Abstract
A dispenser pen for dispensing liquids such as adhesives has a tube 12 connecting a supply 14 of the liquid to a nozzle 15. The tube 12 passes between a cross-pin 19 and one end of a pivoted lever 18 which is normally urged by a spring 23 to squeeze the tube 12 between the lever and the cross-pin so as to close the tube to flow of the liquid. The region 17 of the tube between the lever 18 and the cross-pin 19 is predeformed to a generally flattened shape which can open to permit flow of liquid but can be closed with little force and by a short movement of the lever 18.
