Abstract

A method of filling and sealing a bi-stable container, subjected to a gaseous environment, with a product, and a container containing the product. The container has a bi-stable, unribbed bottom having a hoop member surrounding the side edges of the container and movable between a first position, in which the container bottom is moved into a stable downwardly extended position, and a second position, in which the container bottom is moved into a stable inverted domed configuration. The container bottom is placed in its stable downwardly extended position and the product is charged into the container to a level having a volume less than the container volume but equal to the filled volume with such level defining a headspace opening. The container is then placed in a vacuum environment chamber. A generally flat lid is sealed to the container and the vacuum environment is removed from the container so as to return the container to atmospheric pressure. Hoop stress of the hoop member overcomes the bending stress around said unribbed bottom such that the unribbed bottom of the container is inverted into said stable inverted domed configuration thereby forcing the product into close contact with the lid to reduce the headspace between the product and the lid, the lid remaining in its generally flat configuration.
