A tamper-evident package with pressurized contents which includes a closure and associated container which cooperate to provide desired tamper-evidence upon initial removal of the closure from the container, while promoting convenient and comfortable removal and use by consumers.

Tamper-evident bottle and closure having vents

A plastic closure is disclosed which is configured for enhanced performance and reduced closure weight. Notably, the closure includes a compound, internal helical thread formation including an upper retention portion which provides desired closure hoop strength and sealing performance, and a lower guide portion which is configured for light weight while functioning to guide the closure onto an associated container during application. The closure can further include a stepped top wall portion having a relatively thick outer region, and a relatively thin central region. A tamper-evident band of the closure can be configured to include a deformable free edge portion for enhanced tamper-resistance.
