Container structure for removal of vacuum pressure

US-8152010-B2

Abstract

A hot-fill PET container or bottle ( 10 ) for filling with a liquid at an elevated temperature has a side wall ( 9 ) extending to a lower portion including a pressure panel ( 11 ) and a base ( 2 ) in its unfolded or pre fill position. The panel ( 11 ) is transversely oriented and has a decoupling or hinge structure ( 13 ), an initiator portion ( 1 ) and control portion ( 5 ) of a steeply angled inverting conical section between 30 and 45 degrees. The control portion enables the inversion of the panel ( 11 ) into the container ( 10 ) to compensate for vacuum or reduced pressure induced within the container as the liquid cools down. The base ( 2 ) can also have a plurality of reinforcing ribs ( 3 ).
