Abstract
A plastic bucket, bin or cup type package has inner and outer mouth flanges (4, 6) forming an annular groove (12) for receiving the downward rim flange (20) of a pressure lid such that an outward round locking nose on the flange outer side is in holding engagement with inward holding nose (14) on the outer container flange. The rim is of V- or U-shaped cross-section to form inner and outer rim flanges (22, 26) one having a gripping member (36) to facilitate upward drawing of the lid. The member is associated with a local area of the rim flange such that this flange can be forced inwardly by the member to release its locking engagement with the outer container flange and then be drawn upwardly to release the lid. The member pref. projects outwardly over the edge of the outer container flange or upwardly from the edge of the outer rim flange. The plastics is e.g. polyethylene.
