Description

Displacement stacked air packing device

technical field

The invention relates to an air-packing device and a manufacturing method thereof, in particular to a dislocation stacked air-packing device and a manufacturing method thereof.

Background technique

In the modern logistics industry, the most widely used is the packing box (packing box). However, the packaging methods of this traditional packaging box do not provide anti-collision, anti-collision and anti-drop functions. That is to say, during transportation or storage, the packaging box or crate will be thrown around, which can easily cause its deformation, which may cause damage or deformation of the packaged items. Therefore, for some items with high packaging requirements, such as electronic digital products, plastic ceramics, biochemical products, food and medicine, etc., it is necessary to provide cushioning for the packaged items to prevent the packaged items from being damaged during transportation and storage. Existing solutions, such as traditional paper packaging boxes, can be filled with cushioning materials such as foam materials inside the paper packaging boxes to achieve the purpose of providing cushioning. However, shipping and storage of such boxes and filled cushioning material to the packaging location is very expensive. Moreover, the buffer foam material pollutes the environment and is not environmentally friendly.

Another improvement is the inflatable packaging bag currently available on the market, which is formed by a series of heat-sealing processes of four layers of film, in which an inflatable chamber is formed between two layers of outer film, and a one-way inflation valve is formed between two layers of inner film. It is used to fill the corresponding inflatable chamber with gas and prevent the gas in the inflatable chamber from leaking out. The two outer layers of film are folded a series of times to form a chamber that can accommodate packaged items. In this way, the packaged items can be cushioned by the inflatable packaging bag on all sides to prevent external impact stress from acting on the packaged items. Damage to packaged items. However, the cushioning performance of the single-layer air-filled packaging bag formed by two layers of outer film is still limited. The side wall cannot restore its shape in time, causing the impact stress to be too concentrated locally, so that the stress is transmitted to the packaged items, causing damage to the packaged items.

In this way, the bottom sidewall and surrounding sidewalls of the inner air-packing main body 1 and the corresponding sidewalls and surrounding sidewalls of the outer air-packing main body 2 are superimposed on each other, thereby forming a superimposed structure. And further, taking the left side of the entire air-packing device as an example, the inner left side wall 1c of the inner air-packing main body 1 and the outer left side wall 2c of the outer air-packing main body 2 are dislocated Arranged so as to form an offset laminated structure on the left side of the air-packing device of the present invention.

It is worth mentioning that the structure of the multiple side walls formed by the above-mentioned inner and outer inflatable packaging bodies 1 and 2 is only an example. In practical applications, for the above-mentioned inner and outer inflatable packaging bodies 1 and 2, The side walls may be increased or decreased, for example the top side wall may be increased or one of the peripheral or bottom walls may be decreased. More specifically, for example, the inner air-filled package body 1 includes an inner air-filled bottom wall and two inner air-filled side walls extending from the inner air-filled bottom wall. Correspondingly, the outer inflatable packaging body 2 may also include an outer inflatable bottom wall and two outer inflatable side walls extending from the outer inflatable bottom wall. In another example, the inner air-packing main body 1 and the outer air-packing main body 2 each have two inflatable side walls that are connected to each other and arranged in a dislocation and overlapping manner, without forming an obvious bottom wall. That is to say, the two inflatable side walls which are connected to each other and arranged in an offset superposed manner are integrally connected at the bottom. It is worth mentioning that, in this preferred embodiment, the inner air-packing main body 1 forms an inner bag with the accommodating cavity 100, and the outer air-packing main body 2 also forms an outer bag with an accommodating space, The inner air-packing main body 1 extends into the accommodating space of the outer bag formed by the outer air-packing main body 2, thereby forming a bag-in-bag structure. Of course, the present invention is not limited in this respect, and in practical applications, other structures are also possible, instead of forming a completely regular bag structure.

In this preferred embodiment of the present invention, the inner layer inflatable unit 1111 of the inner layer inflatable packaging body 1 is misplaced from the outer layer inflatable packaging body 2 and the outer layer inflatable unit 1112, so as to enhance the Cushioning performance of the air-packing device of the invention. The inner layer inflatable unit 1111 of the inner layer inflatable packaging body 1 and the outer layer inflatable unit 1112 of the outer layer inflatable packaging body 2 are misplaced so that the inner layer inflatable unit 1111 and the outer layer A buffer space is formed between the inflatable units 1112, so that the impact stress applied to the outer layer inflatable unit 1112 will not be directly transmitted to the articles to be packaged, but will provide the outer layer inflatable unit 1112 with predetermined pressure through the buffer space. Cushioning effect, then the inner layer inflatable unit 1111 further provides a cushioning effect, so as to effectively disperse impact stress.

