    Patent number: 4148416
    Abstract: In an aerosol dispensing container of the kind having a collapsible bag separating the propellant from the product to be dispensed, an elongate core member is arranged completely free, loose and unattached within the bag to prevent pockets of product becoming isolated from the dispensing valve when the bag collapses. The core member provides a path, unaffected by bag collapse, for the product to pass to the valve.
