FIELD: mechanical engineering.

SUBSTANCE: hollow lap joint for mounting of containers intended for transportation of fluids and loose materials, which containers are equipped with tray-shaped base, has internal plastic container disposed onto the base. Plastic container has plugged pour-in neck and releasing branch for connecting take-in fittings. It also has external case made in form of grinned basket or sheet case. Base has bottom for rest against internal container, corner and central feet made of sheet steel, which are disposed onto support frame or slides. Bottom of base and external case of internal container are fastened to feet. Top and/or low rods of joints are formed integrally to corner feet and are welded to central feet. The rods go ahead of corner feet or central feet correspondingly up and down. Free ends of feet are made for deformation correspondingly to closing head to fix low frame of grinned basket or lower end of sheet case and external end of sheet bottom of base at corner and central feet and for fixing corner feet and central feet onto support frame of base.

EFFECT: simplified mounting of separate parts of container.
