VALVE DEVICE FOR FLUID STORAGE AND DISCHARGE Russian patent published in 2013 - IPC B67D1/04 

FIELD: transport, distribution.

SUBSTANCE: invention relates to carbonated beverage dispensers. Proposed container comprises dispensing tube and cover secured at neck composed of a cap with bore at its end. Valve device consists of connected cylindrical first and second parts and annular valve. First part serves to retain valve device components while second part retains the container and seals it. Said first part has bottom and tubular element for dispensing tube. Besides its has barrel for attachment in tubular element with flanging at bottom location and fluid passage openings at the surface for guiding the spring thrusting against the first part bottom. Cutouts are made on second part inner surface. First part bottom has openings for feeding carbonic acid and discharge therefrom. Valve is arranged between second part inner surface and barrel surface and has side surfaces. First surface has extending mid section and thrust parts to interact with flanging of second part inner surface and barrel. Valve second surface has stiffness ribs and annular chamber to receive the spring and to press valve thrust surfaces against said second part inner surface flanging and barrel. Valve is made from elastoplastic with Shore hardness of 69-75 by injection moulding. Valve outer and inner surfaces interacting with second part inner surface and barrel cylindrical surface are tapered while cap is fitted flush with second part to thrust against the ledge made at second part outer surface.

EFFECT: better storage and dispensing, simplified fabrication.
