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.

Abstract: A multiple chamber container includes a first sheet; a second sheet; a first peel seal between the first and second sheets, the first peel seal extending across the first and second sheets; wherein at a first time at least one strong seal is provided around a periphery of the first and second sheets so as to leave an opening between the first and second sheets, and wherein a second peel seal is provided between the first and second sheets, the second peel seal extending across the opening between the first and second sheets; and wherein at a second time the second peel seal is removed and the at least one strong seal is extended to seal the opening between the first and second sheets.

Abstract: A laser device is provided for performing an annular circumferential welding on a workpiece, and includes a laser head having a laser source configured for emitting a laser beam to perform welding around an outer circumferential target area of the workpiece. Also included is an optical reflector assembly having at least two optical reflectors spaced from the workpiece for reflecting the laser beam emitted from the laser head. The reflectors are spaced from each other, disposed on opposite lateral sides of the workpiece, and inclined relative to an axis transverse to a longitudinal axis of the workpiece so that the circumferential weld is achieved by a single cycle of the laser beam.
