Abstract
A dispensing pouch comprises a pair of superimposed panels sealed together to define a reservoir, adapted to contain a high viscosity liquid therein. A spout is formed on a lower end of the pouch and has a pump disposed therein that defines a charging chamber, communicating with the reservoir, to retain a pre-measured charge of the liquid therein. The liquid is discharged from the charging chamber in response to the external application of pumping pressure onto an outer side of the spout. The pouch is adapted for mounting in a dispensing unit, having a dual-action pressure plate, for periodically pumping and dispensing the pre-measured charge of liquid from the charging chamber of the pump. The pump is preferably defined by a separate insert, sandwiched between the panels of the pouch. A method for making the pouch is also disclosed.
