  • Patent number: 4998622
    Abstract: A plastic pail (23) and a plastic lid (22) are constructed at their rims so that the lid securely seals and catches in. Pockets to receive a carrying handle are part of a cylindrical ring (28) which surrounds the pail wall concentrically. This ring is drawn down arcuately at two diametrically opposite points (25), so that it is possible to grip and remove the lid (23) there, and a circular alignment of pails stacked nested without lids is simultaneously possible by this means.In a particular construction the recesses formed by the arcuately down-drawn parts of the ring are covered by tear-off bridges (40) which are fastened to the ring radially outside the latter.
