  • container closures or closure lid are used to seal the container in the closed position of the closure lid or upon rotation of the closure lid in the opening direction before the final release or removal of the closure lid from the container neck a pressure relief due to still existing internal container pressure reach, so that a pressurized lifting the cap can be avoided with the risk of scalding spurting hot cooling water.
  • Object of the present invention is therefore to provide a closure cap for the container neck of a container closure and a container closure of the type mentioned in such a way that from the outset the phenomenon of so-called champagne cork effect is avoided by radial lifting of the sealing ring from the groove base us so a pressure relief of the container interior is reached before reaching the open position of the closure lid.
  • the features specified in claim 1 and in a container closure are provided with a closure lid for the container neck of a container closure.
  • the sealing ring of the sealing surface of the Socket comes free and enters the nozzle extension, the sealing ring can escape either by acting in the container interior overpressure in certain areas of its ring circumference in the axial direction, so that the sealing ring deforms axially asymmetric, or is already deformed in the axial direction due to the design of the Ringnutbegrenzung , And thus at these peripheral areas rather reaches the area of the nozzle extension and thus partially and prematurely releases a vent path.
  • This axial deformation or deformation of the sealing ring not only requires a Vorentlcommunungsweg but also avoids lifting the sealing ring from the groove bottom of the annular groove radially outwards, so that the phenomenon of champagne cork effect can not even arise. In this way, a total pressure equalization can be achieved even at relatively high internal container pressure before the cap has reached its full open position.
  • the features specified in claim 2 are provided, whereby the sealing ring a corresponding deformed mounting position is already specified. This leads to the further advantage of a reduced frictional resistance when screwing and loosening the cap on or from the container neck.
  • the features specified in claim 3 are provided.
  • the support ribs according to the features of claim 4 and / or 5 and / or 6 can be arranged or configured.
  • the support ribs cause in normal operation a linear support of the sealing ring within the annular groove and can either fix the sealing ring deformed or allow for overpressure in the container interior during the Abschraubterrorism the closure lid sufficient axial movement of the sealing ring between adjacent support ribs.
  • a further embodiment results according to the features of claim 10 and in an embodiment optionally according to the features of claim 11 and / or 12.
