Abstract
The present invention relates to a relative translational driving of a piston-forming part into a body, as well as the application of the device to an applicator apparatus. The device includes blades (5) of which the cutting edge is inclined with respect to the longitudinal axis X-X' of the piston-forming part (4) or of the body (2), the blades being integral with the external wall (4a) of the piston-forming part (4) so as to bite on the internal wall (2a) of the body (2) so that the rotation of the piston-forming part (4) with respect to the body (2), or vice versa, causes the displacement of the part into the body (2). This device applies for example to the fabrication of an applicator used to apply a viscous fluid such as nail varnish, or a solid gel such as a deodorant gel.
