ABSTRACT:
A screw-on closure for bottles that initially works with an induction seal liner and provides a leak resistant reseal on the bottle after the liner is removed. The closure has a unique annular convex sealing surface that overlies the mouth of the bottle. The sealing surface and the closure body area supporting it are sufficiently massive to withstand the heat generated in an induction liner sealing process and have a geometry that promotes a line contact with the mouth of the bottle to ensure a drip resistant reclose. A dispensing aperture of the cap is sealed by a hinged flap that has its sealing surface areas strategically located relative to the hinge to ensure repeated drip free opening and closing dispensing operation.
