Writing, drawing, painting or cosmetic device comprising a honeycomb body, and method for producing the honeycomb body or the device comprising a honeycomb body
A writing, drawing, painting or cosmetic device having at least one honeycomb body formed from a plastic material and/or a composite material consisting of a natural material and a plastic material. The at least one honeycomb body contains a plurality of hollow longitudinal structures that are axially parallel to one another.
1. A writing, drawing, painting or cosmetic device, comprising: at least one honeycomb body, the at least one rigid honeycomb body being formed from a composite material consisting of a natural material and a plastic material, wherein the at least one honeycomb body includes a plurality of hollow longitudinal structures axially parallel to one another, wherein the hollow longitudinal structures form a tube structure; and a coloring lead, wherein the at least one honeycomb body is formed as an encasement of the coloring lead.
2. The device according to claim 1 , wherein the plurality of hollow longitudinal structures of the honeycomb body are oriented parallel to a longitudinal axis of the device.
3. The device according to claim 1 , wherein the longitudinal structures in the honeycomb body have cross-sections that are round, elliptical, polygonal and/or star-shaped.
4. The device according to claim 1 , wherein the device is a lead pencil, colored pencil or cosmetic pencil.
5. The device according to claim 1 , wherein the composite material consisting of a natural material and a plastic material contains
at least 50% by weight of natural material(s),
0 to 20% by weight of inorganic filler(s),
0 to 10% by weight of adhesion-promoting agent,
0 to 10% by weight of color pigment(s),
0 to 10% by weight of wax(es),
0 to 5% by weight of additive(s),
a remainder being formed by plastic material(s) as polymeric binder.
6. The device according to claim 1 , wherein the plastic material of the composite material consisting of a natural material and a plastic material is a polymer selected from the group consisting of polyolefins, polystyrenes, styrene acrylonitriles, acrylonitrile butadiene styrenes, polycarbonates, polyvinyl chloride and/or from the group of biopolymers.
7. The device according to claim 1 , wherein the device has an outer contour that is round or polygonal.
8. A method for producing a writing, drawing, painting or cosmetic device according to claim 1 , comprising the step of extruding the honeycomb body.
9. The device according to claim 1 , wherein the lead is held non-displaceably in the encasement.
10. The device according to claim 9 , wherein the encasement and the coloring lead are coextruded.
11. The device according to claim 1 , wherein the natural material of the composite material consisting of a natural material and a plastic material consists of wood and/or cellulose.
12. The device according to claim 11 , wherein the wood and/or cellulose is/are present in powder form, meal form and/or fiber form.
13. A method for producing a writing, drawing, painting or cosmetic device according to claim 9 , comprising the step of coextruding the honeycomb body and the lead.
