Claims. (Cl. 20G-56) This invention relates to lipstick holders and is particularly concerned with such holders adapted to retain and eject lipsticks of elliptical or other non-circular crosssection.

A primary purpose of the invention has been to provide a lipstick holder of the character mentioned having a simple and reliable mechanism for ejecting and retracting the lipstick so that it may be readily and quickly shifted to a position for etlicient use or to a position in which it is concealed within the housing and protected against undesired contact with the user or the removable cover.

Lipstick holders as previously constructed, with mechanism for ejecting and retracting a lipstick, have been subject to a variety of objections. In most instances they have involved quite complicated and expensive constructions, requiring a relatively large number of parts, for achieving the desired results. Moreover, some have involved mechanisms which are slow in their action. These have required an excessive number of turns of an operating element in relation to the main casing of the unit to bring about the desired ejection and retracting of the lipstick.

In achieving the purposes of the present invention the lipstick and its carrier have been made of non-circular, preferably elliptical, cross-section and advantage has been taken of this to eliminate the provision of extra means for preventing the rotation of the lipstick and its carrier in relation to the main housing or casing of the unit. Moreover a very simple and reliable mechanism has been provided for projecting and retracting the lipstick. This involves few parts which may be made economically and which serve to provide full movement of the lipstick carrying cup, from its lowermost to its uppermost position, on two to three revolutions of the base of the holder in relation to its main outer casing. Actually, on each use of the lipstick it is projected and retracted suiciently with less than a single revolution of the base of the holder. The arrangement is such that a single revolution will shift the lipstick about half an inch. This is more than adequate to carry it from a concealed and protected position to a proper Working position. It will be understood that the zone of movement of the lipstick and its carrier will be shifted progressively upward as the lipstick is consumed.

The construction of the improved lipstick holder is such, furthermore, that it eliminates binding of the parts in projecting and retracting the lipstick. Prior constructions, particularly those provided with fast acting mechanism for shifting the lipstick, have had a serious tendency to bind.

A special feature of the present invention is the provision of a lipstick shifting mechanism which involves the cooperation of two threaded tubular elements telescopically arranged and adapted to shift the lipstick to its full extent` upon only two turns of the tubular elements in relation to each other. Moreover the threads 2,823,796 lPatented Feb. 18, 1958 are of more than single or double lead, preferably fourlead, so that the forces exerted between the cooperating threads are distributed evenly, both around and along the tubular elements, with the result that the action is smooth and the binding tendency is eliminated.

Other objects, features and advantages of the invention will appear from the detailed description of a preferred embodiment of the same which will now be given in conjunction with the accompanying drawings, in which:

Referring now to the drawings, there is shown a lipstick holder adapted to receive a lipstick of elliptical cross-section. The holder is provided with a main casing 10, the upper portion 11 of which is of elliptical cross-section and the lower portion 12 of which is of circular cross-section. An intermediate portion 13 of the casing has parts of its wall inclined or tapered inwardly from the top of the cylindrical portion 12 to the bottom of the elliptical portion 11. Cylindrical portion 12 is of a diameter slightly greater than the major axis of the elliptical cross-section of the upper portion 11. This is to provide a shoulder 14 for cooperation with the bottom of a removable cap member tot be hereinafter described. Portion 13 of the casing merges smoothly into the contour of the upper elliptical portion 11 and the lower cylindrical portion 12.

A base or bottom closure for the holder comprises a cup 15 of cylindrical cross-section, having a diameter substantially equal to that of the portion 12 of the casing so that, in eifect, it constitutes a continuation of the casing and has is upper edge abutting the lower edge of the casing along a line 16. Within the cup 15, and secured to the latter, is a tubular insert member 17. This may be secured in any suitable way to the cup 15, as by a press t. One or more tabs 17a, formed by horseshoe shaped slits, may be provided on the member 17 to project slightly from the outer surface thereof and cooperate with the inner wall of the portion 12 of the casing to provide a limited frictional resistance to the relative turning of these parts. Portion l2 of the outer casing is provided with an inwardly extending bead formed by an annular indentation 18 extending around the same. lf desired the bead may be replaced by two small indenlations at diametrically spaced points. The bead or indentations will cooperate with an annular indentation 19 provided in the member 17. The arrangebe rotated in relation to the casing but is held against axial movement in relation to the casing. -Atl--an intermediate point the member 17 is provided with an inwardly extending shoulder20 from which extends upwardly a reduced neck portion 21. A threaded sleeve 22 extends upwardly from the bottom of the cup 15, through the reduced neck 21, to a suitable distance Vabove the latter. This sleeve is arranged to rotate with the cup and the member 17. Any suitable means may be provided for insuring joint rotation of these-parts. For example, there may be a sufliciently tightfrictional tit between the sleeve and the reduced neck 21 for this purpose. Or the sleeve 22 may be welded or otherwise lirmly secured to either the cup .1S or member 17, or to both.

