Abstract
A closure (10, 100, 150) for a labware device (20). The labware device (20) defines an interior chamber (25) having at least one opening (92). The closure (10, 100, 150) includes a closure body (12, 102) configured to be mounted to the labware device (20) and in fluid communication with the opening (92). A vent valve (14, 122) is mounted for movement relative to the closure body (12, 102). The vent valve (14, 122), with the closure body (12, 102), defines a space (72, 120) that defines a path between the closure body (12, 102) and the vent valve (14, 122) for gas exchange between the interior chamber (25) and the exterior of the labware device (20). A filter (50) is positioned within the space (72, 120) and is configured to filter contaminants from gas entering the interior chamber (25) via the path.
Claims7
A closure for a labware device defining an interior chamber and having at least one opening in fluid communication with the interior chamber, the closure comprising:
- a closure body configured to be mounted to the labware device and in fluid communication with the at least one opening, the closure body having a venting region, an outer sidewall and an inner sidewall operably coupled to the outer sidewall by the venting region;
- a vent valve mounted within the closure body for upward and downward movement relative to the closure body and defining a space between the closure body and the vent valve, the space defining a path between the closure body and the vent valve for gas exchange between the interior chamber and the exterior of the labware device through the venting region of the closure body, wherein the venting region comprises a plurality of openings in communication with the space and the vent valve includes at least one boss thereon, and the venting region having a shape defining a plurality of positions, each of the plurality of positions being shaped to engage the least one boss of the vent valve;
- and
- a filter positioned within the space and configured to filter contaminants from a gas entering the interior chamber via the path.
A closure for a labware device defining an interior chamber and having at least one opening in fluid communication with the interior chamber, the closure comprising:
- a closure body configured to be mounted to the labware device and in fluid communication with the at least one opening, the closure body having a venting region, an outer sidewall and an inner sidewall operably coupled to the outer sidewall by the venting region;
- a vent valve mounted within the closure body for upward and downward movement relative to the closure body and defining a space between the closure body and the vent valve, the space defining a path between the closure body and the vent valve for gas exchange between the interior chamber and the exterior of the labware device through the venting region of the closure body, wherein the vent valve includes at least one recess on an external surface thereof, and the inner sidewall of the closure body further includes at least one inwardly directed tab configured to be received by and move within the at least one recess;
- and
- a filter positioned within the space and configured to filter contaminants from a gas entering the interior chamber via the path.
