BOTTLE STOPPER Filed Feb. 26, 19 55 IN VENTOR.

his ATTORNEY.

Patented Mar. 9, 1937 UNITED STATES FATENT OFFICE 2,073,043 BOTTLE STOPPER Wilhelm Albrecht, New York, N. Y. Application February 26, 1935, Serial No. 8,244 2 Claims. (01. .215- "vs) My invention relates to an improvement in bottle stoppers. The primary object of the invention is to provide a removable stopper to fit within the neck of a bottle, which includes, in association therewith, a counterbalanced closure, or cap for the bottle, which automatically covers the stopper when the bottle is in an upright vertical position. The closure, or cap, functions automatically to uncover the bottle stopper when the bottle is tilted into a position to pour out the contents of the same.

A further object of the invention is to provide an extending tubular member positioned with the stopper facilitating the withdrawal of the liquid contents of the bottle in such a manner aS to prevent the same from passing over the top surface of the stopper.

Another object of the invention is to construct a stopper to permit the removal of the automatically operating cover attachment therefrom.

My invention further includes other objects and advantages hereinafter more particularly referred to in connection with the detailed description of the same with the accompanying drawing, which 25 show the invention in its preferred physical embodiment.

Referring to the drawing:

Fig. 1 is a perspective view of the bottle stopper constructed in accordance with the present in- 30 ventive conception illustrating the same mounted on a bottle, which is in a tilting or pouring position.

Fig. 2 is a side elevation of the bottle stopper attachment indicating the cover of the same in 35 a closed position.

Fig. 3 is a detailed perspective view of the connecting member employed for pivotally retaining the counterbalanced cover member of the stopper thereon.

Fig. 4 is a similar view of the bottle stopper with the cover attachment removed therefrom.

Fig. 5 is a detailed perspective view. of the member employed for positioning the stopper within the neck of the bottle.

Fig. 6 is a detailed plan view of the cover attachment, and

Fig. '7 is a detailed perspective view of the extending tubular member permitting the passage of the contents of the bottle through the stopper. 50 The bottle stopper, as herein disclosed, comprises a tapering retainer member ID, indicated in detail in Fig. 5, formed of cork, or a similar compressible material, which is removably located within the neck of a bottle I l. The taper- 55 ing retainer 19 includes a central longitudinal opening [2, through which a tube l3 extends, the tube being held firmly in position therein by the circumferential interior surface defining the opening in the retainer. An interiorly threaded outer portion or band 14 is positioned about the upper peripheral surface of the cork retainer. The band includes external upper and lower flanges 45 and I6 respectively. A plurality of projecting lugs H are located in the surface of the band situated between the limiting flanges l5 and IS. The associated relationship of the cork retainer member It}, band I4 and tube I3 is clearly illustrated in Fig. 4 of the drawing, which shows an assembly view of these elements of the invention. The portion of the retaining member 19 below the band I4 is employed to securely hold the connected parts within the neck of a bottle as indicated at l8 in Fig. 2. The tubular member provides a passageway for the contents of the bottle to flow through the stopper, this tube extending above the upper or top surface of the stopper as defined by the flange 15 and cork H) in order to prevent a flow of liquid over this portion of the device, when the bottle is tilted for this purpose. The portion of the stopper projecting above the top of the neck of the bottle provides a retaining means for positioning an automatically operative cover attachment thereto, as will hereinafter be more particularly described.

With particular reference to Figs. 3 and 6 of the drawing, the removable stopper cover attachment herein disclosed comprises a circular band l8 having raised parallel arms l9 extending therefrom. This spacing member of the attachment is also provided with indentations 20, and when placed in position between the spaced circumferential flanges l5 and I6 and around the band M of the stopper, the same mesh with the projections H and prevent the adjoining parts from moving with relation to one another in assembled relationship. By spreading the arms IQ of the circular band 18', the same may be removed from a position about the periphery of the stopper band 14. Adjacent openings in the end portions of the respective extending arms of the spacing member, as indicated at 2|, are adapted to pivotally maintain side lugs 22 on the body of a cover member 23, Fig. 6. One end of the cover member 23 is of a closed top cylindrical shape, as indicated at 24, having an interior washer 25 of cork, or similar material, which closes the extending tube l3 when the bottle containing the stopper is in a vertical position, as shown in Fig. 2. A counterweight 26 is located at the opposite end of the cover member 23, counterbalancing the weight of the cylindrically shaped closing portion of the cover, so that, when the bottle is tilted to pour the contents therefrom, the closing portion 24 will automatically uncover the mouth of the tube l3, as indicated in Fig. 1. Lugs 21 are provided on the cover member to limit the degree of movement between the pivotally connected parts of the bottle stopper attachment.

While I have shown and described the preferred embodiment of my invention, I do not desire to limit myself to the specific form illustrated, but may alter the construction and arrangement of parts, as occasion requires, without enlarging the scope of my invention, or departing from the spirit thereof, as contained in the appended claims.

I claim:

1. A bottle stopper, having an upper portion projecting above the neck of the bottle in which it is adapted to be secured, said portion including a band having upper and lower flanges, a spacing connection fastened about said band between the fianges thereof, and a counterweight cover attachment pivotally mounted in said spacing connection for closing the top of the stopper when the bottle is in a vertical position.

2. A bottle stopper having an outer portion comprising an integral band having upper and lower external flanges, a spacing connection secured between the flanges of said outer portion, a counterweight cover attachment pivotally mounted on the spacing connection for closing the top of the bottle stopper, and means for securing the stopper upon the neck of the bottle.
