Abstract
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.
Claims20
A writing instrument, comprising:
- 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;
- and
- an elastic part positioned between the nib and the porous membrane, the elastic part extending beyond an end 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.
A method for manufacturing a writing instrument, wherein the writing instrument comprises:
- a tubular body;
- a porous membrane or mesh surrounding at least a distal portion of a 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;
- and/or
- a cap assembly, further comprising:
- the porous membrane or mesh;
- an elastic part comprising at least one writing orifice and surrounding at least a distal portion of the nib, the elastic part positioned between the nib and the porous membrane;
- wherein a wall thickness and a radius of the writing orifice are configured such that in a non-writing position the elastic part extends beyond of the nib along a longitudinal axis of the writing instrument, and wherein, in a writing position, the cap assembly is configured to contact the nib, thereby allowing ink to penetrate through the porous membrane or mesh;
- wherein the method comprises:
- connecting the porous membrane or mesh and/or the cap assembly to the tubular body using permanent interconnection or non-permanent interconnection.
