【発明の詳細な説明】
本発明はボールペン、繊維ペン（通称、サイン
ペン）の筆記具において特に水性インキを使用す
る筆記具の書記部のインキ乾燥防止に関する改良
である。DETAILED DESCRIPTION OF THE INVENTION The present invention is an improvement in writing instruments such as ballpoint pens and fiber pens (commonly known as felt-tip pens), particularly regarding prevention of ink drying in the writing section of writing instruments that use water-based ink.
近時油性インキに代えて水性インキが書き易

難いため使用されるに至つた。この水性インキは

を防止せんとするにある。 Recently, water-based inks have come into use in place of oil-based inks because they are easier to write on, dry quickly, and are less likely to get stained by touching other objects. This water-based ink dries easily in the writing area compared to oil-based ink, and many proposals have been made to prevent this from drying out, but simply sealing only the writing area does not provide a sufficient effect. The purpose cannot be fully achieved unless consideration is given to the ventilation holes made in the cartridge type writing font. An object of the present invention is to prevent the ink from drying by blocking communication between the ventilation holes and the outside air as well as the writing section.

A large diameter hole 5 is formed above the lower end surface 2a, and a cylindrical closing member 7, which will be described later, is fitted into the large diameter hole 5. 2 has an annular protruding edge 2b formed from the lower end, a thread 2c carved into the lower outer periphery and screwed onto the shaft cylinder 1 so as to be removable, and an annular recessed portion 14 on the upper surface of the annular protruding edge 2b. The annular protruding edge 13 provided on the inner circumferential surface of the lower end of the cap 12 is fitted into this to tightly fit the cap 12 to the neck 2. Of course, it is also possible to have a structure that tightly fits onto the outer periphery of 1.

する。 Next, 7 is a cylindrical closing member, that is, packing, which is made of an elastic material such as rubber or synthetic resin and has a cylindrical cross section 9, and the cartridge type writing body 3 is tightly inserted into the central hole. An annular flange 8 is provided at the lower end of the outer periphery of the closing member 7, leaving a short cylindrical portion 7a at the lower end, and a cylindrical portion 9 above the annular flange 8 is tightly fitted into the large diameter hole 5 of the neck portion 2. It fits into the
The annular flange 8 of this cylindrical closing member 7 is in close contact with the rear end surface 2a of the neck portion 2, and the cartridge type writing body 3 has the short cylindrical portion 7a somewhat expanded at the tapered shoulder portion 16 between it and the small diameter cylindrical portion 3b. Since it is adhered in an open manner, the cylindrical closing member 7 can completely hermetically block the flow of air between the center hole 6 of the neck portion 2 and the inside 1a of the shaft cylinder 1.
As another embodiment in which the cylindrical closing member 7 blocks the flow of air between the center hole 6 of the neck portion 2 and the interior 1a of the shaft tube 1, as shown in FIG. An annular ring 10 protruding inward is provided on the inner periphery of the cylindrical portion 9, and this annular ring 10 is bonded to the outer diameter of the small diameter cylindrical portion 3b of the cartridge type writing body 3 even if there is a large/small diameter difference. Similarly to the above, ventilation between the center hole 6 of the neck portion 2 and the interior 1a of the shaft cylinder 1 is blocked. 11 is a coil spring cartridge type writing font 3
This is because it is easy to remove when replacing the cartridge type writing body 3 by attaching it between the shoulder of the small diameter cylindrical part 3b and the center hole of the neck part 2. This is used when there is no difference between the outer diameter of the cylindrical portion 3b and the hole diameter of the cylindrical closing member 7, and they are firmly inserted.

ある。 Next, reference numeral 12 denotes a cap of the writing instrument, and an annular protruding edge 13 is provided on the inner periphery of the opening, which is fitted into an annular recess 14 provided along the upper surface of the brim-like protruding edge 2b of the neck portion 2, and the cap 12 is tightly attached. In one embodiment, it is not limited to this, but it may be tightly fitted to the outer periphery of the shaft cylinder 1. Reference numeral 15 denotes a closing member made of rubber or synthetic resin provided on the canopy of the cap, which protrudes inside the cap, and in the case of a ballpoint pen, its tip end is brought into contact with the tip end surface of the neck portion 2 to enclose the writing portion 3a, and the cap 1 is closed.
2. The communication between the inside of the cartridge-type writing body 3 and the outside air communication hole opened in the end of the cartridge-type writing body 3 or the small-diameter cylindrical portion 3b is cut off. Furthermore, when the writing part 3a of the cartridge type writing body 3 is a felt-tip pen made of fiber, a recessed hole part 15a is provided inside from the lower end surface of the closing member 15 for protecting the writing part 3a, and the writing part 3
When the cartridge-type writing body 3 is in a retractable structure, the distal end surface of the closing member 15 comes into close contact with the distal end surface of the neck portion 2 to block air circulation. The cartridge-type writing body 3 has an ink storage material placed inside it except for the small-diameter cylindrical portion 3b, which absorbs the ink, and a ventilation hole is opened at the end. In this invention, a ventilation hole is opened in the small-diameter cylindrical part 3b, so that the cylindrical body 9 can block communication with the outside air and prevent the ink inside the cartridge-type writing body from drying together with the writing part 3a. Ink can be dried more effectively. There is also the advantage that the location to be opened in the small diameter cylindrical portion 3b can be arbitrarily selected. It is clear that the present invention can also be used in the same manner for other writing instruments having writing parts that are susceptible to drying.

のである。 Since the present invention is constructed as described above, a cartridge-type writing body such as a ballpoint pen, a fiber pen (commonly known as a felt-tip pen), which is installed in the barrel, has a large diameter hole formed at the lower end of the neck, that is, on the barrel side. The annular flange of the closing member is in close contact with the lower end of the neck, and the shoulder of the cartridge writing body is in close contact with the short cylindrical portion of the cylindrical closing member to close the lower part of the center hole of the neck, thereby connecting the center hole and the shaft tube. The outside air inside the cap is shut off, and the tip of the neck comes into contact with an elastic closing member attached to the cap to seal the writing section, and both of these block the entire center hole including the writing section from communicating with the outside air. Therefore, it is possible to open a ventilation hole at any location in the small-diameter cylindrical portion of the cartridge-type writing body, and it is also possible to prevent the writing portion from drying out.
