Definitions

  • the present invention relates to a screw cap intended to be mounted by screwing to close (or seal) the neck of a container intended to contain in particular an effervescent liquid.
  • the stopper is intended to remain attached to the container after the neck has been opened.
  • a friction cap intended to be attached to its container after opening the neck of the container is already known.

However, this friction cap does not have the advantages of a screw cap which makes it possible to close the neck of a container securely.
  • bottling lines that are configured to mount screw caps on their containers require sometimes complex and costly adaptation to adapt the bottling line to these friction caps.
  • screw caps may have different characteristics, such as an unscrewing angle, depending on the liquid contained in the container that the cap closes.
  • the unscrewing angle corresponds to an angle of rotation necessary for a cap to go from a completely screwed position to a completely unscrewed position.
