A container (11) for circular foodstuffs comprising a base (13) and a lid (15), integrally formed and interconnected by hinging means (33). The base (13) has a substantially circular bottom (19) and a peripheral wall (21). The lid (15) is circular and of corresponding size to the base (13). The lid (15) has an expansive top (27) for engaging the base (13) in juxtaposition with the top (21a) of the base wall (21). The container (11) includes fastening means (17) for positively locking the lid (13) and the base (15) together. The fastening means (17) comprises a circumferential tongue (43) and groove (45) arrangement. The tongue (43) is integrally formed with the top (21a) of the base wall (21) and the groove (45) is integrally formed with the lid (15). The groove is defined by an outer flared portion (38) and outer peripheral depending lip (41) complementary to said tongue (43). The depending lip (41) is sized and shaped to overlap and frictionally engage the outer circumferential extent of the tongue (43) when the lid (15) is brought into the closed position.
