   First, by inserting the key insertion portion provided on the front surface of the lid portion of the box into the key difference receiving portion of the front front vertical portion, the lock is applied by the engagement of both members. That is, since the hooks provided on the left and right sides of the key insertion part are inserted from above into the hook receiver of the key insertion part, the lock is automatically applied. (See Figure 4)

   Next, to release the locked state, when a plate-like key plate is inserted between the key insertion portion and the key insertion receiving portion, the protrusions provided on the left and right sides of the lower end of the key plate are It inserts between the hook of a cover part and the hook receptacle of a key insertion part, and tries to isolate | separate both. As a result, the hook of the lid portion and the key receiving portion are opened, so that the key plate can be removed by pulling it upward. (See Figs. 6 and 7)

   If the lid is in the open state, the box contents can be taken out freely, and when returning this open state to the closed state again, the key insertion part of the lid part that was first performed should be the front vertical part. When inserted into the key receiving portion, both members are engaged again and become locked.

   The packaging box according to the present invention is made of corrugated cardboard with other paperboards pasted on both sides of corrugated paperboard, and the configuration and function of the lid opening / closing operation part in the packaging box of the product to be accommodated. It has characteristics.
