The bottle or glass presentation box is made from a cardboard or polymer blank which has two main panels (3,5) and two junction panels (2,4). Each junction panel comprises a sloping folding line (12-15) so that a triangular portion (t1,t2) can be formed delimited by the corner of the panel and the sloping lines. The triangular portions are folded down inside the box at right angles to the main panel to provide a curved shape with inwardly turned cavity.
