Description

Technical Field

[0001] This utility model belongs to the technical field of cushioning air column bags, specifically a cushioning air column bag structure. Background Technology

[0002] Air column bags are a new type of packaging material that is increasingly widely used as cushioning packaging. They utilize natural air filling, maximizing resource conservation and reducing waste, and are widely used in the transportation and storage of various products. Their main characteristics include shock resistance, pressure resistance, good sealing, and environmental recyclability. Air column bags form multiple air columns when inflated, which effectively absorb vibrations and impacts generated during transportation, thus protecting products from damage. The material of air column bags is typically made of multi-layer extruded film, possessing good tensile strength and uniformity. Before inflation, air column bags are flat and thin, taking up little space and facilitating storage and transportation, significantly reducing logistics and warehousing costs. After inflation, the air column bags can be punctured to release air, making them easy to recycle. Air column bags have a wide range of applications, suitable for multiple industries such as electronics, home appliances, and pharmaceuticals.

[0003] Current air column bags primarily employ a uniform air column diameter and a single inflation pressure. This type of air column bag is suitable for products with good internal structural strength, uniform weight distribution, and low requirements for packaging cushioning performance. However, it is unsuitable for valuable products with complex internal structures, uneven weight distribution, and high requirements for packaging cushioning performance. For products with uneven weight distribution and high requirements for packaging cushioning performance, the current air column bag with a uniform air column diameter and a single inflation pressure cannot effectively reinforce specific areas of the product. The only way to adjust the support is to increase the number of air column layers. This method increases the material consumption of the air column bag and the overall size of the formed air column bag, which is not conducive to lightweight packaging and results in resource waste.

Obviously, the following described embodiments are only some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present patent, all other embodiments obtained by those skilled in the art without creative labor also belong to the protection scope of the present patent.

[0027] As shown in Figure 1 The present application discloses a buffering air column bag structure, which comprises:

[0028] A plurality of air columns arranged side by side, the length direction of the air column is in front-back direction, and adjacent air columns are separated by heat sealing; the air column comprises a plurality of high-pressure air columns 3 and a plurality of low-pressure air columns 4;

[0029] A high-pressure air inlet channel 1 and a low-pressure air inlet channel 2 are respectively arranged at two ends of the air column;

[0030] The high-pressure air inlet channel 1 is communicated with a plurality of high-pressure air columns 3 through an air valve film, and one end of the high-pressure air column 3 away from the high-pressure air inlet channel 1 is sealed.

[0031] The low-pressure air inlet channel 2 is communicated with a plurality of low-pressure air columns 4 through an air valve film, and one end of the low-pressure air column 4 away from the low-pressure air inlet channel 2 is sealed.

[0032] The buffer air column bag structure can arrange the positions of the high-pressure air column 3 and the low-pressure air column 4 as needed, fill high-pressure gas into the high-pressure air column 3 through the high-pressure air inlet channel 1, fill low-pressure gas into the low-pressure air column 4 through the low-pressure air inlet channel 2, and achieve different packaging protection effects. It can be flexibly applied to valuable products with complex internal structure, uneven weight distribution and high buffering performance requirements, effectively solves the problems of single buffering effect and poor adaptability of traditional air column bags, can adapt to the packaging and protection needs of different types of products, greatly expands the application scenarios of air column bag packaging, and further promotes the realization of green packaging. The overall structure is simple, the layout is reasonable, the realization is easy, and the practicality is good.

[0033] Further, according to the structural characteristics of the packaged product, the high-pressure air column 3 and the low-pressure air column 4 can be arranged individually, or multiple and individually, or individually and multiple, to achieve flexibility and good adaptability.

[0034] According to the width relationship of the high-pressure air column 3 and the low-pressure air column 4, the following multiple embodiments can be provided:

[0035] In one embodiment, the high-pressure air column 3 and the low-pressure air column 4 are designed to have equal widths. After inflation and molding, the high-pressure air column 3 and the low-pressure air column 4 are in contact with the product (for flat products), the low-pressure air column 4 is arranged in a place where the product weight distribution is small, and the high-pressure air column 3 is arranged in a place where the product weight distribution is large, which can balance the compression amount of the air column bag during impact and reduce damage such as distortion caused by uneven stress on the product.

[0036] In another embodiment, the high-pressure air column 3 has a smaller width than the low-pressure air column 4. After inflation and molding, the low-pressure air column 4 has a larger diameter than the high-pressure air column 3, the low-pressure air column 4 is in direct contact with the product (for flat products), and the high-pressure air column 3 maintains a certain distance from the product. When impacted, the low-pressure air column 4 in direct contact with the product first plays a buffering role to reduce impact stress, and after the low-pressure air column 4 is compressed, the product comes into contact with the high-pressure air column 3, the high-pressure air column 3 plays a supporting role to reduce buffering compression, which is beneficial to reducing the overall packaging size.

[0037] In another embodiment, the high-pressure air column 3 has a width greater than the width of the low-pressure air column 4. After the inflation molding, the diameter of the low-pressure air column 4 is smaller than the diameter of the high-pressure air column 3, the high-pressure air column 3 is directly in contact with the product (for a planar product), and plays a major buffering role, and a greater range of impact response G value adjustment effect is obtained.

