  • Patent number: 4706843
    Abstract: For sequentially dispensing individual closed loops of a narrow, easily tied, flexible material, such as dental floss, a chain having such closed loops as respective links thereof is made up by pressing a loop length of the flexible material into substantially rectilinear formation, loosely forming a knot in an end thereof, inserting a loop end of another so-pressed loop length into the loosely formed knot of the first loop length, tightening the knot to provide a slip-free-until-pulled-to-separate-loops joinder between the thus formed loop links and repeating this with additional loop lengths at either or both ends of the first-joined loop length until a chain of desired length is formed. Individual loop links are dispensed by grasping a terminal loop link of the chain and pulling it free of the chain while holding the knot that embraces the unknotted end of the next loop link of the chain.

  • Patent number: 4348439
    Abstract: A package is provided of wound strand of filaments coiled in layers, into a tubular configuration, with a sheet material covering of ionic polymer that has a surface attraction to the strand, for keeping the strand against the sheet material or film during unwinding of the strand from the package, completely through to the end of strand removal from the package. Electrostatic charge is induced on the strand and sheet material, to create electrostatic attraction at their common interface, for holding the strand to the sheet material and preventing the last portion of a strand package that is being unwound, from becoming tangled. Accordingly, this electrostatic attraction causes the film to support the outer strand coils in the package as the strand is withdrawn from the package, thereby preventing coils from slumping or falling together and becoming tangled.
