A CONTAINER FOR A SELF-HEATING DEVICE

摘要

The container (16) consists of a base (18), an upstanding wall (20) which is at least partially transmissive to microwave energy and a lid (24). The container (16) is suitable for use with a self-heating device(2) containing an exothermic phase change material that can be re-charged using microwave energy. The device (2) includes a diaphragm (6) to accommodate volumetric changes of the exothermic phase change material during the phase change process and the lid (24) of the container (16) includes a cavity (29) into which the diaphragm (6) can expand with the wall of the cavity (29) preventing the diaphragm (6) from expanding too far. The self-heating assembly enables the self-heating device (2) to be re-charged using microwave energy without the deleterious effects commonly encountered.
