Abstract: An aerosol system for dispensing a hair lacquer having a flammability classification less than or equal to 4 according to the Roth apparatus comprises, in combination, an aerosol recipient provided with a value equipped with a dispenser wherein the valve and dispenser have orifices such that the initial outflow of the hair lacquer is between 0.5 and 0.7 g/s. The aerosol recipient contains a hair lacquer composition consisting of 12 to 25% by weight of water, 10 to 26% by weight of an alcoholic phase selected from the group consisting of ethanol, isopropanol and mixtures thereof, and 49 to 78% by weight of dimethyl ether, the alcoholic phase containing from 3 to 5% by weight, compared to the total weight of the composition, of a synthetic film-forming resin.

Abstract: A packaging container of the aerosol type, which can be recharged with compressed gas, comprising an outer casing capable of being connected with a filling adaptor provided at its outer end with means for connection to a compressed gas source and connected on the inside to a filling tube whose free end opens inside 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 case (10, 14) comprising a chamber (19) delimited between a lower wall (11) and an upper wall (15), the chamber communicating with the internal volume of the casing through at least one orifice (16) made in the upper wall (15), and with the filling tube (7) by orifices (12) made in the lower wall (11) outside a central part of the latter, and, inside the chamber (19), an elastic diaphragm (20) immobilized in its central part against the central part of the lower wall (11).
