<p><P>PROBLEM TO BE SOLVED: To provide a packing container having excellent stab resistance while maintaining container strength (buckling strength) to an existing state without increasing the thickness/weight of the existing side wall. <P>SOLUTION: The packing container is composed of an aluminum alloy comprising, by mass, 0.70 to 1.10% Mn, 1.00 to 1.70% Mg, 0.10 to 0.30% Si, 0.30 to 0.60% Fe and 0.10 to 0.40% Cu, and the balance Al with inevitable impurities, and, in which the metal thickness of the side wall is 0.095 to 0.115 mm. The tensile strength in the axial direction of the side wall is≥290 MPa, and also, when internal pressure of 200 kPa is applied to the inside of the packing container and a needle with a tip radius of 0.5 mm is stuck into the side wall, the displacement in the side wall till its penetration is≥1.9 mm. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
