ABSTRACT:
A hermetically sealed container is provided in which a cup-shaped overcap overlies an externally threaded dispensing outlet and is hermetically bonded to the bottle neck. An outer jacket ring is provided to jack the overcap off of the bottle neck when the jacking ring is rotated downwardly. The overcap carries a wiper seal which engages the dispensing outlet to prevent liquid flow out of the dispensing outlet until the overcap is removed. The container closure is tamper-proof in that the overcap cannot be threadedly engaged with the externally threaded dispensing outlet once the overcap has been jacked off the bottle neck.
