LIQUID HAIR COSMETIC APPLICATOR BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to an instrument for applying a liquid hair cosmetic such as a hair dye liquor, or the like, provided with a freely attachable and detachable comb body. Prior Art

Heretofore, there are prior-known hair dyeing instruments provided with a freely attachable and detachable comb dody, but in these dyeing instruments, it is designed that in the case where the comb body is detached, the teeth portion of the comb body is drawn out by picking up between the fingertips.

In the above described conventional hair dyeing instruments it was found to be troublesome in that since in the case where the comb body is detached, the hair dye liquor, or the like, adhered to the teeth portion of the comb body sticks to the fingertips, the fingertips must be washed. Furthermore, tliere were also problems such that when the teeth portion is put between the fingers the teeth break, or the teeth portion cannot easily be drawn out because of their bending, and so on. SUMMARY OF THE INVENTION

The object of the present invention is to provide a liquid hair cosmetic applicator comprising a comb body mounted in a freely attachable and detachable manner to a front shaft protrusively provided with an applying member comprising a brush and others, and a teeth portion of the comb body being 1 1 arranged parallel to said applying member, characteriz-ed in that on the outer surface of a portion of the comb body engaging with the front shaft there are provided protruding ribs lying in the direction substantially perpendicular to the direction drawing the comb body out of the front shaft.

In a liquid hair cosmetic applicator according to the present invention, hair dye liquor or the like never adheres to the fingertips, and there are found no bad effects such as the breakage of the teeth of the comb body, etc.

DETAILED DESCRIPTION AND THE PREFERRED EMBODIMENTS

With reference to the drawing the example of the present invention will be explained below.

The outer shaft 1 has a front shaft 2 screwed onto the front end thereof, and in the interior of said front shaft 2 is fixed the basal part 4 of the applying me.mber on which a brush 3 has been planted. In the central hole of said basal part 4 1 is fitted a liquid impregnated body 5 such as sponge, etc. which comes in contact with the brush 3, and at the rear of the basal part 4 is fixed a liquid delivery tube 7 with the stopper 6 for the liquid impregnated body being disposed therebetween. At the front end 2a of the front shaft 2 Is mounted a comb body 8. The inner shaft 9 within which a liquid hair cosmetic (not shown in the figure) such as a hair dye liquor has been contained is housed in the interior of the outer shaft 1 so that it can be freely shifted in the axial direction, with a valve-10 being provided in the opening at the front of said inner shaft 9. Said valve 10 comprises a stem 1!, a valve seat 12, a valv spring 13, and a spring bearing 14. Onto the outer peripheral portion of the front end of said inner shaft 9 is screwed a cap 17 which has packing 15 fixed therein. The rear end of the above described liquid delivery tube 7 is inserted through the central hole of said cap 16 in a state coming in watertight contact with the packing 15, whereby said rear end of-,-the liquid delivery tube 7 abuts against the front end of the valve stem 11. On the outer peripheral portion at the rear end of said inner shaft 9 is slipped the knock shaft 17, and it is designed in such a way that if the knock shaft 17 is engaged with a groove 18 provided in the axial direction of said inner shaft 9 when the knock shaft 17 is given a rotating operation, said inner shaft 9 also can rotate integrally with the knock shaft. Further, in the opening at the rear end of said outer shaft 1 is fitted by pressing a breechblock 19 which prevents said inner shaft 9 from slipping rearward. The head portion 20 at a position somewhat behind the cap 16 in said inner shaft 9 has a flat surface on both sides, thus the cross-section along the direction perpendicular to the axial line being almost of the shape of a "koban" (a Jaspanese gold coin used in former times). on the inner surface of the outer shaft 1 is protrusively formed a controling wall 22 having a through hole 21 whose cross-section is almost simlar to, but slightly larger than, that of the above described head portion 20 of the inner shaft 9 in shape, and together with this there is also formed a stopper 24 having ribs 23 which have been protrusively formed similarly on the inner surface in the direction of from one end of the edge of said controling wall 22 to the back, said stopper 24 being fixed on the inner surface of the outer shaft 1 so that said controling wall 22 can be situated in front of the head portion 20 of the inner shaft 9 which is in an unknocked sate.

When the inner shaft 9 is rotated integrally with the knock shaft 17 by giving a rotating operation to said knock shaft 17 so that the contour of the head portion 20 of the inner shaft.9 can enter the contour of the through hole 21 of the controling wall 22, if the knock shaft 17 is pressed forward, the head portion 20 passes through the through hole 21 allowing the inner shaft 9 to advance, but as the valve stem 11 abutting against the liquid delivery tube 7 cannot advance, it results that the valve stem 11 retreats relative to the valve seat 12, and thus the valve 10 is opened rendering it possible that the liquid hair cosmetic discharged from the inner shaft 9 is supplied to the brush 3 by passing through the liquid delivery tube 7 and liquid impregnated body 5. Furthermore, in the case where the inner shaft 9 has been rotated, it is contemplated that the positioning may be made so that the contour of the head portion 20 can just fit in the contour of the through hole 21 in such a state that the stepped portions (not shown in the figure) provided at the end positions of the flat portions of the side faces of the head portion 20 are engaged with the above described ribs 23 of the stopper 24. It is also contemplated that when the knock pressure is released so as to retreat the inner shaft 9 by the restoring force of the yalve.spring 13 and the inner shaft 9 is rotated in the reverse direction in such a state that the head portion 20 is positioned in the rear of the through hole 21, the contour of the head portion 20 overruns the contour of the through hole 21, so that even tho ugh the inner shaft 9 may advance by the force of inertia due to its.own weight, it cannot advance, b;eing hampered by the controlling wall 22. Accordingly, if s.uch.a state is assured when not in use, the unwilling discharge of the liquid hair cosmetic due to the advancement of the inner shaft 9 can be prevented.

Now,"referring to the front end 2a of the above described front shaft 2, the shape of its cross-section is almost rectangular as shown in Fig. 7, and at both ends on the flat side face 2b including one of the long sides of the rectangle are protrusively provided outwardly hooked ribs 2c. On the other hand, the comb body 8 which is mounted to the front end 2a of the front shaft 2 comprises the teeth portion 8a consisting of a plurality of teeth arranged in one plane and the engaging portion 8b forming an integral part of said teeth portion 8a as shown in Pigs. 2 through 7, and further, said engaging portion 8b comprises the basal part 8c in the form of a curved plate and the side face plate portions 8d on both sides thereof. While at the front end of said side face plate portion 8d are provided inwardly hooking pieces 8e capable of engagement with the hooked ribs 2c provided at the front end 2a of the above described front shaft, on the outer surface of the basal part 8c are provided ribs lying in the direction substantially perpendicular to the axial direction. The comb body 8 is mounted to the front shaft 2 in a freely attachable and detachable manner in such a state that the engaging portion Cb thereof is parallel to the side face portion 2b of the front _end 2a of the front shaft 2.

Furthermore, the present invention is devised so as to put on the outer peripheral portion of the front shaft 2 a cap '(not shown in the figure) covering the brush 3 and the comb body 8, and in Fig. 1, 25 and 26 indicate a seal ring and an ornamental ring, respectively.
