Abstract
A pressure-assisted liquid delivery system comprises a flexible reservoir having an exit port and demand valve, a pair of substantially rigid plates for sandwiching the reservoir, and a plurality of loops of elastic rope for compressing the plates around and pressurizing the reservoir such that liquid contents thereof are expelled through the valve when it is opened without application of a suction force.
