The invention relates to a blank for assembling polyhedra, comprising at least three edges (2a, 2b). Each of the edges (2a, 2b) comprises: a first tongue (4) that extends beyond the edge (2a, 2b) and forms a folding line, at least two closure slots (12) provided on each edge (2a, 2b), a second fold-down tongue (6) that extends beyond the first tongue (4) and forms at least one fold-down line (30), a closure tab (10) that extends beyond the second tongue (6) and is aligned with a closure slot (12), and a third tongue (8) which extends beyond one of the lateral edges (22) of the first tongue (4) and which can be folded in relation to the first tongue (4) in order to engage with the adjacent edge (2b). The invention also relates to a polyhedron formed from the blanks of the invention, as well as to an assembly method. |
