An improved collapsible bag for containing a product to be dispensed from an aerosol container. The improved collapsible bag has an opening at one end and is closed at an opposite end and comprises an upper section, a mid-section and a lower section. The upper section includes a neck portion, a curl portion and an outwardly tapering section. The mid-section, in an inflated state of the collapsible bag, is generally cylindrical in shape and is contiguous with the outwardly tapering section. The lower section tapers inwardly and defines the closed end of the improved collapsible bag and the lower section is contiguous with the mid-section. At least the curl portion of the upper section has a sufficient wall thickness to facilitate a fluid tight seal between a bead of a container and a perimeter curl of a mounting cup, during assembly of an aerosol valve, while a remainder of the upper section, the mid-section and the lower section all have a sufficiently thin wall thickness to facilitate collapse and substantially complete dispensing of the product to be dispensed from the improved collapsible bag.
