There is disclosed a container for containing a liquid such as paint, the container having a side wall and a bottom moulded in one piece from plastics material, the container being formed to co-operate with and retain a removable lid, and comprising a flexible inwardly projecting flange moulded integrally with the side wall and adjacent the top thereof, the flange being upwardly and inwardly inclined at its attachment to the side wall. Because the flange is flexible and is inclined to the side wall at its point of attachment to the side wall, the core on which the container is moulded can be withdrawn from the container past the flange, as the flange will deflect and ride over the core. The flange then springs back to its inwardly projecting position and serves to prevent liquid slopping out of the container if the container is filled with liquid on a standard filling line such as is used for metal lever-ring paint containers.
An anti-slop container for liquids, having a side wall and a bottom moulded in one piece from plastics material, the container being formed to co-operate with and retain a replaceable lid, and comprising a flange moulded integrally with the side wall and adjacent the top thereof, said flange being of single thickness, projecting inwardly to a free edge, and extending substantially entirely around the side wall, at its attachment to the side wall the flange being upwardly and inwardly inclined, the flange being substantially thinner than the side wall and being formed with slots which divide the flange into portions flexible independently of each other, whereby all said portions are simultaneously flexible outwardly towards the container wall and upwardly towards the top of the container.
