Definitions

  • the invention relates to a screw cap made of plastic material according to the preamble of claim 1.
  • Such screw caps differ from screw caps with a separately inserted sealing washer.
  • a sealing washer is not necessary in the generic screw cap, since the seal between the screw cap and the mouth area of the container is achieved by a sealing strip attached to the screw cap.
  • Screw caps consist of one part. From DE 197. 05 717 AI such a screw cap is known. A sealing strip arranged on the base of the cap deforms elastically when the container is closed with the screw cap. In the closed state, the sealing strip lies against the outer mouth area of the container. The sealing strip is pressed outwards through the container. The restoring force acting in the direction of the starting position of the sealing strip on the one hand and the jacket of the
  • the screw cap ensures that the sealing strip is in contact with the container mouth in the closed state.
  • the screw cap according to the invention with the characterizing features of claim 1 has the advantage that when the cap is placed on the container, the sealing strip is not only folded and compressed, but pulled apart and stretched around the mouth region. Tensioning is achieved in that the sealing strip is attached to the cap at one end and the other end with the bead-like thickening between the mouth region of the container and a sealing ring bead on the
  • Screw cap is jammed.
  • the bead-like thickening lies on the end face of the sealing ring bead facing away from the cap base. Since the distance between the outside of the sealing ring bead and the inside of the mouth area is smaller than the diameter of the bead-like Thickening of the sealing strip, the bead-like thickening is prevented from penetrating between the sealing ring bead and the inside of the mouth area. As a result, the weather strip is stretched.
  • the elastic deformation of the sealing strip when the container is closed with the screw cap thus causes not only a change in position of the sealing strip, but also a plastic deformation of the same.
  • the sealing strip is applied to the outside, the front and the inside of the mouth area of the container. The seal is thus better in the screw cap according to the invention than in the screw caps known from the prior art.
  • the end of the sealing strip facing the cap bottom runs in the axial direction of the screw cap. This ensures that the sealing strip is deflected when the cap is placed on the container and thereby lies against the outside of the mouth area.
  • the sealing strip extends in the direction facing away from the cap base at least up to the thread turn closest to the cap base.
  • the diameter at the end facing away from the cap bottom is smaller than at the end facing the cap bottom.
  • the length of the sealing strip in the axial direction is necessary from all sides for contacting the mouth area.
  • the change in diameter from one end to the other ensures that the bulge-like thickening of the sealing strip opens up when the cap is put on the container is placed on the inside of the mouth area and is clamped between the inside and the sealing ring bead.
  • the diameter of the sealing strip at the end facing away from the cap base corresponds approximately to the outside diameter of the sealing ring bead.
  • the sealing strip has a high elasticity. This is achieved on the one hand by the material and on the other hand by a small thickness of the sealing strip.
  • Polypropylene or polyethylene, for example, are suitable as materials.
  • the bead-like thickening has a round cross section. It thus corresponds to an O-ring. This has the advantage over a gasket with an angular cross-section that it fits optimally on the two parts to be sealed against one another and fills the available space.
  • a lip is provided on the end of the bead-like thickening of the sealing strip facing away from the cap bottom, which lip extends in the axial direction of the screw cap. This ensures an exact positioning of the bead-like thickening on the inside of the mouth region of the container when the cap is placed on the container along the entire circumference of the bead-like thickening.
  • the lip protrudes into the interior of the mouth region along its entire circumference as the cap approaches the container.
  • the outer diameter of the lip is smaller than the inner diameter of the mouth area.
  • sealing shoulders are provided on the cap base. These provide an additional seal between the
  • FIG. 1 screw cap in cross section
  • Figure 2 Screw cap from Figure 1 in cross section in a state placed on the container.
  • FIG. 1 shows a screw cap with a cap base 1 covering the opening of a container which can be seen in FIG. 2 and a jacket 2 with an internal thread 3.
  • a sealing strip 4 is attached to the cap base at an angle ⁇ relative to the cap base. The angle is something less than 90 °.
  • the sealing strip 4 has a bead-like thickening 5 at the end facing away from the cap base 1.
  • a sealing ring bead 6 is arranged on the cap base 1. The sealing strip 4 and the sealing ring bead 6 are coaxial to the axis of the
  • Screw cap provided.
  • the diameter of the sealing strip 4 changes in the axial direction.
  • the end of the sealing strip 4 fastened in the transition region between the cap base 1 and the casing 2 has a larger diameter, so that this region can lie against the outside of the mouth region.
  • the end with the bulge-like thickening 5 has a smaller diameter and can therefore lie against the inside of the mouth region of the container.
  • the area between these two ends lies in the state placed on the container on the front side of the container.
  • a sealing shoulder 7 is arranged on the cap base concentrically with the sealing ring bead 6 and the sealing strip 4. Their diameter is smaller than the diameter of the sealing ring bead 6 and the sealing strip 4.
  • FIG. 2 shows the screw cap from FIG. 1 in a state screwed onto the mouth area 8 of a container 9.
  • the sealing strip 4 is deflected through the mouth region at the end facing the cap base 1 in the direction of the cap base 1 and lies against the outside and the front side of the mouth region.
  • the bead-like thickening 5 is pressed down by the sealing ring bead 6. This results in a plastic deformation of the bead-like thickening 5.
  • the section of the sealing strip 4 facing away from the cap base 1 lies against the inside of the mouth area 8.
  • the length of the sealing strip is just so great that it can be applied to the mouth region 8 by plastic deformation.
  • the deformation is not limited by the cap base 1. In Figure 2 it can be seen that a cavity remains between the cap base 1 and the deformed sealing strip 4.
  • the deformation of the sealing strip 4 provides an ideal seal between the mouth area 8 and the screw cap.
