Abstract: An elongated preferably plastic handle has a sleeve lock on the tip end. When a twisted wire brush is placed in the handle, there is a guy wire effect from the sleeve which holds the brush firmly in place, as the sleeve stretches slightly over a bent end of the twisted wire of the brush. The inventive handle also holds the end of a wooden toothpick, which may be broken without leaving any exposed jagged fibers which could form splinters.

Abstract: A floss holder includes a bobbin of preferably unwaxed floss which feeds through a chamber containing a medication, such as fluoride. While in the chamber, the floss passes through a number of bearing surfaces for squeezing the medication into the floss without disturbing the lay of the fibers in the floss. After leaving the medication chamber, the floss passes out of the floss holder, over a stand-off prong and to a cutter. A clutch may be provided in the bobbin to maintain a floss tension throughout the medication chamber.

Abstract: A spool of thread, such as dental floss, is housed in a holder, preferably made of plastic. The thread or floss is wound on a bobbin having a hollow, cylindrical hub area. A clutch for controlling the bobbin rotation comprises a split post having an enlarged cross section near the center thereof. The split post fits into the hollow, cylindrical hub area of the bobbin with the post squeezed slightly to provide a desired amount of friction between the central post and the cylindrical hub walls. The friction keeps the bobbin from unwinding; however, the friction is not so great that it keeps the thread or floss from pulling smoothly and evenly from the bobbin.

Abstract: A spool of thread, such as dental floss, is housed in a two-part shell or holder, preferably made of plastic. The floor on the bottom one of the shell parts includes a platform to provide a bearing surface for enabling rotation of the spool with a minimum of friction. The top of the upper shell part includes at least one finger which depends far enough to drag, with predetermined friction, against the top of the spool. This friction is sufficient to prevent a random unwinding of the spool and yet small enough to preclude any substantial impedance to the withdrawal of a desired amount of thread from the spool.
