    • A close nesting, single element, easy-opening tamper-proof closure for wide-mouth containers, especially externally beaded, round, nestable cup-like containers formed from paper or plastic, the closure comprising a central panel adapted to substantially span the mouth of the associated container and formed from paper, a non-shrinkable plastic material, or the like, and further comprising a frusto-conically shaped skirt formed from a double-ended blank of a plastic material which is highly oriented in the direction extending circumferentially of the closure, the overlapped ends of the blank being heat sealed or otherwise joined to one another inwardly of the outermost of the ends thereof, the inner smaller diameter of the skirt being adhesively joined to the outer periphery of the central panel, the skirt being shrinkable, upon the application of heat thereto when the closure is in place over the mouth of a filled container, to shrink into tight engagement with the mouth of the container, the outermost free end of the closure skirt serving as a pull tab by which the skirt may be conveniently separated from the panel when it is desired to open the container and to give a clearly visual indication that the container has been opened upon the first opening thereof. Such a closure may be provided in either flush-style or plug-style embodiments.
    • 用于广口容器,特别是从纸或塑料形成的外部串联,圆形,可嵌套的杯形容器的紧密嵌套,单元件,易开启的防拆封闭件,封闭件包括适于基本跨越 相关联的容器并且由纸形成,不可收缩的塑料材料等,并且还包括由塑料材料的双端坯料形成的截头圆锥形裙部,该塑料材料沿着沿圆周方向延伸的方向高度取向 封盖,坯料的重叠端部被热密封或以其它方式在其端部的最外侧彼此连接,裙部的较小直径粘合地连接到中心板的外周边,裙部可收缩, 当封闭件在填充容器的口部上的位置施加热量时,缩小成与容器的口部紧密接合 r,闭合裙部的最外侧的自由端用作拉片,当需要打开容器时裙部可以方便地从面板上分离,并给出清楚的视觉指示,即容器已经在第一 打开它。 这样的封闭件可以以冲压式或插头式实施例提供。

    • Improvements in closuring a container with a sheet of biaxially oriented thermoplastic resin by shrinking a portion of the sheet overlying the container mouth to tightly mechanically engage portions of the sheet which had been previously crimped under a peripheral lip on the container. The container, which may be of the thin walled variety, is supported by a holder during closuring in the vicinity of the peripheral lip to minimize the vertical load applied thereto.
    • 通过收缩覆盖在容器口部上的片材的一部分来紧密地机械地接合预先卷曲在容器上的周边唇缘的片材的部分,从而使用双轴取向的热塑性树脂片封闭容器的改进。 可以是薄壁品种的容器在闭合周围唇缘附近时由支架支撑,以最小化施加到其上的垂直载荷。
