BOTTLE-CLOSURE.

- Application filed January 3 Specification of Letters Patent.

Patented Dec. 8, 1907.

1.1907. Serial No. 354.959.

To all whom it may concern:

Be it known that I, HENRY S. BREWING- TON, a citizen of the United States, residing at Baltimore city and State of Maryland, have invented certain new and useful Improvements in Bottle-Closures, of which the following is a specification.

My invention relates to bottle closures, the primary object being to providea simple inexpensive. closure especially adapted for bott es containing beer and other beverages.

A further object of the invention is to provide a seal or closure of metal, constructed to 4 contain a suitable packing which extends well over the outer edge of the mouth of a bottle to protect the edge and at same time to form a better sealing contact.

A still further object is to rovide the depending cylindrical portion 0 the cap witha concavo convex flange section to retain the cork and to form a closing means whereby it may be attached to the bottle by pressure upon the outward portion of the concave convex flange section, and thus cause the flange to continue to close against and under the bead of a bottle head; by this means or method of attaching my improved cap a cushion is formed by the lower edge coming in contact with the glass and the breakage of bottles is thereby greatly reduced. The more outside pressure which is brought to bear on the convex flange the more the holdin ower and greater sealing contact.

1th these several ends 1n view my invent1on consists 111 the improved construction of bottle caps hereinafter described in connection with the accompanying drawings and particularly pointed out in the appended claims.

Referring to the accompanying drawings in which like letters and figures indicate corresponding parts in the several views Fig ure 1 is a vertical section of a bottle head and stopper embodying my invention, showing the cap ready to be forced down on top of the bottle, preparatory'to attaching thereto.

Fig. 2 is a similar view showing'the cap attached, with the flange rolled beneath the head on the bottle head. Fig. 3 is a perspective view of the cap secured on the bottle head. Fig. 4 'is a sectional view showing the cap, with a compressible ring packing within the concavo portion of the depending flange. Fig. 5 is a similar view showing the cap attached to the bottle mouth with the ring compressed. Fig. 6 is a sectional view of the cap with ring packing in the concave 5 portion of the depending flange. 7 is a i similar view of the metallic cap, without the lining. Fig. 8 is a similar view with cork disk packing or lining. I the lining or disk. Fig. 10 is a view of the modified packing. Figs. 11 and 12 are edge l views of the respective packings of Figs. 9 l and 10. 111 Fig. 1, A represents a bottle head cut away to show the means employed in per- 1 forming the scaling function; 1, is a bead formed on the mouth of the bottle head A, i 2 is a groove formed beneath the bead, 3 is a l metallic cap, provided with aconcavo convex flange 4, and 5 is a flexible packing disk, made of any suitable material but preferably of cork. 111 Fig. 2 the flange is shown Fig. 9 is a view of forced. into locking contact in the groove 2 under the be:.d 1, with the packing 5 compressed between the flan e 4 and the bead 1, on the bottle head A, thereby forming the sealing contact.

In Fi s. 4, 5 and 6, I have substituted :1 modified form of packing 6 consisting of a flexible ring, made of suitable size and material, but preferably rubber for the disk, which performs the same function and in the same manner as that of the disk, viz: that it is adapted to be compressed between the flange 4 of the cap and the bead 1 on the bottle head.

It will thus be seen I have invented a clo sure or cup here a disk may be used or a ing, performing the same object of sealing and where the results are obtained by the same means.

When the bottle is to be sealed with my improved cap or closure, a pressure is brought down on top of the cap to force it in sealing relation wlth the bottle mouth; pressure is then brought against the convex portion of the concave convex depending flan e of the cap, which causes the flan e to roll inwardly towards the bottle heat until the lower edge of the fhnge is forced against the bottle neck in the groove under the bead, thus securing a holding or attaching means. This method will secure any limit to the holding power, as more pressure if brought to bear on the convex embrace the bottle neck all the more and thus form additional holding power.- By this means the variation in the sizes of botring of suitable size and material as a pack' portion of the flange will cause the flange to tle heads is provided for and having a rolled flange the risk in breaking the bottle when removing the cap is greatly reduced.

Slight changes might be resorted to in the form and arrangement of the several parts deseribed,without departing from the spirit and scope of my invention, hence I do not wish to limit myself to the exact construction as herein set forth.

' Having described my invention what I claim as new and desire to secure by Letters Patent, is: V p

1. A bottle closure made of suitable material provided with a concavo-convex depending flange adapted to be compressed on the bead of a bottle head, the diameter of the depending flange being greater than that of the bead on the bottle head, substantially as described.

- 2. A bottle closure made of suitable material provided with a concavo-convex depending flange, a suitable packing within the closure, the diameter of the flange being greater than that of the bead on the bottle head, substantially as described.

3. A bottle closure of suitable material provided with a concave-convex depending flange, a suitable acking within the closure, the flange and pac 'ing being of greater diamas eter than that of the bead on the bottle head, the flange adapted when compressed on the convex portion to roll inwardly and secure the packing between the bead on the bottle head and the said flange, substantially as described.

4. The combination with a bottle head formed with an external annular bead, of a cap comprising a disk of sheet metal and having a depending concavoconvex flange, the diameter of the flange of the cap being greater than that of the bead on the bottle head, the cap adapted to be secured to the bead on the bottle head by pressure being applied to the convex portion of the depending flange, substantially as described.

5. The combination with a bottlehead formed with anexternalannular head, of a cap comprising adisk of sheet metal and having a coneavo-convex depending flange, the diameter of the flange being greater than that of the bead on the bottle head, a suitable paeking within the cap, adapted to be secured to the bead on the bottle head by pressure applied upon the convex portion of the depending flange of the cap, substan- 5 tially as described.

In testimony whereof I aflix my signature in presence of two'witnesses.
