摘要： A push-button type writing instrument makes use of a replaceable pen unit (2) having a reservoir (5) for an evaporative ink and a writing part (6). To prevent evaporation when the pen is not in use, the forward end of the pen unit is received within a flexible sealing member (12) contained within a lead chuck (13). When the pen unit is retracted, the forward end is sealed within the sealing member, the mouth of which is held closed by the chuck. When the pen unit is projected forwardly the chuck (13) also advances and it is opened, thereby allowing the mouth of the sealing member (12) to open and permit the forward end of the pen unit to project from the barrel (1) into the writing position.
