Document Type and Number:
WIPO Patent Application WO/2023/120163
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a brush molded body that makes it possible to improve the degree of freedom in terms of bending direction, achieve both excellent feel and dental plaque removal capabilities, and realize a tendency to not remain warped. The present invention has a head base portion formed from a soft resin, and a plurality of filaments that extend in a long-axis direction from a supporting surface positioned on the thickness-direction front side of the head base portion. The filaments have a first region that has a flat shape in a cross-section orthogonal to the long-axis direction, and a second region that has a flat shape in a cross-section orthogonal to the long-axis direction and that is different from the first region in terms of long-axis-direction position. A first long-side direction, in which the long side of the flat shape in the first region extends, is fixed in the first region. A second long-side direction, in which the long side of the flat shape in the second region extends, is fixed in the second region. The first long-side direction and the second long-side direction intersect when viewed in the long-axis direction.
