  • Patent number: 11510479
    Abstract: A rod-shaped cosmetic material feeding container includes a sleeve that is capable of accommodating a rod-shaped cosmetic material, a barrel that is engaged with the sleeve so as to be rotatable relative to the sleeve, a screw that is disposed inside the barrel so as to be synchronously rotatable, and a mechanism portion that is accommodated inside the sleeve and the barrel and configured to feed out the rod-shaped cosmetic material. The screw includes a slope and a female screw. The mechanism portion includes a lead holder, an ejection rod, and a propelling rod. The sleeve has an advancing limit reached by the lead holder of the mechanism portion fed out by a screwing action of the female screw and a male screw when the sleeve and the barrel are rotated relative to each other.

  • Patent number: 10506864
    Abstract: A stick-shaped cosmetic material appears or disappears from a front end of the tip cylinder along with the advance or retract of the moving body, a concave portion extends to a holding portion on an inner peripheral surface of the tip cylinder, a convex portion held by the concave portion is formed on an outer peripheral surface of the stick-shaped cosmetic material, the shape of the stick-shaped cosmetic material when viewed from the front side is formed so as to be tapered as being separated from an opposing portion to the holding portion, and a width of the opposing portion of the stick-shaped cosmetic material when viewed from the front side is substantially the same as a width of the holding portion when viewed from the front side.

  • Patent number: 9877565
    Abstract: When a lid storing an impregnation body impregnated with a liquid cosmetic material is attached to a container body holding a thick applicator at a front end thereof, a slope of a front end face of the thick applicator is stuck into the impregnation body to thereby easily intrude thereinto. Accordingly, an appropriate amount of the liquid cosmetic material impregnated into the impregnation body can be held and a thick line can be drawn by the thick applicator storing the liquid cosmetic material. In this way, since the liquid cosmetic material is stored in the lid while being impregnated with the impregnation body, the liquid cosmetic material does not leak from the lid even in a posture in which the lid separated from the container body is disposed, for example, laterally or reversely.

  • Patent number: 9237792
    Abstract: When a turning portion on the front end side of the cover is turned in one direction, a turning-portion engagement part disposed in the turning portion engages with a container main body-side engagement part so as to close the cover. When the turning portion of the cover is turned in the opposite direction, engagement between the turning-portion engagement part and the container main body-side engagement part is released. When the turning portion is kept turned in the opposite direction, a turning-portion opening-operation auxiliary portion disposed in the turning portion abuts on a container main body-side opening-operation auxiliary portion and the cover can be pressed up with a weak force by the principle of the lever.

  • Patent number: 8821059
    Abstract: To make a cosmetic container convenient, a closing part 6b of a discharge cylinder 6 closes an insertion hole 2h of a middle cylinder part 2 and seals a cosmetic A when a moving part 3 is positioned at a first stopping position, the discharge cylinder 6 protrudes by a predetermined length from an end face of the insertion hole 2h and slits 6c of the discharge cylinder 6 are exposed when the moving part 3 is moved from the first stopping position to a second stopping position separating in an axial direction, so that a user can visually confirm that the cosmetic can flow out through the slits 6c, the discharge cylinder and a discharge cylinder opening part 6a, and the moving part 3 is left at the second stopping position, so that the cosmetic A can securely flow out without variation when in use.

  • Patent number: 7908749
    Abstract: A sharpener for a stick-shaped cosmetic material comprises guide rails (3h) disposed in a longitudinal direction over a sliding surface (3d), and a continuous surface (3g) at an upper side of both surfaces. The sliding surface (3d) is formed in an acute inner angle shape as seen in the longitudinal direction for sliding a leading end portion of the cosmetic material thereon. The continuous surface (3g) constitutes an upper side of a blade with a cutting edge (3e) facing to a rear end edge of the sliding surface (3d) at a position slightly higher than the sliding surface (3d). A leading end portion of a stick-shaped cosmetic material feeding container (100) is guided by the guide rails (3h), thereby preventing the container (100) from being shaken.
