LIQUID APPLICATOR
Abstract
A liquid applicator comprising an inner shaft (1) as a
reservoir of a liquid housed in the interior of an outer shaft
(2) so that it can be freely axially shifted and a valve
interposed rendering it possible that when said inner shaft is
advanced against said outer shaft said valve is opened so as to
supply the liquid to an applying member from said inner shaft,
said inner shaft being formed of a material through which the
liquid can be seen, and a knock shaft (4) provided with a
window hole (5) admitting exposure of a portion of the inner
shaft being slipped on the outer peripheral portion of the rear
end of said inner shaft protruding outward from said outer
shaft.

OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
In a liquid applicator wherein an inner shaft (1)
reservoiring a liquid therein is housed in the interior of an

LIQUID APPLICATOR
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to an instrument for
applying a liquid such as a hair dye liquor, or the like.
Prior Art
Heretofore, there are well known hair dyeing
instruments wherein an inner shaft reservoiring a hair dye
liquor therein is housed in the interior of an outer shaft so
that it can be freely shifted in the axial direction, and
between said inner shaft and the brush fixed at the front end
of said outer shaft a valve is interposed rendering it possible
that when said inner shaft is advanced against said outer shaft
said valve is opened so as to supply the hair dye liquor to the
brush from said inner shaft. In such conventional hair dyeing
instruments, however, it has been inconvenient that the
residual quantity of the hair dye liquor resrvoired in the
interior of the inner shaft cannot be ascertained.
The object of the present invention is to provide a
liquid applicator which is convenient for use in that the
residual quantity of the liquid reservoired in the interior of
the inner shaft can be readily ascertained.
(Means for Solving the Problems)
SUMMARY OF THE INVENTION
In order to achieve the above-described object, in the
liquid applicator of the present invention it is contemplated
that in a liquid applicator wherein an inner shaft reservoiring
a liquid therein is housed in the interior of an outer shaft so

that it can be freely shifted in the axial direction, and
between said inner shaft and the applying member such as brush,
or the like, fixed at the front end of said outer shaft a valve
is interposed rendering it possible that when said inner shaft
is advanced against said outer shaft said valve is opened so as
to supply the liquid to the applying member from said inner
snaft, an improvement is made in that said inner shaft is
formed of a material through which the liquid reservoired
therein can be seen, and on the outer peripheral portion of the
rear end of said inner shaft, of which rear end is made so as
to protrude outward from said outer shaft, is slipped a knock
shaft which is provided with a window hole admitting exposure
of a portion of the inner shaft.
BRIEF DESCRIPTION OF THE DRAWINGS

instrument according to the present invention in an uncapped
state, and

a capped state.
DETAILED DESCRIPTION AND THE PREFERRED EMBODIMENT
Referring to the drawings illustrated a hair dyelng
instrument, the present invention will be explained more detail
below.
The outer shaft 2 has a front shaft 6 screwed onto
the front end thereof, and in the interior of said front shaft
6 is fixed the basal part 7 of the applying member on which
brush 3 has been planted. In the cen~tral hole o~ said basal
part 7 is fitted sponge 8 which comes in contact with brush 3,

and at the rear of said basal part 7 ~s fixed a liquid delivery
tube 10, with the stopper 9 for the sponge being disposed
therebetween. On the outer surface portion of the front end of
said front shaft 6 is mounted a comb 11.
The inner shaft 1 within which a hair dye li~uox (not
shown in the drawing) has been filled up is housed within the
outer shaft 2 so that it can be freely shifted in the axial
direction, with a valve being provided in the opening at the
front end of said inner shaft 1. Said valve comprises valve
stem 12, valve seat 13, valve spring 14, and spring bearing 15.
Onto the outer peripheral portion of the front end of said
inner shaft 1 is screwed a cap 17 which has packing 16 fixed
therein. The rear end of the above-described liquid delivery
tube 10 is inserted through the central hole of said cap 17 in
a state coming in watertight contact with the packing 16,
whereby said rear end of the li~uid delivery tube 10 abuts
against the front end of the valve stem 12. On the outer
peripheral portion of said inner shaft 1 is slipped the knock
shaft 4, and it is designed in such a way that if the knock
shaft 4 is engaged with a groove 18 provided in the axi.al
direction of said inner shaft 1, when the knock shaft 4 is
given a rotating operation, said inner shaft 1 also can rotate
integrally with the knock shaft. Both the rear ends of the
inner shaft 1 and the knock shaft 4 protrude rearward from the
opening at the rear end of the outer shaft 2, and on the side
face at the protruding portion of said knock shaft 4 is
provided a window hole 5 which admits exposure of portion of
the side face of the inner shaft 1. The inner shaft 1 is of

thin make formed of a milk white translucent resinous material,
and the black hair dye liquor reservoired therein can be seen
therethrough from the outside. Thus, the hair dye liquor in
the inner shaft 1 can seen through the window hole 5 even from
the outside of the knock shaft 4. Further, in the opening at
the rear end of the outer shaft 2 is fitted by pressing a
breechblock 19 which prevents the inner shaft 1 from slipping
rearward. In addition, in the drawing, 20 is a cap, 21 is an
inner cap, 22 is a seal ring, and 23 is an ornamental ring.
The present invention is constructed as described
above. Since in the present invention the inner shaft 1 is
formed of a material through which the liquid reservoired
therein can be seen, and on the outer peripheral portion of the
rear end of said inner shaft 1, which rear end has been made so
as to protrude outward from said outer shaft 2, is slipped a
knock shaft 4 which is provided with a window hole 5 admitting
exposure of portion of the inner shaft 1, it has such an effect
that the residual quantity of the liquid in the interior of the
inner shaft 1 can be ascertained by seeing it through said
window hole even from the outside of the knock shaft 4 and thus
the convenience for use is greatly improved.
