Definitions

  • the screw cap according to the invention with the characterizing features of claim 1 the advantage that the sealing strip when the cap is placed on the Containers not only folded and squeezed but pulled apart and stretched around the mouth area. Tensioning is achieved by the sealing strip on one end is attached to the cap and the other end with the bulge-like thickening between the mouth area of the Container and a sealing ring bead on the Screw cap is jammed.
  • the beaded Thickening lies on the side facing away from the base of the cap Face of the sealing ring bead.
  • this runs end of the sealing strip facing the cap bottom in axial direction of the screw cap. This is ensures that the sealing strip when putting on the cap is redirected to the container and thereby to the outside of the estuary area.
  • the sealing strip extends in the bottom of the cap opposite direction at least to that of the cap bottom next thread.
  • the diameter is on the End facing away from the cap bottom is smaller than at the end End facing the cap bottom.
  • the length of the weather strip in the axial direction is for contacting the mouth area necessary from all sides. The change in the diameter of one end to the other ensures that the bead-like Thickening of the sealing strip when the cap is put on creates the container on the inside of the mouth area and between the inside and the sealing ring bead becomes.
  • the diameter of the sealing strip matches this the end facing away from the cap bottom approximately with the Outer diameter of the sealing ring bead corresponds.
  • sealing shoulders provided on the cap base. These worry for an additional seal between the Screw cap and the container.
