ABSTRACT:
Applicator device for cosmetic preparations, having a closed, substantially cylindrical casing in which a piston dividing the casing into two variable-size chambers sealed from one another is displaceably disposed, the one variable-size chamber being fillable with the cosmetic preparation and being combined with a removable applicator provided with a passage for the preparation, by means of which the cosmetic preparation can be applied to the body part being treated, in quantities controllable by means of a self-closing valve. The variable-size chamber opposite the preparation reservoir is provided with a connection for bringing in a compressed gas which seeks to displace the piston to reduce the preparation reservoir, and in the passage connecting the preparation reservoir chamber to the applicator there is disposed the self-closing valve preventing escape of the preparation when the applicator is removed. In the cylindrical casing there is a plunger extending into the preparation reservoir chamber and engaging directly or indirectly the valve body of the self-closing valve, which passes through the piston in a displaceable and sealed manner and is coupled in its end area remote from the self-closing valve with a venting valve for the variable-size compressed gas chamber lying opposite the preparation reservoir chamber such that the maximum opening movement transmitted by the valve body to the plunger upon the opening of the self-closing valve opens the venting valve.
