10 Claims.

This invention relates to lipstick holders used for housing lipstick and rendering the same readily available for application to the lips. More particularly, the invention relates to certain improvements'in rotary lipstick holders, i.e., holders of the type in which the lipstick is housed in a cylindrical container and is projected therefrom for use by rotation of an operating head.

General objects of the invention are to reduce the number of'parts required in a rotary lipstick holder, to simplify the construction, and to improve the construction from the standpoint of economy and reliability when manufactured on a quantity production basis.

A more specific object of the invention is to provide a rotary lipstick holder which can be readily assembled and which will operate satisfactorily without requiring undue accuracy in the manufacture of parts.

Another object of the invention is to provide a rotary lipstick holder with enlarged and improved bearings for the essential moving parts, thereby minimizing the liability of jamming in service.

Various other specific and detailed objects of the invention will be obvious from the accom- Panying disclosure.

Fig. 1 of the drawing is an elevation of a complete lipstick holder embodying the present invention. On the original bristolboard drawing filed in the Patent Oflice this figure is oversize with respect to the dimensions customarily employed in manufacturing lipstick holders.

Fig. 2 is a central vertical section on the line 2-2 of Fig. 1, but on an enlarged scale.

Fig. 3 is a horizontal section on the line 3-3 oi Fig. 1. I

Fig. 4 is a. perspective view of the reciprocatory carrier incorporated in the lipstick holder.

Fig. 5 is an elevation of the casing, shell, or cylinder in which the carrier moves.

Fig. 6 is a perspective view of the operating head which is incorporated into the lipstick holder. 7

Fig. 7 is a perspective view of an operating element that is attached to the head shown in Fig. 6, and which serves to transmit rotary motion to the carrier. I

Fig. 8 is a fragmentary vertical sectional view of the upper end of the lipstick holder, showing a slightly modified construction.

With the exception; of the operating head shown in Fig. 6, the various parts are preferably made of sheet metal (for example, brass); and as usual, the thickness of sheet ated in the drawing.

A cylindrical sheet metal shell or casing, designated as a whole by "I, has its upper portion necked in at. H and its upper and formed into an inturned flange I2. On the outer wall of the cylinder Hi there are numerous indentations such as i3, which are all part of one or more series of indentations, corresponding to a single or multiple thread respectively. These indentations are preferably of spherical form, 1. e., the surface of the indentation corresponds in shape to the curved surface of the segment of a sphere. Preferably these indentations are arranged in vertical rows circumferentially separated on the cylinder by an angle of 90, as shown in the drawing; but all of the indentations are spaced along a helical path or paths extending longitudinally of the cylinder 10. The particular arrangement shown in the drawing corresponds to a double thread and therefore involves two interspersed parallel helical paths, half of the indentations lying on one path and half on the other path. Since the shell is made of sheet metal, the in.- dentations 13 are accompanied by corresponding spherical protuberances H on the interior of shell i0. Adjacent the bottom 01 the cylinder l0 there is provided one or more instruck spring tabs l5 which are utilized in assembling the lipstick holder.

The carrier, designated as a whole by It, is preferably formed in one piece from sheet metal. It comprises a bearing skirt IS, a socket 20, and an annular flange 2| which acts as-a connecting means that unites the skirt and socket. On the exterior of the skirt there is formed a male thread 22 of rounded cross section. In the particular form shown in the drawing'this thread is a double thread, corresponding to the double thread arrangement of the protuberances H. The annular flange 2| is pierced by two

arcuate slots

24, 24. At its bottom the socket is provided with an inwardly extending annular head 25 (Fig. 2), which acts as a stop for a lipstick ,8 inserted into the socket.

The operating head 23 shown in Fig. 6 may be made in a single piece on an automatic screw machine' It comprises upper and lower

circular flange portions

26 and 21 separated by an annular groove 28. On its top the head is provided with an integral hollow boss 29 having much the same configuration as the shank end of a conventional tubular rivet.

' The operating member shown in Fig. 7 comprises a tubular bottom .portion 3| having an metal is eizaggerend wall 32 that is pierced at its center with an octagon shaped hole 33. Projecting upwardly from the. tubular portion M are two standards I 34, 34, each of which is of arcuate cross section, 5 since the standards are continuations 0e sectors otthe tubular portion 8|. In assembling the members of Figs. 6 and '7, boss 29 is telescoped from the bottom through, the hole 33 and upset in a conventional manner to rivet the'two parts together. When so assembled, the head 23 and the operating member are related as shown in Fig. 2, so that rotation of head 23 rotates member 38. When boss 29 is inverted, some of the metal of the boss flows into the corners of octagon hole 33, thereby locking member 30 against rotation relative to head 28. The carrier I8 is screwed into the cylindrical shell or casing ill from the bottom, the tab it being located on a continuation of the helical path established by protuberances H. The

standards 34, II are inserted from the bottom.

through the

slots

24, 2 ,4, and the upper flange oi the head 26 is forcibly telescoped into the bottom of the cylinder Hi. This causes the spring tab- IE to snap into the annular groove 28 and thereby hold the parts together. It will be noted (more particularly from Fig. 2) that the standards 34, 3! make a bearing lit with the exterior surface of the socket 29 and also with the bearing surface i'ormed'on the interior surfaceof the re- -riucedportion H of the tube Ill. The cylindrical surface of the skirt l9 also makes a suitable bearing fit on the interior cylindrical surface of the shell IO. Thus the various parts mutually engage movement without danger of jamming in service. with the tab I! located in the annular groove 20, the head 23 may be freely rotated withrespect to the casing It. When so rotated, the

standards

34, 34 impart rotary motion to the carrier I8. Rotationof the carrier 18 causes the hellcally disposed protuberances I to exert a longitudinal force on the thread 22 with theresult that the'carrier is moved longitudinally in the casing ll. Thus, the lipstick S-is readily projected for use and then retracted again for car-.- riage.

Preierably the holder is provided with a removable dust cap 88 which telescopes over'the top of the holder and makes a convenient friction flt with the exterior of easing I0. I! desired, this can may extend the full length of casing l8. However, I prefer to have the cap 35 extend only partoi' the length oi casing l0 and then engage the end of a sleeve 86 which covers the lower portion of casing l0. Sleeve 36 may extend from head II to any desired height along the casing, though in the drawing it extends about half way. Conveniently the sleeve 30 is irictionally secured to casing l0: and the friction may bemade so great that the sleeve is not readily removable from the casing.

The modification shown in Fig. 8 diilers from Figs. 1 to '7 only in that it embodies a shell I 0a, the upper portion otjwhich is reduced in two steps Ila-and I I b. The interior surface of steplib then acts asa bearing for the upper ends oi standards 34, I}.

m In compliance with the patent statutes, I have shown the best form in which I have contemplated applying my invention. It will-be understood. however, that the disclosure is illustrative of the invention, not limiting.
