FIELD: packaging industry.SUBSTANCE: tare boxes comprise a bottom (102), two end walls and two side walls (108a). Each of the side walls (108a) comprises the first lateral edge (118) located adjacent the first end wall, the second lateral edge (120) located adjacent the second end wall, the lower edge (124) located adjacent the bottom (102) and the upper edge (122) located at a distance from the bottom (102). Each side wall (108a) comprises a continuous stiffening element (126) extending parallel to the lateral edges (138, 120) and at least partly to the upper edge (124). The continuous stiffening element (126) comprises a stiffening part (126a, 126c, 126d) extending at least in one area between the lateral edges (118, 120) from the upper edge (122) towards the lower edge (124) and back to the upper edge (122).EFFECT: improved operational performance.10 cl, 16 dwg |
