A dispenser pump, for fitting to a container neck to dispense liquids in small doses, has a pump body (39) with a fixed discharge nozzle (25) and a reciprocable plunger to pump liquid through the valved inlet (41) of the pump chamber and out through the discharge nozzle. To enable the pump body (39) to be recessed into the container neck, the discharge nozzle (25) near the top of the pump chamber and the outlet near the bottom of the pump chamber are connected by a discharge channel (48) extending up through the pump body alongside the pump chamber (38). Also described is a tamper-evident locking closure which holds the plunger (70) in a particular rotational orientation in which it is locked down. Breaking and removing the tamper-evident element simultaneously turns the plunger (70) to free it to rise. |
