Referring to fig. 1, an embodiment of the present application provides a buffer packaging structure with different shrinkage rates. Specifically, as shown in fig. 6, after the cushioning packaging structure of this embodiment is opened, the inner space of the cushioning packaging structure can be designed to accommodate a flat product (not shown), such as a notebook computer or a tablet computer. That is to say, the cushioning packaging structure of this embodiment can be regarded as the protection bag of a notebook computer for the notebook computer is in the transportation process, and six planes of notebook computer have suitable protection.

First, the cushion packaging structure of the present embodiment has a wall-shaped cushion body 20W, and three wall surfaces bent into a U-shape are a first cushion wall 20A, a second cushion wall 20C, and a transition cushion wall 20B. In addition, in the present embodiment, two first air columns 10 are used and then bent into a U-shape to protect the other three surfaces, i.e. the front opening and two side openings of the U-shaped wall-shaped buffer body 20W are enclosed. Therefore, the protection of the flat-plate-shaped product in the transportation process can be provided.

The first air column 10 has a transverse section 11 extending along a first direction, i.e. the X-axis direction in fig. 1, and two lateral sections 12 bent from two ends of the transverse section 11 and extending along a second direction, i.e. the Y-axis direction in fig. 1. The wall-shaped buffer body 20W is formed by connecting a plurality of second air columns 20 in parallel, and the second air columns 20 extend in a second direction between the first buffer wall 20A and the second buffer wall 20C, i.e. the Y-axis direction in fig. 1, or may be referred to as the longitudinal direction of the second air columns 20. The second air column 20 extends along a third direction in transition with the second buffer wall 20C, i.e. the Z-axis direction in fig. 1. The bend of the second air column 20 may be a spot or short line shaped weld, such as the weld 22 of fig. 1, and the two sides of the bend may still be in air communication. The bend of the first gas column 10 is also of similar construction.

Referring to fig. 2 to fig. 4, the first buffer wall 20A of the wall-shaped buffer body 20W is taken as an example for explanation. FIG. 2 is a cross-sectional view showing the first baffle wall 20A and the first gas column 10 in a flattened state when not inflated. Fig. 3 shows a front view of the first cushioning wall 20A when it is not inflated, and is also flat, and the wall-like cushioning body 20W when it is not inflated has a small volume for storage and re-inflation when it is desired to be packaged, as in the state of fig. 4. As shown in FIG. 3, each second gas column 20 has an original width L in the uninflated state. As shown in fig. 4, after the first buffer wall 20A is inflated, each second air column 20 has a cylindrical shape, and the diameter of the second air column 20 is R. In the present embodiment, the diameter R of each second gas column 20 is equal to the diameter of the first gas column 10, but the present application is not limited thereto.

Referring to fig. 3 and 4, the first buffer wall 20A has a width in the X-axis direction that is reduced after being inflated. Specifically, the original width L of the second air column 20 is the diameter R × 3.14 × 0.5. After calculation, the original width L is 1.57 times the diameter R. In other words, the width of the wall-shaped cushion body 20W in the direction perpendicular to the second direction (Y-axis direction) when it is not inflated, i.e., the total width of the plurality of second air pillars when they are not inflated, is 1.57 times the length of the lateral section 11 of the first air pillar 10, i.e., the first preset multiple. Assuming that the width of the welding bead (S11, see fig. 2) between the second air pillars 20 is not calculated first, the contraction rate of the first buffer wall 20A after inflation along the first direction (X-axis direction) is 1/1.57.

The first gas column 10 is not contracted when it is not inflated and when it is inflated, and is not contracted in the first direction (X-axis direction) after it is inflated, and the contraction rate is 0. Therefore, the cushion packaging structure of the present embodiment has the front opening in the uninflated state and the inflated state, and the first air column 10 and the plurality of second air columns 20 along the first direction (X-axis direction) have different shrinkage rates. In the case of forming two sheets of cushion packaging material into a linear weld line by a general heat welding method, the first cushion wall 20A having a large shrinkage rate pulls the first air pillar 10 having a small shrinkage rate after inflation. This is a key issue to be solved by the structure of the cushion packaging with different shrinkage rates of this embodiment. Details of the present embodiment to address the different shrinkage rates are described in detail below.

The present embodiment has a cushioning packaging structure with different shrinkage rates, and can be applied to only one cushioning wall. The first buffer wall 20A includes a wall-shaped buffer body 20W formed by connecting the first air column 10 and the plurality of second air columns 20. The lateral section 12 of the first air column 10 may be omitted, and the first air column 10 (the transverse section 11) extends in a first direction (the X-axis direction, or a lengthwise direction considered as the transverse section 11). The first air column 10 has a side flap 13, the side flap 13 being connected around the first air column 10 and extending along the first air column 10.

The wall-shaped cushion body 20W has a plurality of second air columns 20 and end flaps 25, and the plurality of second air columns 20 are connected in parallel to each other in the second direction (Y-axis direction). In the present embodiment, the second direction is perpendicular to the first direction, however, in general, the second direction of the present application may be different from the first direction. An end flap 25 is attached to the closed end of the second plurality of air columns 20.

As shown in fig. 2, the inside of the end flap 25 of the first buffer wall 20A is formed with two parallel welding strips S21, S22 to form an inflation passage H through which AIR (AIR) can be inflated to the plurality of second AIR columns 20 through the plurality of check valves 27. The first cushion wall 20A is also connected to the first air column 10 on each side by an outer flap 26.

