Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an agent applying tool used for applying, for example, a hair styling agent or a hair dye to hair.

[0002]

In order to simplify the operation of applying an agent such as a hairdressing agent to hair, there is an agent application tool in which a container filled with the agent and a comb are integrated.
The agent applying tool can directly supply the agent to the surface of the comb teeth by pressing the container part also serving as the handle.

[0003] However, such an agent application tool has the following disadvantages. First, when the agent is discharged, the container portion is crushed by that amount, so that the appearance gradually deteriorates. Second, many agents applied to the hair have a high viscosity, and a certain amount remains attached to the inner wall. For this reason,
The medicine cannot be completely used up. Japanese Patent Application Laid-Open No. 6-100057 discloses a laminated container provided with an outer container made of elastic plastic and a bag-shaped inner container, and provided with a check valve for air inflow at the bottom of the outer container. It is shown. The above problem can be solved by using this container.

[0004] However, it is very difficult to actually combine it with an agent application tool due to cost problems.
That is, generally, unlike the comb portion, the container portion of the agent application tool is replaced with a new one filled with the agent as soon as the container is emptied. That is, the container portion is premised on being disposable.
However, since the above-mentioned laminated container is an expensive one provided with a check valve, it cannot be easily disposable.

[0005] Accordingly, the problem to be solved by the present invention is to discharge the agent without deteriorating its appearance, to use the agent almost completely, and to inexpensively fill the container portion with the agent. It is an object of the present invention to provide an economical agent application tool which can be replaced.

[0006]

An object of the present invention is to provide an agent application tool having a comb portion and a handle, wherein the handle has a container-shaped handle body having an opening, A bag filled with an agent, provided in the handle body so as to share an opening, and detachably attached to the handle body so as to close a shared opening between the handle body and the bag. A first check valve provided on the lid, for allowing air to flow into the space between the handle body and the bag from outside,
A second check valve that is provided at a position corresponding to a common opening of the handle body and the bag in the lid, and that discharges the agent in the bag to the outside, the comb portion includes The lid is erected at a position corresponding to the second check valve,

By discharging from the comb to the surface of the comb teeth and releasing the pressing force applied to the handle, air flows into the space between the handle body and the bag via the first check valve. The problem is solved by an agent application tool characterized in that the agent application tool is configured to:

In this agent application tool, a neck portion is formed on the opening side of the handle main body, and the lid has a lower end in close contact with an outer peripheral portion below the neck portion of the handle main body. A first annular wall portion, a second annular wall portion which is inside the first annular wall portion and is screwed to a neck portion of the handle main body;
A top surface on which the first annular wall and the second annular wall are erected, wherein a first check valve is provided on the top surface and the first annular wall on the top surface. A through-hole is provided between the second annular wall portion and the second annular wall portion at a position that does not overlap with the second annular wall portion when the lid is screwed in the neck portion of the handle main body. The air that has passed through the first check valve can be configured to flow from the through hole into a space between the handle body and the bag.

[0008] Also, on the inner surface of the second annular wall portion on the top surface of the lid and on the surface on which the second annular wall portion is erected, a height higher than that of the second annular wall portion is provided. A third annular wall having a small size may be erected, and the opening-side end of the bag may be sandwiched between the third annular wall and the neck of the handle body. Furthermore, the third on the top surface of the lid

The fourth annular wall portion and the shaft of the comb portion inserted into the fourth annular wall portion may be configured to be sandwiched.

In the agent applicator having the above-described structure, after the handle body is pressed and the agent is discharged, when the pressing force is released, the air is integrated with the handle body by the volume of the discharged agent. It is taken into the space between the bags. Therefore, the handle body can be completely restored to its original shape, and there is no problem that the appearance gradually deteriorates with the ejection of the agent. The agent is filled in a bag, and the bag gradually shrinks as the agent is discharged. Therefore, there is no problem that a part of the agent does not come out while adhering to the inner wall of the handle body, and the agent can be almost completely used up. Further, in the agent applying tool of the present invention, the check valve is not provided on the handle body side where the agent is filled,
It is provided on the lid side that is reused together with the comb part. Therefore, when the agent application tool is reused, only the portion consisting of the handle body that can be manufactured at low cost and the bag filled with the agent is only disposable, and the handle portion filled with the agent (container portion) ) Can be replaced at low cost.

