  As shown in FIG. 1 to FIG. 3, a cosmetic container 100 with an application body includes a container main body 1 and a tip tube 2 constituting the container, a batting 3 housed in the container main body 1, a container body 1 and a tip tube. 2 schematically includes a relay core 4 housed in 2, an application body 5 attached to the tip of the front tube 2, and a cap 10 detachably attached to the container body 1 so as to cover the application body 5.

  The container main body 1 is formed of PP or the like, for example, and is configured in a tapered stepped cylindrical shape as shown in FIGS. The container main body 1 accommodates a batting 3 made of, for example, polyester impregnated with liquid cosmetic material in a cylindrical hole on the rear side of the stepped portion 1a, and the rear end opening is closed by attaching a tail plug 7. It has been.

  The front tube 2 is formed of PP or the like, for example, and the rear half 2a is formed in a cylindrical shape, and the front side thereof is a flat cylindrical portion 2b. The flat cylindrical portion 2b has an outer surface whose diameter is enlarged via a stepped portion 2c with respect to the cylindrical second half portion 2a, and has a rectangular cross section (cross section orthogonal to the axial direction). Both the outer surface of the long-diameter side and the short-diameter side of the rectangular tube shape are tapered to become flattened and gradually become smaller while curving somewhat toward the tip. The flat cylindrical hole of the flat cylindrical part 2b and the circular cylindrical hole of the rear half part 2a have a flat cylindrical hole whose diameter on the longer diameter side of the rear end of the flat cylindrical hole coincides with the diameter of the circular cylindrical hole. As shown in FIG. 3, the rear end side of the hole has a configuration in which it is connected to a circular cylindrical hole through a step 2g. The stepped portion 2g functions to prevent the relay core 4 from moving forward.

  In the rear half 2a of the front tube 2, a spring portion 2h is formed by providing a notch 2i that is U-shaped in radial direction (in the vertical direction in FIG. 3) and communicates with the inside and outside. The spring portion 2h is for preventing the relay core 4 from moving backward. The left side in the drawing is used as a tip portion and the right side in the drawing is cantilevered so as to have elasticity in the radial direction. Provided.

  As shown in FIGS. 2 and 3, the opening 2x at the tip of the front tube 2 is used as a container outlet, and protrudes forward of the opening edge 2d on the short diameter side (vertical direction in FIG. 3) on the short diameter side of the opening edge. A pair of protruding portions 2e are provided to face each other. The protrusion 2e is provided with a support hole 2f for rotatably supporting the application body 5 in the minor axis direction.

  The application body 5 is for applying the liquid cosmetic material to the application portion, and is formed of, for example, ABS or the like and configured in a disk shape. The disc-shaped application body 5 includes a shaft portion 5a that protrudes outward in the axial direction at the position of the axial center. The thickness of the outer peripheral portion of the disc-shaped application body 5 is set to a thickness suitable for drawing a thin line such as an eyeline. In addition, the shape of the application body 5 is not limited to this, In short, what is necessary is just a disk shape. The application body 5 is disposed at the outlet 2x of the front tube 2 and rotatably supported by the front tube 2 when the shaft portion 5a enters the support hole 2f of the front tube 2.

  The relay core 4 exhibits a capillary phenomenon, and has a shape corresponding to (matching) the cylindrical hole of the front tube 2 as shown in FIGS. 3 and 4. A portion of the relay core 4 on the front end side of the step portion 4d to be abutted against the step portion 2g of the front tube 2 is a flat shape portion 4x having a flat shape, and a rear side of the step portion 4d is a round bar shape having a circular cross section. Extend backwards. The front end portion 4 a of the flat portion 4 x of the relay core 4 is a portion for contacting the application body 5, and the rear portion side portion of the relay core 4 is a portion for entering the batting 3. The rear side of the portion entering the batting 3 is a frustoconical frustoconical portion 4y in order to make it easier to enter the batting 3. Further, a concave portion 4c is formed in an annular shape at the center of the relay core 4 so that the spring portions 2h, 2h of the front tube 2 enter and engage in the axial direction.

  The relay core 4 having such a configuration is formed by the following pultrusion molding. Specifically, for example, nylon fibers or polyester fibers are focused, and the fiber bundle is passed through a tank containing an adhesive resin so that the fiber bundle is impregnated with the adhesive resin, and the adhesive resin is impregnated. The fiber bundle is drawn from a mold having a hole having a circular cross section to obtain a round bar-shaped molded product, that is, a porous fiber body. Here, the moving speed of the fiber bundle is controlled so that the adhesive resin does not reach the axis of the fiber bundle but reaches only a predetermined diameter.

  Next, the fiber bundle hardened in a round bar shape with the adhesive resin is polished using, for example, a grinder so as to have the shape shown in FIG. Here, the round bar-like portion excluding both ends remains in a hard state because a portion solidified by the adhesive resin remains even after polishing.

  On the other hand, since the truncated truncated cone part 4y becomes thinner toward the rear end, the adhesive resin is scraped off around the rear end part 4b of the truncated truncated cone part 4y. As shown in FIG. Will be in a disjointed state.

  Further, since the flat shape portion 4x is flat, at the front end portion 4a, the adhesive resin is scraped off and the fibers are slightly scattered in the same manner as the rear end portion 4b.

