    Abstract: A plastics closure for a can end of the kind having a pouring aperture and a venting aperture comprises a first connecting member which connects a vent plug and a pouring aperture plug and is extended to form a pull tab acting directly on the vent plug. The plugs are rupturably sealed over the respective apertures of collar portions connected by a second connecting member and fitting in the venting aperture and the pouring aperture. Flexible tie means extend from the pouring aperture plug to flexible hinges joined to the venting aperture collar. When the pull tab is lifted the vent plug is torn away from the venting aperture collar to achieve dry venting before the pouring aperture plug is torn away to complete opening for pouring. The plugs are retained captive by the tie means for reclosure of the apertures.

    Abstract translation: 用于具有倾倒孔和通气孔的罐端的塑料封闭件包括连接通气塞和倾倒孔塞的第一连接构件,并且延伸以形成直接作用在通气塞上的拉片。 塞子可破裂地密封在由第二连接构件连接的套环部分的相应孔上并且配合在通气孔和倾倒孔中。 柔性系带装置从倾倒孔塞延伸到连接到通气孔口的柔性铰链。 当拉片被提起时,排气塞从通风孔颈环撕开,以便在倒出孔塞被撕开以完成浇口开口之前实现干通气。 插头被紧固装置保持住,用于重新闭合孔。
