Abstract: A container assembly includes a vessel and a lid removably coupled to the vessel. The lid includes a circumferential rim at an interface with the vessel, wherein the rim is separated from the vessel by a gap, wherein the gap is open to the atmosphere outside the container. The container includes a gasket disposed at a sealing position between the lid and the vessel to seal a reservoir of the vessel from the gap. The rim includes a recess extending circumferentially along a first portion of the rim. The recess forms a portion of the gap and defines a venting zone extending circumferentially along the first portion of the rim. In response to the internal reservoir of the vessel reaching a threshold pressure, a portion of the gasket moves from the sealing position through the gap such that fluid held in the reservoir is vented past the gasket through the venting zone to reduce the pressure of the reservoir.

The cap body includes a cylindrical receiving portion which has a cylindrical shape about the screw axis. A seal-receiving portion receiving a seal member held between the cap body and an oil filler port portion is provided on an outer circumferential surface of the cylindrical receiving portion. A valve-receiving portion receiving the valve device inserted into an inner circumference of the cylindrical receiving portion is provided on an inner circumferential surface of the cylindrical receiving portion.

Abstract: The object of the present invention is to provide a sealing structure which enables an insertion member to be removed easily from an inserted member. The sealing structure includes valve body, a mouth ring, an O-ring that is accommodated in an accommodation region formed by an inner peripheral surface of the mouth ring and an outer peripheral surface of the valve body, and prevents the fluid from leaking, and backup rings which are accommodated on both sides of the O-ring in the accommodation region, and restrict a movement of the O-ring. The valve body and the mouth ring are formed with screw parts to be fitted or screwed to each other when they are assembled, and first pressure release grooves are formed in the axial direction so as to extend at least on the inner peripheral surface of the mouth ring between the screw parts and the accommodation region.

Abstract: According to the invention a drinking vessel (10) comprises a generally cylindrical container (11) adapted to contain liquid and a generally cylindrical lid (12) adapted to close the container. The lid comprises a generally cylindrical outer member (20), a generally cylindrical inner member (22) located within the outer member so as to define a generally cylindrical aperture (50) between the outer surface of the inner member and the inner surface of the outer member, and a generally cylindrical sealing element (21) located in the aperture. The sealing element normally forms a seal between the outer surface of the inner member and the inner surface of the outer member but is deformable by suction at the end of the aperture remote from the container so as to cause liquid within the container to flow, from the end of the aperture adjacent to the container, out through the aperture under the action of the suction.

Abstract: A closure lid for a connecting element of a computer container, comprising an inner part which is maintained on an outer part of said lid and which is provided with an annular groove on the outer periphery thereof, said groove being defined by an annular web on the outer side of the lid and having a sealing ring inserted therein. In order to provide a closure lid which is embodied in such a way that it is possible to prevent the sealing ring from being raised radially from the base of the groove as a result of existing pressure and therefore to relieve the pressure inside the container before the open position of the closure container is reached, the annular web disposed on the outer side of the lid is provided with an uneven bearing surface for the sealing ring.

Abstract: According to the invention a drinking vessel (10) comprises a generally cylindrical container (11) adapted to contain liquid and a generally cylindrical lid (12) adapted to close the container. The lid comprises a generally cylindrical outer member (20), a generally cylindrical inner member (22) located within the outer member so as to define a generally cylindrical aperture (50) between the outer surface of the inner member and the inner surface of the outer member, and a generally cylindrical sealing element (21) located in the aperture. The sealing element normally forms a seal between the outer surface of the inner member and the inner surface of the outer member but is deformable by suction at the end of the aperture remote from the container so as to cause liquid within the container to flow, from the end of the aperture adjacent to the container, out through the aperture under the action of the suction.

Abstract: A filter pump cover according to the invention comprises a filter cap, an air purge valve, and a filter cap retainer. An air purge valve according to the invention is comprised of a valve cap, a screw-threaded portion, and a valve stem having one or more outward-facing inverse hooks at the bottom. The inverse hooks are located at the bottom of the air purge valve stem and hook onto the bottom lip of the hollow central portion of the filter cap retainer to prevent complete removal of the valve stem from the filter cap retainer. The valve screw-threaded portion is interrupted by a valve opening slot on one side that permits the release of air from the pump when the valve is opened. The hollow part of the filter cap retainer mates with and holds the air purge valve by means of the screw threads when the valve is closed.

Abstract: A circular seal (19) for the end face of a substantially cylindrical canister, the seal (19) having a substantially rectangular cross-section, and a recess (21) in one side thereof to reduce the area of said cross-section. In use the recessed area (21) of the seal (19) constitutes a weakened portion which will blow out elastically to relieve excess pressure.

Abstract: The invention relates to a sealing cap (11), for openings and containers. The valve arrangement (15) comprises an axiallly displaceable valve body (17), which is held in the direction of the container interior by means of a spring (22) against a first sealing seat (34), on the cap interior. The valve arrangement (15) comprises one single valve body (17), provided with a first axially effective sealing surface arrangement (20) and a second radially effective sealing surface arrangement (21). The axially effective sealing surface arrangement (20) co-ordinates with an axial seal seat (34), surrounding a defined opening (32), connecting to the container interior on the cap inner part (14). The radially effective sealing surface arrangement (21) co-ordinates with a first radial counter sealing surface (61, 62), comprising a bypass (39), for the first flow connection and a second radial counter sealing surface (61), comprising a safety relief opening (69), for the second flow connection.

Abstract: An indexing safety gasket (1) designed to be mounted in the lid of a pressure cooker for the purpose of providing sealing at pressure between the lid and the pan of the pressure cooker, the gasket being characterized in that it includes at least one outer notch (25) in its periphery, and means for fastening the gasket (1) relative to the lid so as to index rotation of the gasket (1) to rotation of the lid.

Abstract: A membrane type pressure relief valve for packaging containers. The valve comprises a plastic overlay that is formed in a way that causes the center portion of the valve to be pre-stressed when applied to a base sheet or a package wall. The forming of the overlay and its subsequent deformation after application to the base sheet or package wall causes the overlay to act as a mechanical assist to close the valve when the valve oil does not fully force the valve closed.

Abstract: The invention is a cap engagable with a filler neck of a vehicle fuel tank, the cap having a core including an axially lower end, an axially upper end, and an exterior side wall extending between the axially lower and upper ends. A handle is coupled adjacent the axially upper end of the core and adapted to rotate the core about an axis of rotation between a loosened position permitting removal of the core from the filler neck and a tightened position securing the core within the filler neck. The cap further includes a seal positioned to lie around the core and a sleeve movable axially by the handle. The sleeve and has an interior side wall defining a chamber formed in the sleeve. The core lies within the chamber, and the seal lies between the sleeve and the core.
