Patent number: 9877565Abstract: 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.Type: GrantFiled: October 28, 2016Date of Patent: January 30, 2018Assignee: TOKIWA CORPORATIONInventor: Arata Sasaki

Patent number: 9237792Abstract: 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.Type: GrantFiled: August 27, 2014Date of Patent: January 19, 2016Assignee: TOKIWA CORPORATIONInventor: Arata Sasaki

Patent number: 7908749Abstract: 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.Type: GrantFiled: July 11, 2007Date of Patent: March 22, 2011Assignee: Tokiwa CorporationInventor: Arata Sasaki
