ABSTRACT:
This disclosure relates to a closure formed of plastics material for use in conjunction with a container also formed of a plastics material. The closure is particularly adapted for use with containers in the form of bottles which are intended to have a product packaged therein under pressurized conditions. The closure cooperates with a lip of the bottle so as to radially inwardly deform the lip with the exterior surface of the lip forming a seal with the closure. The portion of the closure engaging the lip is drawn radially inwardly under pressure by the axial deformation of an end panel of the closure.
