1. A sealing plug, for a liquid-filled container having a lower opening therein with an extended skirt thereon, having a fixed peripheral portion for sealing the container and supporting an object within the container and having a flexible diaphragm for adjusting to changes in volume and pressure of the liquid within the container, said plug comprising: a peripheral wall for sealingly engaging the skirt of the container and having an upper end thereof with two or more supports extended upward therefrom for supporting an object within the container, and a flexible diaphragm having an upper surface and a recessed annular channel around the periphery thereof connected to said wall and extending across the upper end of said wall. 2. The sealing plug as defined in claim 1, wherein said recessed channel includes a flange extended downwardly from the upper surface and connected to the wall by an annular flange. 3. The sealing plug as defined in claim 2, wherein the depth of the recessed channel is about one-half the height of said wall and said annular flange is connected at about the center of said wall. 4. The sealing plug as defined in claim 1, wherein said diaphragm further includes at least one annular corrugation. 5. The sealing plug as defined in claim 1, wherein the upper surface of said diaphragm further includes an aperture for sealingly engaging an object extended through the plug into the container. 6. The sealing plug as defined in claim 5, wherein the upper surface of said diaphragm further includes a second recessed annular channel extended about said aperture. 7. A sealing plug, for a water globe having a lower circular opening therein with an extended cylindrical skirt thereon, having a fixed peripheral portion for sealing the globe and supporting an object within the globe and having a flexible diaphragm for adjusting to changes in volume and pressure of the water within the globe, said plug comprising: a cylindrical peripheral wall for sealingly engaging the skirt of the globe and having an upper end thereof with two or more supports extended upward therefrom for supporting an object within the container; and a flexible diaphragm having an upper surface and a recessed channel around the periphery thereof connected to said wall and extending across the upper end of said wall. 8. The sealing plug as defined in claim 7, wherein said recessed channel includes a flange extended downwardly from the upper surface and connected to the wall by an annular flange. 9. The sealing plug as defined in claim 8, wherein the depth of the recessed channel is about one-half the height of said wall and connected at about the midpoint of said wall. 10. The sealing plug as defined in claim 8, wherein the upper surface of said diaphragm further includes an aperture for sealingly engaging a shaft extended through the plug into the globe.
