MEDICAL MULTI-CHAMBER CONTAINER AND SHEET STRUCTURE

PROBLEM TO BE SOLVED: To provide a medical multi-chamber container which prevents fusion of inner surfaces of reservoir chambers while securing an appropriate sealing strength for a weak seal section that divides the plurality of reservoir chambers. SOLUTION: The medical multi-chamber container includes a strong seal section 3 on the circumferences of superposed thermoplastic resin sheets 2 and 2, the peelable weak seal section 4, the reservoir chambers 5 and 6 divided by the weak seal section 4, and a medicine solution communicating section provided at the strong seal section 3. Concave and convex grooves 9 extending in the longitudinal direction of the weak seal section 4 are formed substantially wholly on one side of the opposite inner surfaces of the reservoir chambers 5 and 6. The weak seal section 4 is formed by heat-sealing the opposite flat surfaces without the concave and convex grooves 9. COPYRIGHT: (C)2008,JPO&INPIT
