Abstract
Window/cassette cover combinations and more economical methods for assembling the window in the cassette are described. A planar window is: rectangular and includes a pair upper lips, each an opposite sides, and a pair of lower riges or ledges, each on other sides; generally square and includes an upper discontinuous lip and a pair of lower ridges or ledges on opposite sides; or circular and includes an upper continuous lip and a lower continuous ridge or ledge. In each of these three embodiments, the upper lips and lower ledges or ridges cooperate to receive the borders of a window opening formed in the cassette cover, and a label can be applied between the windows and optionally covering one or more windows. In each embodiment of the method, the window is flexed to position opposing ledges under the borders and the window is returned to its original planar position so that the upper lip abuts the top of the border. For each method, a label can be applied between the windows and covering one or more windows, and the above steps are reversed to remove the window.
