Abstract
An infant bottle with a collapsing insert comprises a cylindrical bottle providing a vertically-positionable supporting platform which acts upon the insert to remove trapped air prior to feeding. The bottle also comprises conventional portions including a cylindrical body, a threaded top opening, a nipple, an attachment ring, and a sanitary cap. The supporting platform is vertically moveable within the interior of the bottle being positioned and locked into position via a pair of spring-loaded buttons which protrude from opposing side surfaces. A user may depress the buttons, vertically relocate the supporting platform to remove trapped air, and lock said supporting platform in position by releasing the buttons.
