Referring to FIG. 1, a packaging box having an inner rear wall structure includes a receiving body 10 having contents stored therein and having an open top surface; A double circumferential wall 12 forming a circumferential wall of the receiving body 10; A lid 20 which is connected to one edge of the receiving body 10 to seal the opening surface; And a connecting wall (13) disposed at the one edge to form a side wall of the receiving body (10) and formed in the same structure as the double circumferential wall (12), the double circumferential wall (12) And an empty space is formed between the two plates forming the circumferential wall 12.

The packaging box according to the present invention can be used for packaging, storage and transportation of various products, including, but not limited to, packaging and storage of dry food such as nuts or aquatic products. For example, the packaging box according to the present invention can be applied to a variety of products such as one, a mainstream or a fruit, and the present invention is not limited by the kind of product accommodated inside the packaging box. The packaging box can be made of paper having an arbitrary thickness and can be made in such a manner that a predetermined portion of the overall shape according to one developed view is folded. However, depending on the structure, features made from a plurality of developed views can be joined together, the surface can be coated, the film can be attached to the surface, and different parts can be bonded. A finishing rim of a nonwoven fabric or a synthetic resin material may be formed along the protruding peripheral portion of the packaging box, and the handle of the synthetic resin or nonwoven fabric material may be independently made and attached. With the exception of these parts, the packaging box can be made entirely of paper, printed and cut in a planar development view, and made into a box shape in a folding manner.

The receiving body 10 may be box-shaped having a receiving space therein, and may include a bottom surface 11 and a double circumferential wall 12 surrounding the bottom surface. When the bottom surface is a square, the double circumferential wall 12 may be composed of three walls surrounding the bottom surface. A connecting wall 13 having the same or similar structure as the double circumferential wall 12 may be formed between the receiving body 10 and the lid 20. [ The receiving body 10 may be formed by the double circumferential wall 12 and the connecting wall 13. The perimeter wall 12 can be made in a folding manner, for example a paper foldable material, such as paper, and can consist of two opposing plates and a thickness surface connecting the upper portions of the opposing plates. And an empty space can be formed by the separation distance of the facing plate, and the empty space can have a shock absorbing function and a heat insulating function. Also, the formation of the empty space prevents damage due to the contact of the side wall generated during the process of receiving the contents.

When the contents are received in the inside of the packaging box, the contents are arranged in a receiving case such as a storage case which can be accommodated in the inside of the packaging box, and the receiving case can be received in the receiving body. In the packaging box according to the present invention, the contents are directly disposed on the receiving body 10 without a receiving case. The double circumferential wall 12 and the connecting wall 13 may have the function of preventing the contents from being damaged due to contact during the arrangement, transportation and storage of the contents, and simultaneously absorbing internal or external impacts.

The lid 20 may be connected to one edge of the receiving body 10 and may be connected to one side of the bottom surface 11 to form one developed view. The connection wall 13 may be disposed at the connection portion between the bottom surface 11 and the lid 20 and the connection wall 13 may be made of the same or similar structure as the double circumferential wall 12. [ However, the double circumferential wall 12 may be formed in a shape connected to one side of the bottom surface 11. On the contrary, the connecting wall 13 is disposed on the interface between the bottom surface 11 and the lid 20 in such a manner that the connecting wall 13 is formed independently and joined to the end portions of the two double circumferential walls 12 facing each other. Accordingly, the outer plate of the connecting wall 13 may have a structure in which two plates are overlapped.

The lid 20 may be composed of a sealing surface 21 for sealing the opening surface of the receiving body 10 and a fixing surface 22 for fixing one end of the sealing surface 21. The lid 20 may be formed to extend from one side of the bottom surface 11 and the sealing surface 21 and the fixing surface 22 may be separated on the basis of the folded portion.

Referring to FIG. 2, the bottom surface 11 and the sealing surface 21 may be connected to each other by a folding boundary line, and both ends of the connecting portions may be connected by a folding blade 131. The folding wing 131 may have a fan shape and a folding line may be formed in a height direction in a central portion thereof. The folding wings 131 may be folded by a folding line to form a fan-shaped boundary extending inwardly from both ends of the connecting portion. The connecting wall 13 has a connecting projection 132a, a wall face 132b, a thickness forming face UD and two wall faces 132c which are in turn connected to each other so that fixing projections 133 are formed on both sides of the two wall faces 132c .

Both ends of the connecting surface 132a are inserted between the end portion of the double circumferential wall 12 facing each other and the bottom surface so that the lower portion of the connecting wall 13 is fixed. The wall surface 132b forms an outer plate of the connecting wall 13 and the two wall surfaces 132c can form an inner plate of the connecting wall 13. [ The thickness forming surface UD is a thickness surface connecting the one wall surface 132b spaced apart from the other and the upper portion of the two wall surfaces 132c and is in parallel with the bottom surface 11 in the assembled state. The fixing surface 132d formed on the outer side of the two wall surfaces 132c can be inserted into the lower portions of the one wall surface 132b and the two wall surfaces 132c in the assembled state. The folding wings 131 in the folded state are inserted into the spacing spaces formed at both ends of the first wall face 132b and the second wall face 132c to have the function of coupling the connecting wall 13 to the double circumferential wall 12 .

The fixing projections 133 may be formed at both ends of the two wall surfaces 132c so that the connecting wall 13 is firmly engaged with the double circumferential wall 12. The fixing projections 133 may be formed on the inner plate of the double circumferential wall 12, And an engaging groove 121 into which the engaging portion 133 is inserted. The engaging groove 121 can be formed in a slit shape along the height direction of the double circumferential wall 12 and the fixing protrusion 133 can be formed into a suitable shape to be inserted into the engaging groove 121. [ The connecting wall 13 can be stably coupled to the double circumferential wall 12 by the connecting face 132a, the folding wing 131 and the fixing protrusion 133. [ In addition, the connecting wall 13 is independently formed into a rear wall structure having a thickness similar to that of the double circumferential wall 12, so that the contents can be directly received in the receiving body and sealed and packaged by the lid to be transported or stored.
