A can cover plate is provided having an underside surface sealably engagable with the can top rim. A can support plate is oriented below and opposing the can cover plate and is designed for supporting the can. An expansible back connects the can cover and support plates in expansible and contractible opposing relation to permit the can closure to close down upon and sealably engage the can top rim.
