An external shell as herein a support for a cosmetic applicator element slidable between a retracted position and an extended position for use of the element. The support is connected to a first rack which extends parallel with the axis of the shell but which is offset in relation to this axis. The first rack meshes with a pinion free for rotation about a pin fixed to the external shell and extending substantially perpedicular to the axis of the shell. The pinion meshes with a second rack parallel to the first but diametrically opposed relative thereto in relation thereto the pin. The second rack is solid with a sleeve which is slidable in the shell and in which the support is slidable. The cosmetic element is, in its retracted position, entirely accommodated within the sleeve and in its position for use, projects at least partially out from the sleeve.
A case for a cosmetic applicator element comprising an external shell having a longitudinal axis and a bottom, a support mounted within said shell, said support being adapted to carry the applicator element and being displaceable in translation in said shell between a retracted position and an extended position ready for use, a first rack connected to said support and extending parallel to the axis of the shell but offset in relation to said axis, a pin fixed in relation to the external shell and substantially perpendicular to the axis of said shell, a pinion freely rotatable about said pin, the said first rack meshing with said pinion, a second rack meeting with said pinion to control its rotation, said second rack being disposed parallel to the first rack and being diametrically opposed to the latter in relation to the pin and pinion, a sleeve slidable within the external shell and integral with said second rack, said sleeve having an internal wall and an inner portion relative to said shell, said second rack being located on said internal wall and on said inner portion of said sleeve, said sleeve being coaxial with said external shell and being disposed within a portion of said external shell through which said support is displaceable, said support being disposed coaxially and slidably within said sleeve to an extent limited by said second rack, the support being slidable within the external shell and integral with said second rack, the said support being thus displaceable towards the extended position or the retracted position of the applicator element when said sleeve is displaced respectively towards the inside or the outside of the external shell, the applicator element being, in its retracted position, entirely accommodated within the sleeve and in its extended position, projecting at least partly out from said sleeve, said support having a base which is formed integrally with said first rack, said first rack extending parallel to the axis of said support towards the bottom of said external shell.
