| 摘要 |
A container for containing a heated liquid and having a longitudinal axis. The container comprises at least one substantially vertically folding vacuum panel portion disposed substantially transversely relative to the longitudinal axis, the vacuum panel portion adapted to compensate for vacuum pressure changes within the container caused by heating or cooling of a liquid contained within the container. The vacuum panel portion comprises an initiator portion and a control portion, with at least a portion of the control portion being more steeply inclined relative to the longitudinal axis than at least a portion of the initiator portion. The initiator portion causes the control portion to flex inwardly into the container. The pressure panel inverts vertically in a direction substantially parallel to the longitudinal axis.
