Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an application shaft for applying an adhesive cosmetic liquid such as a mascara solution or a hair dye solution to eyelashes or hair.

[0002]

2. Description of the Related Art Conventionally, as this type of application shaft, a configuration in which a brush is implanted at the tip of a shaft body and a configuration in which fins are protruded are known. However, in these configurations, since the amount of liquid material such as mascara liquid attached to the brushes and fins is small, the tip of the shaft is repeatedly inserted into the container containing the liquid material at the time of application to replenish the liquid material. It had to be complicated.

[0003] As a solution to this complexity,
There has been proposed an improvement in which a shaft is provided with a hollow liquid reservoir communicating with the outside, and a liquid material is introduced and stored in the liquid reservoir to secure a required amount of liquid material.

[0004]

However, in this improvement, since the liquid material has an adhesive force, the liquid material in the liquid reservoir is not smoothly supplied to the brushes and the fins, and the liquid material is in the liquid reservoir. Despite the presence, there is a disadvantage that a liquid material cannot be applied to eyelashes or the like with a brush or fin. Further, in the case of a brush, there is also a disadvantage that the production is troublesome and the cost is high as compared with the fin.

[0005] It is an object of the present invention to solve these disadvantages and to provide a coating shaft capable of smoothly supplying a liquid material having an adhesive force introduced into and stored in a liquid reservoir to a fin.

[0006]

In order to achieve the above object, according to the present invention, the coating shaft of the liquid material having an adhesive force according to the first aspect of the present invention is provided with a hollow extending in the axial direction at a shaft core portion of a shaft body. The liquid reservoir is provided, and on the peripheral surface corresponding to the liquid reservoir, a number of notches for liquid circulation communicating with the liquid reservoir are provided at intervals in the axial direction, and a number of fins are provided at the interval. A plurality of through holes are formed on the peripheral surface opposite to each of the fins at intervals in the axial direction. The through holes also serve as a liquid inflow hole and an air hole communicating with the liquid reservoir.

According to another aspect of the present invention, there is provided an application shaft for a liquid material having an adhesive force according to the present invention, wherein the liquid reservoir portion extends to a tip end surface of the shaft body. It is characterized in that the notch for communicating with the outside and circulating the liquid occupies almost half of the peripheral surface.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a mascara shaft will be described below with reference to the accompanying drawings. Here, FIG. 1 is a side view showing the entire mascara shaft which is a coating shaft, FIG. 2 is an enlarged sectional view of a main part, and FIG.
2 is a sectional view taken along line AA, and FIG. 4 is a sectional view taken along line BB in FIG.

As shown in FIG. 1, a shaft body 1 of a mascara shaft 10 has a columnar shape, and a bottom 2a of a cylindrical holding part 2 having a bottom is fixed to a base end of the shaft body 1. As shown in FIG. 2 to FIG. 4, a hollow liquid reservoir 3 extending in the axial direction at the axis of the shaft 1.
The liquid reservoir 3 extends from a substantially central portion in the axial direction of the shaft body 1 to the opening 1a on the distal end surface and communicates with the outside.

As shown in FIGS. 1, 2 and 4, the peripheral surface of the shaft 1 corresponding to the liquid reservoir 3 occupies almost half of the peripheral surface and communicates with the liquid reservoir 3. Notch 4 for liquid distribution
Are provided at equal intervals in the axial direction, and a large number of semi-annular fins 5 are formed at intervals between the notches 4.

As shown in FIGS. 2 to 4, a through hole 6 serving as a liquid inflow hole and an air hole communicating with the liquid reservoir 3 is formed on the peripheral surface of the shaft body 1 on the side opposite to the fins 5. Four are provided at intervals in the axial direction.

Although not shown, the mascara shaft 10 is used in combination with the container containing the mascara liquid in the above-described embodiment provided with the grip portion 2 or has an appropriate configuration provided with the container. Use by incorporating into the tool. In the present embodiment, the coating operation is performed by holding the grip portion 2.

When the mascara shaft 10 is inserted into a container (not shown) containing mascara liquid, the mascara liquid flows into the liquid reservoir 3 through the opening 1a, each notch 4 and each through hole 6, and The mascara liquid is also present in each of the notches 4 which are spaces between the fins 5. Here, when the mascara shaft 10 is pulled out of the container, the liquid reservoir 3
And mascara liquid remains in the four notches, and each fin 5
Becomes a state where the mascara liquid adheres to the surface.

Therefore, the mascara liquid adhering to each fin 5 can be applied to the eyelashes by the same application operation as in the prior art. And since each through-hole 6 acts as an air hole, although the mascara liquid has adhesiveness, the mascara liquid corresponding to the usage amount is filled in each notch 4 between each fin 5 by the liquid reservoir 3. Can be replenished smoothly and reliably.

In this manner, as long as the mascara liquid is present in the liquid reservoir 3, the mascara shaft 10 is smoothly supplied to each fin 5 without inserting the mascara shaft 10 into the container containing the mascara liquid. The application operation to the eyelashes can be continued. Normally, the application operation can be completed without refilling the mascara liquid in the container on the way.

The present invention is not limited to the above-described embodiment. For example, the shaft body 1 provided with the through hole 6 does not necessarily need to have the opening 1a at the tip end surface, and the liquid reservoir 3
May be configured to communicate with the outside through each notch 4. Further, each notch 4 is not limited to one extending over a half circumference of the peripheral surface of the shaft body 1 and can be set as appropriate.

[0017]

As is clear from the above description,
According to the application axis of the liquid material having the adhesive force, which is the invention of claim 1 of the present application, the liquid material according to the usage amount is supplied to each fin sequentially and smoothly from the liquid reservoir, so that the liquid As long as there is a liquid in the reservoir, the application shaft can be continuously applied to the application target such as eyelashes without inserting the application shaft into the container containing the liquid and replenishing the liquid. There is an effect that a coating operation can be performed.

Further, according to the application axis of the liquid material having adhesive force according to the second aspect of the present invention, in addition to the above-described effects,
There is an effect that the application operation to the application object can be performed more efficiently and easily.
