ABSTRACT:
A rigid rectangular cheese mold includes a bottom and four upright walls heatsealed to each other at their edges. The walls are provided with outwardly diverging drainage slits during injection molding of the walls. The drainage slits form rows extending in the longitudinal direction of the walls, the drainage slits of one row are staggered with respect to the slits of the other row. The outer side of the cheese mold may be reinforced by reinforcing strips or a reinforcing strip-like frame. The inner surface of the wall has whey discharge recesses formed in a net structure comprising first structure ribs and second structure ribs. The first ribs extending in the vertical direction of the wall are thicker than the second ribs extending in the horizontal direction. Additional channels on the inner side of wall may connect the whey discharge recesses. The net structure is also formed during injection moulding of the walls.
