Abstract:
1. Process of manufacturing a double-skinned inflatable bottle blank which comprises: (i) stacking two sheets of liquid impermeable, flexible foil material; (ii) blanking the sheets to create respective, shape-congruent blanks having each a contoured perimeter edge; (iii) bonding the two blanks along joining seams that follow the contoured perimeter edges, but for at one or more inflation locations, thereby to define a double skinned blank into which an inflating fluid can be introduced through the inflation location; (iv) additionally bonding the two blanks at a plurality of discrete stiffening seams which are arranged in a predetermined grid thereby defining a grid-work of intersecting, inflatable stiffener structures in at least such part of the double skinned blank which will provide an upstanding peripheral wall of the bottle when erected through inflation; (v) folding the double skinned blank and (vi) selectively bonding together portions of the joined perimeter edge of the double skinned blank, but for at a predetermined filling/dispensing location, to define a double-skinned, inflatable bottle blank with an internal cavity surrounded by a bottom wall for standing the bottle upright, said peripheral wall and a top wall, the filling/dispensing location located in the top wall to define a dispensing orifice for filling and dispensing liquid into and from the internal cavity, the inflatable stiffener structures providing an exo-skeleton about the internal cavity when inflated.
