1. A composite liquid agent package comprising a plurality of liquid agent housing portions and a binding portion, all of the plurality of liquid agent housing portions being bound together by the binding portion for integration, wherein
each of the plurality of liquid agent housing portions includes
a pouch constituted by a heat-sealable laminated film or heat-sealable laminated sheet including at least an inner layer composed of a sealant and an outer layer composed of a sheathing material, the pouch having one end section and an opposite end section which are sealed sections formed by heat-sealing ends of the heat-sealable laminated film or heat-sealable laminated sheet; and
a liquid agent held within the pouch airtightly and liquidtightly,
the one end section is sealed so that it can be opened by applying a pressing force on the liquid agent filled in the pouch,
the liquid agents held in the plurality of liquid agent housing portions are the same with or different from each other, and
at an extremity of each of the opposite end sections of the plurality of liquid agent housing portions, a part of the sealant constituting the inner layer of the heat-sealable laminated film or heat-sealable laminated sheet constituting the liquid agent housing portion is extended outwardly of an extremity of the outer layer while keeping integral with a remaining part of the sealant to form an extended-out sealant, and the extended-out sealants are fusion-bonded together and integrated thereby to form a fused sealant, which constitutes the binding portion or a main part thereof.
