ABSTRACT:
A disposable coaster for use with a beverage container is characterized by a substrate of moisture absorbent material having a base panel and an upstanding side wall joined to the base panel, thereby forming an open ended shell for receiving the bottom end of the beverage container, with the upstanding side wall being characterized by folded, overlapping side wall segments defining vertically extending pleats. A film deposit of moisture impervious sealing material applied to the exterior surface of the shell strengthens the pleats, improves tear resistance and prevents leakage.
