Abstract

MEMBRANA DE CIERRE (11) PARA RECIPIENTES (10) QUE CONTIENEN UNA LAMINA EXTERIOR (16) Y UNA LAMINA INTERIOR (15) Y UNA CAPA DE UNION (17) SITUADA ENTRE LAS DOS LAMINAS, Y UNA ZONA DE COSTURA DE SELLADO (13). DENTRO DE LA ZONA DE LA COSTURA DE SELLADO, ENTRE LA LAMINA EXTERIOR Y LA LAMINA INTERIOR, HAY POR LO MENOS UN ESPACIO INTERMEDIO (21) LIBRE DE LA CAPA DE UNION, Y DENTRO DE LOS LIMITES DEL ESPACIO INTERMEDIO EXENTO DE CAPA DE UNION, LA LAMINA EXTERIOR Y LA LAMINA INTERIOR PRESENTAN POR LO MENOS SENDOS ORIFICIOS (19, 20), Y EN EL ESPACIO INTERMEDIO LIBRE DE LA CAPA DE UNION, ENTRE LA LAMINA EXTERIOR Y LA LAMINA INTERIOR, ESTA SITUADA UNA CANTIDAD DE UN MATERIAL (18) QUE SE REBLANDECE CON EL CALOR. LOS ORIFICIOS DE LA LAMINA INTERIOR Y LOS ORIFICIO DE LA LAMINA EXTERIOR ESTAN EN UN PRINCIPIO COMUNICADOS ENTRE SI, PERMITIENDO EL PASO DE UN FLUIDO, TAL COMO GAS (19) DESDE EL INTERIOR DEL RECIPIENTE (23) A LA ATMOSFERA CIRCUNDANTE. CUANDO SE APLICA CALOR A LA MEMBRANA DE CIERRE, POR EJEMPLOMEDIANTE UN PROCESO DE ESTERILIZADO DEL RECIPIENTE DOTADO DE LA MEMBRANA DE CIERRE, SE CIERRAN LOS ORIFICIOS DE LA LAMINA INTERIOR Y DE LA LAMINA EXTERIOR AL REBLANDECERSE EL MATERIAL CON EL CALOR.
