Application March 20, 1947, Serial No. 735,913

1 20 Claims.

This invention relates to a manicure device, and more particularly to a fountain applicator for fluid such as paint which is adapted for treating the finger nails.

Devices of this character have heretofore been suggested which have attempted to provide means for avoiding the smearing of nail paint upon the flesh surrounding the nail.

Also, applicators of this character have heretofore been suggested which have been termed fountain applicators but which have had the serious disadvantage of having the fluid therein clog frequently. Fountain applicators have been employed previously for applying various cosmetic preparations in addition to nail paint, such as lip rouge, lacquer and the like. Many preparations of this type require a highly volatile solvent or vehicle in order to induce quick drying. Such preparations have a tendency to dry and to harden adjacent the outlet of the container, thereby clogging same.

Furthermore, such devices heretofore suggested employing the preparations of the above type have not only been subject to a hardening or drying of the preparations near the outlet of the container but the air entering the outlet of the container has tended to harden the entire contents or to make same too viscous. This, of course, makes it necessary frequently to replace the hardened or the extra viscous fluid, thereby causing considerable waste.

Also, applicators which have been employed in the past have failed to provide a proper guard or guide to assist in moving a brush attached thereto in a proper mannner whereby a smearing of fluid is avoided. A person having unsteady hands employing previous devices may never be able to accomplish a satisfactory application of, for example, nail paint.

According to the present invention, apparatus is provided which will eliminate the above noted difiiculties.

The invention in one aspect thereof comprises a brush which is partially enclosed by an arcuate therewith in such a manner that the outlet of the container is interposed, preferably between the shield and brush. The volume of material which the container can hold preferably is sufiicient for a single application of such fluid, for example, to ten finger nails. After one complete application, the container may be disposed of, thereby avoiding a clogging of fluid in such a container which normally is caused by long exposure to air. The container preferably is provided with a minute orifice which may be opened by withdrawing therefrom a small fibrous member such as a thread. The extremity of the container which is associated with the shield and the brush preferably is formed into an arcuate contour somewhat similar to the contour of the shield, thus facilitating the insertion of such an extremity in between the shield and the brush. The fibrous member preferably extends from this extremity.

Various further and more specific objects, features and advantages of the invention will clearly appear from the detailed description given below taken in connection with the accompanying drawings which form a part of this specification and illustrate, by way of example, preferred arrangements of apparatus for carrying out the invention. The invention consists in such novel combinations of features and apparatus as may be shown and described in connection with the device herein disclosed.

As illustrated in Figs. 1 and 2, the novel device is associated with a suitable means for adapting same for easy manual use. A rigid handle 20 is provided which may be in the general contour of a pen stock or shaft. The latter may be grasped as shown in Fig. 1. .1;

' {1 A novel shield, to be described more fully hereinafter is provided as at 2| and is preferably removably associated with the pen stock 20. Suitable means for detachably securing the shield to the pen stock or handle are provided, for example, comprising a shield support or shield base 22 (Fig. 6). The latter comprises a rigid elongated flat plate which is adapted for being held within a slot 23 of the pen stock 20. Ferrules or bands 24 and 25 (Fig. 6) may be secured to the shield support at suitable intervals therealong in order to hold the shield support within the slot 23. Thus the shield with its base 22 may be easily detached from the pen stock and may be replaced with cuticle brush means to appear hereinafter. Feet or supports 22a, 22b (Fig. 1) comprising, for example, short cylindrical members rigidly secured to ferrule 24 may be provided upon which the device may rest when temporarily not in use.

In order to prevent a smearing of a fluid such as nail paint upon a cuticle 26 and in order to provide a safe and dependable guide for fluid application to assist persons havin unsteady hands and, of course, those having normally steady hands, the above mentioned shield 2| is provided for a brush 21, comprising a plurality of elongated fibrousmembers or hairs secured to a common base. The latter is preferably mounted beneath the arcuate shield as viewed in Figs. 1 and 2 whereby it is partially enclosed by the shield.

The novel shield preferably is a cylindrical surface. The term cylindrical surface as employed herein has its normal geometrical meaning. The directrix of the cylindrical surface which defines the novel shield described herein, is preferably an open curve.

