When the rear axial cylinder (3) is rotated, the cam cylinder (17) is also rotated, thereby the cam protrusion (18a) moves forward by means of the functions of the cam groove (17a) and the slit (18b), so that the slider (18) moves forward to cause the writing body (14) to move forward against a biasing force by the biasing member (15). The cam cylinder (17) and the rear axial cylinder (3) are fixed via the adjustment mechanism of rotational positions (17n).

A liquid applicator device is disclosed for dispensing a liquid. A dispensing mechanism defines a valve body hollow. The dispensing mechanism receives the liquid from a liquid container. A closure engages with the liquid container. An applicator tip slidably engages within the closure. A flared peripheral shoulder is coupled to a valve element. The flared peripheral shoulder is impressed against the valve body hollow for preventing the liquid from exiting the dispensing mechanism. The flared peripheral shoulder is displaced for permitting the flow of the liquid from the dispensing mechanism and to the applicator tip. In a first embodiment of the invention, the flared peripheral shoulder includes a non linear protrusion for preventing leakage of the liquid from the dispensing mechanism. In a second embodiment of the invention, a valve flow regulator is coupled to the valve element for controlling the flow of the liquid from the dispensing mechanism.

According to an aspect, a writing instrument is provided. The writing instrument includes a reservoir for storing writing ink, a nib arranged distally to the reservoir and in fluid communication with the reservoir, a porous membrane or mesh surrounding at least a distal portion of the nib, wherein, in a writing position, the porous membrane or mesh is configured to contact the nib, thereby allowing ink to penetrate through the porous membrane or mesh.
