ABSTRACT:
In a cardboard container, having a bottom wall and side walls, slits are defined to extend only in the bottom wall and the material of the bottom wall is deformed or bent so that the portions of the bottom wall, adjacent to the edges of each given slit, are situated different planes and are maintained in these different planes by means of a sheet of synthetic material. The sheet of synthetic material is shaped by heat deformation to conform with the deformed shape of the bottom wall.
