(Cl. G-56) 2 Claims. l

This invention relates to rotary holders for sticks such as lipsticks, that is to say to holders of the kind in which the stick is projected from the holder and withdrawn into it again by rotary motion. It relates particularly to rotary holders of the type that is characterized by a long, slender appearance. with cosmetic sticks (including medicinal sticks) of various kinds as will be apparent. At present they are used principally for lipsticks however. Accordingly for brevity I shall refer to lipstick holders substantially only hereafter.

Speaking generally, aholder of the type indicated consists principally of a tubular body shell and a second or base shell, also more or less tubular, connected together rotatably end to end, an elevator within the body shell to carry the stick, and an elongated member, such as a rod or threaded bar, extending from within the base shell to the elevator and reciprocable by rotation of one of the shells while the other is held stationary by the fingers. By rotation of one shell with respect to the other therefore, the elevator can be raised to project the stick from the body shell for use, or contrariwise .drawn back to return the stick into the body shell.

Heretofore it has been proposed to couple an elongated member to what may be called a base shell of lipstick holders, by means of a follower or vguide member fastened to the elongated member and slidable in but non-rotatable with respect to the base shell. The present invention provides a simpler mechanism for actuating the elevator. Speaking generally, the present invention contemplates a spiral connection between the elongated member and one of the shells, and a member fastened to the other shell and having a reciprocatory but non-rotary connection with the elongated member, both these connections being located adjacent the junction between the body shell and the base shell. The spiral con-l nection may, of course, be a spiral slot and pin connection, a threaded bolt and nut, etc. Also, the invention can assume various forms as will bounderstood. The forms of the invention which we prefer at present are illustrated in the accompanying drawings.

. In those drawings, Fig. 1 is a perspective view of a lip liner embodying the invention, its cap being in place. Fig. 2 is a longitudinal section of `the same liner and its cap. Fig. 3 is a similar section drawn to a larger scale. but with the cap omitted. Fig. 4 is a perspective of the serrated flat bar whichserves as the elongated member in thelpresent instance. Fig. 5 is a cross-section on Such holders can be used 2 the line 5--5 of Fig. 3. Fig. 6V is a view substantially similar to that of Fig 2, of a second form of this invention. Fig. 7 is another substantially similar View of a third form of this invention.

In the form of the invention shown in Figs. l to 5, the body shell comprises a main tubular section I and an auxiliary tubular section 2 set onto and fixed to the main section I. This construction of the body shell from two parts is primarily a matter of convenience however, and to provide a shoulder 3 to act as a stop to limit the movement of the cap 4 onto the body shell. An elevator 5 to hold the stick, say, a lipstick, is located in the body shell I-2 and is reciprocable within this shell so as to project thestick from the open end 6 of the body shell for use and retract the stick into the shell again for protection. Somewhat adjacent the opposite end of the body shell, an internally threaded nut I0 is firmly xed to the interior of the body shell. The elevator 5 is mounted on one end of an elongated threaded bar I I that projects through and meshes with the lnut I0. As shown, the threaded bar II may be a flat bar serrated at its edges so as to mesh with.

the threads of the nut IIJ. Also the threaded bar Il can be connected to the elevator readily by forming a bend or hook I2 on one end of the bar and hooking -this through a hole in the bottom of the elevator as illustrated.

The base shell also consists of two tubular portions in this form of the invention, againfprincipally for convenience of construction ofl the holder as a whole. The main tubular section I5 is closed at one end, and the auxiliary section I6 is set into the open end of the main section I5. A portion of the auxiliary section I6 of the base shell also sets into the adjacent end of the auxil. iary section 2 of the body shell, thus coupling the body shell and the base shell end to end. The couplings are such, by friction or otherwise, that the auxiliary section 2, and thereby the bodyshell, is held on the auxiliary section I6 of the base shell against the longitudinal stresses to which the device may be subjected normally. but at the same time the section I6 is rotatable within the section 2;'and the auxiliary section I6 is held in the main section I5 of the base shell at least sufficiently rmly to resist displacement by the normal longitudinal stresses to which the device may be subjected, and also so firmly that when the body shell is held and the main section I5 of the base shell is rotated, the section I6 rotate with the section I5 and within the section 2. Y

`The `base shell carries a diaphragm II adjacent the junction between the body shell and the base shell. As illustrated this diaphragm may be an integral end wall of the auxiliary section I6; as it were the diaphragm I1 and the tubular wall of I6 may constitute a flanged diaphragm. The purpose of the diaphrgam is to make a nonrotatable, but reciprocable, connection between the body shell and the threaded member. Since the threaded member I I is a flat bar in the present instance, a slot I8 in the diaphragm or end wall I1 through which the threaded member II extends into the base shell, will suilice for the purpose. The length of this slot is somewhat greater than the width of the threaded bar, and its width is a little greater than the thickness of the bar (Fig. 5). As a result rotation of I1 Will rotate the bar, but at the same time the bar can reciprocate through I1 freely.

