This invention relates to improvements in lipstick cases, and, more particularly, to novel propel-repel cases embodying coil compression springs contained in and actuated by a rotatable base member.

In my prior application Serial No. 625,801, iiled October 31, 1945, I disclosed and claimed a lipstick case consisting of an outer shell with a rotatabe base attached thereto, the shell having a cage or fenestrated retaining device fitted therein to serve as a retainer for a coil compression spring, to the free end of which a cup is attached, the cup receiving a lipstick, and movable in the shell by the spring. In this form, the cup rotates with the spring as the latter is actuated by the rotatable base. Under such conditions, the form of the cup and of the lipstick carried therein is essentially restricted to a circular or cylindrical type.

I have now found that lipstick cases of the compression spring actuated type can be utilized in cross-sectiona1 shapes of any desired contour, and so constituted and arranged that the lipstick cups are prevented from rotation, yet are freely movable along the longitudinal axls of the device.

The improvements of the present invention will be more clearly understood by reference to the accompanying drawings, in which certain preferred embodiments are shown, by Way of illustration only, as it is not intended to be lfmited to the forms here shown, except as such limitations are clearly imposed by the appended claims.

vFigs. 13 `and 14 are horizontal cross sections taken' on lines l3-l3, lll- I4 of Fig. 11.

The lipstick cases of the present invention consist essentially of an outer, curvilinear shell with a rotatable base attached thereto, the rotatable base having a depression therein or forming a Well to receive a substantial portion of a coiled compression spring. A barrier is included in the hollow base at an appreciable distance from the bottom, and of such dimensions, and so oriented, that the helical turns of the spring will have normal bearing engagement against the barrier and yet can thread their way past the barrier without distortion or binding. The bottom of the spring is preferably loosely disposed within the base and is so congured that the lower end of the spring cannot thread its Way past the barrier. The upper end of the spring is attached to a lipstick cup which is sdably mounted Within the shell, the cup being so mounted within the shell that it cannot rotate. The non-rotatability of the cup is assured by the particular shape of the shell and of the cup where they are both curvilinear but noncylindrcal, and, when cylindrical, by providing grooves or other means in the shell and the cup for mutual engagement. For cylindrical members an extra sleeve, having a radial slot engageable by a stud or protuberance on t-he cup, may also be used to assure the desired slidability and non-rotation thereof.

In operation, the lipstick case will be actuated by rotating the base, which during its rotation collects or releases a certain amount of the coiled spring from the cavity within the base, thereby causing the cup to rise or descend within the shell or casing.

The lipstick cases herein are characterized by (1) simplicity of parts; (2) simplicity of assembly; (3) unusual shaped pieces of cosmetic which are more suitable for application to the ips.

Where unusual shapes of lipsticks are used, the swivel type cases herein will elevate and lower the lipstick mass without rotating the same in its longitudinal reciprocating travel. As will be shown more in detail herein and in divisional application, Serial No. 54,625, cosmetics or lipstick masses can be made in tear-drop crosssection, diamond cross-section, and square crosssection, so that as they are used, there will always be a point or edge available for application to the lips to permit the forming of a sharply delineated line on the lips.

Another and important advantage of the devices herein, and particularly with reference to the non-circular, curvilinear containers, resides in the fact that the shape of the container permits the base to be snapped into place with great ease. An additional advantage of the cup-base construction resides in the fact that all the spring pressure, when the spring is compacted below the barrier pin, does not tend to push the base away from the sleeve. Furthermore, in the present case, the free sWiveling of the base acts to let the spring compress and decompress without distortion.

Considering the individual structures more in detail, the form illustrated in Figs. l. to i Will be considered rst. According to this form of the invention the lipstick case comprises a curvilinear shell or case lll, a rotatable base or cap 2li, a cup 3D, and a spring 4B.

