ABSTRACT:
A flexible closure for a container, such as a blow molded jug, having a neck portion with an inturned flexible flange surrounding an opening therein and a pair of vertically spaced fastening configurations on the exterior thereof; the closure having a cap portion with an annular depending flange on its peripheral edge and at least one depending annular flexible sealing flange inwardly thereof for engagement with said inturned flange on said neck portion. A tear skirt is removably attached to the annular depending flange, the tear skirt having a pull tab for the removal thereof. An out-turned annular flange is formed on said tear skirt and a plurality of circumferencially placed gussets join said angular flange and said tear skirt. The closure has dual fastening configurations, either one of which is capable of holding the closure on the neck portion of the container. When the tear skirt of the closure is removed the opposite sides of the depending flange of the flexible closure may be moved inwardly to engage ribs on the neck portion so that twisting the closure removes it and the annular sealing flange from the neck of the container.
