  • Patent number: 6732921
    Abstract: In the system for managing a large number of reusable multi-trip receptacles each of which is marked by a code in an identifiable manner, the multi-trip receptacles are used in a number of cycles in several local stations (20, 21, 22) separated from each other and the code is read at each cycle. Data which have been recorded in the local stations. (20, 21, 22) for the individual multi-trip receptacles are stored allocated to the read code in a central station (10), and are evaluated to establish the number of cycles or uses of each multi-trip receptacle. The age and number of uses of each multi-trip receptacle is established using the data stored in the central station (10) and when a certain age or a certain number of cycles is reached, the local stations (20, 21, 22) are informed that the relevant multi-trip receptacle is no longer to be used.
