Abstract
Abstract A unitary blank and a curriculum container assembly for enhousing in combination a rectangular tray of diapositives and a tape cassette. The container assembly includes generally rectangular top, bottom, and first and second side wall elements forming a rectangular cylinder. One end of the cylinder is closed with an end wall and the other end of the cylinder is provided with an access end wall flap pivotally attached to the bottom panel and an access end wall pivotally connected to the top panel. First and second generally rectangular interior side walls are connected to the bottom panel and are provided with sculptured recesses in the edges thereof adjacent the access end of the container assembly for providing ready access to a tray of diapositives and a tape cassette enhoused within the container assembly. A partition may be inserted within the outer container assembly which includes a generally rectangular wall element which extends in a coextensive and mutually parallel posture with respect to the first and second interior wall elements, and in like manner is provided with a sculptured recess at the access end to facilitate removal of a rectangular tray of diapositives or a tape cassette positioned within the container assembly. Access to the tape cassette is further facilitated by the provision of a tab normally extending with respect to the generally rectangular partition wall element and being operably positioned thereupon to maintain the tape cassette in a convenient removal posture at the access end of the curriculum container assembly.

first and second generally rectangular interior side panels having a first pair of opposing edges and a second pair of opposing edges longer than said first pair of opposing edges, one of said second pair of oppoSing edges of each of said first and second interior side panels being connected coextensively to respective ones of said second pair of edges of said bottom panel element, said first and second interior side panels extending in a mutually parallel planar posture with said first and second exterior side panels; a sculptured recess formed in each of said first and second generally rectangular interior side panels within the edge of said first pair of opposing edges of each of said first and second generally rectangular interior side panels adjacent said access end wall flap, for providing access to a rectangular tray of diapositives and a tape cassette positioned within said curriculum container assembly; means for maintaining said rectangular top panel element, said first and second rectangular exterior side panels, said rectangular access end wall, said closed end wall panel, said rectangular bottom panel, said generally rectangular access end wall flap and said first and second generally rectangular interior side panels in the previously recited structural postures for forming a generally hollow rectangular box suitable to enhouse a rectangular tray of diapositives in combination with a tape cassette and for providing ready access thereto by flipping up said access end wall pivoted about said hinge means extending transversely across said top panel element and flipping down said access end wall flap; and, insert means operable to be positioned within the interior of said curriculum container assembly for separating a rectangular tray of diapositives and a tape cassette and for maintaining the cassette tape in a posture for ready removal at the access end of said container assembly, said insert means comprising: a rectangular base panel having a first pair of opposed edges and a second pair of opposed edges longer than said first pair of opposing edges, said base panel being operable to overlay said bottom panel element of said container assembly and further being operable to be connected to said bottom panel element; a generally rectangular partition panel having a first pair of opposing edges and a second pair of opposing edges longer than said first pair of opposing edges, one of said second pair of edges being connected to one of said second pair of opposing edges of said rectangular base panel, said partition panel projecting in a posture perpendicular to said insert rectangular base panel; tab means connected to a lateral surface of said partition panel and extending normally therefrom for forming a stop abutment for a tape cassette to maintain the cassette in a posture for ready removal at the access end of said container assembly; and, a sculptured recess formed within one of said first pair of opposed edges of said generally rectangular partition panel, positioned adjacent the access end of said container assembly for providing access to a rectangular tray of diapositives and a tape cassette positioned within said container assembly.
