[Prior art]

 2. Description of the Related Art Conventionally, as this type of packaging box, there is known a packaging box that has a so-called one-touch assembling bottom portion and that can be easily assembled into a box shape or folded into a flat state. That is, a packaging box of this type includes, for example, a pair of first side plates standing upright opposite to each other and a pair of second side plates standing upright opposite to each other and connected to the respective side edges of the first side plates. It has a body part formed in a square tube shape, and has a first bottom flap continuous with a lower edge of each of the first side plates and a second bottom flap continuous with a lower edge of each of the second side plates. ing. A bending adhesive piece is formed on one side of each of the first bottom flaps via a fold line that is inclined at an angle of 45 ° from the lower edge of the first side plate. The bent adhesive piece of the one-bottom flap is fixed to one of the second bottom flaps, and the bent adhesive piece of the other first-bottom flap is fixed to the other second bottom flap. When the body is folded along one of the four corners of the body, the bottom flaps stand up inside the body and are stored, so that the entire packaging box is flat.

Further, when a fragile object to be packaged is housed in the packaging box configured as described above, generally, a block-shaped polystyrene foam resin is provided between the object to be packaged and the inner peripheral surface of the body. A cushioning member made of aluminum is interposed. By interposing the cushioning member in this manner, the packaged article is securely supported in the packaging box, and the cushioning effect of the foamed styrene resin protects the packaged article from an external impact. ing.

By the way, in the packaging box having the above structure, when the packaged object is stored in the packaging box, the packaging box and the cushioning member are separately prepared. In this case, since the packaging box can be folded as described above, it can be efficiently stored and handled by being folded flat before use without taking place. However, since the cushioning member cannot be folded because it is block-shaped, not only is the storage location limited, but it is also difficult to store it together with the packaging box.

Further, a cushioning member formed in the shape of a thick plate by stacking a plurality of corrugated paperboards is interposed between the packaged body and the inner peripheral surface of the body part, and the packaged body is externalized by the cushioning action of the corrugated board. There is also proposed a structure that protects it from a shock from a vehicle, but even in this case, it may be difficult to fold depending on the thickness of the cushioning member. Further, if a cushioning member made of corrugated paperboard of this kind is formed in consideration of folding, there is a disadvantage that a sufficient cushioning action cannot be obtained.

Further, it is most desirable to fold the packaging box flat while the packaging box is provided with a cushioning member. In particular, like the packaging box, each bottom flap is placed inside the body. When the one-touch assembly bottom part is constructed so that it can be stood up and stored, the edge part along the fold line of the bent adhesive piece of each rising first bottom flap interferes with the cushioning member and is surely flat. There is an inconvenience that the state cannot be set.

[0007]

As a result, the packaging box is flatly folded together with the buffer section. At this time, at the bottom of the packaging box, each of the first bottom flaps is housed inside the body while being bent at an acute angle through the fold line, but a space is provided between the cushioning member and the bottom. Therefore, one edge of each first bottom flap raised at an angle of 45 ° along the fold line of each first bottom flap is housed in the void, whereby one end of each first bottom flap is accommodated. The rim can be prevented from interfering with the cushioning member, and folding can be performed with the cushioning member provided in the body portion.

On the other hand, in the state where the articles to be packaged are accommodated in the accommodation space of the inner wall, the vertical interval holding pieces are arranged in parallel with each other between the inner surface of the inner wall and the inner surface of the body portion at a predetermined interval. Therefore, when a shock is applied to the trunk from the outside, this shock force is received by the inner wall and the vertical gap holding piece.

Further, by providing the receiving member, the object to be packaged is located in the storage space, and when the impact is applied from the bottom side, the shock absorbing action of the receiving member absorbs the impact. It is possible.
