Alcohol beverage apparatus having a bursting disk

摘要

A beer keg for storing a beer under pressure has an outer wall and a pressure relief passageway extending through an outer wall of the beer keg. The beer keg has a bursting disk seated in the passageway normally closing the passageway. The disk is adapted to rupture permitting fluid to escape from the beer keg through the passageway when the pressure in the beer keg exceeds a predetermined pressure value. The keg has a releasable cap mounted thereto that covers the passageway. The releasable cap has vent openings that permit the escape of fluid from the passageway. The cap is releasable to permit access to the passageway for changing the bursting disk. Preferably, a pressure build up in the keg in excess of about 7 bar results in the bursting disk rupturing.
