Liquid anti-filling system for e.g. bottles, has anti-filling valve operated by pressure of liquid inside bottle, and anchorage and blocking unit for setting anti-filling valve and labyrinth manipulator to neck of bottle

摘要

The system has a labyrinth manipulator for avoiding and blocking introduction of any component that can break the bottle or container. The labyrinth manipulator is arranged conforming the orifices or steps formed in discs or similar bodies superposed around a center body. The discs are arranged such that their orifices are never coincident. An anti-filling valve is operated by the pressure exerted by the liquid inside the bottle or container. An anchorage and blocking unit sets the anti-filling valve and labyrinth manipulator to the neck of the bottle or container.
