Abstract: A disposable, sterile infant nurser comprising a resilient, liquid-impermeable container bag the peripheral edge of which has a corolla-like configuration; a relatively rigid, upstanding circular neck secured to an opening in the bag, the neck including means for holding the nurser projecting radially outwardly adjacent the base of the neck; an apertured nipple releasably secured to the neck; and a removable cover overlying the nipple and holding it in retracted position substantially within the confines of the neck. A measured amount of dry infant formula is provided within the container bag adjacent the perimeter of the bag. The nurser is completely self-contained, lightweight, compact, adapted for home or hospital use, and can be packaged by vertical stacking in a sterile container.
