Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a corrugated packaging box material that can easily produce a corrugated packaging box in which a buffer frame is integrated into the packaging box body.

(Prior Art) Various structures are known for corrugated packaging boxes depending on the type of items to be packaged. Despite the fact that the most common cardboard packaging boxes for heavy goods, which are equipped with a series of flaps, require the use of a buffer frame during packaging to prevent the packaged items from moving or being damaged within the box. I can't find anything with a buffer frame. For this reason, when packing, it is necessary to set a separately prepared buffer frame inside the box, fit the buffer frame above the package after storing the packaged items, and then seal the box after closing it with a flap. The drawback was that it required a lot of work.

(Problems to be solved by the invention) The problems to be solved by the invention are that not only can a cardboard packaging box without the above-mentioned drawbacks be easily provided, but also that almost no waste can be produced from a single cardboard blank. To provide a convenient corrugated cardboard packaging box material which can be manufactured without causing any damage, thereby reducing costs, and which can be folded and stored without taking up bulk when not in use.

(Means for Solving the Problems) The present invention consists of two side plates of every other strip of strip material, in which four rectangular side plates are connected to each other via folding lines for inward folding. An outer flap for forming the top cover is connected to the upper edge via a folding line for inward folding, and an outer flap for forming the bottom cover is connected to the lower edge of the two side plates via a folding line for inward folding. Further, a corner plate part for forming the upper support frame is successively provided on the upper edge of the other two side plate parts via a folding line for inward folding, and each corner plate part is connected to the folding line. The folding lines for inward folding and the folding lines for outward folding which are parallel to each other form sections into three belt-shaped frame parts and a belt-shaped fixing plate part, and furthermore, a section is formed under the other two side plate parts. Corner plate parts for forming the lower support frame are connected to the edges via folding lines for inward folding, and each corner plate part has a folding line for inward folding parallel to the folding lines for forming the bottom support frame. A section is formed in the square frame part, and the square frame part is provided with a vertical cut reaching the folding line and a cut connecting the cuts on the folding line at the lower part of both sides of the square frame part. A folding line for inward folding that connects the lower ends of the cut, a folding line for outward folding that connects the upper part of the cut, and a folding line for inward folding that reaches the side edge of the square frame material from the middle part of each cut. Using a blank plate for assembling a corrugated packaging box, in which a folding line is provided, a band-shaped fixing plate is formed between the cut and the folding line, and a frame top plate is formed below the folding line, Of the upper corner plate parts of the other two side plate parts mentioned above, the part above the folding line for inward folding is folded 180 degrees inward from the folding line, and the band-shaped fixing plate part on the other side is folded inwards from the folding line. In addition to adhesively fixing it to the inner surfaces of the two side panels,
Of the corner plate parts on the lower side, the part below the folding line for inward folding is folded 180 degrees inward from the folding line, and the band-shaped fixing plate part formed on the square frame part is folded into the band-like shape. Glue and fix to the inner surface of the bottom of the frame, and
The strip material is characterized in that it is folded 180 degrees inward from a central folding line for inward folding, and its both ends are connected.

(Example) Next, the present invention will be described in detail using a cardboard packaging box for packing an electric ventilation fan as an example.

It is packed so that it will not move or be damaged inside the box, and the packing process only requires folding the flattened packaging box along the folding line, and while incorporating a separately prepared buffer frame, Packing is greatly simplified compared to conventional cardboard packaging boxes.

(Effects of the invention) As is clear from the above description, the present invention can be kept in a flat folded state at all times, so it can be stored in stacks without taking up much space. By simply folding the flap using an operation similar to bending the flap, it is possible to form a buffer frame for supporting the packaged item integrally with the packaging box body, which has a recess at the opposite position of the inner bottom, and also to form a buffer frame for supporting the packaged item. When the lid is closed, it can be protected by the buffer frame for the upper presser that is integrated with the packaging box body, and can be packed automatically with good packaging efficiency. Since it can be manufactured without wasting cutting, it has the advantage of being able to be provided at a low cost, and has extremely great practical value.
