Abstract
The present invention relates to an extractor tube assembly for a beverage container, comprising a gas valve and a beverage valve adapted to cooperate with each other, the gas valve and beverage valve comprising a ring-shaped gasket, the gasket being made of an elastomeric material and comprising an insert made of a rigid material, and the gasket having a top part with an upper face visible from outside the extractor tube assembly, the top part being arranged above the insert. The elastomeric material encloses the insert and a portion of the top part of the gasket is adapted to be released from the insert when a pressure inside the beverage container exceeds a predetermined level so that fluid communication between an interior of the beverage container and the surroundings is provided, whereby the pressure is released from the beverage container, the gasket comprising an identification detectable from the upper face of the gasket, so that it is easily detectable if a pressure release function of the gasket has been partly or fully initiated.
