TECHNICAL FIELD

[0001] The present application relates to the field of air column bags, in particular to an anti-wringing air column bag. BACKGROUND

[0002] The air column bag is also called a buffer air column bag or an air-filled bag, which is a new type of patented packaging material filled with natural air. It is the most economical and environmentally friendly buffer packaging material. The air column bag uses a comprehensive air column for buffer protection and pressure dispersion to reduce the product transportation loss rate to the minimum.

[0003] In the prior art, when the air column bag is produced, gas is injected into a sealed plastic bag to form an air bag structure of a certain structure, which can effectively reduce the shock protection effect of the product.

[0004] However, in the traditional air column filling process, if the air column is not filled enough, the air column bag will have poor buffering effect. If the user operates carelessly, the air column bag will always be overfilled and the air column will be burst, causing the air column bag to be scrapped, thereby causing waste of the air column bag. Therefore, the present application provides an anti-wringing air column bag to solve the above problems. SUMMARY

[0005] The present application aims to provide an anti-wringing air column bag to solve the problems of poor buffering effect of the air column bag if the air column is not filled enough, and the air column bag will always be overfilled and the air column will be burst, causing the air column bag to be scrapped, thereby causing waste of the air column bag.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme: an anti-wringing air column bag, comprising: an upper air column body, a lower air column body arranged below the upper air column body, the upper air column body and the lower air column body being composed of a first film and a second film, the first film and the second film being sealed and connected by a leak-proof heat sealing strip, and a gas inlet channel being arranged between the upper air column body and the lower air column body.

[0007] A buffer assembly is arranged inside the first film and the second film, and the buffer assembly comprises a buffer strip, an upper adapter, a fastener, a lower adapter and a film body.

[0008] Preferably, the upper end of the first film and the second film is provided with an upper heat sealing strip, the left side of the first film and the second film is provided with a left heat sealing strip, and the right side of the first film and the second film is provided with a right heat sealing strip.

[0009] Preferably, the gas inlet channel is located below the upper heat sealing strip, one side of the gas inlet channel is in an open state to form a gas injection port, and a gas valve film heat sealing strip is arranged below the gas inlet channel. Each air column body is provided with a one-way gas valve film at the gas valve film heat sealing strip, and each one-way gas valve film is communicated with the gas inlet channel.

[0010] Preferably, a main air transmission hole and a secondary air transmission hole are provided below the air intake channel. The main air transmission hole and the secondary air transmission hole are evenly distributed on the surface of the air intake channel. An inflation chamber is provided next to the air intake channel, and a buffer assembly is provided in the inflation chamber.

[0011] Preferably, the firmware is fixedly connected to the leak-proof heat seal strip. An upper connector is fixed to the upper end of the firmware, a lower connector is fixed to the lower end of the firmware, and a film body is fixed to the end of the lower connector. There are two sets of firmware, upper connector and lower connector, and the two sets of firmware, upper connector and lower connector are symmetrically distributed about the film body.

[0012] Preferably, the buffer assembly is provided in a plurality of units, which are linearly distributed at equal intervals within the inflation chamber.

[0013] Preferably, the upper connector has a buffer strip inside, the buffer strip and the upper connector are slidably adapted, the lower end of the buffer strip is fixed with a connecting strip, the surface of the buffer strip is fixed with a slider, and the inner surface of the second film is provided with a guide rail, the slider and the guide rail are slidably adapted.

[0014] Preferably, the lower connector is provided with a spring inside, one end of the spring is fixed to an upper movable disk, and the other end of the spring is fixed to a lower movable disk. Both the upper and lower movable disks are slidably connected to the lower connector. An upper sealing sleeve is fixed to the surface of the upper movable disk, and a lower sealing sleeve is fixed to the surface of the lower movable disk.

[0015] Preferably, the surface of the lower connector has a through hole, and the connector strip passes through the fastener and is fixedly connected to the upper movable disk.

[0016] Preferably, the film body is connected to the first film via connecting strips. There are two sets of connecting strips, which are located on both sides of the lower end of the film body. An air storage cavity is provided inside the film body, and the air storage cavity is connected to the lower connector.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention proposes an anti-crumpling air column bag. During inflation, air is introduced into the inflation chamber through the air inlet channel, allowing simultaneous inflation of the upper and lower air columns. When the gas in the inflation chamber is nearly saturated, the gas compresses the film, filling its interior with gas. This gas then compresses the lower moving plate, causing the spring to move. This, in turn, moves the upper moving plate, which in turn pushes the connecting strip and the buffer strip. When the user observes the moving strip moving to the middle of the air column, they know that the air column is fully inflated. This reduces the possibility of the air column bag bursting due to over-inflation, improving the processing efficiency of the air column bag. This avoids the problems of traditional air column inflation, where insufficient inflation leads to poor cushioning, and over-inflation by the user often results in the air column bursting, causing the air column bag to be scrapped and wasted.

In the following description, numerous specific details are set forth to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures have not been described in detail to avoid unnecessarily obscuring these embodiments. Furthermore, all embodiments can be used in combination with each other.

