The main moving body 5 rotates in the opposite direction to the above due to the screw groove 6, but since the ratchet teeth 8 and the ratchet teeth 19 are spaced apart, the passive body 16 will not rotate, and in the event that they are not spaced apart, Due to the shape of the clutch teeth, the teeth will not escape and rotation will not be transmitted. If the push button 10 is pressed again and the release operation is performed, the above operation is repeated, and the passive body 16 is rotated only when the push button 10 is pressed, and accordingly the piston 28
Since the cosmetic A is leached into the tip of the brush by moving the brush forward, an appropriate amount of the cosmetic A can be applied to the tip of the brush by clicking the push button 10 an appropriate number of times. Furthermore, when the cosmetic A in the cartridge body 21 runs out, or when you want to replace it with another cosmetic while in use, the locking tube 25 and the fixed tube 27 can be easily separated by pulling out the cartridge body 21. Instead, by inserting a new cartridge body 21 into the outer tube 1 and connecting the rotation prevention tube 25 and the fixed tube 27, the cartridge can be used again.
