COLLAPSIBLE SELF-EXPANDING LIQUID CONTAINER

摘要

A liquid container for capturing liquid hazardous materials, the container comprising a bottom (11), preferably circular, and a generally vertical wall (12), preferably annular or conical, attached to the perimeter of the bottom to form a container with a large open top. The bottom and wall are composed of a flexible, liquid impermeable material, preferably a material that is also chemical resistant and wear resistant. The container may further comprise a liner. The top of the wall incorporates a semi-rigid floating member (15) which completely encircles the opening, the floating member being collapsible or foldable for storage. The perimeter of the bottom incorporates a structural member (14) composed of a flexible, resilient material which provides rigidity to the perimeter and acts to spread the bottom to its maximum size. The frame member is collapsible on itself such that the device can be collapsed into a small size. The frame member is self-opening.
