3 Claims.

This invention relates to a device for containing and applying cosmetics such as paste lip rouges, mascara, etc., and it is a general object of the invention toprovide a practical, effective device of this character that is extremely simple and inexpensive of manufacture.

Another object of this invention is to provide a cosmetic applicator embodying a simple, inexpensive, one-piece body forming a container for a supply of a cosmetic and carryinga means for applying the cosmetic and a means for ejecting the cosmetic to the applying means.

Another object of this invention is to provide a device of the character mentioned in which the ejecting means embodies a minimum number of simple parts and does'not necessitate the cutting of threads or the accurate machining of the parts.

Another object of this invention is to provide a device of the character mentioned in which the ejecting means is easily and quickly operated by merely pushing an operating part on the ejecting plunger.

Another object of this invention is to provide a device of the character mentioned embodyin a novel and very effective means for yieldingly or releasably holding the ejecting plunger against movement, which means automatically releases when the plunger is pushed to eject the cosmetic.

A further object of this invention is to provide a novel and simplified brush means for a device of the character referred to that is simple and compact.

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

Fig. 1 is a side elevation of the improved device of the invention. Fig. 2 is an enlarged fragmentary longitudinal detailed sectionalview of the device showing certain parts in elevation and indicating the normal position of the cap in broken lines. Fig. 3isa longitudinal detailed sectional view of the brush means removed from the body. Fig. 4 is a side elevation'of the retaming element or plug. Fig. 5 is a longitudinal cross section of the sealing element of the plunger. Fig. 6 is a longitudinal detailed sectional view of the plunger. Fig. '7 is an end view of the plunger-holding ring,and'Fig. 8 is a longitudinal detailed sectional view'of another form of brush means.

The device of the invention may be said-to comprise, generally, a body It) forcontaining a supply of a cosmetic, cosmetic applying means I l projecting-from an end of the body l0, and ejecting means [2 for ejecting the cosmetic from the body II] to the applying means H.

The body I0 is an elongate hollow or tubular member having a central longitudinal opening which constitutes a chamber l3 for the cosmetic. It is a feature of the invention that the body It! is a simple one-piece member adapted to be formed of any suitable material suchas one of the so-called plastics. The exterior of the body l0 may be shaped and finished as desired. In the case illustrated the body [9 has a plain, cylindrical exterior. The cosmetic chamber I3 extends to the rear end of the body -l0to receive a part of the ejecting means l2, as will be later described. The forward portion l4 of the body Ill isreduced in diameter and theforward extremity of the body is curved or tapered inwardly. A socket I5 of reduced diameter is provided in the forward body portion l4 and a reduced opening [6 passes through the forward wall of the body. It is to be noted that the body' l9 does not embody joints or connections anddoes not require the cutting of threads.

The applying means i i is provided to facilitate the application of the cosmetic. The means II is mounted in the forward portion of the body Ill andis preferably in the form of a brush-means.

In Figs. 1 to '7, inclusive, of the drawings the brush means ll comprises a tubular shell IT, a brush tuft l8 and a tube [9 in the tuft I8.

The shell ll is a tapered or frusto-conical member and is positioned in the body socket IS.

The shell I7 is arranged to have its'small end facing forwardly. The internal diameter of the small end of the shell i1 is substantially the same as the diameter of the opening l6.

of good quality arranged longitudinally in the shell H. The inner portions of the brush bristles are set in a body of wax and rosin or wax and synthetic wax in the tapered shell ii. The bristles forming'the tuft 13 are sufficiently long to project forwardly through the opening [6 andto protrude a substantial distance from the forward extremity of the body iii. The forward end of the shell I! may be spaced rearwardly from the front wall of the body N! as the opening l6 serves to support and stabilize the outer projecting portion of the brush tuft I8.

The tube [9 extends forwardly in the brush tuft Whom the inner end of the tuft. The lon- The brush'tuft It comprises a multiplicity of bristles gitudinal opening 20 of the tube I 9 is large in diameter to readily conduct the cosmetic forwardly from the chamber I3 to the interior of the bush tuft I8. The forward portion of the tube I9 may be tapered or reduced to concentrate the cosmetic discharge. The tube I9 discharges within the brush tuft |8 at a point between the ends of the tuft. In the preferred arrangement the foward discharge end of the tube I9 is substantially flush with the forward extremity of the body III. A flange 2| is provided on the inner end of the tube I9. The flange 2| is pressed or force-fitted in the socket |5 to secure the brush means II in the body In. In the embodiment of the invention being described the flange 2| is solid and the shell I! and the inner end of the brush tuft I8 engage against the forward face of the flange. In the alternative form of brush means illustrated in Fig. 8 of the drawings the flange 2| of the tube I9 is cup-shaped, having a radial end wall 22 and a circular axial wall 23 facing or projecting forwardly. In this case the inner portion of the shell I! and the inner part of the brush tuft I8 are received within the wall 23 of the flange 2 l This serves to support and centralize the shell I! and the brush tuft I8 and reduces the overall length of the brush means II. The axial wall 23 of the flange 2| is force fitted in the socket I5 to secure the brush means in the body III. In both forms of applying means or brush means the set or embedded inner portion of the brush tuft I8 is dependably retained in the conical shell IT. The wall of th conical shell I! has a wedging action and firmly holds the brush tuft.

