(EN) 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 theclosure (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 theventing aperture (27) is no longer sealed by the barrier (29).
(ZH) 一种用于饮料桶(90)的封闭件(1)，包括用于允许加压气体进入饮料桶(90)的顶部空间的入口和与入口分离的通气孔(27)。通气孔(27)被构造成在桶(90)的顶部空间与封闭件(1)的外部之间提供流体连通。封闭件(1)设有阻挡件(29)，该阻挡件焊接到封闭件(1)并被构造成密封通气孔，使得封闭件(1)在不通气构造时能够将加压气体保持在桶(90)内。阻挡件(29)被构造成通过来自桶(90)内的内部压力破裂和/或至少部分地与封闭件(1)分离，以便将封闭件(1)切换到通气构造，在通气构造中，通气孔(27)不再由阻挡件(29)密封。
