<p>The case is formed of sheets of rigid wood fibre or stiff cardboard panels, being particularly for agricultural products. It comprises a base (B) and four sidewalls (C) locked together by triangular rings (1) fitting in notches (G) in their free edges. At the corners, the base has holes (E), with which locking protrusions on the sidewalls (602) snap into engagement, these being on the tapering lower ends (102) of corner pieces (2) fitting in the rings. These pieces protrude above the sidewalls and have, at the top, recesses (202') for the locking protrusions on a case stacked above.</p> |
