Reusable travel toothbrush

Abstract

A travel toothbrush features a unique channel configuration designed to optimize the flow of high-viscosity toothpaste from a cartridge to the bristles of a brush tip. The channel includes an upstream section with a large cross-sectional area, a neck section with a reduced cross-sectional area, and a downstream section that expands back to a larger cross-sectional area. This geometry increases pressure in the neck section, enabling efficient dispensing of toothpaste, even at high viscosities, without requiring specialized formulations. The plunger, advanced by either a screw mechanism or manual pressure, ensures consistent toothpaste flow through the channel. The toothbrush's compatibility with standard commercial toothpaste and its ability to deliver controlled dispensing make it user-friendly and ideal for travel. The channel's adaptable cross-sectional shapes—round, circular, or oval—further enhance flow performance while maintaining ease of manufacturing and hygiene. This innovative design combines portability, efficiency, and versatility for everyday oral care.
