Abstract
There is provided breathable overpressure assemblies that are secured to a sealed container and configured to rupture in the event of a rapid pressure increase and to regulate pressure inside the container. A breathable overpressure assembly includes a rupture member having a central rupture portion and a peripheral flange extending about at least a portion of a periphery of the central rupture portion. The breathable overpressure assembly includes at least one vent opening in at least one of the central rupture portion and the peripheral flange, and a breathable membrane that covers the at least one vent opening.
Claims23
A breathable overpressure assembly for being mounted over an opening in a sealed container, the breathable overpressure assembly comprising:
- a rupture member including a central rupture portion and a peripheral flange extending about at least a portion of the central rupture portion, the central rupture portion sized to cover the opening in the sealed container and configured to rupture at a predetermined pressure at an interior container side of the rupture member;
- at least one vent opening extending through at least one of the central rupture portion and the peripheral flange;
- and
- a breathable membrane covering the at least one vent opening for allowing the passage of gas through the at least one of the central rupture portion and the peripheral flange via the breathable membrane,
- wherein the at least one vent opening includes a plurality of vent openings, and the breathable membrane includes at least one breathable membrane that covers the plurality of vent openings.
A breathable overpressure assembly for being mounted over an opening in a sealed container, the breathable overpressure assembly comprising:
- a rupture member including a central rupture portion and a peripheral flange extending about at least a portion of the central rupture portion, the central rupture portion sized to cover the opening in the sealed container and configured to rupture at a predetermined pressure at an interior container side of the rupture member;
- at least one vent opening extending through at least one of the central rupture portion and the peripheral flange;
- and
- a breathable membrane covering the at least one vent opening for allowing the passage of gas through the at least one of the central rupture portion and the peripheral flange via the breathable membrane,
- wherein the at least one vent opening is in the peripheral flange and includes a plurality of vent openings, and the peripheral flange includes at least one fastener opening disposed between a pair of the vent openings for receiving a fastener therethrough.
A breathable overpressure assembly for being mounted over an opening in a sealed container, the breathable overpressure assembly comprising:
- a rupture member including a central rupture portion and a peripheral flange extending about at least a portion of the central rupture portion, the central rupture portion sized to cover the opening in the sealed container and configured to rupture at a predetermined pressure at an interior container side of the rupture member;
- at least one vent opening extending through at least one of the central rupture portion and the peripheral flange;
- and
- a breathable membrane covering the at least one vent opening for allowing the passage of gas through the at least one of the central rupture portion and the peripheral flange via the breathable membrane;
- and
- a gasket having a plurality of fastener openings and a plurality of vent openings extending therethrough, wherein the at least vent opening of the at least one of the central rupture portion and the peripheral flange comprises a plurality of vent openings of the rupture member, the rupture member includes a plurality of fastener openings, and the plurality of fastener openings of the gasket are generally aligned with the plurality of fastener openings of the rupture member, and the plurality of vent openings of the gasket are generally aligned with the plurality of vent openings of the rupture member and the breathable membrane.
A breathable overpressure assembly for being mounted over an opening in a sealed container, the breathable overpressure assembly comprising:
- a rupture member including a central rupture portion and a peripheral flange extending about at least a portion of the central rupture portion, the central rupture portion sized to cover the opening in the sealed container and configured to rupture at a predetermined pressure at an interior container side of the rupture member;
- at least one vent opening extending through at least one of the central rupture portion and the peripheral flange;
- and
- a breathable membrane covering the at least one vent opening for allowing the passage of gas through the at least one of the central rupture portion and the peripheral flange via the breathable membrane,
- wherein the central rupture portion includes a frangible portion along which the central rupture portion ruptures, and the at least one vent opening includes a first vent opening and a second vent opening with the frangible portion extending therebetween.
