In Patent Document 1, a coating film is provided on the inner surface of the fitting portion so that the outer wall of the sleeve comes into contact with the coating film, so that the rotary feeding operation can be facilitated. In Patent Document 2, a plurality of support protrusions are provided on the inner peripheral surface of the fitting portion to regulate lateral runout of the feeding structure. In Patent Document 3, a contact portion with which the side surface of the sleeve abuts is provided on the inner peripheral surface of the fitting portion at a position slightly lower than the mouth to prevent scratches at a position visible from the outside of the side surface of the sleeve.

The above-mentioned patent documents have the effects of smoothing the rotation operation, regulating the lateral shake, and preventing the occurrence of scratches due to the lateral shake. However, due to the structure that holds the end of the feeding structure, it is difficult to prevent the occurrence of lateral vibration itself, and lateral vibration occurs when the container is shaken, and the sleeve and the fitting part hit each other, making it a hard object. There was a rattling noise that occurred when they hit each other. This rattling noise spoiled the luxury of the cosmetic container.

In order to solve the above-mentioned problems, the present invention includes a feeding mechanism 10 that holds the rod-shaped cosmetics 1 and slides the rod-shaped cosmetics 1 up and down by the relative rotation of the sleeve 3 exposed to the outside and the connecting portion 41 at the lower end. , The feeding structure A in which the O-ring 11 having elasticity and sliding contact is arranged between the sleeve 3 and the relative rotating portion of the connecting portion 41, and the cap covering the upper portion of the feeding structure A are detachably fitted.

Line contact with the outer wall of sleeve 3. As a result, although the sliding resistance of the sleeve 3 and the exterior body B during relative rotation is small, the sleeve 3 is supported by the shaft core 15 and the lateral runout of the feeding structure A is suppressed.

As described above, in the present invention, since the sleeve 3 is supported by the abutting portion 60 of the abutting cylinder 6 on the axial center 15 of the exterior body B, the feeding structure A is suppressed from lateral vibration, and the outer wall of the sleeve 3 is elsewhere. It doesn't hit and doesn't make a rattling noise. Further, since the tip 61 of the contact portion 60 is in line contact with the outer wall of the sleeve 3, the sliding resistance during relative rotation is small, and the container is optimally adjusted by the O-ring 11 in the feeding structure A. It does not affect the operability.

Further, the contact cylinder 6 is provided with a deformable bellows-shaped contact portion 60, and when the contact cylinder 6 is sandwiched between the middle cylinder 5 and the main body cylinder 9, the inner diameter of the contact portion 60 is narrowed.
