VENT ASSEMBLY AND RESERVOIRS INCLUDING THE SAME

摘要

Vent assemblies movable between a vented position and a non-vented position are described along with reservoirs in which the vent assemblies may be used. The vent assemblies each include an aperture and a closure member. The closure member is configured for movement along a cam surface to generate a compressive force such that a sealing surface on the closure member is forced against the wall of the reservoir and over the aperture such that the vent assembly is in the non-vented position. The closure member movement may be, e.g., rotational or linear (i.e., translational) when moving between the vented and unvented positions.
