Abstract
Abstract A container has an integral wall defining a moat or channel around its top edge and a lid that seals both with the rim of the container and the upper edge of the moat. The seal can be a plug-type seal, a telescope-type seal or a rim-seal where the rim of the container and/or the upper edge of the moat are held between integral upstanding walls on the rim. Combinations of two different types of seal may be used.
