Japanese Unexamined Patent Publication No. 2001-204543

By the way, when applying a chemical solution or the like using a liquid coating tool as described above, since it is necessary to limit the coating area, a liquid coating member having a small amount of hair is often used. With such a liquid coating member, the amount of liquid held in the brush could not be increased, and a large amount of liquid could not be applied to the coating target at one time. It should be noted that such a problem is a problem that can occur not only in the brush but also in the entire liquid coating member having a spatula or the like for coating the liquid.

The present invention has been made to solve this problem, and to provide a liquid coating member capable of holding a larger amount of liquid and applying the liquid to an object to be coated, and a liquid coating tool provided with the liquid coating member. With the goal.

The liquid coating tool according to the present invention includes a shaft portion having a first end portion and a second end portion, a liquid holding portion attached to the first end portion of the shaft portion and having a through hole formed therein, and the liquid holding portion. The shaft portion is attached to the side opposite to the first end portion of the shaft portion, and includes a coating portion for applying the liquid to the coating target.

This liquid coating member is used as follows. That is, the liquid is immersed in the coating portion, the liquid is held in the coating portion, and then this liquid is applied to the coating target. At this time, even if the amount of liquid that can be held in the coating portion is small, the liquid can be retained in the through holes by immersing the liquid in the liquid holding portion. Then, when the coating portion is turned downward and pressed against the coating target, the liquid held in the through hole flows to the coating portion, and more liquid can be coated on the coating target. Alternatively, if the through hole is brought close to the coating target by strongly pressing the coating portion against the coating target, the liquid held in the through hole can be directly applied to the coating target. Therefore, according to the present invention, more liquid can be retained and applied to the object to be applied.

In the liquid coating member, at least a part of the thickness of the first end portion of the shaft portion is formed to be larger than the thickness of the liquid holding portion, so that the first end portion of the shaft portion and the liquid holding portion are formed. A step can be formed at the boundary with.

According to this configuration, by forming a step at the boundary between the first end portion of the shaft portion and the liquid holding portion, the liquid can be held in the step portion in addition to the through hole in the liquid holding portion. .. That is, more liquid can be held in the liquid holding portion. Therefore, more liquid can be applied to the application target.

In each of the liquid coating members, the coating portion has a mounting surface of the shaft portion facing the axial direction, and a plurality of hairs mounted on the mounting surface and extending in the axial direction, and the mounting portion has the mounting surface. The surface is composed of a surface defined by a first direction and a second direction orthogonal to the first direction, and the plurality of hairs are arranged so as to line up in the first direction, and at least one set. It can be assumed that the roots of the hairs adjacent to the first direction are arranged so as to be displaced in the second direction.

According to this configuration, since the coating portion has a plurality of hairs and the roots of the adjacent hairs are arranged so as to be displaced in the second direction, the liquid can be held in the step caused by the hairs. Therefore, more liquid can be held in the liquid holding portion, and these can be applied to the application target.

In the liquid coating member, the plurality of hairs can be formed in a plate shape extending in the second direction.

According to this configuration, first, the adjacent hairs are arranged so as to be displaced in the second direction. Therefore, when the liquid is applied to the application target, the hairs that are displaced to the opposite side to the application target in the second direction ( The contact of the first hair (hereinafter referred to as the first hair) with the application target is smaller than that of the hair displaced toward the application target side (hereinafter referred to as the second hair). Therefore, when the liquid is applied, the movement of the first hair is smaller than that of the second hair. As a result, even if the second hair moves in the first direction, this movement is regulated by the first hair. As a result, it is possible to prevent the plurality of hairs from spreading in the first direction. In particular, since both the first hair and the second hair are formed in a plate shape, the effect of regulating the second hair by the first hair is large. Therefore, since the liquid is applied in a state where the plurality of hairs do not spread and are gathered together, the liquid easily separates from the hairs. As a result, the liquid can be applied efficiently.

In each of the liquid coating members, the tips of the plurality of hairs can be arranged at substantially the same position in the second direction.

According to this configuration, since the tips of the plurality of hairs are arranged at substantially the same position in the second direction, the plurality of hairs are lined up in the first direction with the tips aligned. Therefore, the liquid held by the hair tends to separate from the hair when the hair is pressed against the application target. Therefore, more liquid can be reliably applied to the object to be applied. It should be noted that the "substantially the same position" means not only the exact same position but also a slight deviation from the exact same position to the extent that the above effect can be obtained.

The liquid coating tool according to the present invention has an opening, a container in which a liquid is stored, a cap that detachably closes the opening, and a second end portion of the shaft portion attached to the cap, and the cap is attached. It comprises any of the above-mentioned liquid coating members that extend into the internal space of the container when attached to the opening.

In the liquid coating tool, the viscosity of the liquid can be 500 to 500,000 mPa · s at 20 ° C.

As described above, when the liquid has viscosity, it becomes easy to hold the liquid in the liquid holding portion, the coating portion, and the like, and the coating amount can be increased.

According to the present invention, more liquid can be retained and applied to the object to be applied.

