2 Claims. (Cl. 15-'569) This invention relates to a fluid applicator and more particularly to a novel dauber for use in applying cos- 'metics or medications on the person of the user or for applying oils, lubricants, polishes or the like, on any suitable .surface.

An object of this invention resides in .the provision of means facilitating the application of cosmetics or medications on the person of the user.

A further object of the invention resides in the provision of means controlling the flow of fluidthrough a dauber so that the harder'the dauber is pressed against the 'surface'being treated, themore fluid is permitted to flow through the valve utilized therein.

A further object of the invention resides in the provision'of a dauber employing a novel valve structure in which a valve member is continuously urged against a valve seat by means of resilient legs, which resilient legs are secured to an insert or retaining ring fitted in the neck of the container.

Yet another object of the invention resides in the .provision of means aflfording protection for the surface a of the body of the user applying the dauber by providing a soft and rather large area contact for the dauber, yetproviding better control for the flow of fluid from the dauber by employing a mechanical'valve structure.

In the past, daubers have been produced which employed one or more layers of foam rubber at the ends thereof through which fluid flowed. However, these former daubers are unsatisfactory since the flow of even light-weight fluid therethrough is severely restricted and the daubers are completely unsatisfactory for heavier or thicker fluids.

Other daubers have been produced which employ a mechanical valve but these daubers generally have a reduced contact end, which often causes severe discomfort to the user since the amount of pressure required for actuating the valve member is applied over a minimum surface area of the skin of the user.

Therefore, it is a yet further object of the present invention to provide a dauber eliminating all of the aforesaid disadvantages of prior art daubers yet which is inexpensive to manufacture, simple to use, eflicient in operation, capable of being used with liquids of various viscosities, and which is attractive in appearance.

These, together with the various ancillary objects and features of the invention, will become apparent as the following description proceeds, are attained by this dauber, preferred embodiments of which have been illus trated in the accompanying drawings, by way of example only, wherein:

Fig. 1 is a side sectional view of a dauber constructed in accordance with the concepts of the invention, with parts thereof being shown in section for greater detail;

Fig. 2 is an enlarged detail sectional view of a portion of the dauber showing in particular the construction of a valve means utilized in the invention;

Fig. 3 is a planview looking in the direction of line flltd States Pate t ICE 2 III-III in Fig. 2, with a portion 'of'the cover being broken away to show valve structure in detail;

Fig. 4 is an enlarged sectional detail view as taken I along the plane of line IVIV in Fig. 2;

"Fig. '5 is a artial sectional view of a modified form of the invention in which there is provided a valvemember of unitary construction;

Fig. 6 is a partial sectional detail view of a modified form of valve structure in which the valve seat is provided with a groove forming a fluid reservoir; and

Fig. 7 is a partial sectional detail viewillustrating a modified means for securing the coverinplace.

With continuing'reference to the accompanw'ng drawings wherein like reference numerals designate'similar parts throughout the various views, reference numeral 10 generally designates the dauber comprising the present invention, which includes a fluid container for medications,rco'smetics, or the like, such as skin bracers or tonics, lotions or perfumes, fungicides, etc.

Thecontainer 12 is provided with external threads at 14 on which a cap 16 isiadapted to be readily secured. 'I'he retaining'ring '18'forming an insert is, forced within the neck 20 of the container 12, the retaining ring 18 preferably .being integrally molded of any suitable material including synthetic plastic resin or 'the like. Fitted within an innerflange not :the retaining ring 18 is a valve seat24 having a tapered surface'26 cooperating with thefco'nical porti'on.28 of a valve member The valve member 30 is provided with a downwardlyextendin'gportiojn 32'having a series of grooves 34'therein allowin g ready flow of'fluid therein when the valve member is in' an open position andthe surfaces 26 and. 28 are spaced.

The retaining ring 18 is provided with 'aportion of enlarged cross-sectional area formingan inner "peripheral flange on shoulder 36 against which the valves'eat24 abuts. The flange, 36 defines a peripheral 'aperture-75.

The valve member 30 includes'a plurality'of legs 38 of a resilient springy material 'chosenfrom any'suitable syntheti'c'resin'or the like and which as'is shownLinFig. 4 may conform'in .contour to the icontour of the projection 40 of the 'retainingring 18, thus being arcuate in shape and engaging the retaining ring overalarge surface area. The projection 40may have a molded rim as at 42 at the lower end thereof or, optionally, the lower end may be swaged. over thetip endsv of the legs 38 to securely hold the legs '38 in place. 'Ihe legs may be molded in .a unitary manner including a center piece 44 which in turn may be integrally formed with-the other .portion of the valve member 30, or whichmay'beheld thereto by-me'ans of nut and'

bolt

46 and 48,'respec'tively.

In addition to the inner flange 22, which may be of cylindrical configuration and which may be provided with a recess 50 therein as well as a shoulder 52, is an outer flange 54. Positioned between the outer flange 54 and the inner flange 22 is a cover 56 formed of a disk 54 of porous material, such as foam rubber or the like.

A layer of fabric 60 porous, and relatively soft and smooth surfaced overlies the foam rubber 54 to prevent deterioration thereof. The flange 54 is crimped or swaged in such a manner that it holds the peripheral edges between the inner and

outer flanges

22 and 54, respectively, in a securely locked manner within the arcuate surface of the outer flange 54, providing a smooth contact surface.

In operation, the fluid in container 12 will pass through the valve when the cover 56 is pressed against the valve member 30 so as to move the surface 28 away from the surface 26 allowing fluid flow. This will cause the legs 38 to how after being placed under compression. As soon as the valve member is released, the legs will force it backinto a closed position. Fluid flowing into the space 62 between the cover 56 and the valve member 30 3 and valve seat 24 will pass through the porous cover 60 onto the skin of the user or onto any other surface being treated. Hence, the greater the compression of the valve, the greater the fluid flow.

In Fig. 5 there is shown a modified form of the invention in which conical valve member 80 cooperates with a conical surface 82 of a valve seat 84. The valve member 82 is integrally formed with the legs 86 which correspond to the legs 38, it being noted that the valve seat 84 is provided with an enlarged passage 88 so that the conical head of the valve member 80 can pass therethrough.

In Fig. 6 there is shown a yet further form of the invention in which the valve seat 90 is provided with a groove 92 therein so that fluid entering into the space corresponding to the space 62 between the cover and the valve seat will flow into the reservoir 92 when the dauber is in an upright position, permitting an immediate source of fluid to be available and to soak through the foam rubber cover, even prior to depression of the valve member.

In Fig. 7 there is shown a modified form of means for holding the cover 56 in place, which includes the concept of forming the inner flange 100 and then swaging the outer flange 102 to form a shoulder 104 which clampingly engages the cover 56 holding, holding the cover between the shoulder 104 and the flange 100.

Thus, it can be seen that there has been provided a dauber or applicator including a fluid container 12 having a neck terminating in an open end. A retainer ring or insert 18 having a projecting portion 40 is fitted in the neck. A porous resilient cover 56 is secured to the ring 18 and a valve seat 24 is fitted in the ring with a valve member 30 being movable with respect to the valve seat 24 secured to the projecting portion by means of a rim 42. The valve member 30 cooperates with the valve seat 24 to control the flow of fluid from the container 12 to the cover 56 which is depressable into engagement with the valve member 30 to move the valve member to an open position.

Various changes and modifications may be made without departing from the spirit and scope of the present invention and it is intended that such obvious changes and modifications be embraced by the annexed claims.
