Interdental cleaning tool with varying bristle hardness
The patent US11986086B2 describes an interdental cleaning tool designed for effective cleaning between teeth. The tool features a base portion with a shaft that is shaped to fit into interdental spaces. It includes two distinct cleaning portions: a top end side and a base end side. The top end side cleaning portion is equipped with a body that covers the upper part of the shaft and is adorned with a plurality of bristles that extend outward. Notably, the bristles on the top end side are characterized by a lower hardness compared to those on the base end side, which also has its own body and bristles. This design aims to provide a gentle yet effective cleaning experience.
Additionally, the patent outlines that the top and base end side cleaning portions may differ in hue, enhancing user experience and functionality. The base end side cleaning portion is specified to be constructed from a composite material that includes elastomer and a reinforcing material, which may contribute to its durability and effectiveness. The claims emphasize the distinct hardness levels of the bristles and bodies, suggesting a tailored approach to interdental cleaning that balances gentleness and efficacy.
