2 Claims.

This invention relates to container closures and more particularly to bottle stoppers of the type using plugs made of ordinary cork.

To remove such corks, particularly if they are fast in the bottle neck, recourse is usually had to a helical instrument known as a cork screw, or to a lever-like device, any and all of which pierce, cut and mutilate the cork material, rendering it unfit for further use and frequently causing fragments to separate and enter the bottle.

removed by hand, entirely without the use of any extraneous appliance.

A further feature is in the provision of means for uniting the cap and cork in a novel and positively secure manner whereby no amount of wringing will cause separation.

A further purpose is to produce a stopper of ornamental and symmetrical appearance, capable of repeated removal and insertion without detriment or damage to the stopper.

These advantageous objects are accomplished by the novel construction and combination of parts, hereinafter described and illustrated in the accompanying drawing, constituting an essential component of this disclosure, and in which:

Figure 1 is a perspective view showing an embodiment of the invention, parts being broken away to disclose the construction.

Figure 2 is a similar view of the integrally combined metal band and cap disc forming a unitary cup.

Figure 3 is a like View of the ring.

Figure 4 is a perspective view of one type of cork employed.

Figure 5 is a sectional view showing a slight modification in construction.

Referring in greater detail to the drawing, an ordinary cork, designated by the numeral 15, is shaped in the form of a tapered, or if preferred, a straight plain cylindrical plug of such dimensions as are compatible with its purpose, which is commonly to enter a distance into a bottle neck, its outer, larger diametered portion l6 extending beyond the edge of the bottle mouth.

Fitted to tightly engage around the extending end of the plug is a ring ll, of rigid material, such as; metal, wood, compressed fibre, hard rubber or molded phenolic condensate, known under the term bakelite or similar substance, the diameter of the ring bore being smaller than the largest diameter of the cork.

The ring I! has a conical axial opening i8 which may conform to the taper of the plug, and blending into the upper end of the opening is a narrow, acutely bevelled, annular recess l8 preferably roughened or corrugated and adapted to be filled with any suitable adhesive by which the ring is firmly fixed on the exposed peripheral surface of the plug.

In the under side of the ring is an annular groove 20, to seat upon the rounded edge of the bottle mouth when the plug is fully inserted.

A cup of metal, or other preferred rigid material, includes a disc 22, of a diameter to agree with the diameter of the ring, the same being provided with a central raised portion 23 forming a shallow cavity in its under side suited to receive the extreme end of the plug; this raised portion, its surrounding margin, or both, may be enamelled in colors or utilized as an advertising space.

A metallic band 25 extends integrally in the manner of a skirt, from the edge of the disc 22, the band being forced tightly over the periphery of the ring I! and may be further secured to it by spinning, crimping or otherwise slightly inflanging its extreme lower edge 26 even into the groove 20.

In the modification shown in Figure 5, the rigid ring I! is provided with a narrow outstanding flange 21, at its lower edge, against which the band edge 26, makes contact when the parts are assembled.

From the foregoing, it will be understood that the plug, whether of cork, rubber or composition, is rigidly secured in the ring [1, held by the concave portion 23 of the cup and that these several elements are constrained as a unit by the cup band 25, which affords an effective gripping surface for the fingers in removing or replacing the stopper.

Although the foregoing is descriptive of the best known embodiment of the invention, it will be understood that minor changes and modifications may be resorted to without the exercise of invention and within the spirit and scope of the appended claims.

Having thus described the invention and set forth the manner of its construction and use, what is claimed as new and sought to secure by Letters Patent, is:

1. A bottle stopper comprising a plug, a rigid ring tight fitting the end of said plug, said ring having an outstanding annular flange on the bottom of said ring, and an inverted metallic cup pressed over said ring to seat upon said flange.

2. A bottle stopper comprising a conical plug of cork adapted to be entered into a bottle mouth, a molded ring of hard synthetic composition having a tapered axial opening through which said cork is inserted, said ring having an annular flange on its lower portion and a sharply defined interior bevelled surface blending into the axial opening at its upper end, said recess being receptive of a strong adhesive filling, an inverted cup consisting of a circular metallic disc having a central raised surface to receive the cork end and a metallic band depending integrally from the edge of said disc to tightly enclose the periphery of said ring, said band having its edge seated on said flange.
