摘要：A flexible bag (104) is positioned in a rigid container (106), such as a fifty-fivegallon drum, and the bag is filled through its spout with flowable product, such astomato paste. The bag is then expanded in the container to be substantially rigid andthereby reduce film movement and resultant flex cracking. One way that the bag can beexpanded, pursuant to this invention, is for a lid (132) to be sealed onto the container anda vacuum drawn from between the bag and the container. Gas volume needs to bepresent in the bag before the vacuum is applied so that the gas in the bag can expandfrom the vacuum on its outside. Another way to expand the bag is, after filling the bagwith the flowable product, to inject pressurized gas into the bag. For this embodiment,the container need not be vacuum sealable. For example, the container may be formedfrom a metal, plastic, cardboard and the like, and the container walls can be either solidor have openings. The pressurized gas can be applied before the lid is placed on thecontainer or after it is clamp-sealed onto the container. If it is after (for example througha valve (120) in the bag fitment, the valve extending out through the lid), then thecontainer or lid preferably has a relief valve to allow the air in the closed container to

escape as the pressurized gas in introduced into the bag. The bag can have volumesslightly smaller or larger than that of the container.
