To provide an applicator capable of exchanging air after discharging the application liquid even if the applicator is equipped with a valve mechanism that opens its valve by increasing the internal pressure of the ink tank.

An applicator includes a valve mechanism that communicates an application liquid tank and an applying part. The valve mechanism has at least a valve stem and a valve holder for holding the valve stem therein, the application liquid can flow through a gap between the valve stem and the valve holder, the valve stem is formed with an air exchange hole, and, the air exchange hole can be opened and closed by an opening/closing member that opens/closes when the pressure on the application liquid tank side becomes negative or positive compared to that on the applying part side.

The invention relates to a dev ice for applying a viscous substance, in particular for the purposes of cosmetics, writing, painting, drawing, and/or marking, with a tank (40) for tire substance, an application apparatus (2), and a conveying device (3), which is configured such as to convey the substance out of the tank (40) to the application device. According to the invention, provision is made for the conveying device (3) to comprise a cylinder (10), a piston (30) arranged such as to be axially displaceable in the cylinder, a pump plunger (20) for the axial displacement of the piston (30), a first connection channel (41) between the cylinder (10) and the tank (40), and a second connection channel (21) between the cylinder (10) and the application apparatus (2), the piston (30) to be adjustable in relation to the pump plunger (20), for the piston (30) to open or close the first connection channel (41) depending on the setting in relation to the cylinder (10), and for the piston (30), depending on the position in relation to the pump plunger (20), to open or close the second connection channel (21).

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.

Provide is a direct liquid type writing-brush pen that is equipped with a valve mechanism; and with which the ink tube is of replaceable cartridge type, and the writing brush tip is always impregnated with an appropriate amount of ink while the ink leakage being suppressed, whereby an excellent feeling of writing can be always given. A direct liquid type writing-brush pen, including a barrel, which holds a writing brush tip unit at the distal end part thereof; an ink cartridge, which is slidably and detachably fitted into the barrel from the basal end side thereof; a cap, which covers the writing brush tip unit; and a stopper, which is fitted to the basal end part of the barrel to slidably support the basal end part of the ink cartridge, which is protruded from the basal end side of the barrel, wherein, in the distal end part of the ink cartridge, a valve mechanism, which accommodates a valve core in a valve seat, is incorporated; in the valve seat, the distal end part of the valve core is removably connected to the basal end part of a relay core, which constitutes the writing brush tip unit; and on the circumferential face of a smaller diameter part of the valve seat, a sealing strip is formed.

A writing tool has a pen tube, a capillary unit, and a dispensing unit. The capillary unit is mounted in the pen tube, and is connected to a nib. The dispensing unit is mounted in the pen tube, and has a communicating tube and a pressing segment connected to the communicating tube. The pressing segment has at least one connecting arm connected to the communicating tube. A dispensing interval is formed between the communicating tube and a periphery of the pressing segment. The communicating tube contacts the capillary unit to make the capillary unit form different compression densities via the pressing segment and the dispensing interval, thus facilitating dispensing ink downward easily through the dispensing interval and providing a better occlusion effect to further avoid ink leakage.

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.
