  • Patent number: 4986289
    Abstract: A dental hygiene product in the form of a packet having a front panel and a back panel containing a pre-cut length of dental floss thread stored as a coil. The packet is severable into first and second packet portions, and opposite ends of the thread are affixed to respective packet portions which, after being severed, form grip tabs to facilitate withdrawal and use of the floss thread. A perimeter slit helps start the tearing of the packet. A plurality of packets may be constructed in strip-wise and matrix array configurations, and the packets may be separable along perforations. When constructed as a packet set, a single thread may define coiled portions for respective packets, and cuts may be made to sever the thread into thread units. A layer of tacky material may be disposed on a portion of the interior surface of one of the front and back panels to initially adhere the dental floss thread in a selected configuration on the interior surface of one of the panels.
