Abstract
Abstract A portable water carrier and dispenser comprising a pillow-shaped enclosure of strong, lightweight, flexible material; a reservoir, similarly shaped, of impermeable material, adapted to receive and retain water disposed within the enclosure; a conduit for establishing fluid communication with the reservoir interior; and shoulder straps and waistbelt attached to the enclosure to allow a user to carry the dispenser on his back. The volumetric dimensions of the reservoir are slightly greater than those of the enclosure to allow the enclosure to provide bottom and side support for the reservoir when containing water. One end of the conduit is interior the reservoir, and secured to the bottom corner thereof. The other bottom corner of the reservoir is held in place within the enclosure when the reservoir is empty by a special clamp provided for this purpose. A plurality of apertures are provided proximate the interior end of the conduit and near the reservoir bottom to allow water to flow freely into and out of the reservoir. This flow is controlled by a double shutoff Wye valve at the exterior end of the conduit. A protected elastic seal binds the opening of the reservoir to the tubing at the top of the enclosure. A locking drawcord system is used to shape the enclosure as desired for transport.
