    • A packaging container having a pressure equalizing or venting valve which includes a valve seat, a pair of opposed faces and a valve opening therebetween. One of the faces is adapted to be secured to a wall of the packaging container surrounding an aperture which is located therein. A flexible valve diaphragm at least partially surrounds and substantially covers the valve opening on the other side of the faces and of the valve seat. A separation layer is secured to at least a portion of one of the faces of the valve seat and at least partially surrounds the valve opening. The separation layer is positioned between the other face and the flexible valve diaphragm to establish a pressure equalizing or venting passage extending from the valve opening through the flexible valve diaphragm.
    • 一种具有压力平衡阀或排气阀的包装容器,其包括阀座,一对相对面和其间的阀开口。 其中一个面适于固定在围绕位于其中的孔的包装容器的壁上。 柔性阀膜片至少部分地围绕并基本上覆盖在面部和阀座的另一侧上的阀开口。 分离层被固定到阀座的一个面的至少一部分上,并且至少部分地围绕阀开口。 分离层位于另一面和柔性阀膜之间,以建立从阀开口通过柔性阀膜延伸的压力平衡或通气通道。

    • This disclosure relates to a vent valve arrangement for a sealed package wherein when excessive pressures occur within the sealed package, gases will automatically be vented therefrom. The vent valve includes at least one perforation in the package with the perforation being formed through one of two walls of the package into the interior thereof and there being a resistance path from the interior of the package to the perforation with the resistance path being openable by forces expanding the walls whereby pressure that is caused by the formation of gases and vapors within the package will open the resistance path and escape through the perforation.
    • 本公开涉及一种用于密封包装的排气阀装置,其中当密封包装内发生过大压力时,气体将自动从其中排出。 排气阀包括在包装中的至少一个穿孔,穿孔通过包装的两个壁中的一个形成在其内部,并且存在从包装内部到穿孔的阻力路径,其中电阻路径可由 力的作用使壁膨胀,由此在包装内形成气体和蒸汽所产生的压力将打开阻力通道并穿过穿孔。

    • The carton and package provide a heat-releasable connection for a closure for a package which is to be heated for use wherein the heat sealed connection will become ineffective when subjected to boiling water conditions. In one form, the closure is a lid for a tray type container. In the second form the closure is a small closure for a small aperture in the lid wherein the size of the aperture is such that it will act as a one-way valve when the package is heated underneath the surface of the water to allow escape of steam or vapor under pressure and to prevent the ingress of water.
    • 纸箱和包装为用于要加热的包装的封闭件提供可热释放的连接,其中当经受沸水条件时,热密封连接将变得无效。 在一种形式中,封闭件是托盘型容器的盖子。 在第二形式中,封闭件是用于盖子中的小孔的小封闭件,其中孔的尺寸使得当包装被加热到水表面下方时,其将用作单向阀,以允许 蒸汽或蒸汽在压力下,并防止水进入。
