Patent number: 11745920Abstract: An application container includes a main body that holds an application material, a cap, and a weakened portion that connects the cap to an outer peripheral surface of the main body. The main body has a tubular shape that extends in an axial direction and forms an opening to expose the application material. The cap overlaps the opening of the main body in the axial direction. The weakened portion is oriented substantially in a circumferential direction of the main body, at a position that is located away from the opening in the axial direction of the main body, and is configured to be split in response to an external force, so as to separate the cap from the main body.Type: GrantFiled: August 20, 2021Date of Patent: September 5, 2023Inventor: Yoshikazu Tani

Patent number: 11659913Abstract: An application container includes a leading cylinder that internally contains an application material, and has an opening through which the application material is exposed. The opening extends in a major axis direction, and has a minor axis direction. The leading cylinder has a front edge curved to bulge to an outside of the leading cylinder from a tip located on one side in the major axis direction toward the other side. When viewed from the other side, the opening extends rearward from the tip in a slit shape. A first application material holder located on both sides of the opening in the minor axis direction is formed in a tip portion of the leading cylinder having an outer surface extending rearward while being curved to bulge to the outside of the leading cylinder from the tip.Type: GrantFiled: March 11, 2021Date of Patent: May 30, 2023Inventor: Yoshikazu Tani

Patent number: 10076925Abstract: A feeding pencil includes a main body, a leading tube, a middle tube, and a ratchet mechanism. The middle tube is engaged to the leading tube to be relatively rotatable. A relative rotation between the leading tube and the main body in one direction moves a drawing material forward. The ratchet mechanism allows the relative rotation between the leading tube and the main body in the one direction, and regulates the relative rotation in another direction. The ratchet mechanism includes an elastic projecting part and a concave-convex part. The concave-convex part engages with the elastic projecting part to be movable in an axial direction and rotatable. A protrusion disposed at a center tube removably engages with an annular convex part disposed at an outer surface of the leading tube in the axial direction.Type: GrantFiled: November 17, 2016Date of Patent: September 18, 2018Assignee: TOKIWA CORPORATIONInventor: Yoshikazu Tani