  Next, unraveling is performed on the tip portion 4a. In this unraveling process, a gear-like disk with high hardness having a large number of irregularities on the outer peripheral surface is prepared. Specifically, a disk in which fine irregularities are continuously arranged along the outer peripheral surface is prepared. And the front-end | tip part 4a is pressed toward the unevenness | corrugation of the outer peripheral surface of a rotating disc, and the front-end | tip part 4a is loosened. By performing the loosening process after polishing in this way, the tip portion 4a is in a loosened state as shown in FIG. In addition, for example, a hard belt that has a large number of fine irregularities arranged on the surface and moves along an elliptical track is prepared, and the tip 4a is pressed against the irregularities of the moving belt to loosen the tip 4a. Also good.

  And the relay core 4 of such a state is inserted in the cylinder hole of the front cylinder 2 from the front end side, as shown in FIG. Since the relay core 4 and the cylindrical hole of the front tube 2 are flat, the relay core 4 and the front tube 2 are not rotatable. In the front tube 2 in which the relay core 4 is inserted, the cylindrical rear half portion 2 a is press-fitted into the cylindrical tip portion of the container body 1, and the stepped portion 2 c is formed on the tip surface of the container body 1. At the end, the container body 1 is mounted.

  At this time, the outer surface of the distal end portion of the spring portion 2h of the front tube 2 is pushed by the inner peripheral surface of the container body 1 to bend inward, and the inner ends of the spring portions 2h and 2h enter the recess 4c of the relay core 4, While the relay core 4 is prevented from moving backward, the stepped portion 4d of the relay core 4 hits the stepped portion 2g of the front tube 2, and the relay core 4 is prevented from moving forward. That is, the relay core 4 is attached to the front tube 2 so as not to move in the axial direction. In this state, the rear side portion of the relay core 4 is in a state of being inserted into the batting 3.

  Further, in this state, the tip 4 a of the relay core 4 is located in the tip of the front tube 2, and the outer peripheral surface 5 b of the disc-shaped application body 5 enters the tip 4 a in the loosened state of the relay core 4. And in contact.

  In the cosmetic container 100 with the application body configured as described above, the liquid cosmetic impregnated in the batting 3 is sent out to the tip portion 4a through the relay core 4 by capillary action, and the tip portion of the relay core 4 It is transferred to the outer peripheral surface 5b of the application body 5 in contact with 4a. And a user can draw the line of liquid cosmetics by removing the cap 10, applying the application body 5 to an application part, moving a container along an application part, and rotating the application body 5. FIG.

  At this time, as described above, the tip end portion 4a, which is a portion of the relay core 4 that contacts the application body 5, is in a loosened state. Specifically, the rotation of the disk-shaped application body 5 is hindered. It is in a state where it is loosened to such an extent that a sufficient amount of liquid cosmetic material for application can be sent to the application body 5 by capillary action. For this reason, according to the cosmetic container 100 with an application body of this embodiment, the application body 5 rotates favorably and can draw a beautiful line.

  Here, it is preferable that the axial direction length (unwinding length) of the distal end portion 4a of the relay core 4 in the loosened state is 1.5 mm to 2.5 mm.

  According to the experiment of the present inventor, the length in the axial direction of the distal end portion 4a in the loosened state of the relay core 4 is 1.5 mm (Example 1), 2.0 mm (Example 2), 2.5 mm ( In the case of Example 3), the application body 5 rotates well, and a sufficient amount of liquid cosmetic material for application can be sent to the application body 5 by the capillary force of the loosened tip portion 4a. On the other hand, when the length in the axial direction of the distal end portion 4a in the loosened state of the relay core 4 is 0.5 mm (Example 4) and 1.0 mm (Example 5), the distal end portion 4a in the loosened state. The capillary force is substantially the same as in the first to third embodiments, but the length of the tip portion 4a in the loosened state is short because the axial direction length is short, and the rotation of the application body 5 is different from those in the first to third embodiments. . Moreover, when the axial direction length of the front-end | tip part 4a of the state which the relay core 4 was loosened is 3.0 mm (Example 6) and 3.5 mm (Example 7), the application body 5 is Example 1-. However, the capillary force of the loosened tip 4a is weaker than in the first to third embodiments. Accordingly, the axial length of the distal end portion 4a of the relay core 4 in the loosened state is preferably 1.5 mm to 2.5 mm.

  The present invention has been specifically described above based on the embodiment. However, the present invention is not limited to the above embodiment. For example, in the above embodiment, the container body 1 and the front tube 2 are separate parts. However, it may be a one-piece container.

  Moreover, in the said embodiment, the batting type which accommodates the batting 3 impregnated with liquid cosmetics in the container main body 1, and supplies liquid cosmetics from the batting 3 to the application body 5 via the relay core 4 is employ | adopted. However, there is no batting 3 and the liquid cosmetic is directly filled in the container body 1 and the direct liquid type is used to supply to the coated body 5 through the relay core 4 while controlling the flow rate of the liquid cosmetic by the bellows structure. Also good.

  Furthermore, in the above-described embodiment, as a particularly preferable, the application body 5 has a disk shape, but instead of a spherical shape, for example, the spherical application body has a single axis as a fulcrum as in the case of a disk-shaped application body. The present invention can also be applied to a case where the liquid cosmetic is applied to a portion to be applied by a spherical application body while being rotatably supported.
