Container for storing a liquid, pressure valve therefor and use of the container as a beer barrel; method for controlling the pressure in a container of this type; hollow container base, modular system for producing a hollow container base and method for filling a container

Abstract

A container whose content can be removed easily by a consumer. The container should be inexpensive to produce while being extremely easy to operate by the consumer, should provide a high degree of flexibility with respect to the choice of the propellant gas (pressure and type of gas) and should achieve a long storage life for the contents, even after the container has been tapped. The container comprises a fill chamber (), a pressure chamber () and a pressure valve (). The fill chamber () is formed by a container base (), a container wall () and a container upper face (), and a first pressure (p) prevails in the fill chamber (). The pressure chamber () is formed by the container base () and a pressure chamber base () and a second pressure (p) prevails in the pressure chamber (). The pressure valve () is connected to the container base () and the pressure chamber base (). The pressure valve (), when open, establishes fluid communication between the fill chamber () and the pressure chamber (), and the pressure valve (), when closed, separates the fill chamber () and the pressure chamber () in a fluid-tight manner from one another.
