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.

A flexible container for separately storing first and second materials and selectively allowing said first and second materials to be intermixed, said container comprising: an elongate, hollow receptacle having a closed proximal end, and a closed distal end, with an interior surface and an exterior surface extending between said proximal and distal ends; a hollow member disposed in said receptacle between said proximal and distal ends, said hollow member having an external circumference which is smaller than the internal circumference of said receptacle; and removable sealing means for providing an openable, fluid-tight seal between the exterior surface of said hollow member and the interior surface of said receptacle, said seal thereby dividing said receptacle into a distal chamber containing a first material and a proximal chamber containing a second material, whereby the removal of said sealing means opens said seal to provide a passage between said proximal and distal chambers, so that said first and second materials can become intermixed.
