  Thus, in the stick-shaped cosmetic material supply container described in the above publication, the cylinder moves forward / backward during the clutch operation, but the male screw of the rod-shaped body is screwed into the female screw of the cylinder. There is a problem that the stick-shaped cosmetic material held in the stick-shaped cosmetic material holding portion at the tip of the stick-shaped body enters and exits from the opening at the tip of the container, and looks bad.

  Therefore, an object of the present invention is to provide a bar-shaped cosmetic material feeding container that does not enter and exit from the opening at the tip of the container during clutch operation and is improved in appearance.

  The stick-shaped cosmetic material feeding container according to the present invention includes a cylindrical container having a container front part and a container rear part, a non-rotatable around the axis with respect to the container front part, and movable in the axial direction. A movable body that is supported and provided with a male screw on the outer peripheral portion, and a female screw member that is rotatable about an axis with respect to the front portion of the container and has a female screw that is screwed to the male screw on the inner peripheral portion. This is a stick-shaped cosmetic feeding container in which a screw-shaped part composed of a male screw and a female screw works by the relative rotation of the container front part and the container rear part so that the mobile body advances and retreats so that the bar-shaped cosmetic protrudes and disappears from the opening at the container tip. The rear portion of the container has a first meshing portion on the inner peripheral portion thereof, and the female screw member is provided on the rear end side of the container and is engaged with the first meshing portion around the axis around the axis of the rear of the container. And a second meshing portion coupled to be rotatable in synchronization with each other, and provided on the front side of the second meshing portion. Provided between the female screw, which is prevented from moving forward, and the female screw and the second meshing portion in the axial direction, the second meshing portion and the first meshing portion can be meshed around the axis during the relative rotation. And a spring portion that urges the second meshing portion toward the rear so that when the excessive torque acts on the moving body, the spring portion is retracted so that the axis of both meshing portions is It is characterized in that the meshing is released.

  According to such a bar-shaped cosmetic delivery container, the female screw member is a female screw, a spring part, and a container that are screwed with a male screw provided on the outer peripheral surface of the movable body from the front side to the rear side in the axial direction. A second meshing portion urged rearward by a spring portion so as to enable meshing about the axis with the first meshing portion of the container rear portion at the time of relative rotation between the front portion and the container rear portion; When the container and the container rear part are rotated relative to each other, the first meshing part of the container rear part and the second meshing part of the female screw member mesh with each other around the axis, and the female screw member can rotate synchronously around the axis with the container rear part. Connected to the front of the container, the male screw of the movable body that is not rotatable about the axis and movable in the axial direction, and is rotatable about the axis with respect to the front of the container. The female screw member of the female screw member connected so as to be able to rotate synchronously works. The mobile body advances and retreats, and the bar-shaped cosmetic supported on the tip of the mobile body appears and disappears from the opening at the tip of the container. On the other hand, the mobile body reaches the forward limit / retract limit and further moves the mobile body further. When excessive torque is applied to the moving body by applying a rotational force, the female screw of the female screw member that is prevented from moving forward does not move in the axial direction, and the spring portion of the female screw member is degenerated, and the second of the female screw member. The meshing portion of the female screw member moves forward against the urging force of the spring portion of the female screw member, and the meshing about the axis of both the meshing portions is released. Subsequently, the second meshing portion of the female screw member is the spring of the female screw member. By retreating by the urging force of the part, the meshing of both meshing parts returns at the meshing position adjacent to the periphery of the axis, and functions as a so-called clutch. For this reason, even if an excessive torque is applied to the moving body, no overload is applied to the component, the component is prevented from being damaged, and the female screw of the female screw member does not move in the axial direction during the clutch operation. Therefore, there is no entry / exit of the bar-shaped cosmetic supported by the moving body through the opening at the tip of the container, and thus the appearance is improved. Further, when an impact or vibration is applied, for example, by dropping the stick-shaped cosmetic feed container, the shock or vibration is absorbed by the buffering action of the spring portion of the female screw member, thereby protecting the stick-shaped cosmetic.

  Here, the female screw member is provided with a flange on the outer peripheral surface on the rear side from the front end surface and on the front side in the axial direction in the axial direction, and the rear part of the container front part is inserted into the front part of the rear part of the container. The front portion of the female screw member from the flange portion enters the insertion portion of the container front portion, and the female screw member abuts against the rear end of the insertion portion of the container front portion so that the female screw member advances. Is preferably prevented.

  When such a configuration is adopted, the rear part of the front part of the container is inserted into the front part of the rear part of the container to be an insertion part, and the front end of the female screw member is brought into contact with the rear end of the insertion part of the front part of the container. The insertion length of the insertion part at the front part of the container with respect to the rear part of the container is increased as compared with the configuration in which the advancement of the female screw member is prevented by contact. For this reason, it becomes difficult to bend the front part of the container in the direction orthogonal to the axial direction, and the rod-shaped cosmetic material is further protected.

  Further, when the female screw member is provided with a rotation resistance applying portion that applies rotation resistance at the time of relative rotation in a portion on the front side of the flange portion, good rotation resistance is provided at the time of relative rotation.

  Further, if the female screw member is an integrally molded product, the manufacturing cost can be reduced.

  As described above, according to the present invention, the clutch function is exhibited when the moving body reaches the forward limit / reverse limit and a relative rotational force is applied to further advance the moving body and an excessive torque acts on the moving body. This prevents the parts from being damaged and improves the appearance by eliminating the stick-shaped cosmetics coming in and out of the opening at the tip of the container during the clutch operation. It is possible to protect cosmetics.
