<p>PROBLEM TO BE SOLVED: To provide a medical care vessel that withstands a high-pressure wet sterilization at a temp of not less than 120 deg.C, together with a medical solution kept therein. SOLUTION: The medical care vessel having a laminated wall structure of transparent and flexible resins is for exposure to high-pressure wet sterilization together with a medical solution kept therein. The vessel wall consists of a reinforcing resin layer offering mechanical wall strength, heatproof resin layers made over the outer and inner surfaces of the reinforcing resin layer to protect it from heat, and a transparency maintaining layer made over the inner surface of the inner heatproof resin layer. The reinforcing resin layer and transparency maintaining layer are a blend resin layer of polyethylene and polypropylene, and the heatproof resin layer is a linear polyethylene layer of a density of not less than 0.940 g/cm3.</p> |
