Abstract

Dispositivo de seguridad en cierres estancos de pilas electroquímicas, de las dotadas de una constitución general que comprende un contenedor metálico (1) conteniendo separadamente los materiales activos que constituyen el ánodo (2) y cátodo (3), caracterizado porque, enfrentada a la cara inferior de la tapa (5), la pieza plástica (4) tiene una cara superior que presenta tres canales (12) dispuestos radialmente a 120º, estando formados por rebaje del grosor nominal y normal del material de la placa (4), comprendido entre la sección debilitada (10) y el muro periférico (7), cuyo rebaje es progresivamente mayor en el sentido hacia el centro de la pieza plástica (4) y determina una paulatina disminución del grosor del suelo anular (8), o una creciente profundidad de los canales (12), en el sentido desde el muro periférico (7) hacia el núcleo (6), siendo el grosor más fino del suelo anular (8) ligeramente mayor que el de la sección debilitada (10).
