Application tiled November 25, 192i.
To all whom it may concern: A
Be it known that l, JOHN Verts, a citizen ot the United States, resident of Lakewood,-
county of Cuyahoga, and State of UhiO, have e invented new and useful improvements in Bottle Stoppers, otV which the following is a specification; the principle ot the invention being herein explained, and the best mode in which l have contemplated applying that principle, so as to distinguish it from other inventions.
ll/ly invention relates to Stoppers or caps for bottles and particularly to devices of this naturet'or milk bottles. Thedesign of the invention is to provide a milk bottle stopper which can be manufactured very economically in quantities; which can be repeatedly utilized for an indefinite period; which may be readily and thoroughly cleansed so as to satisfy the necessary sanitary requirements for an'article of this nature; which can be easily placed and removed; and which shall 'serve as an eil'ective stopper. v
The annexed drawing and the following description set forth in detail certain means embodying my invention, such disclosed means, however, constituting but one of the various embodiments in which the principles of my invention may be used.
lin said annexed drawing:
Figures l and 2 represent, respectively, a plan view and a side elevation ot' my improvedv bottle stopper;
Figures 3 and 1i represent vertical sections taken in the planes indicated by the respective lines TTT-TTT and Tlf-TV, Figure 1;
Figure 5 represents a fragmentary vertical section of a milk bottle with my improved stopper locked in position therein: and
Figure 6 represents a fragmentary section in the plane indicated by the line Vl-Vl, Fi ure 5.
eterring to the annexed drawing in which the same parts are indicated by the same respective ordinals in the several views, a milk bottle is suggested by the ordinal l to which my improved stopper is intended to be applied, the body of which is indicated by the ordinal 2. This body 2 is in the form of a disc of vulcanized or suitably cured rubber or similar material, this disc being of any suitable thickness, preferably of about Serial No. 517,423.
one-eighth inch. This body 2 is formed with an suitable linger grip and l have herein ilustrated as preferable an integral upwardly extending ear 3 having a concave tace surface i to insure areliable grip, two of such faces i being herein shown, one upon each side of the plate-like ear 3. The body 2 is not a plane disc but is concavo-convex, the concave portion, in the form of stopper illustrated, being the under-surface ofthe body 2, as plainly shown in the accompanying drawing. Also, preferably, for a reason hereinafter given the plane containing the peripheral edge 6 of the body 2 is not at right angles to the plane containing the diameter ot the body 2 but is inclined outwardly :trom the bottom to the top of said peripheral edge t. The diameter ot the body 2 in the plane containing the upper edge ot the surface 6 is substantially the same as the diameter ot the surface 8 out the neck of the bottle l with which the cap is designed to co-operate. The cap 2 is placed in the neck of the bottle l sd as to rest upon the shoulder 9 usual to such bottles and then suiiicient stress eX- erted upon the body 2 through the medium of the plate-like ear 3 to reverse the concavity oi' the stopper, i. e., in the form illustrated, to press the central portion of the body 2 through the central horizontal plane of said body so that the concave portion ot the body then lies in its upper surface, as plainly indicated by ordinal 7, Figures 5 and 6. This action increases the diameter of the body 2. The tendency of the stopper to return to its normal concavity results in a gripping action vbetween the periphery of the stopper and the neck of the bottle, and, of course, results in a decrease in the depth of the concave surface 7, as compared with the concave surface 5, as plainly shown in Figures 6 and 3. By reason of the provision of the beveled edge 6, it is possible to press the central portion of the cap 2 through its central horizontal plane, from the position shown in Figure 3, to the position shown in Figure 6, with the least diliculty, the open space 10 allowing for a part of the increased rubber material which is pressed into the area 8 when the diameter of the cap tends to be enlarged. The tendency of the cap 2, when in the position shown in Figures 5 and 6, to regain its normal form, tends to create a vacuum beneath the cap which in turn creates a suction thus holding the cap even more tightly to the neck of the bott-le.
That` l claim is l. A bottle stopper of vulcanized rubber or its equivalent, consisting ot a concavoconvex disc, said stopper being adapted to be locked within the mouth or' a bottle by reversing its concavity, the tendency of the stopper to return to its normal concavity producing a gripping action between the pee riphery of the stopper and the neclr of the bottle.
2. A bottle stopper of vulcanized rubber or its equivalent, consisting of an upwardly bulged disc, said stopper being adapted to be locked within the inout-h of a bottle by pressure, thereby reversing its concavity, the
tendency or the stopper to return to its normal concavity producing a gripping action between the periphery of the stopper and the neclrl of the bottle.
,3. A bottle stopper of vulcanized rubber or its equivalent, consisting of a concave-convex disc, having a beveled peripheral edge, said stopper being adapted to be locked within the mouth of a bottle by reversing its concavity, the tendency of the stopper to return to its normal concavity producing a gripping action between the periphery of the stopper and the neck of the bottle.
el. A bottle stopper of vulcanized rubber or its equivalent, consisting of an upwardly bulged disc, having its peripheral edge bev eled outwardly from bottom4 to top, said stopper being adapted to be locked within the mouth of a bottle by pressure, thereby reversing its concavity, the tendency of the stopper to return to its normal concavity producing a gripping action between the periphery of the stopper and the neck of the' bottle.
5. A bottle stopper or" vulcanized rubber or its equivalent, consisting of an upwardly bulged disc formed with an integral linger e grip, said stopper being adapted to be locked within the mouth of a bottle by pressure, thereby reversing its concaif'ity, the tendency ot' the stopper to return to its normal concavity producing a gripping action between the periphery ot' the stopper and theme01( ot the bottle.
