Background Technology
[0002] For example, in Taiwan Patent No. M541708, although this method can reduce damage to goods, the packaging process is too complicated, and the protective packaging materials required also take up a lot of space. After packaging, the shape is irregular and difficult to store. In particular, the materials used are not environmentally friendly and cannot be recycled. The function is relatively simple, with only a cushioning function and no other additional functions. Summary of the Invention

[0034] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0035] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or position based on the orientation or position shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0036] Example 1:
[0037] See Figure 1 and Figure 2 Packaging bag 1 includes:
[0038] 11. Outer wall portion;
[0039] An inner wall portion 12 is located on the other side of the outer wall portion 11, and the inner wall portion 12 surrounds to form an accommodating space 13;
[0040] At least one buffer body 2, which is made of recyclable paper and is set in the accommodating space 13 in a pre-formed manner;
[0041] A plurality of honeycomb holes 22 (hexagonal solid form) are formed on the buffer body 2. Each honeycomb hole 22 includes a polygonal perimeter 221 and a high side 222 formed by the perimeter 221 extending vertically, thereby making the honeycomb hole 22 form a 3D solid form. The perimeter 221 has a plurality of grid edge portions 2211, and there is an included angle portion 2212 between each grid edge portion 2211.
[0042] The outer wall portion 11 and the inner wall portion 12 are the outer and inner sides of the packaging bag 1, respectively.
[0043] In this embodiment, the pre-formed shape is shaped by a wet drying method. The buffer body 2 is first stretched and unfolded, and then liquid (such as a humidifier) is sprayed on the surface of the buffer body 2 to make the buffer body 2 semi-wet. Finally, the buffer body 2 is dried (such as a dryer) under continuous stretching. When the buffer body 2 is dried, it is in a shaped state. This state will make the multiple honeycomb holes 22 on the buffer body 2 form an unfolded 3D three-dimensional shape.
[0044] The honeycomb mesh 22 has six grid edges 2211 and six corner portions 2212, with each corner portion 2212 having an angle of 45 degrees to 180 degrees. When the honeycomb mesh 22 is stretched and shaped to provide shock absorption and cushioning, the angle can be less than 180 degrees. When the honeycomb mesh 22 on the edge of the buffer body 2 is pressed and fixed to the packaging bag, the angle is 180 degrees.
[0045] Packaging bag 1 is made of flexible materials such as soft paper or fiber.
[0046] The packaging bag 1 is provided with a cover 14 for sealing the containment space 13.
[0047] In this example, the outer side 21 of the buffer body 2 facing the inner wall 12 is not fixed to the inner wall 12 (meaning there is no glue or binding or other fixing structure), and the total area of the outer side 21 is smaller than the total area of the inner wall 12, so that the buffer body 2 can be placed in the receiving space 13 of the packaging bag 1 (envelope bag).
[0048] refer to Figures 3 to 5 ,like Figure 3 The cushioning element 2, positioned before the receiving space 13 of the packaging bag 1, is already pre-formed. During manufacturing, it is simply stacked with the unsealed packaging bag 1 on the production line and then sealed after processing, allowing the cushioning element 2 to be directly located within the receiving space 13. No further stretching, unfolding, or additional adhesive methods are required to fix it to the packaging bag 1. Because the cushioning element 2 has a 3D three-dimensional appearance, it provides effective protection, such as… Figure 4 After placing item 3 into the receiving space 13 and closing the cover 14 (adhesive tape can be added to the cover 14 to enhance the sealing effect), item 3 is protected by the shock-absorbing effect of the buffer 2. When item 3 is an electronic device or a fragile item (such as a glass bottle), even greater protection is needed. Figure 5 If packaging bag 1 falls and hits the ground, item 3 can be cushioned by buffer 2, preventing damage to item 3. (See reference) Figure 1 , Figure 2 , Figure 5, when the packaging bag 1 hits the ground instantaneously, the impact force will be transmitted from the outer wall portion 11 of the packaging bag 1 to the inner wall portion 12, and then from the inner wall portion 12 to the buffer body 2. The impact force is dispersed in the first stage through the grid edge portion 2211 of the buffer body 2, and the remaining impact force will be absorbed and offset by the high edge 222. The thickness extension direction of the high edge 222 faces the outside of the packaging bag 1. Therefore, the impact force will be supported by the buffer distance formed by the thickness of the high edge 222 and the included angle portion 2212 supporting the high edge 222, so that when the high edge 222 receives the impact force, it is supported by the included angle portion 2212 instantaneously and the buffer distance serves as an elastic space to effectively and completely absorb the impact strength and prevent the article 3 from being bruised.