When the outer layer inflatable unit 1112 is subjected to impact stress, the air in the outer layer inflatable unit 1112 will be temporarily distributed to the inner layer inflatable unit 1111, but the buffering and restoring force of the inner layer inflatable unit 1111 will make the air Return to the outer layer inflatable unit 1112 to restore the outer layer inflatable unit 1112 to its original state, thus ensuring that the air will not be too concentrated in a specific area. The overlapping arrangement of the outer layer inflatable unit 1112 and the inner layer inflatable unit 1111 enhances its recovery performance, thereby providing more effective cushioning performance.

In addition, the position of the separation seam 1031 of the inner air-filled packaging body 1 is a non-inflatable structure, and the cushioning capacity is relatively weak, while the outer air-filled packaging body 2 corresponding to the position of the separation seam 1031 of the inner air-filled packaging body 1 It is the inflatable structure formed by the outer inflatable unit 1112, which has a strong buffering effect; similarly, the position of the separation seam 1032 of the outer inflatable packaging body 2 is a non-inflatable structure, and the buffering capacity is relatively weak, while corresponding to the The inner inflatable packaging main body 1 at the position of the separation seam 1032 of the outer inflatable packaging main body 2 is an inflatable structure formed by the inner inflatable unit 1111, which has a strong buffering effect. The layers of air-packing main bodies 1 and 2 improve the cushioning performance on all sides of the entire air-packing device, and can ensure that the cushioning performance on all sides is basically uniform.

It is worth mentioning that, in this preferred embodiment of the present invention, the separation seam 103 is formed by three parts, the separation seam 1031 between the adjacent inner layer inflatable units 1111, the separation seam 1031 between the adjacent outer layer inflatable units 1112 The separation seam 1032, and the turning seam 31. In this preferred embodiment, the turning seam 31 integrally and obliquely extends between the separation seam 1031 between the inner layer inflatable units 1111 and the separation seam 1032 between the outer layer inflatable units 1112 .

In the present invention, the apex positions of the inner layer inflatable unit 1111 and the outer layer inflatable unit 1112 are respectively staggered, so that the thickness of the stacked inner layer inflatable unit 1111 and the outer layer inflatable unit 1112 can be increased. decrease. Moreover, the separation seam 1031 between the inner layer inflatable units 1111 corresponds to the main body of the outer layer inflatable unit 1112, so that when heat conduction and heat radiation are transferred to the separation seam 1031, it will be absorbed by the outer layer inflatable unit. The air inside 1112 is blocked to further prevent heat transfer. And the separation seam 1032 between the outer layer inflatable units 1112 corresponds to the main body of the inner layer inflatable unit 1111, so that when heat conduction and heat radiation are transferred to the separation seam 1032, it will be absorbed by the inner layer inflatable unit. The air inside 1111 is blocked to further prevent the transfer of heat, so that the dislocation stacked air-packing device of the present invention can also be suitable for packaging of items to be packaged that require heat preservation.

In this preferred embodiment of the present invention, taking the case where the inner air-packing main body 1 and the outer air-packing main body 2 respectively form three side walls, the inner air-filled unit 1111 can further be an inner layer The bottom wall inflatable unit 1111a and the inner sidewall inflatable units 1111b and 1111c, the outer inflatable unit 1112 can further be the outer bottom wall inflatable unit 1112a and the outer sidewall inflatable units 1112b and 1112c. Wherein, the inner bottom wall inflatable unit 1111a and the outer bottom wall inflatable unit 1112a are arranged in a dislocation stack, and the inner side wall inflatable unit 1111b and the outer side wall inflatable unit 1112b are in a dislocation stack. Arranged layer by layer, the inner side wall inflatable unit 1111c and the outer side wall inflatable unit 1112c are arranged in a stacked and misplaced manner, so that the entire inner layer inflatable packaging body 1 and the outer layer inflatable packaging body 2 form a Arranged in staggered layers to enhance its cushioning performance.

