2 Claims.

This invention relates to cosmetic applying devices and relates more particularly to devices for containing and applying paste lip rouge, mascara, etc. A general object of this invention is to provide a practical and effective cosmetic applicatorv of this nature.

Another object of this invention is to provide a cosmetic applicator embodying a container for a supply of the cosmetic, a novel brush means for applying the cosmetic and an improved ejecting means for ejecting the cosmetic into the brush means.

Another object of this invention is to provide a device of the character mentioned in which a single one-piece body forms the cosmetic container, the head for supporting the brush means and the housing and support for the ejecting means.

Another object of this invention is to provide a cosmetic applying device in which a replacement supply of the cosmetic may be introduced into the body without disturbing the applying means or brush means. In the applicator of the present invention the cosmetic is supplied through the end of the body opposite the brush means so that there is no necessity for removing or disturbing the brush means.

Another object of the invention is to provide a novel brush means that is simple and inexpensive to manufacture and that may be readily secured in the applicator body without resorting to the use of screw threads.

A further object of this invention is to provide a cosmetic applicator of the character mentioned in which the ejecting means embodies a minimum number of simple', inexpensive parts and is conveniently operable by merely turning a knob at the outer end of the body.

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

Fig. 1 is a side elevation of the improved cosmetic applicator of the invention. Fig. 2 is a view similar to Fig. 1 with the cover or cap removed. Fig. 3 is an enlarged central longitudinal detailed sectional view of the applicator. Fig. 4 is a transverse detailed sectional View taken as indicated by line 4 6 on Fig. 3, and Fig. 5 is an enlarged side elevation of the brush means removed from the body.

The cosmetic applicator of the present invention may be said to comprise, generally, a body n I0 forming a container for a supply of the cosmetic C, applying means II projecting from the forward end of the body I0 for applying the cosmetic C, and means I2 for forcing or ejecting the cosmetic C from the body I@ to the applying means II.

The body I0 is a hollow or tubular member that serves as a container for the cosmetic C and that carries the other elements of the device. In the preferred construction the body III is an elongate one-piece or integral member. In practice the body I0 may be formed of any suitable or selected material, for example, it may be formed of metal or of any of the so-called plastics. A central longitudinal opening I3 of substantially uniform diameter enters the body I0 from its outer or rear end. The opening I3 forms the cosmetic reservoir or chamber. The forward portion III of the body II! is reduced in diameter to provide an external annular shoulder I5v and this reduced body portion I4 tapers or rounds inwardly at the forward extremity of the body. A socket I6 of somewhat reduced diameter extends forwardly in the body portion I4 and an opening I'I of still smaller diameter continues forwardly from the socket I1 to the forward end of the body. A rearwardly facing shoulder I8 occurs on the inner surface of the body I0 where the socket I6 joins the opening I3. A removable cover or cap I9 is applied to the reduced forward portion E4 of the body I0 to enclose and protect the applying means II as will be further described. The inner part of the cap I 9 may be flush with the external surface of the body I0 while the forward portion of the cap may be stepped or graduated as illustrated. It is to be observed that the body` I0 is of simple, inexpensive construction.

The applying means II is provided to facilitate the application of the cosmetic C and is particularly useful in the application of lip rouge, mascara, and the like. In the preferred form of the invention the means II is in the nature of a brush means particularly adapted for the handling of paste rouges, etc. The means II is carried in the reduced forward portion I4 of the body I I) and includes a tubular shell 20 preferably formed of metal. The shell 20 is tapered or frusto-conical and is received fu the socket I6 with suitable clearance. The forward end of the shell 20 is adjacent the inner end of the opening I'I and the internal diameter of metio discharge.

bristles set in the shell 20. The bristles constituting the brush 2| are preferably soft and flne and of substantial length. The inner portion of the brush 2| is secured in the conical shell 20 by setting the brush bristles in a body of wax and rosin. I have found that a mixture of wax and rosin or synthetic wax in suitable proportions is unaffected by the cosmetics and does not flake away or produce hard particles that may become mixed with the cosmetics. The bristles set or embedded in the wax and rosin or synthetic wax mixture in the tapering shell are securely held in place and forward pressures against the brush tend to tighten the brush in the shell. The bristles constituting the brush 2| are suiliciently long to extend through the opening |1 and project a substantial distance from the forward end of the body IU.' The wall of the opening I1 supports and confines the intermediate portion of the brush 2| and centralizes the projecting part of the brush 2Ir It will be observed that the active outer portion of the brush that receives the cosmetic is out of contact with the shell 20 and all other metal parts.