A cap 24 is provided to cover and protect the protruding portion of the brush tuft I8. The cap 24 may be removably slid on the reduced forward portion I4 of the body I0 and the major portion of the cap may be of the same shape and diameter as the body ID. The forward portion of the cap 24 is tapered or reduced in diameter. The cap 24 is easily removable from the body II] to expose the brush tuft I8 for use.

The ejecting means I2 is operable to eject portions of the cosmetic from the chamber I3 to the interior of the brush tuft I8. In accordance with the invention the ejecting means I2 is in the nature of a sliding plunger means. The means I2 includes a plunger 25 operable in the chamber I3. The plunger 25 extends from the rear end of the chamber I3 to protrude from the body I0. In practice the plunger 25 may be a simple, generally cylindrical member formed of a plastic or the like. It is preferred to make the plunger 25 hollow or tubular to reduce its weight and cost. In the case illustrated the plunger 25 has a central longitudinal opening 26.

Means is provided on the forward end of the plunger 25 for slidably sealing with the wall of the chamber I3. This means includes an annular washer or sealing element 21 seated against the forward end of the plunger 25 and sealing with the wall of the chamber I3. A plug 28 is pressed or force-fitted in the forward end of the opening 26 and has a head 29 engaging against the forward face of the sealing element 21 to hold the element in place and to close the forward end of the opening 26. It will be observed that the sealing element 21 is secured to the plunger 25 without resorting to the use of screw threads or other expensive securing means. The head 29 of the plug 28 is preferably proportioned to clear the wall of the chamber I3. An annular rearwardly facing shoulder 30 occurs on the wall of the chamber I3 where the chamber joins the socket I5 and the head 29 is adapted to engage the shoulder 39 to limit the forward movement of the plunger 25. The plunger 25 may be pushed or moved forwardly relative to the body II] to eject a portion of the cosmetic through the opening 20 into the brush tuft I8.

The invention provides simple yet very effective means for normally releasably holding the plunger 25 against longitudinal movement. This means comprises a spring ring 3| engaging about the plunger 25 at the rear end of the body I0. The spring ring 3| is proportioned to grip the plunger 25 through its resiliency and its cooperation with the end of the body I9 normally prevents inward movement of the plunger relative to the body. The chamber I 3 is filled with the cosmetic and atmospheric pressure resists outward movement of the plunger 25. When the plunger 25 is intentionally pushed or moved inwardly the spring ring 3| yields or merely frictionally resists the movement. The spring ring 3| is such that the plunger 25 may be effectively operated to discharge required quantities of the cosmetic into the brush tuft I8 by merely applying short quick taps or thrusts to the rear end of the plunger.

In the use or operation of the device the chamber I3 initially contains a supply of the cosmetic and the cap 24 normally encloses and protects the brush tuft I8. The device may be carried in a pocketbook or in a pocket without danger of loss of the cosmetic and without soiling the clothing. When it is desired to use the device the cap 24 is removed from the body I0 and the plunger 25 is moved forwardly relative to the body Ill. The plunger may be operated by grasping the body I0 and tapping or thrusting the plunger 25 to move it the required distance. As above described the spring ring 3| normally holds the plunger against inward movement but yields to allow this movement when the plunger is intentionally operated. Upon forward movement of the plunger 25 a quantity of the cosmetic is forced through the opening 20 into the brush tuft I8. The brush tuft I8 may be conveniently employed to apply the cosmetic. The body I0 and the plunger 25 constitute a handle for the brush tuft I8. After use the cap 24 is replaced. When it is desired to replenish the supply of cosmetic the plunger 25 is merely withdrawn from the body I 0 and a supply of the cosmetic in the'form of a cartridge or in any other form is introduced into the chamber I3. The plunger 25 carrying the ring 33 is then replaced in the chamber I3.

Having described only typical preferred forms and applications of the invention, I do not wish to be limited or restricted to the specific 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.
