摘要

"Writing instrument, a cap end for use in same, and methods of manufacturing a buffer with a buffer end element integral and to manufacture a writing instrument.A writing instrument, with a tip of writing which responds to the pressure applied during the writing.Through the use of a damper element integrally molded with another part of the writing instruments.In a preferred form of execution, a writing instrument comprises a cylinder.A cartridge with a writing tip, and a buffer at the end to a damper element molded integrally with the cap end.The cartridge can be maintained in the cylinder via the damping element, which is attached to the proximal end of the cylinder. The buffer end can be molded by an injection moulding process.A stop element may be provided to inhibit or prevent the compression of the shock absorber element after a predetermined degree of compression of the shock absorber element.The damping element may have a spring rate variable.
