Dispenser pumps |
摘要 |
A dispenser pump e.g. for toothpaste has a plunger (21) connected to a proximal end of an elongate flexible plastics strip (22) which is run slidably along a guide track built into the discharge nozzle (14) of the pump alongside the discharge channel (63). The distal end of the guide track defines a bend which opens through a lateral slot into the discharge channel (63) just inside its external opening. Action of the plunger causes the strip (22) to slide back and forth along the track and round the bend, so that the tip of the strip is moved out of the mouth of the nozzle during dispensing but returns to block it and cut away residual product when the plunger is released.
