  By the way, for example, when packaging a pouch filled with retort food or the like, the contents accumulate in the lower part of the pouch due to its own weight, and the pouch is in a swelled down state. When stored in a large space, a large gap is formed in the upper part of the packaging box.

  And if you store a plurality of such packaging boxes in an outer box and try to transport them to a retail store etc., a large outer box is required, and the occupied area and height in the state of being stacked on a pallet etc. will increase, There is a problem that transportation costs increase.

  As a countermeasure, it is conceivable to use a packaging box having a dormitory roof as described above. However, in such a packaging box, the roof part is constricted over the entire circumference of the trunk part. Due to the shape, irregular bellows-like ridges are formed on the upper part of the stored pouch, not only impairing the product value, but also due to the great resistance of the pouch when closing the roof, sealing is difficult become.

  Accordingly, an object of the present invention is to provide a packaging box that can improve transportation efficiency and reduce the labor of packaging work.

  In order to solve the above-mentioned problems, the present invention is directed to an opposing side wall whose upper side is a hypotenuse, an end wall connected to the side wall to form a peripheral wall, a rectangular bottom wall, and an inclination along the hypotenuse of the side wall. And a cover plate that forms the roof surface. The cover plate opens and closes the roof surface as it swings.

  In addition, the roof surface formed by the cover plate is inclined in both directions so that the central portion is high.

  Alternatively, the roof surface formed by the lid plate is inclined to one side so that one end is high and the other end is low.

  Further, the lid plate is connected to the upper side of the end wall, and the lid plate and the oblique side of the side wall are connected via a folding piece, a lid folding line is formed at the boundary between the lid plate and the folding piece, and the side wall and the folding piece. A side fold line is inserted at each boundary, a middle fold line is inserted from the corner on the base side into the folded piece, and an angle formed by the middle fold line and the lid fold line is set smaller than an angle formed by the middle fold line and the side fold line.

  In the pent roof type packaging box according to the present invention, when the lid plate is opened, products such as pouches are stored, and when the lid plate is closed, the upper part of the product is collapsed and gathers in the tall part of the packaging box. Since it can be packaged in a state where is suppressed, packaging with excellent space efficiency can be easily performed.

  And by using the inclination of the cover plate, using a small outer box without reducing the number of items stored by storing in the outer box in a square shape when viewed from the side wall direction by combining multiple pieces Can be packed on pallets, etc., and transported efficiently.

  In addition, the lid plate and the hypotenuse of the side wall are connected via a fold piece, a fold line is put in the fold piece, and the angle formed by the fold line and the cover fold line is smaller than the angle formed by the fold line and the side fold line. Since the force in the closing direction acts on the cover plate, it can be easily and reliably sealed.
