Title:
LIPSTICK CONTAINER PROVIDED WITH PUSH-BACK PREVENTING MEANS
Document Type and Number:
Japanese Patent JP3308188
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent a lipstick from moving down when downward force in axial center direction is applied to the cosmetic material by originally forming the surface section of terminal part of a projection extended from a cosmetic material holding cylinder to the outside in radial direction.
SOLUTION: A terminal part 58 of a projection 24 facing the outside in the radial direction has the chimfered surface section. The terminal part 58 has a complex surface having a 1st surface section 60 facing the outside in the radial direction and a 2nd surface section 62 facing the outside in the radial direction. The 1st surface section 60 is arranged in almost parallel to a lengthwise axial center 32 of the cosmetic container and faces the outside in the radial direction toward a bottom face wall 48 of a helical groove 42. The 2nd surface section 62 is arranged so as to form the acute angle with the lengthwise axial center 32 of the cosmetic container. Therefore, when downward force in the axial center direction is applied to the cosmetic material, a wedge effect is exerted upon the inner surface section of an intermediate sleeve 40 adjacent to a downside wall section 46 of the helical groove 42, and push-back is prevented. Accordingly, the projection 24 prevents push-back in cooperation with the tube-shaped intermediate sleeve 40.
