摘要： A vacuum indicating closure for a container for the packaging of a vacuum-packed product, the closure being of two-piece construction and having a metal lid portion which is retained in sealing engagement with the rim of a container by a plastic ring portion. The metal lid portion has a vacuum indicating button centered therein, which vacuum indicating button can flex downwardly from its normal position into the headspace of a container under the influence a sub-atmospheric or negative pressure in the headspace. The ring portion of the closure has a radially inwardly projecting annular flange at the top thereof to urge a peripheral portion of the lid portion of the closure against the rim of the container, the ring portion of the container further having a radially inwardly projecting annular bead to lock the lid portion of the closure against the underside of the annular flange of the ring portion so that the lid portion and the ring portion can be conveniently handled in unison. The ring of the closure further has an annular skirt with radially inwardly projecting ribs thereon, whereby the closure can be mechanically attached to a helical threaded container finish by a push-on action, the ribs being deformable under compressive loadings by the helical thread on the container finish to deform and thereby ensure that the closure under normal circumstances can be removed from the container by an unscrewing motion.
摘要翻译：用于包装真空包装产品的容器的真空指示封闭件，封闭件是两件式结构，并且具有金属盖部分，该金属盖部分通过塑料环部分与容器的边缘保持密封接合。金属盖部分具有以其为中心的真空指示按钮，该真空指示按钮可在其顶部空间中的低于大气压或负压的影响下从其正常位置向下弯曲到容器的顶部空间。闭合件的环部分在其顶部具有径向向内突出的环形凸缘，以将盖的盖部分的周边部分推靠在容器的边缘上，容器的环部分还具有径向向内突出的环形凸缘将盖的盖部分锁定在环部分的环形凸缘的下侧，使得盖部分和环部分可以方便地一起处理。封闭件的环还具有环形裙部，在其上具有径向向内突出的肋，由此通过推动作用将封闭件机械地连接到螺旋状的容器端部，肋可以在螺旋形螺纹的压缩载荷下变形容器整理变形，从而确保通常情况下的关闭可以通过旋松运动从容器中移除。

摘要： A tamper indicating package comprising a container having a neck with external threads formed thereon and a plastic closure comprising a top panel and an integral depending annular skirt. The skirt has integral internal threads formed thereon complementary to the threads on the neck of the container. The container has an annular locking bead positioned axially below the threads, and the skirt has a ring at the lower end thereof connected to the upper portion of the skirt by a plurality of circumferentially spaced integral bridge portions located below the threads when the closure is on the container. The ring has a radially inwardly extending annular rib engaging beneath the locking bead of the container when the closure is on the container. The skirt has an annular groove formed therein in the area of the bridge portions, the groove being formed after molding by deforming an annular portion of the skirt thereby displacing material in the annular area axially and stressing the material in the annular area.
摘要翻译：一种防拆指示包，其包括具有形成在其上的外螺纹的颈部的容器和包括顶板和整体悬垂的环形裙部的塑料封盖。裙部具有形成在其上的整体内螺纹，其与容器的颈部上的螺纹互补。容器具有轴向位于螺纹下方的环形锁定珠，并且裙部在其下端处具有连接到裙部的上部的环，当封闭件打开时，多个周向间隔开的整体桥接部分位于线下方。容器当封闭件在容器上时，环具有在容器的锁定凸缘下方的径向向内延伸的环形肋。裙部在桥接部分的区域中具有形成在其中的环形槽，凹槽通过使裙部的环形部分变形而在模制之后形成，从而轴向地移动环形区域中的材料并且在环形区域中施加材料。
