  • Patent number: 8714394
    Abstract: A storage container set comprises multiple plastic lid elements (20, 30) and a common container element (10), the side wall (11) of which has outward-protruding locking projections (12) that have a downward-extending locking profiled section (14) at their outer ends and are provided for locking the alternatively placeable lid elements. The first lid element (30) has hinged locking clips (31) for gripping the locking projections. The second lid element (20) has a continuous peripheral edge profile (21) and a vertical profiled section (22) which embraces the locking projections (12) from outside when the second lid element (20) is placed on the container element. A profiled tongue (23) at the end of the vertical profiled section (22) resiliently engages with the locking projections (12) while temporarily and peripherally tensioning the profiled section (22).
