- the applicator of this embodiment has sufficient elasticity to prevent dripping over time in the ink storage tube and remaining on the wall surface due to ink consumption, and to prevent backflow that is not easily deformed by impact. It has a body.
- fine particle silica was further added, and in the same manner as in the above example except for the composition shown in Table 3, a backflow prevention member was adjusted to prepare a correction ballpoint pen, and the pen point was directed upward.
- the storage stability of the ink, the ability of the backflow preventer to follow the oil-based ink when writing on paper, and the show-off during storage were evaluated.
- Sagging is a phenomenon in which the backflow preventing body is deformed over time, and is evaluated in terms of storage stability with the pen tip facing upward in the same manner as in the above-described embodiment.
- the release ability was evaluated as X when the backflow preventing physical strength base material exudes over time, and as ⁇ when the exudate did not exude. Table 3 shows the results.

- a gelling agent aluminum 2-ethylhexanoate.
- the ink containing tube was filled with the oil-based ink containing the ink, and then, a dichryserine ethylene oxide adduct (trade name “SC-E2000” manufactured by Sakamoto Yakuhin Co., Ltd.) was used as a base material on the oil-based ink.
- Polyacrylic acid containing 98.5% by weight with respect to the total amount of the backflow preventive and having a molecular weight of 1,000,000,000 or more (manufactured by BF Goodrich Co., Ltd., trade name "Carbopol 940") is 0% based on the total amount of the backflow preventive. . Filled with a backflow preventive containing 1-3% by weight.
- oil-based ink such as a correction liquid is used to prevent the backflow prevention body from penetrating into the ink.
- the ink does not adhere to the ink and continuously exhibits self-tally jungling properties. Further, since the ink container is a transparent ink container, the remaining amount can be clearly checked. Further, if the applicator is an applicator using an ink storage tube treated with a coating aqueous solution containing an ionic fluorine-based surfactant and a modified polybutyl alcohol whose ionicity is opposite to that of the surfactant, a temperature of 50 ° C.
- ⁇ initial '' indicates the time when the ink was first applied to the paper at the time of assembling the ball-point pen
- ⁇ storing for three days '' means ⁇ three days after assembling the ball-point pen. Indicates the self-cleaning state when applied to the paper surface.
- the applicator of the present invention can be used for a correction tool such as a correction pen and other applicators.
