Definitions

  • the invention relates to a closure cap with the features the preamble of claim 1.
  • Plastic caps are used in a variety of Closing containers used.
  • a sealing insert made of a softer material on the inside of the cap base to lay. So that the outer upper edge of the to be closed Container is sufficiently sealed, it is known for example from EP 55 916, in the area of Transition between the cap bottom and the apron to provide a circumferential pressure bead, which the sealing washer presses against the edge of the container mouth. With a Such a construction gives very good sealing results.
  • closures in combination with a container can be used in which an increased over time Can build up internal pressure, can the good sealing property lead to certain problems. If the internal pressure in the Containers, for example, by heating or fermenting the Due to the good poetry, there is increased content Risk of the container bursting.
  • EP 370 272 therefore proposes to include the circumferential bead to provide segment-like interruptions. In the area of this Interruptions can push the sealing insert outwards become. Gas can escape and the internal pressure can be reduced become.
  • closure cap according to EP 370 272 has the disadvantage afflicted in the area of segmental interruption the sealing effect is not even with normal internal pressure is more optimal. There is a risk of leakage below Normal conditions.
  • this object is achieved with a closure cap with the features of the characterizing part of claim 1 solved.
  • the cap for a container is essentially from a cap bottom and a cap apron.
  • the Cap apron is provided with internal retaining elements, which with external restraint devices at the mouth of the Can be brought into engagement.
  • the cap also has a sealing washer, at least partially lies on the bottom of the cap, and against the mouth of the Container can be pressed.
  • the cap is also with a bead in the transition area between the cap base and the cap apron. The bead is used for pressing the sealing washer to the upper, outer edge of the mouth of the Container.
  • the bead is also by at least one, segmented break divided into several blocks. If the internal pressure in the container increases, the sealing washer in the Radial outward area of interruptions be, which allows a reduction in internal pressure.
  • the sealing washer can also be ring-shaped be formed.
  • the closure cap is particularly suitable for beverages containing CO 2 , fruit juices and hot fillings.
  • the cap base is on its inside with at least one radially outward running rib.
  • the rib extends radially at least via a sealing section on the inside of the Headstock.
  • a sealing section is used here and below Section of the inside of the head plate understood, by means of which the sealing washer against the mouth of the to be closed Container, in particular can be pressed against the end face is.
  • the rib on the inside of the cap base is in Viewed circumferentially adjacent to the breaks between the individual blocks of the bead for pressing the Sealing disc arranged.
  • a plurality of interruptions are preferably arranged in the bead, so that several blocks are formed. At every break at least one radial rib is advantageously radially aligned arranged. This leads to a particularly uniform Venting function. But it is also conceivable to have several radial ones Arrange ribs on each break. With several Ribs also become a ventilation channel between the ribs formed in which the sealing washer are displaced can.
  • the angular extent of the ribs is preferably smaller than that Angular extent of the interruptions selected. With that between the outer boundary line of the rib and the Recess between the blocks, additional channels for venting educated. With increased internal pressure, the sealing washer are pushed into these channels.
  • the closure cap is preferred with approximately 9 interruptions and 9 blocks and radial beads. This value corresponds to an optimal compromise between density and Venting properties.
  • the interruptions advantageously extend over one Angles of about 5 ° to 30 °.
  • a circumferential rib can be provided on the cap bottom has a smaller thickness than the radial rib.
  • a section of a closure cap 1 is perspective and shown cut open.
  • the cap 1 consists essentially of a cap base 2 and a cap apron 3.
  • the cap apron 3 comes in one transition area 7 together with the cap base 2.
  • a screw thread 4 for Attach the cap 1 to a container 20 (see Fig. 3) attached.
  • a circumferential one Bead 6 arranged in the transition area 7 .
  • the bead 6 is used to press one flexible sealing washer 5 (not shown in FIG. 1, see FIG. 3) to the mouth of the container 20.
  • the bead 6 is through segment-like interruptions 8 divided into individual blocks 9.
  • the ribs 11 Radially on the inside 10 of the cap base 2 ribs 11 arranged on the outside.
  • the ribs 11 extend radially up to approximately in the area of the interruptions 8. It is essential that the sealing ribs 11 extend at least over a sealing section 12.
  • the Sealing section is defined by that area in which a sealing washer 5 by the action of the cap bottom 10 or the sealing ribs 11 against the mouth of the container 20th can be pressed.
  • FIG. 2 the closure cap from FIG. 1 is from below shown.
  • the sealing washer 5 also not shown.
  • a variety of individual blocks 9 are in the transition area 7 between the Cap bottom 2 and the cap apron 3 arranged.
  • the single ones Blocks 9 are separated from one another by interruptions 8.
  • the ribs 11, the Blocks 9 and the interruptions 8 are even in Circumferential direction over the inside 10 of the cap base 2 distributed.
  • FIG. 3 shows a section of a closure cap according to the invention 1 in cross section.
  • the cap 1 is with the cap apron 3 on the neck of a container 20 by means of a screw thread 4 held.
  • a sealing washer 5 is in the cap 1 inserted.
  • the sealing disc 5 touches essentially the inside 10 of the cap base 2.
  • the Sealing disc 5 is by the action of the inside 10 of the Cap bottom 2 against the upper mouth of the container 10 pressed.
  • a circumferential bead 6 presses the sealing disk 5 against the upper outer edge 21 of the container mouth.
  • the circumferential bead 6 is in the transition area 7 between the Cap bottom 2 and the cap apron 3 arranged.
  • the bead 6 has interruptions 8.
  • rib 11 which extends radially from the inside to the outside intended.
  • the rib 11 presses the sealing disk 5 in a targeted manner against the upper edge of the container mouth of the container 20.
  • the rib 11 extends at least over a sealing section 12. In the sealing section 12, the sealing washer 5 pressed against the container mouth.
  • the ribs 11 lead to a pressure relief of the sealing washer 5 in the area of Interruptions 8. This creates a path for venting.
  • the gas inside the sealed with the cap 1 Container can between the individual blocks 9 escape through the interruptions 8.
  • 3 is schematic an interruption 8 is shown.
  • the blocks 9 are with dashed lines.
  • the arrow v shows the way through which the gas degradation takes place.
