Title: KEG CLOSURE WITH ATTACHED VENTING SYSTEM
Abstract:
A closure (1) for a beverage keg (90), comprising an inlet for admitting a pressurised gas into a headspace of the beverage keg (90) and a venting aperture (27) separate from the inlet. The venting aperture (27) is configured to provide fluid communication between the headspace of the keg (90) and an exterior of the closure (1). The closure (1) is provided with a barrier (29) that is welded to the closure (1) and configured to seal the venting aperture such that the closure (1) is able to retain the pressurised gas within the keg (90) in an unvented configuration. The barrier (29) is configured to rupture and/or to become at least partially detached from the closure (1) by internal pressure from within the keg (90) in order to switch the closure (1) into a vented configuration in which the venting aperture (27) is no longer sealed by the barrier (29).
