Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mascara makeup tool, and more particularly, by forming an opening of a squeezing member for squeezing excess mascara agent from a brush portion into a specific shape.
The present invention relates to a mascara makeup tool in which an appropriate amount of mascara agent remains in the central portion and the outer peripheral portion of the brush portion.

[0002]

2. Description of the Related Art A mascara makeup tool 1 is schematically shown in FIG.
As shown in (a) and (b), it comprises a mascara agent container 3 for accommodating the mascara agent 2, a brush part 4, and a cap member 5 which also serves as a handle of the brush part 4 and a cap of the mascara agent container 3. The brush portion 4 is a core material 6 formed by twisting wires together.
And the fibers 7 sandwiched between the wire rods of the core material 6 and arranged around the core material 6.

On the other hand, inside the mascara agent container 3, the brush portion 4 is inserted into the mascara agent container 3 to remove the mascara agent 2
When the brush portion 4 is taken out from the mascara agent container 3 after the adhering, the squeezing member 8 is attached to squeeze out the excess mascara agent 2. Ironing member 8
As shown in FIG. 8C, is a plate-shaped member made of an elastic material such as rubber, and has a circular opening 9.

[0004]

However, according to the conventional ironing member 8 having the circular opening 9, the brush portion 4 taken out from the mascara agent container 3 has the mascara agent only in the central portion of the brush portion 4. It remains, and it hardly remains on the outer peripheral portion.

On the other hand, the amount of eyelashes entering the central portion of the brush portion 4 varies depending on the length and amount of the eyelashes and how the brush portion 4 is used. In either case, the mascara agent is applied only to the central portion of the brush portion 4. When it is present, the mascara cannot be applied to the eyelashes unless the eyelashes enter the center of the brush, and conversely, a large amount of mascara adheres to the eyelashes if the eyelashes enter too much in the center of the brush. It becomes a mess, and eventually there arises a problem that a uniform finish and curl-up effect cannot be obtained for each lash.

Particularly, as the fibers 7, long fibers and short fibers are periodically located in the circumferential direction of the core material 6, and the shape of the cross section of the envelope surface 10 of the fibers 7 (the surface perpendicular to the longitudinal direction of the brush portion 4). When the shape is polygonal or the like, a large amount of mascara agent remains in the short fiber portion as compared with the long fiber portion. Therefore, the eyelashes are more likely to be fooled.

Further, in order to improve the catch-up feeling and the long rush effect, the mascara agent 2 has a viscosity of 50.
When using a high-viscosity product having a viscosity of 000 mPa · s (temperature 23 ° C, B-type viscometer (No. 4 rotor, 6 rpm)) or more, it is difficult for the eyelashes to enter the central portion side of the brush portion 4, so the mascara agent When 2 exists only in the center of the brush portion 4, there is a problem that the amount of the mascara agent applied to the eyelashes decreases.

In response to such a problem, the present invention relates to a mascara makeup tool, in which an appropriate amount of mascara agent is left in the central portion and the outer peripheral portion of the brush portion taken out from the mascara agent container, so that the eyelashes are not fooled. Applying beautifully a mascara agent to each one to obtain a uniform finish and curl-up effect. Especially, even a high-viscosity mascara agent can be easily applied to provide excellent catch-up feeling and long lash effect. It is intended to be obtained.

[0009]

Means for Solving the Problems The present inventor has made the opening portion of the ironing member into a star shape having a specific size so that the central portion and the outer peripheral portion of the brush portion taken out from the mascara agent container can be formed. Also found that an appropriate amount of mascara could be left behind.

That is, the present invention relates to a mascara makeup tool comprising a core material made of twisted wire rods, a brush part made of fibers arranged around the core material, and a mascara agent container provided with an ironing member. The ironing member has a star-shaped opening, and the diameter of the circumscribing circle of the opening is the projection line or the projection line of the envelope surface of the fiber on the ironing member in the state where the brush portion is completely inserted into the mascara container. Provided is a mascara makeup device having a diameter smaller than the circumscribed circle of a line and having an area occupied by the opening of 20 to 70% in a region between the inscribed circle of the opening and the circumscribed circle of the opening.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below with reference to the drawings. In each figure, the same reference numerals represent the same or equivalent constituent elements.

