One-use toothbrush assembly with external plug for releasing toothpaste from the interior, and method for using the same

摘要

A disposable toothbrush assembly has a special hollow handle that contains enough toothpaste for one use. The handle includes a dispensing orifice, preferably at the head. An external plug seals the orifice, and thus also the toothpaste from the exterior. The plug is manually removable to unseal the orifice. A compressed spring within the handle can be released by removing a stop. This causes a piston at the end of the spring to eject the toothpaste through the dispensing orifice on the bristles. The stop is advantageously formed integrally with the plug.
