Abstract
A container has a longitudinal axis, and comprises an upper portion including an opening into the container, a sidewall portion extending from the upper portion to a lower portion, the lower portion including a base, and a pressure panel located in the lower portion substantially transversely to the longitudinal axis, the pressure panel being movable substantially along the longitudinal axis between an initial position and an inverted position to compensate for a change of pressure induced within the container. The pressure panel comprises an initiator portion and a control portion, the initiator portion adapted to move in response to the change of pressure prior to the control portion.
Claims13
A container having a longitudinal axis, and comprising:
- an upper portion including an opening into the container;
- a sidewall portion extending from the upper portion to a lower portion, the lower portion including a base;
- and
- a pressure panel located in the lower portion substantially transversely to the longitudinal axis, the pressure panel being movable substantially along the longitudinal axis between an initial position and an inverted position to compensate for a change of pressure induced within the container;
- wherein the pressure panel comprises an initiator portion and a control portion, the initiator portion being adapted to move in response to the change of pressure to cause the control portion to invert, and wherein the initiator portion is located closer to the longitudinal axis than is the control portion.

- a sidewall portion extending from the upper portion to a lower portion, the lower portion including a base;
- a pressure panel located in the lower portion substantially transversely to the longitudinal axis, the pressure panel being movable substantially along the longitudinal axis between an initial position and an inverted position to compensate for a change of pressure induced within the container;
- and
- a hinge structure connecting the pressure panel to the lower portion;
- wherein the pressure panel moves from the initial position to the inverted position in response to internal vacuum forces developed within the container as a result of cooling of liquid contents within the container, wherein the pressure panel comprises an initiator portion and a control portion, the initiator portion being adapted to move in response to the internal vacuum forces to cause the control portion to invert, and wherein the initiator portion is located closer to the longitudinal axis than is the control portion.