The lid member 412 is formed in a disk shape and has a size to be fitted into the small diameter portion 32 of the inner plug 3 described above. Specifically, when the lid member 412 is fitted into the small diameter portion 32 of the inner plug 3, the gap between the outer edge of the lid member 412 and the inner wall surface of the small diameter portion 32 is preferably 0.1 mm or more. Specifically, it is preferably about 0.1 to 1 mm.

As shown in FIG. 4, the shaft body 413 is formed in a plate shape having a width substantially the same as the diameter of the lid member 412, and extends downward. Here, as shown in FIG. 4, a pair of wide left and right surfaces of the shaft body 413 are referred to as a first surface 4131 and a second surface 4132, and have a width for connecting the first surface 4131 and the second surface 4132. A pair of narrow (small thickness) surfaces will be referred to as side surfaces 4133. A liquid holding portion 42 having a rectangular shape in front view is connected to the lower end portion (first end portion) of the shaft body 413.

As shown in FIGS. 5 and 6, the liquid holding portion 42 has a first surface 421 and a second surface 422 that are connected to the first surface 4131 and the second surface 4132 of the shaft body 413, and further has a side surface of the shaft body 413.

<4. How to use and features of liquid coating tool>
Next, a method of using the liquid coating tool configured as described above will be described with reference to FIGS. 9 to 14. However, in FIGS. 11 to 14, for convenience of explanation, the cap 2 is omitted and only a part of the liquid coating member 4 is shown. As shown in FIG. 2, when the cap 2 is attached to the container 1, the container 1 contains an amount of a chemical solution that reaches the vicinity of the upper end of the shaft portion 41 of the liquid coating member 4. At this time, since the lid member 412 closes the lower end opening of the small diameter portion 32 of the inner plug 3, for example, even if the container 1 is tilted, it is possible to prevent the chemical solution from flowing to the cap 2 side. However, since a slight gap is formed between the lid member 412 and the small diameter portion 32 of the inner plug 3, it is possible to prevent the shaft portion 41 from becoming difficult to pull out. Even if such a gap is formed, since the chemical solution has viscosity, it is possible to prevent the chemical solution from leaking from the gap.

Then, after rotating the cap 2 from the state of FIG. 2 to release the screwed state with the upper end portion of the container 1, when the cap 2 is pulled up as shown in FIG. 9, the liquid coating member 4 is released together with the cap 2. Will also be raised. At this time, since the chemical solution is viscous, the chemical solution is applied not only to the outer peripheral surface of each hair 432 in the brush portion 43, but also to the through hole 424 of the liquid holding portion 42 and the step portion 45 between the liquid holding portion 42 and the shaft portion 41. Be retained. Further, as shown in FIG. 10, since the recess 433 as described above is formed by the step between the roots of the adjacent hairs 4321 and 4322, the chemical solution is also held in these recesses 433. Therefore, a large amount of chemical solution can be attached to the brush portion 43.

Then, as shown in FIG. 11, when the brush portion 43 to which the chemical solution is attached is applied to the surface to be applied, the chemical solution held in the step 45 or the through hole 424 flows to the brush portion 43 side, so that the brush portion 43 In addition to the chemical solution adhering to the above, the chemical solution flowing from the step 45 or the through hole 424 can also be applied to the surface to be applied. Further, as shown in FIG. 8, since the bristles 4323 are aligned, the chemical solution can be easily separated from the brush portion 43, and the chemical solution can be effectively applied to the surface to be applied.

Further, as shown in FIG. 12, when the liquid coating member 4 is tilted and the through holes 424 and the step 45 are brought close to the coating target surface, the chemical solution held therein can be directly applied to the coating target surface.

Further, the following effects can be obtained. This will be described with reference to FIG. FIG. 13 is a cross-sectional view of the brush portion 43, which mainly shows a state in which the tip end side of the second bristles 4322 is in contact with the surface to be coated. At this time, although the tip end side of a part of the first hair 4321 is also in contact with the surface to be coated, since these are arranged so as to be offset from the first surface 421 side of the liquid holding portion 42, the first hair 4321 On the root side, contact with the surface to be coated is more restricted than that of the second hair 4322. Therefore, when the chemical solution is applied, the movement of the first hair 4321 is smaller than that of the second hair 4322. As a result, even if the second hair 4322 moves in the longitudinal direction, this movement is regulated by the first hair 4321. In particular, since both the first hair 4321 and the second hair 4322 are formed in a plate shape, the effect of regulating the second hair 4322 by the first hair 4321 is great. Therefore, as shown in FIG. 14B, the bristles constituting the brush portion are difficult to spread in the longitudinal direction, and as shown in FIG. 14A, a plurality of bristles 432 come into contact with the surface to be applied in a state of being gathered, and the chemical solution is used. Can be applied. Therefore, the chemical solution can be easily separated from the brush portion 43, and the chemical solution can be effectively applied to the surface to be applied.

As described above, according to the liquid coating tool according to the present embodiment, a large amount of the chemical solution can be adhered to the brush portion 43, and the adhered chemical solution can be efficiently applied to the surface to be coated. Therefore, it is possible to apply a large amount of the chemical solution to the surface to be coated, or to apply the chemical solution to the surface to be coated having a large area.
