STOPPER Ohio, assignor to a corporation of Application July 14, 1930. Serial No. 467,725

2 Claims.

The present invention has for its object to produce a simple and novel stopper that may be easily applied to and removed from a bottle, produce a tight seal when on the bottle, and be I adapted to be used over and over again on the same or different bottles.

The various features of novelty whereby my invention is characterized will hereinafter be pointed out with particularity in the claims: but, for a full understanding of my invention and of its objects and advantages, reference may be had to the following detailed description taken in connection with the accompanying drawing, wherein:

t Figure 1 is an elevation of the stopper in the condition in which it reaches the consumer; Fig. 2 is a central axial section through the stopper, in the same condition as it appears in Fig. l, and the neck of a bottle in which the plug por- M tion of the stopper has been inserted; Fig. 3 is a side view of the neck of the bottle having therein the improved stopper adjusted into its final position of use; Fig. 4' is a section on line 4-4 of Fig. 3 and Fig. 5 is a top plan view 01'. the stopper as it appears in Figs. 1 and 2.

The stopper, which is made of soft rubber, comprises a plug portion 1 and a cup-shaped or bell portion 2 above and integral with the plug. The annular wall of the cup or bell is made comparatively thin at the bottom, as indicated at 3, and is gradually thickened to produce a wide outwardly projecting rib or bead 4 around the top. The diameter of the bell or cup is somewhat greater than the diameter of the plug so as to produce an annular shoulder 5 at the top of the plug which will prevent the stopper from being pushed too far into the neck of a bottle. The exterior of the plug may be grooved circumferentially at short distances apart throughout its length, in such a manner as to produce a se ries of sawtooth ridges 6. Furthermore, there may be a deep central depression or recess 7 extending up at the center of the plug from the bottom face. A plug made in this way can be easily inserted in the neck of a bottle and at the same time make a tighter joint than will a solid smooth plug.

In using the stopper, the plug is first inserted in the neck of the bottle as indicated in Fig. 2, and then the cup or bell is turned inside out so that the annular wall extends downwardly instead of upwardly. The thin section of this annular wall permits this reversal to be easily accomplished. However, the free rim portion of the cup or bell is stiifer and will therefore grip the periphery of the bottle neck firmly underneath the external bead a usually found on the neck A of a bottle. as shownin Fig. 4. Furthermore, the comparatively thin web section 3 will stretch, it the parts are properly proportioned, so as to be drawn tightly over the rib a.

It will therefore be seen that when the parts of the stopper have assumed their final positions upon the bottle there will be a-triple seal, the first being between the plug and the surrounding bottle neck, the second being between the thin web portion of the cup or bell that is drawn taut over the head on the bottle, and the third being between the expanded ring-like bead 4 that hugs the bottle neck tightly along the under side of the bead on the bottle and the surfaces on the bottle immediately below the bead.

While I have illustrated and described with particularity only a single preferred form of my invention, I do not desire to be limited to the exact structural details thus illustrated and described; but intend to cover all forms and arrangements which come within the definitions of my invention constituting the appended claims.

I claim:

1. A bottle stopper consisting of a single piece of rubber having the form of a plug and a bellshaped cup larger in diameter at the bottom than the top of the plug rising from the top of the plug in an upright position, the annular wall of the cup being in the form of a thin web adjacent to the bottom of the cup and increasing gradually in thickness in the outward direction toward the top to form at the top a heavy bead whose under slope forms the outer face of said annular wall, said plug having peripheral grooves extending around the same and a deep cavity extending upwardly therein through the bottom face past the planes of the several grooves.

2. A bottle stopper consisting of a soft'rubber plug adapted to enter the neck of a bottle and a cap attached to the plug and adapted to embrace the said neck, said plug having thereon several external annular ridges distributed lengthwise of the same, each of the ridges with that portion of the plug surounded thereby being in the form of a frustum of a cone whose large end is at the bottom, whereby each ridge has an annular under face extending approximately at right angles to the long axis of the plug and an upwardly and inwardly facing conical surface, and there being a deep cavity extending up along the center of the plug from the bottom past the planes of several of said ridges.
