Abstract

The sack with lateral folds has a rectangular bottom made from one or more strips of weldable sheet material, and is rectangular in plan view when folded flat, the inner folds of the front and the rear walls, between the side walls, butting against each other. Each sidewall is made from a single sheet, and joined along the edges to the front and rear walls (11, 12) and to the bottom (4), which has a weld seam running all the way round it. Side, front and rear walls are made from a single sheet. When the sack is folded flatm the sidewall is folded into triangles inside it along its diagonals.
