<p>Aerosol-type packaging container, refillable with compressed gas, including an outer casing fitted with a filling nozzle provided at its outer end with means for connecting it to a source of compressed gas and internally connected to a filling tube, the free end of which emerges into the casing of the container above the level of the liquid contained in the latter. It comprises, mounted at the free end of the filling tube (7), a sealing device (9) arranged in the form of a housing (10, 14) which includes a chamber (19) delimited between a lower wall (11) and an upper wall (15), the said chamber communicating with the internal volume of the casing via at least one orifice (16) made in the upper wall (15), and with the filling tube (7) via orifices (12) made in the lower wall (11) on the outside of a central part of the latter, and, inside the said chamber (19), an elastic membrane (20) immobilised in its central part against the central part of the said lower wall (11). <IMAGE></p> |
