A writing implement is provided which is designed to draw lines using capillary action, wherein the width of the line can be freely adjusted while the line is being drawn and it is possible to draw lines of almost the same width at the beginning of the use of the writing implement as at the end of use. A felt-tip pen 1 is provided with an ink reservoir 11, a collector 17, and a core 29 for drawing by capillary action the ink that has been dispensed by the collector 17, dispensing the drawn ink from the tip, and adhering same to a paper surface. Even in repetitive writing, the rate of variability in the width of the lines drawn at the end of use with respect to the width of lines drawn at the beginning of use is 10% or less.

A liquid ink instrument, including: a pen body, a writing element mounted on the head of the pen body, an ink absorber mounted at the rear end of the writing element; a fiber ink feeder mounted in the body penetrates the ink absorbing body, the front end in contact with the writing element, the rear end communicated with the ink cartridge; at least one air-liquid balancer in the axial direction, the air-liquid balancer installed between the recited fiber ink feeder and the body; having one or more air-liquid exchange grooves penetrating through the outer circumferential surface; having an overflow groove on a radial surface of the air-liquid balancer, one end contacted to fiber ink feeder, and the other end communicating with air-liquid exchange groove; a gas-free fit or an interference fit adopted between the outer circumferential surface of the fiber ink feeder and the inner wall of the air-liquid balancer.

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.

Disclosed is a direct-liquid writing instrument. Two ends of a penholder (1) are provided with a writing portion (11) and an ink storage portion (12) respectively. A nib (3) is partly inserted into the writing portion (11). A first baffle (41) and a second baffle (42) of an adjusting portion (4) are spaced apart so that an air barrier layer (43) is formed between the two baffles. The first baffle (41) is in contact with the ink (13) of the ink storage portion (12). The second baffle (42) is adjacent to the writing portion (11). An ink feeder (2) passes through the first baffle (41), the air barrier layer (43) and the second baffle (42). The first baffle (41) is provided with a first air-guiding channel (8). A second air-guiding channel (7) is provided between the second baffle (42) and the ink feeder (2). At least one gap is formed between the second air-guiding channel (7) and the ink feeder (2). The present direct-liquid writing instrument has the advantages as follows: 1) a large storage capacity, low ink residuals, and fluency in writing; 2) prevention to leakage even under significant variation of external temperature and pressure; 3) simple and stable in structure, resistant to pressure difference and temperature difference, and convenient for transportation; 4) high ink utilization rate, convenient for usage, and less waste and environment pollution.

An applicator that causes a liquid applying material accumulated inside, for example, a cosmetic tool, such as an eye liner and an eyebrow pencil, or a gray-hair partially dyeing tool for hair, an eyebrow, or a similar part, to infiltrate into an application portion to use this liquid applying material for application or drawing from a distal end application portion.

A pen including an ink reservoir to store an ink; a pen tip which has a proximal end and a distal end opposite to the proximal end and applies an ink to a coating target; an ink guide to guide the ink in the reservoir toward the pen tip; and a holder part which has a through hole through which the pen tip is inserted and holds at least the proximal end of the pen tip while exposing the distal end of the pen tip with the pen tip inserted through the through hole. The holder part includes: an ink holding part capable of holding the ink from the ink guide and formed at least partially around a circumference of the through hole; and a first opening opening on an inner circumferential surface that defines the through hole and communicating with the ink holding part.
