Another object of this invention is to provid novel cosmetic ejecting means that are simple and inexpensive and yet effective and dependable.

Another object of this invention is to provide a device of the character mentioned in which re placement supplies of cosmetic may be easily supplied to the individual cosmetic chambers without removing the container or the heads of the container. K

Another object of this invention is to provide a device of the character referred to in which the stems of the ejecting pistons are telescopically related in a novel manner to conserve space.

A further object of this invention is to provide a cosmetic applicator of the character referred to that is small and compact and shaped and proportioned to be conveniently handled and operated. Y

The various objects and features of my invention will be fully understood from the following detailed description of a typical preferred form andV application of the invention, throughout which description reference is made to the ac companying drawing, in which:

Fig. 1 is a side elevation of the improved 4cosmetic applicator of the present invention showing one of the brush covers inlongitudinal cross section. Fig. 2 is an enlarged fragmentary 1ongitudinal detailed sectional view of the device showing certain parts in elevation. Fig. 3 is an enlarged transverse detailed sectional View taken as indicated by Iline 3--3 on Fig. 2, and Fig. 4

is a longitudinal sectional view of one of the brush means.

The device provided by this invention may be said to comprise, generally, a body I9, two cosmetic reservoirs or containers I I arranged in the body ii] for independent turning, cosmetic applying means I2 on the containers I I, and means I3 for forcing or ejecting the cosmetic from the containers I I to the means I2.

The body I0 is an elongate tubular member that carries the two cosmetic containers I i The central longitudinal opening I4 of the body lil is provided at its opposite ends with sockets I5 of enlarged diameter. The sockets I5 are of equal depth and diameter and are cylindrical. An annular internal flange I6 is provided on the wall of the body opening I4 at the inner end of one of the sockets I5. The body Ill may be formed of any selected material and may be shaped, finished, -and ornamented, as desired. In the case illustrated the body I il has a cylindrical external surface and is provided midway between its ends with a series of rings or beads |68.

The containers I I are provided to contain supplies of the cosmetics. The cosmetic containers I I are hollow or tubular members having chambers or longitudinal openings Il which serve as reservoirs for the cosmetics. In accordance with the invention the containers II may be alike or identical and are arranged to project from the opposite ends of the body Iii. The inner portions of the containers II are shaped and proportioned to be rotatably received in the body sockets I5. Series of external annular beads I8 may be provided on the containers II to complement the body beads |63. The beads I8 form or provide shoulders I9 which oppose or abut the opposite ends of the body I. The outer portions of the containers II are formed to receive the applying means I2. The outer end parts of the containers II are rounded or tapered and openings 2i! of reduced diameter extend centrally through the reduced container parts to join the openings Il.

Novel means are provided to rotatably connect the containers II with the body l0. Annular grooves 2I are provided in the walls of the sockets I5 and annular grooves 22 are provided in the containers I I to register with the grooves 2i. The grooves 2l and 22 are flat-walled and are preferably proportioned to form or provide annular spaces of square or rectangular cross section. Split spring rings 23 are arranged in the pairs of registering grooves 2I and 22 to hold the containers II against longitudinal movement relative to the body IIJ. The spring rings 23 are square or rectangular in cross section to cooperate with the flat Walls of the grooves 2| and 22. The grooves 22 in the containers II are sufiiciently deep to fully receive the rings 23 when the rings are compressed, When assembling a container II in the body I9 a ring 23 is arranged in the groove 22 of the container and is compressed or contracted and the inner portion of the container is inserted in a body socket I5. When the container has reached its final position the ring 23 expands into the surrounding groove 2|. The groove 2| limits the expansion of the spring ring 23 and holds the spring ring partially contracted so that its inner portion cooperates with the groove 22 in the container II. It is preferred to connect the spring rings 23 with the containers I I to turn with the containers. Each spring ring 23 has an inturned end part 24 received in a radial socket Z5 in its respective container II. The engagement of the parts 24 in the sockets 25 holds the rings 23 against turning relative to the containers. It will be seen that the containers II connected with the body Iii by the spring rings 23 are free to be independently turned relative to the body I and yet are dependably held against longitudinal movement and against displacement from the body.

