  • Closing system for a container, for example for trigger dispenser
    Patent number: 7980427
    Abstract: The present invention relates to a closing system for a container, comprising a neck of the container and a closing body. The body wall comprises at least one flexible tongue and at least one relatively stiff protrusion that, when the tongue is seated in the seating portion, arranges circumferentially sided to a circumferential stopping projection of the neck. In an imminent interference configuration, reached by relative rotation between the neck and the closing body, the protrusion interferes with the circumferential stopping projection for making an obstacle to the further rotation in the same direction of rotation, while the tongue is free from interferences with further obstacles to rotation.
