7 Claims.

This invention relates to certain improvements "in cosmetic applicators such as lipsticks, and

aims generally to improve vthe construction and operation of lipsticks in general as well as those shown in the disclosures made in my following co-pending applications: Serial No. 699,025, filed September 24, 1946, entitled Lipstick (patented December 28, 1948, Patent No. 2,457,342) Serial No. 699,026, filed September 24, 1946, entitled Retractable Lipstick, patented August 21, 1951, Patent No. 2,565,346; Serial No. 751,035, filed May 28, 1947, entitled Non-Retractable Lipstick; Serial No. 755,607, led June 19,1947, entitled Manual Feeding Lipstick; Serial No. 756,598, filed June 24, 1947,` entitled Manual Feeding Retractable Lipstick and Serial No. 732,536, filed October 28, 1947, entitled Lipstick, patented March 20,r 1951, Patent No. 2,455,444.

It is the present custom in the manufacture of lipsticks to provide a lipstick container within which is situated a bar or solid cylinder of lipstick material which may be applied to the lips when the protective cap for the casing is removed. I have shown in my previously cited applications numerous improvements in the general construction of this type of lipstick and have disclosed a detachable type of cartridge with a unique lipstick applicatory surface, which may be used in conjunction with some lipstick casings now used, to provide 'protection for the lipstick material, as well as greater ease and accuracy in the proper application of the lipstick material to the lips. In this particular type of cartridge I have also provided means for feeding the lipstick material Within Vthe cartridge toward the applicatory surface of the working end as the lipstick material is consumed. As I have pointed out, such a cartridge may be detachable from the lipstick casing and ltherefore a particular shade of lipstick may be quite easily replacedby another cartridge containing a different shade. Such replacement procedure does, however, constitutea certain amount of inconvenience, especially soin view of the present day trend tcward using different sh'ades of lipstick for different lighting conditions throughout the day and evening.

It is a purpose of this invention to provide a general construction for a lipstick which will make available two shades of lipstick housed in the same common carrier with each shade of lipstick matter being" protected by a separate cover, and which may be made Servleble .by 1'6- moval of the'appropriate cap` (Cl. 20G-56) It is another object of this invention to describe a method of mechanical construction pertaining to a lipstick holder arranged tol dispense two shades of lipstick material from the opposite ends of a tube-like holder, the lipstick matter of each particular shade in turn being housed by a lipstick cartridge which is adapted for detachability from the dual carrier housing, and which while in place in said carrier rests in driving re'- lationship with respect to the same, allowing feeding of the lipstick material within the cartridge by relative rotation of a portion ofthe cartridge with respect to the casing.

It is further an object of this invention to dis'- close a means of frctionally retaining a lipstick protective cap on a lipstick housing which `is simple and economical of construction and obf` viates the possible viewing of worn surfaces attendant with such frictional retaining methods, said means being particularly useful in connection with the protective caps for foregoing dual lipstick holder casing and the cartridge type lipsticks of this and my other applications.

It is further an vobject of this invention to describe a method for economically achieving the aforesaid purposes by a construction utilizing in a number of its features sections of standard size tubing.

