Title:

SHAPE-MAINTAINING LIFT-TYPE CUBOID BAG WITH MULTISTAGE CONFIGURATION

Document Type and Number:

WIPO Patent Application WO/2020/021703

Kind Code:

A1

Abstract:

A shape-maintaining lift-type cuboid bag is characterized by comprising: a cuboid bag that is a bag with a substantially cuboid shape to accommodate objects to be accommodated in the internal space; a bottom face holding mechanism that holds the bottom face by applying a tensile force; a side face holding mechanism that holds the side faces by applying a tensile force; a central hanging body that extends in the vertical direction with one end thereof fixed to the center of the bottom face of the cuboid bag and that holds the bottom face holding mechanism and the side face holding mechanism at an intermediate position in the vertical direction; and a ring shaped hook holding unit into which a hook is fit and that is connected to the other end of the central hanging body. Thus, it is possible to provide a cuboid bag that has minimal deformation when being lifted in the vertical direction, that has stable strength even with a bag with a height such that the height to width ratio exceeds 1:1, for example, in which soil particles are compacted in stages in the height direction, and that does not tear even with a height with a small aspect ratio.
