A bag material has a tubular shape and can be folded back at an intermediate position in a longitudinal direction. Crushed stones can be stored in a folded part of the back material. An opening on one side of the bag material can be moved to a position close to an opening on the other side of the bag material. A one-side closing rope that closes the opening on the one side of the bag material is provided near this opening. An other-side closing rope that closes the opening on the other side of the bag material is provided near this opening. The other of the one-side closing rope and the other-side closing ropes can be released with the opening closed by one closing rope.

The invention is directed to a flexible and collapsible extended-length bulk bin. The bulk bin includes two molded plastic end pieces that are connected at each side to each by metal rails. A bottom panel and two side wall panels are also positioned between the two molded plastic end pieces.

An apparatus for forming a shipping container comprises a tubular body extending between top and bottom ends, first and second bottom panels extending from the bottom end, the first and second bottom closing panels rotatable from a co-planar configuration with the tubular body to a position extending perpendicularly across the bottom of the tubular body and at least one fastener adapted to secure the bottom closing panels across the bottom end of the tubular body. The shipping container may also be formed by a planar body having top and bottom surfaces wherein the top surface is adapted to support a load, at least one pocket extending across the bottom surface and at least one spacing element sized to be received within the pocket. The apparatus may include at least one rigid body between the top and bottom surfaces of the planar body and side walls extending upwardly therefrom.
