Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic such as an oxidative hair dye, an acidic hair dye (hair manicure), a hair bleaching agent, etc., and a hair cosmetic contained therein. The present invention relates to a container with a comb that can be applied to hair.

[0002]

2. Description of the Related Art As a conventional container with a comb of this type, for example, a container having a structure as shown in FIGS. 6 (a) and 6 (b) is known. The container 41 with a comb is composed of a container body 42 for accommodating hair cosmetics, and a lid 43 attached to the container body 42. The lid 43 is provided with a comb portion 45 composed of a plurality of plate-shaped comb teeth 44, and a communication passage 46 having a fixed hole diameter and communicating with the inside of the container body 42 is provided in the comb teeth 44. I have. Further, a discharge port 47 communicating with the communication passage 46 is formed on both surfaces of the comb teeth 44. Then, the hair cosmetics stored in the container body 42 is discharged from the discharge port 47 through the communication passage 46.

[0003]

However, in the above-mentioned conventional structure, there is a possibility that the hair cosmetics may be clogged in the communication passage 46, thereby hindering use. In order to prevent the hair cosmetic from being clogged in the communication passage 46, the following two methods have been considered.

[0004] One method is to reduce the viscosity of hair cosmetics. However, if the viscosity is reduced, it becomes difficult to keep the hair cosmetics discharged from the discharge port 47 between the comb teeth 44 or the like, which causes a "drip" of the hair cosmetics dripping. In addition, depending on the type of hair cosmetics, the higher the viscosity, the higher the effect, and this method cannot fundamentally solve the above problems. For example, in the case of a hair dye for gray hair dyeing, it is desirable for the purpose to apply the hair dye completely and uniformly to the entire hair, and for that purpose, a creamy material having a high viscosity is suitable. In addition, hair cosmetics having high viscosity are less likely to damage the hair and have a high treatment effect.

[0005] Another method is to increase the cross-sectional area of the upstream communication path. Specifically, FIG.
Nozzle type applicator shown in FIG.
No. 407 discloses a foamy cosmetic application tool.

[0006] The nozzle type applicator 51 is composed of a container main body 52 for accommodating hair cosmetics, and a lid 53 attached to the container main body 52. The lid 53 has one conical nozzle 54 and the nozzle 54
A communication passage 55 is provided in the inside of which the diameter increases toward the upstream side and communicates with the inside of the container body 52. In addition, nozzle 5
A discharge port 56 that communicates with the communication path 55 is formed at the end of 4. The hair cosmetics stored in the container body 52 is discharged from the discharge port 56 through the communication path 55. However, in this case, the risk of hair cosmetics clogging the communication path 55 can be reduced. However, once the communication path 55 is clogged, there is only one communication path 55, which hinders immediate use. Was.

[0007] In the case of the foamy cosmetic applicator disclosed in JP-A-5-15407, as shown in FIG. 3 (a) of the publication, the communication path in the comb teeth is in the thickness direction of the comb teeth. Are formed such that the width increases toward the upstream side. However, since the thickness of the comb teeth is increased as the width of the communication path is increased, there is a problem that resistance during combing is increased and combing is deteriorated.

The present invention has been made by focusing on the problems existing in the prior art as described above. An object of the present invention is to provide a container with a comb that can suppress clogging of a communication path provided in a comb tooth while maintaining good comb passage.

[0009]

A comb portion made of comb teeth, wherein the comb teeth have a plate shape,
The comb teeth are arranged so that the width direction thereof is parallel to the operation direction of the comb portion during combing, and a communication passage communicating with the inside of the container body is provided in the comb teeth, and a discharge port communicating with the communication passage is further provided. A comb-shaped container formed into comb teeth and configured to discharge hair cosmetics contained in a container body from a discharge port through a communication path, wherein the thickness of the comb teeth and the interval between the comb teeth are provided. And the communication passage is formed so that the cross-sectional area increases continuously or stepwise toward the upstream side.

[0010] The container with a comb according to the second aspect of the present invention is characterized in that, in the first aspect, the hair cosmetic is an oxidative hair dye. According to a third aspect of the present invention, in the container with a comb according to the first aspect, the hair cosmetic is a two-part oxidative hair dye comprising a first agent and a second agent. The first agent and the second agent are both oil-in-water type (O
/ W type) It is to be an emulsion.

