The flap-top packet consists of a box-part (10) and lid (11) attached to the rear wall (12) of the box. A collar (28) consists of a front wall (29) and sides (30,31). A bottom lid-closure edge (34) and a front box wall (15) are defined by a counter-closure edge (35). The straight lid closure edge is especially across the upright packet-edges (36), The counter closure edge is variously spaced apart along the packet's width At least one of the closure edges is corrugated, zigzag shaped or V shaped. |
