FIELD: packaging industry.

SUBSTANCE: tank with a variable housing configuration for transporting liquids contains a roof, a bottom, side and front folding modules with a mutual mobile connection, a removable neck, two power cylinders, dispensing and technological pipes and pressure hoses. The tank is provided with a flexible sheath placed in the internal cavity bound with the roof, the bottom and folding modules and the compressed medium supercharger attached thereto via fasteners with an actuator. Each power cylinder is movably connected with its supporting part to the lower part of the support located under the long side of the bottom in the middle thereof. The power cylinder rod is movably connected to the center of the lower side folding module. The length of the bottom equals to the sum of the length of the roof and width of the folding module, and its width is equal to the sum of the width of the roof and the width of the folding module. Side and front folding modules are made with possibility to fold towards the vertical plane passing through the sides of the tank bottom. The internal cavity of the compressed medium supercharger located opposite to the internal cavity with a rod is connected via injection hoses with an inner cavity of each power cylinder located on the side of the rod disposed therein. The internal cavity of the compresser medium supercharger, located on the side of the rod disposed therein, is connected via injection hoses with an inner cavity of each power cylinder, located opposite to the internal cavity with the rod disposed therein.

EFFECT: invention provides reliability and hermiticity under any changes of housing configuration.
