Abstract

The liquid applicator of the present invention comprises an inner barrel (1) as a liquid reservoir located inside an outer barrel (2) so as to be freely shiftable in the axial direction, and a valve which, when the inner barrel is advanced against the outer barrel, is opened so as to supply the liquid to an applicator member from the inner barrel, the latter being made of a material through which the liquid can be seen, and a percussion shaft (4) comprising a window (5) allows part of the inner shaft to be seen.

Description

The present invention relates to an instrument for applying a liquid such

  a hair dye, etc. In the prior art, instruments for dyeing the hair are known in which an internal barrel forming a reservoir for dyeing is housed in an external barrel so as to be able to be shifted freely in the axial direction, and between the internal barrel and the brush. attached to the anterior end of the outer barrel a valve is interposed which can, when the inner barrel is advanced against the outer barrel, be opened so as to provide the

  brush dyeing from the inner barrel.

  However, in this type of classic instrument, one suffers from the disadvantage that one cannot be certain of

  the amount of dye remaining in the inner barrel.

  The present invention relates to a liquid applicator for convenient use in that the amount of liquid remaining in the inner barrel

can be easily estimated.

  To achieve the object exposed above, the liquid applicator of the present invention comprises an internal barrel forming a liquid reservoir, this barrel being placed in an external barrel so that it can be shifted freely in the axial direction, and between the inner barrel and an applicator element such as a brush, etc. a valve is interposed, at the front end of the outer barrel, which can, when the inner barrel is advanced against the outer barrel, be opened to supply the liquid to the applicator element from the inner barrel, the improvement being such that the inner barrel is made of a material allowing the liquid contained in the reservoir to be seen, and on the outer periphery of the rear end of the inner barrel , end which is produced so as to project outwards from the external barrel, a percussion barrel

  slide which has a window allowing to expose

part of the interior barrel.

  The present invention will be well understood

  during the following description made in connection with

  the accompanying drawings in which: Figure 1 is a perspective view of the hair dyeing instrument according to the present invention, the cap being removed; and Figure 2 is a longitudinal sectional view of the instrument, the cap being in place. The outer barrel 2 comprises a front barrel 6 screwed on its anterior end, and in the front barrel 6 a base part 7 of an application element is fixed, element on which a brush is planted 3 In the central hole of the part 7, a sponge 8 is mounted which comes into contact with the brush 3, and at the rear end of part 7, a tube 10 for supplying liquid is fixed, a stop 9 for the sponge being placed between them On the outer surface of the end

  front of the front barrel 6, a comb 11 is mounted.

  The inner barrel 1, filled with a hair dye (not shown in the drawing), is housed in the outer barrel 2 so that it can be moved freely in the axial direction, a valve being provided in the opening located at the front end of the inner barrel 1 The valve comprises a rod 12, a seat 13, a spring 14, and a support 15 On the outer periphery of the front end of the inner barrel 1, a cap 17 is screwed into which a gasket 16 is fixed The rear end of the tube 10 is inserted into the central hole of the cap 17 in watertight contact with the gasket 16, from which it follows that the rear end of the tube 10 abuts

  against the front end of the valve stem 12.

  On the outer periphery of the barrel 1, a percussion barrel 4 slides, and the embodiment is such that, if the barrel 4 is engaged in a groove 18 formed in

3 2658740

  the axial direction of the barrel 1, when this barrel 4 undergoes a rotation, the internal barrel 1 can also rotate at the same time as the percussion barrel from the opening situated at the rear end of the external barrel 2, and on the lateral face located in line with the projecting part of the barrel 4, a window 5 is provided which allows the exposure of part of the lateral face of the inner barrel 1 The inner barrel 1 has a small thickness and is made of a translucent resinous material of white color, and one can see from the outside the black dye contained in the barrel. Thus, the dye being in the inside barrel can be seen through window 5 even from outside the barrel 4 In addition, in the opening at the rear end of the barrel 2, a "breech" 19 is mounted by compression, which prevents that it was in Inner 1 does not slide backwards In addition, in the figure, the reference 20 represents a cap, the reference 21 an internal cap, the reference 22 a sealing ring and the

  reference 23 a decorative ring.

  In the present invention having the construction described above, since the inner barrel 1 is made of a material through which one can see the liquid stored in the tank, and that on the outer periphery of the end posterior of the internal barrel 1, end which projects outwards from the barrel 2, a percussion barrel 4 slides which has a window 5 allowing the interior of the barrel 1 to be seen, the amount of liquid remaining in the barrel 1 can be estimated by examining it through the window from outside the barrel 4, which greatly increases convenience

how to use the instrument.

  The present invention is not limited to the embodiments which have just been described,

  on the contrary, it is subject to modifications and

  variants which will appear to those skilled in the art.

Claims (1)
