A newly filed patent (Publication Number: US20230414334A1) describes an interdental cleaning tool with unique features. The tool includes a base material portion with a base section and a shaft section, which extends into a transition section and a distal end section. The distal end section has a true-circle cross-section and is covered by a soft portion with projections. Importantly, the proximal end region of the shaft section has varying outer cross-sectional dimensions, with the second dimension being smaller than the first, creating an innovative design for effective interdental cleaning.

Furthermore, the patent claims specify additional details such as the orientation of the outer cross-sectional dimensions, the ratio between the two dimensions, and the minimum size of the second dimension. The soft portion of the tool is also required to have a minimum length along the shaft section. Additionally, the ratio of the outer cross-sectional dimensions is designed to gradually increase from the distal end region towards the proximal end region of the shaft section, enhancing the cleaning efficiency of the tool. These unique features aim to provide an improved interdental cleaning experience for users, highlighting the innovative design and functionality of the patented tool.
