4 Claims. (Cl. 132-116) The present invention relates to a new and improved method and apparatus for dyeing hair. More particu-' larly, the present invention relates to a new and improved method and apparatus for hair dyeing wherein the hair dyeing substance is activated immediately preceding the application of the dye to the hair.

Most hair dyeing substances in use today are obtained by mixing a latently dyeing substance with an activating substance. For example, an oxidation dye is obtained by mixing an oxidizing agent with coloring matter or a coloring pigment. The coloring action of the oxidation dye occurs only when the coloring pigment has been mixed with the oxidizing agent. The effectiveness of the oxidation dye lasts only a short time after the activating oxidation agent has been added. Therefore, the effective coloring action of the oxidation dye becomes weaker with time.

Accordingly, in practice today the latently dyeing substance and the activating substance are kept in separate containers. The mixture is made by mixing the two substances in a common container in the desired proportion. The oxidation reaction between the coloring pigment and the oxidizing agent starts when these two substances come in contact with each other so that it is apparent that this reaction starts before the mixture is actually applied to the hair. It is apparent, therefore, that the effectiveness of the activated dye becomes smaller and smaller as the activated dye is being applied to the hair. Since application of a coloring dye to a complete head of hair takes a substantial amount of time, the oxidation reaction of the mixture in the common container which continues during this time greatly decreases the strength of the coloring dye.

There are several other disadvantages which are present when the above described conventional methods of hair dyeing are used. 'For example, oxidation reaction causes the mixture to develop heat. Foam develops over the surface of the mixture and therefore interferes with the proper application of the dye to the hair. A gaseous release occurs and thereby produces an undesired initial pressure if the mixing of the two substances takes place in a closed instead of an open container.

Accordingly, it is one of the objects of the present invention to overcome the above described disadvantages.

Another object of the present invention is to provide a new apparatus for the dyeing of hair.

A further object of the present invention is to provide a new apparatus for dyeing hair wherein the dye is activated as the mixture is being applied to the hair.

Still another object of the present invention is to provide a new and improved apparatus for dyeing hair, which apparatus can be used with several different types of dye applicators.

Another object of the present invention is to provide 7 compressible container means for a latently dyeing substance, compressible container means for an activating substance for the latently dyeing substance, a mixing container connected to the container for the latently dyeing substance and the container for the activating substance for receiving the substances from the same, whenever desired, creating in the mixing containing an activated dyeing substance, means for regulating the relative pressures that can be applied to said compressible container means and dye applicator means connected to and communicating with the mixing container for applying the thus-obtained activated dyeing substance to the hair, enabling thereby, during the period of application of the activated dyeing substance, continuous creation of the same during such period of application in the mixing container immediately preceding application thereof.

The novel features which are considered as characteristie for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings, in which:

Fig. 1 is a plan view of a portion of apparatus constructed in accordance with the principles of the present invention, to which a dye applicator may be added;

Fig. 2 is a perspective view of the apparatus shown in Fig. 1 with a comb dye applicator applied;

Fig. 3 is a perspective view of the apparatus shown in Fig. 1 showing a different dye applicator connected to the apparatus;

Fig. 4 is a plan view of another embodiment incorporating the principles of the present invention;

Fig. 5 is a sectional view of Fig. 4 taken on the line II II.

Fig. 6 is a plan view of another embodiment of the present invention;

Fig. 7 is an elevational view of a portion of the apparatus constructed in accordance with the principles of the present invention; and

Fig. 8 is an elevational view of another-embodiment of the present invention.

Referring now to Fig. 1, a compressible container 8 is shown in which a latently dyeing substance may be stored. A similar compressible container 9 is provided for an activating substance for the latently dyeing substance stored in the container 8. Threadedly connected to the container 8 is a conduit 1 at its end 5 by means of a cap 7. The other end 3 of the conduit 1 has a plurality of openings 11.

A similar conduit 2 is threadedly connected to the container 9 atits end 6. At the other end 4 of the conduit 2 a plurality of openings 10 is provided. The respective openings 10 and 11 are preferably provided to correspond with each other. In operation, the latently dyeing substance in the container 8 and the activating substance in the container 9 may be simultaneously ejected from the respective- openings 11 and 10 by compressing containers 8 and 9.

In Fig. 2 a comb 13 is shown connected to the ends 3 and 4 of the conduits 1 and 2, respectively. The comb 13 has a rear portion 14 with a mixing container 12 formed therein. The mixing container 12 is shaped to cooperate with the ends 3 and 4 of the conduits 1 and 2. A slot 15 is provided adjacent the teeth of the comb 13 to permit the mixture formed in the mixing container 12 to flow out alongside the teeth of the comb 13.

In operation, it can be seen that as the comb is used on the hair, activated dye may be applied to the hair merely by compressing the containers 8 and 9. The

latently dyeing substance in the container 8 will flow Patented Jan. 14, 1958 amazes E @9981? the bale 1. and the activatin substance from the container 9 will flow out. through the holes 10.
