Abstract: A sealing plug for a liquid-filled container having a lower opening therein with an extended skirt thereon. The plug comprises a peripheral cylindrical wall for sealingly engaging the skirt of the container. The plug further has a flanged annular base extending inward from the peripheral wall and has two or more supports extended upward therefrom, the supports each have an upper end for collectively supporting an ornament within the container. The plug further has a flexible inner wall extending upward from the annular base, to a height lower than the height of the supports, and contoured around and inboard of the supports. The plug finally has a flexible diaphragm extending across the upper end of the inner wall for compensating for changes in volume and pressure of the liquid within the container.
