  • the invention relates to a container with a tight stopper before opening, such a container containing a content, and, finally, a method of packaging such content.
  • a container with a tight closure before opening comprising a container such as a plastic bottle having a neck defining an opening and a closure system associated with the neck of the container and ensuring its tight closure before the first opening.
  • plugs of the type comprising a base and a movable or removable cap, the base being provided with a tearable lid associated with a ring.
  • the caps of this type are fixed essentially by clipping on the neck of the container or the edge of the opening which they delimit.
  • the container is metallic while the cap is made of plastic, which causes real discomfort for recycling.
  • the closure system comprises a seal in heat-sealed aluminum on the neck of the container and a plastic capsule allowing the closure of the container after the first opening.
  • Such an embodiment has a number of drawbacks.
  • the bottle can be filled immediately or several days after its manufacture, this results in dimensional constraints for obtaining a satisfactory seal between the bottle and the stopper.
  • Opening the container is difficult and requires the use of a sharp tool to pierce the aluminum seal.
  • Sealing after the first opening cannot be guaranteed. It depends on the quality of the heat-sealing and the tearing of the aluminum seal during the first opening.
  • the payment of the contents of the container depends on the quality of the tearing of the cover.
  • the invention aims to remedy these drawbacks by proposing a container of the type previously mentioned in which the closure system is single-material and captive.
  • the contents of the container are poured regularly.
  • the opening and the filling of the container are easy and seal even after the first opening.
  • the material of the stopper is identical or compatible with that of the bottle, which facilitates recycling.
  • the container can be closed on the packaging line in a single operation.
  • the invention relates to a container with sealed closure before opening of the type comprising a container such as a bottle having a neck defining an opening, a closure system associated with the neck of the container and ensuring its closure. sealed before the first opening, characterized in that the closure system is a plastic stopper comprising a base and a cap, the base being rigidly fixed to the neck of the container by sealed welding at the place where two walls respectively of the neck and base are applied against each other; the base comprising, during manufacture, a tear-off cover which, before tearing, ensures a tight closure and, after tearing, forms an opening allowing the contents of the container to be poured; the cap being associated with the base while protecting the cover or the opening which it forms after tearing, the cap being mobile or removable relative to the base, so that the seal before opening is provided by sealed welding and the seal before tearing.
  • the closure system is a plastic stopper comprising a base and a cap, the base being rigidly fixed to the neck of the container by sealed welding at the place where two walls respectively
  • the stopper also comprises means for inviolability of the cap; the welding extends along one or more peripherally continuous lines so as to provide one or more sealing barriers. The welding extends along one or more lines located on one or more different walls of the neck and the plug.
