摘要： Proposed is multi-color marker pen which is composed of a cap (200) and a casing (100) covered by the cap (200). The casing (100) is composed of a linear shaft (110) covered by the cap (200) and having the shape of a hollow body, a sealing part (120) coupled to the upper part of the linear shaft (110) and having a guide (121) formed therein, and a button operation part (130) coupled to the upper part of the sealing part (120). A plurality of tubes (300) is provided in the casing (100), and the upper part of each of the plurality of tubes 300 is coupled to the sealing part (120) in which the guide (121) is formed. The button operation part is composed of three buttons, and by pressing the button operation part (130), the lower part of each of the tubes is ejected through a hole (111) formed in the lower end of the linear shaft (110). In addition, the casing (100) the linear shaft (110) covered by the cap (200) and having the shape of a hollow body, the sealing part (120) coupled to the upper part of the linear shaft (110) and having the guide (121) formed therein, and an operation handle (130) coupled rotatably to the upper part of the sealing part (120). The plurality of tubes (300) is provided in the casing (100), and the upper part of each of the plurality of tubes 300 is coupled to the sealing part (120) in which the guide (121) is formed, and due to the rotation of the operation handle (130), the lower part of each of the tubes is ejected through the hole (111) formed in the lower end of the linear shaft (110). Molten synthetic resin is injected into a mold (1000) composed of an upper mold (1100) and a lower mold (1200) so as to manufacture the casing, the cap, and the operation handle.

摘要： 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.

摘要： The present invention relates to a multifunction pen. It integrates the function of a pen, a mechanical pencil, and a highlighter into a single pen body. A user can use it as a pen, a mechanical pencil, or a highlighter as he or she wishes by simply sliding function buttons near one end of the pen body. The unique seal structure of the present invention prevents the highlighter from drying out when the multifunction pen is not in use, which prolongs the lifespan of the highlighter.
