Abstract
A self-insulating fluid container having a novel thermally responsive side wall is disclosed. The side wall is constituted of multiple layers that thermally respond to the presence of fluid of at least a predetermined temperature in the fluid container in a coordinated manner. In one embodiment, the coordinated thermal response either creates or increases insulating air space between an innermost and an outermost one of the layers. In another embodiment, the coordinated thermal response increases insulation of an intermediate layer between an innermost and an outermost one of the layers. In one embodiment, the self-insulating container is a cup for holding a hot beverage.
