ABSTRACT:
A flexible, snap-on closure for use in combination with a container neck in order to seal closed a container in a tamper-evident manner includes a flexible closure having a top surface, a cylindrical side wall, an inwardly protruding annular rib and an inwardly opening annular channel. The container neck is compatibly configured with a top rim defining the container opening and an outwardly opening annular channel disposed below the top rim such that the annular rib is configured to fit within the outwardly opening channel and the inwardly opening annular channel is configured to snugly receive the top rim. The closure further includes a bail handle attached to the side wall by means of two attachment ribs which are integral with the bail handle. The side wall of the closure includes score lines, there being one line on opposite sides of each attachment rib, such that upward lifting on the bail handle which is attached to the side wall by means of three frangible elements, results in the breaking of those frangible elements and the severing of the score lines such that the lower portion of the closure side wall is flared outwardly in order for the closure to be removed from the container neck. The closure has an increased axial height which is sufficient relative to its diameter to prevent removal of the closure without some disruption of the closure.
