This invention yrelates .to improvements in disv l' pensing applicators; and the invention A.hasreference, more particularly, toa novel means for dispensing a selected substance and simultaneously applying the same to the hai-r.
The invention has for an object to provide a novel dispensing applicator .adapted to 4be .easily and conveniently manipulated .for tapplying a suitable substance, in either .powder or liquid form, to the .hairand scalp .of Athe human head or to the hair and skin of animals, and 4in such manner that thorough penetration of .the'ha'irby the dispensed substance, and Auniform distribution of the substance throughout the hair masses treated, will be assured without waste.
The invention has for ranother object to provide a novel dispensing applicator for the stated lpurposes which comprises a container lfor the substance to bedispensed, lan applicator comb aflixed to said container, and means for discharging the substancerrom .the container :in the path fof the applicator comb, :when :the latter, in use, is passed through the hair `to be treated.
The invention has .for aiurther object to -prov .vide .a novel dispensing applicator, as `above .characterized, which ,-is provided with xmanipulatable means for opening 4and .closing the container for and against discharge of the treating substance therefrom, including means for regulating the amount of treating substance discharged.
Other objects of the invention, not at this time more particularly enumerated, will be understood from the following detailed description of the same.
An illustrative embodiment of the invention is shown in the accompanying drawings, in which:
Fig. 1 is a side elevational view of a dispensing applicator made according to this invention; Fig. '2.is a bottom plan view of the same; Fig. 3 is a side elevational view with an outer body part of the container shown in longitudinal section, the container being shown in closed condition; Fig. ,4 is asimilar view with both the inner and outer body parts of the container .shown in longitudinal section; Fig. 5 is a transverse vertical sectional view, taken on line 5-5 in Fig. 1, the container being shown in closed condition; Fig.v6 is a view similar to that of Fig. 5, but with .the container shown in an open condition; andFig. 7 is a transverse vertical sectional view., taken .on line -1-1 inFig. 3.
Similar vcharacters of vreference are employed in the above .described views, to .indicate corresponding parts.
Referring .to v4.the drawings, the dispensing appllcaton in the illustrative 'embodiment thereof as shown, comprises a container member formed by an external tubular 'casing'or body I0, `within the interior of which 'is entered 'an internal tubular sleeve Il, which will vbe hereinafter referred to as the valve sleeve. The external surface lof vrthe valve sleeve IIl contacts the internal surface o'f the lcasing Jor body Ill, and said valve sleeve is' rotatively movable -relative to the casing or`body. In order to better assure a closely contacting iit of the valve 'sleeve lfl within the casing Aor body I'IJ, it is Ipreferred lthat these parts 4be of lthe tapered form shown, although this li's not absoiutely essential since 'said parts may be of fcylindrical form if desired.
The Valve sleeve ll is of somewhat less length thanthe length vof 4the casing Ior ibody I0, so 'that 'when ends of these parts lare aligned at lone end, preferably the smaller end, of fthe container member, the-opposite -end ol the valve sleeve i'lll will be spaced inwardly from vthe adjacent end vof the casing Yor ibo'dy I'IU, Iwhereby to provide v'a receiving socket I"2 within said'latter and larger end oi the casing or body.
'The -smaller lend of the ycontainer member is vpermanently closed by `a headed plug, the shank ll3 of which is entered Within the adjacent open 'endroftl'ie valvel sleeve "I fl while v'the yd'iam'etrically enlarged, external head M `o'f which abuts and laps the aligned extremities of the 'casing or body "Ill and valve sleeve l'l. The shank T3 of said vplug is suitably aflixed to the valve sleeve H, preferably by -a key or spline 15, so that the lexternal head il `may serve as a iinger piece' by which the valve 'sleeve may rbe rotated relative ito the casingor body yflll orpurposes subsequent- 'ly iherein referred -to.
The receiving -socket -|'2 lof the casingfor body l0 is adapted to receive a Vremovable closure means. Preferably `the receiving 'socket is internally vrscrew-threaded, and the 4closure means comprises a cap 4S having an externally screw-threaded shank 11 adapted to screw into lsaid receiving socket.
suitably :ailxed to the casing 'or body |70, to extend along the same and so as to project radially therefrom, 'is an applicator comb 1'8. AOne method of mounting said .applicator comb 18 on the body Aor casing i0, as `shown, is to vshape 'the 'back of the Acomb in the :form -of =a longitudinal tenori ,-I'9, and to provide `the=casing or body l0 `with an fexternal, longitudinallyextending mortisegroove 20 into which said tenon i9 may .be slid, thus interlocking the comb and casing ,or `-body together in `the aforesaid assembled relation.

The valve sleeve I I is provided with a pair of valve openings or slots 23-24 of major length, which, by proper rotative movement of the valve sleeve, may respectively be .brought into alignment and communication with therespective rows or groups 2I-22 of discharge openings. The lengths of said valve openings or slots 23-24 correspond to the lengths of said rows or groups 2I-22 of discharge openings, so that, when brought into alignment and communicating relation to.V the latter, a maximum quantity of treating substance which is supplied to and contained in the 'con-- tainer member, may be discharged through and from the discharge openings.

To facilitate a firm grasping of the container member by the hand of the user, the casing or body I0 is preferably provided in its exterior surface with suitably located linger seating indentations 21 at oneside thereof, and with a 0 thumb seating indentation 28 at the opposite side thereof (see Fig. 2). As the applicator comb I8 is passed through the hair, the treating pow- 5 the comb teeth, whereby, as the latter part or separate the hair filaments, the powder will readily and quickly penetrate the hair mass, and

It will be -understood that the external surface of the casing or bodyIlJ adjacent -the closure plug head I4 may be provided with suitably located valve 2,), withV which an indicator` pointer with which theclosure plug head I4 is provided (see Fig. 2)
- may cooperate for indicating closed and selected open positions of the valve sleeve.
To prepare the dispensing applicator lfor use, 5
.container member, the cap I 6 is replaced so as to close the same whereupon the valve sleeve II The dispensing applicator may be used to dissubstance, but is especially well adapted for feicient discharge of a powdered substance, such je. g. as a dry shampoo powder. Y
' -In the use of the dispensingv applicator, the
will be very uniformly distributed throughout the latter down to theI scalp or skin as the case may be. Such uniform and thorough penetration and distribution of the discharged powder through the hair mass is facilitated by the movement of the comb teeth therethrough during the combing action, since the powder in advance of the comb teeth will be quickly worked into and through the hair mass, and, as the hair laments are separated by the movement of the .comb teeth through the hair, the powder discharged behind said comb teeth will readily sift down through the interstices between separated hair filaments. Y
Not only is the dispensing applicator well adapted for supplying either a powdered or liquid hair and scalp treating substance to the human head, but is also equally well adapted for applying disinfectant, flea or cleansing powderto` the coats of .domestic animals, such as cats and dogs, or tothe coats of other hair or fur bearing animals.
It will be understood that the novel dispensing applicator of this invention may be selectively made from various materials, as e. g. from metal, wood, paper, glass, plastic material or the like. vIt will also be understood that the devicemay be made in various sizes, in whole or in part, to suit particular uses or requirements.
