Disclosed is a container for keeping fermented food, including a body configured to contain the fermented food therein, a cover configured to close the body, and a sealing sheet configured to maintain airtightness between the body and the cover. The cover includes a plurality of gas flow channels which extend from a center of a bottom surface to an inner peripheral surface, and a plurality of gas discharge channels which extend from an upper end of the inner peripheral surface to a lower end. In addition, the sealing sheet has a through-hole to allow an interior and an exterior of the body to communicate with each other.

To solve the above problem, a venting device inserted into a sealing part of a pouch of a secondary battery according to the present invention includes: a housing inserted between confronting surfaces of the sealing part and sealed together with the sealing part; an element made of a metal and disposed in the housing and through which a passage is defined providing gas communication between an inside and an outside of the pouch; and a ball disposed at an outlet-side of the passage, the ball configured to open and close the passage, wherein, in the element, an edge of an inner circumference of a surface of the outlet-side of the passage is chamfered or filleted so as to face the ball, and the element includes: a surface treatment layer formed on the chamfered or filleted surface; and a layer made of a polymer and fused to the surface treatment layer.

A hydraulic device for a rail vehicle includes a fluid container, a motor with a pump, a control plate, a control region, a ventilation and purging unit for ventilating and purging the fluid container, wherein the ventilation and purging unit has a valve unit integrated into a wall of a housing of the fluid container, and a channel labyrinth connected to the valve unit.

A bottle cap includes a vacuum unit, a pressure relief unit and a drinking water pipe unit. After the bottle cap is combined with a bottle, the vacuum unit can vacuum the interior of the bottle to preserve food or drink inside the bottle, and the pressure relief unit may be operated to release the air pressure in the bottle in order to open the bottle cap, or open a flip cover of the drinking water pipe unit to drink the fruit juice or water from the bottle. The bottle cap has the effects of preserving the food or drink in the bottom and facilitating drinking.

A dispensing closure for dispensing liquid, comprising an outer nozzle component (6) defining a nozzle opening (66) and a valve assembly (7) disposed in the closure upstream of the nozzle opening, the valve assembly comprising an outer valve element (3) and a generally rigid intermediate valve seat element (4) disposed inwardly of the outer valve element, the outer valve element comprising an outer valve flap (38) and the intermediate valve element (4) defining an outflow opening (451) bordered by an outer seat region (411, 471), the outer valve flap (38) being movable between a closed position, in which it overlaps the outer seat region of the intermediate valve element to close the outflow opening (451) against inflow therethrough, and an open position, in which it is deflected away from the outer seat region (411, 471) to open the outflow opening for outflow.

An assembly of a closure with a container, for sealing of the container, comprises the container having an inner container surface defining a cavity opening to ambient through an opening, the closure comprising an upper portion and a lower portion, the lower portion having a lower lateral surface, the lower portion being adapted to be inserted into the opening of the container and two grooves provided on the lower lateral surface and adapted to receive two respective sealing members, the two grooves being separated by a predetermined distance, the two sealing members provided in the two respective grooves, the two sealing members being adapted to provide sealing between the lower lateral surface and the inner container surface, wherein the lower lateral surface, the inner container surface and the two auxiliary sealing members together define an annular space and a barrier sealant in the annular space.

A package that may be employed to store a tobacco-containing material is provided. The package may include a container and a valve assembly. The container may include a body portion and a cover configured to engage the body portion. The body portion may define an internal space therein. The valve assembly may be configured to affect an atmosphere within the internal space of the container. For example, the valve assembly may remain closed except when releasing pressure from the internal space. Thereby, by way of further example, the valve assembly may vent the container so as to avoid damage thereto, while reducing moisture loss from the tobacco-containing material stored in the internal space.

A cap assembly for a container and a method of assembly. The cap assembly includes a housing couplable to a container opening, the housing defining a housing opening communicating with the container opening; a cover operable to close the housing opening; and a retainer mechanism operable to releasably connect the cover to the housing, the retainer mechanism including a non-fusible member selectively contacting the cover and the housing, and a fusible member operable to hold the non-fusible member in contact with the cover and the housing in a retaining condition, the fusible member deforming at or above a threshold of the condition to allow the non-fusible member to move out of contact with one of the cover and the housing, in a release condition, to open the container opening to atmosphere.

A system is provided for venting a container used to supply a liquid to a spray coating device. The system may include a container cover having a buffer chamber, a liquid conduit configured to extend into a liquid container, a first vent conduit that extends into the buffer chamber, and a second vent conduit that extends from the buffer chamber to the liquid container.

A bottle has a storage compartment to store an item. The bottle includes a top opening, a bag inside the bottle defining the storage compartment, a bottom opening formed by an opening of the bag, and a bottom cap that includes at least one hole. The bottom cap is removably connected over the bottom opening to provide access to the storage compartment.
