Abstract
A cartridge type stick-shaped cosmetic material feeding container 1 comprises a cartridge 2 and a container body 3, and the cartridge 2 rotatably connects a base cylinder 20 and a front cylinder 10 having an opening hole 11 through which a stick-shaped cosmetic material A advances and retreats. The stick-shaped cosmetic material A is retained by claws 32 at a front end of a core chuck member 30 inserted and an O-ring 4 is wound to an outer circumference of the base cylinder 20. Due to a feeding mechanism in the cartridge 2, the stick-shaped cosmetic material A retained by the core chuck member 30 advances and retreats along the front cylinder 10 with rotations of the front cylinder 10 and the base cylinder 20. The feeding mechanism of the cartridge 2 inserted in the container body 3 functions when the base cylinder 20 and the container body 3 synchronously rotate by frictional resistance of an inner circumference of the container body and the O-ring 4 wound to the base cylinder 20. Further, when a rotary load greater than frictional resistance of the O-ring 4 is applied at the feeding limit, the cartridge 2 and the container body 3 begin to make relative rotations so that no further overload greater than the rotary load is applied to the feeding mechanism.
