WIPO Patent Application WO2004043800
Kind Code:

Abstract:
A container comprising a bowl (11), and a lid (12) for closing the bowl, the periphery of the bowl and the lid being arranged to be non-releasably interconnected, and, said lid or said bowl having a frangible boundary region (31) adjacent to its periphery, whereby at least a major portion of the lid (12) can be detached from the periphery of the container to open the container. There is also disclosed a method of producing a frangible boundary region (31) in a container lid (12), and an apparatus for performing the method, the method comprising supporting that region of the lid which is to contain the frangible boundary, on an anvil (37) the surface of which has a plurality of spaced recesses (39), and cutting said material by means of a blade (41) having a planar edge (42) parallel to the plane of the top surface of said anvil so that the blade cuts through the lid material completely where the lid material is supported on the anvil, and the material of the lid aligned with said recesses is flexed into said recesses by the blade, the depth of said recesses below the top surface of the anvil being less than the thickness of the lid material so that the lid material above said recesses is cut into and so thinned, but is not cut completely through, by said blade.
