Application July 28, 1941, Serial No. 404,328

1 Claim. (01. 15-137) This invention relates to improvements in means for dispensing plastic materials, and more particularly to apparatus for applying to curved surfaces cosmetics or other pastes, creams, or emulsions of substantial viscosity. More specifically, the invention contemplates a cosmetic applicator whereby rouge or similar plastic material may be applied to predetermined portions of the human lip in such manner that the edges of the area of application are sharply defined.

Ordinarily lip rouge is sold in the form of plastic sticks or pencils to be rubbed against the lips. After application, the finger is used to distribute the cosmetic and to wipe off the excess thereof. This procedure is wasteful and unaesthetic, and does not give the user sufficient control of the pattern to be formed upon the lips.

Various devices for facilitating the application of lip rouge heretofore have been suggested. None of these, however, has been adapted to apply a thin film of the cosmetic at a single stroke to the entire curved contour of the lips. Nor have the devices of the prior art been designed or constructed to control the width and sharply to define the margins of the area being coated, nor to remove excess cosmetic from regions which it is desired not to coat.

It is an object of the present invention to provide a lip rouge applicator having a resilient nozzle portion which terminates in a narrow, concave end region having a pair of resilient deformable protuberances thereon and a narrow elongated slot extending lengthwise along the concavity of said end region from one of said protuberances to the other.

Another object is to provide a device adapted to apply a plastic solid to the surface of a torus in a band of definite width and having sharply defined margins.

Another object is to provide a device of the class described and having a narrow slot therein adapted to form a plastic solid into a thin ribbon, in combination with resilient deformable prongs at each end of said slot and adapted to confine said plastic solid to a sharply defined area upon a yielding curved surface to which said solid is being applied.

Another object is to provide a cosmetic applicator having a narrow slot through which a cosmetic paste may be forced, and a flattened portion on the feeding means adapted to facilitate uniform feeding of said paste through said slot by churning said paste during the feeding operation.

Another object is to provide a refillable cosmetic applicator adapted to receive a cosmetic paste in stick form and controllably to discharge said paste in the form of a thin ribbon.

Another object is to provide an article of the class described and adapted to remove the base of the used refill cartridge when the applicator is opened in order to refill the same.

Another object is to provide an applicator having a threaded feed disk which engages with the wall of the container so as to prevent leakage of the paste by reaction backwards past said feed disk.

Another object is to provide a cosmetic applicator the parts of which are designed for con- Venience in manufacture and assembly.

Further objects are to provide apparatus of maximum simplicity, economy, ease of use, and safety.

The foregoing and such other objects, advantages, and capabilities as may appear herein or be pointed out as this description proceeds, or as are inherent in the present invention, are illustrated in the accompanying drawings, in which:

Figure 12 is a fragmentary view in central vertical section and illustrates a modified construction of feed mechanism adapted to be employed in the device illustrated in Figure 7.

Like reference characters are used to designate similar parts in the drawings and in the description of the invention which follows.

My improved cosmetic applicator comprises a body portion adapted to enclose the cosmetic, a nozzle portion for applying the cosmetic, and

knob I2, which is rotatably fixed thereto. Fixed to said knob I2 and extending into the tube I substantially the entire length thereof is the.

blade I3. Slidably mounted upon the blade I3 is a threaded slotted washer I4, adapted to engage the threaded tube I. Thus rotation of the feed k'nob I2 will cause the blade I3 to churn the contents of the applicator and simultaneously will produce translation of the feed disk I4 within the tube I so as to eject a portion of the churned-up mass through the nozzle 2. Said churning action breaks up any lumps, kneads and softens the mass, and facilitates easy, uniform feeding of the cosmetic through the nozzle.

If desired, the region of the tube I immediately below the nozzle neck 4 may be unthreaded, as is shown at I6 in Figure 1. This arrangement permits the feed washer I4 to be rotated freely while in contact with the nozzle neck 4, and thus eliminates risk of breaking the feed blade I3 by turning knob I2 while rotation of the washer I4 is impeded.

The end of the tube I opposite the knob I2 bears the nozzle 2. Said nozzle is deformable and resilient, being fabricated of soft rubber or other material having the desired properties. As is shown in Figures 1, 2, 3, and 4, said nozzle comprises a more or less frusto-pyramidal head portion 3, and a neck portion 4 adapted to be attached to the tube I.- If desired, said neck portion may be threaded for this purpose. The tip of said head portion 3 presents a concave appearance and terminates in a pair of spaced

protuberances

5, 5 and an elongated narrow arcuate strip therebetween. Said arcuate strip is divided into lips II, II by .the slot I which extends lengthwise thereof and communicates with the interior of the nozzle. A suitable cover 9 is provided to promay be seated against the end of said tube. The

terminal region of the tube preferably is unthreaded and adapted to receive a portion of the knob I2, and the latter may be provided with an annular groove I5 into which the end of the tube I may be pinched in order to fasten the feed mechanism to the tube I. Thereafter, the tube I is filled with lip rouge or other cosmetic. If desired, the tip of the blade I3 may be pointed or sharpened to facilitate forcing a paste-like material into the applicator. After the applicator has been charged, the nozzle 2 is screwed into place, and the cover 9 is placed thereover.

