    • The disclosure relates to a waste bin having an inner steel container for refuse and an outer thermoplastic hood form cover having a domed top wall and side ports through which refuse may be deposited in the container. A lid for the container is mounted on the underside of the top wall of the cover and is supported on a central stud extending through the cover by means of a polythene washer held on the stud by a nut. If a fire should develop in the container the resulting heat will cause the washer to melt releasing the cover to fall onto the top of the container therefore preventing air flow into the container to restrict and extinguish the fire.
    • 本公开涉及具有用于垃圾的内钢容器的垃圾箱和具有圆顶顶壁和侧端口的外部热塑性罩盖形式盖,垃圾可通过该端口沉积在容器中。 用于容器的盖子安装在盖的顶壁的下侧上,并且通过由螺母保持在螺柱上的聚乙烯垫圈支撑在延伸穿过盖的中心柱上。 如果在容器内发生火灾,则所产生的热量将导致洗衣机熔化而释放盖子以落入容器的顶部,从而防止空气流入容器以限制和熄灭火。
