BOTTLE CAP.

Application led November 15, 1926.l Serial O. 148,564.

This invention relates to the class of bottles and jars and pertains particularly to a closure element for such.

The primary object of this invention is to provide, in a manner as hereinafter set forth,

a bottle cap of the crimped type so constructed that the same may be easily and quickly removed without the use of a bottle opener or other contrivance, other than the finger.

Another object of the invention is to provide, in a manner as hereinafter set forth, a bottle cap so constructed that after having been once used, it cannot again be used in the same capacity.

Still another object of the invention is to provide, in a manner as hereinafter set forth, a bottle cap which will permanently and tightly close a bottle, inexpensive to manufacture, and adapted to be easily and quickly removed as above described.

Other objects and advantages of the invenir tion will become apparent as the description progresses, and the invention will be best unv derstood from a consideration of the following detailed description taken in connection with the accompanying drawings forming a part of this specification, with the understanding, however, that the invention is not confined to -any strict conformity with the showing of the drawings but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as eX- pressed in the appended claim.

In the drawings:

Figure 1 shows the upper portion of a bottle having a cap of the type embodying this invention secured thereto.

Figure 2 is a side elevational view of the same character as the Figure l, with the bottle top having been given a quarter turn.

Figure 3 is a transverse section through the cap embody lg this invention, or upon line 3 3 of Figure l.

Figure l is a transverse section through the cap taken at right angles to the section shown in Figure 3, or upon line 4 4 of Figure 2.

Figure 5 is a top plan View of the cap member, and

Figure 6 is a side elevation of the cap and the upper portion of a bottle, showing the manner in which the cap is broken when being removed from the bottle.

Referring now to the drawings in detail wherein like numerals of reference are used to indicate corresponding parts throughout the several views, the Figure 1 indicates the upper portion of a bottle of the character commonly known as a pop bottle. It is,

of course, to be understod that these caps can be used upon other bottles such as 'beer bottles, catsup bottles or the like.

The cap embodying this invention comprises the usual disc portion2 having the downturned annular crimped skirt 3. The skirt 3 of the cap is provided at diametrically opposite points with a slot 4 which extends from the lower edge of this skirt to the upper portion thereof or the point of oinder between the skirt and the disc body 2.

One of the skirt portions set up by forming the slot 4 has extending from the free edge thereof preferably midway between the ends formed by the slot a downwardly extending tongue 5, the free lower edge of which is turned outwardly as indicated at 6.

The usual cork disc 7 is arranged Within the cap against the under side of the disc 2, which cork as is well known is forced down upon the lip of the bottle mouth and .serves to set up a leak proof closure in association with the cap.

As is well known, these caps, when placed upon the bottle mouth have the skirt portion 3 uncrimped and the capping machine when acting upon the skirt to crimp the same into an annular recess formed about the bottle mouth thus clamping the skirt securely to the bottle. The provision of the slot 4 in the skirt does not in anyway interfere with the clamping action of the skirt upon bottle mouth, and as will be readily understood from reference to Figure 3 of the drawing, when it is desired to remove the cap, a splitting of the skirt enables one to break the cap transversely by the pulling upwardly upon the tongue 5.

As will be readily seen the cap of the type embodying this invention may be readily removed from a bottle without the employment of usual bottle opener, it only being necessary to place the thumb nail beneath the tongue 5 and pull outwardly thereon.

As above explained the disc 2 will bend or break on a line extending between the upper ends of the slot 4 thus enablino the cap to be removed from the bottle mout 1.

Having thus described my invention, what I claim is:

5 As a new article of manufacture, a bottle cap comprising a disc shaped top wall, a depending annular skirt formed on said top wall having diametrically disposed slits ex? tending from the free lower edge of the skirt EDWARD A. WYGONIK.
