Abstract
A container (1) made of flexible material (2) is, suitable for either vacuum-packed or nonvacuum-packed products and/or sterilizable products, or for containing liquid products, having stiffening plates as a cover (3) and as a base plate (4) and a system of folds which involves a horizontal folding edge (22) and two opposed vertical folding edges (23). In a first embodiment, the cover plate (3) has a lid (6), for example opening on a hinge, and the base plate (4) contains an expansion chamber (21), which communicates with the outside in order to compensate for any possible variation in the volume of the product inside the container (1), at the moment of packing. In another embodiment of the container (1), the cover plate (3) is provided with a dispenser spout (25), and the base plate is joined to the cover (3), in such a way as to allow the containers (1) to be stacked on top of each other, being used inside the plates (3, 4), which hold the plates (3,4) together after the axial crushing of the empty container.
