<p>The container has a wall (1) which is resistant to the pressure of the smoke-generating compound (4) inside it while it is undergoing an exothermic reaction, and a zone (3) of reduced resistance, created by a relatively thin layer. The zone (3) is covered by a lid (2) which has a resistance comparable to that of the main wall (1), and is pierced with a series of holes (6, 7, 8). Each of the holes in the lid has an edge which is shaped to form cutting irregularities, and the zone (3) of reduced resistance beneath the lid is made from an aluminium film layer.</p> |
