"CLOSURE-PERFECTED SEAL FOR PLASTIC CONTAINERS", which is characterized by being constituted by a body of any section, which forms the container itself and a lid that fits into the mouth of the same with a step that leaves its flush walls, emerging from the edge of both pieces a horizontal peripheral flap, which when closed are attached and are welded to each other, so that the opening is only possible by breaking said tabs, for which purpose they are weakened in the joint, the container can then be used in the same way as an ordinary one.