The inner air-packing main body 1 is integrally connected to the outer air-packing main body 2 through a turning portion 30 , so as to position the packaged items when used for packaging the packaged items, thereby strengthening the cushioning effect. More specifically, when the packaged items are stored in the packaging device of the present invention and during transportation, when the entire air-packed device shakes due to impact, the packaged items will not be concentrated in the air due to the pulling effect of the inner air-filled packaging main body 2 a local location. Specifically, for example, when the packaged items want to shake to the right corner, the left side of the inner air-packing main body 1 of the air-packing device of the present invention is connected to the outer outer air-packing main body 2, so that its The pulling action will cause the packaged item to return to its original position. That is to say, when the packaged items are stored in the inner air-packing main body 1 of the air-packing device, they will always tend to remain in a fixed position, and keep a predetermined distance from the outer air-packing main body 2 on the outside without direct contact. , so that the stress applied to the outer air-tight packaging body 2 on the outside can be evenly distributed through the sealed air chamber, and will not be directly transmitted from the sealed air chamber of the outer air-filled packaging body 2 to the packaged items.

On the other hand, since the inner air-packing main body 1 of the present invention is connected and fixed to the outer air-packing main body 2 outside, this makes the gap between the inner air-packing main body 1 and the outer air-packing main body 2 of the present invention There will be a predetermined amount of air in the buffer space. When the outer inflatable package body formed by the inflatable three-dimensional package is impacted and impacted, the buffer space between the inner inflatable package body 1 and the outer inflatable package body 2 and the predetermined amount of air also form a layer of air chamber structure 3, so as to help play a cushioning role, and separate the packaged items from the sealed air chamber of the outer air-filled packaging body 2, thereby preventing the Impact forces are transmitted directly to the packaged item. In this way, through the air cushioning effect between the inner air-packing body 1 and the outer air-packing body 2, the arrangement of two layers of offset air-packing bodies also enhances the cushioning function of the air-packing device of the present invention.

It is worth mentioning that the reliability of the packaging is also increased due to the addition of an inner layer of the air-filled packaging body 1 that is displaced in the outer layer of the air-filled packaging body 2 . For example, when a certain inflatable unit 11 is damaged, because of the misplaced laminated structure of the present invention, the adjacent outer layer inflatable packaging body 2 and the inner layer inflatable packaging body 1 still have a single layer near the position of the damaged inflatable unit 11. Cushioning structure so that there is still an inflated cushioning effect.

In addition, the end inflatable units 1113 at both ends of the outer and inner inflatable packaging bodies 2 and 1 are also connected by end seams 114, while the inner inflatable packaging body 1 is also provided with inner seams 115, which The side buffer units 1114 are sealed together to provide a buffer space between the side buffer unit 1114 and the end inflatable unit 1113, so that the side inflatable units also form a laminated structure, thereby having a strong elastic recovery Force, thereby enhancing the side cushioning performance of the entire air-packing device.

More specifically, for example, the end seams 114 include an inner front sidewall end seam 1141, an inner back sidewall end seam 1142, an outer front sidewall end seam 1143, and an outer front sidewall end seam. Seam 1144. When forming a double-layer structure, the inner layer front side wall end seam 1141 and the inner layer rear side wall end seam 1142 are formed by heat sealing once, so that the inner layer inflatable packaging main body 1 forms two layers. side walls 1c and 1d. The outer front side wall end seam 1143 and the outer front side wall end seam 1144 are formed by heat sealing once when forming a double-layer structure, so that the outer air-filled packaging main body 2 forms two sides. Walls 2c and 2d. It is worth mentioning that the inner layer front side wall end seam 1141 and the inner layer rear side wall end seam 1142 can also integrally extend to the inner layer bottom wall 1e, and the outer layer front side wall The end seam 1143 and the outer rear side wall end seam 1144 may also integrally extend to the outer bottom wall 2e.

The inner seam 115 is arranged between the two inner layer inflatable units 1111 on the left and right sides of the inner layer inflatable packaging main body 1, so as to form a superimposed structure of the inflatable units on the left and right sides respectively, so as to strengthen the left and right sides buffer performance. In some embodiments, the end inflatable unit 1113 of the inner air-packing main body 1 adjacent to the inner seam 115 may also form an inflatable structure, so as to provide a buffer space to enhance the shrinkage of the side air chambers.

