Patent ID: 6899484

Claim:
A stick type cosmetic material feeding container, comprising: a core chuck member adapted to retain a stick type cosmetic material; a front cylinder; and a base body rotatably connected with the front cylinder; wherein due to relative rotations of the front cylinder and the base body, the stick type cosmetic material retained by the core chuck member slides forward and backward along a through hole extending in an axial direction in the front cylinder; wherein a plurality of first slide grooves are formed along an inner circumference of the front cylinder and along the through hole, the through hole having an inside diameter which is almost equal to an outside diameter of the stick type cosmetic material, the first slide grooves extending in the axial direction; wherein a plurality of second slide grooves are located at ends of the first slide grooves, formed continuously from the ends, formed deeper than the first slide grooves, and are disposed to correspond to a position of the core chuck member when the core chuck member is in a maximum retracted position; wherein a plurality of claws are formed at a front end section of the core chuck member so as to retain the stick type cosmetic material and are slidably guided by the first slide grooves and the second slide grooves, back surfaces of the claws slide and come into contact with bottoms of the first slide grooves, and inner surfaces of the claws almost coincide with the inside diameter of the through hole when the claws are disposed in the first slide grooves, and wherein when the claws are disposed in the second slides grooves, the claws will elastically deform outward toward an outer circumference of the front cylinder so that the inner surfaces of the claws will be disposed to form an opening that is larger than the inside diameter of the through hole, so that when the stick type cosmetic material is loaded in the core chuck member and the claws are located at the second slide grooves, the stick type cosmetic material may be received in the opening and inside the claws, and when the claws are located at the first slide grooves, the opening is made smaller and the claws retain the stick type cosmetic material by tightly sandwiching the stick type cosmetic material with pressure on an outer circumference side of the stick type cosmetic material.
