Patent ID: 8028847

Claim:
A baby bottle comprising, (1) a first compartment having a proximal end and a distal end, the proximal end comprising a substantially open bore, and the distal end comprising, an at least partially closed port, and a stabilization coupling mechanism first portion; (2) a top section having at least one of an outlet and inlet port, the top section adapted to couple to the first compartment proximal end; and (3) a second compartment having a first end and a second end, the first end comprising a partially closed cavity and a stabilization coupling mechanism second portion, the stabilization coupling mechanism second portion adapted to mate with the stabilization coupling mechanism first portion, generally preventing first compartment rotation relative to the second compartment, and wherein the first end is adapted to couple to the first compartment distal end, and the second end comprising a substantially open bore and a removably coupled end cap; wherein (i) the second compartment first end, further comprises an inner diameter greater than a first compartment distal end outer diameter, and is adapted to snappably couple to the first compartment distal end, (ii) the stabilization coupling mechanism first portion comprises at least one flange generally positioned on an external surface of the first compartment, and (iii) the stabilization coupling mechanism second portion comprises at least one outer surface extension adapted to be received by the at least one flange.
