摘要： A clicking-type ball point pen has a so-called double-clicking mechanism in which a clicking rod is projected by depression and is retracted by further depression. At least one undercut is formed in the inner surface of a rear barrel cylinder or a component fixed to the rear barrel cylinder to prevent a rotor and the clicking rod from being removed forward from the barrel cylinder. The barrel cylinder incorporates a writing element having a large diameter. A point assembly holder at the distal end of the barrel cylinder has a straight portion, which constantly urges a writing ball forward with a load of 1 g to 80 g, and an elastic portion having spring properties integrally, or in a contact state if the straight portion and the elastic portion are separate components. An ink present from the interior of the point assembly to a follower is defoamed such that a gas, e.g., air, water vapor, or a gas formed of a vaporized organic solvent, which is larger than 0.524 mm.sup.3 (a volume of a sphere having a diameter of 1.0 mm) is absent therein.

摘要： A ball-point pen of the present invention is provided which includes: a ball-point pen refill being accommodated in the barrel cylinder and having: a tip with a tip ball held at the front end thereof; an ink reservoir which stores low-viscosity oily ink and has an ink follower provided in the rear end of the ink; and a joint disposed between the tip and the ink reservoir. The joint further includes: a valve chamber holding a ball valve in its inside and communicating with the rear end of the tip; and a ball valve seat disposed on the rear side of the valve chamber for the ball valve in order to prevent backward flow of ink. With this configuration, it is possible to provide a ball-point pen which, without need of any cap, can create dense writing traces free from blotting and unevenness even when a low viscosity oily ink is used.

摘要： A writing instrument cap having a clip as a separate part. The clip attachment, to which the clip is fitted, is projectively formed on the outer periphery of the cap. The clip attachment is formed with a vent hole penetrating between the interior and exterior of the cap and raised portions for attachment of the clip. The raised portions are provided on both sides of the vent hole, with respect to the circumference of the cap. When the clip is attached to the clip attachment, the clip covers the clip attachment and the vent hole and creates a clearance between the clip interior and the clip attachment so as to establish an air passage that communicates between the vent hole and the outside atmosphere.

摘要： In a writing instrument with a collector of the present invention, an ink absorber made up of a fabric sliver etc., capable of keeping ink therein is disposed inside the ink tank and is connected to the center core, longitudinal groove or the like as an ink feeder portion. The ink absorber is adapted to have a length at least reaching to a position more rearwards than the approximate center of the ink tank and has an outside diameter that is sized to be smaller than the inside diameter of the ink tank so as to create a space around itself for permitting free-state ink to move freely while the collector has a lead portion for establishing connection enabling ink to be led from the ink absorber to the air/liquid exchanger. Specifically, the lead portion of the collector may be configured of a projecting portion directly inserted into and connected with the ink absorber and a lead channel formed on the projecting portion. Alternatively, the lead portion may be formed, instead of being directly inserted to or connected with the ink absorber, by providing an ink lead channel capable of leading ink, which is connected to the center core, longitudinal groove or the like as an ink feeder portion that is connected to the ink absorber.

摘要： In a free-ink type collector writing instrument, the collector is formed with a partitioning portion for substantially shutting off the ink tank from the outside air, auxiliary retaining grooves are formed on the ink tank side with respect to the air/liquid exchanger of the partitioning portion while main retaining grooves are formed on the front side with respect to the air/liquid exchanger of the partitioning portion, a wide groove formed across the auxiliary retaining grooves for connecting the air/liquid exchanger and the ink tank is formed with a narrow groove extending from the air/liquid exchanger side to the ink tank side and lateral grooves capable of leading ink into the auxiliary retaining grooves. It is further effective if the capacity ‘ie’ of the auxiliary retaining grooves and the capacity ‘is’ of the main retaining grooves are designed so as to satisfy a relation ‘is>ie>0.05·is’ or if effective partitioning portion grooves are formed.
