(CE-2U6- 56) This invention relates td a lipstickholder of the type which includes concentric inner outer cylindrical Shell's, the inner shell presenting a longitudinal bore to receive a carrier for the lipstick cartridge, and the carrier being" provided with opposed laterally extending pins to cooperate with two l'ongitudihalislotsin the inner shelland' two helical uideweys in the outer'shell. The arrangement. is. such that as the inner shell, for. instance,v is rotated relatively to the outer shell in one direction, the carrier will he moved longitudinally along thebore: toproject the lipstick cartridge, whenvits' use is desired; whereas, when the parts are relativelyrotated in the op:-

posited-irection; the carrier willbe moved in; the reverse direction to retract the -l '1-pstick cartridge into the bore, as when it is not to beused It is also customary to provide such a lipstick .conitaliner with-a cover-or cap to;preventaccess to: the

lipstick of contaminating foreign matter, as well aas-='to-prevent the lipstick itself: trom coming into contact with and. soiling other" articles.

I-t lirequently happens that; in lipstick holders of this type, the carrier for the lipstick cartridge will wobble when projectedfromand into the Thziswehhlinga mayresultin the ;lipstick being pressed? against the adjacent wall :o'f the inner shell, smearing thewlatter, or it may result instainingzthefingers'ot theuser, or both these undesirable results may happen. A furither and even more seriousiresul t is that the lipstick; is carefully made to give the best service inuse, may 'be deformed and thus "rendered less serviceable,-=iinot entirely unfit, for Indeed,- in many instances the lipstick holders are rejected because of such faulty operations;

With the foregoing defectsinview, a; .prihie object of the invention i's to produ'ce a lipstick holder whose rotatable parts will be so con!- structed and arranged. that'the lipstick or car- .It'ridge carrier can 'be. projected". into and out. of its housingv shell easily andquickly and without any wobblingor swaying or other deviation from 1 a true, course.-

The cartridge: carrier 3 is open at the tohto receive the lipstick cartridge 4* which, when in sorted in thecarrierv is; suitably heldagainst tuming, as by triangular prongs I 0 rising from a base; plate fl I-. It is 'to b'e" understood that 'the ,lipstickcartridg-e-Jis relatively soffi andi must be pushed down into thecarrier when the device isuloaded fto v beconie impaled on the prongs 4 0. Thescarrien is also-formed, as-u'sua'l, a pair zof; diametrically opposcd. pins 123, M, integral with and projecting laterally from its outer cylindrical :surface; and: which pinsa're located :nearvthe: bottom ofiithercarrier;

"Thee-inner: shel-li 1' lssdivided anoveits base: \5 .intortwowsections, seml cylindricali in form ex?- ceptithatrtheir: edges slare out awayto present'za pair of diametricallyr opposed verticall slots 15; f6, ith mughl whihhlthe pin-s t3, :Hi respectively; =exvtend-.- Thlese rpins lp'roject beyond the slots and 'intor'a :pair of helica'ligifooves' lz'lr, it, presented by the inner'walii of the dutensheilwa The grooves .and the same groove. the upper and lower pins and I4 will travel metrically opposed points, and terminate slightly below the top thereof.

According to the foregoing arrangement, when the carrier 3 is in its lowermost position, as determined by the banking of the pins I3, i l, against the base 5 of the inner shell (which, it may be noted, is recessed as at I9 to accommodate that portion of the carrier 3 below the pins It, I4) the lipstick, cartridge will be located entirely within the confines of the bore 2. However, assuming that the cap I has been removed, when the inner shell I and the outer shell 6 are relatively rotated, as by holding the outer shell and rotating the base portion of the inner shell in one direction, the carrier 3, by virtue of the engagement of its pins I3, I4, in the helical grooves ,II, I8, respectively, of the outer shell, and the vertical slots I5, It, of the inner shell, will be moved upwardly to project the lipstick beyond the bore 2 so that access to it may be had; and, conversely, when the inner and outer shells are relatively rotated in the opposite direction, the carrier 3 will be moved downwardly to retract the lipstick cartridge within the confines of the bore.

