<p>A method of producing a package of a product, which product does not include a significant amount of gas, comprising taking a shape-retaining container having a charging opening, charging the container with the product to a level which leaves a substantial headspace and, in any suitable order, (a) completely sealing the opening with a closure of stretchable material, and (b) deforming the closure inwardly onto the product to reduce the headspace and continuing the deformation, to move product adjacent the closure into the remaining headspace, until the headspace is eliminated by the continued movement of product and closure, the method being such as to form a package which is substantially gas free and substantially hydraulically solid.</p> |
