The operation of the problem solving means 5 is as follows. When the base part is made of plastic, the second joint opening part between the handle part and the base part can be manufactured even when the shape of the joint opening part between the base part and the brush part is completely different. Thereby, even when the shape of the handle part considering the ease of holding and the shape of the brush part considering the ease of use are completely different, it is possible to manufacture a makeup and facial brush.

The action of the problem solving means 6 is as follows. By having the base portion inclined, it is possible to manufacture brushes having different hair tips within one brush.

The action of the problem solving means 7 is as follows. By manufacturing with a plastic material and flocking to this, the shape of the tip of the hair is made sharper, so that the brush tip has a sharper shape on the side, corner, or curved part with a small curvature. Will be able to keep. By keeping the edges with sharp edges and corners or curved parts with a small curvature, the edges and corners of sharply formed edges and the curved parts with a small curvature can be used to create details on the face. It can be used to maintain a certain nose and eyebrows. Furthermore, the entire hair tip surface can be used for a wide area of the face such as a cheek or forehead.

As described above, the cosmetic and face-washing brush of the present invention is a plane that intersects the polygonal shape of the joint opening portion of the base portion and the brush portion or the curved shape having the uneven portion or the shape combined with the curve or straight line perpendicularly to the axis. The shape projected on the face and the shape projected on the plane perpendicular to the axis of the brush tip are the same as or similar to each other, from wide areas of the face such as cheeks and foreheads to details around the nose Can be covered with one brush.

Cross-sectional view of the base that supports the brush

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the present invention includes a brush part 1, a base part 2 that supports the brush part 1, and a handle part 3 that supports the base part 2. The hair of the brush portion 1 may be artificial hair, natural hair, or a mixture of artificial hair and natural hair. It is necessary to select hair quality in consideration of the purpose of use and durability. The joint opening 5 refers to an opening at an end of the base part 2 that holds the hair of the brush part 1 on the brush part 1 side, and after the flocking, the opening is filled with the flocked hair. The axial center line 15 is a joint opening 5 between the center point (not shown) of the plane having the second joint opening 4 with the handle 3 of the base 2 as a plane and the brush 1 of the base 2. Is a straight line connecting the center point (not shown) of the plane with a straight line and extending toward the brush part 1 and the handle part 3.

As shown in FIG. 1, in the present invention, a curved shape having a polygonal shape or an uneven portion of the joint opening 5 of the base portion 2 or a shape obtained by combining curved or straight lines is projected onto a plane perpendicular to the axial center line. And the shape which projected the hair end surface 12 of the brush part 1 on the plane perpendicular | vertical to the axial center line 15 becomes the same or similar shape. FIG. 1 shows a case where the polygonal shape is a quadrangle. In the case of FIG. 1, a quadrilateral 51 (not shown) having a planar area S1 formed by the joint opening 5 of the base portion 2 intersects the axial center line 15 perpendicularly. Projections projected onto intersecting vertical planes (polygons with an area S2 (not shown)) are squares 52 having the same area (S1 = S2) and the same shape. Further, assuming that the area of the plane of the quadrangle 53 of the hair tip surface 12 formed by the hair tip of the brush portion 1 is S3, a projection figure 13 (area) in which the hair tip surface 12 is projected onto a vertical plane intersecting the axis 15 The polygon of S4) has a one-to-one similarity ratio to the projection projected onto the plane perpendicular to the axis 15 of the quadrangular plane 51 formed by the joint opening 5 of the base part 2, that is, the same area (S1). = S2 = S4), it is a quadrangle having the same shape. Depending on the purpose of use, the polygonal shape of the connection opening 5 of the base part 2 and the area of the projection 13 in which the hair end surface 12 of the brush part 1 is projected onto a plane perpendicular to the axis line can be changed. That is, for example, the projection 13 in which the hair end surface 12 of the brush portion 1 is projected onto a vertical plane intersecting the axis is identical to the polygonal shape of the connection opening 5 projected onto the plane perpendicular to the axis. Alternatively, if the similar shape is maintained, the area of the hair end surface can be increased or decreased by changing the similarity ratio. In addition, although it is the same or similar meaning, it is not a mathematically exact meaning and includes the meaning of substantially the same or substantially similar.

