ABSTRACT:
The closure cap of a closure and container package for a pressurized liquid is designed with a sealing flange which depends from the cap top at an angle to a sealing location on the container wall so that an increase in container pressure will increase the sealing force of the flange against the container wall. A pressure relief passage is provided downstream of the sealing location.
