Abstract: A disposable pre-filled baby bottle (10) includes a substantially cylindrical pouch (12) terminating in an open end. A substantially rigid annular ring (16) is positioned on the interior surface of pouch (12) at the upper portion thereof and molded thereto. Spiral threads (20) are disposed circumferentially about a portion of annular ring (16) and cooperate with threads located on a ring and nipple assembly (18) to attach the assembly onto disposable bottle (10). Annular ring (16) also includes a gripping collar (22) located below adjacent spiral threads (20). Collar (22) provides a gripping surface and thus facilitates the handling of bottle (10) as ring ad nipple assembly (18) is removed and replaced.
