CAI-CLOSURE.

Specification of Letters Patent. I Patented Sept. 20, 1921.

Application iiied March 21, 1918. Serial No. 228,752.

To all'whomit'may concern:

Be it known that I, WALTER C. FOELL, a citizen of the United States, residing at Waterbury, in the county of New .Haven and State of Connecticut, have invented certain new and useful Improvements in a Cap-, Closure, of which the following is a specification.

This invention relates to improvements in closures for bottles and jars and it is the principal object ofv the Invention to provide a novel form of cap closure adapted to be applied over the mouths of bottles and other receptacles and secured by crimping or like modes of distortion to the necks of the same and which, when desired, can be quickly removed therefrom but when engaged with the bottle will serve as a'highly efiicient and positive seal therefor.

' Other objects will be in part obvious and in art pointed out hereinafter.

he improvements in the details and ar-' rangement of parts will be apparent from an inspection of the accompanying drawings, in connection with the specific description hereinafter contained, and wherein thepreferred embodiment of the invention is disclosed for the purpose of imparting a full understanding of the same.

In the drawings:

Figure 1 is a side elevation of the improved cap closure as applied to a portion of a bottle neck,

Fig. 2 is a vertical section therethrough,

Fig. 3 is a vertical section through the cap showing the relative arrangement of the same and the; closure disk before the lower portion thereof is crimped, and

Fig. 4 is a fragmentary horizontal section through a portion of the cap and thebottle neck showing the same crimped.

Having more particular reference to the drawings, in connection with which like reference characters will designate-corresponding parts throughout the several views-of the .drawings, 1 representsthe neck of the bottle, 2 the usual curved shoulder formed thereon directly'below the mouth of the same and 3 the curved beading formed upon the upper end of the same adjhcent its mouth; this construction being common in connection withthe-manufacture of bottles for containing different forms of beverages and the like.

The improved closure comprises a cap designated in its entirety by the numeral 4,

the intermediate portion of the annular sides thereof being crimped to form an annular inwardly extending rib 5, while the lower portion of the cap sides are adapted to be connected or engaged over the curved beading 3 by crimping as indicated at 6 or I by other suitable forms of distortion.

A sealing disk 7 is provided and is adapted to be arran d over the mouth of the bottle neck 1; t e marginal portion of said disk extending for a distance onto the curved heading 3 in order that the slanting face of the rib 5 formed in the annular sides mouth when the lower portion of said cap is crimped or otherwise distorted as at 6 in order to insure engagement between the same and said curved beading 3. With the cap thus applied over the bottle neck mouth, it will be readily understood that the bottle will be efliciently and positively sealed, thus, permitting the contents of the same to be effectually preserved.

Attention is directed to the fact, that the upper portion of the closure cap 4 is extended for a distance above the bottle neck, as clearly shown in the Figs. 1 and 2. Hence, when it'is desired to disengage the closure cap from the bottle neck, it is only necessar to sharply or abruptly tap the top of the .c osure cap, thereby forcing the same downwardly and causin an outward riding engagement of the slanting face of the rib 5 with the disk and the beaded portion 3 and to ride over the curved shoulder 3 and as a' consequence, the crimped portion 6 thereof will be spread sufliciently to allow the closure cap to be freely withdrawn from engagement with the bottle neck. The circular side wall of the cap 4 lying between the rib 5 and closed end is of uniform diameter throughout thus providing a rightangular corner which is disposed so prominently that it ma be conveniently struck against a wall or ot er object 'to' remove the cap from the bottle.

From the fore oing, it will be understood by persons skille in the art that I have provided an exceedinglly cheap, sim 1e and eflicient form of bott e closure an one which by reason of its construction may be quickly and readily disengaged from a bottle neck, thus, saving considerable time and quite often, reventing the wasting of the contents oi the bottle or the fracturing of the bottle neck in attempts to remove the closure a ward movement of the same over said neck.

Further, the cap may be formed of any suitable material, such as sheet metal or the like, "such as conditions or preference may dictate. As'indicated, I do notwish to be understood as confinlng' the invention to the par- ,ticular' embodiment chosenfor illustration -herein, 'nor to the exact construction, ar-

' rangement and adaption of parts shown am:I described, but I reserve the right to ma fall within the spirit and scope of the invention. I

I claim:

The combination with a bottle having an outwardly directed annular bead at its mouth and an annular enlargement next the bead, of a cap comprising a cylindrical body closed at the outer end and with an inwardly directed rib intermediate the ends, the portion of said cap between the rib and its open end adapted to be crimped into the space between the bead and the enlargement to lock the cap in position, the cap being detachable by pressure applied to the ca longitudinally of the bottle to-force the ri over the bead and the crimped portion over the enlargement.

V In testimony whereof, I aflix my signature hereto.