One of the structural features of the present embodiment is that, as shown in fig. 2, the total width W20 of the first baffle wall 20A when uninflated along the first direction (X-axis direction) is equal to a first predetermined multiple of the length W10 of the first air pillar 10 (transverse segment 11) after inflation (or in an uninflated state). As shown in fig. 1 and 2, the first baffle wall 20A is in an uninflated state in which the end flaps 25 of the wall-like baffle body 20W are arranged in a wavy shape and form a plurality of weld points D with the side flaps 13 of the first air pillar 10. Thereby, after the first buffer wall 20A of the wall-shaped buffer body 20W of the present embodiment is inflated and contracted, the total width of the plurality of second air columns 20 along the direction perpendicular to the second direction is equal to the length W10 of the first air column 10 (the transverse section 11). Described by another angle, between two adjacent welding points D, the length W21 of the end flap 25 of the corresponding segment is equal to a first preset multiple of the length W11 of the side flap 13 of the corresponding segment of the first air pillar 10.

In addition, the welding point D of the present embodiment is located between two adjacent second air columns 20 with respect to the first buffer wall 20A of the wall-shaped buffer body 20W. And it is preferable that the welding point D is located at the end of the welding strips S21, S22 of two adjacent second air columns 20 close to the inflation channel H, which is advantageous in that the inflated end of the second air column 20 abuts the first air column 10, resulting in better cushioning protection effect. The weld points D are prevented from falling into the inflation passage H, or outside thereof, so as not to have an uninflated portion between the first and

second air pillars

10 and 20. On the other hand, the welding points D are also prevented from blocking the inflation channel H. Furthermore, the folded end flap 25 after inflation can be covered under the side flap 13 of the first air column 10, and the exposed part is the straight side flap 13, so that the appearance is more attractive.

When the cushioning packaging structure of the present embodiment is applied to package and protect a notebook computer, or called a cushioning packaging structure of a flat-plate-shaped product, two straight U-bent first air pillars 10 are disposed between the first cushioning wall 20A and the second cushioning wall 20C, and a zipper 30 is disposed on the two U-bent first air pillars 10. The above-described connection features of the end flap 25 of the first damper wall 20A with the side flap 13 of the first air column 10 are, similarly, also applied to the connection between the end flap of the second damper wall 20C and the side flap of the first air column 10 below. This section will not be repeated.

Specifically, the present embodiment is applied to a cushion packaging structure of a flat plate product, which includes a wall-shaped cushion body 20W, two first air columns 10 and a zipper 30. The wall-shaped cushion body 20W has a plurality of second air columns 20 connected in parallel, and two end flaps 25, and the two end flaps 25 are connected to the ends of the plurality of second air columns 20, respectively. The wall-shaped buffer body 20W is bent to form a first buffer wall 20A, a second buffer wall 20C, and a transition buffer wall 20B, and the transition buffer wall 20B is connected between the first buffer wall 20A and the second buffer wall 20C in a gas-communicable manner. One of the first air columns 10 is connected to three sides of the first buffer wall 20A in a bending manner, the other first air column 10 is connected to three sides of the second buffer wall 20C in a bending manner, and each first air column 10 is provided with an inner side flap 13 and an outer side flap 13. The end flap 25 of the wall-shaped cushion body 20W is provided in a wavy shape and forms a plurality of welding points D with the outer side flap 13.

The zipper 30 is connected to the two first air pillars 10 at both sides thereof, respectively. Both sides of the zipper 30 may be attached to the side flaps 13 inside the first air pillar 10 by means of sewing threads.

Referring to fig. 5, the cushion packaging structure of the present embodiment further includes a portable belt connected to the wall-shaped cushion body 20W. The carrying strap may be a strap or a carrying strap. The advantage is that the cushion packaging structure can be continuously used as a laptop bag or a hand bag for carrying a laptop or carrying a laptop. Unlike previous cushion bags, which generally do not provide other uses, they are typically discarded after the product is shipped. The cushioning packaging structure of this embodiment can continue to be used as a laptop bag for the second purpose.

Specifically, as shown in fig. 5 and 6, the carrying strap may include a pair of ear straps 40 and a back strap 41, wherein both ends of the back strap 41 are detachably connected to the pair of ear straps 40, and the pair of ear straps 40 are respectively connected to both sides of the wall-shaped buffer body 20W. Specifically, the ear band 40 is welded between the first air column 10 and the outermost second air column 20, and is close to the transverse section 11, i.e. the bending part of the first air column 10.

Please refer to fig. 6, which illustrates a schematic view of the buffering package structure of the present application as a mobile desktop of a notebook computer in an opened state. The design of the ear belt 40 and the back belt 41 may be extended to another third use. The cushion packaging structure of the present embodiment may further include two position-limiting belts 50, wherein the two position-limiting belts 50 are respectively connected to the inner sides of the first cushion wall 20A and the second cushion wall 20C, and are adjacent to the first air column 10. The two limiting belts 50 can limit the opening angle of the first buffer wall 20A and the second buffer wall 20C, and can also protect products placed inside from sliding outwards. Therefore, the user can operate the notebook computer by carrying the straps 41 while using the cushioning packaging structure as a mobile desktop of the notebook computer.
