Abstract: A housing of a writing instrument for holding an elongated refill has a front portion with a sleeve body made of an inelastic shape-retaining material, carrying a jacket made of an elastic second material, especially to function as a grip. The grip is formed on the sleeve body and extends along a substantial axial length. The grip is affixed by injection of the second material through an opening at a front of the sleeve body forming a starting end of an adjoining axially extending injection channel. One or more radially or laterally oriented apertures in the sleeve body connect to the injection channel and deliver the second material to the outer surface of the sleeve body.

Abstract: The invention relates to a front section (1) of a housing of a writing implement. Said front section comprises a casing body (4) consisting of a shape-retaining substance and a jacket (8) consisting of a second substance, which forms a flat surface surrounding the casing body along a substantial part of said body's axial length. An opening (7) positioned at the front of the tip of the casing body (4) forms the starting point of an adjoining axial segment (7, 10, k1) of an injection canal (38, 39, 10, 24, 25) for the second substance.
