A container closure system comprising a threaded cap and a threaded neck wherein the cap is affixed to the neck by direct axial application so that the mating threads slip past one another and into engagement. The cap further includes sealing means to capture and constrict the outer diameter of the neck, and valve means to plug the container opening in the neck and expand the outer diameter of the neck, so that the sealing means and valve means cooperate to improve sealing of the cap and neck. The cap and neck further include tamper-indication means to prevent removal of the cap without activation thereof. The tamper-indication means includes a novel lower skirt, having at least three pull-tabs substantially symmetrically positioned around the lower skirt and the lower skirt being removable in a single piece by pulling upon any single pull-tab. The container neck may further include interrupted threads which do not traverse the parting line and an additional annular seal below the threads on the container neck.
