Abstract

A closure for opening and reclosing a package includes a base attachable to the top of the package over a scored area thereof, and a lever pivotally connected to the base at a rearward portion of the base so that by pivoting the lever, a portion of the lever penetrates the scored area of the package, and eventually, another portion of the lever seats over the open area of the package to provide a pouring spout. A removable cover is provided over the seating portion of the lever so that re-opening and resealing of the package occurs by removing the cover.
