Stick-shaped cosmetic material cartridge

Abstract

In the rod-shaped cosmetic material box of the present invention, the rear inner cylinder (12) is accommodated in the outer cylinder (10) in a manner that can rotate but cannot move in the axial direction, and the front inner cylinder (13) can move in the axial direction but cannot rotate. It is connected with the rear inner cylinder (12) and applied force on the rear side by means of a force applying device (16) and is accommodated in the outer cylinder (10). The internal female thread (13x) of the front inner cylinder (13) is screwed with support A rod-shaped cosmetic material (M) and a male thread (14f) structure of a screw (14) having a male thread (14f) on the outside. Therefore, when a rotational force is given to the rear inner cylinder (12) from the rear side, the inner and outer cylinders will rotate relative to each other, and the screw (14) will advance and retreat smoothly so that the cosmetic material (M) is smoothly exported and introduced, and when the box ( 1) When the rod-shaped cosmetic material outlet container (100) has an impact action, the rear inner cylinder (12) can maintain a state of being stationary in the axial direction and reliably impart a rotational force from the rear side, and the front inner cylinder (13) leaves the rear inner cylinder (13). The inner cylinder (12) advances with the screw rod (14) against the force applying device (16), and utilizes the buffering effect of the force applying device (16) to absorb impact to prevent the cosmetic material (M) from being pulled out or broken. This improves quality without compromising export functionality.

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 c...

[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.