In addition, the inflatable body 10 further includes a main channel sealing seam 116 and an end sealing seam 117 , which are formed by heat sealing the first and last ends of the two air chamber layers of the inflatable body 10 respectively. In the actual manufacturing process, the main channel sealing seam 116 and the end sealing seam 117 can also be formed by one heat sealing, and in this preferred embodiment, the inner air-packing main body 1 and the The outer air-packing main body 2 is heat-sealed together through the main channel sealing seam 116 and the end sealing seam 117, and the heat-sealing position is located on the front or rear side walls of the two-layer air-packing main body, such as the The main channel sealing seam 116 and the heat sealing of the end sealing seam 117 are used to connect the front side wall 1 a of the inner air-packing main body 1 and the front side wall 2 a of the outer air-packing main body 2 .

It is worth mentioning that each of the inner and outer air-packing main bodies 1 and 2 also includes two folding units 40 respectively located at the two corners of the inflated air-packing device, so that the formed The corners of the air-cushioned packaging bag are easy to fold, which facilitates the formation of a three-dimensional configuration. In addition, the bottom wall may be arranged approximately at right angles to the four surrounding walls, so as to form a regular rectangular or square receiving space between the bottom wall and the four surrounding walls. The arrangement of the folding unit 40 facilitates the formation of two side walls 1c and 1d of the inner air-packing main body 1, and the formation of two side walls 2c and 2d of the outer air-packing main body 2, and these side walls are respectively connected with the corresponding A substantially right angle is formed between the adjacent bottom wall and the front and rear side walls, so that the entire air-packing device is suitable for accommodating substantially square items to be packaged.

Each of the folding units 40 can be realized by setting a plurality of exhaust slits 401 in the corresponding sub-air chamber units 111, and these exhaust slits 401 reduce the inflation amount of the corresponding sub-air chamber units 411, thereby facilitating the whole The folding of the folding unit 30 . The air vent 401, for example, can be formed by heat sealing, and its shape, size, position, etc. are not limited, for example, it can be a plurality of heat sealing lines or heat sealing blocks arranged horizontally or vertically. It is worth mentioning that the folding unit 40 can protrude from the outside of the offset stacked air-packing device, or can be inserted into the inside of the offset stacked air-packing device as shown in FIG. 7 .

In another embodiment, as shown in Fig. 9 and Fig. 10, the folding unit 40' can also be a non-inflatable unit, and a communication channel 113 is provided to realize gas distribution. In addition, the sub-air chamber units of each of the inner and outer air-filled packaging bodies 1 and 2 may have different sizes and diameters, so as to adapt to the shape and size of the items to be packaged. Moreover, the sub-air chamber units with different sizes and diameters can realize multi-level cushioning, thereby also enhancing the cushioning performance of the entire air-packing device. In this preferred embodiment, the side of the inner air-packing main body 1 has a large-diameter air chamber 1115, so that the side wall of the inner air-packing main body 1 is roughly arc-shaped, so as to better match the The items to be packaged fit together, and can also play a role in tightening the opening.

Fig. 11 to Fig. 15 are the misplaced laminated air-packing device according to the second preferred embodiment of the present invention. The structure of the device is more suitable for packaging flat or thin items to be packaged.

Similarly, it includes an inner air-packing main body 1A and an outer air-packing main body 2A, which are superimposed on each other and arranged in a dislocation manner, so as to enhance the cushioning performance of the peripheral wall of the dislocation stacked air-packing device. The inner air-packing main body 1A and the outer air-packing main body 2A can be separate inflatable structures, which are connected into an integral structure by means of heat sealing or the like, or can be the inner air-packing main body 1A and the The outer inflatable packaging main body 2A is an integrated structure. In this preferred embodiment of the present invention, taking the integrated structure as an example, the inner inflatable packaging main body 1A and the outer inflatable packaging main body 2A are integrally formed by an inflatable main body 10A form. Of course, the integral structure formed by the inner air-packing main body 1A and the outer air-packing main body 2A also has a dislocation laminated structure, so that the cushioning performance of the entire dislocated laminated air packaging can be enhanced.

