Referring to the drawings, the base |0 includes a lower housing portion I I and an upwardly extending noncircular tube or casing |2. A cover I3 is provided with a noncircular bore 4 adapted to receive the casing |2 in telescopic relation. The bore I4 is preferably longer than the casing l2 in order to provide a clearance space I5 between the upper end I5 of the casing I2 and the end wall I1 within the cover I3. When the cover is in position on the casing l2 the lower end |8 of the cover is adapted to rest on the shoulder I9 at the junction of the casing |2 and housing portion of the base I0. A paste or cream ller element 20 is adapted to t in sliding relation within the noncircular bore 2| in the casing I2, and its lower end 22 is reduced in size to t within the carrier 23. The filler element 20 preferably rits closely within the bore 2| and may have little or no clearance with respect thereto.

The carrier 23 is provided with a continuous upwardly extending wall 24 adapted to encircle the lower end 22 of the iiller element 20, and a pair of tabs 25 cut from the Wall 24 may be delected inwardly to prevent disassembly of the filler element 2u from the carrier 23. The bottom wall 26 of the carrier 23 is provided with a central angularly shaped aperture 21 adapted to receive the upward tubular knob 28 provided on the carrier extension or tubular post 23. The post 29 is connected to the carrier 23 by inserting the knob 28 through the aperture 21 and then deforming it as shown in Figure 5 at 28a, thereby forming a rigid connection between the carrier 23 and the postl 29. These parts then function as a single integral unit. The carrier 23 is adapted to slide vertically within the bore 2| of the casing I2, but relative rotary motion is prevented because the parts are noncircularin cross section.

The housing portion of the base |0 is provided with a central cylindrical bore 30 and an axially aligned cylindrical counterbore 3|. The counterbore 3| is of greater diameter than the width of the base I0, and accordingly the counterbore 3| is not continuous but is interrupted by lateral windows 32 as shown in Figures 1, 4 and 6. The carrier extension or tubular post 23 extends downwardly through the bore 30 and into the counterbore 3| when the carrier 23 is in its retracted position.

Means are provided for advancing and retracting the carrier 23 within the bore 2| of the casing I2, and as shown in the drawings this means includes a plurality of concentric sleeve assemblies 33 and 34 encircling the carrier extension 29. The inner sleeve assembly 33 comprises a cam sleeve 35 split longitudinally at 36 and provided with a helical groove 31. The assembly 33 .also

includes the shell 38 which is tubular in form and adapted to enclose the cam sleeve 35. A lateral projection or cam follower 39 formed on the tubular post or carrier extension 29 extends outwardly into the helical cam groove 31 provided on the split sleeve 35. A boss 40 extending outwardly from the split sleeve 35 vis adapted to be received within the recess 4| provided in the wall of the tubular enclosing shell 38. A slot 42 may be provided which extends from the upper end of the shell 39 to the recess 4| in order to facilitate assembly of the split sleeve 35 within the enclosing shell 38. When thus assembled the split sleeve 35 and enclosing shell 38 function as an integral sleeve member.

In like fashion the outer sleeve assembly 34 comprises a cam sleeve 43 vertically split as shown at 44 and provided with a helical cam groove 45. A lateral projection or cam follower 6| provided on the enclosing shell 33 extends into the helical groove 45. An enclosing shell 46 Whichis-tubular in form is adapted to encircle the split-sleeve 43 and to be connected therewith by means of the recess 41 which receives the boss 48 on the split sleeve 43. Assembly of the split sleeve -43-into the enclosing shell 46 is facilitated by means ofthe slot 49 extending from the upper endiof the shell 46 tothe recess 41. A laterally extending flange 50 on the upper end of the shell 46 lsadapted to rest on the shelf 5| provided at the lower end of the bore 2| of the casing |2. An actuator knob 52 is provided with a central opening 53 adapted to yreceive the shell 46 tightly therein. Friction-lips 54 may be provided on the shell 46-and extend outwardly therefrom to' increase the frictional grip between the bore 53 and shell 46. When thus assembled the actuator knob 52, shell 46 and split cam sleeve 43 function as a single integral sleeve member.