The cosmetic applying means I2 are provided to facilitate the application of the cosmetics. An applying means I2 is provided on the outer end of each container I I. In the preferred form of the invention the means I2 are in the nature of brush means and the two means I2 are identical.

Each applying means I2 includes a tubular brush carrier 2S. The carriers 26 have threaded cylindrical inner parts 21 adapted to be threaded in the openings 2t! of the containers II. 'The outer end parts of the carriers 26 are tapered to complement the tapered end portions of the containers I I. In the case illustrated the tapered outer parts of the carriers 23 have series of annular beads 28 similar to the beads Ia and I8. The central longitudinal openings 29 of the tubular carriers 26 are longitudinally tapered throughout their major portions. In the preferred construction the inner end parts of the openings 29 are cylindrical and the openings taper from these cylindrical parts to the forward ends of the carriers 26.

The brush means II further include brush tufts 3D set or secured in the openings 29 of the carriers 2%. The tufts 3) comprise groups of bristles arranged longitudinally in the openings 29 to project beyond the outer ends of the carriers 26. The inner portions of the brush bristles are fixed in the tapered openings 2S. I prefer to set the inner parts of the bristles in a mixture of wax and rosin or a mixture of wax and synthetic wax that is sufficiently hard to dependably retain the bristles and yet will not crack or flake away. The wax and rosin mixture employed to set the brush tufts 39 is unaffected by the cosmetics and will not lose or free hard particles that may become mixed with the cosmetics.

The applying means I2 further include elongate shanks or tubes 3i arranged longitudinally in the set inner parts of the brush tufts 30. The tubes 3| are considerably smaller in diameter than the openings 29 to leave annular spaces for the set brush bristles. Openings 432 of large diameter extend through thetubes 3| to conduct the cosmetics from the openings I'I to the forward portions of the brush tufts 30. It is preferred to relate the parts so that the forward ends of the tubes 3| are substantially ush with the forward ends of the carriers 26. The forward end parts of the tubes 3| are preferably tapered. I prefer to form the tubes 3| of metal and the forward parts of the tubes may be reduced or tapered by a spinning operation. Enlargements or anges 33 are provided on the rear or inner ends of the tubes 3|. The fianges 33 are pressed or force-fitted in the cylindrical inner parts of the openings 29. The flanges 33 thus secured in the openings 29 retain the tubes 3| in place and assist in securing the brush tufts 39 in the carriers.

In assembling an applying means I2 the brush tuft 3i) is first set in the opening 29 and a heated pointedtool is then thrust through the wax and rosin mixture in which the bristles are set. The tube 3| is then arranged in the opening formed by ,the heated tool. It is to be noted that the brush tufts 30 are dependably retained byA the wax and rosin mixture and by the wedging action of the tapered openings 29. The tubes 3| arranged longitudinally in the inner parts of the tufts 39 confine and assist in retaining the brush tufts. The beads 28 form effective grips by means of which the carriers 23 may be unthreaded from the openings 29. rfhus the means I2 may be removed from the carriers I I to allow the replenishing of the cosmetic supplies of the containers and to permit the replacement of the vbrush means I2.

Removable caps 34 are applied to the containers I I to enclose and protect the brush tufts 30. The caps 34 are formed to be removably pressed on the projecting portions of the carriers II. The sockets or openings 35 in the caps 34 receive the brush tufts 3o with clearance so that the caps do not distort the brush tufts. When the caps 34 are in place they prevent the cosmetics in the brush tufts 39 from soiling the clothing, hands, etc. The exteriors of the caps 34 may be suitably shaped, for example, they may be stepped or graduated in diameter, vas illustrated.