As has been stated, in constructions of the foregoing character, it frequently happens that there is a wobbly or unsteady movement of the carrier 3 in its movements to and fro in the inner shell I, with the adverse results heretofore described. In accordance with a prime feature of the invention, therefore, means are provided to overcome or avoid such wobbly or unsteady movements of the carrier and for insuring at all times that the lipstick carrier in its movements shall pursue a true and even course. To furnish such means preferably and as shown, see Fig. 5, the

carrier 3 is provided with two additional pins 2| integral with and projecting laterally from its outer cylindrical surface. These additional pins are arranged on opposite sides of the carrier and in vertical alignment with the pin-s I3, I4,

respectively, and, projecting through the slots I5, I6, extend into the grooves I'I, I8, all in like manner as the pins I3 and I4. It will be observed that the vertical slots I5 and I6 are diametrically opposed in position and that thepins I3 and I l and 20 and 2|, while travelling along the helical grooves II, I8, must proceed vertically upward in the said slots I5 and IIS. It 'is also pointed out that the vertical distance between .the axial plane of the pins 20 and 2I and the axial plane of the pins I3 and It is preferably equal to the pitch of the convolutions of the helical grooves I'I, I8, although if desired 'said distance could be made equal to one-half of said pitch. In the first instance, the upper and lower pins 20 and I3 will travel in one groove I! or I8, as the case may be, while the upper and lower pins 2! and I4 will travel in the other groove; in other words, the two pins located on the same side of the carrier will travel in one In the second instance,

in one groove II or I8, as the case may be, while the upper and lower pins 2| and I3 will travel in the other groove; in other words, the two pins located on the same side of the carrier will travel in different grooves. Thus equipped, the carrier 3 in its up and down movements within the inner shell I will at all times maintain its stability or keep on a true course.

The inner shell I is formed at the top with an external annular boss 22 which fits into a complementary recess 28 formed in the inner face of the outer shell 6, the boss 22 and the .recess 23 presenting interengaging shoulders in her.

a plane perpendicular to the axis of the container. At its lower end the outer shell 6 engages the base 5 of the inner shell. This construction at the opposite ends of the shells effectively locks them against relative longitudinal movement, while permitting free relative rotative movement, once the parts are assembled.

When the cap I is in place with its lower end engaging an annular shoulder 24 presented at the top of the larger portion of the base 5, it completely encloses the outer shell 6 and is frictlonally locked to said base in a well known man- The friction, however, is not so great but that the user readily will be able to assemble the cap.

Since the cap I when in service engages the base member of the inner shell I and since there is full clearance between the cap and the outer shell, relative rotation between the inner and the outer shells is impossible and there will be no danger of the lipstick cartridge being crushed against the top of the cap.

As shown in Fig. 4, there is formed in one edge of each slot I5, I6, near the top, a protrusion 25 which acts as a stop to limit the upward movement of the cartridge carrier since it stands in the path of the upper pair of pins 21], 2i. Also, the opposed walls of each slot terminate at the top in complementary bevelled portions 26 and 21 which, when the parts are assembled, overlap one another, giving an optical illusion of continuity except for a slight line which is unnoticeable unless attention is directed particularly to it. The illusion is further enhanced" by bevelling oppositely the different edges of each shell section so that the slots appear to be out along a common diameter.

As the inner shell is molded, the walls of the slots I5 and I6, respectively, flare outwardly toward the top. In this manner, there is provided an adequate opening at the upper ends of the slots readily to admit the protruding pins on the opposite sides of the carrier, which is the first step in the assembly of the parts. It will also be noted that such construction facilitates removal of the shell from the molding core.

