A container for retaining bulk materials for storage and/or transport. The container includes improvements over existing collapsible containers designed for the same purpose. The container of the present invention includes an impervious liner for receiving and retaining within the container bulk materials for which contact with reactive fluids is undesirable. Such bulk materials include, but are not limited to, spent catalysts. The impervious liner is preferably made of a material such as a polypropylene/nylon/polypropylene blend. An additional feature of the present invention is a weather-blocking cover that is adapted to be connected to the walls of a bulk container that may or may not be collapsible. The weather-blocking cover is adapted to seal off upper surfaces and edges of the container so that the container may be stored externally for extended periods without fear that precipitation will seep into the interior of the container.
