Abstract
Bottle gaskets are provided from a thermoplastic composition comprising a homogeneous blend of butyl rubber with other thermoplastic polymer. The gaskets provide an effective seal at a moderate pressure but permit venting at a higher pressure. They can be made by inserting molten heated thermoplastic material into the bottle cap and moulding it in the cap and cooling it to form the gasket.
