Claims24
A writing instrument comprising:
- a body provided with an ink reservoir;
- an inker element mounted on said body;
- and
- a feeder device comprising:
- a duct connecting the reservoir to said inker element and opening out into the reservoir via an opening, said duct presenting an inside wall;
- and
- a valve having a tab received in said duct, the tab being extended by a head,
- wherein said valve is mounted to slide between a closed position in which the head is pressed against a shoulder bordering the opening so as to prevent ink from flowing, and an open position in which the head is located at least in part away from the shoulder so as to enable ink to flow through the opening,
- wherein a gap is formed between the tab and the inside wall of the duct,
- wherein the tab projects from said duct towards said inker element,
- wherein said inker element is movable between a writing position in which it urges said valve towards an open position to allow the ink to flow, and a rest position in which it allows said valve to occupy a closed position, and
- wherein said inker element is secured on a support mounted to slide relative to said body between a writing position in which said inker element urges said valve towards an open position to allow the ink to flow, and a rest position in which said inker element enables said valve to occupy a closed position.
