<p><P>PROBLEM TO BE SOLVED: To provide a method of reusing small gas containers by efficiently collecting the small gas containers and by precisely deciding the possibility of reusing the collected containers to achieve the reuse. <P>SOLUTION: A filled container is used. The used container is collected by a customer 14 via a shop 16. Inspection for deciding the pass/fail of the reuse is performed for the collected container. In the course of repeating the reuse of the used container in accordance with the result of the inspection, the serial number of the container, the empty weight, and a matrix type two-dimensional code are laser engraved on an outer surface of an unused container in advance, and the empty weight and the number of filling times are recorded as data in a container management device 12 in association with the serial number and the two-dimensional code. In the inspection of the pass/fail of the reuse of the used container, the two-dimensional code is read to read the data from the container management device, and the used container reaching a predetermined number of times is excluded so as not to be reused, and gas is filled into the used container not reaching the predetermined number of times. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