The inflatable main body 10A further includes two turning parts 30A, and the inner air-packing main body 1A or the outer air-packing main body 2A is formed between the two turning parts 30A. The inner air-packing main body 1A and the outer air-packing main body 2A are superimposed on each other and arranged in a dislocation manner, so as to enhance the cushioning performance of the peripheral wall of the dislocation stacked air-packing device.

It can be seen from the figure that the inner inflatable unit 1111 of the inner inflatable packaging body 1A and the inner inflatable unit 1111 of the outer inflatable packaging body 2A are arranged without overlapping, more specifically, the inner The position of the separation seam 1031A between the inner layer inflatable units 1111 of the layer inflatable packaging main body 1A and the separation seam 1032A between the inner layer inflatable units 1111 of the outer layer inflatable packaging body 2A are not overlapped, but misplaced. Arrangement, the inner layer inflatable unit 1111 of the inner layer inflatable packaging body 1 is partially overlapped with the inner layer inflatable unit 1111 of the outer layer inflatable packaging body 2A instead of being securely overlapped, thereby forming the present invention of the dislocation structure.

For example, in this preferred embodiment, the inner air-packing main body 1A forms an inner front side wall 1a', an inner rear side wall 1b', and an inner bottom side wall 1e' and forms an accommodating cavity for storing items to be packaged, so The outer air-packing main body 2A forms an outer front side wall 2a', an outer rear side wall 2b' and an outer bottom side wall 2e'. Taking the entire front side of the air-packing device as an example, the inner front side wall 1a' of the inner air-packing main body 1A and the outer front side wall 2a' of the outer air-packing main body 2A are arranged in a misaligned manner, Thus, a dislocation stacked structure is formed on the front side of the air-packing device of the present invention. It is worth mentioning that, in this preferred embodiment, when the inner air-packing main body 1A and the outer air-packing main body 2A are heat-sealed together, the main channel sealing seam 116A and the end sealing seam 117A is heat-sealed to connect the outer front side wall 2a' and the outer bottom side wall 2e' of the outer air-filled packaging main body 2A.

In this way, in this preferred embodiment of the present invention, the inner layer inflatable unit of the inner layer inflatable packaging body 1A is arranged in a misaligned manner with the outer layer inflatable packaging body 2A and the outer layer inflatable unit, so as to enhance this Cushioning performance of the air-packing device of the invention. The inner layer inflatable unit of the inner layer inflatable packaging body 1A and the outer layer inflatable unit of the outer layer inflatable packaging body 2A are misplaced so that there is a gap between the inner layer inflatable unit and the outer layer inflatable unit A buffer space is formed between them, so that the impact stress applied to the outer layer inflatable unit will not be directly transmitted to the items to be packaged, but will provide a predetermined buffer effect to the outer layer inflatable unit through the buffer space, and then the The inner air-filled unit further provides a cushioning effect to effectively disperse impact stress.

It is worth mentioning that, in these two embodiments, the length of the sub-inflatable unit of the inner packaging body 1A can be shorter than that of the outer air-packing main body 2A, or it can be roughly the same. When the length of the sub-inflatable unit of the inner air-packing main body 1A is small, there is a predetermined distance between the bottom wall of the inner air-packing main body 1A and the bottom wall of the outer air-packing main body 2A, so that the inner air-packing The main body 1A is suspended in the outer air-filled packaging main body 2A to enhance the bottom cushioning effect. Of course, in other embodiments, after inflation, the outer surface of the bottom wall of the inner air-filled packaging body 1A may also be in contact with the inner surface of the bottom wall of the outer air-filled packaging body 2A.

It is worth mentioning that the above-mentioned various seams such as separation seams, bending seams, turning seams, end seams, inner seams, etc. can be formed by a heat-sealing process, which combines two or more layers of flexible film Heat seal together.

As shown in Fig. 16 and Fig. 17, it is a schematic structural diagram of a staggered stacked air-packing device according to a third preferred embodiment of the present invention. In this preferred embodiment, similarly, the staggered stacked air-packing device It includes an inner air-packing main body 1B and an outer air-packing main body 2B. But the difference is that the outer air-packing main body 2B may not have a bottom wall, but only two side walls 2a" and 2b", and the side walls 2a" and 2b" are arranged at intervals and parallel to each other.

