ABSTRACT
A returnable container system was introduced for vegetables produced in Okinawa prefecture which was then smoothly distributed within the prefecture. The returnable container system has reduced packaging costs, labor costs, and affected the preservation of vegetables. However it has been discussed that the system in Okinawa be terminated due to its low recovery ratio, losses due to breakage and abuses in its use. Therefore, the actual distribution conditions of the contaillers were investigated, and the strength of containers with time based on dropping tests and conmpression tests were measured and reported. It was detemined from the results of the strength test that the container strength was not a serious obstacle to their practical use.HomePageKeywords: returnable container, recovely ratio, dropping test, compression test
