Abstract
A functional polymeric cutting edge structure and methods for the manufacturing cutting edge structures using polymeric materials are provided. A razor blade for use in a razor cartridge or a blade box for assembly in a razor cartridge frame may be formed using the present invention.
Claims23
A method for manufacturing at least one cutting edge structure comprising the steps of:
- providing a first polymeric material in liquid form in a container;
- providing at least one cutting edge template within said first polymeric material;
- curing said first polymeric material while said at least one cutting edge template is disposed in said first polymeric material to form a base structure;
- removing said template to obtain a cavity in said base structure;
- filling said cavity with a second material, said second material being a precursor for a polymeric material;
- curing said second material;
- and
- separating said base structure and said cured second polymeric material, said at least one cutting edge structure comprised of said cured second polymeric material.
5 more elements
A blade box comprising
- at least one cutting edge structure;
- at least one non-cutting edge structure coupled to said at least one cutting edge structure, both said cutting and non-cutting edge structures comprised of a polymeric material, said polymeric material produced by a precursor material for said polymeric material.
A razor blade comprising
- at least one cutting edge structure comprised of a polymeric material, said polymeric material produced by a precursor material for said polymeric material.
