Abstract
Abstract A disposable, nesting nursing device has an upwardly tapering outer housing of relatively rigid or stiff material open at the top and bottom. A collapsible thin walled bag open at the top is secured in the housing to contain liquid and the top of the housing is adapted to receive a nipple. In one embodiment, the open top of the bag is integrally formed with and supported by the upper, smaller end of the housing. In other embodiments, the bag is separately formed and the open top of the bag is fixed to the top of the housing or fixed in the upper half of the housing. When the nursing devices are nested, the top of each lower device pushes the bag of the device above it upward. When filled with liquid, the bag of each device extends downward within the housing.
