1 Claim, 8 Drawing Figures PATENTEB JAN 7 I975 SHEET 10F 2 PATENTEUJIW' ms SHEET 2 BF 2 M WWW HGT CURRICULUM CONTAINER ASSEMBLY BACKGROUND OF THE INVENTION The invention pertains to a curriculum container assembly for enhousing a rectangular tray of diapositives in combination with a tape cassette.

Contemporary educational techniques have advanced a great deal from the one room school houses prevalent as late as the early l900s. Notwithstanding, however, general advances, the traditional teaching technique of utilizing an instructor/lecturer for presenting material to a classroom of individuals possessing a wide variety of interests and capabilities remains as a significant learning impediment. Individualized instruction is a solution to the problem of boring some students while advancing too rapidly for others. However, as a practical matter, private tutors are available only for the wealthy.

In the relatively recent past an audio-visual-tutorial system has been developed to accommodate definable learning objectives of students with diverse educational backgrounds and capabilities. The system features individualized instruction tailored to individual learning speeds, styles and capabilities which may be utilized at the convenience of the student.

More specifically, the audio-visual-tutorial system comprises .an individual learning carrel or console equipped with a cassette tape player, earphones and a slide projector. In the privacy of a carrel a student takes a complete course, progressing unit-by-unit through a series of carefully programmed lessons, each within its own clearly stated behavioral objective. Lessons consist of tape/slide presentations together with written materials which guide the students through practice exercises, lab assignments and selective reference work.

In order, however, to most effectively utilize the foregoing described audio-visual-tutorial system it is necessary to provide the capability for large numbers of students to select and utilize, at will, a wide variety of program materials. In this connection a tray of diapositives and a corresponding tape cassette, have, in the past, been combined in a top opening cigar type box. A plurality of these boxes have been maintained on shelves in a central location adjacent a plurality of individual learning carrels. While such cigar type container assemblies have provided a degree of utility in maintaining the integrity of individualized program materials, room for significant improvement remains.

In this connection it would be highly desirable to provide a container assembly which is compact for easy storage, and provides ready shelf access, while being highly rugged in construction for maintaining its shape during prolonged use by a number of individual students. Further, it would be highly desirable to provide a container assembly which will facilitate access to a rectangular tray of diapositives amd a compatible tape cassette for minimizing handling difficulties in connection with retrieving and replacing the tray and cassette without damaging a photo negative or tape during the handling process. Still further it would be desirable to provide a container assembly which would be sufficiently rugged to protect the contents in the event the program materials are accidentally dropped by a student user.

It is therefore a general object of the invention to provide a novel curriculum container assembly which will obviate or minimize problems of the type previously described.

It is a specific object of the invention to provide a novel curriculum container assembly which is compact in design for minimizing the shelf space required for storing the assembly.

It is a further object of the invention to provide a novel curriculum container assembly which is highly rugged in design and construction to protect a rectangular tray of diapositives and a tape cassette enhoused therein, and at the same time maintain the shape and configuration of the container assembly over prolonged periods of use.

It is yet a further object of the invention to provide a novel curriculum container assembly which is operable to provide ready access to a rectangular tray of diapositives and a tape cassette contained therein.

It is still another object of the invention to provide a novel curriculum container assembly wherein intrinsically induced techniques for tape cassette and slide tray removal minimizes the possibility of a student damaging the diapositives or magnetic tape.

It is yet still another object of the invention to provide a novel curriculum container assembly wherein the structural elements of the container assembly per se are dimensioned to provide a bias tending to maintain the container assembly in a closed posture.

It is another object of the invention to provide a novel container assembly wherein a rectangular tray of diapositives and a smaller tape cassette both may be maintained at a convenient removal posture at an access end of the container assembly.

It is yet another object of the invention to provide a novel curriculum container assembly wherein the external structural integrity of the assembly is maintained without the utilization of an adhesive such as glue or the like.

It is still another object of the invention to provide a novel curriculum container assembly wherein the structural integrity of the exterior container is maintained with a minimum number of connecting means.

It is yet still another object of the invention to provide a novel unitary blank operable to form a curriculum container assembly operable to minimize the amount of stock material needed to form the container.

