Abstract: A container for thin rigid envelopes, each of which is a solid and has length greater than width the thickness much less than width--such as the package for a compact disc record album--having connected lower and upper levels. The lower level defines transverse and longitudinal axes of the container as well as a number of cavities with upwardly-disposed open ends, and the upper level comprises an exterior retaining wall and opposed ledges extending at an angle from the wall. An envelope may be inserted, width-edge down, into and held in one of the cavities; alternatively, such envelope may be placed on the upper level, length-wise on its lower edge and transverse the longitudinal axis of the container, with its lower corners supported, respectively, by the ledges. A spacer may be inserted into a cavity to separate the envelopes into distinct organizational groupings.
