Abstract

Patente de Invenção: "FECHAMENTO DE EXTREMIDADE COM CAPACIDADE DE ABERTURA MELHORADA". A presente invenção proporciona um fechamento de extremidade para um recipiente tendo uma parede de painel central com um painel de ruptura deslocável definido por um entalhe quebradiço com um segmento inclinado e um segmento de articulação não-quebradiço. Uma alça é presa na parede do painel por um rebite, a alça tendo uma ponta estendendo-se sobre uma porção do painel de ruptura, uma extremidade de levantamento oposta à ponta, e uma alma central com uma região de articulação e uma ilha de rebite circundando o rebite. Um rebordo é formado inteiramente em uma área exposta do painel central formado por uma região de vazio da alma. A invenção adicionalmente proporciona um entalhe com um primeiro segmento de linha de entalhe com uma região de saída e um segundo segmento de linha de entalhe curvilíneo estendendo-se do primeiro segmento para a porção de borda externa do painel. A ponta da alça tem uma borda externa em formato geralmente assimétrico com uma primeira porção e uma segunda porção, a segunda porção estendendo-se mais sobre o painel de ruptura para a zona de transição curvilínea do que a primeira porção da ponta. A invenção adicionalmente proporciona uma alça com uma espessura assimétrica, com uma porção engrossada ficando adjacente ao segundo segmento de linha de entalhe, e adicionalmente proporciona uma extremidade tendo um segmento de rebordo posicionado sob uma porção lateral da ponta da alça adjacente ao segundo segmento do entalhe. A presente invenção também proporciona uma extremidade com uma alça tendo um eixo longitudinal central e uma alma com uma região de articulação adaptada para curvar-se em uma linha de articulação quando uma força de levantamento é aplicada na extremidade de levantamento da alça para produzir uma força de alavanca pela ponta contra o painel de ruptura, a linha de articulação interceptando o eixo longitudinal central da alça em um ângulo oblíquo. A invenção também proporciona um perfil escalonado da borda externa do painel com um escareador tendo paredes substancialmente paralelas e uma parede de mandril estendendo-se, em maneira angular, de debaixo da altura do painel para a espiral.
