Abstract
When a packaging container is formed by sealing an area of sheet material to the edge of another area of sheet material, the L-joint or T-joint so formed is sometimes liable to rupture when subjected to blows or strain. According to this invention that danger is reduced or eliminated by moulding a zone (4) of an end closure panel (3) abutting on the container wall edge to which it is jointed so that it forms a flange resting against and bonded to the face of said wall (1). The flange may be provided with a lip (6) projecting from a short length of the edge of said closure panel.