According to a fourth aspect of the present invention, there is provided the container with a comb according to the third aspect, wherein the first agent of the oxidative hair dye has a viscosity of 8,000 to 100,000 centipoise (cp).
s) and the viscosity of the second agent is 5000 centipoise (c
ps) or less.

According to a fifth aspect of the present invention, there is provided the container with a comb according to the third or fourth aspect, wherein the first agent of the oxidative hair dye contains at least 5% by weight of a higher alcohol. The gist is that it is a drop type (O / W type) emulsion.

Further, as shown in FIG. 2A, the interval between adjacent comb teeth 21 is constant in the length direction of the comb teeth 21.
The number of the comb teeth 21 constituting the comb portion 22 is preferably 5 to 10 from the viewpoint of operability.

As shown in FIG. 2A, there are six comb teeth 21 located at the center except for two comb teeth 21 (four in total) located at both ends of the comb part 22, respectively. Supply space 2
A communication passage 25 that communicates with 3 is formed. The communication path 25 extends in the length direction of the comb teeth 21, bends in the thickness direction of the comb teeth 21 at the tips of the comb teeth 21, and opens on both sides of each comb tooth 21 to form a discharge port 26. And the supply path of the hair cosmetics from the supply space 23 to the discharge port 26 is formed.

The communication passage 25 is, as shown in FIG.
Although the width is always constant in the thickness direction of the comb teeth 21,

Next, the operation of the container with comb 11 will be described. Now, the container 1 with a comb configured as described above.
When applying hair cosmetics to hair using No. 1, first,
With the lid 13 separated from the container body 12, the container body 1
2. Inject hair cosmetic into 2. Subsequently, the fitting tube 17 of the lid 13 is screwed into the opening tube 15 of the container body 12, and then the screw is advanced until the rotation of the fitting tube 17 stops, and the lid 13 is fitted to the container body 12. Let it. At this time, as shown in FIGS. 2A and 2B, the container body 12 and the lid 13 are formed by the fitting projection 24 of the lid 13 and the upper end of the opening cylinder 15.
Is closed to prevent the hair cosmetic from leaking out of the portion.

Next, the body of the container body 12 is pressed while grasping with a finger, and the hair cosmetics in the container body 12 are discharged from the discharge port 26.
The comb 22 is operated in the width direction of the comb teeth 21 while combing the hair, and the hair is combed by the comb 22. When the container body 12 is pressed, the hair cosmetics in the container body 12
3 and is discharged from the discharge port 26 through the communication passage 25. The hair cosmetic discharged from the discharge port 26 travels along the outer surface of the comb teeth 21 and is applied to the surface of the hair slidably contacted there. Furthermore, by combing the hair of the same part a plurality of times, the hair cosmetic attached to the hair is attached to the outer surface of the comb teeth 21 and the upper surface of the neck portion 20, and the attached hair cosmetic is again applied to the surface of the hair. It is applied while spreading.

As described above, according to this embodiment, the following effects are exhibited. The communication passage 25 is formed so that the cross-sectional area increases toward the upstream side, and the cross-sectional area at the upstream end of the communication passage 25 is the conventional comb shown in FIGS. 6 (a) and 6 (b). It is formed larger than the attached container 41. Therefore, the transfer of the hair cosmetic from the supply space 23 to the communication passage 25 is smooth, and the clogging of the communication passage 25 can be suppressed.

The communication passage 25 is formed so as to have a constant width in the thickness direction of the comb teeth 21 and to increase in width in the width direction of the comb teeth 21 toward the upstream side. For this reason, it is possible to form the communication passage 25 so that the cross-sectional area increases toward the upstream side with the comb teeth 21 having the same thickness as the comb teeth 44 of the conventional container 41 with combs. Therefore, the comb teeth 21 can be kept thin, and the communication path 25 can be maintained while maintaining the good comb passage as before.
Clogging can be suppressed.

The comb portion 22 is composed of ten comb teeth 21, and six of them have communication passages 25.
For this reason, even if the communication passages 25 of some of the comb teeth 21 are blocked, the hair cosmetic can be discharged through the communication passages 25 of the other comb teeth 21, which immediately hinders use. There is no fear.

