'4 Claims.

The present invention relates to a device for applying viscous liquids, and more particularly to means for applying nail polish to the finger nails.

Heretofore it was customary to apply nail polish to the fingers by providing a brush and dipping the same in the nail polish after which the brush was applied to the nails. This operation required the user to see to it that just the right amount of liquid was on the brush and to apply the same carefully to the nail as otherwise some of the polish was apt to drop off or to run into undesired areas.

It has been proposed to overcome this difficulty by providing an applicator resemblin a fountain pen and consisting of a rigid tube closed at the upper end and having a flexible rubber lower end. A brush was fixed within the flexible rub ber tube and a small opening at the bottom of said flexible tube provided means for allowing the dropping of liquid onto the brush. A bafile was provided to direct the liquid onto the brush.

Such a device has not come into any substantial use as it suffers from inherent disadvantages. The cost of manufacture is relatively high due to the necessity of making all of the parts of special form and materials. The small opening at the bottom of the flexible tube has a tendency to become clogged by the evaporation of th e solvent from the natural polish so that feeding of the polish to the brush-is uncertain. Also, in the use of the applicator the fingers press upon the flexible tube so that when pressure was applied for spreading the nail polish, an excess of more polish was likely to be dropped onto the brush or fingers.

.The present invention is intended and adapted to overcome the difiiculty and disadvantages inherent in prior structures, it being among the objects thereof to provide a device for applying nail polish which is simple in construction and convenient in operation.

It is also among the objects of the present invention to provide an applicator for nail polish which contains a sufiicient reservoir so that an entire set of nails may be coated with the polish with but a single filling of the applicator.

In practicing the present invention there is provided a bottle or jar or the like containing nail polish. Said bottle has a cover or cap which is usually of the internally threaded type. There is provided a tube passing through a central openingin the cover and a bulbof resilient material is secured to'the upper end of the tube above said. cover. The lower endof the tube is .of said tube. T p er nd. oftube 61s flang and the .below the constricted portion thereof.

By such an arrangement the brush is made detachable so that it may be removed at any time for replacement or for cleaning. The diameter of the entire applicator is not substantially greater than the diameter of the cylindrical tube so that there is no interferencewhen the applicator is introduced into or removed from the bottle or jar.

There is provided a bottle I having a neck 2 which is threaded, the bottle being filled to a suitable height with a liquid nail polish composition. A cap 3 having an internal thread 4 00- A central cylindrical opening 5 in said cap or cover 3 has a cylindrical tube 6 usually of glass or the like, passing through the same and fitting tightly in said opening 5. The lower end of tube I 6 is formed with a tapered portion 1 and terminates in a cylindrical constricted end 8 of subprovides a constricted opening 9 at the lower end by rivets l8.

adapted to embrace tube 6.

d 9. liquid droppingoff of the brush. Also theopenlower edge H of a resilient rubber bulb [2 or the like fits tightly around flange l and acts as a seal for tube 6 and cover 3. Bulb 12 is adapted to be gripped by thumb l2 and forefinger M. A brush I5 is held in a base I6 and a thin fiat handle I! has its lower end secured to base I6 The lower end IQ of base is is approximately opposite opening 9 ,so that as liquid emerges from.-said.opening,, it, immediately comesin contact withibrush. l5;wliich-is.;adjacent thereto but which does not obstruct the flow of liquid therefrom.

A clip is secured by any suitable means to a pair of arcuate arms 2| and 22- whichare Said arms have suificient resiliency so as tozgrasptubelfir andi frictionally hold brush 15in position. Arms, 2|.

and 22 approach each other, leaving a relatively small opening 23 between them and a central opening-2'4, the size of Which is slightly less than thev outer diameter of'tube 6 I By this arrangementbrush l5 is-rheld in they 'desi'red position relative to' opening 9 as-showrr in: Figs. 1' and 2; Handle- I'l is-in longitudinal .j contact-with tube 6 and'bei-ng fiat and relativelythin, does not add'substantially-to thediameter there-oi." Base H5 is-of such size that it" fills thespace between the lower: end'of'handle I-T'and constricted portion a Thus the -brush is substantia-lly within the area defined by aprojection of-the uppersurface of' thetube 6*and'does not extend laterally beyond tube -B and at the -same time is held in such close-relationshipto opening' 9 that each drop 0f liqu-id 25 as it emerges immediately contacts Withbrush l5 an'd is absorbed-by: the brush, since the-brush is substan tially in direct contact with the wall of openin Thereby there -is no danger ofany ofthe ing 9 is always free and clear so that there'is no interference withthe flowof liquid when bulb [2' is pressed. In using "the applicator; the parts are: in the position .shown in Fig; l andbulb' i2 is-pressed5by thumb and forefinger so' as toexpel air, andlthen released" This fills tube- B to v the desired point with the relatively viscous nail polish and cap this unscrewed. and removed from g the bottle;

pressure may again .be applied to bulb l 2-,to; cause an additionaldrop .25 to fall upon and .be.a b-- sorbed. by brush I5.. The operationcma-ythen. continue. until the. application to. thenails has been completedand the applicator is-thenre.-

turned to bottle I.

Because of the specific ,details. of construction ofj'thedevice, the applicator maybe used'with. certainty to coat fingernails and. toenails w-ith--- out danger of extending the coating. beyond :the; nails Also the hand of the user isso.farre-,- I moved fromthe nail polishthat iitre mains clean.

.the upper end of handle l1 and-is provided with 4 A better and smoother coating on the nails is obtained thereby;

Although the invention has been described setting forth a single specific embodiment .thereof, the invention is not limited thereto but various details of the construction of the device may be altered within the spirit of the invention. For instance, the formation of the several elements-such as bulb, can, tube, brush and the like. may be altered considerably; The, materials of construction may be of any type suited for the purpose, as for instance, tube 6 need not be made of glass but may be made of metal, hard rubber, plastics or the like. The handle and associated parts. may. be made of metal, plastic material or any other substance having the desired properties;

Theseand other changes in the details of construction'may be made without departing from the principles set forth herein and the invention istherefore to-be-broadly construed and not to be limited except' by the characterof the claims appended hereto;
