ABSTRACT:
Sealing and safety device made from flexible elastomer material, for filling a hollow body with a liquid using a delivery nozzle, comprising an annular seal for surrounding the nozzle and preventing the exit of gases from the hollow body and also a valve capable of opening, in the event of excess overpressure in the hollow body, only towards the external atmosphere so as to create a passage allowing the escape of liquid and/or of gas.
