Abstract

Abstract This invention relates to a Coaster holding or supporting a glass containing a drink for the purpose of preventing the marring of furniture by a dripping sweat formed on the outer surface of the glass and it comprises a non-frangible dished tray of non-porous material in which is placed an insert or pad comprising a base having a knap of highly porous material on one side thereof which will readily absorb the condensation or sweat running down the outside of a glass resting upon the knap of the insert as well as absorbing slight spillages. The insert has a coating of pliable substantially non-porous, non-moisture absorbing material on its under surface which engages the interior of the base of the dished body. This coating prevents slippage of the insert upon movement of the glass. The entire insert is readily removable from the non-frangible body and may be at desired intervals placed in an automatic clothes washer or otherwise washed to completely clease it, and it may be dried in an ordinary clothes dryer or any other suitable manner and thus should prevent mold and musty odors from the insert with its continuous use.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 207 words
A coaster for supporting a glass containing a drink, having an annular upstanding side, an insert removably placed in said coaster and composed of a single piece of material shaped to conform to the interior shape of the coaster and snugly fit therein covering substantially the entire bottom of the coaster, said insert being of one continuous piece free from cuts or openings therein, said insert comprising a woven base and a liquid absorbent knap on its upper surface of soft yielding material to firmly support a glass thereon and to absorb any condensate or spillage running down the outside of the glass, said insert being made of material of such nature that it may be washed in an ordinary washing machine without shrinkage or disfiguration, thereby permitting it to be reused after washing, the edges of the annular upstanding side projecting above the uppermost tips of the knap and wherein the tips of the knap are individual units to provide minute air spaces between the individual units of the knap, a layer of liquid non-absorbing material being attached to the surface of the woven section of the insert to prevent rotary slippage of the insert within the coaster when the glass is handled by a person.
