Application January 6, 1934, Serial No. 705,588 1 Claim. ((11. 215-48) My invention relates to bottle stoppers and more particularlyto conventional cork stoppers.

The general object of the invention is to provide the cork stopper with a simple and inexpensive cap whereby the stopper can be readily withdrawn from a bottle or the like Without the use of a cork-screw. V

' Heretofore it has been proposed to anchor a cap to a cork bottle stopper by forming the cap with a peg or projection fitting into a bored hole formed in the cork body and in some instances by means of a separate wedge or other member extending through the cap and into the cork body. Both these methods proved objectionable, because of the difficulty encountered in boring the cork and the fact that the caps made with a peg attached have a tendency to strip away from the cork in the first instance, whereas in the second the wedge frequently works loose and becomes lost.

The foregoing objections have been overcome in the present invention by providng the cap member with an integral arcuate fin adapted to cooperate with a correspondingly shaped narrow slot cut in the top of the cork body.

Other objects and advantages of the invention will be apparent as the specification is considered in connection with the accompanying drawing, in which:

Figure 1 is a longitudinal section through a cork bottle stopper and cap therefor constructed according to my invention;

Figure 2 is an enlarged longitudinal section on the line 2-2 of Figure 1;

Figure 3 is a top plan of the cork with cap removed therefrom; and

Figure 4 is a bottom plan of the cap disconnected from the cork stopper.

Referring more particularly to the drawing 1 denotes a bottle stopper comprising a cork body 2, preferably of the usual tapered configuration or contour, and a composition cap 3 therefor. The cap 3 is made preferably of bakelite or other suitable material capable of being readily molded into the desired shape, and of suificient hardness and tensile strength for its intended purpose. The bottom face of cap 3 is formed with a central shallow recess or depression 4 in which the top of the cork body portion 2 is snugly received.

The cap 3 is formed with a depending preferably arcuate fin portion 5, extending transversely through the axis of recess or depression 4 and is molded into the bottom of the cap. This fin is adapted to be inserted in an arcuate recess or slot 6 formed in the top of the cork body by means of a circular saw, not shown, thus greatly reducing the cost incident to boring and other operations necessary in making bottle stoppers of this general type, now on the market. It is of course essential that the fin 6 extend at right angles to the axis of the cork body I so that there can be no relative turning movement of the cap and body portions of the stopper. Any suitable adhesive material 1 may be employed to securely cement the cap 3 and its fin 5 to the top of the cork body and the arcuate recess respectively. The ends of arcuate slot 6 terminate a considerable distance from the periphery of the cork body so that the latter will not be weakened.

Having thus described my invention:

What I claim as my invention is:

A bottle stopper comprising a cylindrical cork body having an arcuate recess in its upper face intersecting the axis thereof and having its ends terminating some distance from the periphery of the cork, a cap of moldable material having a recessed bottom and a centrally located fin formed integral with the recessed bottom of the cap and of an arcuate shape and size to correspond and snugly fit the recess in the upper face of the cork, and the cap and fin cemented to the cork.
