Closure for a container having vent and tethered means

摘要

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.
