Pre-threaded container closure.

摘要

A container closure, in this case a bottle cap 1, has a flowed in gasket 2 which engages the neck rim 5 of a bottle to generate sealing contact over the inner corner of the neck rim, substantially without contact of gasket material with the outer corner. The co-operation of the neck rim and gasket may be by virtue of shaping of the gasket 2 and/or shaping of the bottle cap end panel 3, and/or shaping of the glass finish of the bottle neck rim.
