2 Claims.

This invention relates generally to holders for lipsticks, eyebrow pencils and similar soft pasty cosmetics, and particularly to holders of the type in which thecosmetic is adapted to be ejected and retracted by relative rotation of two parts of the holder.

Prior. lipstick holders have generally been constructed of metal, though there have been some eilorts to design a suitable holder which can be constructed of plastic materials. For various reasons'these Aefforts have not met with great success, plastic construction presenting. various problems which are foreign t metal construction, and which have not heretofore been entirely solved. Among these problems is the provision of a device which will not be excessively bulky, which will operate freely, which may be easily and quickly assembled, and which lends itself to plastic molding methods.

It is accordingly the general object of the invention to provide a lipstick holder of the ejecting type which overcomes in a satisfactory manner the various problems incident to plastic construction.

One problem in both metal and plastic holders which employ a slip cap is to prevent `the possibility of placing the cap on the holder while the lipstick is in partially ejected position, or the further possibility of partially ejecting the lipstick while the cap is in place on the holder, either of which operations results in engagement of the lipstick with the inner end of the cap, with consequent soiling of the inside of the cap. A further object of the invention isd accordingly the provision of a lipstick device in which this condition cannot occur.

Further particular objects of the invention have to do with the provision of a lipstick holder device of a simple plastic construction, which is easily and freely operable, easy of assembly, and with the provision of a novel and improved method of assembling a lipstick holder of the type disclosed.

Further objects, features, and accomplishments of my invention will appear in the course of the following detailed description of one present preferred embodiment thereof, reference for this purpose being had t0 the accompanying drawing, wherein:

Fig. l is a perspective view of the lipstick holder of the invention, with the slip cap removed;

Fig. 2 is a longitudinal medial section through the holder, the slip cap being in position;

Fig. 3 is a view taken as indicated by broken line 3 3 of Fig. 2, the slip cap being removed;

Fig. 4 is a transverse section taken on `line 4--4 of Fig. 2; I 1

Fig. 5 is a view showing a step in the assembly of the cosmetic holder with the ferrule;

Fig. 6 illustrates the next step in the assembly of the cosmetic holder with the ferrule; I

Fig. 7 is an exploded view illustrative ofthe assembly of the holder; and I Fig. 8 is a viewsimilar to a portion of Fig. 2, but showing a modification.

In the drawing, numeral I0 designates generally a cylindrical casing or barrel, preferably, though not necessarily, formed of plastic. Slidably received within this casi-ng or barrel I0 is the cosmetic cup or carrier II, also `preferably formed of plastic. Cupv II has oppositely projecting pins or lugs I2, which project through diametrically opposite longitudinal slots I3 formed in barrel Ill.` 'I'he pins or lugs may be formed integrally with the cup, though not necessarily so, the essential, broadly speaking, being merely that there be pins or` lugs I2 extending from the two opposite sides of the cup. The cup II `will of course be understood to be adapted to support the usual lipstick or other cosmetic, designated at L in Fig. 2.

In the preferred and here illustrated construction, the longitudinal slots I3 in barrel I0 extend from points near the forward end of the barrel to the rearward end thereof, the slots I3 thus being open ended at the'rearward end vof the barrel to receive the projections I2 of cup I I at the time of assembly.

Surrounding and'longitudinally movable on the barrel I0 is a ring I5, also preferably formed of f plastic, and which is preferably of about the same length as cup II, and has a straight boreofust slightly greater diameter than the outside diameter of barrel I 0, so as to provide a free turning and sliding fit. This ring is formed and functions as a nut element, its inside surface being here shown as provided with raised spiral thread elements I6, preferably of relatively coarse pitch, and the exterior surface of barrel Ill being formed with complemental thread elements in the form `of cooperating spiral grooves I1, which extend preferably from its base end to the ends of the Y slots I3, as shown. Of course by simple reversal, the raised spiral thread elements I 6 might be formed on the barrel I0, and the spiral grooves in ring I5. It is `of course evident that while I may preferably employ doublethreads, as` here indicated, this is not at all limitative on the invention. Rotation of ring I5 relatively to barrel I I0 effects translation of the ring along the barrel,

' ring' -I 5by squeezing the: latter so. that increased sufficiently toi accept the cup I I with its:

tively to the ring is prevented by the engagement of projections I2 with slots I3 in barrel I0, so that projections I2 ride around groove/201" as' the ringiis' rotated, while at the same timethe component of movement of the ring lcngitudi'nallyy of barrel I0' l I by reason of. engagement of cup projections I2 with one or the other of annular shoulders -2I of groove 20. Preferably, the'V circumferential'grooveZII.inside ringy I5 is at about the middle of the latter, and the thread elements Iiiextendronlyafrom thebottomof the ring to the groove; actually,.the thread elementsr IB.- may be reduced, in length until. they consist of nothing more thanl lugs-fI or pins, though. better and smoother actionfisgained'by making the elements spiral in form, and of some.length,.as indicated.

