Abstract: A cap with a way-one valve solves two distinct problems in the field of packaging materials that emit gasses, providing both a means to prevent a package from deforming under pressure built up inside the package, and a means to reseal the package. The cap comprises an inner wall extending downwardly from an inner portion of the top wall to define a cavity. An insert valve is mounted within the cavity, forming a seal with the inside wall. The upper surface of the insert valve, inner wall, and the top wall define a chamber with a gas escape path. A septum is disposed within the chamber, the septum seated on the insert valve and sealing one or more apertures in the insert valve. The septum is capable of at least partially unseating in response to force exerted by increased gas pressure acting through the apertures.

Abstract: A lid (10) for a saucepan includes a glass or plastics cover (11) having an opening (23) and a disc (14) secured to the cover and extending across the opening. The disc has a steam aperture (17) through which steam from the saucepan can escape. A handle (13) is secured to the cover by attachment to the disc. The arrangement provides increased strength as compared to a glass or plastics lid having a steam release aperture formed directly in it. The disc (14) can be removed from the opening for cleaning purposes.

Abstract: A kind of sealing valve for vacuum container comprising: the cap body, the connecting body and the locking portion; the cap body is to be jointed to the locking portion through the connecting body; the locking portion is formed with the concave portion; the locking portion is to lock onto the hole on the upper cap via the concave portion, thus when the vacuum pump proceeds to extract air out of the vacuum container, the cap body is to be deflected and deformed by air flow, so that the air hole of the upper cap is to be opened, and then the cap body is to automatically close the air hole of the upper cap after the pressure difference between the interior and exterior of the vacuum container has reached the predetermined value.

Abstract: A sports bottle cap having a pressure differential valve is provided which allows water to flow out through the bottle cap only when the bottle is inverted and squeezed or alternatively a straw may be threaded through the pressure differential valve, thereby deactivating it, and attached to the bottle cap allowing the user to draw liquid from the bottle through the straw. In operation the bottle cap of the present invention allows the user to dispense fluid from within the bottle in two different ways. The first manner of use allows liquid to be dispensed only when the bottle containing the liquid is inverted and squeezed. Squeezing causes the pressure to increase on the inside of the bottle thereby causing the pressure differential valve to open and liquid to exit; however, when the bottle is not squeezed the pressure differential valve remains in the closed position sealing bottle.

Abstract: A shipping container with an outer shipping container shell and a support assembly for holding a dewar vessel within the outer shipping container shell and providing impact and vibration resistance to the dewar vessel. The dewar vessel has an inner vessel that holds a specimen chamber and plastic foam between its inner wall and the specimen chamber. The specimen chamber allows liquid cryogen to pass through it into the plastic foam, allows liquid cryogen in a vapor phase liquid state to pass from the plastic foam into it, and acts as a filter to prevent particles or fragments of the plastic foam from entering into it. The specimen chamber is an open-celled porous thermoplastic material that is cryogenically compatible such as an aerated polypropylene foam. The plastic foam is an open cell plastic foam such as a phenolic foam. The plastic foam can hold a normal charge of liquid cryogen in a dry vapor state regardless of the container's spatial orientation.

In a closure member attached with a finger grip portion and fitted over the opening of a container body, the finger grip portion includes a finger grip main body having a lower portion formed with an engagement portion that is inserted into a through-hole of the closure member while ensuring air communication through the through-hole, and a cylindrical outer cover portion formed from a flexible material and circumscribing the finger grip main body.

Abstract: The microwavable shipping and/or retail package described here for heating food includes a material suitable for use in a microwave oven. The food disposed in the package is preferably at least partially raw. Taking into account the water content of the food, enough liquid is present in the package for the food to be cooked in a steam atmosphere which develops in the package when heated in a microwave oven. The package has a one-way valve in a wall, which opens automatically to the outside when there is an internal excess pressure, then closes again automatically after the pressure drops, thus limiting and/or reducing the vapor pressure that develops in the package during heating in a microwave oven. The valve membrane may automatically open and automatically close until the membrane deforms during heating, thereby causing said valve to remain open.

Abstract: A vapor directing baffle for a beverage container. The combination of a beverage container and a tight fitting lid in combination with an internal baffle forces aroma laden vapor (located between the interior of the lid and the liquid surface of the beverage in the container) outward through openings in the lid, when the beverage container is tipped from the level position to the drinking position. This vapor pumping action places the outwardly flowing aroma beneath the nose of a user, thereby allowing the user to enjoy the aroma of the beverage.

Abstract: The present invention relates to a rotatable cover which can be screwed or plugged on and is to be fastened on a stationary connection of a motor vehicle radiator or compensator reservoir of cooling and heating systems. The cover has a screw or plug cap and/or swivel cap and a rotatable engagement part in which a valve in the form of a combined overpressure/underpressure unit is arranged concentrically. The valve has a sealing member which produces a sealing connection with the stationary connection when the cover is applied. When the cover is positioned on the stationary connection, it is possible to prevent by means of a temperature-related control member removal, such as unscrewing or twisting of the cover. The temperature-related control member or a coupling part actuated by means of the temperature-related control member can be moved substantially radially between a coupling position and a release position.
