3 Claims.v (Cl. 20e-56) This invention relates generally to cosmetic containers and more particularly to such ccntainers in which means. arev provided for ad? vancing or retracting the cosmetic, material longitudinally of the device by the, movement Qf an operating handle longitudinally of the, djevice or by the movement of a. cap or similar operating member rotatably about the longitudinal axis of the container.

In cosmetic containers o1 this type, the prin,- cpal container is usually in the shape of a cylinder having an operating handle slidably mounted for movement longitudinally of the device or a rotatable cap at one end or the other which when rotated advances the cosmetic ma terial outwardly of the container for use. The propulsion and retraction of the cosmetic Inaterial is accomplished by means of a direct acA tion principle or by means of a screw principle. In accordance with such constructions a projection extends outwardly of the cosmetic carrier and is engaged in a straight groove on one hand or spiral groove in conjunction either with a straight groove or another spiral groove having its pitch in the opposite direction on the other hand. i

A primary requisite of such devices is that the cosmetic material be moved only when it is positively desired by the user. For example, the container is usually provided with a cap or cover member which closes the open end of the con-` tainer through which the cosmetic material emerges when in use. With the cover or cap in place in a ladys handbag or in her pocket, if the operating head or other actuatingmember is accidentally longitudinally moved or rotated, the. cosmetic material which is usually a soft cream mass, is forced up against. the inner surface of the cover or cap and becomes thereby deformed. Furthermore, a eer-tain amount of the cosmeticV material is thus wasted by reason of its adherence to the inner surface of the cover and makes for a generally unkempt and unsatisfactory condition.

As an example of this, it may be noted that when the cosmetic material is in its advanced or projected position, that is, lying outside of the upper part of the container, when the cosmetio is applied a certain amount of pressure is applied longitudinally of the cosmetic stick and the container. This pressure frequently results in the cosmetic material being pushed earn-v pletely into the container and there is danger that the upper relatively thin edges` of the oontainer may damage the lips. Also, when the cosmetic stick moves under normally useful pressure, it becomes difficult, to soV manipulate the cosmetic stick as to properly place the eosmetio material upon the lips of the user.

While various methods have been proposed to permit more positive control under. vario-11s corr ditionsf of the movement of the cosxrieliieY calill.. some have been open to the objection that mei! have either been unsatisfactory in operation 01' they have been too expensive? since, in the crdi-.1 nary commercial use at the present time, when the cosmeticr material becomes consumed, the, entire container is thrown away. Thus. where the container may be efficiently constructed at a lower production cost, the additional savings may he incorporated in improving the quality of the materials in the cosmetic itself.

It is, therefore, one of therprincipal Objects of the present invention to provide a novel and useful cosmetic container in which., by reason of the size, shape and positioning ,of certain of the parts as Well as the organization `ol the various components, economies both in manufacture of the parts and, in the assembly thereof result.

Another object herein lies inthe provision` of devicesv of the class described in whichthe move: ment of the cosmetic carrier is more Positively controlled whereby the same is resilerltly frictionally retained in any adjusted position thereof.

These objects and other incidental ends and advantages will more fully appear in the progs ross ci this disclosure and be pointed out in the appended claims.

Vreason of a bend 39.

cated by numeral I IJ comprises a cover II; an outer cylinder I2; an inner cylinder I3; and

a, cosmetic carrier I4.

The cover II is of inverted cup shaperinclud-r ing a cylindrical side wall I and a top wallv I6 and is preferably in the form of. a deep drawn -brass shell.

The outer cylinder I2 has both the upper and lower ends I1 and I8 respectively open and is,

provided with a spiral slot or channel I9. The

greater than the outer diameter of the inner cylinder I3. The parts thus nest when assembled as best seen in Figure 3. Y Y One method of assembly of the parts to form a complete container is as follows:

The outer cylinder I2 is forced downwardly p over the inner cylinder I3 and the upper portion, "that is to say, principally the shoulder 28 is conv tracted in diameter by the forcing together of upper end of the channel I3 is closed and lis disposed below the end I1. The lower end 2I of the channel I3 is closed and is disposed adjacent and above the end I8. i

