ADAPTIVE FOLDING CONTAINER FOR LOAD STORAGE AND CARRYING Russian patent published in 2010 - IPC B65D21/08 

FIELD: machine building.

SUBSTANCE: invention refers to containers for storage and carrying various loads. The folding container is made in form of a bag or cover out of elastic material, consisting of interconnected four walls adjoining in an empty container, and of a bottom. Also the bag of the container is formed with four bands of material wound into cylinder rolls; the rolls are automatically unwound/wound and gradually increase/decrease volume of the bag at filling and emptying the container correspondingly. Magnet-solid tissue is used as a material of the bag; this tissue has a polymer base and filler in form of powder out of magnet-solid material magnetised in axial direction. One end of each four bands is freely wound onto one side of a flat rectangular non-magnetic frame bent out of rods of round cross section. Other free ends of the bands of formed cylinder rolls on opposite sides of the frame are connected with each other and are positioned crosswise overlapping one above the other; foldable handles are hinged at angles of the frame.

EFFECT: improved operational characteristics due to adaptation to load volume, compact in folded state and volume-accommodated in unfolded one.