"The knob 52 is rotatable within the counterbore 3|, andportions of its fluted periphery 55 are accessible through the lateral windows 32 in the housing portion of the base |0. The upper surface'- 56 of the knob 52 rests against the downwardly 'facing` abutment 51 on the housing portion of the base I6. Downward movement of the knob 52 is prevented by the frictional contact with the enclosing shell 46, and upward movement of the knob 52 is prevented by contact with the-abutment 51. The housing portion which partially encloses the knob 52 prevents lateral forces applied to the knob from imposing objectionablel bending stresses on the cylindrical shell 46. The knob is prevented from moving laterally by its contact with the recess or counterbore 3|. Each of the split cam sleeves 35 and 43 is-preferably formed from a Aflat sheet as indicated-at 58. The Ysheet'may be formed of any suitable material such as, for example, metal and may be punched to form the slot 59 and dimple 60. It will be observed that the slot 59 is closed at'both ends. The sheet may be then rolled into a-cylinder to form rthe cam sleeve 35 or 43, the slot 59 becoming a helical cam groove and the dimpler fforming an externally-protruding boss. In oper-ation the mechanism for advancing and retracting the carrier 23 within the noncircular bore2-| operates as follows: The actuator knob 52 maybe rotated by means of the users fingers which may Contact the fluted periphery 55 through the ports or windows 32. Rotation of the actuator knob 52 causes rotation of the outer sleeve assembly 34, the enclosing shell 46 and split earn sleeve 43 rotating with the knob 52 as a unit. Rotation of the split cam. sleeve Y43 effects vertical travel of the tubular post 29 and carrier 23. Since the carrier 23 slidably engages the noncircular bore 2| rotation of the carrier 23 and extension 29 cannot occur, and accordingly, rotation of the knob 52 causes one of the cam followers 39 or 6|, or both, to travel in their respective cam grooves 31 and 45.

VFriction characteristics of the cam followers 6| and 39 and cam grooves 45 and 31 determine which of the sleeve assemblies 34 or 33 rotate or whether both rotate simultaneously, but in any event the post 29 and carrier 23 move upwardly within the bore 2|.` vAssuming that the inner sleeve assembly 33 does not rotate with the initial rotation of the knob 52, the cam follower 6| is caused to move upwardly along the helical slot y45 in the camv sleeve 43 as the latter rotates with the knob k52. When the cam follower 6| reaches the end of the helical groove 45 the shell 38 and split cam sleeve 35 are caused to rotate. The cam follower 39 on the tubular post 29 then rides upwardly in the helical cam groove 31 in the split cam sleeve 35. The upper limit of movement is reached when the cam followers 6| and 39 arrive at the upper ends of their respective helical cam grooves.

The carrier 23 is retracted downwardly within the noncircular bore 2| upon rotation of the actuator knob 52 in the opposite direction. In such event the cam followers 39 and 6| travel downwardly withinl their respective cam grooves until the inner and outer sleeve assemblies 33 and 34 are fully retracted as shown in Figure 5. Since the helical cam grooves 31and 45 are usually enclosed by an encircling shell 38 and 46 respectively, the cam followers 6| and 39 are separated by solid Walls and thereby any possible interference is avoided. The provision of the lips 25 on the carrier 23 serves to effect retraction of the ller element 20 within the noncircular bore 2| and avoids the possibility of relative sliding movement between the carrier 23 and filler 29.

It is contemplated that the filler element 20 may comprise a cosmetic cream or paste suitable for application to the skin of the user to serve as a foundation for other cosmetic preparations such as powder or rouge. The user may dip her fingers into the cosmetic paste and then apply it to several locations on the skin, blending it out in the usual fashion. The oval or generally elliptical shape of the noncircular bore 2| facilitates easy access of the fingers to the cosmetic paste 20. Such paste may be of relatively low melting point and may therefore be tacky or sticky. The noncircular bore 2| and carrier 23 serve to prevent rotation of the ller element 2i! within the casing I2 and hence no clearance is necessary between the filler element 29 and the bore 2|. Accordingly, a more stable support is provided for the filler element 29 than if such clearance were necessary in order to accommodate the relative rotary movement. This additional supporting effect is particularly useful for sticky or tacky pastes and creams.

It will be noted that the construction of the casing I2 and carrier 231s free from grooves, pins",- slots, etc., and that leakage or plastic iiow of 4cosmetic cream into the advancing mechanism is effectively prevented. It will be observed also that the total travel of the carrier 23 is substantially greater than the overall length of the nesting sleeves constituting the advancing mechyanism. Thus when the carrier 23 is in its fully extended position the upper edge thereof assumes the position indicated by the dashed lineA 62 `in Figure 5. It is recognized that a greater number of interfltting sleeve assemblies may be employed if desired in order to increase the total travel of the carrier 23 or to decrease the overall length of the sleeve assemblies. Thus while only two sleeve assemblies 33 and 34 are shown in the drawing, it is possible to use three or four such assemblies if desired. The full 'amount of travel made available by Iany one particular cam sleeve is accomplished by turning the actuator knob through an angular travel somewhat less than a full revolution. By employing two, three, four or more cam sleeves the knob m-ay be rotated through any desired number of revolutions to correspond with the desired travel of the carrier.

While any suitable or desirable materials for the cosmetic holder and advancing mechanism may be employed, I have found that plastic materials such as, for example, polystyrene are well suited for the base l0, cover I3 and knob 52, whereas the carrier 23, tubular post 29 and sleeve assemblies 33 and 34 are preferably formed cf thin gage metal such as, for example, steel.
