FIELD: packaging industry.SUBSTANCE: invention relates to containers for storing liquids, and a set of these containers can be used for carrying out different, including industrial, technological operations involving liquids. The container for liquid comprises an inner container 1 of a thin material with a branch pipe 2 for connecting pipe fitting. The inner container 1 is located in the outer casing, which is made demountable from four metal grids 3 provided with a stand 4 in the lower part. The outer casing is provided with means 5 for creating the preliminary compression stresses in the material of the inner container 1. The inner container 1 is composed of two parts: the upper part 6 is made in the form of a truncated four-sided pyramid with a descending angle of slope in a range of 2°-6° to its lower part 7, which is made in the form of a quadrilateral pyramid and is mounted on the stand 8 of the metal grid. The stands 4 and 8 are arranged so that the distribution of load on them from the inner container 1 is close to uniformly distributed. Each of the four grids 3 is adjacent to the corresponding side of the inner container 1 so that, the grid size in each horizontal section is smaller than the size of the inner container 1 by 2-10 mm. Means 5 for creation of preliminary stresses can be made in the form of clamps located on the lateral edges of the grids 3, at that the force from the screw of each clamp is directed along the line close to perpendicular to the lateral faces of adjacent grids 3. The clamp can be made in the form of a single unit and comprises two screws mounted perpendicular to each other.EFFECT: development of container for storing liquids.3 cl, 4 dwg |
