The present invention relates to a packaging box, and more particularly, to a packaging box having a shock absorbing structure and a manufacturing method thereof so as to provide a shock absorbing structure to reduce the use of additionally added buffer material when packaging the product. .

Many types of goods produced industrially or agriculturally and traded in the same way as sales are designed to increase the value of the goods and to attract consumer attention from the visual point of view, as well as to protect the goods contained therein. It is generally packaged using a suitable form of packaging material such as a packaging box to improve the convenience of transportation.

1 is a perspective view showing a partially assembled state of the packaging box of the basic form according to the prior art, Figure 2 is a development view showing the original paper for manufacturing the packaging box of FIG.

The packaging box of the basic form according to the prior art, as shown in Figures 1 and 2, when assembled, the front 101, rear 103, left side 107, right side 109, bottom surface 111 It consists of a rectangular parallelepiped shape including a cover surface, and has a space for accommodating an article therein. Such packing boxes can be manufactured in a suitable size according to the size and packing unit of the package to be packaged, such as packaging for home appliances expected to be considerable size, fruit such as apples and pears, ramen or snacks It is used in a variety of ways, such as to wrap the back, or to use for packaging small parcels when using the postal service.

Such a packaging box may be manufactured from a single sheet of cardboard formed by properly cutting a kind of cardboard such as cardboard, and as shown in FIG. The first side surface 121 includes a first side surface 121, a second side surface 123, a third side surface 127, and a fourth side surface 129, which form a right side surface. Two pairs of main wing surfaces 131 provided at the upper and lower ends of the 121 and the third side surfaces 127, respectively, and the second side surfaces 123 and the fourth side surfaces facing each other during assembly and having relatively small left and right widths. And two pairs of auxiliary wing surfaces 133 provided at upper and lower ends of 129, respectively, for joining the first side surface 121 and the fourth side surface 129 with bonding means such as adhesive or staple. One side surface 121 includes a bonding surface 125 extending from one side end.

The process of assembling and packing the packaging box using such original cardboard is as follows. First, the first side surface 121 to the fourth side surface 129 and the joining surface 125 are perpendicular to the adjacent surface in the state where the interface between each surface and the surface is easily processed by compression or the like. The bonding surface 125 and the fourth side surface 129 that are bent and overlapped in this state are bonded by applying an adhesive to the overlapping portion or bonded by using a plurality of staples 130, and the front surface 101 and the rear surface 103 are bonded to each other. The left side 107 and the right side 109 are formed. Subsequently, the pair of auxiliary wing surfaces 133 extending from the lower ends of the second side surface 123 and the fourth side surface 129 are bent at right angles to each other, and then the first side surface 121 and the third side surface ( A pair of main wing surfaces 131 which are adjacent to each other with a slight gap therebetween are bent at a pair of main wing surfaces 131 extending from the lower end of 127 at right angles to each other. Finishing with a tape 135 having or by using a plurality of staples to form a bottom surface 111. In this state, the article to be packaged is introduced, and the cover surface is formed by the same process as that of forming the bottom surface 111 after the article is added, thereby completing the packaging. That is, such a packaging box is used for packaging work in a partially assembled state in which only the bonding surface 125 extending from the first side 121 and the fourth side 129 is joined, thus assembling the packaging box and Packaging work takes place simultaneously.

As such, the packaging box 100 of the basic form has the advantage of being very easy to manufacture and also easy to wrap, but if the weight is to be considered, such as when the weight of the packaged goods is limited because of the limited allowable weight is used as it is. It is difficult to be used, and the appearance is difficult to be neatly arranged, so it is somewhat unsuitable for being used for small and medium expensive items or gift packaging.

Such a packing box 150 is manufactured in the form of overlapping at least two sides in the form of a wall by using a plate having a complex development of a paper, thus improving the article protection ability compared to the thickness of the plate However, it has a shock absorbing capacity that is insufficient for packaging goods in the form of glass bottles such as liquor, wine, coffee, and the like, or for packaging dishes such as fragile glass cups or plates.

In order to solve such a problem, the use of high-strength thick paper with high breaking strength cannot be neatly folded due to the thickness, and thus the decorative condition of the folds must be poor, resulting in decorative considerations. It is a little unsuitable for expensive and gift packaging.

On the other hand, in addition to the packaging auxiliary material required for the packaging of the goods to use the additional cushioning member to secure the required level of article protection capacity, there is a problem that significantly increases the packaging cost with the use of excessive cushioning member is also undesirable. It is true.

In addition, in order to solve the above problems, there has been suggested a packaging box made of wood for the purpose of packaging the goods that luxury should be emphasized, such as high-quality liquor or high-quality wine, this also realizes the appearance luxury Although it may be preferable in terms of the strength of the paper, the shock absorbing ability is rather poor compared to the paper, rather than the paper, if the shock due to inadequate handling, such as dropping the packaging box, even if the damage does not occur 2 There is a problem that the packaged goods may be damaged by the impact of the vehicle, which requires considerable care in handling.
