Abstract: A paper-industry article for making an outer skeleton (3) of a container (2) which also includes an inner layer (9) of thermoplastic material and which has a bottom wall (6), a plurality of lateral walls (5) and an annular perimetric flange (4), the outer skeleton (3) extending at the perimetric flange (4), at the lateral walls (5), at the bottom wall (6), wherein the paper-industry article (1) includes a continuous annular frame (7) intended to constitute the outer skeleton (3) of the container (2) at the perimetric flange (4) of the container (2), and a plurality of wings (10) which extend starting from the continuous annular frame (7), each of the wings (10) being intended to constitute the outer skeleton (3) at one of the lateral walls (5) of the container (2), and at least one of the wings (10) also being intended to constitute the outer skeleton (3) also at the bottom wall (6) of the container (2).

Abstract: A paperboard article (1) for making a container (8) comprises an annular frame (2), which surrounds an internal zone (20), and a plurality of wings (3) connected to the annular frame (2). Each wing (3) comprises a first portion (31) and a second portion (32), wherein the second portion (32) is connected to the annular frame (2) and is interposed between the annular frame (2) and the first portion (31). The paperboard article (1) is configured to adopt a flat configuration and an expanded configuration. In the flat configuration, the paperboard article (1) has a substantially planar shape and the wings (3) are coplanar without overlapping each other. In the expanded configuration, the paperboard article (1) has a substantially tray-like shape, wherein the annular frame (2) forms an annular flange (71), the first portions (31) of the wings (3) form a bottom wall (72) and the second portions (32) of the wings (3) form lateral walls (73).