The inner cylinder I3 includes the cylindrical side wall 22, the bottom wall 23, and the exposed side ywall portion or actuating member 24. The actuating member 24 includes the upper enlargement or shoulder `25 and a lower corresponding shoulder 26. In order to facilitate the rotation of these shoulders together with the parts connected thereto, these shoulders may be knurled in a well known manner. The inner cylinder is thus in the form of an open topped cup having the upper end 21. Slightly below the upper end 21 the inner cylinder I3 is provided withan expanded annular shoulder 28. The inner cylinder I3 is provided with'a spiral slot or channel 29 having upper and lower ends 33 and 3I respectively. The lower closed end 3| terminates slightly above the shoulder 25 while the upper end 30l terminates slightly below the shoulder 28.I The'upper end 3U of the spiral slot or channel 29)'is closed'except for a vertically Vdirected slot 32 which extends from the end 30 to the edge 21.

'lhe cosmetic carrier I4 is in the form of a hollow cup and is composed of suitable resilient material, preferably spring brass, having a cylindrical side wall 34 and a bottom wall 35. The cupA thus'opens upwardly, the upper edge of the cylindrical wall 34 being indicated by numeral 36.v The side wall 34 is provided with a V shaped orifice or cut out 31, thus leaving a resilient tongue or spring member 38 which is formed of 'the same material as and is integral with the side wall 34. The spring member 38 is of unusual configuration, best seen in Figures 4, 5, and `6 of the accompanying drawings and extends outwardly of the normal body of the cylinder 34 by` The bend 38 is along an axis parallel to and spaced from the longitudinal axis of the carrier I4. The outer end of the spring member is provided with an outwardly bent tab-like projection or lug 43, the lugr 4I! is forme-d by reason of the bend 4I which is along a line parallel to and spaced from the longitudinal axis of the carrier, thus the lug 40 is normally radially disposed with relation to the longitudinal axis of the carrier I4.

The'cosmetic stick 5I may be composed of any suitable material normally used for this purpose and' is usually in the form of a solid cylinder. The cosmetic stick 5I has a lower end which is placed in contact'with the upper surface of the bottom wall and hasan upper end 42. The internal, diameter of the carrier I4 is such as'to frictionally engage the outer cylindrical wall of Y the cosmetic stick 5I. The internal diameter of the inner cylinder I3 is slightly greater than the external diameter of the carrier I4. The internal diameter of the outer cylinder I2 is slightly thefopposite vertical sides of the slot 32 so that the outer cylinder I2 may be moved downwardly thereover. upper portion of the inner cylinder with the lug -in'the upper entrance to slot 32. In this position the outer surface of the spring member 3B will frictionally 'and resiliently engage the inner surfaceof the inner cylinder I3 adjacent thereto. The width of the slot 32 is normally slightly less than thertransverse thickness, that is to say, the

distance between thesurface v and the surface 4B on the lug 40. As the carrierv I4 is pushed downwardly, the lug 40 engages the sides of the slot 32 and temporarily forces them out sufficiently to allow the downward passage therebetween of the lug 43, When the lug 43 arrives at a level suiciently low to have the outer tab thereof engage the inner surface of the outer cylinder I2, the lug 40 willbe forced inwardly but by reason of the resilient nature of the spring member 38, this displacement of the lug 4D will be accompanied by no .harmful effects. Upon pushing the carrier I4 down farther it will emerge from the slot 32 and into the slot 29. .'If the outer` cylinder is in proper alignment with the inner cylinder, the outer end of the lug 40 -will also enter the spiral slot I3. Otherwise, it is merely necessary to rotate the outer cylinder I2 until the slots I3 and 29 intersect at the uppermost portion thereof, at which time the spring member 38 will force the lug 4B outwardly into the slot I9. The cosmetic stick 5I may now be inserted into the carrier I4, though, where desired,vthe cosmetic stick'EI may have been previously inserted into the carrier I4 before the same was articulately connected with the other parts. Y

y It may thus be seen that rotation of the sleeve or cylinder IZ'and/or rotation of the sleeveor cylinder I3 with relation to each other will result in the projection or retraction of the carrier I4 and the cosmetic stick 5I. By reason of the conf struction and conguration of the spring memthe bend 39 any desired braking action may be had so that a certain predetermined amount Vof torque upon either of the cylinders I2 or I3V with relation toV eachV otherwill be lrequired to cause the carrier to moveV longitudinally of the device. While the outer cylinder I2 and the inner cylinder I3 have been described as havingr oppositely pitched spiral slots as is well known in the art to which the present invention relates, obviously either of these slots may be made straight.

