Abstract

In a method to produce a container having an inside bag for the accommodation of a filling material which is applied by a propellant between the container and the inside bag from a valve or the like, 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 to be placed in an oven and, there, to be rotated for a lengthy period.
