Abstract: A dual sealing system (20) is provided for use with a probe (21) to allow access to an interior space (34) from an exterior environment (32). The system (20) includes a housing (22) defining a port (24) extending along a longitudinal axis (26) between an exterior end (28) of the housing and an interior end (30) of the housing to establish communication between an exterior environment (32) and an interior space (34); a first flexible, resilient penetratable member (40) extending across the port at a first location along the axis, the first penetratable member configured to create a seal around the probe with the probe inserted therethrough; and a second flexible, penetratable member (42) extending across the port at a second location along the axis spaced toward the interior end from the first location, the second penetratable member configured to create a seal after having been penetrated by the probe and the probe has been removed from the second penetratable member.

Abstract: A fluid dispensing valve is provided with a peripheral mounting portion and a connecting sleeve connecting the peripheral mounting portion with a head which defines a dispensing orifice. The valve head includes a recessed exterior surface and an inwardly projecting interior surface. The valve head has a peripheral surface extending from the exterior surface toward the interior surface. The connector sleeve is connected to the valve head at a location that is at the most axially inward extent of the peripheral surface.

Abstract: A fluid dispensing valve is provided with a peripheral mounting portion and a connecting sleeve connecting the peripheral mounting portion with a head which defines a dispensing orifice. The valve head includes a central inner surface portion that bulges axially inwardly to project from a radially outer surface portion.

Abstract: A valve is provided with a peripheral attachment portion by which the valve may be attached to a dispensing structure through which can be discharged a product from a supply of the product. The valve includes a flexible, peripheral sleeve extending from the peripheral attachment portion. The sleeve has a central elongate portion and two shorter end portions at opposite ends of the elongate portion so that the central elongate portion and the two shorter end portions together define an interior volume. The valve also has a flexible, elongate head extending from the peripheral sleeve. The head includes at least one elongate slit defining two, opposed, elongate, openable regions in the head which are normally closed and which open to permit the discharge of the product therethrough in response to a pressure differential across the head.

Abstract: A flow control element is provided with a resilient sealing flange biased to seal in-venting passages in a housing around the element. The element also includes a self-sealing, pressure-openable, dispensing valve. The element and housing can be combined to form a dispensing structure that can function to discharge a fluent material product out of the dispensing structure through the dispensing valve while simultaneously venting exterior ambient air (or other exterior ambient environment fluent material) into the dispensing structure.

Abstract: A valve system is provided with a wall portion that includes an inlet side, an outlet side, at least one aperture extending between the inlet and outlet sides, and a valve seat on the outlet side. One preferred form of the valve system also includes a movable valve member having a spout, a mounting portion, a toggle portion, and at least one seal surface for sealingly engaging the wall portion valve seat when the valve member is toggled to a closed position to prevent flow from the wall portion aperture through the spout.
