<p>PROBLEM TO BE SOLVED: To provide a document keeping box which enables the retrieval of documents to be easily performed with the realization of a short retrieval time and a simple and efficient take out/in operation and can be easily used with a simple structure without fear that a front door board may stand in the way of the retrieval, take in/out operation, and is suible for mass production and less costly, being easy to insert the tip part of a fitting strip piece into a strip piece insertion hole and detach the tip part from the insertion hole, ensuring keeping of an open part ion a closed state without greatly impairing the strength of the upper part of the front door board. SOLUTION: In a prefabricated document keeping box made of a suitable sheeting such as a corrugated fiberboard or the like, a box base SI with a front face open, and a front door board 10 is formed to the front edge of a bottom board 1 of the box base SI through a folding line 14. At the same time, a strip piece insertion hole 26 is perforated in the upper part away from the upper edge of the front door board 10 and a locking strip piece 20 is formed continuously to the top board 4 of the box base SI. Thus the open part of the box base SI is kept in a closed state by inserting the tip part of the fitting strip piece 20 into the strip piece insertion hole 26.</p> |
