Stick-shaped cosmetic material cartridge

Abstract

To improve a quality without damaging a delivery function. A rear inner cylinder 12 is housed in an outer cylinder 10 in a state where rotation is possible and moving in the axial direction is impossible. A front inner cylinder 13 is connected to the rear inner cylinder 12 in a state where moving in an axial direction is possible and rotation is impossible, and housed in the outer cylinder 10 energized to a rear side by an energizing means 16. A male thread 14f of a screw rod 14 supporting a stick-type cosmetic material M and provided with the male thread 14f on the outside is screw-fitted to a female thread 13x inside the inner cylinder 13. Thus, when a torque is applied to the rear inner cylinder 12 from its rear side, the inner and outer cylinders are rotated relatively and the screw rod 14 is moved forward and backward smoothly to make the cosmetic material M appear and disappear. When a shock is acted to stick-type cosmetic feed-out container 100 to which a cartridge 1 is mounted, a state where the torque is reliably applied to the rear inner cylinder 12 to its rear side without moving in an axial direction, and the front inner cylinder 13 moves forward against the biasing means 16 with the screw rod 14 leaving the rear inner cylinder 12. By the cushioning operation of the energizing means 16, the impact is absorbed to prevent the cosmetic material M from getting out and being broken.

Description

technical field [0001] The invention relates to a stick-shaped cosmetic material box capable of leading out and introducing a stick-shaped cosmetic material from the box. Background technique [0002] In the past, as a rod-shaped cosmetic material export container, such a rod-shaped cosmetic material export container is known: the rear end of the front tube and the front end of the shaft tube are connected in a manner that can rotate but cannot move in the axial direction, and the inside A spiral cylinder with a female thread and a plurality of strip-shaped protrusions in the axial direction on the outside in the circumferential direction is inserted into the shaft cylinder, so that the interior of the shaft cylinder is provided with a plurality of protrusions in the axial direction along the circumference A plurality of elongated grooves on the top are engaged with the protrusions on the outside of the spiral tube, so that the spiral tube can be accommodated inside the shaf...

Problems solved by technology

[0006] However, in recent years, there has been a higher quality requirement for the latter stick-shaped cosmetic material box, and it is required to adopt a mechanism that absorbs shocks and vibrations and prevents the stick-shaped cosmetic material from falling off and breaking like the former stick-shaped cosmetic material export container, but such a mechanism has not yet appeared.
