TANK Russian patent published in 2019 - IPC B65D8/08 B05C11/11 

FIELD: package and storage.

SUBSTANCE: invention relates to a container having a rectangular contour in the cross-section, the housing of which is made by connection of two rigid components and is characterized by the structure of walls containing reinforcing and hardening elements. Tank is made in the form of hollow parallelepiped with base 1, two identical larger side faces 2, 3 and 4, 5 and two identical smaller side faces 6 and 7. Wherein tank comprises girder frame including two three-layer side members 8 and 9 made of metal, each of which comprises rigidly connected flat parallel layers (10, 11, 12 and 13, 14, 15, respectively) and cross bars 16. Side faces of parallelepiped of tank are formed by two identical channel boxes 17 and 18, each of which has profile in cross section. Free ribs of U-shelves (i.e. free ribs of half-borders 2, 3, 4, 5) are made with transverse bends 10, 12, 13, 15 oriented outward and forming extreme flat elements of side member 8 (i.e. its extreme flat elements 10 and 12) and side member 9 (i.e. its extreme flat elements 13 and 15). Extreme flat elements 10, 12 and middle flat element 11 are rigidly connected to form three-layer side member 8. Extreme flat elements 13, 15 and middle flat element 14 are rigidly connected to form three-layer side member 9. Medium flat elements 11 and 14 of frame side members are rigidly connected with crossbars 16 thus forming girder frame with three-layer side members 8, 9 and crossbars 16. Said side members have a threefold function: they connect channel channels 17 and 18 to form tank parallelepiped; they are reinforced (due to three-layer structure) axial stiffness ribs of tank, thus increasing spatial stiffness of tank; they are the side members of the spar frame, keeping in certain points of the internal volume of the tank cross bars 16, which guarantee the limiting deformation of the larger side faces of the parallelepiped of the tank under the action of the weight filling the tank.

EFFECT: technical effect consists in creating effect of power frame retaining larger edges of tank against deformations under action of weight of liquid in tank.