[0032] Example 1

[0033] Please see Figures 1 to 8The present invention provides a technical solution: an anti-rubbery air column bag, the anti-rubbery air column bag comprising: an upper air column 30, a lower air column 29 disposed below the upper air column 30, the upper air column 30 and the lower air column 29 being composed of a first film 5 and a second film 27, the first film 5 and the second film 27 being sealed together by a leak-proof heat seal strip 9, and an air inlet channel 2 being provided between the upper air column 30 and the lower air column 29;

[0034] A buffer assembly 100 is disposed inside the first film 5 and the second film 27. The buffer assembly 100 includes a buffer strip 14, an upper connector 15, a fastener 16, a lower connector 18, and a film body 28. The upper end of the first film 5 and the second film 27 is provided with an upper heat-sealing strip 1, the left side of the first film 5 and the second film 27 is provided with a left heat-sealing strip 4, and the right side of the first film 5 and the second film 27 is provided with a right heat-sealing strip 6.

[0035] The upper connector 15 is provided with a buffer strip 14 inside. The buffer strip 14 and the upper connector 15 are slidably adapted. The lower end of the buffer strip 14 is fixed with a connecting strip 25. The surface of the buffer strip 14 is fixed with a slider 13. The inner surface of the second membrane 27 is provided with a guide rail 26. The slider 13 and the guide rail 26 are slidably adapted.

[0036] The lower connector 18 is provided with a spring 20. One end of the spring 20 is fixed to an upper moving disk 21, and the other end of the spring 20 is fixed to a lower moving disk 23. The upper moving disk 21 and the lower moving disk 23 are slidably connected to the lower connector 18. An upper sealing sleeve 22 is fixed to the surface of the upper moving disk 21, and a lower sealing sleeve 24 is fixed to the surface of the lower moving disk 23.

[0037] During inflation, air is introduced into the inflation chamber 8 through the air inlet channel 2, thereby simultaneously inflating the upper air column 30 and the lower air column 29. When the gas in the inflation chamber 8 is nearly saturated, the gas compresses the diaphragm 28, which is filled with gas. At this time, the gas inside the diaphragm 28 compresses the lower moving plate 23, causing the spring 20 to move. This, in turn, moves the upper moving plate 21, which in turn pushes the connecting strip 25 and the buffer strip 14 to move. When the user observes the moving strip moving to the middle of the air column... This indicates that the air column is fully inflated, reducing the possibility of the air column bag bursting due to over-inflation and improving the processing efficiency of the air column bag. When the buffer strip 14 moves, it will move along the inner surface of the second film 27 because the slide strip 13 and the guide rail 26 are slidably adapted, thus facilitating the observation of the position of the buffer strip 14. The first film 5 and the second film 27 are connected by the leak-proof heat-sealing strip 9, improving the airtightness of the air column bag. At the same time, the leak-proof heat-sealing strip 9 is connected to the fastener 16, improving the stability of the buffer assembly 100.

[0038] Example 2

[0039] In order to improve the gas delivery efficiency of the air column bag, an air inlet channel 2 is provided based on the first embodiment. A main air transmission hole 11 and a secondary air transmission hole 10 are provided below the air inlet channel 2. The main air transmission hole 11 and the secondary air transmission hole 10 are evenly distributed on the surface of the air inlet channel 2. An inflation chamber 8 is provided next to the air inlet channel 2, and a buffer assembly 100 is provided in the inflation chamber 8.

[0040] During the gas supply operation, the gas enters the main air transmission port 11 and the secondary air transmission port 10 through the air intake channel 2. Since the main air transmission port 11 and the secondary air transmission port 10 connect the upper air column 30 and the lower air column 29, the upper and lower air columns can be filled at the same time, thereby improving the filling efficiency.

[0041] Example 3

[0042] In order to improve the stability of the film body 28 in the inflation chamber 8, a connecting strip 19 is provided based on the second embodiment. The film body 28 is connected to the first film 5 through the connecting strip 19. There are two sets of connecting strips 19, which are located on both sides of the lower end of the film body 28. The surface of the lower connecting member 18 is provided with a through hole 17. The upper moving disk 21 and the lower moving disk 23 are slidably connected to the lower connecting member 18. The surface of the upper moving disk 21 is fixed with an upper sealing sleeve 22, and the surface of the lower moving disk 23 is fixed with a lower sealing sleeve 24.

[0043] The membrane body 28 is fixed to the inner side of the first membrane 5 by the two connecting strips to prevent the membrane body 28 from shifting or loosening. When the spring 20 moves in the lower connector 18, the lower sealing sleeve 24 can seal the air and prevent the gas inside the gas storage chamber 12 from leaking out. The through hole 17 is located in the middle of the position of the spring 20. The through hole 17 facilitates the output of gas inside the spring 20 when the spring 20 moves, ensuring the smooth movement of the spring 20.

[0044] Working principle: In actual use, during the inflation process, air is injected into the inflation chamber 8 through the air inlet channel 2, thereby simultaneously inflating the upper air column 30 and the lower air column 29. When the gas in the inflation chamber 8 is close to saturation, the gas will compress the diaphragm 28, which is filled with gas. At this time, the gas inside the diaphragm 28 will compress the lower moving plate 23, causing the spring 20 to move. This, in turn, drives the upper moving plate 21 to move, which in turn pushes the connecting strip 25 and the buffer strip 14 to move. When the user observes that the moving strip has moved to the middle of the air column, it can be known that the air column is full. This reduces the possibility of the air column bag bursting due to over-inflation and improves the processing efficiency of the air column bag. This avoids the problem of poor cushioning effect of the air column bag when it is under-inflated during the traditional inflation process. If the user is not careful, over-inflating the air column bag will always burst the air column, causing the air column bag to be scrapped and wasting the air column bag.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
