<p>This invention relates to a pressure release apparatus for use in releasing pressure from a pressurised container, such as a pressurised beverage container, and to containers, valve structures or components thereof for the containers comprising a pressure release apparatus. The pressure release apparatus comprises a pressure release passageway to enable venting of the container when the passageway is unobstructed, and a resiliently deformable pressure release member disposed in at least a portion of the passageway, the pressure release passageway defining an external and internal opening and extending through a wall of the container, or a valve structure or component thereof disposed within the container. The resiliently deformable pressure release member and pressure release passageway are shaped to complement one another to enable the pressure release member to be held in the passageway and to seal the passageway when the container is pressurised.</p> |
