ABSTRACT:
A flexible container comprises a receptacle divided into two chambers by an openable, fluid-tight barrier formed between the interior surface of the receptacle and the exterior surface of a hollow member contained in the receptacle. The barrier is maintained closed by a removable sealing band applied around the exterior of the receptacle. The removal of the band allows the wall surface of the receptacle to separate from the exterior surface of the hollow member, thereby opening a passage between the two chambers. The container is manufactured by a process comprising the steps of: (a) providing a tube of resiliently-deformable material; (b) sealing a first end of the tube; (c) expanding the tube to a desired shape; (d) partially filling the expanded tube with a first material; (e) inserting an uninflated balloon into the expanded tube; (f) inflating the balloon so that its exterior surface is spaced from, and proximate to, the interior surface of the tube; (g) applying the sealing band around the exterior surface, of the tube with sufficient tightness to sealingly close the space between the balloon and the tube; (h) filling at least part of the tube between the balloon and the second tube end with a second material; and (i) sealing the second tube end.
