Abstract
Generally, an infant nursing system will include a holder having an open end, for holding and engaging a collapsible liquid containing bag. The collapsible bag defines a chamber and has an open end permitting fluid communication with the chamber. The open end is also used for engaging the open end of the holder. The novel bag may include flexible material, having a permeability sufficient to hold a fluid, wherein the flexible material is arranged in a generally tubular shape, defining a first end and a second end. The second end is sealed in a fluid tight fashion, thereby forming a chamber for holding fluid. The first end engages the open end of the holder. A pair of flaps is formed at the first end for assisting in opening the bag to provide access to the chamber. A gripping member is formed on the pair of flaps, for enhancing the gripping of the flaps. It is preferred for the gripping member to include holes formed in the flaps or textured surfaces. In an especially preferred embodiment, the bag further includes sealing members for releasably sealing the first end of the bag.
