Container for containing wine, has small sized dent supporting deformation of substantial parts of membrane closure when sufficient difference pressure is applied between inner and outer faces of closure to reduce volume of container space

摘要

The container has a plastic glass containing wine, where the glass is closed by a membrane closure (40) comprising a metal layer. The closure comprises local dents e.g. circular dents (70, 73), where the local dents have symmetry of revolution according to a longitudinal axis of glass. A small sized dent is arranged to support deformation of substantial parts (71, 76) of the closure when sufficient difference pressure is applied between inner and outer faces of the closure, so as to support the total deformation of the closure and to reduce the volume of the space of a head of the container.
