REPLACEABLE CLOSURE Filed Deo. 4, 1930 www A TTORNEY.

Patented May 1, 1934 UNITED STATES PATENT OFFICE REPLACEABLE oLosURE Walter E. Richter, Milwaukee, -Wis. Application December 4, 1930, serial No. 499,986 7 claims. (ci. cls- 78) This invention relates to temporary closures or caps for bottles and like containers, and particularly applies to that class having valve and nozzle features arranged for producing a flzz stream under the pressure of an etervescent` beverage.

One of the primary objects of the invention is to provide a replaceable cap for'bottleawhich is inexpensive to construct and which will effective- 1y seal the contents ofthe bottle despite small variations in the size and shape of the bottle neck to which it is attached. Y

Another primary object of the invention is to produce a replaceable bottle cap having a nozzle provided with a self closing valve which maybe conveniently operated and which is simple and inexpensive to construct.

Other detailed objects of the invention will be apparent from the following description and the drawing which form this application.

Referring now tothe drawing: Y

Referring to the drawing, B is a bottle o r like container having the customary bead'B to which the commercial caps are secured.r` The` closure member forming the subject matter of thisinvention comprises a pressed metal cap Cv provided with a depending annular flange 1V within which is secured an elasticor compressiblesealing gasket G. 'I'he said ang'efhaslan inwardly pended portion 3 wherein occurs an aperture 4. The portion 3, below said aperture, is outwardly offset at 3 tooier a pivoting'lfulcrum for a cam lever' L, the latter being constructed of ribbon stock, continuously bent-to forman eyelet 5, a nger hold 6y beyond which rthe said stock is shaped to form agnose 7,thatin the sealing position, fits under the bead B' .v before. terminating upon said eyelet outside the aperture 4f.; ,The

which engages the under surface of the bead B when the cap is in position on the bottle.

For removing the cap from' itsposition fon the l bottle the lever L is moved in the direction :of

Similar characters of reference apply to like directedy lip 2 disposed oppositely toa further deinner face ofthe nose '7 forms a cam'lsjurfaceA the arrow in'Fig. 1. This movement causes the] nose 7 to disengage the bead which loosens the cap and permits the same to be removed.

For sealing the cap, the lever is moved in the opposite direction. If during this movement excessive clamping pressure is applied by the lever l0 due to an abnormal size or shape of the bottle neck, the resilient character of the nose 7 will permit the same to be compressed outwardly and thus prevent the breaking of the bottle neck.

Centrally located on the cap C is a spout S having Aa fiat upperplate 8 for the application of thumb pressure, and a downwardly extending shank 9 which extends through a suitable opening 12 in the cap C, Extending downwardly from the base of the shank is a threaded stud 10 70. whichk extends through a central aperture in the gasket Gand to. which a nut l1 is secured, the gasket G .being clamped between the nut and the base of the shank as is clearly shown in Fig. 3.

n Surrounding the shank and'confined between 75 the shoulder 14 on thespout and the cap C is a compression spring 13 normallytending to close the valve about to be described.

The upper face of the nut 11 is provided with an annular groove l5 connecting. with ducts 16 30 i opening `into a oentral'boregl'? which in turn connects with the bore 18`of the spout. Y The spout has a nozzle 19 fordischarging the contents of the bottle. i'

` the plate 8, the inner rim ofthe gasket Gr will be depressed as shown in Fig; 4', thus breaking the seal between the vgasket and the upper face of the nut 10, and permitting ythe. gas from the bot- 90 tlev topass out through the central bore 18 of` thespout. VUpon release of the thumb pressure,

the 'compression in the spring 13 will cause the gasket to return to its original sealing position.`

, Inthemodication shown in Fig. 5, the spring 13 is omitted andthe valve is closed by the resiliency ofV gasketG. In addition, the nut 11' isprovided with a threaded stud 10"which extends into a threaded opening in the shank 9'.. A In otherrespects, the construction is that shown in the form shown in the rst gures.

Having described the invention what is claimed and desired to protect by United States Letters Patent, is1 V 1. A replaceable bottle cap comprising a mey tallic vcup member adapted to extend over the mouth'o'i? the bottle, a gasket disposed between said cap and the mouth of the bottle, an inwardly yextending projection on the side wallof Vsaid cup memberA adapted to engage the neck of the bottle below the bead, compressible cam means secured to said cup member and oppositely disposed from said projection, and means for operating said cam means to cause the same to removably engage the neck of said bottle to permit the insertion and removal of said cap.

2. A replaceable cap for bottles having a bead at the mouth comprising a metallic cup member adapted to be inserted over the neck ot the bottle, a sealing member disposed between said cap and bottle, an inwardly extending projection on the side wall of said cup member functioning to engage the neck of the bottle immediately below the bead, a lever having a return bend portion pivotally secured to said cup member opposite said projection, and a cam surface forming a part of said return bend portion adapted to compressibly engage and to disengage the neck of the bottle upon rocking movement of said lever.

3. A faucet closure for bottles comprising a cap adapted to be inserted over the mouth of the bottle, means securing said cap t-o the bottle, a flat annular gasket disposed between the base of said cap and the neck of the bottle forming a fluid seal for said cap, a spout member extending through said cap and clamped to the inner marginal edges ot said annular gasket, said spout member having passages leading to the interior of the bottle, means cooperating with said annular gasket for normally sealing said passage from the interior of said bottle, and means for deflecting the inner marginal portion of the gasket to thereby open said passages to the interior of the bottle.

4. A valved closure for bottles comprising a cap adapted to be inserted over the neck of the bottle, means for removably securing said cap to the neck of the bottle, a iat annular gasket disposed between said cap and the mouth of the bottle forming a fluid seal for the cap, a spout having a shank portion extending through said cap and abutting the inner marginal edges of said gasket, means for clamping said gasket to said shank, said last named means having upwardly extending passages connected to the bore of said spout, the outlets of said passages being normally sealed by said gasket from the interior of the bottle, and means for defiecting said gasket to open said passages to the interior of the bottle.
