Abstract:
A device by which a supply container containing a medium subjected to positive pressure is connected in a sealed manner to a consumer element, comprising:a consumer-element body which has a cutout with an internal thread; a connection element for connecting to the supply container having a re-sealable valve, an annular sealing surface on an end side, an external thread for being screwed into the internal thread, an opening element connected to the consumer-element body and intended for opening the valve automatically when the connection element is screwed into the consumer-element body, and an annular sealing element which, on the one hand, interacts with sealing interaction with a base of the cutout and on which bottom annular sealing surface the sealing surface comes into abutment when the connection element is screwed in; and wherein the bottom annular sealing surface of the sealing element is arranged in relation to the opening element such that when the connection element is screwed in it interacts with sealing interaction with the sealing surface before the valve is opened and when the connection element is screwed out, the valve is closed before the sealing interaction is eliminated, and the sealing element is designed in order to accommodate at least the displacement for the sealing interaction with the connection element and the opening displacement of the valve.
