Document Type and Number:
Japanese Patent JP5261184
Kind Code:
B2
Abstract:
The present invention provides a method of tapering bristles for toothbrushes and a toothbrush having bristles manufactured using the method. One method disclosed in the present invention includes setting bristles made of polyester in a head insert, and fastening the bristles to the head insert by thermally welding portions of the bristles, protruding from a back surface of the head insert, to the head insert. The method further includes coupling the head insert to a toothbrush body and tapering ends of the bristles by immersing the bristles in a chemical. The bristles can be securely set in the toothbrush body without an anchor. Furthermore, polyester bristles, which could not be set in toothbrushes having variously shaped setting rows due to excessively high stiffness, can be set in these types of toothbrush by the toothbrush manufacturing method of the present invention.