Similarly, the inner air-packing main body 1B is formed by an inner inflatable unit 1111B between two side walls 2a" and 2b", and each of the two turning parts 31B includes a row of bending seams 104B and a line between the turning seams 31B. Between the multiple turning inflatable unit 32B. The turning seam 31B is L-shaped and integrally extends between the separation seam 1031B of the inner air-packing body 1B and the separation seam 1032B of the outer air-packing body 2B.

The inner air-packing main body 1B is also formed with an uninflated air chamber 1116B adjacent to the inner seam 115B, so as to form more cushioning between the inner layer inflatable units 1111B on both sides of the inner seam 115B space, thereby enhancing its lateral elastic recovery force.

Those skilled in the art can understand that the turning seam 31B of the turning portion 30B may also be in other shapes, such as an arc shape, other curved shapes, etc., as long as it can make the inner layer inflatable packaging body 1B and the outer layer It is sufficient that the inflatable units of the inflatable packaging main body 2B can produce a dislocation structure after being stacked into a double-layer or multi-layer structure.

As shown in Fig. 18 and Fig. 19, it is a schematic structural diagram of a dislocation stacked air-packing device according to a modified implementation of the third preferred embodiment of the present invention. In this preferred embodiment, similarly, the dislocation The laminated air-packing device includes an inner air-packing main body 1C and an outer air-packing main body 2C, but in this embodiment there is no apparent turning portion 30B as in the above-mentioned embodiments. More specifically, the inner air-packing main body 1C and the outer air-packing main body 2C are integrally connected by a transfer seam 31C, and the transfer seam 31C integrally and vertically extends to the separation seam 1031C of the inner air-packing main body 1C and the separation seam 1032C of the outer air-packing main body 2B, and the separation seams 1031C and 1032C are arranged longitudinally along the length direction, and the transfer seam 31C is arranged transversely, so that the transfer seam 31C It is equivalent to forming a bending heat-sealing line between the inner air-packing main body 1C and the outer air-packing main body 2C, so as to facilitate the bonding of the inner air-packing main body 1C and the outer air-packing main body 2C. The bending between the inflatable units creates a double-layer dislocation structure.

As shown in Fig. 20 and Fig. 21, it is a schematic structural diagram of a dislocation stacked air-packing device according to another modified implementation of the third preferred embodiment of the present invention. In this preferred embodiment, similarly, the The misplaced stacked air-packing device includes an inner air-packing main body 1D and an outer air-packing main body 2D. The difference is that the inner air-filling unit 1111D of the inner air-packing main body 1D is arranged alternately with large and small diameter air chambers, and the The outer inflatable units 1112D of the outer inflatable packaging main body 2D are also arranged alternately with large and small diameter air chambers, and the two adjacent turning seams 31D extend in opposite directions. Moreover, in the dislocation structure, the small-diameter inner layer inflatable unit 1111D of the inner layer inflatable packaging body 1D is superposed with the large-diameter outer layer inflatable unit 1112D of the outer layer inflatable packaging body 2D, and the inner layer inflatable packaging body The large-diameter inner inflatable unit 1111D of 1D is stacked with the small-diameter outer inflatable unit 1112D of the outer inflatable packaging body 2D, thereby enhancing the cushioning performance.

In addition, the inflation valve 20 can be arranged in the outer inflation unit 1112D of the outer inflatable packaging main body 2, wherein more inflation valves 20 can be arranged in the outer inflation unit 1112D with a larger diameter. , for example, two inflation valves, and a smaller number of inflation valves 20 may be provided in the outer layer inflation unit 1112D with a small diameter, for example, only one inflation valve 20 .

As shown in FIG. 22, the inflation valve 20 is a one-way inflation valve, which includes two sealing films 21 and 22, which are overlapped and fixed between the two air chamber layers 101 and 102, thereby forming a four-layer structure, An air-filled passage 24 is formed between the two sealing films 21 and 22 . Correspondingly, when the inflatable body 10 is inflated, the two sealing films 21, 22 are bonded together to seal the inflation channel of the air bag, thereby sealing the air in all parts of the inflatable body 10. In the inflatable cavity 12, when the inflatable body 10 includes a plurality of inflatable units 11, a plurality of inflatable valves 20 are correspondingly provided in each of the inflatable units 11 to respectively seal air in each inflatable unit 11. In particular, the first sealing film 21 is overlapped and adhered to the first air chamber layer 101 , and the second sealing film 22 is overlapped and adhered to the second air chamber layer 102 . When inflating the inflatable body 10 , air is guided into the inflation channel 24 formed between the first sealing membrane 21 and the second sealing membrane 22 . When the air bag is inflated, the first sealing film 21 and the second sealing film 22 are bonded to each other to seal the inflation channel 24 of the air bag. In addition, the air pressure in the air bag acts on the two sealing films 21 and 22 , so as to ensure that the two sealing films 21 and 22 are closely bonded to prevent air from leaking out from the air valve 20 . That is to say, the gas valve is a one-way valve, which only allows gas to enter the inflatable body 10 and prevents gas from seeping back out.

