Abstract
The present invention relates to a pressurized package and a method for manufacturing and filling a pressurized package. The pressurized package has an outer container () and an inner container () situated within the outer container (). In the outer container () a chamber () for material () to be dispensed is arranged and in the inner container () a propellant chamber () for propellant () is arranged, which are separated from each other in a manner that is impermeable to liquid and gas. The outer container () is closed by a cover part () on which a valve part () is arranged for dispensing the material () from the chamber () outwards. To improve pressurized packages of this type, a pressurized cartridge () containing a propellant () is arranged in the inner container (), and the pressurized cartridge is associated with an opening mechanism () for at least one-time opening of the pressurized cartridge () to the propellant chamber () of the inner container (). The opening mechanism () reacts to filling of the chamber () with material () to be dispensed.
