Buffer box structure

The present invention relates to a cushioning structure, and more particularly to a cushion box structure.

With the rise of online commerce, the demand for distribution and distribution of goods has also increased significantly. In order to prevent the surface from being scratched during the delivery, or to prevent the product from moving, the outer surface of the box is usually placed on a cushion or packaged in a buffer bag.

However, for large-volume or high-weight objects, cushions or buffer bags may still be broken due to friction and wear due to long-term transportation. Therefore, a buffer box is usually combined with a plurality of air column sheets, and an object is placed therein, and the whole is placed in the outer box.

However, the current problem is that when a plurality of gas column sheets are joined, it is easy to produce a situation in which the outer surface is protruded, so that the inner surface of the air column and the outer box cannot be attached, so that the space utilization rate is poor, and the buffer box is also in the outer box. It is still possible to move and wear and reduce the cushioning effect. In addition, in order to reduce these protrusions, cutting may be required, which requires an additional manual cutting process, which undoubtedly increases production time, cost, and waste of materials. Therefore, it is necessary to design a buffer box structure that can solve the above problems.

In view of this, the present invention provides a buffer box structure. The buffer box structure comprises two gas column pieces, and each of the gas column pieces comprises two first gas column regions, one second gas column region and two non-intake regions.

The non-intake zone is located on both sides of the second air column region and adjacent to the first air column region, wherein the boundary between the second air column region and the non-intake region forms a third turning line. The two gas column sheets are respectively turned along the first turning line and the second turning line, and are arranged oppositely in an inverted manner, and the edges of the first gas column region of the two gas column and the edge of the second gas column region are butted against each other. And the non-intake area is folded after being folded along the third turning line after docking, and a buffer box structure is formed.

In one embodiment, each gas column further comprises two longitudinal boundaries, two lateral boundaries, a plurality of first longitudinal heat seal lines, a plurality of second transverse heat seal lines, a second transverse heat seal line, and a third Horizontal heat seal line.
