System for joining containers

A system for joining containers applicable to a first container (1) with doors at the front and rear thereof and a second container (2) with at least one door at the rear thereof, attached by the smaller sides, so that a resulting container (10) from coupling of first and second containers (1, 2) is obtained, characterized in that it comprises:

• four hooks (3) applicable on the four corners of the containers (1, 2) for joining both containers (1, 2);
• a plurality of sheets (4, 5) applicable on the interior edge at the rear of the first and second containers (1, 2) fixable to both and which cover an entire interior perimeter of the first and second containers (1, 2);
• a series of electronic screens (101, 201) for adjusting identification numbers of the containers (1, 2) to adjust an identification number of a resulting container (10), wherein the plurality of sheets (4, 5) have a seal (9) on the part which contacts the internal edges of both containers (1, 2) and the series of electronic screens (101, 201) are on the first and second container (1, 2), together with control units (102, 202), power sources;
• and
• a contact (103, 203) on the interior edge of each container (1, 2) which is activated with the placement of the plurality of sheets (4, 5) and indicates to a respective control unit from the control units (102, 202) the joining of first and second containers (1, 2);
• wherein the control units (102, 202) which are respectively on each of the first and second containers (1, 2) communicate with one another.