Barret I: isprovided atitsrearward end with an operating head 22, preferably of general disc s'hapepand of approximately the same or4 slightly larger diameter as ring and preferably formed of plastic.. The inner facel vofthis head 22 is formedwithv a groove or channel 23 adaptedto snuglyreceive: the end. or barrel IIl.. Head 22 is secured tightly on"v the 'end of barrel I- kin any suitablemanner; assuming; the. parts to be composediofanyfof the common types of thermo-plasticszthey may bei united tightly by touching the endl: portion'. offthe-y barrel with a suitable solvent suolrasacetone before inserting it into groove 23.

is imparted to cup cup and ring having thus been assembled with barrel IIJ, the operating head 22 may then be mounted on the end of the barrel in the manner already described.

Ihe lipstick is ejected or retracted by grasping and relatively rotating operating head 22 and nut ring I5. This results in movement of the ring longitudinally along barrel I0, with corresponding translation of cup II and the lipstickL.. Fig..2.shows the holder in fully retracted position; and with the slip capv25mounted thereon, the cap being understood to be provided with a-frictional t on the barrel, or with any other suitable retaining arrangement. Attention is directedv to the fact, that the slip cap is made long enough that its open end 26 comes immediat'elyad'jacent' to or against the end of ring I5 whern in the.- closedl position of Fig. 3, and that in such position, the end of lipstick L is somewhat spaced from the closed end o-f the cap. It willy nowr loer apparent that4 the. ring, I5 be,- rotated while thev cap is inf such position, the: ring willA engage the cap and. pushv the. latter ahead, so thatit is impossible for. ther end. of thev lipstick. to. engage the inside of the cap. Similarly, ifv the cap is placed on the devicewith the lipstick. in. partially ejected. position, itwill. engage ring I5 before its closed end strikes the end of the lipstick. Thus. complete. protection is provided againstv soiling the. cap byy the end of. the lipstick. The device islexcept'ionally freely operable, the short. ring. I5 slidingf and turning on the barrel without sticking, and the threads giving af smooth. and fire@v operating. characteristie. Thecuplugs slide freely inthe ringgroove 20., and thereis no. undesirable. friction between any ofthe wor-king parts.

Fig. 8 shows a modification, in whichY the. two

I oppositely facing annular Shoulders onV the, op.-

Preferably, head' 2.2` is formed* within groove 23,

with'pyramidalrprojections 24 adapted to engage the'. v'en'otches 24a at the open-.endsfof barrel slots '-I3,1so-as tosupport the slotted barrel'v and assure that both of the slots I3 will be of proper' and -equa'li widths throughout their lengths.` It will be'evldent thatthe head 22 affords a stcpshoulder for thel'ower end of the barrel.

A featureoff the invention` consists of a novel and impriwedfmethod. of assembly ofthe device, which may be" understood; readily by reference to Figs. 6, 7, and 8. Cup II is first assembled with its width is twrrlugs I2 (see-r Fig. 5).. The cup-isthen placed inside'th'ering audits lugs t2.v posititoned in alignment with circumferential groove 20 as illustrated in Fig'. 5'.- Release of. the-'pressure on the sides of the ring then causes they latter to spring back to:

circularshape, whereby the lugs I2 become engaged infgroove 20'. .The cupv and ring. as thus assembled; arethen assembled with barrel I0 by `inserting the slotted end of. the latter" in thev annuflarlspa'cebetween members II and I5 andengag ingv slots@ vr3` with lugs' stood. The: v'forrnationst atit'he open ends. of the I2, asi will be easily underslo'tsft'o facilitate: "flndng'the lugsv I2, and after `inserting the end of'thebarrel in' between the cup and ring, the ring Vis theny simply turned relativelyy to the barrel as itismoved onto the barrel, the

slots first finding the lugs I2`,. and when the threaded' portion of' the ring' reaches' the threaded `portion of the barrel; the threads readily start andthe ring screws properly onto the barrel. The

erating ring I5a are formed on the ends `of the ring, as at lla and. 2lb, preferably by annularly undercutting the ends of the ring, as illustrated, andin which the cup IIa has one upper lug i2a and one lower lug I2b projecting through the slots I3a of barrel Illa and. engaging the two shoulders 2Ia and 2lb. It will f'be evident that this form of the invention operates the same as that previously described. The advantage is gained that the cup is more readily assembled with the ring, it not being rnecessary to elongate the latter in assembly, since the cup may be readilyinserted simply byV tilting it' somewhat,4 asl will be perfectly obvious.

It will ofr course be understood that the drawings and description are for'illustrative purposes only, and that various changes in design, structure, and arrangement may be made without' departing from the spirit and scope of the invention or of the appended claims. l

I claim:

1. 1n a cosmetic holder, thev combination of a barrel having an open forward endfand having a longitudinal slot extending from a point near its4 said forward end through its rearward end, a cosmetic cup inside said barrel, a sleeve`rela tively rotatable aroundv and slidable along lsaid barrel', a circumferential groove' inside said sleeve and spa-ced substantially from both endsthereof, a lug projecting from the side of' sai-df cup through said longitudinalv slot in said barrel' into saidv circumferential` groove insaid sleeve, a head v on the rearwardV end ofL said barrel, a raised from both ends thereof, lugs projecting from opposite sides of said cup through said longitudinal slots in said barrel and into said circumferential groove, two diametrically opposed spiral thread grooves sunk in the outer surface of said barrel, and a pair of diametrically opposed raised spiral thread elements formed inside said sleeve exclusively between said circumferential groove and the end of said sleeve nearest said head engaging 10 in vsaid spiral grooves in said barrel.
