本考案は、ペン体交換式の水性マーキングペン
に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a water-based marking pen with an exchangeable pen body.
水性マーキングペンは、プラスチツクや繊維体

は、ペン体と中綿との接触が確実に行われている
ことが重要である。
Water-based marking pens have a pen body made of plastic or fiber molded into a rod shape, which is fixed to the opening at the tip of the tip fitted into the barrel, with the tip of the pen protruding from the tip, and the rear end of the pen body. The pen is inserted into a padding that absorbs ink, and the water-based ink is transferred to the tip of the pen body for writing. In order to ensure that the ink flows smoothly and that the ink does not run out, it is important that the pen body and the filling are in reliable contact.
ところで、このペン体は摩耗しやすいために筆
記具としての寿命が短い欠点がある。また、筆跡
の太さはペン体の外径によつて定まるため、筆跡

である。 By the way, this pen body has the drawback of being easily worn out and thus having a short lifespan as a writing instrument. In addition, the thickness of handwriting is determined by the outer diameter of the pen body, so in order to write with a wide variety of handwriting thicknesses, prepare multiple water-based marking pens with different thicknesses of pen bodies. There is a need. For this reason, if the pen body is made replaceable, the life of the writing instrument will be extended, or one water-based marking pen can serve as multiple water-based marking pens, which is convenient.
しかしながら、ペン体を交換するときに、新し

は前回のペン体の挿入跡の孔が既に明いており、
この孔と同等か、より細いペン体を挿入すると、
この孔の内面がペン体に密着しないためである。 However, when replacing the pen body, the rear end of the new pen body is inserted into the batting which is an ink absorbing body, but at this time the contact between the two is incomplete.
There is a problem that the ink is not sufficiently transferred to the pen body and the ink runs out when writing. This is because this filling is made of ultra-fine fibers arranged into a rod shape, so it has almost no elasticity, but there are already holes in the filling from where the pen body was inserted the previous time.
If you insert a pen body that is equal to or thinner than this hole,
This is because the inner surface of this hole does not come into close contact with the pen body.
そこで本考案は、ペン体交換時のペン体とイン

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an interchangeable marking pen in which the pen body and the ink storage body are securely contacted when the pen body is replaced, and the ink does not run out.
本考案の構成は、棒状ペン体が固着された先口

The structure of the present invention is a pen body exchangeable marking pen in which the tip to which the rod-shaped pen body is fixed is removably fitted into the tip opening of the barrel, and the pen body can be replaced together with the tip. It is characterized in that the rear end is removably inserted into a slit formed in an elastic foam having open cells that is in contact with a batting that occludes water-based ink.

ない。 In other words, the rear end of the pen body is inserted into a slit formed in the elastic foam with open cells that is in contact with the filling, so when the pen body is removed to replace the pen body, the elastic foam The incision on the body where the pen was inserted becomes obstructed. Therefore, when a new pen body is inserted into this cutout, the pen body is wrapped in the elastic foam and makes sure contact. Therefore, ink flow is ensured and no ink runs out.

ようになつている。 In FIG. 1, a filling 2 and an elastic foam 5 are housed in a barrel 1, and the front end surface of the elastic foam 5 is in contact with a plurality of ribs 11 formed inside the tip of the barrel 1. There is. The batting 2 is made of crimped ultrafine fibers such as polystyrene and formed into a rod shape, and has a large capacity to absorb water-based ink.The elastic foam 5 is made of open cells like expanded polystyrene. It is highly elastic. The filling 2 and the elastic foam 5 are in contact with each other at their end surfaces, and the water-based ink occluded in the filling 2 is transferred to the elastic foam 5. A tip 3 is removably fitted into the opening at the tip of the shaft cylinder 1, and a cylindrical portion 31 is integrally connected to the rear of the tip 3. The pen body 4 is made of plastic or fibrous material molded into a rod shape, and the rear end of the cylindrical portion 31 is caulked inward to secure the pen body 4. The rear end of the pen body 4 is inserted into an elastic foam body 5, and the water-based ink in the batting 2 is transmitted to the tip of the pen body 4 via the elastic foam body 5 and used for writing. Here, a cut 51 is provided at the center of the elastic foam 5.
is formed so that the pen body 4 can be easily inserted and removed.

い筆記具となる。 Therefore, when replacing the pen body 4 in the interchangeable marking pen having such a configuration, the tip 3 is removed from the barrel 1 and the tip 3 to which the new pen body 4 is fixed is inserted at the tip of the barrel 1. Fits into the opening. At this time, the rear end of the pen body 4 is inserted again into the cut 51 of the elastic foam 5, but since this cut 51 is closed, the pen body 4 is wrapped in the elastic foam 5. Make sure to make contact. Therefore, the ink is reliably transferred from the elastic foam body 5 to the pen body 4, the ink comes out reliably, and the writing instrument does not run out of ink.
