Child-resistant closure and container package

摘要

A child-resistant closure and container package (20) includes a container (24) having a finish (52) with an external thread (54) and pockets (64) in the thread. A closure (22) has a base wall (26), a peripheral skirt (28) with an internal thread (30) and lugs (36) on the internal thread (30) for receipt in the pockets (64), and a spring element (42) on the base wall (26) for engagement with the container finish (52) to bias the closure away from the container finish (52) and resiliently urge the lugs (36) into the pockets (64). A liner (70) is urged by the spring element (42) into engagement with the container finish (52). The liner (70) may include a base with metal (76) and plastic (78) layers for induction-welded sealing engagement with the finish (52) such that, upon removal of the closure, the metal (76) and plastic (78) layers remain secured to the finish (52) and the liner (70) base is removed with the closure. The metal (76) and plastic (78) layers may be removed by a user for access to the contents of the container (24), and the liner (70) base continues to serve as a package seal during use of the package.
