Rectangular flat folding packing - has wall with folding strip whose centre forms base between large sidewalls

摘要

The lightweight rectangular packing folds flat for transport and storage, and is designed for rapid erection. Its wall includes a folding strip whose centre forms the base and is between the two large side panels, two cover flaps being provided at the strip ends if desired. The base and the large sides have on each of the strip edges a lug (4) forming the frames for the heads on folding. The two folding walls of the heads, integral with the base, are fixed to the two bottom lugs (2). Each head wall has at its edge opposite the base lug a top lug forming, with the three other lugs on a strip edge, a frame locked in plane on erecting by nails or hooks.
