ABSTRACT:
The invention provides a float member for use in conjunction with similar float members for substantially completely blanketing or covering the surface of a liquid to reduce evaporation, and/or to suppress waves, the emission of noxious or toxic fumes and the formation of foam. The float member comprises a body having a hexagonal circumferential skirt or wall at least 0.2 inches (5mm) in depth and is so shaped and/or weighted that it tends to flaot in only one of two dispositions with its hexagonal skirt disposed at the level of the liquid with such skirt extending substantially at right angles to the surface of the liquid.
