ABSTRACT:
An applicator device comprises a front portion and a gripping portion which are rotatable relative to each other to displace a stick of spreadable material axially by means of a screwthreaded spindle. At its rear part which is towards the gripping portion the front portion has a coupling part for non-rotatable connection to a nut member disposed in the gripping portion. The nut member has radially elastically resilient claw portions which can be brought into engagement with the screwthread of the screwthreaded spindle by the coupling part of the front portion bearing against the claws. The claw portions are disengaged from the screwthreaded spindle when the front portion is removed from the gripping portion. Disposed in the gripping portion between a part thereof and the screwthreaded spindle is a spring which, after being mechanically stressed in the forward feed movement of the screwthread spindle, moves the screwthreaded spindle back into its starting position in the gripping portion when the front portion is removed from the gripping portion.
