<p>The present invention relates to a packing box equipped with an opening and closing door, which arranges a door fixating board, formed by cutting a part of a front board to open and close the inside of the packing box, on the front board of the packing box, and arranges the opening and closing door, guiding the door fixating board to be opened and closed and attaching and detaching the door fixating board to and from the front board, on the door fixating board. The opening and closing door gets closed on the front board while an attachment and detachment part goes into the inside of an upper cut line and is supported on an inner side of the front board if an upper part of the door fixating board is pushed, and gets released from the front board while the attachment and detachment gets out of the inner side of the front board if the front board at an upper side of the attachment and detachment part is pushed. Therefore the present invention closes the opening and closing door on the front board while being supported on the front board if the door fixating board is pushed and releases the door fixating board from the front board if the front door is pushed, thereby making it very convenient to open and close the packing box. Thus, the present invention makes it very convenient to open and close the opening and closing door installed in the packing box so it can conveniently close the opening and closing door all the time after withdrawing content out of the box and accordingly prevent an abnormal material such as a dust or the like from flowing into the packing box.</p> |
