    摘要： A reclosable closure consists of two longitudinally continuous strips and which, when facially engaged, are held together by hook and loop fastening principles. The inner side of one strip has two fields of hook-engageable loops, separated by a female seal profile portion. The inner side of the other strip has two fields of molded hook elements arranged to engage the loops to hold the closure in its closed condition, and a central male seal profile portion for engaging the female seal profile portion to form a seal when the closure is closed. Another reclosable closure is held together by hook and loop fastening principles and includes a resilient bead that is compressed between opposing sides of the closure, or between spaced rails of an opposing side of the closure, when the hooks and loops of the closure are engaged. The closure is useful, for example, as a bag closure.

    摘要翻译： 可再闭合的闭合件由两个纵向连续的条带组成，并且当通过钩和环紧固原理将其表面接合时，它们被保持在一起。 一个条带的内侧具有两个可钩接合环的领域，由一个阴密封型材部分分开。 另一条带的内侧具有两个模制的钩状元件，两个区域被设置成接合环以将封闭件保持在其闭合状态;以及中央阳密封型材部分，用于在封闭件为闭合状态时接合阴密封型材部分以形成密封 关闭。 另一个可重新闭合的闭合件通过钩和环紧固原理保持在一起，并且包括当封闭件的钩和环接合时在弹性密封件的相对侧之间或在封闭件的相对侧的间隔的导轨之间被压缩的弹性珠。 封闭件例如用作袋封闭件是有用的。
