UNIFORM DISPENSING MULTICHAMBER TUBULAR CONTAINERS

摘要

A multichamber container must have certain characteristics in order to uniformly dispense the contents of each chamber from the container. The outer wall of the container and the inner divider web walls must have certain characteristics. The inner divider web walls must be highly flexible while the outer container wall must be less flexible . The Deflective Force for the outer wall must be greater than the Deflective Force for the web walls. In addition, to alleviate the proble m of suckback of air into the container chambers, the outer wall should exhibit a specific Retention Index. This is a measure of the outer wa ll to remain deflected after the removal of the deflecting force. The inner divider web wall will have a lower Retention Index than the outer wall. By the proper selection of outer wall and web walls, there can be uniform dispensing from the dispenser.
