BOTTLE CAP AND com:

PATENT OFFICE JAMES HOWARD RICHARDS, OF CARROLLTON,

OHIO I HElflSUED Application filed September 19, 1927. Serial No. 220,394.

The present invention relates to a bottle cap and cork for use-on bottles designed for receiving the usual crimped cap, the present combined cork and cap being used either as a replacement for a bottle when opened and partially used or for original use in sealing the bottle.

The present cap and cork is so designed as to provide a cork which will fit snugly and grip the interior neck surface of a bottle as well as to provide a cap portion adapted to engage over the usual flange or bottle mouth ring and thus combines the functions of an outside engaging cap with a cork portion and the unit is so made as to furnish a tight seal for bottles having a charged content. To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing:

Fig. 1 is a vertical sectional view showing a combined cap and cork in place in a bottle neck; Fig. 2 is a View similar to Fig. 1. but showing a slightly modified structure; Figs. 3 and 4 are sectional views of the caps and corks shown in the bottle necks in Figs. 1 and 2 respectively; Figs. 5 and 6 are sectional views of modified forms of the corks shown in Figs. 3 and 4 respectively.

In Figs. 1 and 2the usual type of bottle neck is shown, this neck 1 having an outwardly bulging portion 2 with an outer portion 3 of reduced diameter and terminating at the top in aislightly overhanging flange or rim 4. The interior of the neck has an enlarged portion 5 corresponding with the bulge 2 onthe outside.

The present combined cap and cork as shown in Figs. 1 and 3, provides a cork portion 10 slightly ta ered 1n general shape but having an enlarge ring or flange 11 adjacent the bottom, the length of-the cork portion being sufiicient to allow the flange 11 to seat itself in the enlarged portion 5 of the bottle neck when the cork is forced into the bottle. In the form shown in Figs. 1 and 3 the bottom of the cork is concaved as at 12 and thus when in place in the bottle, the internal gas pressure tends to expand the sides of the corkincluding the ring 11 into the enlarged bottle neck 5, thus aiding the seal. In the form shown in Fig. 5, the end of the cork is convex rather than concave. In both cases the ring. portion 11 of the cork tapers slightly as does the upper portion 14 as this aids in forcing the cork into position. i

The upper portion of the combined unit comprisesa disc-shaped top 15 for-med integrally with the cork 10, and this disc portion has a downwardly extending outwardly flaring flange 16 which terminates in an inwardly extending ring portion 17 formed with an upwardly beveled lower edge 18. This flange 16 is sufliciently long to allow the ring 17 to engage under the upper bulge 2 of the bottle neck where it engages snugly much in the same manner as the usual crimped cap except that the present cork is made of a resil ient material such as rubber and is sprung or forced into engagement. In the form shown in Figs. 2 and 4, the cap and cork are similar to the first form inall respects save for the cork portion 20 which in this form tapers from top to bottom and is provided at a point so as to engage in the enlarged portion 5 of the bottle neck, with an encirclin bead or ring 21. The bottom 22 of the cor may be either convex as shown in Figs. 2 and 4, or maybe hollowed out as at 23, shown in Fig. 6.

The inwardly beveled edge 18 on the cap portion of the cork allows the cap to cam itself into engaging positionover'the bottle neck and-at the same time aids in easy removal as it forms a finger grip so that one side ma be moved up and over the top bulge of the ottle when the further removal is easily accomplished. a

It has been found that with the extra flange or ring on the cork portion adapted to seat tightly in the interior enlargement of the bottle neck that the present eombined cap and cork will hold under relative high gas presrubber producing t e most, satisfactory results. These units may be used repeatedly, and until their resiliency is lost, will efi'ectively seal the usual type of bottles-holding .charged beverages such as ginger ale, near beer, and the like, without the loss of eitherliquid or gas.

Other modes of applying the principle of our invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.-

We therefore particularly point out and distinctly claim as our invention:

1. A combined rubber bottle cap and cork consistin of a cork portion in the form of an elongate slightly tapering plug, said plug having an enlarged ring adjacent the lower end, said plug having a concave bottom surface of a depth not exceedin that of said enlarged ring and an integral y formed cap member having an outwardly and downwardly depending flange terminating in an inwardly extending thickened ring portion,

said flange and ring portion beingadapted to be forced over and around the bottle neck to bring said ring portion into elastic engagement therewith below the upper head.

2. A combined {rubber bottle cap and cork consistin of a cork portion in the form of an elongated sightly tapering plug, said plug having an enlarged ring adJacent the lower end, said ring bein also slightly tapered and being so positione as to normally engage in the enlarged portion of a bottle neck, said plug having a concave bottom surface of a depth not exceeding that of said enlar ed ring, and an integrally formed cap mem er having an outwardl and downwardly de-' pending flange terminating in an inwardly extending ring portion, said flange and ring portion being adapted to be forced over and around the bottle neck to bring said ring portion into elastic engagement therewith below the upper head.

3. A combined rubber bottle cap and cork consistin of a cork portion in the form of an elongate sli htly tapering plug, said plug having an en arged ring ad'acent the lower end, said ring being also slightly tapered and being so positioned as to normally engage in the enlarged portion of a bottle neck, said slug having a concave bottom surface of a epth not exceeding thatof said enlar ed ring, and an integrally formed cap mem er having an outwardly and downwardly de- Signed by us this 15thday of August, 1927. 7
