<p>A composite container (10) is provided for vacuum packaging of products which is constructed, as follows. A hollow body portion (12) defines a desired shape for the container (10) and has an inside surface (13). A liner layer (30) is in superimposed position within the body portion (12) and covers the inside surface (13) for receiving the product (P) inside the liner layer (30) and the body portion (12) of the container. An elastic material (40) is positioned between the body portion (12) and the liner layer (30) for movably attaching the liner layer (30) to the body portion (12) in the superimposed position while allowing the liner layer (30) to constrict and move away from the body portion (12) by stretching of the elastic material (40) when a vacuum is formed on the product (P) packaged in the container (10) and then allowing the liner layer (30) to move back into the superimposed position within the body portion (12) of the container by retraction of the elastic material (40) when the container (10) is opened and the vacuum on the product (P) is removed. <IMAGE></p> |
