To all whom it nuzy concern:

Be it known that 1, ROBERT FLANIGAN, of

the city of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Closures for Bottles; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon.

Thisiuvention relates to that class .of closures adapted more especially for use on botscribed, and pointed out specifically in the ap- .pended claims.

It has been heretofore proposed to employ a bottle having a suitable lip-flange or annular enlargement around the mouth with a cap adapted to fit over the mouth of said bottle and around the enlargement, the downwardlyextending portion of the cap being crimped to form inwardly-extending projections for cooperation with the enlargement to hold the cap in place and a disk of sealing-material, such as cork, being placed within the cap to form an air-tight closure. Such devices in actualuse have been found ineflicient-, the

difliculties being due to the fact that there is little if any latitude for inequalities in the conformation of the bottle-mouth and enlargement, thus making it impossible to fit the closure accurately, especially as it is found to be practically impossible to obtain bottles which are strictly accurate and uniform in' their conformation. A further objection to such caps is that they necessitate the employment of a special tool for, applying the caps in place by bending the flange inwardly and clamping the sain'e on the bottle-neck.

One 0 the main objects of my invention is to overcome this ODjOGGlOIl' and, further,-to

provide for the use of the closure upon bottles'difiering slightly in size.

Referring to the accompanying drawings, 7

Figure 1 is a vertical section through a bottle and closure constructed in accordance with my invention. Fig. 2 is an enlarged detail section through the closure itself; Fig. 3, a detail perspective showing the bead slitted to provide for a wider range of elasticity-than can be secured with the construction illus 'trated in Figs. 1 and 2; and Fig. '4, a perspective view of a closure, showing the bead and flange cut vertically to provide a wider range of elasticity than can be secured with the constructionillustrated in Fig. 3.

Like letters of reference in the several figurs indicate the same parts. I

- The bottle A in the accompanying drawin'gs, it is obvious, maybe of any of the ordinary or of any preferred form, it only being essentialthat it be provided with a lip-flange or enlargement a on the outside near the mouth, orthat it be so conformed at this point as to aflord an undercut bearing-surface, beneath which the closure may automatically grip.

A cap entsheet metal, is provided for fitting over the mouth of the bottle, and within it there is located I: sealing diaphragm or washer C,

of cork or similar somewhat elastic substance,

B, preferablystruck up from resiliwhich will form awater and airtight closure by being pressed against the mouth of the bottle. The downwardly-flanged portion of the cap (lettered b) is at the lower edge beaded,

the flange being turned inward and then outward to a point in proximity to but not touching the inner su ace of the part .b. The effect of this is to form an" inwardly-turned opened bead D, which constitutes a grippingledge ada ted to cooperate with the undercut of the ip-flange on the bottle and in position. By

matically retain the cap beading the downwardly-extending portion or flange of the cap, with the edge 0 the head in proximity to'but not touching the part b, it will be'seen that I am enabled to secure a somewhat elastic beari n g against the enlargement on the bottle, and hence it isnot absolutely necessary to slit or break the continu-.

Where it is'desirable to have a greater range of lateral elasticity, the body' of the flange as wellas the bead may be cut vertically, as illustrated in Fig. 4, or the bead alone may be slitted or cut, as illustrated in Fig. 3. The former form gives a somewhat greater range ofvertical elasticity and enables the device :5 to conform more readil to inequalities in the vertical thickness of t e lip-flange or of the sealing-disk located within the cap as well as a wider range of elasticity in a lateral direc tion.
