Claims14
Writing element (20) for a writing instrument (1) comprising an elongated stem (10) having a grip portion (12) longitudinally delimited by an end portion (14);
- said stem (10) having a longitudinal cavity (16) of given extension;
- said writing element (20) having a body (21) delimited by an end (22) provided with a point (23) suitable, in use, to draw signs on paper through oxidation;
- said body (21) having an elongated coupling portion (24) provided with respective connecting means (26) suitable to engage said cavity (16);
- characterized in that said end (22) is covered by a cover (28) comprising said point (23) and is made of a composite metal alloy suitable to trace signs on paper through oxidation of the composite metal alloy.
Writing instrument (1), comprising an elongated stem (10) having a grip portion (12) longitudinally delimited by an end portion (14);
- said stem (10) having a longitudinal cavity (16) of given extension designed to house a writing element (20), in a stable and selectively releasable manner, at the side of said end portion (14),
- characterized in that
- said writing element (20) has a body (21) delimited by an end (22) provided with a point (23) suitable, in use, to draw signs on paper through oxidation;
- said body (21) having an elongated coupling portion (24) provided with respective connecting means (26) suitable to engage said cavity (16);
- characterized in that said end (22) is covered by a cover (28) comprising said point (23) and is made of a composite metal alloy suitable to trace signs on paper through oxidation of the metal alloy.
Method of production of a writing element (20) for a writing instrument comprising an elongated stem (10) having a grip portion (12) longitudinally delimited by an end portion (14);
- said stem (10) having a longitudinal cavity (16) of given extension designed to house a writing element (20), in a stable and selectively releasable manner, at the side of said end portion (14),
- characterized in that
- said writing element (20) has a body (21) delimited by an end (22) provided with a point (23) suitable, in use, to draw signs on paper through oxidation;
- said body (21) having an elongated coupling portion (24) provided with respective connecting means (26) suitable to engage said cavity (16), wherein said end (22) is covered by a cover (28) comprising said point (23) and is made of a composite metal alloy suitable to trace signs on paper through oxidation of the metal alloy,
- the method being characterized by comprising:
- a step of providing a bi-component metal alloy, a step of melting a first component of said metal alloy, a step of melting a second component metal of said metal alloy, and a step of pouring the melted alloy into a mold to form the body (21) provided with an end (22) that is made of said metal alloy and is provided with a point (23) suitable to trace signs on paper through oxidation.
