Abstract

LA LATA DE ZINC (16) DE UNA PILA SECA ES CERRADA POR UN CIERRE (25) PREFORMADO EL CUAL, CUANDO ES SOMETIDO A PRESION DENTRO DE LA LATA, SE DOBLE PREFERENTEMENTE POR UNA REGION (27) ADYACENTE A LA VARILLA DE CARBON (121) PARA DESAHOGAR LA LATA Y ASI LIMITAR LA PRESION INTERNA. EL CIERRE ES PREVIAMENTE SOMETIDO A UN ESFUERZO PARA QUE SE CIERRE AUTOMATICAMENTE CUANDO CAE LA PRESION INTERNA.
