Description

Technical Field

[0001] This utility model relates to a convenient air column bag with an easy-tear opening, belonging to the technical field of convenient air column bags. Background Technology

[0002] Air column bags (also known as inflatable bags or cushioning air column bags) are a lightweight packaging solution that uses "air" as the core cushioning medium. They are made by heat-sealing multiple layers of co-extruded film (commonly PE+PA structure) into several independent air columns. After inflation, they form a three-dimensional airbag, providing 360° suspension protection for the packaged item. Each air column is isolated from the others and has a built-in miniature check valve. After inflation, the valve automatically locks the air. If any air column is damaged, only local pressure loss occurs, and the overall cushioning performance decreases by less than 10%. In terms of protective performance, logistics efficiency, and environmental protection indicators, they comprehensively surpass traditional foam, pulp molding, and other packaging materials.

[0003] In the existing technology, the air column bag forms a fixed volume air cavity after inflation, which significantly increases its empty volume. This expanded form still needs to occupy a three-dimensional space equivalent to that in the usage state during the recycling stage, resulting in a decrease in the loading rate of the recycling container and a corresponding increase in transportation and storage costs, thus causing inconvenience to subsequent centralized recycling and regeneration. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing air column bags form a fixed-volume air cavity after inflation, which occupies a large space and causes inconvenience for subsequent centralized recycling and regeneration.

[0005] To solve the above problems, this utility model provides a convenient air column bag with an easy-tear opening, including a bag body, and several bag bodies are fixedly connected by plastic sheets;

[0006] It also includes a connecting cavity, which is connected to one side of the corresponding bag body. One side of the connecting cavity is provided with an exhaust hole. A sealing strip is fixedly connected to the side of the connecting cavity on the side of the exhaust hole. The other end of the sealing strip is provided with an insertion post that is inserted into the connecting cavity. An adhesive strip is provided on the side of the sealing strip next to the insertion post.

[0007] Furthermore, the side of the connecting cavity is provided with a plug groove at the corresponding position of the plug post, and the diameter of the plug groove is the same as the diameter of the plug post.

[0008] Furthermore, a snap-fit ​​piece of elastic material is fixedly connected to the lower end of the plug-in post. The snap-fit ​​piece is disc-shaped and its diameter is larger than that of the plug-in groove.

[0009] Furthermore: the side of the connecting cavity is provided with an adhesion groove next to the insertion slot, and the shape of the adhesion groove is the same as that of the adhesion strip.

[0010] Furthermore, adjacent plastic sheets are fixedly connected by a connecting shaft.

[0011] Furthermore, a quick-adhesive strip is fixedly connected to the side of the plastic sheet on one side of each bag body.

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] This patent features a connecting cavity that communicates with the bag body, and a tearable sealing strip structure on the side wall of the connecting cavity. This allows for the rapid and complete release of internal gas during the recycling stage, significantly reducing the three-dimensional space occupied by the air column bag, thereby increasing the loading rate of the recycling container and reducing the transportation and storage costs of centralized recycling and regeneration.

[0014] Meanwhile, an additional adhesive strip is set on the side of the adhesive strip to form a dual retaining force of "mechanical locking + adhesive joint", which can prevent the sealing strip from accidentally coming off due to transportation vibration and ensure airtight stability during use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Combined with appendix Figure 1-4 This utility model provides a convenient air column bag with an easy-tear opening, including a bag body 1, several bag bodies 1 are fixedly connected by plastic sheets 11; it also includes a connecting cavity 2, which is connected to one side of a corresponding bag body 1. One side of the connecting cavity 2 is provided with an exhaust hole 21. A sealing strip 3 is fixedly connected to the side of the connecting cavity 2 near the exhaust hole 21. The other end of the sealing strip 3 is provided with an insertion post 31 that inserts into the connecting cavity 2. An adhesive strip 32 is provided on the side of the sealing strip 3 next to the insertion post 31. The adhesive strip 32 is made of acrylic. The acrylic pressure-sensitive adhesive has an adhesion groove 23 on the side of the connecting cavity 2 next to the insertion groove 22. The shape of the adhesion groove 23 is the same as that of the adhesion strip 32. After the air column bag is inflated, the connecting cavity 2 and the bag body 1 form a connected air cavity. The insertion post 31 at the end of the sealing strip 3 is inserted into the insertion groove 22. The diameter of the disc-shaped elastic snap-fit ​​piece 33 is greater than that of the insertion groove, forming a "mechanical lock" to prevent it from coming loose due to transportation vibration. At the same time, the adhesion strip 32 is pressed into the adhesion groove 23 to form an "adhesive pair". The double holding force is ≥15N, which meets the requirements of long-distance transportation.

[0024] Combined with appendix Figure 1-4 A groove 22 is provided on the side of the connecting cavity 2 at the corresponding position of the insertion post 31. The diameter of the groove 22 is the same as the diameter of the insertion post 31. A TPU elastic snap-fit ​​piece 33 is fixedly connected to the lower end of the insertion post 31.

A quick-adhesive strip 13 is fixedly connected to the side of the plastic piece 11 on one side of each bag body 1. When recycling, pinch the free end of the sealing strip 3 and tear it upwards. The adhesive strip 32 first detaches from the adhesive groove 23, then the insertion post 31 is pulled out, the snap-fit ​​piece 33 elastically contracts, and the sealing strip 3 completely detaches from the vent hole 21 of the connecting cavity 2. The whole process takes less than 2 seconds. The gas inside the bag is quickly released through the vent hole 21. After venting, the bag body 1 can be folded and then glued together with the quick-adhesive strip 13 to form a stack, preventing loose stacking and taking up space, and making it easy to carry.

[0025] The working principle of this application is as follows:

[0026] After the air column bag is inflated, the connecting cavity 2 and the bag body 1 form a connected air cavity. The end of the sealing strip 3, the insertion post 31, is inserted into the insertion groove 22. The diameter of the disc-shaped elastic snap-fit ​​piece 33 is greater than 0.5mm of the insertion groove 22, forming a "mechanical lock" to prevent it from coming loose due to transportation vibration. At the same time, the adhesive strip 32 is pressed into the adhesive groove 23 to form an "adhesive pair". The double holding force is ≥15N, which meets the requirements of long-distance transportation. When recycling, pinch the free end of the sealing strip 3 with your fingers and tear it upwards.