In applying rouge or other cosmetic to the lips, the applicator illustrated in Figure l is employed in the following manner: The cap 9 is removed, and the thumb knob I2 is turned until a, small quantity of the rouge protrudes through the slot I. The nozzle 2 is then rubbed along the lip with the concave tip thereof nicely matching ,to the bottom of the tube I, removing the nozzle 2 and refilling the tube I. The nozzle is then replaced, and the device is ready for further use.

In the modification of the invention illustrated in Figures 7-1-0 inclusive, the body portion I 8 has an inwardly flanged annular rim I9 at one end, and an internal thread 20 at the other end. The nozzle 8 has an annular groove 22 in the neck 2I thereof, whereby said nozzle may be retained in said body portion by engagement of the flange I9 in the groove 22, as is shown in Figure '7.

As is more particularly shown in Figure 8, said nozzle 8 is somewhat similar to the nozzle shown in Figures 1-4 inclusive, but its tip is less concave. The slot I does not extend the entire length of the arcuate end strip, and the

unslotted portions

39, 39 subserve the same functions as the

protuberances

5, 5 on the modification shown in Figures 14 inclusive.

The threaded end of the tube I8 is adapted to receive the perforated screw cap 23. Through the perforation in said cap passes the neck 24 of the feed knob 25. Said neck 24 is provided with an annular slot 26, into which is fitted the horseshoe washer 21, thus retaining the feed knob 25 in the screw cap 23 while allowing free rotation of the former with respect to the latter.

Figure 12 illustrates an alternative construction, in which the feed knob 35 is provided with one or

more protuberances

36, 36 adjacent the base of the screw cap 31, and the base of said screw cap is provided with one or

more recesses

38, 38. A C-shaped flat spring 34 which urges the base of the feed knob toward the base of the screw cap is substituted for the horseshoe washer. As the feed knob 35 is rotated, the

protuberances

36, 36 periodically will fit into the

recesses

38, 38 and permit the

members

35 and 31 audibly to click together. Said clicking action also can be felt through the feed knob, and assists the user in controlling the feeding operation.

Extending axially from the feed knob 25 (Figures '7 and 9) or 35 (Figure 12) is the feed screw 28, which terminates in the spatulate element 29. Said element 23 is adapted to scrape the interior of the nozzle 8 and to churn the cosmetic 3I therein when the feed knob 25 is turned.

On the feed screw 28 is the piston 30, which is internally threaded so that rotation of the screw 28 with respect to the piston 30 will cause the latter to be translated along the axis of the former. Preferably, the member 28 is a left handed screw, so that clockwise rotation of the feed knob will advance the piston 30 toward the nozzle,

In order to prevent rotation of the piston 30 in the tube I8, said piston may be provided with one or

more ears

32, 32, and said tube may be provided with guide slots 33, 33 (Figure 10) longitudinally disposed in said tube and adapted to receive said ears. Alternatively, one or more ribs may protrude longitudinally along the interior of tube I8, and the piston 30 may be provided with a notch or notches to accommodate said rib or ribs.

Applicators constructed according to Figures '7 or 12 may be charged by removing the

screw cap

23 or 31 and the feed mechanism attached thereto, and inserting a stick of cosmetic into the tube [8. The piston 30 is screwed down to the neck of the feed knob, .the feed screw 28 is forced into the cosmetic, the screw cap is screwed into the tube l8, and the applicator is ready for use.

If desired, the cosmetic may be in the form of a cartridge mounted upon a metallic or'plastic base, such as the base ll shown in Figures 7 and 11. Said cartridge base II is provided with an aperture 40 through which the agitator 29 and the feed screw 28 may pass in order to assume the relative positions shown in Figure 7. The applicator is charged with a cartridge refill in the same manner as above described.

When the refill has been consumed, the screw cap is unscrewed and the feed mechanism is pulled out of the applicator tube. The agitator 29 ordinarily will engage the cartridge base II and pull the latter out of the applicator. The base II. is then removed from the feed mechanism and discarded. If the agitator 29 passes through the aperture 40 instead of engaging the base ll, said agitator is reinserted, the feed knob is given a quarter turn, and the base II is withdrawn.

From the foregoing it will be apparent that my improved applicator is composed of a few simple parts which may be assembled with great ease, and that it permits the application of cosmetics to the person with a greater degree of control and economy than has hithertofore been possible.

While I have illustrated my invention by describing particular embodiments thereof, it will be apparent to those skilled in'the art that numerous modifications and variations therefrom may be made without departing from the scope of my invention.

I claim:

A device of the kind described for applying a plastic cosmetic to the human lip, comprising a container, a nozzle for applicative purposes, and controllable means for feeding cosmetic contained in said container through said nozzle, said nozzle consisting of a portion connecting with the interior of said container and a somewhat fruitcpyramidal head portion terminating in a pair of deformable, resilient, narrow concave lips defining a narrow slit therebetween and having a deformable resilient protuberance at each end thereof for confining said cosmetic to a sharply defined predetermined region of the human lip.
