Description

Packing Box {Packaging box}

The present invention relates to a packaging box having improved impact resistance for transporting and packaging an article susceptible to impact.

In general, the packaging box is made in the form of a hexahedron with an empty interior, and after bending such a development site while cutting corrugated paper into a hexahedron shape, it is possible to bond or fix the staples to each other. It is firmly fixed and manufactured to have an opening on top.

In addition, in order to prevent the product from being damaged from impacts or loads in various directions acting on the packaging box, the inside which is accommodated in the packaging box by putting various types and types of cushioning materials between the product and the packaging box. It prevents the product from being damaged from external force or impact.

However, the packaging box of the general form is developed by cutting a single layer of corrugated cardboard, bending and adhesive fixing it to have a hexahedron shape empty inside. Since the packaging box protects the internal products only by the physical rigidity of the cardboard itself, the deformation of the box easily occurs when a large number of boxes are stacked or excessive loads or momentary concentrated or impact loads are generated. have.

In addition, when an external force is applied from the side of the box in a vertically stacked state, the shock absorbing material may pour out or the internal product may be damaged or broken while the box is broken due to external force or impact.

In addition, even if the reinforcing member is applied to the packaging box itself, there is a limit to increase the rigidity of the box, there is a disadvantage that the manufacturing step is complicated.

Therefore, in the case of expensive items or items susceptible to impact, it is common to apply a shock-absorbing package and a durable package to the product itself and put it in a packing box irrespective of the packing box. It is intended to solve the above problems by filling a more effective cushioning material.

However, the above-mentioned solution also takes too much cushioning material, and the cushioning and durable packaging of the product itself is concentrated, which acts as a factor of unnecessary cost increase, and excessively compared to the actual packaged goods for sufficient buffering action. After applying a large packaging box there is a problem in that the burden of increasing the logistics costs due to the increase in the volume of the packaging box by filling a large amount of cushioning material therebetween.