As shown in FIG. 2, the brush portion 1 has an inclination 14 when the brush portion 1 is viewed from the side. There may be no inclination according to the purpose of use. That is, the inclination 14 may be perpendicular to the axis 15. When one side 7 in the axial center line 15 direction of the brush part 1 is longer than one side 6 in the axial center line 15 direction of the brush part 1, the side 9 of the brush part 1 faces as shown in FIG. 3. Longer than side 8 to be Since the brush part is formed according to the purpose, the side 7 of the brush part 1 shown in FIG. 2 and the side 9 of the brush part 1 shown in FIG. 3 do not have to have the same length. Further, the side 6 of the brush part 1 shown in FIG. 2 and the side 8 of the brush part 1 shown in FIG. 3 do not have to have the same length.

As shown in FIG. 6, the size of the brush portion 1 is desirably h 5 mm to 60 mm and w 5 mm to 60 mm. If the size of the brush part 1 is too small, it may be inconvenient when used on a wide area of the face such as a cheek or forehead. Even if the size of the brush part 1 is too large, it may be inconvenient when used for details such as the nose around the face.

As shown in FIG. 2, when the side 7 of the brush part 1 which opposes the side 6 of the brush part 1 is longer, the hair length a1 of the side 6 of the brush part 1 is preferably 2 mm or more and 60 mm or less. As shown in FIG. 3, when the side 9 of the brush part 1 which opposes the side 8 of the brush part 1 is long, the hair length b1 of the side 8 of the brush part 1 is desirably 2 mm or more and 60 mm or less.

As shown in FIG. 2, when the side 6 of the brush part 1 opposite to the brush part 1 is shorter than the side 7 of the brush part 1, the bristle length a3 of the side 7 of the brush part 1 is desirably 2 mm or more and 60 mm or less. As shown in FIG. 3, when the side 8 of the brush part 1 which opposes the side 9 of the brush part 1 is short, the hair length b3 of the side 9 of the brush part 1 is desirably 2 mm or more and 60 mm or less.

When using it for face washing, when it is desired to place emphasis on foaming, the hair lengths a1 and a3 of the side 7 of the brush unit 1 opposite to the side 6 of the brush unit 1 shown in FIG. 2, and the brush part 1 shown in FIG. It is desirable that the lengths b1 and b3 of the hairs on the sides 8 and 9 are made longer from about 15 mm to about 35 mm. When emphasis is placed on solid washing comfort rather than foaming, the hair lengths a1 and a3 of the side 7 of the brush unit 1 facing the side 6 of the brush unit 1 shown in FIG. It is desirable that the bristles b1 and b3 of the side 9 of the brush portion 1 facing the side 8 have a length of about 5 mm to 15 mm. However, the length of the hair tip can be changed according to the purpose of use.

When the brush part 1 has an inclination, as shown in FIG. 2, the difference a2 between the hair length a3 of the side 7 of the brush part 1 opposite to the hair length a1 of the side 6 of the brush part 1 is 2 mm. More than 20 mm is desirable. Similarly, when the brush part 1 has an inclination, as shown in FIG. 3, the difference b2 between the length b3 of the side 9 of the brush part 1 opposite to the length b1 of the side 8 of the brush part 1 is 2 mm or more and 20 mm or less are desirable. When the similarity ratio between the area of the bristles 12 of the brush part 1 where the brush part 1 does not have an inclination and the connection opening part 5 of the base part 2 is 1: 1, the joint opening part 5 of the base part 2 is used as an axial center line. The area is the same as the projected area on the perpendicular plane. Depending on the purpose of use, the connection opening 5 of the base part 2 is projected on the plane that intersects the polygonal shape or the curved shape having the concavo-convex part or the combination of a curve or a straight line, or the hair end surface 12 of the brush part 1 perpendicular to the axis. The area of the projected view 13 can be changed. That is, for example, the projection 13 in which the tip surface 12 of the brush portion 1 is projected onto a vertical plane intersecting the axial center line is a polygonal shape or an uneven portion of the connection opening 5 projected onto the plane perpendicular to the axial center line. If the curve shape or the shape combining the curve or straight line is maintained, the similarity ratio can be changed to increase or decrease the area of the hair end surface.

