PROBLEM TO BE SOLVED: To solve various problems with respect to packaging waste to be generated after unpacking of a package to take out a packaged product so as to save resources. SOLUTION: A reusable returnable package is capable of reusing comprises an upper package 7 covering the upper part of a product and a lower package 8 covering the lower part of the product, both of which are made by forming a synthetic resin into a tray-shape having the same shape each other. A locking projection 91 and a locking hole 92 are formed at the four corners of flanges 721 and 821 of a peripheral wall 72 and 82 in an alternate arrangement. After unpacking of the product, the packaging waste is put in the inside of the lower package and the lower package is capped with the upper package so that a pair of the package is unified by locking the locking projection and locking hole opposing to each other up and down. The unified package is brought back to a factory where the packaging waste is discarded and the pair of package is reused. COPYRIGHT: (C)2004,JPO
