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.