It is a further object of the invention to provide a novel unitary blank operable to form a curriculum container assembly by bending and folding an appropriately creased, scored and cut-out unitary piece of material, into a completely enclosed curriculum container assembly utilizing a minimum number of connecting means to maintain the exterior configuration of the container assembly.

These and many other objects and advantages of the present invention will become apparent from the claims and from the following detailed description of a preferred embodiment of the invention taken in conjunction with the accompanying drawings.

FIG. 6 is an axonometric projection of a partition operably positionable within the interior of the curriculum container assembly for separating a tray of diapositives and a tape cassette positioned within the container assembly and for maintaining the tape cassette in a convenient removal posture at an access end of the curriculum container assembly;

DETAILED DESCRIPTION Turning now to the drawings and particularly to FIGS. 1 and 2 thereof there will be seen a curriculum container assembly 10 according to a preferred embodiment of the invention.

More specifically the curriculum container assembly 10 is specifically designed to enhouse a rectangular tray 12 of the type suitable to carry a plurality of diapositives which may be utilized with an automatic interchange projector. Further, the container assembly enhouses a standard size tape cassette 14 which may be utilized to advantage in connection with diapositives carried by the rectangular tray 12 in an audio-visualtutorial system as previously discussed.

With reference now particularly to FIGS. 1, 2 and 8, the specific structure of the curriculum container assembly 10 may be seen. In this connection the curriculum container assembly 10 includes a rectangular top panel element 16 having a pair of opposing edges 18 and 20 and a second pair of opposing edges 22 and 24 which are longer than edges 18 and 20. The top panel element 16 is provided with a double crease hinge 26 which transversely extends between the second pair of edges 22 and 24 in a posture closer to the edge 18 than the other edge 20.

Directly connected to the rectangular top panel element 16 along fold lines 28 and 30 are first and second exterior side panels 32 and 34, respectively.

The side panel 32 is formed with a rectangular configuration and includes a first pair of opposing edges 36 and 38 and a second pair of opposing edges 40 and 42. A cut line 44 extends, from one of the second pair of opposing edges of the rectangular side panel 32 at the location of the transverse hinge 26, slopingly outwardly to the other edge 40 of the side panel in a direction toward one edge 36 of the first pair of opposing edges. In a similar manner, the exterior rectangular side panel 34 is provided with a first pair of opposing edges 46 and 48 and a second pair of longer opposing edges 50 and 52. A cut line 54 extends through the side panel 34 from a position on one edge 32 of the second pair of opposing edges at a location adjacent an end of the top panel hinge 26 in a sloping posture to the other edge 50 of the side panel in a general direction toward the edge 46 of the first pair of opposing edges of the exterior side panel 34.

The first and second rectangular exterior side panels 32 and 34 are provided along fold lines 56 and 58 with first and second rectangular end panels 60 and 62, respectively.

The container assembly 10 is further provided with a rectangular access end wall 64 having a first pair of opposing edges 66 and 68 and a second pair of opposing edges 70 and 72. One edge 66 of the first pair of opposing edges of the rectangular access end wall 64 is directly connected to one edge 18 of the first pair of opposing edges of the top panel element 16 along a coextensive fold line 74.

A rectangular closed end wall panel 76 is provided having a first pair of opposing edges 78 and 80 and a second pair of opposing edges 82 and 84. One edge 78 of the first pair of opposing edges of the end wall panel 76 is connected to the other edge 20 of the first pair of opposing edges of the rectangular top panel element 16 along a coextensive fold line 86.

The curriculum container assembly is further fashioned with a rectangular bottom panel element 88 having a first pair of opposing edges 90 and 92 and a second longer pair of opposing edges 94 and 96. The edge 90 of the first pair of opposing edges of the bottom panel element 88 is directly connected to the other edge 80 of the first pair of opposing edges of the rectangular closed end wall panel 76 along a coextensive fold line 98.

A generally rectangular access end wall flap is provided having a first pair of opposing edges 102 and 104, and a second pair of opposing edges 106 and 108. One edge 102 of the first pair of opposing edges of the generally rectangular access end wall flap 100 is directly connected to the other edge 92 of the first pair of opposing edges of the bottom panel element 88 along a coextensive fold line 110.

