It isalready known in the prior artto form hollow teeth in a comb for the more efficient dispensing of fluids, fromthe teachingof US. Pat. No. 3;,10l,O86;.issued Aug. 20, 1963; to S. S. Di Vito; for instance. Such prior teaching, however, most'often has no provisioning on the comb fora'rigid handle whichis so necessary.

to competent use.

There is some. prior art, US. Pat. No. 3,376,065,

i being typical, which does disclose the use of an integral handle for the hollow-tooth comb, but in such art there is either noprovisioning orno suggestion of the use of a:flexible hose. Yet, the provisioning and accommodation of -.a hose with a hollow-tooth comb-type dispener is virtually-a necessity.

Theyprimary purpose, of the hollow-tooth comb-type dispenser is to insure the penetration of the. fluid dep into the scalp or'skin of the'subject. Now, this being so, itis no ,less necessary thatwashing or drying lfuids also be facilely. accommodated for the samedeep penetration -.efficiently. to purge and dry the scalp or skin.

I ltis an'object of thisinvention to answer th'eneeds leftunfilledbythe prior art-fluid dispensing applicators. It isanother object to cure the defects found in the prior art fluid dispensers. Specifically, it as anobject of this invention to set'forth anapplicator assembly for dispensing, fluids, and for conducting fluids therethrough; comprising an elongated comb; said .comb havinga rigid handle at one end thereof, a spinepors tion co-extensive. of an contiguous with said handle, and a pluraltiy vof teeth depending perpendicularly, rela tive to said handle, from'the. other end thereof; said comb further having a conduit formed within said spine portion; each tooth having a passageway formed therein which opens at one end onto saidconduit and which opens at the end opposite on the depending termination of ,said tooth; said comb also having at least one aperture formed therein, intermediate the ends thereof, whichopens onto, said conduit; said aperture having .means for threadedly engaginga threaded coupling a-fle'xible hose; said hose having first coupling means on one end thereof, for threadedly engagingsaid aperture, and second coupling means onthe opposite end thereof for effecting engagementthereof with a souce of fluid; and a universal coupler, having a plurality of coaxially and threadedly engaged coupling sleeves of discrete cross-sectional dimensions, one of said sleeves having threads formed therein and a crosssectional dimension which complements said aperture and accommodates threaded engagement of. said one sleeve withv saidaperture. I

Further objects and featues of this invention will become more. apparent by reference to the following description taken in conjunction with the accompanying FIGS, in which:

FIG. I isalongitudinal, cross-sectional view'of the novel hollow-tooth comb of the applicator assembly, according to the invention;

FIG. 2 is an end view of the conduit aperture, taken along section 2+-2 of FIG. 1;

FIG. 3 is a discontinuous, mostly cross-sectional-and longitudinal view of the flexible hose of the novel applicator assembly;

FIG. 4 is a fragmentary view, in cross-section, of the compliant-sleeve coupling end ofthe hose of FIG. 3,

the same being shown in rolledout'disposition; and

FIG. 5 is longitudinal or axial cross-sectional view of the inventive universal coupler of the novel applicator assembly, according to the invention.

As shown in FIG. 1, the novel applicator assembly comprises a comb 10 having a rigid handle 12'(only a portion of which is shown) and a spine 14, the spine being co-extensive of said handle 12 and contiguous therewith. The spine 14 has a conduit 16 a formed therein, and the comb 10 has at threaded aperture 18 formed therein substantially whereat the handle 12 and the spine 14 meet, said aperture 18 opening onto the conduit 16.

A plurality of teeth 20 depend from the comb l0, perpendicularly from the spine 14 and halde l2, and each of the teeth is hollow; the same have a passageway 22 formed therein which communicates, at 24, with the conduit 16. g

Conduit 16, shown in an end view in FIG. 2, hasa threaded surface formed therein at 26 for threadedly engaging ,a source of fluid, and has a prescribed inside diameter here represented as Z. 5

Referring now to FIG. 3, the flexible hose 28 can be seen in cross-section. Hose 28 has a first coupling 30 at one end thereof, the latter having a knurled annulus, and comprises means (not shown) accommodating both sealing and rotation of the coupling 30 aboutjthe hose 28. Such end couplings are well known in the art, so further discussion thereof is deemed not necessary here, however, coupling 30 contemplates such a component having external threads 32, ahd having an outside diameter of z dimension, which complement the threads and diameter of aperture 18. Hose 28, according to this embodiment, is formed of plastic. However, rubber and like flexible material could well be used.

