ABSTRACT:
What is disclosed is an expeller for expelling air from a liner-type nursing bottle which at the same time provides unified storage for liners, a nipple, and premeasured portions of powdered infant formula. The apparatus of the invention further comprises a hand stop which can be engaged with the nursing bottle shell to prevent the mother's hand from slipping along the surface of the shell when the shell is drawn downwardly over the three-part apparatus of the invention to expel air from within the liner.