The curriculum container assembly is further fashioned with first and second generally rectangular interior side panels 112 and 114.

The first interior side panel 112 is provided with a first pair of opposing edges 116 and 118 and a longer second pair of opposing edges 120 and 122. One edge 122 of the second pair of opposing edges of the interior side panel 112 is connected directly to one edge 94 of the second pair of opposing edges of the bottom panel 88 along a score line 124 so that side panel 112 may be readily folded into a perpendicular posture with respect to the plane of bottom panel 88.

The second generally rectangular interior side panel 114 is provided with a first pair of opposing edges 126 and 128 and a second pair of longer opposing edges 130 and 132. One edge 132 of the second pair of opposing edges of the interior side panel 114 is connected directly to the other edge 96 of the second pair of opposing edges of the bottom panel element 88 along a score line 134 so that side panel 114 may be raised to a perpendicular posture with respect to the plane of the bottom panel element 88.

The first and second generally rectangular interior side panels 112 and 114 are fashioned with sculptured recesses 136 and 138 within the first pair of opposing edges 116 and 126 thereof adjacent to the access end wall flap 100.

Turning now specifically to FIGS. 3-5, it will be seen that the curriculum container assembly 10, in an assembled posture, comprises a top wall 16 and perpendicularly downwardly extending exterior side walls 32 and 34, and perpendicularly downwardly extending end walls 64 and 76. The end walls 64 and 76 are fashioned to be in parallel planes and normal to the parallel planes of the edge walls 32 and 34. In a similar manner the end walls 64 and 76, as well as the exterior side walls 32 and 34 are all perpendicular to the rectangular bottom panel element 88 which in turn is coextensive with and in a plane parallel with the plane of the rectangular top panel element 16.

Once the container assembly is folded into a solid rectangular posture, its shape may be ruggedly maintained by a minimum number of connecting elements. The connecting elements include a first pair of exteriorly mounted right angle edge strips 140 and 142 connecting the edges 36 and 70 of the first exterior side wall 32 and the access end wall 64 and the edges 46 and 72 of the second exterior side panel 34 and the access end wall 64 respectively. A second pair of exteriorly mounted right angle edge strips 144 and 146 connect the edges 40 and 94 of the first exterior side panel 32 and the bottom panel element-88 and the edges 50 and 96 of the second exterior side panel 34 and the bottom panel element 88 respectively.

The right angle edge strips may be formed with a plurality of designs and materials but a preferred design is illustrated and is composed of a metallic sheetmaterial having inwardly projecting teeth which project into the container wall elements to maintain, in a highly rugged and reliable manner, the solid rectangular exterior configuration of the curriculum container assembly. Moreover, while the edge strips, as discussed above, are preferred in some instances, gluing may be advantageously utilized with the addition of tabs on the liftable end wall.

In order to maintain the container assembly 10 in a closed posture, as depicted in FIG. 1, the dimensioning of the interior and exterior side wall panels in combination with the top and bottom panel elements is such that the access end wall flap 180 provides a slight bias outwardly on the interior surface of the access end wall 64.

In order to separate the tray of diapositives and the tape cassette to be positioned within the interior of the curriculum container assembly 10, a partition 150 is designed to be positioned within the interior of the container assembly as shown in FIGS. 3-7.

The partition or insert 150 includes a rectangular base panel 152 having a first pair of opposing edges 154 and 156 and a second pair of opposing edges 158 and 160 longer than the first pair of opposing edges. The base panel 152 of the insert 150 is operable to overlay and rest upon the base panel element 88 of the curriculum container assembly as shown in FIG. 4, and may be fixedly connected thereto with a suitable binder such as an adhesive or the like.

The insert 150 is further fashioned with a generally rectangular partition panel 162 having a first pair of opposing edges 164 and 166 and a second pair of opposing edges I68 and 170 longer than said first pair of opposing edges. One edge 170 of the second pair of opposing edges of the generally rectangular partition panel and one edge 160 of the second pair of opposing edges of the rectangular base panel of the partition are connected along a coextensive score line 172 as shown in FIG. 7. The score line 172 permits the partition 162 to be bent at a right angle with respect to the base panel 152.

