ABSTRACT:
A tear open plastics closure for a can end having a pouring aperture and a venting aperture comprises respective annular collar portions fitting in an airtight manner in the apertures and plugs rupturably sealed over the mouths of the collars and capable of being forced back into the collars to re-seal the apertures, the plugs being connected together by a connecting member which is flexibly connected (e.g. by a step piece and a yoke) to one of the collar portions. The connections between each collar portion and the other parts of the closure ensure that the collar portions can tilt and move laterally relative to one another. For example, the collar portions may have no direct connection with one another but be attached solely to the plugs and by the flexible connection of one collar portion to the connecting member. Alternatively they may be connected by a narrow flexible bridge.
