Air expelling apparatus for a nursing bottle

A new and improved air expelling apparatus for expelling air from a disposable baby bottle liner comprising in combination:

• an elongated cylindrical member having a shell body with a closed top end, an open bottom end and a peripheral wall therebetween, the shell body having an interior area, the peripheral wall of the shell body having a length of about 51/2 inches and a diameter of about 2 inches, the shell body having a generally tapered peripheral edge continuous with the peripheral wall and integral with the top end;
• a disk-like stand being integral with the bottom end of the shell body, the interior area of the shell body having an opening at a bottom portion of the stand, an air pocket being within the bottom portion and traversing completely around the stand, the stand having a top portion integral with the peripheral wall of the shell body, the stand having a lower peripheral wall with a generally tapered peripheral edge continuous therewith, the tapered peripheral edge of the stand being integral with the lower peripheral wall and the top portion, the lower peripheral wall and the peripheral edge combined having a height of about 3/8 inch, the stand having a diameter of about 3 inches, the stand being positioned on a receiving surface and capable of allowing the cylindrical member to sit thereon in a vertical orientation, the diameter aiding in the stability of the cylindrical member when in the vertical position and the air pocket will disallow suction-like contact between the stand and a receiving surface;
• and
• the stand being capable of functioning like a handle when the cylindrical member being positionable within a shell body of a cylindrical disposable baby bottle, the stand being capable of continuously moving the cylindrical member along a rectilinear path in a direction away from and toward a lower opening of a cylindrical disposable baby bottle, the stand being capable of allowing the cylindrical member to operate in a piston-like manner, when positionable through the lower opening of a cylindrical disposable bottle, by allowing the cylindrical member to be in and out of contact with a liner within the disposable baby bottle, the cylindrical member being moved into and out of contact with the liner being capable of varying the volume of the liner for expulsion of air from therein and preventing reentry of air within.
