BOTTLE-CAP.

Specification of Letters Patent.

Patented Feb. 19, 1918.

Application filed May 4, 1917. Serial No. 166,392.

.To all whom it may concern:

Be it known that I, MARY L. EVANS. a subject of the King of Great Britain, residing at Calgary, in the Province of Alberta and Dcminion of Canada, have invented certain new and useful Improvements in Bottle- Caps, of which the following is a specification.

This invention relates to bottle caps, and the primary object of the invention is to provide an easily removable cap for use with all kinds of glass containers and receptacles such as milk bottles, fruit jars, preserve jars and the like, whereby the open end of the neck of the receptacle or container may be closed when a portion of the contents has been removed.

Another object of the invention is the provisions of a bottle cap constructed to be easily attached to the neck of the bottle and engageable with the interior thereof, so that an air-tight contact is made to prevent air'frorn gaining access to the bottle thus preserving the contents of the bottle.

A further object of this invention is the provision of a bottle cap which consists of comparatively few parts and is simple in construction, but durable and well adapted to withstand the rough usage to which devices of this character are ordinarily subjected.

For a full description of the invention and the advantages and merits thereof, reference is to be had to the following description and the accompanying drawings, wherein is illustrated the preferred form of my invention, in which;

Figure 1 is a fragmentary section through a bottle provided with a bottle cap constructed in accordance with my invention.

Fig. 2 is a detail section of the bottle cap removed from the bottle.

Fig. 3 is a section on the line 3-3 of Fig. 2.

Fig. Fig. 2.

Referring to the drawing, wherein is illustrated the preferred form of my invention, and in which like numerals of reference indicate corresponding parts throughout the several views, the bottle A is provided with the usual neck in which may be received any suitable closure. The present cap includes the provision of a sleeve 1 constructed of suitable light metal, and having both ends closed by the walls 2 and :3, The wall. 2 is 1 is a section on the line 4-1 of extended outwardly beyond the sleeve 1 to provide an annular flange 4, engageable with the top open end of the bottle neck for limiting the inward movement of the cap.

An annular channel 5 is formed in the sleeve by pressing inwardly a portion of the sleeve intermediate its ends thus forming a channel substantially as wide as it is deep. The formation of this channel provides the interior annular recesses 6 and 7 at opposite ends of the sleeve.

The top 8 is provided with apertures 8 through which the ends of a length of wire 9 are extended. The ends of the wire are curved inwardly of the annular recess 7, and engaged with the inner wall of the sleeve as shown clearly in Figs. 1 and 2. These inwardly bent portions of the wire prevent the withdrawal of the wire from the sleeve, and thereby provide a handle for permitting extraction of the cap from the neck of the bottle.

An annular resilient gasket 10 is mounted in the channel 5, and is of a thickness slightly less than the width of the channel, so that movement of the gasket in the channel is formed. The outer marginal edge of the gasket is beveled as shown by Figs. 2 and 3 0f the drawing, thus providing a wedging action when the cap is forced into the bottle neck, and facilitating the compressing of the gasket for providing an airtight joint to exclude air from the interior of the bottle. In operation it is merely necessary to force the cap into the neck, the gasket wedging itself into position and tightly engaging the inner surface of the opening in the neck. The handle 9 will facilitate the easy extraction of the cap when desired.

From the foregoing it will be observed that a very simple and durable bottle cap has been provided. the details of which embody the preferred form. I desire it to be understood, however, that slight changes in the minor details of construction may be made without departing from the spirit of the invention or the scope of the claims hereunto appended.

I claim:

1. A bottle stopper comprising a sleeve having a central annular channel pressed inwardly of the sleeve and forming interior annular recesses at each end of the sleeve. a resilient gasket received in the said channel, both ends of the said sleeve being closed, an

annular flange formed by the extended edge of one of the said closed ends, the said closed end having openings formed therein, and a wire handle extended through the openings and received in one of the said recesses.

2. A bottle stopper comprising a sleeve having a central annular channel pressed in- Wardly of the sleeve and forming interior annular recesses at each end of the sleeve, a resilient gasket received in the said channel, both ends of the said sleeve being closed, an annular flange formed by the extended edge of one of the said closed ends, the said closed end having openings formed therein, a Wire handle extended through the openings and received in one of the said recesses, the ends of the said wire handle being bent and engaged with the wall of the recess to prevent the Withdrawal of the said handle.

3. A bottle stopper comprising a, sleeve having a central annular channel pressed in Wardly from the exterior of the sleeve at a point approximately intermediate its ends, a resilient gasket received in the said channel and slightly thinner than the Width of the said channel, both ends of the said sleeve being closed, one ofthe said closed ends having openings formed therein, the said channel forming annular recesses in the upper and lower ends of the sleeves, a Wire'handle eX- tended through the openings and received in the uppermost recess, the ends of the said Wire handle being bent and engaged with the Wall of the uppermost recess to prevent Withdrawal of the said handle, and an annular extension formed on the uppermost closed end of the sleeve.

In testimony whereof I a-fiix my signature.

MARY EVANS.