Thelipstick shown in Fig. 1 is a preferred ernvbodime'nt of my invention relating to the mounting. of. two lipstick cartridges: having,A different shadesiof lipstick in a commoncasing. The protective caps I and 2 are shown in place on the casing'3.- As bettereshownin Figs. 2v and aL-Fig, 3 being a longitudinal sectional. View of Fig.V 2, taken on: the line A--A of Fig. 2,. and looking in the direction of the arrowsthereofmy dual lipstick providesv detachable mountings for two lipstick cartridges 4 andAj 4a,v adapted to contain lipstick material 5 and 5c.- 'I'he particular form of cartridge shown is preferably of the. type described in my previously cited applications wherein. the cartridge 4 and 4a have working ends 6. and ha.,respectivelyr which. flat-frame and dene an improved applicatory surface for the lipstick. material. Since the two lipstick cartridges 4 and. 4aare identical in4 mechanical construction and the lipstick casing or holder providing mountings for l these two lipstick car.- tridges is symmetrical about. the center line B-B in Figs. 2, 3, 4 and 5, for clarity and ease of description I shalldescribe only the relationship of the cartridge elements to the left of the center lineB-B in the illustrations. of this embodiment. Asthe lipstick material 5 is consumed at the working applicatory surface 6 of the cartridge 4, the piston 1, which is threadedly' engaged on feed screw s may be advanced toward the working end 6` by relative rotation of the rotatable closure 9 and' the cartridge wall 4. I'he rotable closure 9 is disposed to rotate freely inthe counterbored and spun-over interior section IIl of the cartridge wall' 4, and tov this rotatable closure 9 is rigidly fastenedthe feed screw 8. A longitudinal spline II, mounted on' the inner wall ofthe car--v tridge 4, cooperates with a notch I2 in the periphery' of' thel piston 1 sol as to restrain the piston T from rotation with respect to' the cartridge Wall 4, but permit its axial movement as in feeding the lipstick material 5 towardV the working end 6 of the cartridge as it is driven by the feed screw 8.

The rotatable closure 9 from its bored out and transversely slotted aiirru-lar extension I3 having" av U-shaped clamping spring I4'1-lxed therein', is adapted to drivingly engage transverse driving pin I5 loosely mounted in diametrically opposite holes in the: wall of the'casing |61. This is most clearly seen in Figs. 4 and 5, which' are rep"- resentations' of the central portion of Figs. 2l and 3 respectively', but drawn to a larger scale. This particular method of cartridge closure driving engagement with the transverse pin I5 is described more exhaustively in my previously cited application, Serial No. 782,536, filed October 28, 1947, entitled Lipstick, wherein the advantages of mounting spring clamp I4 on the closure 9 in axial alignment with the slot Il in the periphery of the annular extension I3 of the closure 9 is more fully disclosed. However, when the lipstick cartridge 4 is in place in ,the casing I6 the diametricallyl disposed transverse slot Il, in the annular extension I3 of the cartridge closure 9. surrounds the transverse driving rod I5 while the restriction of the U-shaped spring clamp I4, mounted. in alignment with that slot, provides snap-acting engagement of the rod by the spring clamp and holds the cartridge 4 in driving relationship with respect to the driving rod. As it is shown, the driving rod I5 is mounted in large clearance holes I8 and I9 in the walls of the casing I6. These enlarged holes provide suilicient movement of the driving rod. I5 in its mounted position to considerably increase the permissible tolerances in. the overallconstruction of the lipstick and still allow reliable engagement of the pin by the cartridge slot I'I and spring clamp I4. It is therefore seen that in the mounted position of the cartridge 4 within. the casing I6, shown in Figs. 2, 3, 4 and 5, the rotation of the cartridge 4 with respect to the casing I6 through the driving action of the slot II and the driving pin I5 will cause rotation of the feed screw 8 with respect to the cartridge Wall 4, and hence effect axial movementV of the piston 1 Within the cartridge, causing feeding of the lip stick material toward ther working end 6 of the lipstick cartridge.

The holes I8 and I9 for mounting the driving pin I5 are shown to extend through the walls of the casing I5. Hence the cap hub 20 on which the protective cap I is held is made to cover these mounting holes. Thev cap hub 2U is held in place by solder or other suitable adhesive 2I, common to the casing I5 and the capI hub 20. A decorative ring 3 is in turnY fastened` to the outer periphery of the cap hub 25 by other suitable adhesive 22. This protective ring 3, as best shown in Fig. 5, tends to hide from view the wearing of surface 20 or 29a of the cap hub Ily when the protective caps are not in place.

As previously stated the dual lipstick casing as shownin Figs. 2, 3, 4 and 5 is symmetrical about the center line B--B, hence, all that has been said about the relation of elements of the left of said line BB may also be. said relative to the identical elements tol the right of center line B-B, which are designated by the suflix la For example the cartridge 4a to the right of the center line in Fig. 2 with its driving rotatable closure 9a and driving pin I5a is identically equivalent to the elements, 4, 9 and I5 to the left of the center line B-B.

