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.
