The invention relates to a collapsible bag in squeeze bottle fluid dispenser. The problem associated with collapsible bag squeeze bottles is that the collapsible bag collapses upon itself near the discharge opening chocking off fluid flow. A suitable bag support member is inserted inside the flexible bag (40) to prevent substantial axial movement of the bag (40) in the direction of its discharge orifice (42) and to encourage radial collapse of the bag (40) instead. The internal bag support member which in a pre- ferred embodiment comprises an extruded plastic helix (60) has an internal fluid passage formed within the coils of the helix. Thus, radial collapse of the flexible bag (40) does not block the passage of fluid remaining in the bag (40) through the discharge orifice (42) in the bag until substantially all of the fluid contained within the bag has been dispensed.