One example of the novel shield is shown in section in Fig. 4 wherein it comprises a section of a circular cylinder. The cylinder is not limited 'to' a. circular one. In general, the novel shield is an arcuate member which is adapted for overlapping or overhanging the brush 21 as shown in Fig. 2. The brush 21 is, of course, substantially in alignment with the arcuate shield. It is longitudinally narrower than the shield whereby the above mentioned overlapping or overhanging takes place. As shown in Figs. 2 and 5, shield portions 2| a overlap or overhang the brush 21. This paint is-employed, the overhanging portions Zla are effective to prevent a smearing of the paint upon the cuticle. Thus, it provides a rigid and easily handled guide for the movement of the brush and serves the additional function of a guard for pushing back the flesh where desired.

It is desirable for the free end (as opposed to the butt end) of the brush 21 to be coterminous with the shield. In other words, the tips of the brush and the shield should be substantially in aligmnent with one another,

It may become desirable and necessary to remove and replace the brush 21. Suitable means are provided for conveniently removing and replacing said brush comprising, for example, a brush securing collar 28 (Figs. 2 and 6) which may be moved axially of the shield 2| and which may, in the position shown in Fig. 1 urge the base or butt end of the brush into a small recess formed adjacent the inner extremity of the shield. In order to remove the brush, it is necessary only to slide the collar 28 from the position shown and to lift the brush therefrom.

One extremity of the shield is beveled as at 2|b (Fig. 2). This beveling permits and facilitates a contact between the tip of the brush and the nail. The shield, of course, may be constituted by a section of a cylindrical surface, the section being formed by a plane which is oblique to the axis of the surface.

As shown in Fig. 2, the butt end of the brush 21 is in spaced relationship to the peak of the shield. The significance of the position of said butt end is that it permits the insertion of an extremity of a fluid container between the brush and shield. A flexible removable and disposable cartridge or container may be associated with the novel shield and brush as at 3| (Fig. 2). Said container may be, for example, of elongated cylindrical contour and may be fabricated from paper or plastic or some suitable material.

It is desirable to support the container 3| in alignment with the shield 2| and the brush 21, and for the container to rest adjacent a pressure surface 20a (Fig. 1) against which it may be pressed by, for example, the forefinger as illustrated in said Fig. 1.

Suitable means are provided for supporting the container 3| in this manner comprising aligned sleeve members 32 and 33. These are substantially coaxial with the shield 2|.

Adjacent the inner extremity of the shield 2|, there may be attached a so-called conduit member or a tubular hollow member. This conduit is adapted for receiving and guiding the outlet extremity of the container 3| whereby the latter may be moved easily between the shield 2| and the brush 21.

It is desirable for that extremity of the container 3| which is to be adjacent the shielded brush to be formed into an arcuate or concave shape as shown at tile in Fig. '1. Thus the insertion of the container is facilitated, and the concave portion 3|a is adapted for receiving the portion of the shield which supports the butt end of the brush.

In order to provide a suitable orifice for the container 3| which may be readily opened and which will be sufiiciently small to avoid a flooding of material therefrom, a fibrous member such as a thread 35 is sealed into extremity 3|b. The thread may be looped and sealed by wax into said extremity. Any suitable frangible fluidproof or sealing material may be employed at extremity 3|b into which thread 35 extends.

Withdrawal of the fiber 35 provides a small opening as at 34 (Fig. 4) from which the nail paint or the like may be extruded by means of finger pressure. Of course, it is possible for the contents of the container to pass through the outlet by virtue of gravity or capillary action.

A consideration of Fig. 2 indicates that the contents of the cartridge 3| may be extruded therefrom or may flow therefrom upon the brush at a point intermediate the extremities thereof. This is a preferred embodiment of the invention. However, of course, it may be possible to feed a fluid from such a container into a conduit at a point somewhat removed from the brush and the conduit may lead the fluid to the brush and shield.

