A travelling section 30 for retaining the stick type cosmetic material is installed rotatably in an axial direction in an outer shell section 2 which is constituted by rotatably connecting a front cylinder 10 and a base cylinder 20. An outer circumferential surface 43 of a spiral cylinder 40 which is spirally engaged with a male screw section of the travelling section fits in a second slide surface provided on an inner circumferential surface of the base cylinder 20 which is one component of the outer shell section 2. Due to frictional force of this fit-in part, a cylindrical body and the spiral cylinder 40 are synchronously rotated. The travelling section 30 is engaged with an inner circumference of the front cylinder 10 and can slide only in an axial direction. When the travelling section 30 reaches the uppermost limit or the lowermost limit by relative rotations of the front cylinder 10 and the base cylinder 20, if further rotary torque is furnished, synchronously rotating means are released and the base cylinder 20 and the spiral cylinder 40 are raced.

1. A container for a stick type cosmetic material having a mechanism for feeding the stick type cosmetic material, said container comprising:a front cylinder; a base cylinder which can be connected with the front cylinder; an outer shell section which is constituted by coaxially and rotatably connecting the front cylinder and the base cylinder; a travelling section installed in the outer shell section, the travelling section having a retaining section for retaining the stick type cosmetic material and travelling in an axial direction in the outer shell section; a rotation regulating mechanism which allows the travelling section only to relatively slide in an axial direction with respect to one of the front cylinder and the base cylinder which constitute the outer shell section; a spiral cylinder which has a female screw section to be spirally engaged with a male screw section installed at the travelling section; a spiral engagement mechanism which is constituted by spiral engagement of the male screw section and the female screw section; synchronously rotating means for rotating, by slide resistance, the spiral cylinder synchronously with the other one of the front cylinder and the base cylinder which constitute the outer shell section; and travel regulating means for regulating travel of the travelling section at its travelling limit in the outer shell section, wherein when the front cylinder and the base cylinder are relatively rotated, the travelling section is fed out by the feeding mechanism, and when rotary torque which causes the front cylinder and the base cylinder to relatively rotate when the travelling section reaches an uppermost limit exceeds a value of the slide resistance of the synchronously rotating means, the synchronously rotating means are released and the spiral cylinder and the male screw section are synchronously rotated.
