Fluid container closure system

Abstract

A fluid container closure system includes a fluid outlet, a neck finish adjacent to the fluid outlet, wherein the neck finish includes a retaining rim, protruding in a radial outward direction and encircling the neck finish. A screw cap includes a base with a top deck and a skirt and a tamper evident band with a base having a lateral inner surface. The screw cap includes a predetermined breaking structure along which the skirt and the tamper evident band are interconnected. The tamper evident band includes a lip extending along the inner lateral surface of the tamper evident band base and inwardly therefrom, wherein the lip includes a hinge section and a retaining surface configured so when the screw cap is initially applied to the fluid container, the lip is folded upward about the hinge section such that the retaining surface in an applied position of the screw cap is positioned underneath the retaining rim.
