ABSTRACT:
A collapsible flaccid bag bottle, such as those used for baby bottles, for closed containment of fluid to be aspirated therefrom. Integral with the bottle is a thin passive film, for example, a 2 mil thick additional layer of plastic, that passively manages collapsing of the bottle as fluid is dispensed. The presence of this layer insures against sustainment and proliferation of fluid retention pockets that typically proliferate inside of flaccid bags and block discharge passage of fluid.
