  • Zippers with sliders are made commercially in several forms.
  • the most common ones used on clothing have teeth which interlock.
  • the teeth may be made of metal or plastic.
  • Other types of plastic zippers have profiles and include a pair of male and female fastener elements in the form of reclosable interlocking rib and groove elements with a slider for opening and closing the rib and groove elements.
  • a pair of these male and female fastener elements extend along the mouth of the bag and these male and female elements are adapted to be secured in any suitable manner to the flexible walls of the thermoplastic film bag.
  • These elements may be integral marginal portions of such walls or they may be extruded separately and thereafter attached to the walls along the mouth of the bag.
  • a method of continuously providing such a fastener on the thermoplastic film is disclosed in U.S. Patent 3,462,332.
  • the sliders for opening or closing the reclosable fasteners are essentially ⁇ -shaped and adapted to be assembled with the fastener or zipper by an endwise assembly or by a relative transverse maneuver.
  • the slider is normally molded from a semi-hard plastic where there is enough yieldability in the side walls of the slider to provide sufficient flexibility to enable spreading apart of the terminal portions of the side walls of the slider so as to clear the interlocking rib and groove elements to permit assembly of the slider with the zipper by relative transverse movement.
  • the slider is formed from a metal die casting or a hard plastic, it is then necessary to rely upon the plastic deformation of the plastic zipper elements to permit the transverse assembly movement of the slider.

  • the wings 21 and 22 are hinged to the main slider body 20 by means of hinge structure 21a and 22a.
  • the hinge structure 21a and 22a is a relatively thin section of the plastic material as compared to the wall thicknesses of the wings 21 and 22 and the flexibility of the plastic material makes possible the use of the integral hinge structure 21a and 22a which is sometimes referred to as a "living" hinge.
  • the main body 20 is provided with depending structure in the form of two pairs of legs 20a, 20b and as may be seen in Figs. 2, 7 and 8 the wings or foldabie side walls 21 and 22 are positioned between the pair of the depending legs 20a, 20b on opposite sides of the slider 10.
  • the side walls 21 and 22 are snapped into position and held by molded latches to the legs at one or both ends of the slider.

  • the side walls 21 and 22 of the foldabie slider 10 are integral with the body portion 20 this provides for ease in assembly as distinguished from multiple part sliders. Also since the slider is made from plastic material it can be used on a food bag in a microwave whereas a metal slider cannot. While the preferred form of the invention has been described in connection with a living hinge other plastics which are not suitable for making a living hinge can be used. Thus more brittle plastics can be used as it is only necessary that the side walls be snapped into place once since the slider is not removed from the reclosable fastener elements once it is assembled.
