The invention relates to a valve (1) for mounting to a surface (2) and for use in a flow path, which flows through said surface (2), for permitting flow in said flow path in a first direction and for preventing flow in said flow path in a second direction being opposite to the first direction. The valve (1) comprises: one or more ports (21) defined by a plurality of lips (22), wherein each lip (22) is resiliently deformable from a first position, in which the lips (22) are in contact with one another in order to close the respective port (21), to a second position, in which the respective port (21) is opened in order to permit flow in the first direction, and one or more contacting structures (30) arranged to mechanically contact the surface (2), when the valve is mounted to the surface (2), such that the one or more contacting structures (30) bias the lips (22) into the first position.

A fluid directing flow manifold for directing reactive fluids, independent of one another, from a dispensing manifold to a dispensing tip of a fluid dispensing apparatus provides a disposable and low cost fluid passageway between the dispensing manifold and dispensing tip while reducing or eliminating the possibility that reactive fluids will react and clog or block the dispensing manifold. The flow manifold provides independent fluid passageways between valves of a dispensing manifold and a mixing chamber of a dispensing tip of the dispensing apparatus. The flow manifold may be adapted for use with various types of fluid dispensing systems. The flow manifold may include multiple fluid guide bodies that may each be removed from the flow manifold to be cleaned or disposed of, and then replaced. Quick release mechanical fasteners are included for quick attachment of the manifold to a dispensing manifold valve and to the dispensing tip.

A degassing unit for an electronics case includes a base body attachable to the electronics case and configured to seal against a perimeter of an aperture in the electronics case, the base body including a degassing opening, a membrane covering the degassing opening of the base body and including at least one segmentation line penetrating through the membrane, and at least one support rib abutting adjacent segments of the membrane along the at least one segmentation line. Each of the membrane and the at least one support rib has a convex shape facing away from the base body.

The present invention relates to sealing valves that can be mounted within a container wall, enabling controlled fluid flow along both inner and outer surfaces of the sealing valve in the same distal direction.

Methods and systems include a check valve including a valve body formed from a resilient material, the valve body having an inlet side and an outlet side. The valve body includes a rim forming an outer periphery of the valve body, and a hinge section comprising an annular groove formed on the inlet side of the valve body radially inward of and adjacent to the rim. The valve body also includes a plurality of lips formed at a center of the valve body by one or more slits extending radially outward from the center of the valve body towards the hinge. The hinge section is co-planar with the plurality of lips when in a closed position.

A sealing member for providing a seal between fluid connectors includes a tubular member defining a lumen extending between a first end and a second end. The tubular member may receive a first connector via the first end and a second connector via the second end, and includes an annular wall extending between a first annular portion adjacent the first end and a second annular portion adjacent the second end. The first annular portion may engage the first connector, and the second annular portion may engage the second connector. When a pressure within the lumen is negative, atmospheric acting inward on the annular wall compresses the sealing member to define a contact force between the second annular portion and the second connector sufficient to define a fluid seal between the sealing member and the second connector.

A chalk port for retaining chalk within a chalk reservoir of a chalk box may include an interface portion configured to interface with a housing of the chalk box to retain the chalk port in contact with the chalk box, a tapered portion extending away from the interface portion in an axial direction, and a slit assembly disposed at the tapered portion. The tapered portion may have a diameter that reduces as distance from the interface portion increases. The tapered portion may include a plurality of projections separated from each other by slits of the slit assembly. The projections may have a rest position configured to bias the slit assembly closed. Ribs may be formed to extend between the interface portion and the projections to bias the projections to the rest position.

A fluid connector system includes a first connector adjoining a second connector at a junction, and a sealing member coupled to the first connector and the second connector around the junction. The sealing member can include an annular wall having a first annular portion configured to engage the first connector and a second annular portion configured to engage the second connector. The sealing member can include an annular chamber extending between the first annular portion and the second annular portion. The annular chamber can be formed by the first annular portion sealing against an outer surface of the first connector and the second annular portion sealing against an outer surface of the second connector when a pressure between the sealing member and the first connector and the second connector is negative.

A TPE valve (20, 20A) includes a head (125, 125A) with a central axis (43) and has an interior surface (130, 130A, 132, 132A, 133, 133A), an exterior surface (134, 134A), and at least one self-sealing slit (140, 140A). The valve (20, 20A) includes a peripheral attachment portion (120, 120A) spaced laterally from the head (125, 125A) and an intermediate portion (124, 124A) extending laterally from the head (125, 125A) to the peripheral attachment portion (120, 120A). The intermediate portion (124, 124A) has an interior surface (126, 126A) and an exterior surface (127, 127A). The interior surface (130, 130A, 132, 132A, 133, 133A) of the head (125, 125A) and the interior surface (126,126A) of the intermediate portion (124, 124A) intersect at a first circular line of intersection (150, 150A). The exterior surface (134, 134A) of the head (125, 125A) and the exterior surface (127, 127A) of the intermediate portion (124, 124A) intersect at a second circular line of intersection (154, 154A). The first circular line of intersection (150, 150A) and the second circular line of intersection (150, 150A) are spaced an axial distance no greater than about 0.30 millimeter.