[0049] During the process of combining the pre-shaped buffer body 2 with the packaging bag 1 in advance, there is no need to stretch the buffer body 2. Moreover, in this example, the outer surface 21 of the buffer body 2 can present several 3D three-dimensional expanded patterns of honeycomb holes 22 without being fixed to the inner wall portion 12 and in the accommodation space 13. Therefore, the packaging bag 1 has the advantages of quick installation and fewer processing procedures because it does not need to be fixedly adhered, and the buffer space separated by the high edge 222 makes the packaging bag 1 have a shock-resistant buffer effect. Also, the buffer body 2 is made of paper, so it has the advantages of environmental protection, renewable and recyclable.
[0050] Embodiment Two:
[0051] Refer to Figure 6 , in this example, the pre-shaping method uses a roller device to roll the peripheral edge 221 of the surface of the buffer body 2, so that at least one side fold 2213 is generated on both the upper and lower sides of the peripheral edge 221, and at least one middle fold 2221 is generated on the high edge 222. In this example, six side folds 2213 are taken as an example for each side, and several middle folds 2221 are taken as an example. When the buffer body 2 passes through the folding edge stress relationship between the side fold 2213 and the middle fold 2221, it will not rebound, and the buffer body 2 can present an expanded state in a shaped form.
[0052] Embodiment Three:
[0053] Refer to Figures 7 to 10, in this example, an inner layer body 4 made of a soft, flexible, smooth, and waterproof (with a waterproof coating on the surface) material is provided on the side of the buffer body 2 facing away from the inner wall portion 12. The buffer body 2 has an inner side surface 24 facing the inner layer body 4. The inner side surface 24 is not fixed to the inner layer body 4, and there is no fixing element between the inner side surface 24 and the inner layer body 4 to connect and fix the two. In the manufacturing process, only the edge sides of the buffer body 2, the inner wall portion 12, and the inner layer body 4 need to be edge-sealed to complete the manufacturing process, which is obviously very simple, fast, and convenient as a whole, thus enhancing the industrial competitiveness. Of course, when the inner side surface 24 is to be fixed to the inner wall portion 12 and the inner layer body 4 in a three-way manner, the buffer body 2 can be fixed by using the side edges of the inner side surface 24, the inner layer body 4 of the packaging bag, and the inner wall portion 12, so that the buffer body 2 is not likely to move out of position and cause the loss of the shock-resistant buffering effect. In other words, a sandwich layer is formed between the inner wall portion 12 and the inner layer body 4, and the buffer body 2 can be arranged in the sandwich layer to form a three-layer structure composed of the inner layer body 4, the buffer body 2, and the inner wall portion 12. This three-layer structure not only achieves the aforementioned advantages, but also prevents the item 3 from scratching the buffer body 2 through the barrier of the inner layer body 4, resulting in a reduction in the buffering effect, and even prevents the cold air of the item 3 from making the buffer body 2 moist and losing the buffering effect. When the item 3 is fresh food, the item 3 can be placed in the accommodating space 13. At this time, most of the cold air emitted by the item 3 has been blocked by the inner layer body 4. At the same time, together with the isolation space 23 surrounded by the inner wall portion 12, the inner layer body 4, and the high edge 222, the remaining cold air passing through the inner layer body 4 is surrounded in the isolation space 23 to form a second isolation wall, effectively slowing down the temperature change rate in the accommodating space 13 and achieving the advantage of cold preservation. Such as a cold storage bag, of course, it can also be used for heat preservation, heat insulation, or accommodating and storing vaccines.
[0054] Example 4:
[0055] Refer to Figure 11 , 12 , in this example, two sandwich layers and two buffer bodies 2 are taken as examples, and the inner wall portion 12 and the inner layer body 4 are also edge-sealed at the adjacent sides. The two buffer bodies 2 are respectively arranged in each non-communication sandwich layer, and the inner wall portion 12 and the inner layer body 4 are edge-sealed on all four sides to achieve another different setting pattern. In addition, in this example, the outer side surface 21 of the buffer body 2 and the inner wall portion 12 are taken as being fixed. That is, the buffer body 2 can be fixed by using the side edges of the outer side surface 21, the inner layer body 4 of the packaging bag 1, and the inner wall portion 12 to form a fixing area 5, so that the buffer body 2 is not likely to move out of position and cause the loss of the shock-resistant buffering effect.
[0056] Example 5:
[0057] Refer to Figure 13 , in this example, at least one handle member 15 is provided on the packaging bag 1, which is convenient for carrying through the handle member 15 and further prevents the packaging bag 1 from falling, effectively protecting the item. Even if the packaging bag 1 falls, it can be protected by the buffer body 2.
[0058] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
