WIPO Patent Application WO/2019/022372
Kind Code:

Abstract:
The present invention relates to a three-color marker pen. More particularly, the present invention relates to a three-color marker pen comprising a cap (200) and a case (100) covered by the cap (200). The case (100) comprises: a line shaft (110) having the shape of a hollow body, which is covered by the cap (200); a sealing portion (120) which is coupled to the upper portion of the line shaft, and which has a guide (121) formed thereon; and an operation handle (130) rotatably coupled to the upper portion of the sealing portion (120). Multiple cores (300) are contained in the case (100). The upper portions of the multiple cores (300) are coupled to the sealing portion (120), on which the guide (121) is formed, such that the lower portions of the cores (300) are drawn out by a rotation of the operation handle (130) through holes (111) formed in the lower end of the line shaft (110), respectively. The three-color marker pen according to the present invention has a noticeable advantage in that respective cores pass inside the guide and are drawn out through the holes formed in the lower end of the line shaft, respectively, and the lower end of the line shaft is formed along a streamlined curved line from the upper portion toward the lower portion thereof such that, when a core descends, the outer peripheral edge of a nib holding portion slides downward while contacting the inner wall of the line shaft, thereby protecting the nib of the core from damage.
