<p>The openings that defind the mouths of the box on both sides of the central transversal handle are partially occupied in the flat development of the lamina, by both laps (7-8) equal to the fronts confirmed in other strips (11-12) analogous to the fixed strips (9-10) which limit the opening next to the fronts. The strips (11-12) cited lastly fold over the fixed strips (9-10), the laps (7-8) remaining backed to the fronts. The laps (7-8) have collateral extensions (13 to 16) which are vertically placed next to the larger sides (2-3) and retain with their top edges the strips (11-12), collaborating with this some tongues (26 to 29) which are in prolongation of these strips (11-12) and which in the assembly adapt an intermediate position between the collateral extensions (13 to 16) and the larger sides (2.3.)</p> |
