ABSTRACT:
A closure for a container having an open top surrounded by a container wall. The closure includes a top wall from which a hollow insert depends for reception within the opening of the container and further includes an outer skirt that depends from the top wall for releasably engaging an outer face of the container wall. The insert has a first seal and a second seal for sealingly engaging the inner face of the container wall. The second seal is formed upwardly of the first seal, and a channel is formed between the seals to prevent leakage through capillary action. Additional embodiments include a bulbous first seal, a reinforced closure for pressurization or vacuum applications, flat-bottomed external screw threads formed on the container to prevent a pulling force from separating the closure from the container, and an annular concavity formed in the closure to enable internal threads formed in the outer skirt to slip over the external threads formed in the container during attachment of the closure to the container by a pushing action.
