Problems solved by technology

In order for the roller to turn freely, a gap must be provided between the roller and the tube, with the risk that ink that is too mobile may pass through this gap and flood into the contact area between the roller and the substrate it is abutting against, thereby leave marks and smudges
[0005] Additionally, the valves and / or porous elements in the tubing may become clogged in the closed position (so that ink can no longer flow), or clogged in the open position (so that the writing instrument keeps leaking ink), both of which are detrimental to the normal operation of the writing instrument

Embodiment Construction

[0038] figure 1 The writing implement 1 in 4 has a tubular body 2 that is elongated along the main axis X, and this tubular body has an inner cavity 3 for liquid ink 4, especially referring to Fig. 4 , a part of the inner cavity is cut off in this figure 3.

[0039] As shown in Figures 3 to 5, the inner cavity 3 is a removable and replaceable modular barrel, which is just inserted between the front part 5 and the rear part 6 of the tube body 2. When the tube body 2 is assembled, the inner cavity 3 The surface is flush with the front 5 and the rear 6 ( figure 2 ).

[0040] As shown in particular in FIG. 4 , the front part 5 has at its end remote from the rear part 6 a fork-shaped front end 7 comprising two parallel arms 8 and 9 each having on its inner surface 10 an axis extending parallel to the main axis X. slot 11.

[0041] The tool 1 is preferably a marker pen or a line drawing pen, and also includes a writing device 12, which includes a support 13 with two bifurcation...

Abstract

A writing tool comprises a body (2) provided with an ink container (3), an inking element (16) mounted on the end of the body (2) and a feeding device (19) consisting of a tube which is provided with an inner wall, connects the container (3) to the inking element (16) and penetrates into the container (3) through an opening, a valve (22) comprising a jamb (32) which is received in said tube and extended by a head (31), wherein the valve is slidingly mounted between a closed position in which said head (31) is applied to a shoulder bordering said opening and an open position in which the head (31) is remote from the shoulder. An interstice is arranged between the jamb and the tube inner wall in such a way that said jamb projects from the tube.

Description

technical field [0001] The invention relates to a writing implement. Background technique [0002] Japanese Patent Application Publication No. JP-07-214968 discloses a writing implement, including an ink cavity, a roller, a pipeline connecting the cavity and the roller, and a valve that can move between a closed position and an open position, The valve closes the tubing in the closed position and communicates the lumen to the rollers in the open position. A porous element is provided in the conduit between the roller and the valve. The valve is pierced with a hole which, in the open position, allows ink to flow from the lumen to the porous element which in turn inks the roller. [0003] Writing instruments of this type are satisfactory, but have some disadvantages. [0004] First, if figure 1 and 2 As shown in the above application, a portion of the roller is located within the conduit carrying the ink flow. In order for the roller to turn freely, a gap must be provided...
