  • Patent number: 4275750
    Abstract: A practical and efficient self-contained toothbrush is disclosed. A brush element is provided which includes a hollow handle and a brush head integral to one end of the handle. The peripheral dimensions of the brush head do not exceed those of the handle when viewed axially. A hollow cap is attachable to the handle so that the cap encloses the brush head. A base is attachable to the end of the handle opposite from the brush head. A dentifrice container is attached to the base at one end and has an opposite end with an opening for the dispensing of dentifrice. The container projects from the base so that the container is located within the hollow handle when the base is attached to the handle. The external peripheral dimensions of the container are contoured to match the internal dimensions of the hollow handle to maximize the size of the container and seal the opening of the container when it is enclosed by the handle.
