Document Type and Number:
WIPO Patent Application WO/2018/124298
Kind Code:
A1
Abstract:
[Problem] To provide a method for manufacturing an interdental cleaner, the method enabling, in a step for filling the inside of a mold with an elastomer, suppression of leakage of the elastomer out of a space provided to form an anti-slipping part in the mold. [Solution] The method for manufacturing an interdental cleaner comprises: a first step for forming a base part having a handle part and a shaft part (40) by filling the inside of a first mold with a composite material; and a second step for forming a cleaning part and an anti-slipping part by filling the inside of a second mold (200) with an elastomer, with the base part being placed inside the second mold (200). In the first step, the handle part is formed to have a base (24), a recessed section (26), and a raised section (28) raised from the surface of the recessed section (26). In the second step, the cleaning part and the anti-slipping part are formed by filling a second space with the elastomer from an area of the base part, with the area being positioned further toward the shaft part (40) side than the raised part (28).
