[0007] The embodiments will be described in detail below with reference to the attached drawings.

[0008] As shown in Figures 1 and 2, the structure of the packaging bag according to this embodiment includes an outer wall portion 11, an inner wall portion 12, a storage space 13, a buffer body 2, and a plurality of honeycomb-shaped holes 22.

[0009] The inner wall portion 12 is located on the other side (opposite side) of the outer wall portion 11, and the inner wall portion 12 surrounds the accommodation space 13.

[0010] At least one buffer 2 is made of recyclable paper and is placed in the containment space 13 in a pre-formed state.

[0011] A plurality of honeycomb-shaped holes 22 (hexagonal three-dimensional shapes) are formed on the cushioning body 2, and each honeycomb-shaped hole 22 includes a polygonal edge portion 221 and a high side portion 222 formed extending vertically from the edge portion 221. Thereby, the honeycomb-shaped holes 22 form a three-dimensional solid shape. Further, the edge portion 221 has a plurality of lattice edge portions 2211, and a corner portion 2212 is provided between each of the lattice edge portions 2211.

[0012] The outer wall portion 11 and the inner wall portion 12 respectively constitute the outer side and the inner side of the packaging bag 1.

[0013] The preforming step in this embodiment is performed by a wet drying method. The cushioning body 2 is first stretched and expanded, then a liquid (for example, from a humidifier) is sprayed onto the surface of the cushioning body 2 to bring it into a semi-moist state, and finally, the cushioning body 2 is dried (for example, in a dryer) while maintaining the stretched state. When the cushioning body 2 dries, the cushioning body 2 assumes a fixed shape. In the state after drying, the plurality of honeycomb-shaped holes 22 formed in the cushioning body 2 form an expanded three-dimensional solid shape.

[0014] The honeycomb-shaped hole 22 has six lattice edge portions 2211 and six corner portions 2212. The angle of each corner portion 2212 is 45 degrees to 180 degrees. The honeycomb-shaped hole 22 is stretched and shaped (stretch-formed), and said angle for the impact buffering effect may be less than 180 degrees. On the other hand, in a state where the honeycomb-shaped holes 22 located at the peripheral edge of the cushioning body 2 are pressed against and fixed to the packaging bag, said angle is 180 degrees.

[0015] The packaging bag 1 is made of a flexible material such as flexible paper material or fiber material.

[0016] The packaging bag 1 is provided with a cover 14 for sealing the accommodation space 13.

[0017] In this embodiment, the outer surface 21 of the buffer 2 facing the inner wall 12 is not fixed to the inner wall 12 (that is, no fixing means such as adhesive or stapler is used at all), and the entire area of the outer surface 21 is smaller than the entire area of the inner wall 12, so the buffer 2 can be easily arranged in the accommodating space 13 of the packaging bag 1 (for example, an envelope bag).

[0018] As shown in Figures 1 to 5, especially Figure 3, the buffer 2 is in a pre-shaped state (preformed shape) before being arranged in the accommodating space 13 of the packaging bag 1. In the manufacturing process, it is only necessary to stack and arrange the buffers 2 on the unsealed packaging bag 1 on the production line, and seal the bag end after processing. The buffer 2 can be directly arranged in the accommodating space 13, and there is no need to stretch or adhere the buffer 2 again, which is simple and convenient. Since the buffer 2 presents a three-dimensional shape, it has excellent protection performance. For example, as shown in Figure 4, by accommodating the article 3 in the accommodating space 13 and closing the cover 14 (note that the cover 14 can be provided with tape or the like to enhance the sealing effect), the article 3 can be protected by the impact resistance and buffering effect of the buffer 2. Higher protection is required when the article 3 is an electronic device or a fragile article (such as a glass bottle). As shown in Figure 5, even when the packaging bag 1 falls and collides with the ground, the article 3 is buffered by the buffer 2, so the article 3 is not easily damaged. For example, as shown in Figures 1, 2 and 5, when the packaging bag 1 collides with the ground, the impact force is transmitted from the outer wall 11 of the packaging bag 1 to the inner wall 12, and then from the inner wall 12 to the buffer 2. The impact force is dispersed in the first stage by the lattice edge 2211 of the buffer 2, and the remaining impact force is absorbed and alleviated by the high side portion 222. Since the thickness direction of the high side portion 222 extends toward the outside of the packaging bag 1, the impact force is combined with the buffering distance provided by the thickness of the high side portion 222 and the support of the high side portion 222 by the corner portion 2212. The moment the high side portion 222 receives the impact force, the corner portion 2212 provides support, and the buffering distance acts as an elastic space, effectively and completely absorbing the impact force to prevent damage to the article 3.

