Abstract
A liquid material dispenser includes a rigid housing having a flexible partition defining first and second compartments on opposite sides of the partition, and an electrolytic cell in the first compartment capable of generating a gas when energized by a source of electric current in order to expand the first compartment and thereby to contract the second compartment. The second compartment contains the liquid material which is dispensed via a discharge opening in accordance with the rate of generation of the gas.
