A bead (6) of an elastic storage bag (7), partly inserted into the inner area of the protective flask (1), is clamped between the circular bed (5) and the lid (8). A working bag (11) is fastened to the pressure valve (10), the bag being partly inserted into the inner area (13) of the elastic storage bag (7), into which a charge and discharge valve (14) mouths, said charge and discharge valve (14) being built in into the lid (8) and provided with a spraying discharge nozzle (15) outside of the lid (8).
