Application filed July 24, 1912, Serial No. 711,293.
To all whom it may concern:
Be it known that I, GEORGE W. MITCHELL, a citizen of the Dominion of Canada, resident of New York, in the county of New York and State of New York, have made a certain new and useful Invention in Bottle- Caps; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which itappertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
Figure l is a central verticalsection of the invention in its normal shape, applied to the bottle. Fig. 2 is a similar view with the cap compressed to seal the bottle. Fig. 3 is a plan view of the cap. Fig. 4 is aside view of the same. Fig. 5 is a central ertical section of thecap, the disk being removed.
The invention relates to improvements in means for closing bottles in an airtightimanner, and it consists in the novel constructionv and combinations of forth.
The ordinary pliable or sheet metal bottle caps of tin failto completely close the bottles, because in their structure suflicient allowance-isnot made for slight nicks or irregularities of shape of the marginal portion of the bottle neck, these being usually .on the parts, as hereinafter set upper or outer portions of the margin, which are more exposed to casual injury than the inner surface of the marginal entrance. By the present device it is designed, to a great extent, to obviate this difliculty.
In the annexed drawing, illustrating the invention, the numeral 2 indicates the upper portion of the neck of an ordinary bottle, having the usual exterior marginal bead terminating in a circumferential shoulder 3, the margin of the mouth of the bottle being rounded inward and downward from its top surface, as indicated at 4.
A circular closure cap 5, made of thin metal, is designed to be ressed in normal shape, in which it is provided with a down ward and outward turned flange 6, which may be marginally crimped inthe usual manner. The upper part of the flange is smooth, joining the top 7 of the cap in a rounded bend 8, and the top is provided with a hollow boss or circular rise 9 in its central portion, the top of this raised central Specification of Letters Patent.

Renewed September 20, 1913. Serial No. 790,854.
part being connected to an annular slightly convex portion 10, around it, by its straight inclined wall 12 so that it has the form of a conical frustum. The top of the-frustumshaped rise may be plane or slightly convex, and the conical inclined wall 12 slopes straight downward and outward therefrom to the annularportion of the cap, being connected to said top and said annular portion respectively by convexed and concave rounded bends. On its interior or under surface the rise 9 appears reversed, or as an indentation or circular recess seat havinga straight sloping or beveled circular side wall joining the annular portion 10 of the cap. In this cap is fitted a thick circular disk 14,0f soft elastic material, such as rubber, which is designed to hold its place in the seat by its elasticity,- its edge being automatically pressed against the inside of the downward turned flange. The diameter of the central rise of the cap is slightly less than that of the inner circumferential surface of the mouth of the bottle and its sloping wall' is designed to have the strength of a cone-like structure wherein the inclined elements are straight. y
The cap innormal shape is to be applied to the top of the bottle neck in the usual manner, the crimped flange being pressed inward under the bead of the neck and against its shoulder. At the same time it is designed that the, annular portion 10 of the cap 'shall be brought against the surface of the being elastic, will form a tight joint between said downward slope and the surface of the bottle mouth, and provide an effective closure. In this operation the normal upstand-.
ing form of the central rise is preserved, because of. the strength of its conical highangle wall. At the same time the thickness of the rubber disk gives it. sufficient body to act, in connection with the downward slope or bend of the annular portion of the cap,
- may use the closure and cap upon all receptacles similar to bottles.
Having described the invention, what I Y claim and desireto secure by Letters Pat ent is:
A closure for bottles and like receptacles, comprising a sheet metal bottle cap adapted for use with a packing, comprising a raised boss centrally of the cap, and having a rigid wall extending downwardly from the raised top of said boss, the inner end of the said boss having a diameter less than that of the orifice of the bottle to which the cap is tobe applied, an annulus extending circumferentially away from the lower end of the said rigid wall of the said boss, and bendable by the downward and inward movement of the boss to an upward slope away from the sai'dlower end of the said rigid wall of the said boss, the said rigid wall of the said boss during and after the downward movement thereof extending downwardly from the top of said boss to said annulus, and gripping means at the periphery of the said annulus. 2. A closure for bottles and like receptacles, comprising an elastic member, means for holding the peripheral portion of said member against the external walls of the orifice of the bottle, .and means for maintaining the central portion of the said member tensed and extended, and depressed with respect to the peripheral portion thereof, said central portion being within the orifice of thebottle. p 3. A closure for bottles and like receptacles, comprising a stretchable disk, means for holding the peripheral portion of said disk against the external walls of the orifice of the bottle, and means for maintaining the central portion of the disk tensed and extended, and depressed with respect to. the peripheral portion thereof, said central por tion being within the orifice of the bottle, the part of said central depressed portion of the said disk adjacent the internal walls of the orifice of the said bottle being forced against said internal walls.
4. A closure for bottles andlike recep' tacles, comprising an elastic member, a cap, the peripheral portion ofsaid cap being adapted to hold the peripheral portion of said elastic member against the external walls of the orifice of the bottle, the central portion of said cap being driven belowvthe peripheral portion thereof, the said elastic member being extended and maintained in atensed condition within the orifice of the bottle. 7
. 5. A closure for bottles and like receptacles, comprising an elastic disk, a cap, the
peripheral portion of said cap holding the peripheral portion of thekelastic disk against the external walls of the orifice of the bottle, the central portion of said cap being driven below said peripheral portion thereof, the said elastic disk being extended and maintained in a tensed condition within the orifice of the bottle.
6. In combination, a sheet metal bottle cap and a bottle, said cap comprising an annular portion, and a hollow boss projecting upwardly from said annular portion and having an upstanding periphery joined to said annular portion, soft material held by the said annular portion intermediate said cap and the said bottle, means for securing said annular portion to said bottle, a portion of said annular portion being spaced from and out of contact with the interior periphery of said bottle, so that it can be bent againstsaid 7. A closure for bottles and like receptacles, comprising an elastic disk, means for holding the peripheral portion of said disk against the external walls'of the orifice of the bottle, and means for maintaining the centralportion of said disk tensed and extended, and depressed with respect, to the peripheral portion thereof, said central portion being within the orifice of the bottle.
In testimony whereof I aflix -my signature, in presence of two witnesses.
