Abstract
A tamper-evident, snap-on, screw-off closure which is used with a specially shaped container neck is provided with a foil liner. Once the closure is applied to the neck, the foil liner is sealed to the neck of the container. The foil liner includes a tab for removal of the seal disc from the neck. The closure is characterized by the absence of a second liner between the top of the cap and the foil liner. The closure, neck and the foil liner are formed to inhibit adherence of the tab to the cap interior and the neck exterior.
