A method of producing a package (1), particularly for packaging products, the method including the steps of feeding a sheet material (31) to a forming die (33); deforming and cutting the sheet material (31) to obtain a hollow semifinished body (43) of revolution having at least one inlet opening (39); forming, on an edge of the semifinished body (43), two localized bends (46) on opposite sides of the opening (39) and aligned with each other along an axis (47); permanently deforming the semifinished body (43) by rotating two portions (4)(5) of the semifinished body (43), located on opposite sides of the axis (47), about the axis (47) to form an elongated body (2) in a stable, at least partly-open condition, and which may be brought manually into an unstable closed condition in which it is maintained by a releasable retaining device (13). <IMAGE> <IMAGE> <IMAGE> |
