan view of the improved cap; Fig. 2 is a side view thereof showing the same in position upon the neck of a bottle; Fig. 3 is an enlarged cross-section on the line 3-3 of Fig. 1 andv Fig. 4 is a detail view of the device for removing said cap.

As shown in the drawings the cap itself may be of any customary and well known construction and includes a top 5 and the flange 6, crimped at 7 upon the bottle orother receptacle 8 in any well known way. The top 5 of the cap is provided with a slot 9 which extends outwardly along a radius of the cap and terminates at an annular bead 10 struck up from said top as shown in Figs. 1 and 2. The bead 10 is thus interrupted inregistry with the slot 9 to provide oppositely disposed bearings 10 adapted to accommodate the trunnions 11 of a lever 12 which constitutes the cap removing device. The lever is bent as indicated at 13 to provide a fulcrum section and normally extends over the peripheral edge of the cap and depends therefrom along the receptacle 8 as shown in Fig. '2. A disc is located interiorly of the cap in surface engagement with the top thereof and bridges the slot 9 as illustrated in Fig. 3. The disc referred to may comprise the customary packing 14 usually found in caps of the indicated type, or it may be a metallic plate 15 combined with said packing and shaped to fit the interior of the cap as shown in Fig. 3.

The cap is applied to the bottle or other receptacle 8 in the usual way, either by hand or by suitable machinery; in the latter case the bead 10 receives the thrust of the capping machine and distributes the same uniformly over said cap so that the latter is evenly applied to the bottle or other receptacle which it is intended to close; at the same time the annular bead neutralizes the crushing force of said mechanism and prevents the same from injuring or destroying the bearings 10".

When it is desired to remove the cap the I lever 12 is pivotally moved from the posi-. tion indicated by solid lines in Fig. 3 to the dotted line position therein in which said lever extends upwardly from the cap ready for use in prying the latter loose from the bottle or other receptacle 8. That is to say the lever 12 when brought to the dotted line position in Fig. 3 shifts the fulcrum section 13 into engagement with that part of the disc 15 or its equivalent, which lies in registry with the slot 9 and thereby becomes a lever of the first class. If the lever 12, when in the dotted line position, is forced in the direction of the arrow in Fig. 3 it will fulcrum upon the section 13 and disc 15 or its equivalent and accordingly exert a lifting leverage upon the pivotal connection or specifically upon the bearings 10 through the medium of the trunnions 11. In this way the cap is easily removed from the bottle 8 or other receptacle by means of said lever and without requiring the use of any other tool or implement.

In its normal position the lever 12 occupies an inconspicuous position adjacent to the bottle or other receptacle 8, in which it does not interfere with the normal'handling of the bottle or with the placing thereof in boxes or other carriers. The annular head 10 and those portions of the lever which normally are in a position above the cap, present' no interference to the manipulation of a bottle or other container 8 in any conventional manner. The device is simple in construction and eflicient in operation and being connected with the cap is always L 15 or its equivalent available for use when required. The slot 9 in addition to its other functions permits the trunnions 11 to be easily inserted into the bearings 10*; this may be readily accomplished by placing the trunnions lengthwise insaid slot and then by a quarter turn of the lever 12 passing them beneath and into the bearings 10 While the device is primarily intended for use in connection with bottle caps it is obviously capable of incorporation in caps intended as closures for other receptacles.

In the preferred procedure the cap is applied to the bottle in the customary manner and t-he lever 12 is combined therewith, in

the'manner previously set forth, after the cap is in position on said bottle. The arrangement is always such, thatthe fulcrum section 13 of'the lever 12 bears upon that part of the disc 15 or its equivalent which the bottle neck.

The latter thus acts to resist the forceexerted upon said fulcrum section 13, in the act of removing the cap, and thereby prevents the inward deformation of the disc and at the same time provides a firmfoundationfor the fulcrum of the lever:

Various changes in the specific form shown andv described may be made within the scope of the from the spirit of I claim: I H I 1 k 1.
