<p>The packing consists of a strip of material with elastic properties which can stretch and pull tight over the container. The end of the strip is located (A) in one corner and follows the diagonal to the opposite corner (b). The strip then follows the top horizontal edge to (C) before returning along the diagonal to the corner (D). From D it returns to (a) at the top and along the edge (ab). From (b) it goes along the diagonal to (C), then follows the path (Cd) and along the edge (da), the diagonal (aB), the diagonal (Bc), the edge (cd) and the diagonal (dA).</p> |
