Abstract
Infant nursers use a disposable, flexible plastic liner in a rigid, reusable shell. Previously, it has been the practice when breast pumps are used to pump the breast milk into an intermediate storage container and then pour it into the disposable liner of the nurser, or another intermediate container for freezing. The present invention provides an adapter for use with existing breast pumps which allows the breast milk to be pumped directly into the liner of the nurser without the need for any valves or moving parts. The adapter snaps onto the existing 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.
