A dual-chambered container includes a chamber which contains, for example, a dry drug and a chamber which contains, for example, a medical liquid. The chambers are defined in first and second bags, with each bag having a weak seal formed in a side thereof. The bags are formed separately and then joined to one another so that the weak seals therein are positioned so that a passageway is formed between the bags when the weak seals are forcibly broken. The chambers can be sterilized independently of each other and, consequently, the container can be manufactured in a manner which minimizes the amount of labor required.

[ What is claimed is:] [1.] A dual-chambered container comprising:a first bag having a chamber therein, and having a weak seal formed in an end thereof, said first bag comprising two plastic sheets bonded to one another to form said chamber therein, and said weak seal in said first bag comprising a weak-sealing member sandwiched between said plastic sheets at said end thereof, said weak-sealing member being fusion bonded to said plastic sheets so that portions of said plastic sheets form ears that are not joined to one another and an end of the weak-sealing member is exposed between said ears to form a tongue; anda second bag having a chamber therein, and having a weak seal formed in an end thereof and being joined to said first bag, said second bag comprising one of a cylindrical plastic sheet and a pair of plastic sheets having opposing edges bonded to one another to form said chamber therein, and said weak seal in said second bag comprising a weak-sealing member disposed in said end of said second bag, said weak-sealing member being fusion bonded to said end so that a portion of said weak-sealing member protrudes from said end to form a tongue;said weak seals in said first and second bags being positioned such that the weak-sealing member of said second bag is inserted in and between the ears of said first bag such that the tongues of said bags are in juxtaposition and the ends of the bags are bonded together such that a complete and continuous weak seal extends between the two bags and forms a passageway when said continuous weak seal is broken,wherein said weak-sealing member in each of said first and second bags is a sheet piece of a polymer blend comprised of at least two polymers, one of said polymers comprising the first and second bags and having a limited affinity to the other polymer or polymers in the blend and wherein one chamber contains a dry drug and the other chamber contains a medical liquid.