The means I I further includes a shank or tube 22 extending centrally through the brush 2|. The tube 22 has an enlarged part or flange 23 tightly tting the socket I6 and the forward portion of the tube 22 is tapered. The inner end of the brush 2| and the inner end of the shell 2|) may engage against the forward face of the flange 23. The longitudinal opening 24 of the tube 23 communicates with the cosmetic opening I3 and discharges into the brush 2| at the forward end of the device. In the preferred construction the forward end of the tube 22 is substantially flush with or slightly inset from the forward extremity of the body I0. The longitudi nal opening 24 of the tube 22 is large in diameter to assure a free flow of the cosmetic. However, the forward end portion of the tube is tapered and reduced in diameter to concentrate the cos- The outer portion of the tube 22 may be reduced or tapered by a spinning operation. In constructing the brush means or applying means the brush 2| is first secured or set in the tapering inner part of the shell 20 and a suitable pointed tool is heated and forced through the wax and rosin mixture in which the brush is set. The opening thus formed is adapted to receive the tube 22 and the tube is immediately arranged in this opening. It is to be noted that the brush 2| is rather closely confined between the tube 22 and the forward portion of the shell 20 so that the brush 2| is dependably centralized and sustained. 'Ihe flange 23 tightly fitting the socket IB secures the means |I in the body. It will be observed that the tube 22 operates to deliver the cosmetic from the body opening I3 to the interior of the brush 2| at thel forward extremity of the body I0 to be immediately available for application.

The ejecting means I2 is provided to eject or force the cosmetic C from the body opening I3 to the interior of the brush 2|. The means I2 includes a plunger 25 on the forward end of a threaded stem 2B. The stem 26 is of substantial length and is threaded from adjacent the plunger 25 to its rear end.- An annular groove 21 is provided in the plunger 25 and a washer or sealing element 2B of leather, rubber, or the like, is sprung or set into the groove 21. The sealing element 28 may be split to facilitate its insertion in the groove 21 and the groove is of subincludes a brush tuft or brush 2| made up of stantial depth to dependably retain the sealing element. The peripheral part of the sealing element 28 slidably seals with the wall of the body opening |3. A longitudinal key or flat tangential surface 29 is provided on the wall of the body opening I3. The surface 29 preferably extends from the rear extremity of the body I0 to the shoulder I8. A at tangential surface 30 is formed on the periphery of the plunger 25 and slidably cooperates with the surface 29. The sealing element 28 is suitably shaped to cooperate with the surface 29. The cooperation of the surface 29 and the surface 30 holds the plunger 25 and the stem 26 against rotation. The shoulder I8 limits the forward movement of the plunger 25.

The ejecting means I2 further includes a retainer or cap 3|. Rather coarse threads 32 removably secure the cap 3| on the rear portion of the body I0. The cap 3| is provided with a central longitudinal opening 33. An operating knob 34 is disposed at the outer end of the cap 3| and has a socket 35 aligned with the opening 33. The knob 34 is shaped and formed for convenient operation. In the case illustrated the knob 34 is tapered and its periphery is provided with spaced grooves 36. The knob 34 rides or bears on the outer surface of the cap 3|. A tube 31 is secured to the knob 34. In practice the tube 31 has a reduced roughened or knurlecl part 4|) pressed or force-fitted in the socket 35. The tube 31 has an annular shoulder 4| engageable with the inner or forward surface of the cap 3|. The cooperation of the knob 34 with the outer surface of the cap and the cooperation of the shoulder 4| with the inner surface of the cap prevent longitudinal movement of the knob and tube 31. The tube 31 is of substantial length and extends forwardly in the body I0 to receive the plunger stem 26. The major portion of the tube 31 receives the stem 26 with substantial clearance. The forward part 38 of the tube 31 is reduced in diameter and has an internal thread mating with the thread of the stem 25. The construction just described promotes the economical manufacture of the means |2 as it makes it unnecessary to form a long thread in the tube 31. It will be seen that turning of the knob 34 results in threading or longitudinal movement of the stem 26 and the plunger 25.

In the use or operation of the device of the invention the opening |3 normally contains a supply of the cosmetic C and the cap I9 is normally in position on the body portion I4 where it covers and protects the brush 2|. When it is desired to employ the device the cap I9 is removed and the operating knob 34 is turned. This turning or rotation of the knob 34 results in forward movement of the stern 26 and plunger 25. Ihe plunger 25 moving forwardly in the body opening |3 ejects or forces the cosmetic through the opening 24 into the brush 2|. The cosmetic thus supplied to the brush may then be applied. The body I0 of course constitutes a handle for the brush means II and the brush 2| being formed of soft, fine bristles may be employed to effectively apply the cosmetic. After use the cap I9 may be replaced so that the device may be carried without soiling the hands, clothing, etc. 'Ihe brush 2| is effectively protected by the Cap i9.

After repeated use the supply of cosmetic C may become exhausted and it may be desired to replenish the supply. To accomplish this the cap 32 is rotated with respect to the body I0 to unthread it from the body. When the cap 32 is free from the body I the assembly of the cap, the knob 34,v tube 3l, plunger 25, etc., is withdrawn from the body. A replacement supply of the cosmetic C in the form of a cartridge or in any other form is then inserted in the opening I3 and the. cap 32 is re-applied to the body l0 to condition the ejecting means I2 for operation.

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 art or fall within the scope -of the following claims.