16 (I) and (II) are cross-sectional views of the inside of the base 2. As shown in FIG. 16I, the base part 2 has a connection opening 4 and a connection opening 5, and the inside of the opening of the base part 2 from the connection opening 4 toward the connection opening 5 inside the base part 2. The base 2 is manufactured with a taper so as to be small. As a result, when the brush part 1 is formed by filling the base part 2 with hair and bonding the adhesive part 16 with an adhesive or the like, the gap between the connection opening 5 of the base part 2 and the brush part 1 is reduced, and the brush The hair planted in the part 1 is held in the base part 2 more so that the shape of the brush part 1 can be maintained more stably.
As shown in FIG. 16 (II), the taper inside the base part 2 may be tapered from the connection opening 5 of the base part 2 to the position of the distance e. In that case, the distance e from the connection opening 5 of the base part 2 is desirably 2 mm or more and 50 mm or less.

The base part 2 is made of a plastic material or metal having a connection opening 5 having a polygonal shape. As the plastic material, ABS resin or AS resin is used in the case of a thermoplastic resin, and polyurethane resin or the like is used in the case of a thermosetting resin. Such a plastic material is molded into the base part 2 using an injection molding machine, a cutting machine or the like. By manufacturing the base portion with a plastic material, a curved shape having a polygonal shape of the brush portion or an uneven portion, or a shape combining curves and straight lines is formed more sharply. Next, hair is planted in the base part 2, and the hair constituting the brush part 1 and the base part 2 near the bonding position 16 of the base part of the brush part 1 close to the connection opening 5 of the base part 2 by known means, Are bonded by an adhesive or the like.

As shown in FIG. 8, since the brush portion 1 is inclined, the area of the hair end surface 12 of the brush portion 1 that is in contact with the face becomes longer than that of the brush portion 1 of the connection opening 5 of the base portion 2 shown in FIG. 6. When the area is larger than h and width w, the tip of the brush portion 1 comes into close contact with the skin, compared to the case where the tip is like a brush like conventional makeup and face washing brushes. As a result, in the case of makeup, a wide area of the face such as a cheek or forehead can be applied finely and easily. When used for face washing, when washing a wide area of the face such as the cheek or forehead, effective washing can be obtained even with a light force.

As FIG. 8 shows, it becomes easy to make up or wash the details around the nose of the face by using the side 11 of the hair tip of the brush part 1. When the side 11 at the tip of the hair tip of the brush portion 1 has been bent over a long period of use, the life of the brush is extended if a side other than the side 11 at the tip of the polygonal hair tip of the brush portion 1 is used. .

As shown in FIG. 8, the difference in the distance a1 of the side 7 of the brush part 1 and the distance a3 of the side 6 of the brush part 1 makes it possible to adjust the feeling of use when using a single brush. When the length a1 of the side 7 is made longer than the length a3 of the side 6, the hair tip side 11 becomes softer because the degree of freedom of the hair on the side 7 having the long distance a1 is greater. When the length a3 of the side 6 is shorter than the length a1 of the side 7, the degree of freedom of the hair on the side 6 is less than the degree of freedom of the side 7, so that the softness of the tip side 10 is soft Less than 11 softness. In this way, it is possible to change the comfort of using a single brush.

As shown in FIG. 9, when the brush part 1 is viewed from the side, the connection opening 5 of the base part 2 has an inclination, so that the length c of the side 7 of the brush part 1 and the length 6 of the side 6 of the brush part 1 are obtained. d is different. Therefore, since the length c of the side 7 is short, the degree of freedom of the hair on the side 7 is reduced, so the softness of the hair tip side 11 is reduced. Since the length d of the side 6 is longer than the length c of the side 7, the degree of freedom of the hair on the side 6 is increased, and the softness of the hair tip side 10 is increased. While having the flat brush surface 12 as described above, a brush having a different feeling of use is obtained depending on the positions of the hair tip side 11 and the hair tip side 10 of the brush portion 1. In the case of FIG. 9, a planar polygon 55 (not shown) having an area S <b> 11 formed by the joint opening 5 of the base portion 2 is inclined with respect to the axial center line. A projection projected onto a plane that intersects perpendicularly (polygon having an area S12 (not shown)) is a polygon 56 having a different area (S11> S12) that is not similar. Further, assuming that the area of the polygon 57 in the plane of the hair tip surface 12 formed by the hair tip of the brush portion 1 is S13, the projection (not shown) is projected onto the plane perpendicular to the axial center line. The polygon of area S14 is a polygon 58 having the same area (S13 = S14) and the same shape. Also in this case, the similarity ratio with the polygon 56 of the area S12 (not shown) of the projection projected onto the plane perpendicular to the axial center line of the hair tip surface 12 formed by the hair tip of the brush portion 1 has a one-to-one relationship. Yes, that is, polygons having the same area (S12 = S14) and the same shape.

