Claim:
A system, comprising: a container including a sidewall and a bottom wall, a neck region on the sidewall adjacent to an opening opposite the bottom wall, the container including projections spaced around the neck region, each projection including a cam surface, a lock surface, a ramp, and a clamping surface; a closure including a closure plane and a circumferentially depending outer skirt extending from the closure plane, a tamper-evident arrangement frangibly connected to an edge of the outer skirt opposite the closure plane, pairs of lugs spaced around an inner sidewall formed by the outer skirt and the tamper-evident arrangement, a lock lug of each pair of lugs arranged on the tamper-evident arrangement and a sealing lug of each pair of lugs arranged on the outer skirt; wherein each lock lug is adapted to engage the cam surface of a corresponding projection during application of the closure to the container, the lock lug adapted to engage the lock surface of the corresponding projection after application of the closure to the container; wherein each sealing lug is adapted to engage the ramp of the corresponding projection during application of the closure to the container, the sealing lug adapted to engage the clamping surface of the corresponding projection after application of the closure to the container; wherein the closure and the container cooperate to provide a tamper-evident closure with the container after the application of the closure to the container, the lock lug configured to engage the lock surface to prevent removal of the closure until the tamper-evident arrangement detaches from the outer skirt, and wherein the sealing lug is configured to engage the clamping surface until after the tamper-evident arrangement detaches completely from the outer skirt.
