摘要： An applicator which includes a rear barrel 1; an ink occlusion element 10 accommodated in rear barrel 1; an ink occlusion element receiver 20 opposing the front end part of ink occlusion element 10; a see-through front barrel 30 fitted to the opening of rear barrel 1, a detection tube 40 inserted in front barrel 30 for flowing ink from ink occlusion element 10; a joint core 50 supported by detection tube 40 and flowing out ink from ink occlusion element 10; and a pen core 60 supported by detection tube 40 and disposed on the opposite side of joint core 50 with a detection space 63 from joint core 50. Detection tube 40, joint core 50 and pen core 60 are formed into an integral structure. It is possible to exactly grasp the ink end state in a visual manner, based on the presence/absence of ink in detection space 63 of detection tube 40.

摘要： A writing instrument equipped with an exchangeable inner pen filled with an ink containing a solvent having a vapor pressure of 1 to 50 mm Hg (20° C.) in a writing instrument main body which is a barrel part, wherein the inner pen described above has a pen tip comprising a fiber feeder or a plastic feeder, and the above pen tip is coated with a substance having a vaporization-inhibiting action in an amount of 0.01 to 20% by weight in terms of a weight ratio based on the pen tip. It is more effective to further add a substance having a vaporization-inhibiting action to the ink. The substance having a vaporization-inhibiting action includes glycerin derivatives, polyoxyethylenesorbit fatty acid esters, alkyl phosphates, waxes and lecithin.