[0038] As shown in Figure 1 , the high-pressure air inlet channel 1 and the low-pressure air inlet channel 2 are respectively arranged vertically to the air column. It is convenient for manufacturing and molding to form an air column bag structure in the shape of a rectangle, and it is widely and conveniently applied.

[0039] On the other hand, the overall air column bag shape can also be designed according to the shape of the packaging surface, so that the high-pressure air inlet channel 1 and the low-pressure air inlet channel 2 are arranged at a flexible angle with the air column, and the use is more flexible and convenient.

[0040] Further, as shown in Figure 1 , one end of the high-pressure air inlet channel 1 is an inflation port, and the other end is sealed by a high-pressure air inlet channel sealing port 11, that is, a high-pressure air inlet channel sealing port 11 is formed by heat sealing, so as to facilitate inflation of the high-pressure air column 3 from the one end inflation port; one end of the low-pressure air inlet channel 2 is an inflation port, and the other end is sealed by a low-pressure air inlet channel sealing port 21, that is, a low-pressure air inlet channel sealing port 21 is formed by heat sealing, so as to facilitate inflation of the low-pressure air column 4 from the one end inflation port.

[0041] Among them, as shown in Figures 1-2 , the high-pressure air column 3 is provided with high-pressure air column air valve membranes 5 with opposite air inlet directions at both ends, and the high-pressure air column air valve membrane 5 away from the side of the high-pressure air inlet channel 1 is sealed by an air valve membrane sealing port 7.

[0042] Further, the outer surface of the high-pressure air column air valve membrane 5 is not oiled, which facilitates the reliability of heat sealing and bonding with the inner surface of the high-pressure air column 3; the inner surface of the air inlet end (outer end) of the high-pressure air column air valve membrane 5 is oiled, and the inner surface of the air outlet end (inner end) of the high-pressure air column air valve membrane 5 is not oiled. Before heat sealing of the high-pressure air column air valve membrane 5, the high-pressure air column air valve membranes 5 at both ends have the same structure and consistent oiling process, realizing the convenience of processing and molding, and the position of the heat-sealed air valve membrane sealing port 7 is at the air outlet end (not oiled) of the high-pressure air column air valve membrane 5, realizing the reliability of forming the air valve membrane sealing port 7. By oiling the inner surface of the air inlet end of the high-pressure air column air valve membrane 5, when the high-pressure air column 3 is inflated by the high-pressure air inlet channel 1, the air inlet end of the corresponding high-pressure air column air valve membrane 5 can be effectively separated and ventilated, avoiding static adsorption.

[0043] As shown above, the low-pressure air column 4 is provided with low-pressure air column valve membranes 6 with opposite air inlet directions at both ends, and the low-pressure air column valve membrane 6 away from the low-pressure air inlet channel 2 is sealed by a valve membrane seal 7. In order to avoid great changes in the existing production process and ensure the convenience and efficiency of production, the low-pressure air column valve membranes 6 with opposite air inlet directions are provided at both ends, and the low-pressure air column valve membrane 6 close to the low-pressure air inlet channel 2 is not heat sealed, and the low-pressure air column valve membrane 6 away from the low-pressure air inlet channel 2 is heat sealed by the valve membrane seal 7. Figures 1-2 Further, the outer surface of the low-pressure air column valve membrane 6 is not oiled to facilitate the reliability of heat sealing and bonding with the inner surface of the low-pressure air column 4; the inner surface of the air inlet end (outer end) of the low-pressure air column valve membrane 6 is oiled, and the inner surface of the air outlet end (inner end) of the low-pressure air column valve membrane 6 is not oiled. Before heat sealing the low-pressure air column valve membrane 6, the low-pressure air column valve membranes 6 at both ends have the same structure and consistent oiling process, realizing the convenience of processing and molding, and the position of the valve membrane seal 7 formed by heat sealing is at the air outlet end (not oiled) of the low-pressure air column valve membrane 6, realizing the reliability of forming the valve membrane seal 7. The inner surface of the air inlet end of the low-pressure air column valve membrane 6 is oiled, and when the low-pressure air column 4 is inflated through the low-pressure air inlet channel 2, it can effectively ensure that the air inlet end of the corresponding low-pressure air column valve membrane 6 can be separated and ventilated, avoiding static adsorption.

[0044] The buffer air column bag structure can arrange the positions of the high-pressure air column 3 and the low-pressure air column 4 as needed, inflate the high-pressure air column 3 with high-pressure gas through the high-pressure air inlet channel 1, and inflate the low-pressure air column 4 with low-pressure gas through the low-pressure air inlet channel 2, realizing different packaging protection effects, and being flexibly applicable to valuable products with complex internal structures, uneven weight distribution, and high buffering performance requirements, effectively solving the problems of single buffering effect and poor adaptability of traditional air column bags, adapting to the packaging and protection needs of different types of products, greatly expanding the application scenarios of air column bag packaging, and further promoting the realization of green packaging. The overall structure is simple, the layout is reasonable, the realization is easy, and the practicality is good.