The shapes of the brush part 1, the base part 2, and the handle part 3 as shown in FIG. 1 can be changed depending on the purpose of use. Embodiments of the brush part 1 and the base part 2 different from the form shown in FIG. 1 are shown in FIGS. 12, 13, and 14 as representative examples.

As shown in FIG. 12 (I), when the bristle face 12 of the brush part 1 and the joint opening 5 of the base part 2 are one polygonal, triangular, the width of the face, the straight line of the bristle Not only can the edges be obtained, but the hair tips of the triangular vertices 20 can be used as point brushes. As shown in FIG. 12 (II), when the bristles surface 12 of the brush part 1 and the connection opening 5 of the base part 2 are one polygonal, pentagonal, the width of the surface is further obtained, and the brush When the pentagon of the hair tip surface of the part 1 is inclined, one vertex 21 of the pentagonal brush part 1 can be used more effectively as a point brush.

As shown in FIG. 12 (III), the shape of the brush portion 1 projected onto the plane perpendicular to the axis of the brush portion 1 is similar to the shape of the joint opening 5 between the base portion 2 and the brush portion 1. Since the surface has two surfaces 30 and 31, the surface 30 can be used for adjusting the eyebrows, and the surface 31 can be used for other facial parts. (IV) of FIG. 12 is a figure at the time of making the connection opening part 5 of the nozzle | cap | die part 2 and the hair face 12 of the brush part 1 into a hexagon. (V) of FIG. 12 is a figure at the time of making the connection opening part 5 of the nozzle | cap | die part 2 of the brush part 1, and the hair face 12 of the brush part 1 into the star shape comprised by the polygon. An octagon may be sufficient as the polygon of the connection opening part 5 of the nozzle | cap | die part 2 of the brush part 1, and the hair face 12 of the brush part 1. FIG.

FIG. 13 shows some examples of embodiments in the case of a curved shape having an uneven portion. By providing the concave portion, a portion having a small curvature radius of the curved portion that becomes the convex portion can be formed, so that a wide range of the face such as a cheek or forehead to details around the nose can be covered with a single brush. FIGS. 13 (I) and (II) are examples in which the projection shape with one recess is a heart shape. By changing the curvature of the curvature portion that becomes a convex portion as shown in the figure even at one concave portion, a brush that reaches the details around the nose can be manufactured.
As shown in FIG. 13 (III), the connection opening 5 of the base portion 2 and the hair end surface 12 of the brush portion 1 are flower-shaped brushes configured in a shape combining curves having uneven portions. By having a curved portion with a small curvature on the hair tip surface 12 of the brush portion 1, the hair tip reaches the details such as around the nose.
As shown in FIG. 13 (IV), the connection opening 5 of the base part 2 and the hair end surface 12 of the brush part 1 are clover-shaped brushes configured in a combination of curves having uneven portions.

As shown in FIG. 14 (I), the connection opening 5 of the base part 2 and the hair end surface 12 of the brush part 1 are heart-shaped brushes configured in a combination of curves and straight lines. By using a smooth curve formed by the curved portion by this single line and an acute corner portion formed by the intersection of the straight line portions, it is possible to cope with makeup and face washing of various parts of the face. FIG. 14 (II) is a star-shaped brush in which the connection opening 5 of the base portion 2 and the hair end surface 12 of the brush portion 1 are configured in a shape combining curves and straight lines. FIG. 14 (III) shows a cat face-shaped brush in which the connection opening 5 of the base part 2 and the hair end surface 12 of the brush part 1 are formed in a shape combining curves and straight lines.

As shown in FIGS. 15 (1) and 15 (2), the base part 2 made of a plastic material has a planar shape of the second joint opening part 4 with the handle part 3 of FIG. 1 and the brush part 1. Since it is possible to manufacture even when the planar shape of the joint opening 5 is different, the joint opening between the brush part 1 and the base part 2 is emphasized for ease of holding the second joint opening 4 with the handle 3 as a circle. It becomes possible to make the shape of the hair face 12 of the part 5 and the brush part 1 into the shape which combined polygonal shape or the curved shape which has an uneven | corrugated | grooved part, or a curve and a straight line. Although this brush is a makeup and facial cleansing brush, there is no problem even if it is used only for cosmetics or only for facial cleansing.
