Abstract: 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.

Abstract: 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.

Abstract: A tamper-evident package having pressurized contents 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. In particular, the package is configured such that from a fully applied position of the closure on the container, the closure is movable through a predetermined angle prior to actuation of the tamper-evident feature on the package. In this fashion, the torque which must be applied to the closure for overcoming the static friction at the sealing interface between the closure and the container can be overcome prior to the application of torque required for operating the tamper-evident feature of the package. The present invention contemplates enhancing the opening performance of the package by configuring the package to include certain structure features to facilitate convenient, consistent, and comfortable use by consumers.
