Application July 2, 1951, Serial No. 234,719

8 Claims. (Cl. 206-56) The present invention relates to a cosmetic applicative holder particularly of the type designed to contain, project and retract a dispensable cosmetic in cake form to be applied by rubbing the cake against the face.

As distinguished from the lipstick type of cosmetic, which commonly is of relatively slim pencil-like shape, cosmetic cakes for application to the face require a greater area of rubbing surface for contact with the skin, and they are more convenient to use when their face marking surface area is of relatively long and narrow proportions because such shape offers a choice of breadth in the marking stroke. The problem of projecting and retracting a cake of cosmetic whose cross-sectional profile is of such size and proportions, as distinguished from the usually slender, cylindrical and crayon-like lipstick, calls for a new and different kind of operating mechanism for moving the cake carrier successfully between projected and retracted positions.

It is an object of the present improvements to provide an applicative holder for a cosmetic cake of relatively long and relatively narrow cross-sectional shape which shall insure a smooth action of the cake carrier in its sliding movement even when resisted by daubings of the cosmetic that may become lodged between the relatively movable parts of the holder mechanism.

Another object is to decentralize the cake carrier motivating mechanism in order to take advantage of the noncircular and unequal cross-sectional proportions of the carrier for housing in rather widely separated relation plural motivating screws which then may act simultaneously on the cake carrier at points well separated laterally to impel it forcefully in sliding direction while serving also to constrain it against disalignment with its direction of sliding movement that might cause it to cock or jam in the guide well of its casing.

Another object is to enable the shape of the outer casing to follow closely the shape of the cosmetic cake so that the bulk and over all dimensions of the entire holder may be kept to a minimum in comparison with the size of the cosmetic cake held and dispensed thereby.

A further object is to afford combined functions for the roughened surface of a wheel handle so that it may serve both as a motion transmitting gear and as a rotary actuator to be grasped and turned by the fingers of the users hand.

A further object is to arrange such wheel handle coaxially with the line of reciprocative movement of the carrier of the applicative cosmetic cake.

A further object is to provide an assembly comprising plural impelling screws and a train of gears operatively interconnecting them so that all these working parts may be removed from the casing by merely displacing a common thrust affording element that retains them against axial movement when in place.

These and related objects of the improvements will ap pear in greater particular from the following description of a, successful embodiment of the invention having ref-.v erence to the appended sheet of drawings wherein:

Like reference numerals refer to respectively like parts of the structure throughout the drawings.

The casing body 12 of my improved applicative holder has a hollow fully encompassed by said body which provides a guide well 13 extending in an axial direction and open at one axial end to permit. the projection and retraction therethrough of a cake of cosmetic marking substance 14. This cosmetic cake is lodged in a slidable carrier cup 15 which is preferably ovate or of elongate shape along a major axis in transverse profile, as is the cosmetic cake. Thus the top or applicative surface of the cake is of relatively large area and presents a shape which gives a choice of width of marking stroke depending upon the direction and angle at which the cake is applied and wiped against the users face.

Carrier cup 15 is equipped with two follower lugs 16 which project laterally therefrom. Each of these lugs tracks axially in impellable engagement with only the nearest sides of equally pitched helically winding threads of impelling screws 17 when the latter turn in unison. Each of these screws is in outboard relation to and substantially isolated from the guide well 13. The threads of screws 17 comprise helical tracks so engaged by follower lugs 16, respectively, that the lugs are kept on a common level to prevent cocking or jamming of cup 15 in well 13. To help insure this the impelling screws are spaced laterally apart as far as is permitted by the transverse dimensions of the casing.

Each impelling screw 17 substantially fills the girth of or rotatably fits, and is axially retained within, a full length bearing hole or transmission chamber 18 in casing body 12. Each of these bearing holes communicates laterally withguide well 13 through narrow vertical slots 19 in a partition intervening between the guide well and each of screws 17. The partitions comprise walls spanning and dividing the hollow of the casing body into the guide well 13 and the transmission chambers 18. Follower lugs 16 are free to slide up and down in slot 19 but are restrained thereby against turning movement about the central axis of the casing. Thus the carrier cup 15 is kept from turning about its vertical axis and does not depend for this constraint upon its ovate profile nor the fit thereof within the guide well 13, wherefore the carrier and well might, if preferred, be round instead of ovate.

On the bottom end of each impelling screw 17 there are fixed pinion teeth 22 which are located rotatably in mesh with corresponding gear teeth 23 on the periphery of a rotary actuator'which as here shown is in the nature of a wheel handle 24 having a multiple ridged periphery afiording gear teeth 23. The small pitch of gear teeth 23 and the absence of .sharp edges thereon adapt the square? threads or helically; winding finsz V lieved' unnecessary to mention or illustrate- -the= many 'other'lvarieties oflconstruction by which a worn'i' like turned by the fingers of a users hand applied to di-' ametrically opposite segmental portions of the handle which are exposed for manipulationoutside the confines of the base1portion of casing'body 12asi'showrr in Figs. 1; 2; 4; 5 and 6; Other portions' ofithe wheel-handle are concealed Within the confines of easing body 12; the latter being circularlyirecessed at 25. to accommodate the central concealed portions ofthe wheel handler,
