Abstract

ESTRUCTURA DE CIERRE EXTREMO DE CHAPA METALICA PARA UN RECIPIENTE Y UN METODO PARA SU FABRICACION, EN DONDE SE ROMPE UNA PARTE CENTRAL DE UNA LINEA DE DEBILITAMIENTO POSTERIOR LEVANTANDO UN ABRIDOR DE LENGUETA (51) MIENTRAS SU EXTREMO DE TRABAJO ROMPE UNA PARTE PEQUEÑA DE UNA LINEA DE DEBILITAMIENTO PERIFERICA. EL MOVIMIENTO CONTINUADO DEL EXTREMO DE AGARRE DEL ABRIDOR HACIA UNA COSTURA (47) PRODUCE UNA ROTURA CONTINUADA DE DICHA LINEA PERIFERICA, ACTUANDO DICHA COSTURA COMO FULCRO DE PALANCA. EN EL DISCO RETIRABLE (31) Y EN LA PARTE DE LA ESTRUCTURA DE CIERRE QUE PERMANECE SUJETA AL RECIPIENTE SE FORMAN PLIEGUES PREVIOS MULTICAPA, PRODUCIENDO UN BORDE REDONDEADO DE PROTECCION DEL BORDE MELLADO RESIDUAL QUE QUEDA EN LA LINEA DE DEBILITAMIENTO. EL INVENTO ES APLICABLE A BOTES, TARROS Y SIMILARES.
