ABSTRACT:
A multi-functional coaster has a vessel-supporting platform and extending from the periphery of the platform one or more additional constructional features enabling the coaster to be used also as a bottle opener and/or a sealing lid for a beverage can and/or a can opening tab lifter. The bottle opening feature is formed by a radial flange of claw-like cross-section and an axial skirt on which is provided a sharp-edged radially outwardly projecting portion for engaging the rim of a bottle cap. The flange simultaneously provides means for assisting leverage of a can tab by inserting it between the tab and the roof of the can, or alternatively a flange may be provided on its own for that purpose. The sealing lid feature is provided by a radially inwardly projecting step on the skirt, which forms a recess for releasably and sealingly engaging the lip on the top of a beverage can. This feature may be provided on its otwn on the skirt or in conjunction with the bottle opening feature. The whole coaster can be easily and cheaply molded from plastic. Optionally, the part of the skirt forming the cap rim-engaging part of the bottle opener is provided by a metal insert.
