초록

The dispensing of substances from multi-chamber containers, such as tubes, can be controlled by the placement of a flow modifying unit in the dispensing nozzle of the container. The dispensing nozzle will have a plurality of channels, usually one for each chamber. The flow controlling unit is a constriction at an intermediate point, a point between the channel inlet and exit, in at least one of the channels. This constriction is sized to adjust flow so that the viscous substance from each chamber is dispensed at a set flow rate and in a set ratio, one to...
