ABSTRACT:
A coaster for use underneath liquid containers, such as drinking glasses, beverage cans, etc., comprises an upper pad formed of a liquid-absorbent material and a lower pad formed of a thermal insulating material. The two pads are separated by a liquid barrier material so that the insulating pad is maintained in a dry operable condition. A series of adhesive patches are arranged on the upper face of the coaster, whereby the coaster can be releasably attached to the bottom surface of a liquid container.
