Abstract
Abstract The container comprises a plastic box, an inner, reusable lid and an outer lid. The box has an inner flange against which a peripheral flange of the inner lid bears, and an outer flange to which the outer lid is welded. A pocket can be located between the inner and outer flanges of the box opposite a region of the edge of the inner lid to permit the introduction of a flat implement under said edge for lifting the inner lid. And/or the outer lid can be welded not only to the outer flange of the box but also to the periphery of the inner lid.
