BUDBAG FLEXIBLE CONTAINER Russian patent published in 2006 - IPC B65D88/16 B65D81/32 B65D30/00 

FIELD: transport engineering.

SUBSTANCE: invention relates to flexible containers designed for carrying different loose loads by rail, water, air and road. Proposed container has elastic cylindrical envelope with upper and lower holes load-bearing wire rope with slinging loop and unloading wire rope with loop arranged along load-bearing wire rope, both passing through envelope along its central axis. Upper support with hole to pass unloading wire rope and lower support are mounted on load-bearing wire rope. Container has also second elastic cylindrical envelope with upper and lower holes, upper and lower ring locking devices for envelopes arranged, respectively, over upper and lower supports. Second elastic envelope has radius exceeding radius of first envelope and it is arranged coaxially to first envelope. Each ring locking device consists of ring grip and lock with unloading wire rope fastener. Side vertical hole to pass unloading wire rope is made in lower support. Invention provides transportation of two-component loose materials, for instance, dry concrete mixes, without mixing them till moment of discharge.

EFFECT: reduced number of intermediate load-handling operations with container, ensuring against obtaining of mix of wrong composition and losses at operations with components.