After the cartridge carrier 3 has been placed in the inner shell I, the latter is inserted endwise into the outer shell 6. In performing this operation, the two cylindrical sections are pressed together against their natural tendency to maintain their molded form and entered into that end of the outer shell which is opposite the recess 23, the entry being facilitated by an internal bevel formed at the lower end of the outer shell 6. Thereafter, the inner shell is pushed up into the outer shell until the upper pair of pins 20 and 2| are entered into the lower open ends of the helical grooves I! and I8 which, as before stated, are disposed apart. Then the two shells are given a complete rotation, one relatively to the other, to enter the lower pair of pins I3 and I4 into the lower open ends of the two helical grooves. By this same rotation of the two shells, the base portion 5 of the inner shell is brought up against the lower end of the outer shell. At that time, the boss 22 at the top of the inner shell comes into register with the annular recess 23 in the outer shell, whereupon the sections of the inner shell, being under stress, will spring out and seat in the recess, thereby locking the parts together in assembled relation.

While two pairs of pins are herein shown, variations in the number and locations of the pins may be made, if desired. For'example, two pins might be employed in one slot, with only one pin in the opposite slot. In such case, an improvement in operation would be manifested over the operation of structures of the prior art. However, in order to achieve the best results, two pairs of pins as herein shown and described should be employed, such an arrangement serving at all times to maintain a uniform resistance to any force tending to disturb the stability of the carrier in its up and down movements.

The invention in its broader aspects is not limited to the precise construction shown and described, as many changes may be made in the details thereof without departing from the main principles of the invention or sacrificing its chief advantage. For instance, if the parts were made of metal, as they could be, then the outer shell 6 would be made in two parts, instead of one, in order that one part could be formed with helical slots and the other fitted over it to close the slots at their outer sides or convert them into grooves to receive the carrier pins. These are features of manufacture and do not in any sense limit the scope of this invention.

Having thus described my invention, what I claim is:

1. A lipstick holder including, in combination, a cartridge carrier having three later-ally projecting pins, two located on one side but at relatively diiferent levels and the other at the diametrically opposite side and at a level corresponding to that of one of the opposite pins, an inner shell member presenting a bore to accommodate said carrier and formed with two longitudinal guide slots for the carrier pins, and an outer shell member formed with two helical grooves of equal pitch and disposed 180 apart to receive and make a close fit with the carrier pins, said shell members being relatively rotatable, in one direction to project the lipstick cartridge outwardly from the bore for use and in the opposite direction to retract the lipstick cartridge into the bore.

2. A lipstick holder including, in combination, a cartridge carrier having two pairs of laterally projecting pins, the pins of each pair being located diametrically opposite, with one pair at one level and with the other pair at a different level, an inner shell member presenting a bore to accommodate said carrier and formed with two longitudinal guide slots for the carrier pins, and an outer shell formed with two helical grooves of equal pitch and disposed 180 apart to receive and make a close fit with the carrier pins, said shell members being relatively rotatable, in one direction to project the lipstick cartridge outwardly from the bore for use, and in the opposite direction to retract the lipstick cartridge into the bore. 3. A lipstick holder as in claim 2 characterized in that the distance between the pin levels is equal at least to one-half the pitch of the convolutions of the two helical grooves in which they travel.

4. A lipstick holder including, in combination, a cartridge carrier having two pairs only of laterally projecting pins, the pins of each pair being located diametrically opposite, with one pair .at one level and with the other pair at a different level, the two pins at each side being disposed in vertical alignment with each other, an inner shell member presenting a bore to accommodate said carrier and formed with two diametrically opposite longitudinal guide slots only through which the aforesaid pins project, the two pins at one side riding in one of said slots and the two pins at the opposite side riding in the other of said slots, and an outer shell member formed on its inner face with only two helical grooves of equal pitch and disposed at apart to receive and make a close fit with the projecting ends of said carrier pins, the two diametrically opposite pinsof each pair being disposed in said grooves, respectively, said shell members being relatively rotatable, in one direction to project the lipstick cartridge outwardly from the bore for use, and in the opposite direction to retract the cartridge into the bore, by the cooperation of the two said helical grooves and the two said pairs of pins.
