Description

The present invention relates to a hair dye applicator, and more particularly to a hair dye applicator that can apply a hair dye without staining hands and scalp when applying the hair dye.

Conventionally, a storage unit for liquid hair dye as an application for hair dye, an application unit for applying hair dye delivered from the storage unit, and a comb body around the application unit so that the application unit does not directly contact the scalp An upright hair dye applicator has been proposed (Patent Documents 1 to 5). These hair dye applicators are integrated with the storage unit, and it is possible to store the hair dye and control the amount of application, but it is difficult to dispose of used containers, and the application unit can be dried and prevented when not in use for a long time. There is a problem with fungi, and there is also a problem with the convenience of adding and replacing hair dyes.
In addition to these, there has been proposed an applicator for storing an impregnated body containing a hair dye in advance and a comb body in contact with each other, and pulling out only the comb body during use (Patent Document). 6). According to this method, the hair dye can be easily supplied and the application work can be easily performed, but there is a problem that the amount of the hair dye that can be applied at one time is small and the fingers and scalp are easily stained. is there.
In parallel with the above-described conventional technology, an applicator that is separated from the tip of the comb body and an applicator impregnated with the hair dye near the base is disposed, and discharge and delivery of the hair dye are omitted, and an applicator that can be applied easily. It has been developed (Patent Documents 7 to 10). In these applications, although one of the features is that the fingers are not easily soiled during application, the application part is actually a mechanism that is easy to come into contact with parts other than the part to be applied (that is, hair). In addition, it is difficult to avoid contamination of the part other than the coated part by the hair dye.
In addition to the technique of the applicator that can be applied simply, the part corresponding to the application part is surrounded by comb teeth or brush hair, and the structure is such that contact with other parts than the target application part is unlikely to occur. (Patent Documents 11 to 13). In these applications, since the portion corresponding to the application body is surrounded by many combs and brushed flocks, the application body does not reach the hair, or the application area is small, so it can contact a wide range of hair. In addition, there is a problem that application cannot be performed with a sufficient application amount, and there is a problem that, when replacing the application part to remove it, flocking of the comb body and brush obstructs the replacement. Furthermore, these applicators do not take into account the flocking of combs and brushes, the spacing between application portions, and the ease of application, and cannot be said to be easily applied by the user.

In consideration of the above-mentioned problems, the present invention can apply a large amount of hair dye with a large area in a small number of times despite a simple configuration, and hardly contaminates fingers and the like other than the part to be applied. It aims at providing a hair dye applicator. It is another object of the present invention to provide a structure that can easily replace an application part impregnated with a hair dye and does not contaminate fingers and the like.

In this application, the direction of the tip of the comb body of the applicator is “upward”, and the direction of the base of the applicator, that is, the portion where the applicator and the applicator main body are fixed, is “downward”.

In order to solve the above-mentioned problems, the present invention provides, as a hair dye applicator, (1) a series of comb bodies that are impregnated with a hair dye, a flexible columnar application body is fixed to the base, and extends above the application body. However, it has a wall portion provided on an edge of one side, is provided at the base portion so as to face at least two side surfaces of the columnar application body, and is spaced apart from the application body by 1 mm or more and 7 mm or less. Two wall portions are provided, and the comb teeth tips of the series of comb bodies share one virtual surface, and the distance between the virtual surface shared by the comb teeth tips and the upper end of the application body is 1 mm or more and 10 mm or less. Adopt a hair dye applicator characterized by being.
In this applicator, since the wall surface including the comb extending upward from the applicator portion is surrounded by at least two opposing surfaces, fingers and the like are not easily contaminated in addition to the application to the hair. In addition, the distance between the tip of the comb teeth and the upper end of the application body and the distance between the application body and the wall surface having the comb teeth are adjusted to make the application body flexible. It can be applied depending on the area.

Next, (2) the application body is inserted into a box having an opening on at least the application surface side, the box is fixed to the base, and is further covered by a lid that fits the box. The hair dye applicator described in (1), which is obtained, is employed.
In this applicator, the lower part of the applicator is covered with a box, and a part of the cover can enter the gap between the applicator and the wall, so that the cover covers the box. Since the upper part of the coated body is covered by the body, volatilization of the solvent of the hair coloring agent can be delayed or prevented when not in use.

