Writing, drawing, marking and/or painting utensil or cosmetics implement or input device for contact-sensitive surfaces, and method for producing the same
A writing, drawing, marking and/or painting utensil or cosmetics implement or input device for contact-sensitive surfaces, wherein the utensil/implement/device includes at least one shank element made of plastics material or a plastics-containing wood substitute. The at least one shank element has a surface, or in that the at least one shank element has a surface which is sheathed in a material layer having a cover surface. The surface of the shank element or the cover surface of the material layer is in the form of a haptic and/or non-slip layer. The haptic and/or non-slip layer has a structure formed in one piece with the shank element and/or the material layer. The structure is formed by corrugation.
1. A method for producing a writing, drawing, marking and/or painting utensil or cosmetic implement or input device for touch-sensitive surfaces, wherein the utensil comprises at least one shaft element formed from plastic material or plastic-containing wood substitute, wherein the at least one shaft element has a surface or the at least one shaft element has surface which is sheathed with a material layer having a covering surface, wherein the surface of the shaft element or the covering surface of the material layer is formed as a tactile and/or non-slip layer, wherein the tactile and/or non-slip layer has a structure, wherein the structure is formed in one piece with the shaft element and/or the material layer, and wherein the structure is formed by a corrugation, the method comprising the steps of:
cascade extrusion, wherein a bare pencil, having a lead, optional bonding agent and a shaft element, is extruded into a rod preform;
freezing a geometry of the rod preform by cooling;
applying a deformable or corrugatable material layer to the rod preform by a second transverse extrusion; and
expanding the deformable material layer into cavities of a corrugator.
2. A method for producing a writing, drawing, marking and/or painting utensil or cosmetic implement or input device for touch-sensitive surfaces, wherein the utensil comprises at least one shaft element formed from plastic material or plastic-containing wood substitute, wherein the at least one shaft element has a surface or the at least one shaft element has a surface which is sheathed with a material layer having a covering surface, wherein the surface of the shaft element or the covering surface of the material layer is formed as a tactile and/or non-slip layer, wherein the tactile and/or non-slip layer has a structure, wherein the structure is formed in one piece with the shaft element and/or the material layer, and wherein the structure is formed by a corrugation, the method comprising the steps of:
extrusion of a shaft body formed as a hollow profile into a rod preform;
freezing a geometry of the rod preform by cooling;
applying a deformable or corrugatable material layer to the rod preform by a second transverse extrusion; and
expanding the deformable material layer into cavities of a corrugator.
