A carrying case adapted to conveniently contain writing materials. A carrying case has a lower portion having inwardly facing surfaces that define an upwardly opening file chamber having a lower portion rim. An upper portion has inwardly facing surfaces that define a storage chamber having an upper portion rim. A panel is adapted to move between a closed position and an open position to selectively close and open the storage chamber. Means are provided for removably fastening the upper portion rim to the lower portion rim to thereby close the file chamber.

1. A carrying case adapted to conveniently contain writing materials comprising: (a) a lower portion having inwardly facing surfaces that define an upwardly opening file chamber having a lower portion rim; (b) an upper portion having inwardly facing surfaces that define a storage chamber having an upper portion rim; (c) a panel and means for sliding the panel between a closed position and an open position to selectively close and open the storage chamber; and (d) means for removably fastening the upper portion rim to the lower portion rim only when the panel is in its closed position to thereby close the file chamber and constrain the panel within its closed position. 2. The carrying case of claim 1 wherein the means for removably fastening permits removal of the upper portion from the lower portion. 3. The carrying case of claim 1 wherein the lower portion has generally opposed lower portion ends and the upper portion has a roof and upper portion opposed ends and opposed sides, inwardly facing surfaces of the upper portion roof, ends, and sides defining the storage chamber and the upper portion ends and sides terminating to define the upper portion rim at a point remote from the roof, the upper portion also including a raised tongue extending from the upper portion rim in a direction away from the roof, the tongue having a size selected to extend within the file chamber when the upper and lower portion rims are placed adjacent to each other to locate the upper portion on the lower portion, the tongue having opposed tongue sides and ends adjacent respectively to the upper portion sides and ends, the tongue ends having a ridge extending endwardly generally parallel to the upper portion rim, the interior surface of each lower portion end including an indentation having a size and location so selected that a ridge of the upper portion fits therein when the upper and lower portion rims are placed adjacent to each other to retain the upper portion on the lower portion. 4. The carrying case of claim 3 wherein inwardly facing surfaces of each tongue side define panel slots extending parallel to the upper portion rim for substantially the length of the tongue side and at least one tongue end has a panel opening aligned with the panel slots and extending parallel to the upper portion rim, the panel slots and panel opening having a size selected to be sufficient that the panel can readily slide therethrough. 5. The carrying case of claim 4 wherein each tongue end includes a panel opening, and the panel has a size selected to be such that, with the panel in the closed position, the tongue may extend within the file chamber when the upper and lower portion rims are placed adjacent to each other with inwardly facing surfaces of the file chamber so confining the panel as to prevents its moving endwardly from its closed position. 6. The carrying case of claim 5 wherein the panel has a panel handle fastened thereto and having a size such that the panel handle contacts the tongue end through which the panel extends when the panel is moved to its open position so as to prevent the panel from being entirely removed from the upper portion and, when the panel is in its closed position, contacts the other tongue end to prevent movement of the panel beyond its closed position. 7. The carrying case of claim 5 wherein the upper portion is bilaterally symmetrical about a plane extending through the upper portion ends generally parallel to the upper portion sides to define identical front and back upper portion halves, whereupon the upper portion may be conveniently made from identical upper portion halves manufactured from a moldable material in a single mold. 8. The carrying case of claim 1 wherein the lower portion has two lower portion ends and two lower portion sides, upwardly presenting portions of which combine to define the lower portion rim and inwardly facing surfaces thereof at least partly define the upwardly opening file chamber, the lower portion including file hangers protruding inwardly from the ends into the file chamber at a selected distance beneath the level of the lower portion rim, the distance between the file hangers of the lower portion ends being such that selected hanging files may be suspended therefrom. 9. The carrying case of claim 8 adapted to contain hanging files depending from downwardly presenting side hooks located at each upper corner of the hanging file, the side hooks having downwardly extending projections, each file hanger of the carrying case having an upwardly opening trough adapted to receive the downwardly extending projections to help retain the side hooks in place on the file hangers. 10. The carrying case of claim 8 wherein the lower portion is bilaterally symmetrical about a plane extending through the lower portion ends substantially parallel to the lower portion sides to divide the lower portion into identical front and back lower portion halves, whereupon the lower portion may be made by combining identical front and back halves molded from a moldable material in a single mold. 11. The carrying case of claim 3 wherein the lower portion has two lower portion ends and two lower portion sides, upwardly presenting portions of which combine to define the lower portion rim and inwardly facing surfaces thereof at least partly define the upwardly opening file chamber, the lower portion including file hangers protruding inwardly from the ends into the file chamber at a selected distance beneath the level of the lower portion rim, the distance between the file hangers of the lower portion ends being such that selected hanging files may be suspended therefrom. 12. The carrying case of claim 11 adapted to contain hanging files depending from downwardly presenting side hooks located at each upper corner of the hanging file, the side hooks having downwardly extending projections, each file hanger of the carrying case having an upwardly opening trough adapted to receive the downwardly extending projections to help retain the side hooks in place on the file hangers. 13. The carrying case of claim 11 wherein the lower portion is bilaterally symmetrical about a plane extending through the lower portion ends substantially parallel to the lower portion sides to divide the lower portion into identical front and back lower portion halves, whereupon the lower portion may be made by combining identical front and back halves molded from a moldable material in a single mold. 14. The carrying case of claim 7 wherein the lower portion has two lower portion ends and two lower portion sides, upwardly presenting portions of which combine to define the lower portion rim and inwardly facing surfaces thereof at least partly define the upwardly opening file chamber, the lower portion including file hangers protruding inwardly from the ends into the file chamber at a selected distance beneath the level of the lower portion rim, the distance between the file hangers of the lower portion ends being such that selected hanging files may be suspended therefrom. 15. The carrying case of claim 14 adapted to contain hanging files depending from downwardly presenting side hooks located at each upper corner of the hanging file, the side hooks having downwardly extending projections, each file hanger of the carrying case having an upwardly opening trough adapted to receive the downwardly extending projections to help retain the side hooks in place on the file hangers. 16. The carrying case of claim 14 wherein the lower portion is bilaterally symmetrical about a plane extending through the lower portion ends substantially parallel to the lower portion sides to divide the lower portion into identical front and back lower portion halves, whereupon the lower portion may be made by combining identical front and back halves molded from a moldable material in a single mold.
