Multi-function element from a system for the filling or the storage of an article

System for the filling or the storage of an article, comprising an element (1), including a flange (2), enclosed between an outer edge (3) and an inner edge (4) substantially parallel to each other, one being far from the other by a distance smaller than or equal to the diameter d1 of a leaflet punch, the system further including a longitudinal edge (5) substantially parallel to the flange edges (3) and (4) and far from the inner edge (4) by a distance equal to or larger than the diameter d2 of a hanging mean, the flange (2) edges (3) and (4) extending from an extremity to join the longitudinal edge (5) in an internal edge (6) delimiting a full zone (7), the flange (2) having a central lobe (8), defined between a central base (9) and a central top (10), its base (9) being positioned on a central part of the inner edge (4), at a distance from the internal edge (6) larger than or equal to d2, the system being characterized in that said central lobe (8) is flexible and can take two positions:

• an unfolded position wherein it defines two dimensions:
• a distance between the top (10) of the lobe (8) and the longitudinal edge (5) smaller than d2;
• a distance between the top (10) of the lobe (8) and the external edge (6) larger than d1;
• a folded position wherein no part of the central lobe (8) protrudes from the outer edge (3) and from the inner edge (4), defining no distance larger than d1.
