BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a writing instrument such as a marking pen.

[0002]

2. Description of the Related Art Conventionally, a writing instrument of this type having a body having one open end (including a body whose other end is closed with a tail plug), a holder holding a pen core, and a cap, is capable of refilling ink. For this purpose, a screw is provided at the open end of the main body and is screwed and fixed to the holder. When refilling the ink, the holder is removed and the ink is refilled. At this time, the fitting between the holder and the main body was a screw fitting, and the airtightness between the holder and the main body was held by packing. But,
Repeated ink replenishment causes loss of packing, insecure fitting of the holder to the main unit, and repeated ink replenishment leaves traces of the initial pen core, leaving the pen in the same place. When the wick is arranged, the contact between the occluding body and the pen wick becomes uncertain, and the ink transmission becomes unstable. Also, in some writing implements, when refilling ink, the ink cartridge is fitted to the pen core of the writing implement, and the capillary action of the pen core causes the ink to be absorbed into the occlusion body. It takes time to refill. Further, the pen core is stained. When the balance between the pen core and the capillaries of the occlusion body is normally used, the ink is transmitted to the pen core by the pen core> the occlusion body. It becomes difficult to balance the capillary with the occlusion body.

[0003]

The problem to be solved by the invention is to maintain a constant contact between the pen core and the occlusion body from the beginning so that the ink transmission is also constant so that a pen core holder or the like can be used when refilling the ink. The present invention provides a writing implement which does not require ink replenishment by removing the writing implement. Further, the present invention solves the problem that ink can be replenished without removing the pen core holder or the like but takes time, and provides a writing implement that can easily and quickly replenish ink.

[0004]

Means for Solving the Problems A holder 4 holding a pen core 9 is fitted and fixed to the opening end 3 of the main body 1, one of which is an opening end 3, and covers the pen core 9 so as to cover the same.
In a writing instrument having a cap 10 which is detachably and airtightly fitted to the writing instrument, the holder 4 is composed of a pen core holding section 5, a fixing section 6, and an enclosure stopper shelf 8, and the pen core holding section 5 has a pen core 9 Is fixed, the fixing portion 6 is fitted with the main body 1, and a space S is provided between the pen core holding portion 5 and the fixing portion 6 so that ink can be replenished with the space S. It is a writing implement characterized by the following.

[0005]

With the ink supply, the ink flow is sucked from a replenishing bottle or the like by a spoid, and the ink is dropped from the spoid into the space S between the pen core holding section 5 and the fixing section 6.
Then, the dropped ink is applied to the space S formed by the outer wall of the pen core holding unit 5 and the inner wall of the fixing unit 6 or the rib 7.
, And falls on the occluder stopper shelf 8, and a part of the drops falls on the surface of the occluder 2 from the cut 13 and is absorbed by the occluder 2. Most of the ink in the occluder stopper shelf 8 is guided by the inclination of the occluder stopper shelf 8, falls into the center of the occluder 2, and is absorbed by the occluder 2.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1, FIG. 2, FIG. 3, FIG. Reference numeral 1 denotes a main body, one end of which is an open end 3, and the other end of which is a closed end. Here, the other end may be closed with a tail plug. Inside, an ink occluding body 2 impregnated with ink is arranged. The ink occluding body 2 is held by a squeezed opening of the main body. The material of the main body 1 can be selected from metal materials such as aluminum, and thermoplastic / thermosetting resins. Reference numeral 4 denotes a holder, which comprises a pen core holding part 5, a fixing part 6, and an occlusion stopper shelf 8, and the pen core holding part 5 and the fixing part 6 are connected by eight ribs 7. Here, the number of the ribs 7 is not particularly limited. The fixing portion 6 and the opening end 3 of the main body 1 are fitted and fixed, and cannot be detached. Further, a pen core 9 is fitted and fixed to the pen core holding portion 5 and is not removable. One end of the pen core 9 is in contact with the occlusion body 2 arranged on the main body 1. The occlusion body stopper shelf 8 has a funnel shape, and the occlusion body 2 side is converged. A notch 13 is provided in the occluder stopper shelf 8 below the rib 7 to divide the occluder stopper shelf 8 into eight. Here, the number of divisions of the storage body stopper shelf 8 in relation to the rib 7 does not matter. As the material of the holder 4, a thermoplastic or thermosetting resin can be selected. The space formed by the outer wall of the pen core holder 5 and the inner wall of the fixing part 6 or the rib 7 is S, and the distance T between the outer wall of the pen core holding part 5 and the inner wall of the fixing part 6 is 2 mm or more. is there. The space S is both an ink supply path and an air flow path.

Reference numeral 10 denotes a cap, which is fitted so as to cover the pen core 9 and the holder 4. An inner cap 11 is provided inside the cap 10, and is airtightly held between the pen core holding portion 5 and the open end of the inner cap 11. Furthermore, the inside of the cap 10 and the step 12 of the holder 4 is kept airtight. As the material of the cap 10, a thermoplastic or thermosetting resin can be selected. Next, as for the method of ink replenishment, ink is sucked from a replenishing bottle or the like with a spoid, and ink is dropped from the spoid into the space S of the pen core holding part 5 and the fixing part 6. Then, the dropped ink passes through the outer wall of the pen core holding unit 5 and the inner wall of the fixing unit 6 or the space S formed by the rib 7, and falls into the occluder stopper shelf 8, and a part of the ink is inserted from the cut 13. 2 and is absorbed by the occlusion body 2. Most of the ink in the occluder stopper shelf 8 is guided by the inclination of the occluder stopper shelf 8, falls into the center of the occluder 2, and is absorbed by the occluder 2. The storage body stopper shelf 8 also has the following effects. When the writing instrument is dropped with the cap 10 facing downward while the cap 10 is fitted, the occlusion body 2 jumps out toward the pen core 9, and the ejected occlusion body 2 is locked by the occlusion body stopper shelf 8, The air passage can also be secured by the cut 13. Therefore, the air flow path is not blocked by the fall, and the ink does not leak.

[0008]

[Effect] With the above configuration, the following effects can be obtained. Since the space S is formed by the outer wall of the pen core holding portion 5 and the inner wall or the rib 7 of the fixing portion 6, the main body 1 and the holder 4 are fitted and fixed, and the ink is replenished from the space S to the occluding body 2. it can. Since the holder 4 and the main body 1 are not removed each time ink is replenished, the airtightness of the main body 1 and the holder 4 can be always maintained, and the contact between the contact portion of the pen core 9 and the occlusion body 2 is not changed from the beginning. Since it is possible, the transfer of the ink can be surely performed. Due to the capillary relationship between the pen core 9 and the occlusion body 2, the ink can be directly dropped onto the occlusion body 2 instead of sucking up the ink from the pen core 9 to the occlusion body, so that the pen core is not stained and the time for ink replenishment is reduced. I can do it.
