Abstract
A method of filling a collapsible package in a cartridge for use with a caulking gun is provided. The method comprises pressurizing an internal space of a collapsible package to expand the package. Drawing a vacuum external to the collapsible package and removing the positive internal pressure. The vacuum maintains the package in an expanded state. A nozzle is then inserted into the collapsible package to reverse fill the package with a vicious material.
