Title: COLLAPSIBLE CONTAINER WITH DISPENSING VALVE, ESPECIALLY FOR BEER
Abstract:
A soft-walled plastics bottle (B) for beer, or another carbonated beverage, is fitted at its neck with a flow-controlling device comprising a non-return valve which prevents the beverage being dispensed except under pressure exerted by squeezing the bottle. The valve, which comprises a displaceable body (108) which is urged into engagement with a seating (130) by a spring (106), serves to prevent air entering the container and also provides for the beverage to be forced under pressure through an orifice into an expansion chamber (170) before being dispensed. In the case of beer, such treatment of the beer can result in a desirable de-carbonation and the formation of a good head on the beer.