FIG. 1 is a side view (a), a sectional view (b) and a plan view (c) of an ironing member of a mascara makeup tool 1A according to an embodiment of the present invention.

This mascara makeup tool 1A is known in that it is composed of a mascara agent container 3 for containing the mascara agent 2, a brush portion 4, and a cap member 5 which also serves as a handle of the brush portion 4 and a cap of the mascara agent container 3. Mascara makeup tool 1
Is the same as. The brush portion 4 is composed of a core material 6 in which wire materials are twisted together, and fibers 7 sandwiched between the wire materials of the core material 6 and arranged around the core material 6, and the envelope surface 10 of the fiber 7 has a cylindrical shape. There is. Further, inside the mascara agent container 3, when the brush portion 4 is inserted into the mascara agent container 3 and then taken out from the mascara agent container 3, a squeezing member is used to squeeze out the excess mascara agent 2 adhering to the brush portion 4. 20A is provided.

In this mascara makeup tool 1A, the opening 21 of the ironing member 20A has a star shape having five apices (that is, when the brush portion 4 is completely inserted into the mascara container 3). It is characterized in that it is formed in a region between the projection line 11 of the enveloping surface 10 onto the ironing member 20A and the surface of the core material 6 and a line formed by periodically reciprocating five times between the center side and the outside. Has become.

Here, the diameter of the circumscribing circle 23 of the opening 21 is
A projection line 11 of the envelope surface 10 of the fiber 7 onto the ironing member 20A
Is smaller than the diameter of. Further, in the area between the inscribed circle 22 and the circumscribed circle 23 of the opening 21, the area occupied by the opening 21 is 20 to 70%, preferably 30%.
50%.

By thus forming the opening 21 in a star shape of a specific size, the portion 2 of the star shape having a small opening diameter is formed.
1a, the fibers 7 of the brush part 3 can be sufficiently squeezed, and conversely, the degree of squeezing of the fibers 7 of the brush part 3 can be weakened in the portion 21b having a large star-shaped opening diameter. After being inserted into the mascara agent container 3 and then taken out, an appropriate amount of the mascara agent is left in the central portion and the outer peripheral portion of the brush portion 4, and the mascara agent is attached even to the tips of the fibers 7 of the brush portion 4. You can Therefore, even a general person can beautifully apply the mascara agent to each of the eyelashes without fooling them and improve the curl-up effect.

Further, in order to reduce the force required to pass the base portion 13 of the core member 6 through the opening portion 21 while maintaining the effect of making the opening portion 21 into a star shape, the inner portion of the opening portion 21 is inscribed. The ratio of the diameter of the circle 22 to the diameter of the circumscribing circle 23 of the opening 21 is preferably 0.2 to 0.9, and particularly,
It is preferably 0.4 to 0.8. More specifically, the diameter of the inscribed circle 22 of the opening 21 or the circumscribed circle 23
Depending on the individual size of the diameter of the
When the diameter of the cross section of the envelope 10 is 5.5 to 6.0 mm, the diameter of the inscribed circle 22 of the opening 21 is 1.5 to
The diameter of the circumscribing circle 23 of the opening 21 is set to 4.0 mm.
0 to 5.0 mm. As the material for forming the ironing member 20A, a thermoplastic elastomer such as nitrile rubber, polystyrene-based elastomer, or polyolefin-based elastomer can be used.

