SPENDER FUER VISKOSE FLUESSIGKEITEN.

摘要

A dispenser (10) for liquids including a cartridge (18) containing a liquid, a nozzle (30), and a hollow flexible bladder (34) between the cartridge (18) and the nozzle (30). An assembly (39) can be manually rotated to provide a high mechanical advantage and incrementally drive a piston (24) through the cartridge (18) to thereby fill the bladder (34) with liquid from the cartridge (18) and discharge any plug of solidified material (e.g., diluted phosphoric acid) that may be present in the nozzle (30); and manually operated button (40) can be pressed to quickly and controllably collapse the bladder (34) to thereafter dispel liquid within the bladder (34) through the nozzle (30).
