ABSTRACT:
Disclosed is a closure for a container, such as a blow molded jug having a neck surrounding an opening therein, the closure having a first annular portion and a second annular portion. The first annular portion in the closure has a wiper seal and a lip seal. The second annular portion exerts an upward pressure on the lip seal which causes improved sealing and leak-tight properties during shipping, handling, etc. The upward pressure also enhances the effectiveness of the wiper seal. The second annular portion may include an annular tear skirt having a pull tab for the removal thereof to facilitate removal of the closure from the container. The closure may also include a plug seal, and a lower annular portion extending from the second annular portion.
