PURPOSE:To ensure safety and to enable efficient recycling by drawing out an inner bottle from an outer bottle at every recovery from a market to wash the same and using a new preform in the outer bottle to perform biaxial stretching blow. CONSTITUTION:A bottle 20 being a completed product obtained by biaxial stretching blow molding is a double-wall bottle equipped with an outer bottle 22 and an inner bottle 24. The inner bottle 24 of the double-wall bottle 24 recovered from a market is drawn out of the outer bottle 22 and the outer bottle 22 among the mutually separated inner and outer bottles is washed in a washing process. The recovered outer bottle 22 or a newly molded outer bottle 22 is subjected to biaxial stretching blow molding by a molding apparatus 10 to become the outer bottle 22 of the double-wall bottle 20. In this case, as the inner bottle 24, the preform newly subjected to injection molding by the molding apparatus 10 is used. |