The diameter of the base portion 13 of the core material 6 is such that the opening portion 21 is completely closed when the brush portion 4 is inserted into the mascara agent container 3 and the mascara agent 2 leaks from the inside of the mascara agent container 3. So that it does not come out, or the brush section 4
The diameter of the circumscribing circle 23 of the opening 21 is preferably larger so that the mascara agent adhering to the base portion 13 can be squeezed when the is removed from the mascara agent container 3. Alternatively, the diameter of the core material 6 itself may be increased on the side of the cap member 5 so that the opening 21 is completely closed by the core material 6 when the brush portion 4 is inserted into the mascara agent container 3.

The mascara agent 2 applied with the mascara makeup tool 1A is not particularly limited. 50,000m effective for improving the catch-up feeling and long rush effect
Pa · s (Temperature 23 ° C, B-type viscometer (No. 4 rotor, 6
With respect to the high-viscosity mascara agent having a rotational speed of (rpm)) or higher, the eyelashes are unlikely to enter the central portion of the brush portion 4. Therefore, according to the conventional mascara makeup device, the mascara agent cannot be sufficiently applied to the eyelashes. According to the mascara makeup tool of No. 1, even such a high-viscosity mascara agent can be beautifully applied to the eyelashes, so that the use of the mascara makeup tool 1A of the present invention has great significance.

The mascara makeup tool of the present invention can take various modes other than the mode shown in FIG. For example,
The star shape of the opening 21 of the ironing member 20A is not limited to the star shape having five apex portions as shown in FIG. However, if the number of star-shaped tops is too small, after passing through the ironing member 20A, the mascara agent remaining on the brush portion 4 becomes too uneven in the circumferential direction of the brush portion, and conversely if too many, the ironing member 20A Workability is reduced. For this reason, the star-shaped opening 2
The number of tops of 1 is preferably 3 from the ironing member 20B shown in FIG. 2 to 8 as the ironing member 20C shown in FIG. 3, and is particularly preferably 5 to 6. . In addition, the shape of the opening 21 may be an indeterminate shape in which the distances from the center of the opening 21 to the respective tops are not uniform, as in the ironing member 20D shown in FIG. 4, and the ironing member shown in FIG. It may be a star shape like a gear like 20E. Even when the shape of the opening 21 is an irregular shape or a star shape like a gear, the number of tops is preferably 3 to 8, and particularly preferably 5 to 6.

Further, in the brush portion 4, the length of the fibers 7 is not limited to be the same in the circumferential direction of the core material 6, but may be periodically different in the circumferential direction of the core material 6. In this case, it is preferable that the star shape of the opening of the ironing member corresponds to the shape of the projection line of the envelope surface of the fiber onto the core material. For example, as shown in FIG. 6, the brush portion 4 is composed of long fibers and short fibers periodically arranged around the core material 6, and the cross-sectional shape of the envelope surface 10 of these fibers 7 is substantially hexagonal. In such a case, the shape of the opening 21 of the ironing member 20F as shown in FIG. 7 is preferably a star with six peaks. In this case, the diameter of the circumscribing circle 23 of the opening 21 is made smaller than the diameter of the circumscribing circle 12 of the projection line 11 of the envelope surface 10 of the fiber 7 onto the ironing member 20F. In addition, it is preferable to provide a positioning means so that the top of the envelope surface 10 and the top of the opening 21 can be easily positioned when the brush part 4 is inserted into the mascara agent container 3. For example, a cap member. 5 and the mascara container 3 are formed with fitting parts and the like.

EFFECTS OF THE INVENTION According to the mascara makeup tool of the present invention, an appropriate amount of mascara can be left in the central portion and the outer peripheral portion of the brush part taken out from the mascara container. Therefore, it is possible to apply the mascara agent beautifully to each eyelash without fooling it, and to obtain a curl-up effect. In particular, according to the mascara makeup tool of the present invention, even when applying a high-viscosity mascara agent which makes it difficult for the eyelashes to enter the central portion of the brush portion, the mascara agent can be easily applied to the eyelashes, which is an excellent catch-up. A feeling and a long rush effect can be obtained.
