Abstract
A sift-resistant dispensing closure is disclosed. The sift-resistant dispensing closure includes a base, a lid, and a hinge connecting the lid to the base. The base contains a circular end wall, a cylindrical skirt extending downward from the periphery of the end wall, and a sift deck elevated from the upside of the circular end wall. The sift deck contains a deck surface surrounded by a first snap bead and a first sealing surface, and pouring holes formed on the deck surface. The lid contains a second snap bead and a second sealing surface that are formed on the underside of the lid and engage with the first snap bead and first sealing surface, respectively, to form a seal around the sift deck when the lid is in a closed position.
