    • A tamper evident bag having a non-reusable frangible fastener profile assembly comprising two sets of lockable fastener profile elements specially constructed to manually lock together without the use of tools, and which once locked cannot be forcibly pulled apart. The bag includes a frangible connector bridge which will break away when the bag is opened indicating that the bag has been tampered with. The construction of the fastener elements also assures proper alignment of the lockable fastener profile elements across the length of the upper portion of the bag wall panels, making interlocking closure easy when pressure is applied on the outer walls of the bag behind the fastener profile elements.
    • 具有不可重复使用的易碎紧固件轮廓组件的防拆包装袋包括两组可锁紧的紧固件轮廓元件,其特别构造为在不使用工具的情况下手动地锁定在一起,并且一旦被锁定就不能被强制拉开。 该袋子包括一个易碎的连接器桥,当袋子打开时它将脱落,表示袋子被篡改。 紧固件元件的结构还确保可锁定的紧固件轮廓元件在袋壁板的上部的长度上的正确对准,使得在紧固件轮廓元件后面的压力被施加在袋的外壁上时使互锁的关闭变得容易。

    • A reclosable bag has a bag body and a reclosable, zipper-type closure. The reclosable closure has extruded male and female interlocking profiles extending along opposing sides of an opening of the bag and are constructed to releasably interlock. The closure also has an extruded valve flange extending from one side of the closure to engage an opposing surface of the closure when the profiles are interlocked. The flange and opposing surface are constructed to separate in response to pressure within the bag for venting the bag with the profiles interlocked, and to increase a contact pressure therebetween in response to presence of a vacuum in the bag. The closure also defines a vent passage extending from an air space between the opposing sides of the opening and between the interlocking profiles and the valve flange. In use, the interlocking profiles are engaged to close the bag opening, and then the bag sides are compressed together to force entrapped air out through the vent opening, deflecting the valve flange away from its opposing surface.
    • 可重新封闭的袋子具有袋体和可再闭合的拉链型封口。 可重新闭合的封闭件具有挤出的阳和阴互锁型材,其沿着袋的开口的相对侧延伸并且构造成可释放地互锁。 封闭件还具有从封闭件的一侧延伸的挤出阀凸缘,以在型材互锁时与封闭件的相对表面接合。 凸缘和相对表面被构造成响应于袋内的压力而分离,以便使配合物互锁的袋子排出,并且响应于袋中存在真空而增加其间的接触压力。 封闭件还限定了从开口的相对侧之间和互锁型材与阀凸缘之间的空气空间延伸的通气通道。 在使用中,互锁型材被接合以闭合袋开口,然后袋侧面被压缩在一起以迫使截留的空气通过排气口排出,使阀凸缘偏离其相对的表面。

    • Closure arrangements for use with flexible packages include a zipper-type closure, which, after initial sealing, if access is gained to a package interior, the arrangements provide evidence of that access. In certain embodiments, a closure with mating male and female profiles is used which, after initial sealing of the package, if access is desired to the package interior, one of the male or female profiles breaks, to prevent a resealing of the package. In other embodiments, after initial mating of the male and female closure profiles in order to seal the package, if access is desired to the package interior, the package walls are torn in order to gain access. In other embodiments, after initial sealing of the package by mating of the male and female profiles, if access is desired to the package interior, the male and female profiles are deformed, such that they no longer mate to provide a secure closure. Methods for using the arrangements herein are also provided.
    • 与柔性包装一起使用的关闭安排包括拉链式封闭件,其在初次密封之后,如果获得到包装内部的通道,则该布置提供了该通道的证据。 在某些实施例中,使用具有配合阳和阴型材的封闭件,其在封装的初始密封之后,如果需要对封装内部进行访问,则阳型或阴型型材中的一个断裂,以防止封装的再密封。 在其它实施例中,为了密封包装,在初次配合阳型和阴型封闭型材之后,如果需要对封装内部进行接近,则封装壁被撕裂以便进入。 在其他实施例中,在通过配合阳型和阴型轮廓来初始密封包装之后,如果需要对包装内部进行接近,则阳型和阴型型材变形,使得它们不再配合以提供安全的封闭。 还提供了使用本文中的装置的方法。
