Description

plicators for cosmetic powder.

Patented June 11, 1940 UNITED STATES PATENT OFFICE Applications ?(,C1L93]::;i8a;)N0. 301,892

a The present invention relates generally to ap- More particularly the invention relates to that type of cosmetic applicator which consists of a pad or disclike body which is formed of porous latex rubber and has in addition to a skin on the top face thereof a slit or kerf leading into-the interior of the body and forming a pocket for a charge of powder.

The primary object of the invention is to provide a cosmetic applicator of this type which is an improvement upon, and has certain advantages over, that which is disclosed in, and covered by, United States Reissue Letters Patent consideration of the following detailed descrip-' tion.

The invention consists in the several novel features which are hereinafter set forth and are more particularly defined by claims at the a conclusion hereof.

In the drawing which accompanies and forms a part of the specification:

Figure 1 is a top or plan view of an ornamented applicator or compact. made in accordance with this invention; and I Figure 2 is a side elevation of the sa In the embodiment selected for illustration .there is shown a circular disc compact ll having a diameter approximately five times the thickness of the disc.

. its opposite faces the body of the compact is slitted by any suitable means to form an interior kerf 12 for the reception of a cosmetic powder or rouge, said kerf having substantialLy the contour indicated by the dotted line I (Figure 1); The kerf thus provided opensat I! through the edge of the compact, and permits the insertion of the powder into the kerf, as described in my aforesaid patent.

The compact is made of sheet latex rubber substantially devoid of filler and of the typ having a thin skin II and a body 20. The body has pores varying in size from microscopic to a maximum of the order of magnitude of 0.0750

Substantially midway between inch. Occasional much larger pores in the nature of minor blemishes are not harmful if they are few enough and sufllciently separated not to affect the rate of percolation of powder through the body as a whole. ranging from 0.0018 to 0.0060 pound per cubic inch, a density of 0.0040 havingvbeen found very satisfactory. Such a density provides the desired permeability to pulverulent materials as to permit ap'recisely controlled application of powder to, the skin of the user when the compact is illled and applied as disclosed in my prior patent.

jThe body 20 is flexible and can even be folded sharply on itself through an angleof' 180 degrees without permanent distortion, but it has sumcient mechanical strength to hold its shape under its own weight. Even when resting on its edge, abody one-half inch thick and substantially circular with a diameter of 2% inches, which is one of the common sizes employed, does not flatten The body has a density 5 against its support through a contact subtending an angle of more than thirty degrees.

The skin I 8 is of a thickness of the order of magnitude of iive thousandths of an inch, although shown exaggerated in the drawing, and has relatively smaller pores than those of the body 20. Such smaller pores make the skin I.

relatively impervious to pulverulent material but pervious to liquids and gases, thus facilitating cleansing of the compact.

The diflicuity of applying and retaining an ornamental coating or layer upon an elastic and porous surface has been overcome by applying the ornamentation in the form of an elastic and 1 flexible layer 22 such as a layer of colored rubber mixtures, which layer will adhere to the porous latex skin and stretch with the latter without cracking or peeling. when the ornamentation V V is prepared and applied according to U. S. Patent Without attempting to state definitely the extent or time of such action, I can state that the finished article with the design in place on it,

offers materially greater resistance to the exit of powder over the area where the design is, but

' can still be washed and cleaned readily.

' As illustrated, the ornamentation covers the With the end of the kerf terminating short of the edge of the device by approximately one and one half times the thickness of the bod the rate at which powder will work out at the periphery of the body is relatively greater near the center, materially'less on the flat face near the edge, and still less along the edge itself.

After the kerf I4 is cut, and either before or after the design is applied, I prefer to remove a small volume of the material at the center of the compact, as indicated by'the dotted lines at 26 in Figure 1 and 28 in Figure 2. This very materially increases the storage capacity of the device and at the same time further concentrates the charge of powder.

I have illustrated the body 20. as having an annular series of vertically extending parallel flutes or grooves in its edge or peripheral portion. These flutes or grooves extend from the top face to the bottom face and cause the edge or peripheral portion to have anundulatory or corrugated contour. This not only contributes to the ornamental appearance of the device, but

makes the edge an effective tool for distributing, or partially removing, powder previously applied with the flat face. The individual flute formed ribs along the edge are normally substantially devoid of powder and function as wipers when applied with the proper amount of. pressure. Their effective employment for such purposes is easily and almost unconsciously mastered by the user after a short period of use.

It will be obvious that the disc need not be circular, but that a flat body of any edge configuration may be employed. Many of the advantages of the invention would be the same if the slit I! opened through the periphery of the body elsewhere than through the edge.

Without further elaboration, the foregoing will so fully explain my invention that others may, by applyingknowledge current at the time of application, readily adapt the same for use under various conditions of service.