Sleeve 22. `is provided with an internally active, fourlead thread of relatively steep pitch. This thread may suitably be formed by a rolling operation so that it projects both inwardly and outwardly. But-in the 2cmbodiment disclosed the sleeve is active as an internally threaded element. lt has been found desirable 4to provide the thread with a pitch of about .l"-so that the overall lead of the four-leads of the threadA is one-half inch. Thus there are actually four separate 'threads around the sleeve 22, these being spaced successively at the indicated pitch and each having an actual pitch of .5". In any given cross-section the four leads of the thread are 90 apart, as shown in Fig. 5. At its upper` endthe sleeve 22 is provided with an inturned shoulder` orl ange 25 providing a central circular opening.

Slidable within the opening defined by the shoulder'ZS and guided thereby is a tubular member "24'l1aving-a slightly enlarged lowerV end portionl 25 provided'withfa four-lead screw thread adapted to cooperate with fthe screw thread formation in the sleeve 22. It will be understood that the thread provided in the portion Av25 V,of member 2d is of the same pitch and overall `lead -as that provided in the sleeve 22. At its vupper end the member 24 has a reduced portion 27 which` is preferably square in cross-section and which extends through .an opening of corresponding -form and dimension in the bottom of a lipstick retaining cup 26. The top of the extension 27 may be peened over to firmly secure the cup to the `top of member 24. Thus aunit is formed comprising the cup and a downwardlyvextending hollow stem with a male, `threaded element at its lower end. Cup 26 is ofelliptical-cross-section and is arranged zto slide freely but rather snugly `within the upper portion ll otA the casing. `Due to the elliptical contour of the cup and ot the casing, -relative rotatiombetweenhese parts is substantially prevented. Adjacent its bottom'the cup 26 is providedwith inwardly extendingnibs 28 adapted to grip the bottom-of an inserted lipstickll. Preferably the top portion lof thecup'26 is of slightly enlarged inside diameter, as indicated at -29 (Fig. l),` to facilitate introduction of the lipstick linto the cup.

lt will be apparent from the foregoingthatsince the cup 2o and the tubular stem 24 are heldA against rotation in relation to the casing while a sleeve 22 is held against rotation in relation to the bottom Vclosure 1S, 17 relative rotation between the bottom closure` and the casing will bring about relative rotation between the

sleeve

2,2 and member 25. This will cause' the member 24 to be lifted or lowered, depending Yupon the direction of relative rotation. Moreover, byvirtue of the screw thread formation in the

parts

22 and 24, `the relative axial movement between these `parts will be quite rapid, i. e. approximately one-halffinch :for-.each revolution inthe preferred constructionspecied. The arrangement is such that the bottom 'closure and casing maybe turned in relation to eachother to the extentof between two and three revolutions so that'fthe .lipstick and-its retaining cap may be elevated",andlowered lthrough a distance of between l andY 1:1/2. Further upwardmovement `is prevented by the 'cooperation of the lenlarged portiont25 of' member 24 with"the ushoulder Provided by inturned liange 23 of sleeve 22. Relative downward movement of the parts is limited by the engagement of the bottom of the stem 24 with the bottom of the cup 15.

A removable cover 31 is provided to close the open top of the casing 11 when the holder is not in use. This cover has its main portion of elliptical contour conforming with that of the upper portion of the casing 11 and of a size to provide afree sliding clearance, say .005, in relation to the latter. At its lower end the cover has outwardly inclined or flaring wall portions 32B conorrninsI with the slope of the corresponding walls of portion i3 of .the casing. The bottom edge of the cover is larranged to abut the shoulder 14 on the casing when the cover is fully applied. To retain the cover reasonablyy lirmlylin place a pair of nibs 33 is preferably provided in the portion 13 of the casing for fric tional engagement with the inner surface of the cover. As shown in Figs. 2 and 6 the nibs are preferably located in alignmentwith the ends of the major axis of the elliptical cross-section of portionl of the casing.

in Fig. ltlie lipstick is shown'full length, as when first inserted in the holder. "The retaining cup 26 and the stern 24 are in their fully retracted ,position kso that the Vtop of the lipstick is substantially flushwitli the outer end of the casing 10. vlCnEig. 2 the lipstick is shown as having beenpartially consumed andprojects only slightly beyond the upper end of the casing 10 with ,the lipstick retaining cupand the stern 24 in partiallyelevated position. l t is not necessary torctract 'the stemand the, cup further than this, so long as some clearance is'provided between the top of the .lipstick and the inner surface oft the cover 31. The arrangementis such that when4 it isdesired to use the lipstick, the cover 131 is removed and less than a full revolution of the .bottom closure 15,17 ',inrelation to the casing lit) is sulicient to project the lipstick for effective use. Correspondinglya small vturn of 'thebottom closure of the holder in relationlto the'cas'ingl() isfsuiiicientto retract the lipstick to a position yin which the'top cover may be applied without engaging the yupper .end .of the lipstick. Or course' the lipstickmay be retractedto a further extent, 'if desired, so that itis completely within the casing 10; a greater extent of relative turning of the bottom closure andthe casing is then required to project it again. However, as explained, between two and three turns of the bottom closure in relation to ,theV casing will shift the lipstick retaining cup from its lowermost toits uppermost position.

While a preferred embodiment of the invention has been described in considerable detail, it will be Understood that various changes may be inade'in the construction and arrangement of the several parts without'departing from the principles and scope ot` theV invention as deined by the appended claims.
