A closure has a base wall, a peripheral skirt with an internal thread and lugs on the internal thread for receipt in the pockets, and a spring element on the base wall for engagement with the container finish to bias the closure away from the container finish and resiliently urge the lugs into the pockets. A liner is urged by the spring element into engagement with the container finish. The liner may include a base with metal and plastic layers for induction-welded sealing engagement with the finish such that, upon removal of the closure, the metal and plastic layers remain secured to the finish and the liner base is removed with the closure. The metal and plastic layers may be removed by a user for access to the contents of the container, and the liner base continues to serve as a package seal during use of the package.

Abstract: A package for tablet products that includes a container having an interior volume for holding the tablet products and a closure secured to a cylindrical finish of the container. A product hold-down device has an axially resilient central portion, a lower portion for engaging the upper surface of the product within the container, and an upper portion for securement within the container finish to hold the device in place within the finish, with the closure removed from the finish, against the axially resilient forces applied to the device by engagement of the lower portion with product in the container and resilient compression of the central portion of the device. Thus, the hold-down device can be inserted into the container and secured to the container using automatic packaging equipment, and the container closure then applied to the container. In use, the closure is removed from the container, and the device is removed and discarded by the user.
