Abstract: A battery cell includes: a housing having a prismatic shape with a venting side and a terminal side that is different from the venting side; an electrode assembly inside the housing; a terminal arranged on the terminal side; and a venting valve on the venting side. The venting valve is configured to switch between a closed state and an open state. The venting valve, when in the open state, forms a vent opening in the venting side of the housing, and the vent opening is at least 15% of the total area of the venting side.

Abstract: A closure device for drinking from a liquid container (2) is sealingly mounted with a bottom part (3) of a main body thereof extending into an opening of the container. A top part (4) has a circular-arc portion with a groove (6) therein. Liquid-emitting and air-admitting bore holes (10, 11) are positioned in a base of the groove. A pivotally movable cap (14) is mounted on the top part covering the groove. When the cap is pivoted, it causes a flexible hose (12) mounted in the liquid-emitting bore hole to bend and thereby closes it. At the same time, the bent hose closes the air-admitting opening.

Abstract: Bottle or similar container, especially for readily combustible liquids, with a screw-on closure. There is an insert in the neck of the container with two parallel openings through it. One is a liquid outlet and the other an air inlet. The air inlet is extended by a tubular projection that is oriented inward and liquid outlet a tubular projection that is oriented outward. Each of the openings can be closed off from inside the container with a separate plug, one plug being rigidly attached to the other. The plug that is associated with the air inlet is extended by a bolt that passes through it. The bolt is loaded with a spring in such a way that the plugs automatically close off both openings. A stopper is screwed into the neck of the container and has an external annular shoulder that rests on the upper edge of the neck.
