Patent

CA 2354316

A tubular container for vacuum packaging products is provided according to the present invention that includes an overcap secured to at least one of the opposed ends of a tubular container that defines a bias member for biasing a membrane- type flexible lid inwardly towards products contained within the tubular container before a vacuum is applied. The flexible lid is maintained in a biased shape until the bias member is removed. As such, the flexible lid is sufficiently restrained during the vacuum packaging process, thus preventing the breakage of products located adjacent the flexible lid.
