Abstract
A multi-layered flat walled bulk storage bin or container is disclosed. The container has crushed corners and at least two opposing bevelled corners which enable the container to be folded flat with no spring back in the folded position. The container comprises a multi-layered sleeve having at least four flat sides with corners between adjacent sides, the sleeve having compressible sheet layers, preferably corrugated board layers, with crushed corners and at least two opposing corners being bevelled corners to allow the sleeve to be collapsed so fully closed corners have adjacent sides substantially parallel without additional force applied.
