While the teeth 8d and the protrusions 7d of the female screw member 7 are repeatedly engaged (disengaged), a click feeling (resistance feeling) is given to the user each time the ratchet teeth 8d and the protrusions 7d are engaged with each other. The piston 9 advances cosmetic L is pushed out distally, are emergent use state from the opening of the distal end of the cartridge tube 5. Thus, the degree of relative rotation and the degree of advancement of the piston 9 are sensed by the click feeling given to the user, and an appropriate amount of cosmetic L can be discharged.

  Further, in the state where the moving body 6 is positioned at the forward / backward limit, when the relative rotational force to be further advanced is applied and an excessive rotational torque is applied, specifically, the protruding portion of the cylindrical body 4 When excessive rotational torque acts on the second protrusion 4h of 4b via the knurl 7b of the female screw member 7, the protrusion 4b has an arc shape in the axial direction. Is bent so as to fall inward with the bottom as a fulcrum, releasing excessive rotational torque and functioning as a clutch. For this reason, an overload does not act on components, and damage to components can be prevented.

  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 protruding portion 4b of the cylindrical body 4 is used as a clutch. In order to make it function, it is configured to be interrupted along the circumferential direction to form an arc shape when viewed in the axial direction, but even if it is configured as an annular shape when viewed in the axial direction, the effect of the present invention that there is no need to forcibly remove the mold is provided. Can be obtained.

  Alternatively, the first protrusion 4e and the second protrusion 4f may be interchanged to replace their functions.

  Further, the protruding portion 4b is protruded in the opposite axial direction, the first cosmetic cartridge is disposed on one end side of the container body 2 and the second cosmetic cartridge is disposed on the other end side, The first cosmetic cartridge may be engaged by the first protrusion, and the second cosmetic cartridge may be engaged by the second protrusion of the protruding portion protruding in the opposite direction.

  In the above-described embodiment, the cosmetic L is a soft stick-like cosmetic as being particularly suitable. However, the cosmetic L can also be applied to a liquid or semi-solid cosmetic. In this case, the ratchet It is preferable that the cosmetic can be moved forward and backward together with the moving body 6 without providing a mechanism, and it is more preferable to use a click mechanism instead of the ratchet mechanism. It is also possible to use mud and gel cosmetics by reducing the opening at the tip of the cartridge cylinder.
