Abstract
A measuring dispensing closure for a container includes a hollow body having an opening therein, and a pivotable flip top. The flip top is mounted on the body for pivotal motion about a horizontal hinge axis between closed and open positions. The hollow body has an internal, part spherical weir panel located below the opening, with an edge extending parallel with the hinge axis thus establishing a weir opening between the weir edge and a peripheral portion of the opening, and defining, in cooperation with an underside portion of the flip top and a remaining peripheral portion of the opening, a measuring chamber within the closure. The flip top is also formed with a shut-off blade adapted to engage the weir edge when the flip top is in the open position.
