<p>The device (201) has a closed compartment containing a primer element i.e. concave pellet (30), and a supersaturated solution (S) at room temperature for generating an exothermic reaction when the solution undergoes a disturbance caused by the concave pellet. The closed compartment includes walls made of sheets of flexible plastic material. The pellet is surrounded in a rigid plastic ring, where the pellet is made of plastic material, and the ring has a height greater than twice the height of concavity of the pellet.</p> |
