Abstract

Disclosed is a device for applying hair dye liquid to hair from a variety of starting levels of the hair. The device includes a storage section (1) storing liquid to be dispensed, a piston (3) dispensing the liquid in a measured amount, and a cap having a base (8) provided with a plurality of hollow teeth (6) used for dyeing hair roots and a plurality of openings (7) used for dyeing the hair along the entire length of the hair. The base (8) is concave so that it corresponds to the shape of the skull, and the cap (5) is provided with fixing means (2) which allows the cap (5) provided with the hollow teeth (6) and the openings (7) to be replaceable.

Description

  The present invention relates to an apparatus for applying hair dyeing liquids at various levels, in particular at the level of the hair root and / or along the entire length.

  The most similar prior art is described in the following patents and the like.

  Patent Document 1 describes a related apparatus including a large number of teeth that function as comb teeth and a large number of holes for distributing the dyeing composition disposed on a flat surface.

U.S. Pat. No. 6,057,056 describes a related device that is arranged on a flat surface and has a number of teeth and holes for dispensing the dyeing composition.
French Patent Application Publication No. 2850545 (FR2850545) International Publication No. 98/51183 (WO98 / 51183)

  The above devices are inconvenient in the following points.

  The former only dispenses the composition at the edge level of the tooth, i.e. at the level of the hair, and the application surface is puffy because the support surface is flat. Also, the means for moving the piston is of the screw and nut type, and the accuracy is low and both hands must be used. Furthermore, the dispensing port arranged at the end of the tooth prevents the good distribution of the liquid.

  The latter distributes the composition at the end level of the tooth, so that at the level of the support base, the surface of the support is flat and the application surface is bulging. Further, since the piston moving means is electrical, a battery is required. Furthermore, the dispensing port arranged at the end of the tooth prevents the good distribution of the liquid.

  The present invention realizes an apparatus that eliminates the inconvenience described above.

  To this end, the present invention is an apparatus used to apply hair dyeing liquids at various levels, a reservoir containing the liquid to be dispensed, a piston for dispensing the measured amount, It comprises a number of hollow teeth used to dye the root of the hair and / or a cap with a base with a number of holes for dyeing the full length of the hair.

  The device is recessed so that the base conforms to the shape of the skull, to provide a better distribution of the staining solution and to have a fixing means that allows the cap to be replaced, It is characterized in that a cap having a hole can be replaced and used.

In addition, the device
An assembly composed of a trigger, a shaft, a travel plate fitted with a spring, and a brake plate fitted with a spring, which can act on the piston to supply a measured amount of liquid Including
-The hollow teeth distribute liquid through the lateral openings.

The device shown in the drawing is used to apply hair dye at various levels, basically,
A reservoir 1 containing the liquid to be dispensed;
A piston 3 that disperses the measured quantity;
-Comprises a cap 5 with a base 8 with a number of hollow teeth for dyeing the root of the hair and / or a number of holes 7 for dyeing the full length of the hair.

According to the basic features of the invention:
The base 8 conforms to the shape of the skull and is recessed to better distribute the liquid, preferably cylindrically;
The cap 5 has a hollow tooth 6 or has a hole 7 or a cap 5 having both a hollow tooth and a hole, so that the cap 5 is threaded or otherwise replaceable A type of attachment means 2 is provided.

According to another feature of the invention, the device comprises:
A piston 9 comprising a trigger 9 belonging to the body of the reservoir 1, a shaft 10, a travel plate 4 fitted with a spring 11 and a brake plate 12 fitted with a spring 13, so as to supply a measured amount of liquid; Set that can act on 3;
A button 14 that can release the brake plate 12 and a return spring 15 that can lift the piston in the reservoir 1 again;
-A stepped shaft 16 formed integrally with the piston 3 and guided by a support 17 integral with the body of the reservoir 1 so that the piston can be maintained in the same orientation during its linear movement; The support 17 also acts as an element for guiding the shaft 10 of the piston;
The hollow tooth 6 easily distributes the liquid through the side opening 6A;
The hollow teeth 6 can have various lengths to better distribute along the entire length of the hair.

  The passage of the cap with or without the distribution hole can alternatively be realized by a device that covers the hole if necessary. Finally, the device has the advantage that it can function as a reservoir that can be discarded after use or cleaned and reused.

The invention is not limited to the embodiments described above, and does not depart from the scope of the invention, in particular:-material properties, forms and dimensions of the elements constituting the device according to the invention;
The means acting on the piston and the type of base used for the cap;
-The number and arrangement of teeth and holes associated with each cap;
-It must be understood that this is an alternative to the type of staining solution or lotion to be used (eg treatment lotion).

  The present invention relates to an apparatus for applying a hair dyeing liquid at various levels, particularly at the hair root level and / or along the entire length, and is useful as a hair dyeing liquid applying apparatus.
