Title:
TOOTHBRUSH AND MANUFACTURING MOLD THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/090795
Kind Code:
A1
Abstract:
A toothbrush and a manufacturing mold thereof: the toothbrush consists of a handle, a handle head (200) and bristles (20); the handle head (200) and the bristles (20) are composed by integrally forming the thermoplastic bristles and the handle head by means of injection molding processing, and bristle tips (21) have a forked two-tip structure. By using the toothbrush having integrally injected two-tip bristles, the density of the bristle tips is doubled, increasing the contact area of the bristles and the tooth surface, improving cleaning intensity manyfold, and reducing pressure on the gums and enamel, thereby providing a more comfortable cleaning process. The toothbrush may adopt a bristle structure having a thick root and a thin tip, guaranteeing the strength of bristles while also reducing the rigidity of the bristles, thereby being more beneficial in protecting the teeth and causing the bristles to not bend easily.
