Abstract
An aerosol container having a propellant means and a flexible product bag enclosed within a flexible deformable plastic container such as polyethylene. The propellant causes the product in the bag to discharge which reduces the volume of the product in the enclosing container thus reducing the pressure of the gas within the container to subatmospheric pressure. This collapses the container and is an indication that the contents have been used.
