Abstract: In the case of a process for producing a two-chamber pressure-package (R) an inner body (2) of fold-forming, respectively crumplable, material is connected with an outer casing (1) in the area of an adhesive layer (3). Then outer casing (1), adhesive layer (3) and inner body (2) together form a bead (7) around an opening (13). However, a ring (14) is removed from the outer casing before the bead (7) is formed.

Abstract: A method for producing a container, such as for example a can or tube, for the accommodation of a filling material, wherein after production of the container, its interior is primed and wherein a coating is applied on the primer with a layer thickness of 30-70 um. A plastic, preferably made of a polyolefin or the like, is used as the coating.

Abstract: A method for producing a container having an inside bag for the accommodation of a filling material w which is applied by a propellant between the container and the inside bag from a valve or the like, wherein after production of the container, for example by pressing, deep drawing or the like, its interior is provided with an inside protective lacquer and subsequently primed. Thereupon, plastic for the inside bag is injected into the container and the container having the inside bag is subsequently subjected to heat to remove superfluous solvent from the plastic. Then a bottom hole is shaped out for the later introduction of the propellant. After injection of the plastic, the container is placed in an oven and rotated therein for a lengthy period.

Abstract: Process for producing a two-chamber pressurized package having an outer body enclosing an interior space which can be subjected to pressure and forms an opening through which an inner body of a material which can be folded or crumpled is inserted. A valve is fitted thereon and the outer and inner bodies are connected to one another in a predetermined region.
