Abstract
A pump for fixing onto a receptacle to dispense a substance contained therein. The pump has a pump body that includes at least one air intake vent. A pushbutton is movable relative to the pump body between a low position and a high position. A suction valve includes a shutter-forming member. A piston co-operates with the pump body to define a pump chamber of variable volume. Also, a dispenser duct is provided through which the pump chamber can communicate with a dispenser orifice. A sealing skirt surrounds the dispenser duct on at least a fraction of the height of the dispenser duct. The sealing skirt is configured to co-operate with the pump body when the pushbutton is in its low position so as to isolate the vent from an outside ambient environment. As examples of a few aspects, the dispenser duct is provided as an element attached to the pushbutton and the piston is movable relative to the dispenser duct.
