  • Patent number: 4403625
    Abstract: An inexpensive disposable buccal hygenic device is disclosed. An elongated cylindrical wooden body of a generally circular cross-section is pointed at each of its ends and is of such a size that the body is comparable functionally to a conventional toothpick. The elongated body is divided transversely into two separable members of generally similar length. The first member has a reduced cross-section for a distance immediately adjacent to the transverse division. The second member has an internal cavity therein contiguous with the transverse division. The internal cavity is adapted to fit slidably over the reduced cross-section portion of the first member and is of a depth at least equal to the distance of reduced cross-section on the first member so that a cavity remains when the first member is inserted fully into the second member.
