WILLIAM H. NIEMEYER, OF BALTIMORE, MARYLAND.-

BOTTLE GAP OR CLOSURE;

To all whom it may concern:

Be it known that I, WILLIAM H. NIE- -MEYER, a citizen of the United States, residire; at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Bottle Caps or Closures, of

which the following is a specification.

This invention relatesto im rovements in bottle caps or closures, and t e object is to provide a metal cap of the type having'a peripheral flange to be tucked or pressed in under the head of the bottle or jar, so constructed that the flange thereof will readily accommodate itself to the slight variance in size in the bottle beads .without breaking or splitting in such a manner as to destroy its effectiveness as a seal.

Vith the above object in view, the invention consists in the n'ovelfeatures of construction hereinafter fully described, particularly pointed out in the claims, and

clearly illustrated drawing, in which Figure 1 is a sectional view of a cap constructed in accordance with my invention, taken in the'line a:w of Fig. 2 Fig. 2, an elevation of the cap; Fig. 3, a sectional view onthe line y{i of Fig. 1, nd Fig. 4, asectional View of the cap in position closing the mouth of the bottle.

Heretofore metal ca s have been provided by the accompanying for sealing bottles, sai caps having continuous flanges, the lower portions of which are tucked or ressed in under the bead of the bottle. T e beads of bottles vary slightly in size, that is, in circumference, with the re-' sult that if either smaller or larger than the internal diameter of the flan e of the cap,-

the latter will break or s lit w en pressed in under the former, in sue manner as to pre- -vent a perfect seaL. I obviate th s objeetlon by providing the flange at intervals about its circumference with thin web-portions of such slight thickness that the metal at this oint will break should the bead be either arger or smaller. The vertical extent of this break, however, is limited so that it cannot extend upward a sufficient distance to destroy the effectiveness of the seal. Should the bead be smaller, these thin web-portions} Specification of Letters Patent;

by breaking pre ent puckering of the flange by reason of the superfluous metal and, permitthe separated portions of the flange to be tightly tucked 1n under the bead of the bottle. Y v

Referring now more particularly to the drawing, 1 designates the caphaving the depending flange 2. f This flange is provided at intervals about its circumference with perforations 3, which are placed a suflicient distance below thetop of the cap to prevent anydanger of interfering with a perfect seal. E xtending from the lower ed e of the flange, on the inner and outer side t ereof, and terminating at the perforations 3, are substantially V-shaped grooves of such depth as to 7 leave a thin wall orweb portion 4. Thus the flange is formed of a pluralityof depending portions connected Hy thin web-portions 4..

As shpwn in Fig." 4, the metal cap is so cured upon the bottle by pressin in the flange under the head, at several points about its circumference, the usual cork disk 5 being placed on the-inside of the cap.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent of the United States, is

1. A bottle sealing cap having a top and a continuous flange integral therewith formed about its circumference with a plurality of spaced perforations and thin web-portions extending from the edge thereof to said perforations; A

2. A bottle sealing 'cap having a top and a continuous flange integral therewith formed at intervals about its circumference with thin Web-portions extending upward from the edge'the'reof and perforations in which said thin portions terminate, said perforations being disposed a suflioient distance below the top of the cap to be below the upper. edge of the bottle top whenthe cap is in posi tion thereon. l
