Liquid reservoir shutoff vent

Abstract:

A shutoff vent is disclosed. A main body has a first end and a second end. The main body defines a first opening towards the first end, a second opening towards the second end, and a mating port between the first opening and the second opening. The first opening and the second opening are in communication through the mating port to define a gas passageway. A translatable plug is disposed within the main body, and the gas passageway extends past the translatable plug. The translatable plug is configured to reversibly translate towards the second end to sealably obstruct the mating port. In some examples, the translatable plug is configured to translate towards the second end when force is applied to the translatable plug from the first end.
