AT TORNEYS Patented Mar. 18, 1930 UNITED STTE ATET OFFICE FAIRFIELD W. I-IOBAN, OF NEW YORK, N. Y.; ASSIGNOR TO FAIRFIELID SPECIALTIES CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK VALVE-CONTROLLED CLOSURE FOR BOTTLES CONTAINING CARBONATED BEVERAGES Application filed May 31, 1928. Serial No. 281,735.

My invention relates to means for closing or sealing the mouths of containers or bottles for carbonated beverages, such as ginger ale, vichy and the like, and the same has for its object more particularly to provide a simple, durable and efiicient device which may be readily applied to the end of the container or bottle to replace the ordinary cap or stopper therefor when the same is removed,

and which may be readily actuated to open the same to permit of the discharge of the contents of the bottle, and to close the same to prevent such contents from becoming Another object of the invention is to provide a device of the character specified in which the valve means for controlling the discharge orifice of the device is disposed entirely within the confines of a member having wall portions impervious to air, and capable of engaging the neck of the bottle to provide an air tight cap or closure therefor.

Another object of the invention is to provide a device of the character specified in which the valve means thereof is actuated by depressing or deforming portions of the cap or closure receiving the same.

F urther, said invention has for its object to provide a device of the character specified in which the controlling means for the discharge orifice thereof is disposed to become increasingly eflective in sealing said orifice as the pressure within the container increases.

Further, said invention has for its object to provide a device of the character specified in which the body portion thereof is composed of a molded substance impervious to inposition .to permit of the actuation of the the wall portion of the valve-by; depressing cap or" closure;

air and capable of yielding toform air-tight. closure or cap for the container or bottle,

Other objects will in part be obvious and in part be pointed out hereinafter.

To the attainment of the aforesaid objects and ends, my invention consists of the novel features of construction, and in the combination, connection and arrangement of parts hereinafter more fully described and then pointed out in the claims.

In the accompanying drawing.

Referring to the drawing, the device 10,

. shown at Fig. 1 applied to the open end ofthe bottle 12, consists of a stopper or closure 14, preferably in the form of a cap, including a lower portion 16 having a relatively deep open recess 17 therein shaped and designed to receive the neck of the bottle, and to fit the same closely, forming an air-tight oint. The upper portion ortip 18 of the member 14 is provided with a discharge orifice 20, preferably reinforced by a metallic sleeve 22 disposed therein, and communicating with the interior of the device. The lower projecting portion of the sleeve 22 has a shoulder 24 engaging the portion 18 and an'annular end or entrance portion 26.

The upper portion 18 of the member 14 is provided with projecting portions 28 located at diametrically opposite points substan tially on a line with ora little above the annular inner end 26 of the discharge orifice, and providing interior recesses 30 extending outwardly from the portion of the recess 17 adjacent to the annular portion 26 above the end of the bottle.

The member or closure 14 preferably con sists of a molded composition, such as rubber or rubber composition, which is sufficiently" yieldable to fit tightly around the bottle, and is impervious to air and other: gase's'.--- The ably of reduced thickness to render the same more yieldable than the remaining portions of the device to permit of the same being readily depressed or deformed by the fingers for the, purpose of actuating the valve means 32 as hereinafter described. Further, the entire member, including the portions 16, 18 and 28, are integrally formed, and the wall portions thereof, except for the discharge oririce 20 and the opening for the bottle, is imperforate throughout to provide an absolutely air-tight closure for the bottle. 7

The discharge orifice 20 is controlled by the valve means 32 disposed entirely within the confines of the device at the upper end of the recess 17. The valve means includes an elongated, naturally straight member or'strip 34, composed of a. material capable of being flexed, such as rubber, a rubber compound or the like. i

The member 34 is disposed.transversely of the device centrally across the recess 17 to i leave passages at opposite sides thereof, and

with the ends'35 thereof received within the recesses upon the inwardly and downward ly inclined ledge portions 36, the member 34 being retained against displacement by the walls of the portions 28. A plate or valve portion 38 carried by the member 39 is adapted to engage and seat upon the edge of the annular entrance 26' to close the discharge orifice 20. The member 34 has the ends thereof retained at a slightly higher elevation than the central portion thereof, by the engagement of the plate 38 with the annular portion 26,]whereby to maintain the member 34 normally bowed under tension, exerting a spring action on the plate 38 to retain the plate in engagement with the edge of the entrance portion 36.

The valve portion 38 is composed of a material capable of yielding when engaged by the edge of the annular portion 26 to provide an air-tight closure, said portion 38 however 1 having suflicient, inherent rigidity to maintain its configuration when disengaged from its seat. For constructional purposes, the plate or valve 38 is preferably formed integrally with the resilient supporting member 34 to provide an element of homogeneous composition. The plate 38 is preferably connected to the member 34 by a flexible stem or neck 40 to permit of the plate seatingeven- 1y when the same engages the annular portion 26. 1 NVhen it is desired to preserve the strength of the carbonated liquid contents of a bottle afterthe ordinary cap or closure thereof is removed, my'device may be readily disposed over the end of the bottle to closely fit'the same. The member '34, which is normally maintained under tension because of the ele vated position-of the ends 35 thereof relative to the central artjthe reof, tends-t9 straighten out whereby to effectively force the plate 38 under spring pressure against the edgeof the portion 26, the latter biting into the yield able material of the plate to form a very tight joint. The gas pressure within the bottle also supplements the member 34 in maintaining the valve 38 seated, the greater this pressure the greaterthe force acting on the valve to retain the same seated.

The'device 10, therefore, providesan absolutely air-tight closure for the bottle, and maintains the contents in their original condition for a considerable period of time, without the same becoming flat. When the contents of the bottle are required for use, the bottle is inverted and the portions 28 are depressed by the fingers as shown at Fig. 4 to further bow'the spring member 34 and'to move the plate 38 to open the discharge orilice 20, whereby to discharge the contents from the bottle. By first shaking the bottle, the contents thereof, when the valve is opened, will be ejected with considerable force, due to the pressure developed by the release of part of the carbonic acid gas from the liquid. Upon release of" the portions 28, the parts return, because of the resiliency thereof, to closed position as shown at Fig. 2. g

By my invention, I provide'a device which comprises two main parts, preferably of molded, yieldable or flexible material, which are readily assembled. The cap portion therefor forms an absolutely tight closure,

the cap or closure itself. My device is therefore absolutely devoid of actuating parts passmg through openings in the wall portion thereof, whereby to obviate possibility of leakage. t

The valve means is also constructed to normally effectively seat under the action of the member 34 to form a tight closure for the discharge orifice, the seating of the valve and the centering thereof being most efiective because of the yieldabil-ity of the valve plate 38 and the flexibility of the stem-4O connecting said plate to the transverse'member 34.
