Self-standing foldable container apparatuses and methods of using the same

A method of using a container apparatus comprising the steps of:

• providing a container apparatus comprising a body having a tubular configuration formed from a plurality of flexible layers and having a plurality of side walls, the body having a plurality of corners, each corner forming a vertex of the plurality of side walls thereby forming a cuboid shape, the body further having a top cover and a bottom cover thereby forming an interior space within the body, and first and second flat panel inserts within first and second pockets, respectively, within each of the plurality of side walls forming a fold line between the first and second flat panel inserts within each of the side walls, wherein the container apparatus is in a folded state;
• unfolding a first sidewall via a first fold line between the first and second panel inserts within the first sidewall;
• unfolding a second sidewall via a second fold line between the first and second panel inserts within the second sidewall;
• and
• standing the body upright with each of the sidewalls in an unfolded configuration.
