A container (4) with a secured closure (12) is provided with a sealing system having an inflatable seal (20). A user actuated pneumatic or hydraulic pump (36) supplies a quantity of air to inflate the seal. When the seal is inflated, a surface of the seal acts against surfaces of the container and the closure to effect a hermetic seal. The air may be selectively released from the inflatable seal by the user of the container to facilitate access to the contents of the container. Conversely, the air may be selectively pumped into the inflatable seal by the user to provide a secure, impermeable seal when the container is closed.
