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. This application is a division of my application Serial No. 745,701, filed May 3, 1947, for Lipstick cases In my prior application Serial No. 625,801, filed October 31, 1945, I disclosed and claimed a lipstick case consisting of an outer shell with a rotatable 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-sectional 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 axis 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 illusration only, as it is not intended to be limited to the forms here shown, except as such limitations are c early imposed by the appended claims.

The lipstick cases of the present invention consist essentially of an outer, non-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, 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 configured and arranged 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 slidably 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.

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 cupto 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 cosmetics which are more suitable for application to the lips.

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 my said parent application, cosmetics or li stick masses can be made in tear-drop cross-section, diamond cross-section, and square cross-section, 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 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 spr ng 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.

3 detail, the form illustrated in Figs. 1 to will be considered first. According to this form of the invention, the lipstick case comprises a non-curvilinear or polygonal shell or case fill, a bottomless, rotatable cylinder 2!, a cup 36a and spring td.

The base 20 comprises a generally cylindrical bottomless body portion 2i with a shouldered flange extension 23. The collar or body portion 2i and the cover plate 56 define a central space or cup 25 into which is freely received the bottom compressed portion 4| of spring 4t. A barrier pin 26 is fitted in a diameter of the body 2i, and oriented at such an angle as to equal one-half of the pitch of the unexpanded or free turns 42 of the spring. At its upper end 43 the spring is secured to cup 39a by means of a hollow rivet 44. The free end 45 of the spring may be bent as shown to insure its engagement and retention by the barrier pin 26 when the spring is rotated to its full expanded length. Normally, the full, expanded length of the spring will exceed the overall length of the casing to, so as to insure that the tip of the lipstick carrier or cup 39 will project through the open mouth or aperture E3 of the casing.

In the form shown in Figs. 1 to 5, the casing it! is a tubular member of square crosssection hav ing sides 6i and an open top 62 with a peened-in or shouldered edge 63. The walls El normally terminate in central bottom portions 6!! and depending angular edges or skirts 65. A flat cover plate 65 is provided with upstanding corner posts 6? which are fitted into and engage the skirts 55 and to which they are secured, in any suitable manner, as by pins or screws 88. Where desired, the depending angular edges or skirts may be dispensed with, and the corner posts will be lengthened to extend up into the corners of the tubular body section. The inner surfaces or edges of the studs or posts 81 are conformed to the periphery of flange 23 of the rotatable member 28 to permit the latter member to rotate freely therein. In the form shown, the cup 3011 is provided with sides 3la having spaced transverse ridges Sta engaging the walls of the casing. The bottom 32a will be secured to the spring 40 in the usual manner by hollow rivet 44. Thus it will be seen that the desirable advantages of a freely mounted compression spring engageable by a rotatable member to actuate a propel-repel lipstick cup in a lipstick case of square cross-section is readily effected by incorporating the principles of the present invention.

In the form shown in Figs. 6 to 12, a lipstick casing 35!, of generally diamond cross-section, has

opposed edges 8!, 8i, defining a major axis, and

82, 82', defining a minor axis, with sides 83 formed in and between the said several edges. The top of the casing is peened over, as indicated at M, and the edges 8!, 8|, are provided with skirted extensions, designated generally by the numeral spacing ridges 33c and bottom 320 secured by hollow rivet 44 to spring 40.

It will now be appreciated that there has been provided novel lipstick cases of the propel-repel type which are adapted to use lipstick masses of varying cross-section, yet which use controlling or operating mechanism of uniform structure and mounting and which permit the variation of casing parts and lipstick carriers without requiring any fundamental variation in the operating mechanism. It will also be appreciated that there has been provided a novel lipstick case and operating mechanism which is spring-driven, yet in which the spring is never exposed to conditions tending to bind or cause the same to jam so that the spring, being freely rotatable in the casing, under operating conditions, will not twist or become distorted and break during use.