In the present instance the cap 4 which serves to close the holder while the stick is retracted, not only sets over but also engages the body section I frictionally so as to be seated on and be held by this section. At the same time of course the body shell section holds the cap suiciently loosely to permit the cap to be set onto and taken off the body shell readily when desired. To these ends a narrow strip I9 of the material of the part I may be pressed outwardly to press against the inside of the cap 4, if desired.

The operation of the holder described is rather l obvious. When the cap 4 has lbeen taken off the holder, the section I or the section 2 (or both) of the body shell can .be held by the fingers of one hand while the base shell is rotated by the other hand grasping the section I5 of it. Rotating I5 rotates the auxiliary section I6, and therewith the member or diaphragm I1, and the latter in turn rotates the elongated threaded bar I I. Rotation of this bar in the nut I in the proper direction will reciprocate the bar of course, thereby pushing the elevator toward the opening 6 of the holder and projecting a stick carried by the elevator for use. Rotation of the base shell in theA opposite direction, relative to the body shell, will return the elevator and again withdraw the stick into the body shell I--2 for protection. When this has been done the cap 4 can be thrust back onto the body section I, and will be held thereon by friction until the stick is required again.

It will be noted from the foregoing, that when the body shell is prevented from rotating, and the .base shell is caused to rotate, the elevator will thereby be propelled outwardly or retracted inwardly, depending upon the direction of rotation of the base shell, but in either case the elevator will be caused to rotate at the same time that it engages in longitudinal movement. Should it be desired to cause longitudinal movement of the elevator without at the same time causing it to engage in angular movement, the base shell should be held in the hand and the body shell should be caused to rotate. Longitudinal movement of bar I I and hence of the elevator to which it is connected will be caused in this case by rotation of nut I0. In the previous case, the nut remained xed and stationary and longitudinal movement of bar Il and hence of its elevator 5 was caused by rotating the bar in the nut.

In the second form of this invention, shown in Fig. 6, a cap 30 is provided which is like the cap 4 of Figs. l and 2. It is removably mounted on a main tubular section 3I which corresponds generally to the main tubular section I of the earlier figures and is inserted into an auxiliary tubular section 32 which corresponds generally to the auxiliary tubular section 2 of the earlier figures. The tubular members 3| and 32 comprise the body shell of the present device. Similarly the base shell comprises two tubular sections, namely an auxiliary section 33 somewhat corresponding to the earlier section I6 and a main section 34 corresponding generally to earlier section I5. The tubular section 3I is xedly connected to the tubular section 32, and the tubular section 33 is mounted in and i'ixedly connected to the section 34. The section 33 extends upwardly into the body shell, and more particularly into the tubular section 32 thereof, and these two sections are provided with an annular groove 34 and an annular ridge 35 which cooperate to prevent axial movement between the body and base shells but permit angular movement of said shells relative to each other.

In the arrangement of the earlier gures the diaphragm I1 which forms the non-rotatable but reciprocable connection with the elongated member II is affixed to the base shell, and the cooperating spiral member or nut IIl is connected to the body shell. In the present arrangement of Fig. 6 however the connecting diaphragm 35 corresponding to diaphragm I1 is Iprovided in the body shell 3I-32 and the cooperating spiral member or nut 40 is connected to the base shell. Also the present arrangement illustrates that the stresses in holders such as here concerned are such that a nut 40 formed from tubing serves the purposes quite as well as a conventional nut such as is shown at I8. As before the elongated member, to one end of which the elevator 39 is connected, may be a serrated flat bar I I and accordingly the connection at the diaphragm may be a slot 31 corresponding to I8.

The operation of the arrangement of Fig. 6 is so like the operation of the device of Figs. 1 to 5 that the foregoing description of the operation of the latter will serve for Fig. 6 also.

The device of Fig. "I illustrates a still further simplification of the foregoing, namely the elimination, as it were, of the auxiliary section 2 of Figs. l and 2 and the auxiliary section 32 of Fig. 6. Here the cap again is removably mountable on the body tubular member 5I. In this instance however the body shell consists of this member 5I alone. The lower end of this body shell 5I extends into the adjacent end of the main tubular section 52 of the base shell, and is readily rotatable therein but not readily removable by longitudinal movement. The two may be tied together in this way by a circumferential bead 53 on one of them and a cooperating circumferential groove 54 on the other. The elevator 55 is mounted in body shell 5I for longitudinal movement therein as before, and is connected to the serrated flat bar 56 which meshes with a nut 58 carried by the auxiliary tubular member 51 of the .base shell and is held against rotation relative to the body shell 5I by a diaphragm 59 on the base shell and having a slot El! for the bar as before described.

The operation of the device of Fig. 7 is substantially as described with reference to Figs. 2 to 5, and hence need not be described again.

It will be understood that our intention is not limited to the details of construction and operation described above and shown in the drawing except as appears hereafter in the claims. It -is to be understood also that the claims are Lintended to include not only the elements mentioned in them, but the equivalents of those claims also.