A feeding of fluid directly from a disposable cartridge to a point intermediate the brush extremities, as shown in Fig. 2, has the great advantage of providing a direct flow of liquid or fluid onto a brush which is guided by a shield. The latter may assist in moving the fluid along the brush, for example, by capillary action. Moreover, a hardening or caking of material in a conduit is avoided because the disposable container itself constitutes the conduit for leading fluid up to the shield and brush. A caking or hardening of fluid in the brush 2? may be overcome easily by soaking the brush in a suitable chemical. However, the clearing of a small conduit in which paint or the like has hardened cannot be easily accomplished without suitable reaming tools. The use of such tools is an inconvenience and should be avoided. The device above described avoids such a necessity and provides a positive and direct feed of paint or the like to the device.

The portion of the brush which may contact the finger nail is of importance and comprises the bottom or undersurface of the brush as viewed in Fig. 2 and, of course, the tip of the brush. Not all of the bottom surface of the brush (Fig. 2) may contact the finger nail but a sulficient portion thereof may accomplish this to provide a positive painting contact whereby a suitable quantity of liquid may reach the nail promptly. Because of the above mentioned guard or guide members Zia, this paint can not reach the cuticle and the latter may be pressed back to avoid contact with the paint. Moreover, the cuticle may be pressed back and the paint may be applied up to the normal border of the cuticle or scarf flesh.

In the embodiment of Fig. 8 a, cuticle brush is provided which comprises a stiff, hard group of bristles which may be held in alignment with the pen stock 26 in substantially the same position as the shield 21. A group of stiff bristles is shown as at 3B which extend considerably beyond a ferrule 31 which holds the bristles. Said ferrule is in substantially the same position as the shield 21. A tubular portion 31a. is formed at the inner extremity of the member 31 and into which a removable cartridge of cuticle treating fluid may be inserted, and may be opened in a manner similar to that of container 3|. Fluid can flow to the brush through the base thereof as at 360..

In accordance with one form of the invention it is possible to secure the brush 2! (Fig. 9) directly to a container 3 lb within a concave portion thereof as 3|c which is similar in shape to the above described arcuate shield of Figs. 1 and 2. Such a container 3119 must have sufficient rigidity to support the brush and to provide a shield which can perform the functions of shield 2|. However,

it may have sufficient flexibility, at least long a part thereof, to enable extrusion of the contents by, e. g., finger pressure.

A band 28a. may be employed for securing th brush to the container 3lb. The container outlet instead of being located at the tip thereof preferably is located at Ma which is above and intermediate the extremities of the brush. The container 3w may be removably secured to the pen stock 28 by suitable means.

In order to expedite and also to facilitate the spreading of nail paint or in order to aid in cleaning the brush 2?, it may be desirable to extend said brush beyond the tip of the shield. This may be done when it is desired to paint relatively large areas of nail which are not closely adjacent to the cuticle or flesh. Also, it may be desirable to make a small adjustment in the position of the tip of the brush and the tip of the shield.

Suitable means are provided for the above purpose comprising, for example, a movable support for the brush which, as shown in the embodiment of Fig. 10, is pivotally mounted upon the shield 2i. Such a support is illustrated at 39 and is pivotally mounted at 10, the brush 21 being secured by suitable means to a central portion of the support 39. The latter, in the form shown, is substantially a U-shaped member with the brush secured at the center thereof. As shown in Fig. 10, the movable support 39 is in its normal position wherein the use thereof most commonly may occur.

In order to define the limits of motion of the member '39, suitable limit stops as at 4! and 42 may be provided against which the member may abut in its extreme postions. Another form of the shield is shown in Fig. 12 and includes a member 29 of arcuate cross-section having sides 30 which are not in curved alignment therewith as are analogous portions 2Ia of shield 2!. The shield of Fig. 12 is somewhat in the shape of a channel member having a bottom of arcuate cross-section. Sides 30 overlap or overhang the brush 2'! and preferably are in spaced relation thereto as are said portions Zla of Fig. 2.

The term cylindrical surface is intended to cover the shields of both Figs. 1 and 12.

With reference to the term nail fluid, it is to be understood that this is a generic expression having reference particularly to nail paint and to cuticle fluid or the like.

While the invention has been described with respect to certain preferred examples which have given satisfactory results, it will be under stood by those skilled in the art after understanding the invention that various changes and modifications may be made without departing from the spirit and scope of the invention, and it is intended, therefore, in the appended claims, to cover all such changes and modifications.
