Abstract
Abstract A container for holding a plurality of cassettes in a stored environment such as an album. Each container is comprised of a flat wall portion, side walls, and a single end wall together with a preformed top wall. The cassette is inserted between the top wall and the bottom wall from an end portion. The top wall has a center portion displaced from the bottom wall a given amount sufficient to allow the cassette to enter freely. The bottom wall is substantially flat whereas opposing end portions of the top wall are spaced a greater distance from the bottom wall in the center portion and a distance sufficient to clear the extended flanges on the cassette that are in close proximity to the head portion. The pair of spaced-apart end portions on the top wall allow the cassette to be inserted in either direction and without restriction. An indentation located on the center line of the top wall and shaped in the form of an ellipse is located so as to fall within the wind or rewind gears of the cassette when located within the container. The elliptical portion of the indentation does not completely fill the hole of the wind or the rewind gear but only a portion of the opening and is the sole means of holding the cassette in the container.