The shell or casing il? comprises a generally cylindrical body portion il of circular cross-section, a domed or peened over top l2 deiining an aperture I3, a bottom lll, and a horizontal groove ,I

`|55 adjacent the bottom and parallel therewith :and defining an internal ridge i6. While the groove [E vis shown as continuous, a rovv of spaced indentations or depressions can be used, Yin which case the ridge 'I6 would be comprised lof spaced,

`'formed in the outer surface of section 2l and adjacent the shouldered flange. The collar or body portion "2l yand the flat base 22 define a central space or cup 25 into which is freely received the bottom compressed portion il of spring 4d. AA Vbarrier pin '25 fis tted in a diameter of the 4body 2l., and oriented at such an angle as to equal one-half -of the .pitch of the unexpanded or free turns l2 Vof the spring. At its upper end 43 the 'spring is secured to cup 3E by means oi a hollow rivet 421. The free end 45 of the spring may be Ibent as shown to insure its engagement and retention by vthe barrier pin 26 when the spring is rotated to its full expanded length. Normally, the lull, expanded `length of the spring will exceed the over-all length of the casing l0, so as to insure 'that lthe tip of the lipstick carrier or cup 3G will project through ythe open mouth or aper- .f

ture T3 ofthe casing.

Referring now to the carrier Si), this Will be seen 'to comprise a cup-shaped member `having a Wallportion-l.,.abase 32 .apertured to receive securing rivet E4, and provided with spacing knobs or ridgesSB. The cup may be provided further with a pair of spacers or ridges 3ft which are adapted to engage therridge l 8 formed on the inside of the casing by the groove ll, the interengagement of the ridge I8 and beads Sil serving to prevent the `cup 30 from rotating in the Vcasing 10,. yet permitting its free movement lin and valong the casing vin either direction. The cup 3^ is adapted to extend beyond the lip or opening 13 'to lpermit full access to the lipstick mass 50, 'which is contained therein, and to permit the ready 'removal of the lipstick stub and the insertion of a fresh lipstick mass.

In `the form vshown in Figs. 1 to 4, the rotatable member 'or cap '25 has been shown With a solid bottom 22. In the forms shown in Figs. 7 to 14, theibaseor'rotatable member 2li is bottomless and forms, essentially, a continuous cylinder 2l having a flanged or knurled knob 23. As shown in Figs. 11 Vand 12, the inner wall of the cylinder 2| may be provided with a helical groove 21 comprising one or more turns, the pitch of the groove being equal to the free pitch of the expanded spring. Where the rotating member is provided with a helical groove, the barrier pin 26 will be dispensed with.

Considering the form illustrated in Figs. rI to 14, a tubular casing l0, of curvilinear, ovoidal cross-section, has a major circular edge 0r Wall section 'l i., an axially opposed circular section 12, and convergent sides 13, 'M The tubular casing is provided with the usual domed or peened end l5, defining an aperture to receive a conformed lipstick holder or cup 30o having the spaced horizontal ridges 33D therearound secured to or formadas part of the wall section 3lb. The base of the cup 32h is secured to the compression spring le in the usual manner by hollow rivet 44. A base or cover plate 16 of generally ovoidal shape is provided With 'studs or upstanding portions 'l-l., 1.3 at the ends of the .major axis, and ythese studs are tted into Vskirts 'Ha, .12a .formed at the bottom of .the casing l0, the ,parts being secured by the usual pins ES. The .lipstick mass 'i9 is of tear-drop shape, as shown, and thisshape insures a linear edge -at .all times, together with fiat or round application sur'fa'o'es to permit lthe application -or formation Yor any desired contour of lipstick rouge tothe lips.

It will -noW be appreciated vthat there'has been provided novel lipstick .cases or" the .propel-.repel type which are adapted to use lipstick masses of varying cross-section, ,yet which use controlling or operating mechanism o 'uniform structure and mounting and Which .permit the variation of casing parts and 4lipstick carriers Withoutreduiring any fundamental variation in 'the operating mechanism. It will also be appreciated that there has been provided a novel lipstick caseand operating mechanism v/hich is spring-driven, yet in which the spring is never exposed Ato conditions tending to bind or cause the same vto so 'that the spring, being ffr'ee'ly rotatable in the casing, under operating conditions, will no't twist or become distorted and lbreak yduring use.