In order that the protective caps I and 2 may be held by the circular cap hub 20 the protective caps I and 2 may be distorted in oircularity as shown in modified forms in Figs. 6, 7 and 8. In Fig. 6y the open or mounting end of the cap 23. shown in cross-section therein, has been distorted so that the opposite inner surfaces 23a.' and 23h are closer to the axis of the cap than the remote inner surfaces 23o` and 23d. The distortion of the mounting end of the cap 23' shown in Fig. '7 results in inner surfaces 23a', 23h and 23e being distorted in toward the axis of the cap preferably equidistant therefrom. Y In Fig. 8 distortion has been slightly modified toprovide four inner surfaces of bearing for the lipstick cap wherein sur'- faces 23a, 23h", 23e" and 23d are distorted toward the axis of the tube preferably equidistantr therefrom. However, whichever distortion is` used it is clear that when such distorted cap is placed on the circular cap hub 20 of my dual lipstick there must necessarily be a springing or yielding of the cap material to conform to the circularity of the cap hub 20. This yielding of the protective cap material provides a frictional spring action between the cap hub 20 and the inner surface of the protective cap suiiicient to detachably hold the protective cap in place on theV lipstick casing. As best shown in Fig. 3, the clearance 24 between the decorative ring 3 and the cap hub 20 is sufficient to prevent the'contact of decorative sheath 3 with the outer surface of the protective cap l or 2. This particular feature is desirable in that it eliminates any evi- 1 dence of wearing on the outside of the protective caps.

It is therefore seen that I have provided -a detachable mounting for two cartridges, which may contain different shades of lipstick material, within a common lipstick casing, said mounting providing driving action between the casing and the feeding mechanisms within the lipstick cartridges. I have further provided a simple and effective manner of mounting and holding the protective caps for said cartridges on the lipstick casing which is artistic in appearance and prevents viewing of worn surfaces of the lipstick casing or the protective cap when the protective cap is removed.

- -I-t is clearly evident that my improved method for mounting the lipstick protective cap on the casing may be applied to a single-element lipstick which may be of the general form shown in Figs. 9 to 13. As better shown in Figs. 10, 11, 12 and 13 the method employed to hold the protective cap 25 on the casing wall 21 is by means of cap hub 28 similar to the arrangement in my dual lipstick hereinbefore described. The cap hub 28 has a protective ring 26 which surrounds and is fastened to the outer surface of cap hub 28 by solder or other suitable means. As best shown in Fig. 12, the preferred method for assembling such a construction is to first insert the driving rod 30 in the holes 3l and 32 of the casing wall 21. This driving rod 30 cooperates with the closure 33 of the lipstick cartridge 34 by means of slot 35 and spring 36 mounted on said closure to provide driving activation of the feeding mechanism 31 Within the lipstick cartridge 34 whenever the sleeve of the lipstick cartridge 34 is rotated relative to the casing 21, as inembodiments heretofore described. After the driving pin 30 is mounted in the holes 3| and 32 of the casing wall 21 the cap hub 28 is then put in place to cover the mounting holes for the driving pin 30 and retain the pin therein, as well as to provide support for the protective cap 25, the cap hubs being fastened to the housing wall 21 by solder or other suitable adhesive 38. The circular end closure 39 for the lipstick casing end is then put in place and fastened to the exposed end surface of the casing wall 21 and the cap hub 28 by solder or other suitable adhesive 40. Finally the protective ring 26 is placed to surround the lower end of the lipstick casing as shown in Figs. 12 and 13, and is in turn brazed, soldered or otherwise fastened at 4l to the peripheral surface of the cap hub 28 in combination with the casing end closure 39. The cap 25 is distorted in a noncircular manner, such as in Figs. 6, 7 or 8, above,

so as to present frictional resistance in its placement on the cap hub 28, which frictional resistance serves to maintain the cap 25 in position on the, casing.
