In addition, in a conventional line marker, etc., the ink was built into the applicator in a state of being impregnated with the batting arranged in the liquid storing section, but in recent years, it has fluidity in order to store a larger amount of ink. In many cases, a configuration called a free ink type in which the ink is directly incorporated in the state as it is is adopted.

FIG. 11 is a sectional view of a conventional free ink type applicator. FIG. 12 is an enlarged sectional view of a tip portion of the applicator of FIG. The free ink type applicator 200 includes a main body 201, a pen point member 202, and a valve member 20.
3. It is composed of a slide stopper 205 and a tail stopper 206. The pen point member 202 further includes a pen point tip (coating member) 210 and a slide holder 211.

When using the conventional applicator 200, the pen tip 210 is pressed against paper or the like. At this time, the slide holder 211 of the pen tip 210 moves backward toward the liquid storage section 212 of the main body 201, and the slide holder 211 presses the central portion of the valve member 203. Then, the center of the valve member 203 is deformed so as to protrude toward the liquid storage part 212 side, the volume of the liquid storage part 212 is reduced, and the pressure in the liquid storage part 212 increases. At the same time, the valve member 203 is elastically deformed so that the inner peripheral surface is separated from the through hole 215, and the liquid storage part 212 and the pen tip 210 communicate with each other. As a result, the ink in the liquid storage 212 is supplied to the pen tip 210 via the through hole 215.

After the writing and application are completed, the pen tip 210
Is separated from the paper surface, the valve member 203 advances the slide holder 211 by its own repulsive elastic force, and returns to the original closed posture. When the slide holder 211 returns, the through hole 215 is closed again, and the supply of the ink in the liquid storage 212 is cut off. Further, with the advance of the slide holder 211, the inside of the liquid storage part 212 is depressurized, so that the slide stopper 205 is pushed by the atmospheric pressure and advances at the same time.

In the applicator 40 of this embodiment, when the pen point member 11 is pressed against paper or the like, the flange portion 45 is compressed and shrunk. As a result, as in the previous embodiment, the ink reservoir 10 and the total volume from the ink reservoir 10 to the pen tip 21 decrease, the pressure of the ink rises, and the ink flows into the pen tip 21.

In the applicators 1 and 40 of the two embodiments described above, the pen tip 21
In the ink flow path between the two, there is no member that hinders the flow of ink. However, depending on the properties such as the viscosity of the ink, it may be preferable to provide a flow rate restricting member such as a valve.

On the other hand, when the pen tip 21 is pressed against paper or the like, the elastic member 61 is compressed and contracted, the total volume reaching the pen tip 21 decreases, and the pressure of the ink increases. Further, when the holder 65 moves toward the ink storage unit 10, the small-diameter portion 66 of the holder 65 separates the partition 62.
To expand the gap of the slit 63. as a result,
The ink flows out of the ink reservoir 10. When the pen tip 21 is separated from paper or the like, the slit 63 is closed by the elastic force of the elastic member 61, and the outflow of ink is blocked.

In the applicator 60 of this embodiment, the slit 6
3 so that the holder 3 can be pushed open efficiently.
The small diameter portion 66 is provided at the rear end of the small diameter portion 66.
Is optional. Coating device 70 shown in FIG.
Shows an example in which the holder does not have a small diameter portion.