[0019] By pre-shaping the buffer body 2 and combining it with the packaging bag 1, there is no need to stretch the buffer body 2. Furthermore, in this embodiment, the outer surface 21 of the buffer body 2 is not fixed to the inner wall portion 12, and when contained within the storage space 13, multiple honeycomb holes 22 can be presented in a three-dimensional solid shape. As a result, since fixing or adhesive is not required for the packaging bag 1, installation is quick (rapid assembly) and the number of processing steps is reduced (simplification of processing steps). In addition, the buffer space partitioned by the high side portion 222 provides the packaging bag 1 with excellent seismic cushioning function. Moreover, since the buffer body 2 is made of paper material, it has the advantage of being environmentally friendly and recyclable.

[0020] As shown in Figure 6, the pre-forming method in this embodiment is performed by pressure molding the edge 221 of the surface of the buffer body 2 using a roller device. As a result, at least one side fold 2213 is formed on both the upper and lower surfaces of the edge 221, and at least one intermediate fold 2221 is formed on the higher side 222. In this embodiment, a configuration example is provided in which six side folds 2213 and multiple intermediate folds 2221 are provided on each side. Due to the stress relationship of the folds formed by these side folds 2213 and intermediate folds 2221, the buffer body 2 can be unfolded into a certain shape without bouncing back.

[0021] As shown in Figures 7 to 10, in this embodiment, the buffer body 2 is provided with an inner layer 4 made of a soft, flexible, smooth, and waterproof material (with a waterproof coating on the surface) on the side away from the inner wall 12, and the buffer body 2 has an inner surface 24 on the side facing the inner layer 4, and this inner surface 24 is not fixed to the inner layer 4, and there are no fixing members between the inner surface 24 and the inner layer 4 to connect and fix them. Therefore, in the manufacturing process, the manufacturing is completed by simply sealing the periphery of the buffer body 2, the inner wall 12, and the inner layer 4, making the overall process very simple, quick, and convenient, and ultimately contributing to improved industrial competitiveness. Of course, if the inner surface 24 is to be fixed to the inner wall 12 and the inner layer 4 in three directions, the buffer body 2 can be fixed using the inner surface 24, the inner layer 4 of the packaging bag 1, and the side edge of the inner wall 12, thereby preventing displacement of the buffer body 2 and suppressing a decrease in seismic buffering performance. In other words, an intermediate layer is formed between the inner wall portion 12 and the inner layer body 4, and the buffer body 2 is placed in this intermediate layer, thereby forming a three-layer structure consisting of the inner layer body 4, the buffer body 2, and the inner wall portion 12. This three-layer structure not only realizes the above advantages, but also shields the article 3 from the inner layer body 4, preventing damage to the buffer body 2 and suppressing a decrease in the buffering effect. Furthermore, it is possible to prevent the buffer body 2 from becoming wet (wetting) due to the cold air emitted from the article 3, thereby preventing a deterioration in its buffering performance. For example, if the article 3 is a perishable food item, when the article 3 is stored in the storage space 13, most of the cold air emitted from the article 3 is blocked by the inner layer body 4. At the same time, the isolation space 23 surrounded by the inner wall portion 12, the inner layer body 4, and the high side portion 222 surrounds the remaining cold air that has passed through the inner layer body 4, forming a second barrier. As a result, the rate of temperature change within the storage space 13 is suppressed, and the cooling function is achieved. In other words, this structure functions as a cooler bag and can also be used for heat retention, insulation, and vaccine storage.

[0022] As shown in Figures 11 and 12, this embodiment is an example in which the number of intermediate layers and buffers 2 are each two. In addition, the inner wall portion 12 and the inner layer 4 are sealed at their adjacent sides, that is, two buffers 2 are placed between each layer that is not connected to each other, and the inner wall portion 12 and the inner layer 4 are sealed on all four sides, thereby realizing another different configuration. Furthermore, in this invention, as another example, the outer surface 21 and the inner wall portion 12 are fixed to each other, that is, the buffer 2 is fixed by the side edges of the outer surface 21, the inner layer 4 of the packaging bag 1 and the inner wall portion 12, forming a fixed area 5. With this configuration, displacement of the buffer 2 is suppressed and a decrease in seismic cushioning performance can be prevented.

[0023] As shown in Figure 13, in this embodiment, the packaging bag 1 is provided with at least one handle 15, which makes it easy to carry, prevents the packaging bag 1 from falling, and effectively protects the contents. Furthermore, if the packaging bag 1 does fall, the contents are protected by the buffer 2.