Furthermore, (3) The hair dye applicator according to (1) is employed, wherein the upper side surface of the columnar application body is formed of a flat surface or a curved surface.
In this applicator, the shape of the applicator that is optimal for application can be selected as appropriate in accordance with the shape of the surface shared by the tips of the combs.

(4) The hair dye applicator according to (2), wherein the box and the base are detachable.
In this applicator, the box and the base body can be removed, so that it can be removed when the hair dye impregnated in the application body is used up. And the box in which the new application body is inserted can also be mounted | worn. Moreover, when removing before using up, it becomes possible to hold | maintain an unused hair dye until the next use by attaching a cover body as said (2).

(5) A hair dye applicator cartridge that is removable from the hair dye applicator according to (4), wherein the entire surface of the applicator body is covered with the box and the lid.
Here, a structure composed of an applied body, a box, and a lid is handled as a cartridge body of a hair dye, and can be appropriately replaced depending on the use situation. Moreover, the base body provided with the comb body can be used as a hair dye applicator any number of times by exchanging the cartridge body.

(6) Further, the hair dye applicator cartridge according to (5), which is sealed with a sealing body, is employed.
By this sealing, the storage of the hair dye in the cartridge body when not in use is made more complete.

Since this invention is comprised as mentioned above, there exists the following effect.
The coated body impregnated with the hair dye and the comb body have an appropriate height difference (1 mm or more and 10 mm or less) and an appropriate arrangement interval (1 mm or more and 7 mm or less), and the comb body is the coated body. Since the hair dye is disposed so as to be sandwiched between at least two surfaces facing each other, the hair dye can be applied in a wide and large amount. When the protrusion of the comb body is less than 1 mm compared to the application body, the application body may come into contact with the scalp or the like, and the comb body cannot crawl and align the hair, so that a good application cannot be performed. When the protrusion of the comb body exceeds 10 mm, the hair and the application body do not come into contact with each other and application is impossible. When the interval between the arrangement of the application body and the comb body becomes narrow, that is, when the interval is less than 1 mm, the comb body comes into contact with the application body before combing and aligning the hair. The hair dye cannot be applied. Moreover, when the arrangement | positioning space | interval exceeds 7 mm, the hair which was combed and arranged again is disturb | confused again and a uniform application | coating cannot be performed (especially in the case of short hair).
Further, the virtual plane shared by a series of combs includes a plane or a side surface of a cylinder having a center line far above the base. A spherical surface having a center far above the substrate is preferable. In particular, the applicator can come into contact with the user's hair at a large portion as long as it is a curved surface that matches the spherical surface of the user's individual head. However, even if the virtual surface is a flat surface, it can be suitably used depending on the portion to be coated. For example, when the surface to be shared is a flat surface, such as when partial dyeing is desired, it is easy for the user to grasp the portion that can be applied, and partial application can be performed easily.
Here, by making the application body a flexible porous body, the application portion can be brought into contact with the hair at a larger portion, and more hair dye can be applied. The specific hardness of the porous body, that is, the measured value of JIS K6253 type A durometer is 60 or less, preferably 20 or more and 50 or less. If the value exceeds 60, even if it hits hair or the like, the original shape is maintained, the contact portion does not expand, and the amount of coating cannot be increased.

The application body is inserted into the box, fixed to the base, and further covered with a lid, so that when the application operation is temporarily interrupted (for example, several hours), the solvent from the hair dye, etc. Evaporation can be prevented or suppressed. As described above, since there is a gap between the wall portion provided with a series of comb teeth and the application portion, it is possible to cover the lid body with a cover extending to the lower end of the application portion. Here, when the lid can be fitted to the box and the application part can be sealed, evaporation of the solvent and the like can be completely prevented, but evaporation can be largely suppressed even when the cover structure is not used.

Furthermore, by making this application part, box, and lid as a single cartridge body detachable from the substrate, when the application operation is interrupted or when the hair dye impregnated in the application body has been used, This makes it easy to replace and the base part can be used many times. In addition to the viewpoint of preventing waste of resources, the reason why the base should be continuously used is further increased as long as the base is adapted to each individual user.
If this cartridge body can be further sealed with a sealing body, it can be stored for a long period of time when not in use and not in use, resulting in a cartridge body that is even better stored, and by replacing the cartridge body one after another It can be used for a long time.

And according to the state of the part which should apply | coat the upper side surface of a columnar application part, it can be made into a plane or a curved surface. Examples of the curved surface include a kamaboko shape and a dome shape.
