<p>#CMT# #/CMT# 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. #CMT#USE : #/CMT# Container for containing wine. #CMT#ADVANTAGE : #/CMT# The plastic glass is effectively and easily closed by the membrane closure, which allows the better preservation of the wine and provides better comfort for usage of the glass by a consumer. The upper end of an edge or locking ring of the glass comprises an annular rib having a central upper part and two side lower parts extending away from the central upper part, so as to increase a contact surface between the locking ring and a film material used to seal the membrane closure with the ring without increasing the width or thickness of the locking ring, increase the tear strength of the membrane closure, reduce the permeability to the oxygen of the connection zone of the locking ring and the membrane closure and to limit or avoid the presence of projecting remainders after the tearing of the closure. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of a membrane closure. 40 : Membrane closure 70, 73 : Circular dents 71, 76 : Substantial parts.</p> |