The formation of the inflation channel 24 of the inflation valve 20 can be realized by setting a barrier device between the two sealing films 21 and 22, when the two sealing films 21 and 22 are combined with the two air chamber layers 101 and When 102 is heat-sealed, because of the setting of the barrier device, the two sealing films 21 and 22 will not be completely heat-sealed together, thereby forming the inflation channel 24 . In a specific example, the barrier means may be high temperature resistant ink.

The first sealing film 21A and the second sealing film 22A are two thin layers of flexible films made of plastic that overlap each other. Preferably, the first sealing film 21A and the second sealing film 22A are the same two-layer film.

Each of the first sealing membrane 21A and the second sealing membrane 22A has a proximal edge extending to the inlet of the inflation valve 20A of the inflation unit 11A, and a distal edge extending to the inflation unit. internal. Preferably, borders of near and far edges of the first sealing film 21A and the second sealing film 22A adjoin each other.

In this embodiment, the near edge of the first sealing film 21A is bonded to the first air chamber layer 101A. The near edge of the second sealing film 22A is bonded to the second air chamber layer 102A.

The non-return sealing film 23A overlaps the proximal ends of the first sealing film 21A and the second sealing film 22A to form an air-filled gap between the first sealing film 21A and the non-return sealing film 23A. channel 24A, and a non-return channel 25A is formed between the non-return sealing film 23A and the second sealing film 22A.

The inflation channel 24A is arranged to fill the inflation chamber 12A with air to fill the inflation unit 11A until the air pressure in the inflation chamber 12A makes the first sealing film 21A and the second sealing membrane 21A The distal ends of the two sealing membranes 22A overlap and seal to close the inflation channel 24A. According to this preferred embodiment, when gas leaks from between the distal ends of the first sealing film 21A and the second sealing film 22A, the air in the inflatable cavity 12 is guided into the stop. back to the channel 25A to generate supplementary air pressure to further seal the inflation channel 24A to compensate for the lack of sealing effect of the first sealing film 21A and the second sealing film 22A.

The inflation channel 24A has two open ends, one of which is near the open end and is formed near the edge of the first sealing film 21A and the non-return sealing film 23A. The other distal open end extends to the distal edges of the first sealing film 21A and the second sealing film 22A, so as to communicate with the air-filled cavity 12A. Compressed air may be directed into the plenum chamber 12A through the plenum passage 24A.

It is worth mentioning that when the inflatable unit 11A is filled with air, the air pressure in the inflatable cavity 12A exerts pressure on the first sealing film 21A and the second sealing film 22A, thereby sealing the first sealing film. membrane 21A and the second sealing membrane 22A distal edge, and seals the distal open end of the inflation channel 24A. In addition, the distal ends of the first sealing film 21A and the second sealing film 22A are sealed together due to surface tension.

The non-return sealing film 23A is a thin flexible film made of plastic. Preferably, the non-return sealing film 23A, the first sealing film 21A and the second sealing film 22A are polyethylene (PE) films.

Similarly, in order to keep a space between the second sealing film 22A and the non-return sealing film 23A after the heat sealing process, the inflation valve 20A also includes a second heat-resistant material 27A, which Formed between the second sealing film 22A and the non-return sealing film 23A to ensure the formation of the non-return passage 25A.

Specifically, the second heat-resistant material 27A is disposed on the distal edge portions of the second sealing film 22A and the non-return sealing film 23A, so as to ensure that the distal end of the non-return channel 25A is in an open state. It is worth mentioning that the proximal end of the non-return channel 25A is closed by the second sealing joint 202 .

