A refill for a writing felt pen, the refill comprising a deformable pouch and a nib inserted into the deformable pouch, the deformable pouch comprising a mix of dry absorbent polymer, fibers and dry ink.

A refill for a writing felt pen, the refill comprising a deformable pouch and a nib inserted into the deformable pouch, the deformable pouch comprising a mix of dry absorbent polymer, fibers and dry ink.

Provided is a pen including: an ink reservoir that stores an ink including decorative particles and a pen tip section. The ink reservoir includes a tubular casing member having liquid blocking properties and an ink occlusion material disposed inside the casing member. The casing member has a first opening end and a second opening end. The ink occlusion material includes multiple fibers disposed in the casing member and the multiple fibers respectively having one ends and other ends each disposed at a position corresponding to the first opening end or the second opening end of the casing member.

The present invention provides a liquid applicator, comprising: an applicating head, a buffer in communication with the outside air, a gas-liquid exchanger and a reservoir supplying a liquid to the gas-liquid exchanger. The gas-liquid exchanger has a wick, a liquid sealing tube covering on the outer peripheral wall of the wick, and a gas-liquid channel disposed between the wick and the liquid sealing tube; the buffer covers on the outer peripheral wall of the liquid sealing tube, and capillary pressure of the liquid sealing tube is greater than capillary pressure of the buffer by 30% or more. The liquid applicator of the invention can effectively control the release of a liquid and prevent the liquid from leaking out, and features a simple structure, smooth application and easy manufacturing.

Provided a cosmetic applicator that can alleviate the shock at its barrel cylinder even if the center of gravity of the applicator is on the rear side. In the cosmetic applicator having an applying part provided at the front end of the barrel cylinder and a cosmetic stored in the rear of the barrel cylinder, a resilient member is mounted to the rear end of the barrel cylinder.

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.
