The depressible actuator of the pump has a closure plug hingedly and integrally attached thereto in association with an integral toggle so that the plug may be snapped between a pair of opposite over-center positions about the hinge point. In one of the positions, the plug may be inserted snuggly into the otherwise open end of the dispensing spout of the pump so as to close and seal the latter, while in the other over-center position the plug is snapped back into a fully clearing relationship with the spout to not only open the latter but also remain out of the path of discharging travel of product emanating from the spout. When the plug is securely received within the spout, it cannot be pulled out merely by depressing the actuator, and thus the actuator becomes effectively locked against depression at that time.
