Zusammenfassung:	A double-walled container is formed by gas assist injection molding. Thereafter, the container is further processed by 1) inserting a gas between the container layers (14, 16), 2) injecting a colored liquid between the container layers (14, 16), 3) evacuating the void space (18) between the container layers (14, 16), or 4) pressurizing the space (18) between the container layers.
