PROBLEM TO BE SOLVED: To propose a method for economically repeatedly using various containers used for preparation of a polyurethane material. SOLUTION: The repeated use system for containers for preparing the polyurethane material comprises a repetition of a series of steps comprising a step for pasting or coating a material for forming a mold-release surface on the surface of the various containers used for preparation of the polyurethane material contacted with the polyurethane material, a step for charging/mixing the polyurethane material into the container, discharging the resultant mixture from the container and curing the polyurethane material sticking to the mold-release surface to form a film, and a step for repeatedly using the container having the polyurethane film for the purpose of preparing the polyurethane material and finally peeling the polyurethane film.
