  • Patent number: 4512354
    Abstract: In a dental floss applicator having a capstan controllable by the user for tensioning the floss and for periodically substituting a fresh floss strand segment for a previously used segment, an improved arrangement for severing floss and anchoring a floss strand end to the capstan as a result of a simple continuous movement of the strand by a user is disclosed. The capstan includes a slot for receiving a one piece metallic clip having a deformation so that the floss strand may be gripped between that deformation and one surface of the capstan slot as well as a cutting prong deformed from the general plane of the clip in the same general direction as the floss gripping deformation and presenting a relatively sharp surface to the floss as the floss is pulled into the gripping position between the deformation and slot.