A rectangular spacing ledge 174 may be connected along a score line 176 to the other edge 168 of the second pair of opposing edges of the partition 162. The spacing ledge 174 is dimensioned to cooperate with the dimensions of the first pair of edges 154 and 156 of the bottom panel 152 to extend across the interior of the curriculum container assembly and possess a combined dimension substantially equal to that of the first pair of edges and 92 of the base panel element 88.

A lateral face of the partition 162 is provided with a normally projecting tab 178 which projects from the partition in the same direction as the ledge 174. The tab 178 may be fashioned by stamping a U-shaped cut 180 through the partition 162 and forming on the tab a pair of fold lines 182 and 184 as shown in FIG. 7. The tab 178 may therefore be bent into a posture normally extending from the lateral face of the partition 162.

The placement of the tab 178 with respect to the first pair of edges 164 and 166 of the partition is designed so that a tape cassette 14 may be positioned in a posture abutting against the tab 178 as shown in FIG. 3, and extend to the access end of the curriculum container assembly in a posture which will facilitate removal of the tape cassette along with the larger dimensioned rectangular tray of diapositives 12.

Removal of the tape cassette is further facilitated by the provision of a sculptured recess 186 within one edge 166 of the first pair of edges of the partition 162. The sculptured recess 186 is operable in combination with the sculptured recess 138 to provide a ready access to the tape cassette 114 at the access end of the curriculum container assembly as shown in FIG. 2. Therefore a student user will inherently grab the outer tape cassette body rather than fouling or severing the tape exposed at the top of the cassette with a finger nail as is possible with the previously utilized top opening cigar box type of curriculum container assembly.

As previously discussed, the exterior structure of the curriculum container assembly is fabricated from the unitary blank of FIG. 8, which may be readily formed into a ruggedized container assembly for prolonged use. In this connection the interior side panels 112 and 114 are first upwardly folded about score lines 124 and 134, respectively. In a similar manner, exterior side panels 32 and 34 are pivoted upwardly about fold lines 28 and 30. The end tabs 60 and 62 are then folded inwardly and the bottom 88 and top panel elements 16 are folded together about fold lines 86 and 98 to form a solid rectangular structure such as illustrated in FIG. 1.

The metallic angle edge strips and 142 are then installed between the exterior side panels 32 and 34 and the access end wall 64. The exterior side panels 32 and 34 are then secured to the edges of the bottom panel 88 by metallic angle edge strips 144 and 146, thus completing the exterior structure of the curriculum container assembly.

A tray of diapositives and a companion tape cassette are then positioned upon opposite sides of a partition 162 of an insert 150. An adhesive may then be applied to the bottom panel 152 of the insert as desired, and the partition, tray of diapositives and tape cassette are inserted into the exterior shell of the curriculum container assembly to complete fabrication of the curriculum container assembly.

SUMMARY OF THE MAJOR ADVANTAGES OF THE INVENTION Viewed in the light of the foregoing it will be appreciated that the subject curriculum container assembly provides a means for enhousing a tray of diapositives in combination with a tape cassette which is compact in design to minimize shelf space and highly rugged for maintaining the shape of the container over a prolonged period of use.

The flip top end and the sculptured recesses in the side walls of the container assembly provide ready access to the ends of the slide tray and the tape cassette to facilitate removal and inherently induce proper handling of the tray and cassette to minimize the possibility of damage to the diapositives ormagnetic tape.

Further, the access end wall flap provides an outward bias upon the interior surface of the access end wall to maintain the container assembly in a closed, attractive posture.

By the provision of the subject design a highly rugged container is provided without utilizing gluing and only a minimum number of connector assemblies.

The partition element of the subject container assembly structurally reinforces the exterior container and synergistically maintains a tape cassette at the recess end of the assembly to facilitate removal and use.

A still further significant advantage of the subject invention is the provision of a unitary bland which may be stamped from a sheet of stock with a minimum amount of waste and which may be readily folded into a complete, highly rugged container assembly.

Although the invention has been described with reference to preferred embodiments, it will be appreciated by those skilled in the art that additions, modifications, substitutions, deletions and other changes not specifically described may be made which will fall within the purview of the appended claims.
