Once the merchandise has been placed in its container the procedure only requires the minimum of repetitive manipulations between the packaging site and the final destination. A support frame (1) restrained on the chassis of a specific vehicle has placed and locked on it, either the packaging distribution carrier (2) or the packaging distributors themselves (3). The support frame has central male locking pieces called corner pieces (6) with a manual or controlled locking system. Specific containers (4) for organising the merchandise layout are arranged in the distribution packages. The specific containers are arranged in the package distributor in a determined order. Inventory information is provided capable of stocking the containers in given relative positions and their subsequent transfer to the final destination.
