摘要：
A device is provided comprising a heat source material which is a phase change material and which undergoes an exothermic phase change upon activation by an activating agent to generate heat, a heat source chamber holding the heat source and an activation chamber providing the activating agent, and a barrier separating the interior of the heat source chamber from the interior of the activation chamber, wherein the activation chamber is deformable and wherein deformation of the activation chamber causes rupture of the barrier to allow contact between the activating agent and the heat source material. Embodiments also provide an activation chamber for use in the device and comprising an activating agent to trigger activation of a heat source material.
