Abstract
Bag-in-box packaging of products which will not readily flow under gravity conditions for discharge. The bag is of special three-ply form to provide separate product and pressure chambers. Coupling fitments are connected independently to the respective chambers. When it is desired to dispense the product, the product fitment is exposed at a wall of the box along with the pressure fitment. A dispensing valve on the product fitment is opened and pressure is supplied and maintained in the pressure chamber to expand it and exert pressure through the baffle wall on the product in the product chamber to aid in the dispensing of the product therefrom. Before applying dispensing pressure, the box is disposed in an enveloping pressure-resisting unit. A novel method is provided for efficiently producing the special bag.
