1. A no-stick coaster system (10) for interiorly collecting moisture from a glass and for precluding the sticking of the coaster to a supporting surface, the system comprising, in combination:
a bottom portion (14) in a cylindrical configuration formed with an imperforate circular base (16) below and a circular open top above with a cylindrical side wall (18) there between to form a chamber with a depth, the base and the top having a common diameter, the side wall having a height between 10 and 20 percent of the diameter of the base, the side wall having an interior perimeter and an exterior periphery; a top portion (22) in a cylindrical configuration formed with an apertured circular base (24) below and a circular open top above with a cylindrical side wall (26) there between to form a chamber with a depth, the apertured base having a plurality of apertures (28), the base and the top of the top portion having a common diameter essentially equal to the diameter of the base and top of the bottom portion, the side wall of the top portion having a height between 10 and 20 percent of the diameter of the base of the top portion, the side wall of the top portion having an interior perimeter and an exterior periphery essentially equal to the interior and exterior peripheries of the bottom portion; an annular ring (32) depending from the base of the top portion in a direction opposite from the side wall of the top portion to form a recess, the recess having a depth between 20 and 40 percent of the depth of the chamber of the top portion; a hinge (36) coupling the top portion adjacent to the base of the top portion and the bottom portion adjacent to the top of the bottom portion, the hinge adapted to pivot the top portion between an operative closed orientation with the top portion overlying the bottom portion, and an inoperative open orientation with the top and bottom portions positioned laterally side by side with the hinge there between; an elastomeric O-ring (40) positioned within the recess, the O-ring being in contact with the annular ring and the base of the top portion and the side wall of the bottom portion adjacent to the top of the bottom portion when in the closed orientation; and an absorbent sheet of mold free filter material (44) positioned in the chamber of the bottom portion, the sheet of mold free filter material being adapted to collect moisture from the glass on the base of the top portion, the sheet of mold free filter material adapted to change color when wet and to be discarded when wet by pivoting the top portion to the open orientation and inverting the system. |
