Abstract:
A new baby nurser with plunger device for evenly expelling excess air for a nurser-style bottle comprising, in combination:a baby nurser comprised of a shell having an open upper and an open lower end, the baby nurser including a liner positioned within the shell for holding baby formula therein, the liner having an open upper end positioned within the open upper end of the shell, the baby nurser including a nipple secured to the open upper end of the shell and being in communication with the open upper end of the liner for receiving formula therein; a plunger portion including a circular base, the plunger portion including a frustoconical post extending upwardly from the circular base, the post having a flat upper free end, the post being dimensioned for being received within the open lower end of the shell of the baby nurser; a rubber dome positioned within the open lower end of the shell below the liner therein, the rubber dome having an open lower end for receiving the flat upper free end of the post therein whereby pressure from the plunger portion will force the rubber dome upwardly within the shell thereby urging excess air within the liner to be expelled outwardly through the nipple, the rubber dome member remaining within the shell abutting the liner throughout nursing to inhibit the reintroduction of air into the liner, the rubber dome frictionally engaging sides of the shell to inhibit the rubber dome from sliding away from the liner.
