In order to provide a writing instrument applicable to an applicator, in which a writing or applying direction can be visually recognized in a broad range at a visual part of a tip, the writing instrument is endowed with a constitution in which a tip is equipped with a porous member as a writing part and a holding member holding the above porous member and having at least one liquid guiding part for feeding an liquid to the writing or applying part, which comprises a relay porous member for feeding a liquid contained in a instrument main body to the liquid guiding part provided in the holding member 55 and in which the holding member is a visible part wherein an area ratio of the above visible part on the front or side face is 40% or more of the tip protruding from a tip part.

First claim

Opening claim text (preview).

The invention claimed is: 1. An applicator in which a tip is equipped with a porous member as an applying part and a holding member holding the above porous member and having at least one liquid guiding part for feeding a liquid to the applying part, which comprises a relay porous member for feeding a liquid contained in an applicator main body to the liquid guiding part provided in a central part of a longitudinal direction of the holding member and in which the holding member is a visible part enabling to visually recognize an applying direction, wherein an area ratio of the above visible part on a front face is 40% or more of the tip protruding from a tip part of the applicator main body, and an area ratio of the visible part on a side face of the holding member in the tip is 40% or more, the liquid guiding part is less than a holding member side cross-sectional area of the applying part or less than a holding member side cross-sectional area of the relay porous member, and a clap part is formed between a step part and the relay porous member with a clearance in the range of 0-2 mm. 2. The applicator as described in claim 1 , wherein the liquid is a cosmetic composition having a viscosity ranged from 1 to 15 mPa·s.
