Abstract: A flossing tool includes a handle, a neck and a head at the distal end of the neck. A spool of floss is placed in a compartment within the handle with the free end of the floss being extended from the compartment and over a series of ridges traversing the neck. The floss is wound about four lobes on the head so as to present first and second laterally spaced-apart stretches of floss. The free end of the floss is then wound about a pin on the neck so as to place initial tension on the wound floss. A locking device engages the ridges on the neck so as to clamp the dental floss to the neck and place additional tension on the wound floss. Accordingly, first and second opposed stretches of tensioned floss are available to clean the upper and lower teethlines. A cutter blade on the neck allows the user to sever the end of the floss upon use. The angles between the handles, neck and floss head are selected so as to assist the user in flossing.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is as follows:     1. A dental floss tool comprising:
  • an elongated handle having a first end and a second end;
  • a compartment in said handle between said first end and said second end for holding a supply of dental floss;
  • a slot formed in said handle adjacent said compartment which provides a path for dental floss to extend from said compartment;
  • a neck having a first end and a second end, the neck first end being joined to the first end of said handle such that the neck extends from said handle;
  • a plurality of ridges formed on and traversing said neck, wherein floss extending from said slot is adapted to pass across said ridges;
  • a floss head attached to said second end of said neck, said head comprising:
    • an elongated head body having a series of four spacedapart lobes extending therefrom;
    • a channel in each of said lobes for holding said floss such that there are first and second longitudinal stretches of floss wound about said lobes;
  • a pin extending from said neck for wrapping of a free end of the dental floss about said pin in a manner to place an initial tension on the dental floss wound about said lobes;
  • a clamping device pivotally attached to said neck between a first position displaced from said ridges and a second position for engaging said ridges and floss passing thereover, said clamping device adapted to place additional tension on said dental floss wound about said lobes when in said second position.
