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...


The invention claimed is: 1. A method of controlling the flow of a substance from at least one chamber of a multiple chamber tube container having at least two chambers comprising: providing a shoulder and a dispensing nozzle at one end and a crimp seal at another end of said tube container, said nozzle having a circular horizontal cross-section and divided into at least two separate channels, said shoulder receiving the substance from the at least one chamber, said dispensing nozzle having an input end having a first cross-sectional area above the shou...
