Semi-Prodcut for Document Storage Box Box for Document Storage and Packaging Method using it

摘要

The present invention relates to a semi-product for a document storage box, a document storage box using the same, and a manufacturing method thereof. To this end, according to the present invention, a rectangular upper plate is formed by using a folding as a boundary formed at an upper edge with respect to a rectangular rear plate for forming a rear part of a document storage box, and left, front and right plates are sequentially formed in a rectangular shape in the lateral direction of the rear plate by using each folding line as a boundary. A coupling wing is formed by using a folding line formed at an outer edge of the right plate as a boundary, a rectangular auxiliary bottom plate is formed by using the folding line formed at a lower edge with respect to the rear plate as a boundary, and rectangular auxiliary left and right plates are formed by using a folding line formed at both edges with respect to the bottom plate, respectively. The left and right plates have a grip hole formed at the lateral center by being spaced apart from the lower edge at a predetermined interval, and the auxiliary left and right plates have an auxiliary grip hole formed at the vertical center by being spaced apart from each inner edge at a predetermined interval. Accordingly, the bottom plate is formed between the auxiliary left and right plates, thereby providing an effect of smoothly distributing a load, which is concentrated on the bottom during a folding process when being folded to form a packaging box, to the left and right plates along the auxiliary left and right plates.
