Abstract
The present invention relates to sealing valves that can be mounted between two container walls, enabling controlled fluid flow along the inner surfaces of each of the container walls, separately.
Claims20
A tubular seal for sealing between a wall and a cover of a cylindrical container, wherein the seal extends around a centerline and longitudinally between a proximal end and a distal end, wherein the seal comprises:
- a membrane juncture extending around the centerline;
- a first membrane extending distally from the membrane juncture;
- a second membrane extending radially inward from the membrane juncture;
- and
- an anchoring membrane extending radially outward from the membrane juncture;
- wherein when the seal is positioned between the wall and the cover and no pressure is applied there against, each of the second membrane and the anchoring membrane is configured to seal against the cover, and the first membrane is configured to seal against the wall;
- wherein the first membrane is made of a resilient flexible material so as to bend inward toward the centerline when flow-induced pressure gradient is applied thereto by fluid flowing in the inward direction and to spontaneously restore the sealing against the wall, when the flow-induced pressure gradient ceases;
- and the second membrane is made of a resilient flexible material so as to bend distally when flow-induced pressure gradient is applied thereto by fluid flowing in the distal direction and to spontaneously restore the sealing against the cover, when the flow-induced pressure gradient ceases.

A sealed container, comprising:
- a cylindrical vessel comprising:
- a vessel floor, a vessel cover positioned parallel thereto, and a cylindrical vessel wall positioned perpendicular to the vessel floor and vessel cover, defining an internal cavity, wherein the cover comprises at least one cover opening and wherein the wall comprises at least one wall opening;
- and
- a tubular seal positioned between the vessel cover and the vessel wall;
- wherein the seal is coaxial with the vessel and extends around a centerline and longitudinally between a proximal end, which is in contact with the vessel cover and a distal end within the internal cavity;
- wherein the seal comprises:
- a membrane juncture extending around the centerline and in contact with the vessel cover;
- a first membrane extending distally from the membrane juncture and sealing against the at least one wall opening;
- a second membrane extending radially inward from the membrane juncture and sealing against the at least one cover opening;
- and
- an anchoring membrane extending radially outward from the membrane juncture out of the internal cavity;
- wherein the first membrane is made of a resilient flexible material so as to bend inward toward the centerline when flow-induced pressure gradient is applied thereto by fluid flowing in the inward direction through the at least one wall opening and to spontaneously restore the sealing against the at least one wall opening, when the flow-induced pressure gradient ceases;
- and the second membrane is made of a resilient flexible material so as to bend distally when flow-induced pressure gradient is applied thereto by fluid flowing in the distal direction through the at least one cover opening and to spontaneously restore the sealing against the at least one cover opening, when the flow-induced pressure gradient ceases.
