A multiple compartment flexible package having a receiving compartment adapted to contain one or more liquid impermeable, rupturable containers, a dispensing compartment containing an absorbent material and a passageway interposed between the compartments. Upon the application of pressure to the receiving compartment, the inner liquid container is ruptured and the liquid bursting from the inner container is directed by the passageway to the absorbent material within the dispensing compartment. The liquid contents of the inner container are absorbed by the absorbent material and dispensed therefrom at a rate depending upon the application of the package. The dispensing compartment may have a portion thereof permeable to the liquid contents or may have one or more apertures in one surface thereof adjacent the absorbent material.
