To provide a clicking type writing instrument capable of reliably suppressing volatilization of ink from the pen tip at least before the start of use. The clicking type writing instrument A has a refill 20 provided in a barrel cylinder 10; a pen tip 30 configured to discharge ink from an ink storage member 18 accommodated in the refill 20 by capillary action and to be allowed to be projected from and retracted into a front end of the barrel cylinder 10 by means of a clicking mechanism 70 provided in the barrel cylinder 10; and at least a seal member 40, arranged around an outer periphery of the pen tip 30 near a front end side of the pen tip, and formed with a through-hole 42 in a center of the seal member, through which the pen tip 30 can slidably move back and forth when the pen tip 30 is housed inside the barrel cylinder 10.

To prevent ink from dripping, drying, and the like.

A writing utensil includes: a shaft tube; a writing chip that protrudes more toward the front than the shaft tube so as to discharge ink when pressed against a written face; and an ink supply part that supplies ink to the writing chip from a rear side, wherein the writing chip is at a separate position that is separated toward the front across a space with respect to the ink supply part and is moved due to a predetermined operation to a contact position where the writing chip comes into contact with the ink supply part from a front side.

A refill for a writing felt pen, the refill comprising a deformable pouch and a nib inserted into the deformable pouch, the deformable pouch comprising a mix of dry absorbent polymer, fibers and dry ink.

An application container (1) includes a container main body (2); an inner plug member (20); and an impregnation material (30). The inner plug member (20) includes an impregnation material accommodating portion (21), and a valve body accommodating portion (22) which includes a valve seat (22a) on an impregnation material accommodating portion (21) side and a valve body support portion (22b) on a container main body (2) side and in which a valve body (22c) is disposed so as to be movable between the valve seat (22a) and the valve body support portion (22b). A communication groove (50) which forms a gap between the valve body (22c) and the valve body accommodating portion (22) in a state where the valve body (22c) is supported by the valve body support portion (22b) is formed.

In a writing tool 1, a front shaft 5 is detachably provided on a rear shaft 6 containing an ink absorbent body 7. A filling part 51 is provided on an outside surface of a rear part of the front shaft 5. The filling part 51 detachably fits to a fitted part 61 formed on an inside surface of an opening part of the rear shaft 6. The filling part 51 has an outward-facing pressure contact part 53 and a radially penetrating slit 54. The fitted part 61 has an inward-facing pressure contact part 63. The front shaft 5 and the rear shaft 6 are brought into a pressure contact with each other when the front shaft 5 and the rear shaft 6 are fitted to each other.
