Abstract

"TAMPA PLáSTICA, TAMPA FORMADA POR MATERIAL TERMOPLáSTICO E COM UMA SUPERFìCIE INTERIOR E UMA SUPERFìCIE EXTERIOR, E, MéTODO DE MOLDAGEM DE UMA TAMPA PLASTICA EJETáVEL POR DEFORMAçãO". é fornecida uma tampa plástica (10) com uma parte superior e uma saia (12) com uma superficie interior. Existem áreas fracas, áreas flexíveis (14), ou painéis flexiveis, preferivelmente, na superficie interior da saia (12), para permitir que a saia se expanda circunferencialmente de forma radial para fora, quando a superficie interior da saia (12) for submetida a uma força direcionada radialmente para fora, tal como durante o ejeção por deformação da tampa da ferramenta de moldagem (38). Um método de moldagem da tampa ejetável por deformação (10) inclui fornecer elementos que se estendem para fora (42) no macho (38) da ferramenta de moldagem para formar áreas (14) na tampa com espessuras menores do que a espessura média da tampa, para permitir que a tampa se expanda radialmente, quando a tampa for ejetada por deformação da ferramenta de moldagem (38) com mínimo dano na rosca."PLASTIC COVER, COVER FORMED BY THERMOPLASTIC MATERIAL WITH INTERIOR SURFACE AND EXTERIOR SURFACE, AND MOLDING METHOD OF A DEFORMABLE PLASTIC COVER". A plastic cover (10) with an upper part and a skirt (12) with an inner surface is provided. There are weak areas, flexible areas (14), or flexible panels, preferably on the inner surface of the skirt (12), to allow the skirt to radially outwardly expand when the inner surface of the skirt (12) is subjected. at a radially outwardly directed force such as during deformation ejection of the molding tool cover (38). A method of deformation ejectable cap molding (10) includes providing outwardly extending elements (42) in the mold tool die (38) to form areas (14) of the cap having thicknesses less than the average cap thickness. , to allow the cap to expand radially when the cap is ejected by deformation of the molding tool (38) with minimal thread damage.
