<p>A recessed part 8 of a top portion 2 of a container has a ridge 11 which engages with a part 9 of a lid 3 to create a secure seal against the escape of liquids. The lid 3 is hinged to the top portion 2 by an integrally moulded live hinge 12 so that it can be folded over to introduce the lid part 9 into the recessed part 8. During closing, part of the lid 3 will move passed a bulge 13 protruding from the wall of the top portion 2 which will hold the lid temporarily in a generally closed condition. A tab 14 at the end of the lid 3 can then be grasped to pull the lid open again to snap past the bulge 13. However when it is desired to seal the container into a closed condition the lid 3 is pushed down further so that the tab 14 is turned upwardly by engagement with a side wall 15 of the top portion 2 until, ultimately, the tab 14 snaps beneath a projecting ledge 16. Once the tab 14 has snapped into position below the ledge 16 it cannot be grasped and the rest of the lid is fully received into the recessed part 8 to seal off the container. <MATH></p> |
