Abstract
Containers for storing and/or transporting sulfur-containing compounds, and methods of deodorizing headspace gases containing sulfur-containing compounds, are disclosed. The containers include a body and a lid. In one embodiment, copper or another sulfur-deodorizing substance is attached to either the lid or upper sides of the container or is suspended in the headspace. The sulfur-deodorizing substance reacts with or adsorbs or absorbs any sulfur-containing compounds present in the headspace volume to reduce the odor in the headspace. In another embodiment, when the container include a solid or viscous liquid sulfur-containing compound, a pouch containing a sulfur-deodorizing substance is placed on top of the sulfur-containing compound. The pouch includes a liner or a sealed side in immediate contact with the solid or viscous liquid sulfur-containing compound, and a non-contacting portion providing a breathable, porous construction to permit the headspace gases to come into contact with the sulfur-deodorizing substance.
