Abstract: A fluid storage bag comprising a storage bag sealed to a collapsible quick filling and self-sealing fill tube. After partially filling the storage bag, through the fill tube, to a desired level with water or other liquid the storage bag is inverted, thereby collapsing and effectively sealing the fill tube against itself. After use, the storage bag may be re-filled, or recycled. In one example, a 4 inch wide fill tube extends at 6 inches into the storage bag, with the last 5 inches creating a funnel to a 2 inch bottom width. In other examples air or other gas may be introduced through the fill tube; and as the bag is pressurized, the fill tube collapses and seals so that the bag may serve as a flotation device, air mattress, pillow or other device.

Abstract: A hydration bag comprising a storage bag sealed to a collapsible quick filling and self-sealing fill tube, a reusable drink port connection, and a drinking tube with mouthpiece. After filling the storage bag, through the fill tube, to a desired level with water or other fluid, the storage bag is inverted, thereby collapsing and effectively sealing the fill tube against itself. Air is bled from the storage bag through the drinking tube or port. After use, the storage bag may be re-filled, or recycled. In one example, the delivery fluid delivery fittings are detachable from the storage bag and re-usable so that the storage bag and fill tube assembly is curbside recyclable. In one example, a 4 inch wide fill tube extends at 6 inches into the storage bag, with the last 5 inches creating a funnel to a 2 inch bottom width.
