Whiteboard-marker having arch-shaped housing

摘要

A whiteboard marker having an arch-shaped housing is disclosed. The whiteboard marker of the present invention includes an ink tube (11a, 11b), a housing (13), in which the ink tube is housed, a front cap (17a, 17b), which is coupled to the housing, a penpoint (15a, 15b), which is fastened to the front cap, and a lid (19a, 19b). The present invention is characterized in that the housing is formed to have an arch shape, so that ink flows towards penpoints due to osmotic pressure and to gravity. Furthermore, the whiteboard marker may comprise first and second marker units. Each of the first and second marker units includes a front cap, which has a penpoint and is coupled to each of opposite ends of the arch-shaped housing, an ink tube, which is housed in the housing such that it contacts the penpoint, and a lid, which covers the front cap. The present invention allows a user to alternately use the whiteboard marker in opposite directions and is advantageous in that ink, which is contained in the ink tube, can be completely used.
