Oct. 22, 1935. A. BERENDT MEASURING STOPPER FOR BOTTLES Filed Oct. 7, 1955 INVENTOR. 19 Befienaf- BY 3 A TTORNEY Patented Oct. 22, 1935 UNITED STAT 1 Claim.

One object of this invention is the provision of a stopper for bottles or flasks by means of which a given quantity of the liquid contents of the bottle may be poured out by a single tilting of the bottle, the flow automatically stopping when the given amount has passed out.

Another object of the invention is the provision of a bottle stopper such as above-mentioned with means for automatically closing the bottle outlet when the bottle is returned to its upright position after a quantity has been poured therefrom.

A further object of the invention is the provision of a detachable means which may be applied to a stopper of the ordinary type of cork or rubber stopper, to convert said stopper into a measuring stopper of the kind above-mentioned.

The above and other objects will be come apparent in the description below, in which characters of reference refer to like-named parts in the drawing.

Referring briefly to the drawing, Figure l is an elevational view of a bottle equipped with the measuring stopper.

Figure 2 is a fragmentary cross-sectional elevation-al view of the same.

Figure 3 is a view similar to Figure 2 showing the bottle in tilted position.

Figure 4 is a cross-sectional view through the stopper.

Figure 5 is a, plan view of the stopper.

Referring in detail to the drawing, the numeral I represents a bottle having the neck H. Within the neck I l is mounted a removable stopper l2 of any desirable material, the same being provided with a flanged top I3 adapted to overlap the neck of the bottle.

The stopper is provided with an axial bore M in which a cylindrical tube I is mounted. Both ends of the bore It are bevelled to accommodate the outwardly-curved peripheries of the tube l5.

The ends of the tube l5 are slitted to form spaced-apart tongues 2|, the latter after the tube has been mounted in the bore M, being bent outwardly to provide a tapering seat for the valve-like members about to be described.

A length of cord or other flexible string passes through the tube l5, and at each end is secured a pear-shaped member l6 and H, which may be formed of rubber and may be provided with a weight-like core 18. The cord I9 is attached to these members in such manner that the narrower ends of the members face each other, and it is of a length slightly less than that of the tube l5. In order to prevent opening of the bottle during transit or before it is brought into the household for use, a seal of any desirable material such as Cellophane, is provided, as shown at 20.

When the filled bottle stands upright, the upper member I6 is weighted down by the mem- .5 her I! to close the mouth of the tube l5. When the bottle is tilted to the position shown in Figure 3, the liquid will flow into the tube and fill the latter, the member It} still closing the tube. When the bottle is tilted furthenthe weighted 10 member It will fall from its position in; the mouth of the tube and thereby permit the outflow of the liquid contained within the tube. At the same time, however, the weight of the member l6 causes the member I! to be pulled against the lower entrance of the tube, thus preventing any more liquid from flowing from the bottle into the tube. Hence no more than the amount of liquid equal to the colume of the tube, or slightly in excess thereof, will flow from the bottle upon single tilting of the bottle.

When it is desired to convert an ordinary cork or rubber stopper into such a measuring stopper,

a hole is first bored through the stopper. The tube IS, with its ends merely slitted as abovementioned without bending the tongues 2i back,

is then inserted into the bore, with the cord I9 having the members It and l? attached thereto, and finally the tongues 2! are bent back as above-described, thus providing the seats for said members and at the same time locking the tube l5 in the stopper.

For different quantities to be poured at a single tilting of the bottle, the length of the tube may be varied according to the quantity desired.

Obviously other modifications in form and structure may be made without departing from the spirit and scope of the invention.

I claim:

A bottle stopper having an axial bore therein, a tube mounted in said bore and having its ends outwardly flared to form tapering seats, a flexible string passing through said tube, and a pearshaped valve member secured to each end of said string, the upper of said members seating in the upper of said seats when the bottle containing the stopper is upright and the lower of said members being suspended at a distance from the lower of said seats, tilting of the bottle from the upright to the horizontal position causing the lower of said members to fall against the lower rim of said stopper and said string being thereby bent around said lower seat, said lower member thereupon lying in a, position downwardly inclined from the axis of the main body of said 5 string to permit a wide opening of the lower end of said bore.

ALFRED BERENDT.
