Provided is a writing tool with an anti-drying device, comprising a pen holder (110), a pen tip (1) arranged in the pen holder (110), an ink cartridge (130) and a pressing rod (150). The writing tool with the anti-drying device further comprises an anti-drying device (200), wherein the anti-drying device (200) comprises a switch sleeve (210), a lifting cap (220), a tapping spring (214), a rotatable sealing cap (230), a sealing pad (240) and a support spring (244). The switch sleeve (210) is inserted in the pen holder (110), an elastic part (211) is respectively arranged on each of the two sides of the upper end of the switch sleeve (210), the switch sleeve (210) is further provided with a lifting groove (212) extending to be distributed on the elastic part (211), a rotating groove (213) is arranged on the side of the lower end of the switch sleeve (210); the lifting cap (220) is inserted in the switch cover (210), a support protrusion (221) is respectively arranged on each of the two sides of the upper end of the lifting cap (220), and the rotatable sealing cap (230) is used for turning so as to open or close an access hole (241).

The present invention relates to a retractable washable marker device. The device is primarily comprised of a barrel, a thrust device, and a marker member saturated with an ink having a tip. The tip can be extended/retracted into the barrel. When not in use, the tip is retracted within the barrel and enclosed in the barrel by at least one flap that covers a first opening of the barrel. In this manner, air is prevented from entering the barrel and drying out the tip and marker member.

A marking pen, comprising: a shaft cylinder; a porous pen core accommodated in the shaft cylinder, and configured to project from, and retract into, an opening part provided at a tip end of the shaft cylinder; an inner cotton accommodated in the shaft cylinder, and filled with an aqueous ink composition to be fed to the pen core, the aqueous ink composition including a water soluble organic solvent in an amount of from 20 mass % to 60 mass %; and a delivery mechanism configured to cause a tip end of the pen core to project from, and retract into, the opening part.

A portable kit for storing a pen according to the present invention includes a base in which an accommodation portion is famed. The pen is fastened to the accommodation portion, and is coupled to a coupling kit having a shape corresponding to that of the accommodation portion and accommodated in the accommodation portion. A grip portion is formed on the coupling kit, and allows the pen to be withdrawn from or retracted into the base in such a manner that the grip portion is pushed with a finger.

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.

The present invention includes a shaft cylinder having an opening at a front end thereof, a tip holder movable in an axial direction of the shaft cylinder, a tip projectable and retractable in conjunction with a movement of the tip holder, an annular member fitted on the tip holder and axially movable, and an elastic member connecting the tip holder and the annular member so that they are movable relatively to each other. A contact surface tapered toward the front end is formed on an outer periphery of the annular member. A cutout reduces an inner diameter of the annular when a load is received by the contact surface. A guide surface is formed on the part of the inside surface of the shaft cylinder. The contact surface receives the load from the guide surface in conjunction with the movement of the tip holder toward the front end side.
