Abstract

composições farmacêuticas e sistemas de entrega intravítrea de fármacos para o tratamento de doenças oculares. o objetivo da presente invenção é suprimir a adesão de um elemento intrusivo perto de uma seção de encaixe de uma rolha e evitar que uma região de ponta da rolha rache ou deslamine devido à falta de resistência. para alcançar o acima exposto, a presente invenção provê uma rolha 1 para lingotamento contínuo que compreende uma cavidade 11 para distribuição de gás no centro da mesma na direção vertical, em que: a rolha possui um material refratário poroso 12, que é permeável a gases, e um material refratário 13, que tem uma resistência maior que o material refratário poroso 12, disposto em um lado de superfície periférica externa e em um lado de superfície periférica interna, respectivamente, de pelo menos uma porção de uma seção transversal vertical de uma região lateral da ponta c.
