ABSTRACT:
An ice cube tray comprising a body of plastic or pressure die cast material or sheet metal having generally relatively thin uniform thickness throughout, and a top wall with at least the central portion thereof having a flat top surface. The flap top surface has a plurality of longitudinally spaced openings and a bottom wall and side walls extending downwardly from the edges of each opening to define a cavity. Each bottom wall is arcuate in a transverse direction. Depressions are provided in the top wall at the juncture of the bottom walls or side walls to form water level control surfaces to maintain the water level to form an ice cube whose top surface is at or below the center line forming the said arcurate wall.
