Cartridges for dispensing gel-like substances

摘要

A cartridge for dispensing a substance in a gel-like form comprises a body having a discharge nozzle at its forward end and a piston movable through the body to dispense the product through the nozzle. The interior configuration of the nozzle is such as to prevent dripping of the substance from the nozzle if the cartridge is inverted and preferably this effect is obtained by forming the interior of the nozzle with a venturi-like profile.
