The cross-sectional shape of the one shown in FIG. 1 is C-shaped and has one entrance / exit portion. Then, when a twisting brush is made using these bristle materials, a certain gap b (see FIG. 5) still exists between the bristle materials.

[0004]

In the conventional mascara brush, an elongated application object such as eyelashes is the gap b.
There is a problem that it is difficult to smoothly apply the liquid agent because the liquid agent does not come into contact with the hair material and does not adhere thereto.

It is an object of the present invention to solve the above problems, and an object of the present invention is to provide a twisting brush for applying a liquid agent that solves the problems.

[0006]

In order to achieve the above object, the torsion brush for applying a liquid agent according to the present invention described in claim 1 twists a plurality of core materials sandwiching the central portion of many bristle materials. Thus, the twisting brush is formed by spirally projecting the bristle material around the core material, and the bristle material has a lateral cross-sectional shape in which a plurality of protrusions are formed on both sides of the bristle portion so that the groove portions are connected to each other. It is characterized by a bellows shape bent in a zigzag manner.

Further, in the twist brush for applying a liquid agent according to a second aspect of the present invention, a plurality of core materials sandwiching the central portion of a large number of bristle materials are twisted, so that the core material is centered around the core material. A twisting brush formed by spirally projecting a bristle material, wherein the bristle material has a cross-sectional shape in a zigzag-folded bellows shape so that a plurality of protrusions are connected on both sides with a groove between them. It is characterized in that the tip end side of the portion of each protrusion corresponding to each groove is bulged so as to form a constriction on the inlet side of each groove.

Furthermore, the twisting brush for applying a liquid agent according to the invention described in claim 3 is characterized in that the groove portion according to claim 1 or 2 is 6 to 10.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION A first embodiment in which the present invention is applied to a mascara brush will be described below with reference to FIGS. 1 to 3 of the accompanying drawings. Here, FIG. 1 is a partial vertical cross-sectional view of the mascara container showing a state in which the mascara brush is being pulled out, FIG. 2 is a perspective view of the crossed bristle material, and FIG. 3 is a partially enlarged view of the application part.

As shown in FIGS. 1 and 3, the mascara brush 1 includes a plurality of bristle materials 2 by twisting a plurality of core materials 3 sandwiching the central portion of the bristle material 2 on one end side. 3 to form a coating portion 1a spirally protruding around the center,
The other end side of the core material 3 is inserted into a pipe body 6 having a knob 5 which also functions as a cap of the container 4 on one end side, and the coating portion 1a is formed.
Is projected from the other end of the pipe body 6.

As shown in FIG. 1, the mascara brush 1 is
When not in use, it is stored in the container 4 in a state of being immersed in the mascara liquid 7, and when used, the knob 5 which also functions as a cap is turned to unscrew, and pulled out from the mouth of the container 4. While holding the knob 5, the makeup is applied to the eyelashes by the application portion 1a to which the mascara liquid 7 is attached. Further, inside the mouth of the container 4, there is provided a handle 4a for handling the bristle 2 and scraping off the excess mascara liquid 7.

As shown in FIG. 2, the cross-sectional shape of the bristle material 2 is such that four protrusions 8 on each side, three protrusions 8 on each side, and a total of 6 groove portions 9.
Are formed in a bellows shape that is bent in a zigzag manner so as to be connected in series. The bristle material 2 is made of a thermoplastic synthetic resin such as polyester or nylon, and has a substantially quadrangular cross section, and its size is 0.05 mm to 0.35 mm on a side.
The degree is suitable. The number of the groove portions 9 is 6 to 1
0 is preferable. That is, if the number of the groove portions 9 is 5 or less, the amount of the mascara liquid 7 held is insufficient, and if the number of the groove portions 9 is 11 or more, the amount of the mascara liquid 7 held is too large.

Further, as shown in FIG. 2, in the cross-sectional shape of the bristle material 2, it corresponds to each groove portion 9 of each of the protrusions 8 so that a constricted portion 10 is formed at the entrance / exit side of each groove portion 9. The tip end side of the portion has a bulged shape, and the projection 8 has a curved outer periphery. By thus forming the constricted portion 10 on the entrance / exit side, the inner side of the groove 9 is wider than the constricted portion 10 on the entrance / exit side.

As shown in FIG. 3, when the twisting brush is produced, the bristle material 2 is laterally moved by twisting a plurality of core materials 3 sandwiching the central portion of the many bristle materials 2 on one end side as described above. It is crushed by the force from and each bends in indefinite direction,
Since it spreads evenly, the gap does not exist.

Then, in the hair material 2 of the application portion 1a pulled out from the container 4, the mascara liquid 7 is placed in the groove portion 9 thereof.
Since the twisting brush 1 created by using this bristle material 2 has a constricted portion 10 in the groove portion 9 of the bristle material 2 and the back side is wider than the entrance / exit side, the action of holding the mascara liquid 7 is large. At the same time, since the four protrusions 8 are continuously provided on both sides with the three groove portions 9 in between, the mascara liquid 7
In the application operation, the mascara liquid 7 held in the groove 9 is reliably pulled out when the tips of the protrusions 8 of the bristle material 2 come into contact with the eyelashes.

Next, a second embodiment of the present invention will be described with reference to FIG. 4 of the accompanying drawings. Here, FIG. 4 is a perspective view of the traversed bristle material.

The cross-sectional shape of the bristle material 20 of the second embodiment is that the bristle material of the first embodiment has a configuration in which three protrusions are provided on both sides and two groove portions are continuously provided between them. 2, the shapes of the protrusion, the groove, and the constriction are the same as those of the bristle material 1, so detailed description thereof will be omitted, and the protrusion, the groove, and the constriction shown in FIG. The reference numerals 8, 9 and 10 used in the first embodiment are attached.

A mascara brush (not shown) using the bristle material 20 has a bristle material 2 crushed by a lateral force, as in the first embodiment, and each of them is in an undefined direction. Since it bends to and spreads out evenly, the gap does not exist.

Further, the mascara brush (not shown) using the bristle material 20 has one protrusion 8 and one groove portion 9 less than the bristle material 2 of the first embodiment, and therefore is retained in the groove portion 9. Although the amount of the mascara liquid 7 is a little small, the action of holding the mascara liquid 7 is sufficiently large, and the mascara liquid is reliably pulled out even in the application operation of the mascara liquid, so that the application work is easy.

The present invention is not limited to the above-described embodiments. For example, the total number of the groove portions 9 is preferably 6 to 10, but the total number is 2, 3, 5, or 5. Alternatively, the total number may be 11 or more. It can also be used for applying liquid agents other than mascara.

[0021]

As described above, according to the present invention as set forth in claim 1, the cross-sectional shape of the bristle material is zigzag so that a plurality of projections are formed on both sides of the bristle in a continuous manner with a groove between them. Since it is formed into a bellows shape that is bent into a shape, the bristle material is crushed by the force from the side at the time of creation, and each bends in indefinite directions and spreads evenly in each direction, so there is no gap, so applying the liquid agent Has the effect of being easy to peel.

According to the present invention described in claim 2, in addition to the effect of the invention described in claim 1, in the cross-sectional shape of the bristle material, a constricted portion is formed in the groove portion, and the entrance / exit side of the groove portion is deep. Since the liquid agent is narrower than the side, it has a large effect of holding the liquid agent, and in the application operation of the liquid agent, the liquid agent is reliably pulled out from the plurality of grooves, so that the application work is easy.
