ABSTRACT:
Infant nursers use a disposable, flexible plastic liner in a rigid, reusable shell. An adapter allows the breast milk to be pumped directly into the liner of the nurser without the need for any moving parts in response to cyclic pressure variations in the reservoir of the adapter. The adapter snaps onto the nipple-retaining cap and uses the liner of the nurser itself to form a valve. In a second embodiment, the adapter is provided with a unitary threaded circular rim to attach directly to the threaded end of the nurser shell. The adapter also includes a trigger for manual actuation of the valve when unmodulated negative pressure is applied to the reservoir.
