FIELD: packaging industry.SUBSTANCE: in the corner (3) of the container the curved corner part (11) of the inwardly directed edge (8) of the lid (5) comprises a foldable part (12) of the skirt made with the ability to be folded in the outwardly directed position (12') so that the central part of the curved corner part (11) of the inwardly directed edge (8) of the lid (5) moves from the outwardly directed edge (6) of the upper opening (4), and the engagement between the respective edges (6, 8) diminishes in the area of the said central part. At that the foldable part (12) of the skirt is separated from the rest part of the skirt (9) by two slits or notches extending downwardly from the area located under the directed edge (8) of the lid, or by means of two grooves (22) made in the outer surface of the skirt and extending downwardly from the area on the line (16) to the lower edge of the skirt, and the grooves (22) reduce the wall thickness of the skirt, and it can be broken along the grooves for folding the foldable part.EFFECT: container made in such a manner opens easier while maintaining the sealing effect between the lid and the upper opening.10 cl, 12 dwg |
