Selectively venting and load-sealing closure |
摘要 |
A vented closure, for preventing deformation of a container containing a gas evolving liquid, is provided. The closure includes a first closure member and a second closure member. The first closure member seals the container from the outside atmosphere and defines a gas inlet, a gas outlet and a gas flow passage between the inlet and the outlet. A gas-permeable, liquid-impermeable membrane is placed in the gas flow passage. The second closure member is moveably fitted on the first closure member and encases the first closure member with a small clearance fit that allows gas passage. A sealing element coupled to the second closure member is aligned with the gas outlet of the first member so as to block gas flow when a predetermined load is applied to the second closure member and allow gas flow when the predetermined load is absent.
