Abstract

A multiple chamber container forming and filling method includes (i) forming at least one strong seal around a periphery of first and second sheets so as to leave an opening between the first and second sheets; (ii) forming a temporary peel seal across the opening; (iii) forming a mixing peel seal between the first and second sheets so as to separate a diluent chamber from a powdered drug chamber; (iv) adding diluent to the diluent chamber; (v) sterilizing the multiple chamber container including the diluent; (vi) opening the temporary peel seal in an aseptic environment; (vii) adding powdered drug to the powdered drug chamber through the opening; and (viii) strong sealing the opening so as to be closed.
