    • A semi rigid container comprising a plurality of generally rectangular side walls and a bottom wall attached to the bottom of each side wall. A plurality of flexible supporting frames are attached to each side wall to expand the container's open top and to brace the side walls into a free standing container for handy storage, transportation or disposal of refuse or other articles. A drawstring is provided along the top of the container for easy closure. The semi rigid container is made by attaching the flexible supporting frames to one or more sheets of flexible material, layering the sheet or sheets, and sealing the open margins of the layered sheet or sheets corresponding to the container's sides and bottom. The semi rigid container can be easily collapsed into a stack of side walls, then coiled into three adjacent loops and inserted into a storing receptacle.
    • 一种半刚性容器,其包括多个大致矩形的侧壁和附接到每个侧壁的底部的底壁。 多个柔性支撑框架连接到每个侧壁以扩大容器的敞开的顶部并且将侧壁支撑到独立的容器中,以方便地存储,运输或处理垃圾或其它物品。 沿着容器的顶部提供束带,以便于封闭。 半刚性容器通过将柔性支撑框架附接到一个或多个柔性材料片材上,层压片材或片材,并且密封与容器的侧面和底部相对应的层状片材的开口边缘而制成。 半刚性容器可以容易地折叠成一叠侧壁,然后卷成三个相邻的环并插入存储容器中。