By the way, a hair cosmetic is composed of a high-viscosity dye-containing composition (first agent) and an aqueous solution or aqueous emulsion of hydrogen peroxide (second agent). When a two-part hair dye having a large difference in viscosity is used, it is very difficult to mix the two into a uniform hair dye. In particular, when the first and second agents are both O / W emulsions and the two-component oxidative hair dye has the viscosity of the first agent at least 10 times the viscosity of the second agent, the two are mixed. However, the first agent remains in a granular form, which causes the communication passage 25 to be clogged.

Therefore, attempts have been made to mix the two components more uniformly by adjusting the viscosities of the first and second components to reduce the difference in viscosity between the two components. Was difficult to set to an appropriate value and was not a good solution at the moment.

However, in the container with comb 11 of the embodiment,
Even if the above hair dye is used without adjusting the viscosity, there is no possibility that the communication passage 25 is clogged. This is made possible by two factors: (1) Since the cross-sectional area of the communication passage 25 is formed so as to increase toward the upstream side, the transfer of the hair dye from the supply space 23 to the communication passage 25 is smooth. (2) Since the communication passages 25 are provided in the plurality of comb teeth 21, respectively, even if some of the communication passages 25 are clogged, the use of the communication passages 25 is not immediately hindered.

The communication passage 25 is formed so that its cross-sectional area increases continuously toward the upstream side.
The flow of the hair cosmetic in the communication passage 25 can be made smoother than in the case of expanding stepwise.

The communication passage 25 is formed so that its cross-sectional area decreases as it goes downstream, and the hole diameter D1 at the downstream end of the communication passage 25 is
It is formed to have the same size as 1. For this reason, the ability to discharge hair cosmetics from the discharge port 26 can be favorably maintained as before.

Since it is not necessary to reduce the viscosity of the hair cosmetic in order to suppress the clogging of the communication passage 25, it is possible to use a hair cosmetic having a higher viscosity (for example, a hair dye for dyeing white hair) as it is. The effect can be sufficiently exhibited.

The container 11 with a comb of the embodiment discharges the hair cosmetics in the container main body 12 from the discharge port 26,
By combing the hair with the comb portion 22, a hair cosmetic is applied to the hair. Therefore, FIG.
Compared with the nozzle type applicator 51 shown in (a) and (b), it is easier to uniformly apply the hair cosmetic to the entire hair.

By setting the size of the hole diameter D1 at the downstream end of the communication passage 25 to 0.8 to 1.9 mm, it is possible to prevent the hair cosmetics from scattering from the discharge port 26 and to exceed the required amount. Can be prevented from being discharged from the discharge port 26, and the discharge performance can be improved. Further, by setting the distance to 1.0 to 1.7 mm, the above effect can be further improved. Further, by setting the thickness to 1.2 to 1.5 mm, the above effect can be further improved.

[Table 2] From the results shown in Tables 1 and 2, when the container 11 with a comb according to the embodiment is used, even if it is a two-part oxidized hair dye or a one-part acid hair dye, it can be subjected to normal pressing. , The hair cosmetics could be easily discharged and the operability was good. No clogging of the communication passage 25 was observed except in the case of the oxidative hair dye C, in which the viscosity difference between the first agent and the second agent was about 25: 1 and the viscosity difference was the largest. Also, the clogging in this case was not a degree that would hinder use.

On the other hand, when the oxidized hair dyes A to C are applied to the hair using the conventional container 41 with a comb, the container body 42 is strongly pressed to discharge the oxidized hair dyes A to C. It was shown that operability was somewhat difficult. It was also shown that the greater the difference between the viscosities of the first agent and the second agent, the more easily the communication passage 46 was clogged.
In the case of acidic hair dyes X to Z, the viscosity is 100000 cps
In the case of the acidic hair dye Z having a high viscosity, it was necessary to strongly press the container body 42 in order to discharge the dye, and it was shown that the operability was somewhat difficult when the viscosity was high. It was also shown that the higher the viscosity, the more likely the communication passage 46 is to be clogged.

When the hair dyes A to C are applied to the hair using the nozzle type applicator 51, the communication passage 55
It has been shown that the stuffing can interfere with use. In the case of the acidic hair dyes X to Z, no clogging was observed in the communication passage 55, but it was necessary to strongly press the container main body 52 in order to discharge, and it was shown that the operability was somewhat difficult.

