Abstract
Sr revela una tapa roscada (50) para recipientes presurizados, típicamente para bebidas carbonatadas. La tapa incluye un revestimiento deformable (15) de polímero no vinílico el cual es formado en frío en la tapa utilizando técnicas conocidas de modo que el revestimiento se une fisicamente a la superficie interna de la pared terminal de la tapa para ser retenido así en ausencia de un labio periférico o proyecciones en la superficie interna de la pared terminal de la tapa. La tapa en si misma puede ser moldeada por inyección o moldeada por comprensión. El anillo indicador de alteración usual (13) esta conformado para incluir elementos de travesaño frágiles (40) ya sea por moldeado o en una operación separada de corte. Las lenguetas montadas de manera pivotal (61) para separar el anillo indicador de alteración son suficientemente rígidas para evitar doblarse en puntos diferentes en un eje articulado de borde externo (60) donde solamente es posible pivotar en un grado limitado, asegurando así la ruptura de los elementos de travesaño frágiles en una etapa inicial cuando se abre la tapa.Sr reveals a screw cap (50) for pressurized containers, typically for carbonated beverages. The lid includes a deformable non-vinyl polymer liner (15) which is cold formed on the lid using known techniques so that the liner is physically attached to the inner surface of the lid end wall to be thus retained in the absence of a peripheral lip or projections on the inner surface of the end wall of the cap. The cap itself can be injection molded or compression molded. The usual tamper indicator ring (13) is shaped to include brittle cross member elements (40) either by molding or in a separate cutting operation. The pivotally mounted tabs (61) to separate the tamper indicator ring are stiff enough to avoid bending at different points on an outer rim jointed shaft (60) where it is only possible to pivot to a limited degree, thus ensuring breakage of fragile cross member elements at an early stage when the lid is opened.
