  • Patent number: 11745920
    Abstract: 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.

  • Patent number: 11659913
    Abstract: 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.

  • Patent number: 10377167
    Abstract: A feeding pencil includes a body, a leading tube, a middle tube, a pipe member including drawing materials, a movable body, a holding member, and a sliding part. The drawing material moves forward in the leading tube when the pipe member engages with the leading tube in a rotating direction by moving the sliding part forward by a predetermined amount, when the leading tube and the body are rotated relatively in one direction while the pipe member is engaged with the leading tube in the rotating direction. The sliding part includes a stick-like part with a spring, and the stick-like part is inserted into an opening of a housing, and the sliding part is urged rearward by the spring when one end of the spring abuts the housing, and the other end of the spring abuts a face protruding radially outwardly from the stick-like part.

  • Patent number: 10239343
    Abstract: A feeding pencil includes a pipe member, a leading tube, a tubular main body, a movable body, and a holding member. The pipe member is disposed inside the leading tube and loads a drawing material. The movable body extends in an axial direction includes a male screw formed across an entire outer periphery thereof in the axial direction. The holding member holds the movable body. The pipe member includes a female screw on an inner surface thereof. The female screw screws with the male screw. A relative rotation between the leading tube and the main body relatively rotates the pipe member and the holding member and acts a screwing action between the male screw and the female screw. The screwing action moves the movable body forward to extrude the drawing material from the pipe member.

  • Patent number: 10076925
    Abstract: 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.