The -ejecting means I3 are separately or independently operable to force the cosmetics from the openings I'I into the brush tufts 30. There is an ejecting means I3 for each container The ejecting means I3 each include a piston or plunger 3S operable in an opening 4 I1. The plungers 39 have annular peripheral grooves 31 and split sealing elements 38 of rubber, leather, or the like, are set in the grooves 3l to slidably seal with the walls of the openings II. The grooves '31 are of substantial depth to dependably retain'the sealing elements 38. -One plunger 36 is secured to the end of a tubular stern 39 while the other plunger 33 is fixed to the end of a stem 40 that may be solid. The stems 39 and 40 are telescopically arr-anged, that is, the stem 4U is received in the stem 39. As illustrated in Fig. 2 the stem 40 is received in the stem 39 with substantial clearance and does not cooperate with the stem. 39. The tubular stem 39 has a thread 4I vmating with a thread on the wall of the body opening I4. The thread 4I may extend throughout the length of the stem 39. The stem 40 has a thread 42 mating with a thread on the internal surface of the flange I6.

Means are provided to prevent relative rotation between the containers I I and vtheir respective plungers 3S whereby rotation of a container I I relative to the body 'I9 threads Vor advances its plungers 36.' These means comprise flat surfaces 43 on the walls of the openings l1. In practice there may be two diametrically opposite and substantially parallel surfaces 43 on the wall of each opening I1. The plungers 3B have at peripheral surfaces 44 slidably engaging the surfaces 43. The engagement of the surfaces -44 with the surfaces 43 holds the plungers 36 and their respective stems 39 and 40 against rotation relative to the related containers Il so that turning of the containers relative to the body l results in threading or advancement of the stems and plungers. The sealing elements 38 of the plungers 36 are cut away or provided with flat partsfor sealing with the surfaces 43.

In the use or operation of the device of the invention the openings l'l may be loaded or provided with cosmetics before the carriers 26 are threaded in the openings 20. The plungers 3E are, of course, initially retracted. The openings I1 of the containers Il may be provided with cosmetics of diierent kinds or of diierent shades or textures. The caps 34 are normally in place so that the device may be carried in a hand bag or the like without injuring the brush tufts 30 and without soiling the clothing, etc. When it is desired to apply one of the cosmetics the cap 34 is removed from one end of the device and the body I0 and the selected container H are turned one relative to the other. The body I0 and the container I l may be conveniently grasped for this operation. Turning of the container Il relative to the body I0 results in operation or advancement of the related plunger 36 and the plunger moving outwardly in the opening I1 ejects a portion of the cosmetic from the opening to the brush tuft 30. The cosmetic thus supplied to the brush tuft 30 may be applied by means of the brush tuft. The body Il! and the associated containers Il constitute an effective handle for the brush tutt to facilitate the application of the cosmetic. Following the -application of the cosmetic the cap 34 is re-applied to the container l I. The supplies of the cosmetics may be readily replenished by merely retracting the plungers 36 to their initial positions and removing the carriers 26 to allow the cosmetics to be introduced to the openings I1. The carriers 26 are readily threaded from the openings 20. The device is small and compact and is adapted to contain adequate supplies of cosmetics.

Having described only a typical preferred form and application of my invention, I do not wish to be limited or restricted to the specic details herein set forth, but wish to reserve to myself any variations or modifications that may appear to those skilled in the 4art or fall Within the scope of the following claim.

Having described my invention, I claim:

In a cosmetic applicator, a body adapted to Abe employed as a handle, a container for cosmetics entered in an end of the body to extend therefrom, a brush on the container for applying the cosmetics received therefrom, means retaining the container in the body for rotation and holding the container against longitudinal movement relative to the body, a plunger operable in the container, a stem on the plunger having threaded cooperation with the body, and means holding the stern against turning relative to the container whereby turning of the container relative to the body causes ejection of the cosmetics to the brush.

CHARLES A. MUREAU.
