A closure system for a fluid outlet is disclosed which includes a motor threadably connected to a hub which, in turn, is connected to a closure element or cup that provides a sealing cover beneath one or more nozzles. The action of the motor initially lowers the closure element vertically before pivoting the closure element away from the area directly beneath the nozzle or nozzles. After fluid is dispensed, a biasing element pivots the closure element back into place before it is raised vertically again to provide a seal or cover for the one or more nozzles. The hub is designed to pivot only a partial revolution and the pivoting action of the hub and closure element away from the nozzle area overcomes the bias of the biasing element contained within the hub. The biasing element then pivots the hub and closure element back into place before the biasing element raises the hub and closure element to its original position.
