ABSTRACT:
An air expelling apparatus includes a cylindrical member that has a shell body with a closed top end, an opened bottom end and a peripheral wall with an interior area. A disk-like stand, is integral with the bottom end of the shell body, with the interior area of the shell having its opening at a bottom portion of the stand. The stand has a top portion integral with the peripheral wall of the shell body, and has a lower peripheral wall. Lastly, the stand is capable of functioning like a handle when the cylindrical member is positioned within the shell body of any disposable baby bottle. The stand allows the cylindrical member to operate in a piston-like manner when positioned through the lower opening of any disposable baby bottle and be in contact with the liner of a disposable baby bottle to expel air.