The air taken into the space C created between the neck 2 of the handle main body 1 and the first annular wall 5a of the lid 4 via the first check valve 8 is formed on the neck 2. Through the through hole 9, it is possible to flow into the space between the handle body 1 and the bag 3. In addition,
When the lid 4 is attached to the handle body 1, the through hole 9
Are provided so as not to overlap with the annular wall portion 5b.

A second check valve 10 for discharging the agent in the bag 3 to the outside is provided at a position corresponding to the common opening of the handle body 1 and the bag 3 in the cover 4, that is, at the center of the cover 4. Is provided. The second check valve 10 is jointly held by the fourth annular wall 5d and the lower end of the comb portion B as described above. In the present embodiment, the comb portion B is formed separately from the lid 4, but both may be integrated.

Next, the structure of the comb portion B will be described.
The comb portion B includes a shaft 11 and a plurality of comb teeth 12 erected on the shaft at predetermined intervals. The shaft 11 has a hollow shape in which the agent distribution chamber 13 is formed, and is erected at a position corresponding to the second check valve 10 on the lid 4. In other words, the shaft 11 is fitted and fixed to the lid 4 with a part of the second check valve 10 sandwiched between the lower end portion and the fourth annular wall portion 5d. Therefore, the agent distribution chamber 13 is in a state of being connected to the internal space of the handle body 1.

Inside the comb teeth 12, except for those located at the upper and lower ends, an agent guiding path 14 extending from the agent distributing chamber 13 is formed. Further, on both surfaces of the comb teeth 12, an agent discharge port 15 which continues from the agent guide path 14 is formed. In addition,
In the present embodiment, the two comb teeth 12 located at the upper and lower ends are integrally formed with the shaft 11. On the other hand, other comb teeth 1
As shown in FIG. 1, the connecting member 2 is a vertically connected body. The shaft 1 faces the agent distribution chamber 13.
By inserting the root portion 16 of the comb teeth 12 into the hole formed in 1, the linked comb body is fitted and fixed to the shaft 11.

Next, the function of the agent application tool having the above-described configuration will be described with reference to FIGS. First, as to the case of discharging the agent, as shown in FIG.

By pressing the handle body 1, the first
Air pressure acts on the check valve 8 from the inside, but the first check valve 8 does not open even when it receives a force from the inside to the outside.
Therefore, air does not escape from the first check valve 8, and the operation failure of the agent application tool due to this does not occur. After the agent is discharged, when the pressing force applied to the handle main body 1 is released, the handle main body 1 attempts to restore the original shape. At this time, since a negative pressure is generated in the handle body 1,
The first check valve 8 is opened, and air flows into the space between the handle body 1 and the bag 3 through the through hole 9 as shown in FIG. Since the volume of the discharged medicine is replaced by the inflowing air, the handle main body 1 is completely restored to the original state. This makes it possible to discharge the agent again. In addition, since the air is taken into the handle portion A, the same shape as when the agent is sufficiently filled is maintained regardless of the remaining amount of the agent. Therefore, the appearance does not deteriorate.

In the agent application tool of the present embodiment, the agent is filled in the bag 3, and the bag 3 gradually shrinks as the agent is discharged. Therefore, there is no problem that a part of the agent does not come out while adhering to the inner wall surface of the handle body 1,
The agent can be almost completely used up. Further, the agent application tool of the present embodiment does not have a problem that the cost is high when the agent is used up and reused. That is,
The first check valve 8 and the second check valve 10 are provided on the lid 4 side, and the lid 4 is reused together with the comb portion B. Therefore, only the portion consisting of the handle body 1 that can be manufactured at low cost by means such as blow molding and the bag 3 filled with the agent is disposable. Therefore, replacement of the handle portion (container portion) filled with the agent can be performed at low cost.