According to this preferred embodiment, the first heat-resistant material 26A and the second heat-resistant material 27A are two heat-resistant layers, which are coated on the predetermined positions on the respective corresponding films to prevent The media is glued together. The first heat-resistant object 26A extends on the proximal side of the non-return sealing film 23A and faces the first sealing film 21A. The second heat-resistant object 27A extends on the opposite side of the far end of the non-return sealing film 23A, and faces the second sealing film 22A, wherein the second heat-resistant object 27A is not arranged on the non-return sealing film 23A. The opposite side of the proximal end of the sealing membrane 23A is back sealed, so that the proximal end of the non-return channel 25A can be closed by the second sealing joint 202A. It is worth mentioning that the second heat-resistant material 27A not only prevents the non-return sealing film 23A from being bonded to the second sealing film 22A, but also ensures that the distal end of the non-return channel 25A is in the In an open state, the interaction between the non-return sealing film 23A and the first sealing film 21A is strengthened, thereby closing the inflation channel 24A due to surface tension.

The width of the inflation channel 24A is bounded by the lateral sealing joint 203A. Specifically, the two laterally sealed joints 203A are two inclined heat-sealing lines, so that the width of the inflation channel 24A gradually decreases from the opening of the air valve to each of the inflation chambers. In other words, the near open end of the inflation passage 24A is a larger open end which communicates with the valve opening, and the far open end of the inflation passage 24A is a tapered open end and connects with the air valve opening. The gas chamber 12A communicates. The tapered inflation channel 24A further prevents air from leaking from the inflation chamber 12A to the air valve opening.

Preferably, said lateral sealing joint 203A extends from the proximal edge to the distal edge of said first sealing membrane 21A and said second sealing membrane 22A. Therefore, the lateral sealing joint 203A is located at the proximal end portions of the first sealing membrane 21A and the second sealing membrane 22A and the non-return sealing membrane 23A is bonded together. The lateral sealing joint 203A is located at the distal end portions of the first sealing film 21A and the second sealing film 22A and is glued together with the first sealing film 21A and the second sealing film 22A.

Correspondingly, in order to inflate the inflatable unit 11A, the prong of the pump is inserted into the inflatable port 13A to inflate the compressed air into the inflatable channel 24A, wherein the inflation direction of the air is from the near open end of the inflatable channel 24A to the far open end. Thus the inflation unit 11A starts to inflate. The air pressure of the air-filled cavity 12A is increased to expand the first air chamber layer 101A and the second air chamber layer 102A. At the same time, the air pressure acts on the first sealing film 21A and the second sealing film 22A, especially on the distal ends of the first sealing film 21A and the second sealing film 22A. When the inflatable unit 11A is completely filled with air, that is, after reaching the maximum filling volume, the air pressure in the inflatable cavity 12A is sufficient to seal the distal ends of the first sealing film 21A and the second sealing film 22A, so that The distal open end of the inflation channel 24A is automatically sealed. At this moment, the prong of the pump is pulled away from the charging port 13A.

When the distal ends of the first sealing film 21A and the second sealing film 22A are not completely sealed together, the air in the inflation cavity 12A may leak into the inflation channel 24A. In order to avoid air leakage into the inflation channel 24A, the non-return sealing film 23A is sealed with the first sealing film 21A to seal the far open end of the inflation channel 24A. Specifically, the air intake direction of the non-return passage 25A is opposite to the inflation direction of the inflation passage 24A. In addition, when the open end of the non-return passage 25A is opened, the distal open end of the inflation passage 24A is closed. Therefore, air enters from the open end of the non-return passage 25A and remains in the non-return passage 25A.

The check passage 25A is filled with air such that supplemental air pressure is generated within the check passage 25A to further seal the inflation passage 24A. In particular, the distal open end of the inflation channel 24A between the first sealing membrane 21A and the non-return sealing membrane 23A is sealed. More specifically, the higher the supplementary air pressure in the non-return passage 25A, the better the sealing effect of the non-return sealing film 23A. In other words, when the air leaks from the inflatable chamber 12A to reduce the air pressure in the inflatable chamber 12A, the air enters the non-return passage 25A to increase the air pressure in the non-return passage 25A. Therefore, the total pressure of the inflation pressure, that is, the sum of the pressures of the inflation chamber 12A and the non-return passage 25A remains unchanged. In this way, the air entering the non-return passage 25A from the inflation chamber 12A will enter to strengthen the sealing effect of the inflation passage 24A.
