<p>A fluid dispenser is disclosed for dispensing a fluid from a pouch having a discharge passage that extends along a tortuous path. The dispenser has a dispenser station and dispenser mechanism in the dispenser station. In one aspect the dispenser mechanism comprises a backstop on one side of the dispenser path and a cam operated cylindrical roller confronting the backstop located on the other side of the dispenser path. The roller is attached to a roller bracket which is pivotally attached to the interior of a hollow pushbutton. The pushbutton is mounted in an opening in the dispenser front cover. Springs are attached to the bracket and the front cover which maintain the roller against the flexible dispenser compartment of the pouch. Depressing the pushbutton forces the roller to trap the upper portion of the pouch flexible dispenser compartment between the roller and backstop to initially seal the dispenser compartment at its upper end and further pushbutton action forces the roller down the dispenser compartment thereby causing expulsion of the fluid trapped in the dispenser compartment.</p>
