  • Publication number: 20180154681
    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: 9788635
    Abstract: A rod-shaped cosmetic material feeding container in which a leading tube and a container main body are relatively rotated in one direction, an action of a screw part moves a rod-shaped cosmetic material supporting body to reach a movement limit, and then the leading tube and the container main body are further relatively rotated in the one direction. With movement of the rod-shaped cosmetic material supporting body stopped, while a spring portion in a rotation stopper tube shrinks, the screw part screws forward to release screwing of the screw part. Additionally, the movement of the rod-shaped cosmetic material supporting body is stopped and therefore the rod-shaped cosmetic material supporting body does not move back and forth in an axial direction. Accordingly, a rod-shaped cosmetic material does not move back and forth in the axial direction as well, thereby ensuring minimizing an impact to the rod-shaped cosmetic material.

  • Patent number: 9738113
    Abstract: A multi pencil includes a cylindrical main body, a cylindrical leading tube engaged with the main body, and a plurality of sliding parts that are each coupled with a plurality of drawing materials held in the interior of the leading tube and slidably provided by a constant distance with respect to the main body. Regarding this configuration, one arbitrary sliding part, out of the plurality of sliding parts, moves forward by a constant distance with respect to the main body, whereby the drawing material coupled with the sliding part is exposed from the leading tube, and in this state, the leading tube and the main body are relatively rotated in one direction, which allows the drawing material to move forward. In the multi pencil, the forward movement of the drawing material is regulated by the relative rotation of the leading tube and the main body in the one direction.

  • Publication number: 20170151826
    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.

  • Publication number: 20170151824
    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: 9532635
    Abstract: An applying material extruding container includes a leading tube and a pipe member inserted into the leading tube so as to be slidable in the axial line direction of the leading tube relative to the leading tube. In the initial state, the front end of the pipe member is located at a position displaced backward a predetermined distance from the front end of the leading tube, and the applying material is filled from in the pipe hole of the pipe member to in the tube hole of the leading tube. The inner surface of the region of the tube hole extends straight in the axial line direction. In the applying material extruding container, when the container main body and the control tube are relatively rotated in one/the other direction, by the screwing action of the first screw part, the pipe member is made to move forward/backward together with the applying material.
