Storing and transporting flexible sheets

A container for storing a stack of substantially horizontal sheets on a substantially horizontal support, the container comprising a base being adapted to rest on the substantially horizontal support, a pair of upright sidewalls spaced from each other and secured to, a bottom wall, wherein the bottom wall is located adjacent to the base, an upwardly extending back wall disposed between the sidewalls, the front of the container being substantially open to facilitate loading sheets in the container with the sheets being generally horizontal to form a stack of sheets in the container, and to facilitate inspection of the stack for any contaminants in it, a separate inwardly extending retainer at the front edge of each side wall, the retainers extending toward each other so the horizontal distance between them is substantially uniform, each retainer having a horizontal dimension from front to back substantially less than that of the sidewalls, wheels mounted at bases of the container to rotate about a substantially horizontal axis adjacent the front of the container so the container can be tilted out of contact with the support and rolled on the wheels to transport the stack of sheets in the container, and a handle secured to an upper part of the front of the container to facilitate tilting the loaded container.
