Abstract
A plastics container for pressurized materials, such as an aerosol container, includes an inner vessel and an outer vessel. The vessels are both necked and are in contact throughout their extent but only bonded together at the respective necks. A valve is mounted at the necks. This configuration allows a container which will not endanger the user if the outer vessel is fractured. To enable the inner vessel to vent safely after a fracture of the outer vessel, it is provided with at least one perforation formed by an orifice.
