Semi-rigid material e.g. cardboard, package e.g. tray, for packaging e.g. fresh dairy product, has longitudinal and transversal walls with respective breaking lines to disintegrate walls from bottom of package

摘要

The package has two longitudinal walls (2) with an incipient breaking line (5) to disintegrate the walls from the bottom of the package so that incipient breaking lines (8) permit to disintegrate stubs (4) pasted on the walls. Incipient breaking lines (6) permit to remove a central part (2a) of the walls or to turn back the part (2a) toward the exterior. Two transversal walls (3) have incipient breaking lines (7) to disintegrate the walls (3) from the bottom so that the stubs are disintegrated by the breaking lines (8), for removing the walls (3) or turn back toward the exterior.