The above embodiment can be modified as follows. As shown in FIG. 4A, the communication passage 25 is
Although the width is always constant in the thickness direction of FIG.
As shown in (b), in the width direction of the comb teeth 21, the comb teeth 21 are formed so as to gradually increase in width toward the upstream side. Even in the case of such a configuration, substantially the same effects as in the embodiment can be obtained.

The shape of the comb teeth 21 is changed to an arbitrary plate shape instead of the substantially triangular plate shape of the embodiment. For example, as shown in FIGS. 4A and 4B, a square plate portion 21a and a substantially triangular plate portion 21 provided at the tip of the square plate portion 21a.
b. With such a configuration, more hair cosmetics can be held between the comb teeth 21 than in the case of the embodiment, and the hair cosmetics can be uniformly and promptly applied from the root to the tip of the hair.

In the container with comb 11 of the embodiment, the lid 13 including the comb teeth 21 is formed integrally, but at least a part of the comb teeth 21 is formed separately from the lid 13. You may. That is, as shown in FIGS. 5 (a) and 5 (b), for example, in the comb-equipped container 11 provided with six comb teeth 21, four comb teeth 21 located at the center except for two on both sides.
May be formed separately from the lid 13 and assembled after molding to be integrally formed.

The thickness of the comb teeth 21 only needs to be substantially constant in the longitudinal direction of the comb teeth 21. If the thickness of the comb teeth 21 does not deteriorate, for example, as shown in FIG. You may comprise so that thickness may increase a little as it goes.

The spacing between the comb teeth 21 may be substantially constant in the longitudinal direction of the comb teeth 21. If the comb passing is not deteriorated, for example, as shown in FIG. You may comprise so that an interval may become slightly small as it goes.

The thickness of the comb teeth 21 may be different for each of the comb teeth 21. The interval between the comb teeth 21 may be different for each of the comb teeth 21. The comb portion 22 of the embodiment is of a type in which the comb teeth 21 extend upward (vertical comb), but may be changed to a comb portion in which the comb teeth 21 extend horizontally (horizontal comb). The number of comb teeth 21 constituting the comb portion is preferably 10 to 16 from the viewpoint of operability.

In the embodiment, a so-called squeeze-type comb-shaped container 11 in which the hair cosmetic is discharged by crushing by hand.
However, a so-called aerosol type container with a comb may be used. That is, the hair cosmetic in a pressurized state may be enclosed in a container having pressure resistance, and the valve may be opened by pressing a push button to eject the hair cosmetic.

The container body 12 of the embodiment is changed to a double container. That is, this double container is composed of an inner container and an outer container both having flexibility, and both these containers are formed so as to be commonly opened.
Hair cosmetics are stored only in the inner container. Further, the outer container is provided with a check valve for inflow of air, so that air flows into the space between the inner container and the outer container via the check valve.

In the case of such a configuration, the inner container is crushed by pressing the outer container, and the hair cosmetic is discharged. Then, when the pressing is stopped, air flows from the outside through the check valve into the space between the inner container and the outer container, and the outer container returns to its original shape, while the inner container maintains the collapsed state. Can be. For this reason, the inner container shrinks with each use, and the hair cosmetic can be completely used up to the end. In addition, the inner container and the outer container are configured to be separable,
At least the outer container may be made reusable.

Next, the technical ideas that can be grasped from the above embodiment will be described below. The communication passage is formed so as to have a constant width in the thickness direction of the comb teeth, and is formed to increase continuously or stepwise in the width direction of the comb teeth toward the upstream side. The container with a comb according to any one of claims 1 to 5, wherein the communication passage is configured so that a cross-sectional area increases toward the upstream side.

In the case of such a configuration, it is possible to configure the communication path such that the cross-sectional area increases toward the upstream side without increasing the thickness of the comb teeth. Therefore, clogging of the communication path provided in the comb teeth can be suppressed while maintaining good combing.

The container with a comb according to any one of claims 1 to 5, wherein a cross-sectional shape of the communication passage is formed to be circular, elliptical, or substantially elliptical. With this configuration,
The flow of the hair cosmetic in the communication passage can be made smooth.
