Abstract (en)
[origin: WO9735777A1] A mechanical pump dispenser spout (10) has an inlet end (16), an outlet end (18) and a fluid-containing portion (14) therebetween. The fluid-containing portion (14) is angled upward from the inlet end (16) to the outlet end (18). The spout (10) also has a first one-way discharge valve (20) located at the inlet end of the spout (10). The first one-way discharge valve (20) is adapted to minimize air entering the pump from the spout (10). A second one-way discharge valve (24) is located at the outlet end of the spout (10) to minimize dripping of fluid from the fluid-containing portion (14) of the spout (10). The second one-way valve (24) faces downward. The first and the second one-way discharge valves open when the pump is actuated and close when the pump actuation is completed.
