PLASTIC LID FOR CONTAINERS ABSTRACT OF THE DISCLOSURE A lid for containers, usually beverage cups which may be for hot beverages or cold beverages, is provided, having a cavity adapted for seating against the bead of the container. A skirt extends downwardly from the cavity, having a number of outwardly extending projections formed in it, each of the projections having a substantially rectangular appearance with a vertical face and vertical side walls. The portions of the skirt between the outwardly extending projections extend inwardly to form a discontinued waist having an undercut which defines the cavity in the waist portion; the cavity being defined by a higher and less inwardly extending undercut over the top portion of each of the outwardly extending projections. Beneath the projections and the waist portions between them there extends outwardly and downwardly a lower band portion; below which may be a vertically extending wall, and which may have an outwardly turned lip at its bottom. The lid is generally formed of thin, flexible plastic, such as polystyrene usually by a thermoforming process on male moulds, from which the lid may be easily stripped. The lid has a lower stacking height and is less likely to be stripped from a cup by rubbing against another lid on another cup. File No. PAT6096
