As shown in FIG. 2, the cosmetic application body of the present invention is attached to the tip of a support shaft 2 suspended from a lid 3 that can be attached to the container body 4 of the cosmetic container. The cosmetic container of the present embodiment is of a type in which an ironing portion 41 is provided in the neck of the container body 4 to squeeze out excess cosmetics attached to the coating body 1, but the embodiment of the cosmetic container Is not limited to this. Further, the cosmetic coating body of the present invention is not limited to the one attached to the lid portion 3 via the support shaft 2, and the fixing portion 11 is attached to a separately provided grip portion to form an independent coating body or fixed. The portion may be used as an independent coating body as a direct grip portion. Hereinafter, the coated body 1 of the present invention will be described in detail.

As shown in FIG. 1, in the coating body 1 of the present invention, a fixing portion 11 is formed so as to be attachable to a support shaft 2, a base portion 12 extending from the fixing portion 11, and a tapered portion extending further from the base portion 12. 13 and.

The fixing portion 11 is formed in a columnar size capable of being inserted into the hole portion 21 having an opening formed from the tip of the support shaft 2, but if the coating body 1 can be fixed to the support shaft 2, The fixing method is not limited to insertion.

A rod-shaped base 12 extends from the tip of the fixed portion 11. The base portion 12 of the present embodiment is formed in a columnar shape unless a portion diagonally cut out for forming the coating surface 14 is taken into consideration, but the shape is not limited to this, as shown in FIGS. 3 to 5. In addition, it may be an elliptical column or another polygonal column such as a hexagonal column. In each of FIGS. 4 and 5, the base 12 is a hexagonal columnar, but the position of the apex angle thereof is formed with a deviation of about 30 ° in the circumferential direction.

A tapered portion 13 whose diameter is reduced so as to taper is extended to the tip of the base portion 12. The tapered portion 13 of the present embodiment is formed in a conical shape if a notched portion is not taken into consideration, but the shape is not limited to this and may be an elliptical cone as shown in FIG.

That is, the coated body 1 of the present invention is formed in a pencil shape by combining the base portion 12 and the tapered portion 13 if the diagonally cut out portion is not taken into consideration. Here, "pencil-shaped" means that a tapered portion 13 having a reduced diameter is extended on a base portion 12 having a columnar or polygonal columnar shape having the same diameter, and the tapered portion 13 is along an inclined surface of the tapered portion 13. It means that the contour shape is formed to be linear. Then, from the side surface of the base portion 12 having such a shape to the side surface on the opposite side of the tapered portion 13, a cut portion formed when an oblique cut is made constitutes the coating surface 14. Here, the "opposite side surface" means an inclined surface of the tapered portion 13 located below the side surface of the base portion 12 which is the back side with respect to an arbitrary portion of the side surface of the base portion 12. Here, "diagonally cut out" means that if the shape is finally formed in a diagonally cut out shape, it is not always necessary to form the notch in the manufacturing process, and other manufacturing such as general injection molding is performed. You may use the method.

As described above, the coating body 1 is formed in a diagonally cut shape from the front side surface 121 of the base portion 12 to the back side surface 131 of the tapered portion 13, and the coating surface 14 of the portion corresponding to the cut end is tapered with the base portion 12. A continuous inclined surface is formed over both of the portions 13. The contour line of the coated surface 14 is formed in a substantially U-shape of a gentle parabola as a whole on the base portion 12 side when viewed from the front, whereas on the tapered portion 13 side, the tip portion 15 of the coated body 1 is formed. The vicinity is formed in a substantially V shape that bends in an arc shape. Due to the shape of the coating surface 14, sufficient cosmetics can be retained on the base 12 side, and the taper portion 13 having a sharper shape can be appropriately applied to a fine portion.

Further, in the present embodiment, the extension line of the axis of the base 12 is formed so as to intersect with the coating surface 14. Further, the tip portion 15 of the coating body 1 is formed so as to be biased toward the back surface side surface 131 opposite to the coating surface 14 with respect to the extension line of the axis of the base portion 12. It is preferable that the tip portion 15 is formed so as to have an arc shape with slightly rounded corners rather than the shape of the tip portion 15 when it is notched diagonally.

The position of the tip portion 15 of the coating body 1 is an element that affects the inclination angle of the coating surface 14 and the curvature of the arc of the tip portion 15, and as in the present embodiment, with respect to the extension line of the axis of the base portion 12. By forming the coating surface 14 so as to be biased toward the back surface side surface 131 on the opposite side to the coating surface 14, the inclination angle of the coating surface 14 and the curvature of the arc of the tip portion 15 are optimized, which is preferable.

The inclination angle θ1 of the coating surface 14 with respect to the vertical direction is preferably in the range of 8 to 20 °, more preferably 10 to 20 °. The radius of curvature R of the tip portion 15 is preferably in the range of 0.2 to 0.8 mm, more preferably 0.4 to 0.6 mm in front view. Further, the angle θ2 between the coated surface 14 and the inclined surface of the tapered portion 13 is preferably in the range of 15 to 35 °, more preferably 20 to 30 °. Here, the "inclined surface of the tapered portion 13" means the back surface side surface 131 opposite to the coated surface 14.

As described above, a sufficient amount is obtained by forming the coating surface 14 over both the base portion 12 and the tapered portion 13 and further setting the inclination angle of the coating surface 14 and the radius of curvature of the tip portion 15 as described above. It is possible to secure the area of the coating surface 14 to which the cosmetic of the above can be applied. Although the coating surface 14 of the present embodiment is formed on a flat surface, it does not necessarily have to be formed completely flat, and may be slightly concave or convex.

In addition, by making the tip side a tapered portion 13 and then cutting it diagonally, the tip portion 15 has a fineness and sharpness suitable for fine work, so that finishing that requires delicate work can be done at the tip. This can be done appropriately in section 15.

Further, by making the tip side a tapered portion 13 and forming it into a shape that is notched diagonally, it is possible to secure the thickness required for maintaining the rigidity in the vicinity of the tip portion 15, which enables the tip to be applied at the time of application. The power of the hand can be appropriately transmitted to the part 15, and the cosmetic can be appropriately spread.