Adjacent to one end of hose 28, and internally thereof, are formed a plurality of diverse-

diameter ribs

34, 36, 38 and 40. A' complementary plurality of tapered surface annuluses recede from the ribs, the annuluses bearing index numbers 42, 44, 46 and 48. Any combination of a rib and an annulus will cooperate to engage a depending pipe-outlet of a faucet, or the like, to secure the hose end thereat. For wider-mouth engagementrequirements, hose 28'further has a thinner gauge compliant sleeve 50 contiguous therewith. ,The sleeve 50 tenninates in an annular ring 52.with which sleeve 50 is rolled up for storage. Such storage disposition is shown in FIG. 3, whereas a fragmented end .of. sleeve 50 is shown rolled out in FIG. 4. This compliant sleeve facilitates the fluid coupling of the hose 28 with the output pipe of a hair dryer, or the like. i

From what is known in the prior art, it is customarily necessary to have a prescribed bottle, with a prescribed neck or throat size and thread, to threadedly engage the .same with a hollow-tooth comb-type of applicator. Now, this is rather limiting, as the multitude of sham poos, rinses, scalp medicants, and the like whichare available on the market are merchandised in a plurality of bottle types. What has been needed in the art is a universal type of coupler which will accommodate vari-,

ous supply throat sizes and threads to a fixed size and this end, my invention comprises such a universal coupler having a plurality of throat or neck sizes and threads.

The universal coupler 54, shown in FIG. 5, comprises set forth in the objects thereof-and in the accompanying claims.

I claim:

1. An applicator assembly for dispensing fluid, and

a base coupler sleeve 56 having an outside diameter of 5 for conducting fluids therethrough, comprising:

Z and having threads thereabout, at 58, which complement the threads and diameter of aperture 18 (FIGS. 1 and 2). Further, sleeve 56 has two sets of inside diameters and threads, at 60 and 62, to accommodate coupling thereof with fluid sources of two diverse diameters and threads.

Sleeves

64, 66, and 68, coaxially and threadedly coupled to sleeve 56, are similarly dimensioned and threaded for progressively largemouthed fluid sources. The threaded cooperation of all the

sleeves

56, 64, 66, and 68 facilitates the retraction of given ones to allow coupling access to a prescribed one, so that all threaded surfaces of each of the sleeves can be made available for use. Such relative positioning or movement of the sleeves is represented by the dashed-line positionings in FIG. 5.

Not unlike the prior art applicators, the instant applicator assembly insures the deep-down skin or scalp treatment with fluids, such as shampoos and the like, for human application, and flea and/or tick ablutions and the like for aminal application. Further, however, the applicator assembly here presented and disclosed teaches the use of a flexible hose, and sets forth coupling accommodation of the hose, for the necessary hygienic flushing of the skin and scalp in the same penetration as effected by the treatment fluids. in addition, the novel comb here set forth incorporates a rigid handle so that, if the treatment fluid comprises a flexible bottle, the latter can be deployed in threaded engagement with aperture 18 and squeezed against the handle 12 to cause the discharge of the fluid from the bottle. Often enough it will be sufficient to so engage the container or bottle and allow the fluid to flow therefrom, freely, into conduit 16. Then, to flush the scalp and to purge the comb as well it is only necessary to thread coupling 30 into aperture 18, and secure the other end of hose 28 to a cource of water, or whatever. Then too, as noted, the compliant sleeve 50 will facilitate the attachment of the comb to a hair dryer, or the like.

While I have described my invention in connection with a specific embodiment thereof, it is to be clearly understood that this is done only by way of example and not as a limitation to the scope of my invention as an elongated comb;

said comb having a rigid, imperforate handle at one end thereof, a spine portion co-extensive of and contiguous with said handle, and a plurality of teeth depending perpendicularly, relative to said handle, from the other end thereof;

said comb further having a conduit formed within said spine portion;

each tooth having a passageway formed therein which opens at one end onto said conduit and which opens at the end opposite on the depending termination of said tooth;

said comb also having at least one aperture formed therein, intennediate said plurality of teeth and said handle, which opens onto said conduit;

said aperture having means for threadedly engaging a threaded coupling; and

a universal coupler, in threaded engagement with said aperture, said coupler having a plurality of coaxially and threadedly engaged coupling sleeves of discrete cross-sectional dimensions, one of said sleeves having threads formed therein and a crosssectional dimension which complement said aperture and which effect said threaded engagement of said coupler with said aperture; wherein said sleeves of said universal coupler each have a plurality of not less than three threaded surfaces for effecting engagement thereof with sources of fluid; and

said threaded surfaces of said plurality thereof comprise a threaded inside diameter and a threaded outside diameter.

2. An applicator assembly, according to claim I,

wherein:

all sleeves of said universal coupler, excepting one,

are of common length.

3. An applicator assembly, according to claim 1,

wherein:

said one sleeve of said universal coupler is of greater length than any other sleeve of said universal coupler.
