Abstract: A container is provided for use in a clean environment, thereby allowing functional access to items such as chemicals stored within the container while minimizing contamination to the clean environment. A two-part unitary door includes an access plug and an entry plug. The plugs are separable from one another so that the container may be moved freely within the clean environment while the access plug seals the container from exposure to the clean environment, and the entry plug seals the clean environment from the exterior contaminated area. Structure is provided to enable functional access to the items stored within the container. In other embodiments, containers are provided for such objects as computers, oscilloscopes and the like.
