DIRECT INK STORING TYPE WRITING INSTRUMENT |
摘要 |
A longitudinal groove which allows a number of annular grooves formed on the outer peripheral surface of an ink storage body to communicate with an ink chamber is cut halfway into the thickness of a flange formed at the rear part of the ink storage body. An outer part of the longitudinal groove cut into the flange is made to communicate with a passage which is defined by a cutout formed on the periphery of the flange and the inner wall of the barrel cylinder so that this passage establishes communication between the longitudinal groove and the ink chamber.
