Abstract: When appliances, especially electronic maintenance appliances, are despatched, the items in the transport container include documents specifically relating to them, like instructions for use, guarantee certificates, information, etc. When appliances of a given type are sent to various countries, the documents to be enclosed are usually drawn up in the language used at the destination. For logistic reasons, however, it is uneconomical to include the documents when the appliances are packed. The invention proposes the facility for subsequently inserting the correct documents for the appliances in the transport container in which the appliances have already been packed. To this end the transport container (2) has apertures (10) covered by one or more pivoting flaps (5). Where necessary, these flaps (5) may be opened and the documents slid into the transport container. If the flaps (5) are properly dimensioned, the documents are thus safely packed.
