In France May 28, 1938 7 Claims (Cl. 206-56) 1 e V The present invention relates to cases for lipsticks which are to be held and operated with a single hand, so that the other hand remains free and can hold a handbag, a looking glass, and the like.

The invention is more especially concerned with cases of this kind constituted by a prismatic body devices of this kind: If, for any reason, the op:

erating wheel is operated while the cover is still 2 in the closed position or even is in an intermediate position other than the fully opened position,

the lipstick or other cosmetic may be crushed against said cover. I 'The essential feature of the present invention is to provide a case of the type described which eliminates this drawback. According to an essential feature of the present invention, I provide, between the body of the case and the operating wheel, locking means controlled by said cover for preventing any rotation-of'said wheel with respect to said body as long as said cover is not fully opened.

According to a preferred embodiment of the present invention, the locking means in question is constituted byan elastic pawl carried by the lateral wall of the case body which carries the operating wheel and which is adapted to cooperate with a toothed wheel rigid with said operating wheel, in such manner that said pawl, which is normally engaged in the teeth of said toothed wheel, is disengaged therefrom, by en tering a corresponding notch of the cover, only fora predetermined position of said cover corresponding to its full opening.

According to still another feature of the present invention, this elastic pawl is constituted by a spring arranged to brake the rotation of the cover with respect to the body and to lock it in a 50 yieldable manner in the fully opened position.

Other features of the present invention will 55 tion I will .be hereinafter described, with reference way of example, and in which;

to the accompanying drawing, given'merelyiby Fig. 1 is an elevationalviem-or'i;the ide of the operating wheel, of the lipstick case according to the invention, the operating wheel being supposed to have been removed andthe cover being in the fully opened'positiont A Fig. 2"is a vertical sectionv of'the lipstick case in the opened position, on the line 2 "2 of Fig. 11' Fig. 3 is an elevational View corresponding to m Fig. 1, but with the lid partly closed. Fig. 4 is a diagrammatie' perspective view showing the elastic pawl andthe corresponding toothed wheel as'they would be'vis'ible if'they 1 were cut away from the body on the line l-cofFig.2. Fig. 5 is a view on a larger scale of the upper left hand portion of Fig: 2."

As shown by the drawing, the lipstick case according to the invention, as illustrated by the 0 embodiment 'shown' by said drawing, includes-a hollow prismatic body I, for instance of square cross section, provided witha cover 2 adapted to pivot aboutapin'3.

On this case, there is journalled an operating'fi wheel 4, turning about pin 3 and the diameter oi which is such that its notched periphery projects on at least one side from'the body I. Thus'any one holding the case can'tturn theoperating wheel by means of the thumb of the same hand.

The cosmetic 'stick,which will be supposed to' be a lipstick, 5, is carried by a ilipstick holder 6 slidable inside a tubular sleeve-I 9 fitted in case I.

At its upper part, this tubular sleeve I9 carries a boss I9a in Whichthe end 2I of spindle 3'is screwed.

Two pulleys I I and I2- are journalled on said sleeve, respectivelyv 'atthebottom and top thereof. An endless cable I, passing-xaround these two pulleys so as to be driven. by them, carries a 40 piece 8 provided with aprojection 9 engaging in a boss I0 integral with the lipstick holder 6.

Pulley II is free to rotate on its support I9. Pulley I2 is a'driving pulley forcable I. It is coaxial with operating wheel 4 and angularly coupled therewith through a lug ,I3 rigid with the operating wheel and engaging in a recess I4 provided in pulley I2. I

Cover 2 carries a lateral extensionZZ, for in-. stance integral therewith, provided with a circular hole or bore 23 adapted to fit on a flange v 24 of case I, said flange forming a bearing for I 23. A curved spring 25 is housed in the recess inside flange 24, where itis fiXed at one end.- The opposed free end of said-spring 25 carries a lug 26. In the open position of cover 2, said lug 26 engages, through a gap provided in flange 24, into a notch 21 of the extension 22 of cover 2 (Fig. 1). For any other position of cover 2, the end 26 of spring 25 is pushed radially toward the axis of spindle 3 by the inner wall of the circular hole 23 formed in extension 22. Advantageously, as shown by the drawing, the portion of this inner wall which is to rub on head 26 is re inforced by a steel part 30 when pieces 2 and J 22 are made of a soft metal such as copper or a precious metal (Fig. 3).

The end 26 of the circular spring 25 carries, on its outward side, a pin 29 parallel to spindle 3.

The operating wheel 4 carries, on its inward side,

a coaxial toothed wheel 3| rigid with said operating wheel, for instance welded thereon. The diameter, size of teeth, and position of said toothed wheel are such that pin 29 engages with the teeth thereof when spring 25 is deflected inwardly (position of Fig. 3) and that it releases said wheel 3| when it is allowed to expand outwardly (position of opening of the cover of Figs. 1 and 4, in which the head 26 of the spring is engaged in the-corresponding notch formed in piece 22 of the cover).

This device operates in the following manner:

The case being held in one hand, it suffices to pivot the cover by moving it with the thumb so as to bring it into the open position shown by Fig. 1. Then, by turning wheel 4, also by means of the thumb, pulleys II and I2 are caused to rotate, and drive cable I, the element 8 of which transmits an upward movement to the lipstick holder 6, so that the lipstick projects more or less from case I.

Rotation of wheel 4 in the opposite direction causes the lipstick to slide'back into case I.

It will be readily understood that any rotation of: wheel 4--is:made impossible as long as the end 26 of spring 25 is not engaged in the corresponding'notch 21 of 22 {that is to say as long as the cover is not fully opened) because for any other position of the cover spring 25 is deflected inwardly as a consequence of its end 26 bearing against the wall 23 ofpiece 22, so that its pin 29 engages into the teeth of wheel ill and lock it in position.

On the contrary, as soon as the cover is fully opened, the end 26 of spring 25 snaps into notch 21 and pin 29. moved outwardly, releases wheel 3| so that the operating wheel 4 can be turned and the lipstick can be caused to project from case I.

Therefore, as said lipstick can be driven out from its case only when its path has been wholly cleared by'the full opening of cover 2, there is no possibility of said lipstick being crushed against the cover.

Furthermore, the engagement of lug 26 in notch constitutes akind of yielding locking of cover 2 in the opened position. A sufiicient thrust exerted on said cover overcomes this looking resistance so that the cover canbe brought into the closed position. The fact that spring 25 is then deflected inwardly and exerts a reaction on wall 23 produces a braking effect which, in particular, serves to maintain cover 2 in the closed. position thereof.

A lug 28 may beprovided for limiting in both directions the rotation of cover2. I Of course, the means for controlling the sliding movement of the lipstick inside case-I under the action of wheel 4 are not in any way. limited to those above described, which were given merely by way of example.

In a general manner, while I have, in the above description, disclosed what I deem to be practical and efficient embodiments of the present invention, it should be well understood that I do not wish to be limited thereto as there might be changes made in the arrangement, disposition, and form of the parts without departing from the principle of the present invention as comprehended within the scope of the accompanying claims.
