Patented Apr. 17, 1951 UNITED STATES PATENT OFFICE WICK-FEEDING MEANS FOR APPLICATORS l OF COSMETICS AND THE LIKE Dezelle Oistrander, South San Francisco, Calif. Applicationqune`24, 1946, Serial No. 678,769

w1 claim. (ci. 15--1s4) This invention relates to applicators and is especially adapted to provide a sanitary and convenient means of applying various medicinal or cosmetic liquids, salves, pastes, etc. to skin surfaces.

An important object of the invention is to provide an applicator of this character which employs a wick which is previously impregnated with the substance to be used or wherein the wick absorbs the substance by capillary attraction, especially when the substance is in a liquid state- Another important object of the invention is to provide an applicator for substances, as named, wherein an applicating wick is employed, that may be advanced and cut offconveniently.A

Still another object of the invention is to provide an applicator for the purposes stated, wherein a wick is provided for supplying the desired substance from a container or reservoir, and wherein convenient complemental cutting means is provided whereby the used end of the wick can be cut off from time to time, especially when the applicator is to be used by different persons.

These and various other important objects and advantages of the invention, will become apparl ent to the reader of the following description.

In the drawing:

Figure 1 is a longitudinal sectional View through the applicator;

Figure 2 is an enlarged fragmentary sectional view taken on line 2--2 of Figure 1 or Figure 2;

Figure 3 is a reduced side elevational view of the device;

Figure 4 is a cross section taken on line 4-4 of Figure l.

Referring to the drawing, numeral 5 denotes a substantially bullet-shaped shell, the same having a cylindrical portion a and a gradually constricted nose portion b.

The reduced end of the shell 5 is cut off bluntly as at 6 and has an opening 'I therethrough for receiving the plug portion 8 of a cap 9 which may have a ring I0, and to also slidably receive a tube I I which forms part of the internal mechanism of the applicator.

An elongated reservoir I 2 contains a substance I3, which may be a medicinal or cosmetic liquid, salve, paste, etc. and into this extends a wick, preferably of felt and denoted by numeral I4. The wick extends through the tube II and partly projects beyond the free end thereof, as shown in Figure 2.

The reservoir I2 has a slight taper inwardly,

so that there will be a frictional engagement of 55 2 the outer end thereof with the adjacent interior of the shell 5.

The reduced end. of the reservoir I2 has a threaded opening I5 for receiving the adjacent threaded end of the tube II. Radiating from this end of the tube I I is a flange I6, xed to the tube and from this point, longitudinally of the tube II, the latter is formed with a slot I1, into which a feed spur I8, formed from a second flange I9, located on a collar20 projects. The collar 20 with its flange I9 is slidable on the tube IIL Av coiled compression spring 2I,. circums'cribes the tube I I `and is interposed between the flanges I6, I9. i The feed spur I8 projects at an angle into the tube II so as tobarely bite into "the wick I4.

The lower end of the reservoir I2 has a hemispherical-shaped head 22, the central portion of which has a recess 23 for receiving the plug and cap 8, 9 when the applicator is being used.

In the use and operation of the applicator, the cap 9 is first removed from the applicating end of the device and the plug 8 thereof inserted in the recess 23 of the reservoir head 22, so that it will not become lost. By pushing inwardly on the head 22, the reservoir I2 is urged inwardly until the flange I9 abuts the reduced end of the shell 5. The parts will thus assume the position shown in Figure 2, with a short portion of the wick I4 protruding, and this is used for applying cosmetics, medicinals and other substances.

If it is desired to remove the tip of the wick, as when another person is about to use the same, the tip can be cut 01T by means of a cutter generally referred to by numeral 24. This cutter is a sleeve which snugly ts the cylindrical portion of the shell 5 and has a diamond-shaped opening 25 therein, the edge portions of the sleeve at said opening 25 being sharpened to provide cutting edges 26. This sleeve is slipped olf of the shell 5 and laid across the blunt end 6 of the shell 5 with the tip of the wick protruding through the opening 25. By pulling the cutter across the blunt end 6, the tip is cut oft".

It will now be necessary to extend the wick for use, and this is accomplished by forcing the reservoir I2 inwardly so that the tube II is projected a short distance beyond the blunt end 6 of the shell 5, that is until the spring 2I is fully compressed, or the ange I B has touched the adjacent end of the collar 20. During this movement of the tube II, the wick I4 has been carried over the slightly impinging feed spur I 8, but upon releasement of the reservoir I2, the spring 2I will exert force on the reservoir, urging the same outwardly, and in so doing, the wick I4 will/be caught against the feed spur I8 and retained as the tube II moves inwardly with the reservoir. Thus, when the parts have returned to the position shown in Figure 2, or to the position shown in Figure 1, a portion of the wick will be protruding beyond the free end of the tuber l I.l

Obviously, the various parts of the device can be manufactured of any desired material, and perhaps plastic or some material yet to be dis#` covered will be foundsuitable.,

It will also be found obvious that there(- is no waste of the substance being applied, whether it be a medicinal or a cosmetic;

thorough brushingy action of the material onto the skin can be accomplished by the small protecting tip portion of the wick.

While the foregoing description sets forth the invention in specific terms, it is to be under- .stood that` numerous Ychanges in the` shape, size and materials may be resorted, to without departing from the spiritI and scope of the invention as; claimed hereinafter.

Having described they invention, `what is claimed; as new ist:

An applica-tor comprising a. shell, a substance containing reservoir: disposed slidablyY through one end of the shell, the otherV endlof the shell a `being formed with an opening, said. cartridge Vbeing provided withV a sleeve extension disposed in the last mentioned opening, a anged collar on the sleeve adjacent the reservoir, a, second flanged collar through which the sleeve is slid- 'I'he applica tion is done from a wick, impregnated, and a vthat portion of the wick extending inwardly into the cartridge to bite into the wick, said tooth adapted to retain the wick against return, with respect to the shell on the inward movement of the reservoir with respect to the shell and. outwardly of the reservoir, on the outward movement of the cartridge with respect to the shell?.
