  • Patent number: 5029699
    Abstract: A container has a self-sustaining housing filled with a first sorbent body of compressed polyolefin microfibers, which body is formed with at least one pocket that snugly receives a vessel holding hazardous materials. The container is closed by a lid which is filled with a second sorbent body of compressed polyolefin microfibers, and when the lid is in place, the second body presses against the vessel to hold it snugly in place. At least a portion of the first sorbent body has a solidity of less than 20%, making it highly sorbent of liquids so that it can sorb any liquid that might leak from the vessel and thus help to prevent the liquid from escaping from the container.

The polyolefin microfibers preferably are particles, and the particles preferably are microwebs produced by divellicating a polyolefin microfiber web. When the container is used to transport sorbent materials that have been saturated by liquids of a chemical spill, the sorbent body ensures against there being any free liquid in the container.
