Patented Apr. 3, 1934 UNITED STATES ROUGE APPIJCATOR George A. Gleason, Chicago, Ill. Application November 15, 1933, Serial No. 698,115

3 Claims.

This invention relates to cosmestic appliances, and particularly to means for carrying and applying face cosmetics of a plastic or pasty nature, and has particular reference to rouge applicators oi the general type shown in my Patent N 0. 1,919,887

issued July '25, 1933.

The main objects of this invention are to provide an improved construction for the operating mechanism of rouge applicators of the type shown in said patent to the end of simplifying the operation thereof, affording greater security against leakage of contents, simplifying the refilling operation, and extending the useful life thereof.

A specific embodiment of this invention is illustrated in the accompanying drawing, in which:

Figure 1 is a perspective view of the applicator with the nozzle cap removed.

Fig. 2 is an enlarged longitudinal section of the applicator showing details of the operating mech- J anism and showing the nozzle cap in position for protecting and sealing the nozzle.

Fig. 3 is an enlarged elevation partly broken away and with parts separated to illustrate certain structural features.

Fig. 4 is a detail of the feed screw.

Fig. 5 is a sectional detail of the closure cap of the storage chamber.

Fig. 6 is a detail in plan and elevation of the spring washer.

Fig. 7 is a plan and side elevation of a retainer washer showing the initial form of the same prior to being straightened in its spring retaining position.

Fig. 8 is a perspective view of the feed piston.

In the form shown in the drawing the applicator comprises a penciliform body or barrel 1, having a knurled head 2 at one end anda special applicator tip 3 at its opposite end. This applicator tip, as will appear from the drawing, might be defined as being of conoidal form with an outlet aperture 4 at its apex.

The tip is preferably of elliptical'cross section and its longitudinal section in the plane of Fig.

2 is bluntly elliptical, while in a plane at right angles it is sharply elliptical, as shown in Fig. 3. This formation has been found to be particular- 1y advantageous for the application of rouge since the liquid or pasty pigment can be applied with considerable accuracy by means of the perforated tip, and then spread as may be desired by the of one by the other.

conoidal sides of the tip.

The cap 5 is shaped to fit the body 1 of the applicator rearward of the tip and to clear the major surfaces of the conoidal tip to avoid the soiling Within the cap I provide an inwardly projecting button or point 6, which enters and seals the nozzle aperture 4 and limits movement of the cap so that in its final position its inner walls, except for the point 6, are clear of the walls of the applicator tip.

The barrel 1 has a storage chamber 7 in its interior and the walls of this chamber are cylindrical except for longitudinal grooves 8 that are cut in diametrically opposite sides thereof. Within the chamber 7 there is a piston 9, the form of 5 which is shown in perspective in Fig. 8 and which is preferably formed of a soft rubber .body surrounding a core or nut 10, which is preferably of metal or some material appropriate for threading onto the feed shaft 11. The working face of the piston is cupped to provide a flexible marginal flange 12 for insuring tightness of the piston. The rubber body of the piston is provided with fins 13 as will be seen from Fig. 8, which are shaped to fit the grooves 8 in the chamber walls of the barrel. At the end opposite the applicator nozzle the barrel 1 is reduced in diameter and threaded at 14 to receive a closure cap 15 in which the shaft 11 is journaled. The head 2 is carried by and fast I on the end of the shaft 11, and is drawn snugly into frictional contact with the cap 15 by means of a spring washer 16 bearing between the inner face of the cap 15 and a retainer ring or washer 17, which is seated in 18, in the shaft 11.

The washer 16 is simply curved as illustrated in Fig. 6 and should be of hardened steel, whereas the retainer washer 17 detailed in Fig. 7 should be of untempered material such as soft steel or brass. This preferably consists of a washer shaped disc with a central aperture 19 small enough to engage the shoulder on the shaft at the side of the groove 18, and the material of this washer is cut away in portions as by the slots 20 so that this washer can be initially deformed into a somewhatv conical shape as shown in the lower part of Fig. 7, so as to enlarge the opening 19 temporarily to permit the washer 17 to be slid along the shaft without injuring the delicate 00 threads thereon. After the washer 17 is in place it may be set by straightening it with a tubular tool slipped over the shaft 11 so as to reform it to its original flat shape and cause the marginal lips of theaperture 19 to enter the groove 5v 18 in the shaft and bear on the shoulder thereof, thus retaining the washer 16 under compression.

The material of the washer 16 is suitably pro portioncd to bring about the right pressure bea suitably located groove 85 tween the head 2 and cap 15 so that there will be a degree of frictional resistance to rotation of the head so that it is retained in any position to which it is turned by the operator.

After the assembly of the head 2, cap 15 and shaft ii is completed the opposite end of the shaft 11, which is counterbored at 21, is expanded to form a shoulder 22 that limits the movement of the piston 9 and prevents an operator from injuring the device, as might be the case if the piston could be forced too far in an effort to empty the device. This is important because the exterior parts of the device may be made of somewhat ornamental, delicate or fragile materials such as phenolic condensation products.

In operation the device is filled by unscrewing the cap 15 and withdrawing the shaft 11 and piston 9, ,and then pouring the rouge or other contents into the cylindrical bore, to a suitable depth to allow room for the piston above it. The piston is then screwed to its upper limit on the shaft 11, and then the parts are assembled by pushing the piston into the barrel with its fins registered with the grooves 8 and finally screwing the cap tightly in place.

By reason of the left-hand thread on the shaft 11, right-hand rotation of the head 2 will advance the piston 9 'along thebore so as to force some of the contents to ooze from the nozzle 4. A reverse movement of the head 2 causes the material to run back into the nozzle aperture under the pressure of the external atmosphere. In

order that there may not be too much friction in the small aperture 4 resisting such return movement it is preferable to extend the body bore beyond the end of its cylindrical portion as by the cavity 23 in the reduced portion of the conical tip.

When the cap 5 is in place on the barrel 1, as in Fig. 2, the point 6 enters the aperture 4 and seals it and at the same time limits the movement of the cap 5 so that it does not contact with the applicator surfaces of the tip 3.
