Abstract
A fountain pen comprising: an elongate hollow body defining an inner chamber designed to receive an ink container; a nib disposed at a first end of the hollow body; and a connection part connecting the inner chamber to the nib and defining an ink flow passage extending along a longitudinal axis (XX), the connection part comprising a valve opening and closing the ink flow passage, designed to selectively open and close the ink flow passage. The connection part comprises a striker interposed between the valve and the inner chamber and designed to engage with the ink container and allow a flow of ink between the ink reservoir and the nib.
Claims16
A fountain pen comprising:
- an elongate hollow body defining an inner chamber adapted to receive an ink reservoir;
- a nib arranged at a first end of the hollow body;
- and
- a connection part connecting the inner chamber and the nib and defining an ink flow passage extending along a longitudinal axis, the connection part comprising a valve for opening and closing the ink flow passage, designed to selectively open and close the ink flow passage,
- wherein the connection part comprises a striker interposed between the valve and the inner chamber and designed to engage with the ink reservoir and allow ink to flow between the ink reservoir and the nib,
- wherein the striker comprises a substantially cylindrical tongue extending along said longitudinal axis and defining a portion of the ink flow passage, said tongue comprising an end edge and an opposite end, said striker comprising a peripheral wall surrounding said opposite end and at a distance from the opposite end defining a space between the opposite end and the peripheral wall, wherein said space between the opposite end and the peripheral wall is adapted to receive the ink reservoir in a leak-tight manner.
