ABSTRACT:
A coaster for containers of hot or cold liquids that more effectively insulates the container from both the outer walls and base of the coaster, and that does so for longer periods of time of continuous use than known devices. Among other features, the coaster impedes the formation of condensate water on its outside walls and base, and provides an improved non-adhering adsorbent layer to receive and contain the container and receive the condensate drained from its walls.
