Abstract
Abstract An applicator is affixed to the forward end of an elongate driver or shaft extending into a barrel structure, and having a rear head meshing with internal threads in a female member of the barrel structure, the driver being splined to a forward sleeve adapted to surround the applicator and being swivelly connected to the female member. A removable cap containing a cosmetic mass has its rear portion surrounding the sleeve and rotatable on the barrel structure, the cap frictionally engaging the external portion of the sleeve to provide a slippable clutch therewith capable of transmitting a predetermined torque before slipping, whereby relative rotation in one direction between the barrel structure, on the one hand, and the cap, sleeve and driver, on the other hand, produces forward feeding of the applicator toward and against the cosmetic mass, continued relative rotation and application of torque causing the clutch to slip, while effecting relative rotary movement between the applicator and cosmetic mass to coat the applicator with a portion of the mass. Removal of the cap exposes the coated applicator for use.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
200 words
In an applicator: a barrel structure; a cap rotatably and removably mounted with respect to said barrel structure; marking means; companion means in and rotatable with said cap for operation upon said marking means when engaged therewith; a screw and nut device comprising a female member forming part of said barrel structure and having an internal thread, a male member in said female member meshing with said thread and connected to said marking means; a rotation transmitting member swivelly connected to said barrel structure and projecting forwardly beyond the forward end of said barrel structure; means providing a slidable spline connection between said rotation transmitting member and male member to couple said members together for joint rotation while permitting axial movement of said male member along said rotation transmitting member; and means providing a torque responsive friction clutch between said cap and rotation transmitting member when said cap is mounted on said rotation transmitting member, said clutch slipping at a predetermined torque imposed thereon to limit the axial force that can be imposed upon said marking means when engaged with said companion means, said friction clutch being separate from the threaded engagement of said feMale member with said male member.
Claim 2
Dependent Claim
200 words
In an applicator: a barrel structure; a cap rotatably and removably mounted with respect to said barrel structure; marking means; companion means in and rotatable with said cap for operation upon said marking means when engaged therewith; a screw and nut device comprising a female member forming part of said barrel structure and having an internal thread, a male member in said female member meshing with said thread and connected to said marking means; a rotation transmitting member swivelly connected to said barrel structure and projecting forwardly beyond the forward end of said barrel structure; means providing a slidable spline connection between said rotation transmitting member and male member to couple said members together for joint rotation while permitting axial movement of said male member along said rotation transmitting member; and means providing a torque responsive friction clutch between said cap and rotation transmitting member when said cap is mounted on said rotation transmitting member, said clutch slipping at a predetermined torque imposed thereon to limit the axial force that can be imposed upon said marking means when engaged with said companion means, said friction clutch being separate from the threaded engagement of said feMale member with said male member.
