US Patent 9869503 Tray for forming frozen solids

A tray for forming frozen solids such as ice cubes is described. The tray includes a plurality of cavities, each cavity having a base, sidewalls, and a top edge. An overflow notch including an aperture is located in the top edge of each cavity. The overflow notch is of a sufficient depth such that when the tray is filled with liquid up to the level of the overflow notch, and then placed in a freezer to form cubes of frozen solids, connections of frozen solid are not formed between the cubes, even if the liquid expands when it freezes.