While it has been previously stated herein that the width of the slot 32V in the first embodiment of the inventionV is normallyslightly less than the transverse thickness, that is to say, the dis- Next the carrier is placed within theV carrier in the device initially, in an alternate construction, the width of the slot 32 may be equal to or slightly greater than the transverse thickness of the lug 40, as above defined. In such construction, the lug 40 will not require any appreciable amount of force in order to push the same through the slot- 32 to reach the slot 29. After the lug 4D has engaged not only the slot 29 but also the slot I9 which, as seen in Figure 1, has a closed upper end as indicated by numeral 20, this closed upper end of the slot I9 will prevent inadvertent removal of the cosmetic carrier since the lug 49 will be prevented from entering the slot 32 by the portion 20 of the slot I9.

Since all of the parts are each capable of being fabricated independently from all of the others and no machine forming or distorting operations are required at the time of assembly, both the cost of fabrication and assembly is reduced. It may be noted,l however, that by use of the integral lug 40, the need for punching the carrier I4 and providing the same with a riveted projection is" eliminated. Since the lug 40 is resiliently mounted, the same may shift radially of the device as the carrier is longitudinally shifted in either direction to accommodate slight Variations in the size of the parts so that the commercial tolerances required during the manufacturing operations may be so much greater.

By reason of the novel braking action obtained by the use of the spring member 38, accidental or indefinite moving of the carrier, either up or down, during use or. during the carrying -thereof is reduced to a minimum.

Turning now to the second embodiment of the invention illustrated in Figures '7 to 9 inclusive for the purpose of avoiding needless repetition, parts corresponding generally to those of the first embodiment are given singly primed reference characters.

The principal difference between the second embodiment and the first embodiment lies in the fact that instead of the cosmetic carrier I4be ing elevated by means of cooperating spiral slots or a spiral slot and a straight slot, the cosmetic carrier is elevated by a manual operation by elevating the actuating member 24" in a rectilinear direction along the straight slot 29". The ends 30 and 3| act as limits for the movement of the lug 40 longitudinally of the device I0.

In the second embodiment the distance between the sides of the slot 32' is not only less than the thickness of the lug 40', that is to say, between the surfaces 45' and 46' so that after being once installed, the lug 40 may not enter the slot 32' so that the end 3D of the slot 29" may serve as a suitable upper limit.

As previously described in connection with the first embodiment, the resilient tongue or spring member 38' engages the inner surface of the' cylindrical side wall 22' of the cylinder I3' and thereby acts as a brake to prevent undesirable longitudinal shifting of the cosmetic carrier I4 with relation to said cylinder.

It may be noted at this point, that in all of the constructions described the cosmetic carrier` I4 is of substantially identical construction so that the same may be interchangeably used in the different general types of device.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described for obvious modifications will occur to a person skilled in the art.

I claim:

1. A cosmetic container comprising, an outer cylinder having a first slot, an inner cylinder disposed within the outer cylinder and having a second slot, one of said slots being angularly disposed with relation to the other, a cosmetic carrier having an external diameter less than the internal diameter of the inner cylinder, said carrier being in the form of a hollow cup and composed of resilient material and having a cylindrical side wall and a bottom wall, said side wall being provided with a substantially vshaped cut-out thereby forming a spring member integral with said side wall, said spring member being outwardly bent along an axis parallel l to and spaced from the longitudinal axis of the carrier, said spring member extending outwardly of the normal body limits of the said side wall and adapted to resiliently frictionally engage the inner surface of the inner cylinder, the outer free end of the spring member being outwardly bent along a line parallel to and spaced from the longitudinal axis of the carrier, forming an outwardly bent tab-likek lug which is normally radially disposed with relation to the longitudinal f axis of the carrier, said lug penetrating the rst and second slots, whereby rotational displacement of one of said cylinders with relation to the .other will cause a displacement of said carrier longitudinally of the cosmetic container, said spring member acting to frictionally retain the carrier in displaced position thereof.

2. A cosmetic container comprising, an outer cylinder having a first helical slot angularly disposed with relation to the central longitudinal axis of said container, an inner cylinder disposed within the outer cylinder, said inner cylinder having a second helical slot angularly disposed with relation to the first slot, a cosmetic carrier of cup form having an external diameter less than the internal diameter of said inner cylinder,
