Abstract

A trigger pump dispenser has a dispensing passage, an outlet nozzle movable between an “on” position and an “off” position, and a shroud. First and second indicator tabs project from the outlet nozzle and correspond with first and second indicator windows in the shroud. When the outlet nozzle is in the “on” position, the first indicator tab resides in the first indicator window and the second indicator tab is hidden by the shroud, and when the outlet nozzle is in the “off” position, the second indicator tab resides in the second indicator window and the first indicator tab is hidden by the shroud.
