In this preferred embodiment of the present invention, the air-packing device may be implemented as an air cushion material, i.e., the air is filled with the air as an example. Of course, it will be appreciated by those skilled in the art that other gases are possible in the application as desired. In this preferred embodiment, it is inflated to form a three-dimensional package, thereby providing an air cushioning effect to the packaged product.

Specifically, in the preferred embodiment of the present invention, the air-packing device comprises at least one main air-packing buffering body 10, i.e. the main air-packing buffering body 10 forms a three-dimensional packing bag or a plurality of three-dimensional packing bags, and the main air-packing buffering body 10 is formed by plastic-sealing connection, such as bonding or heat-sealing. In the preferred embodiment of the present invention, the main inflatable cushion body 10 comprises at least two layers of gas chamber films 11 and 12 formed into the three-dimensional packaging bag including one or more connected gas storage units 13 through a series of planar plastic sealing seams and three-dimensional plastic sealing seams, each gas storage unit 13 is formed with a gas storage chamber 14 capable of storing gas therein.

In the above preferred embodiment, as shown in fig. 1A to fig. 1C, the structure of the inflation valve 20 of the present invention is schematically illustrated. Referring to fig. 1A, the main air-packing device 10 further includes an air-filling valve 20 formed of at least two valve films 21 and 22, the valve films 21 and 22 of the air-filling valve 20 and the gas cell films 11 and 12 are disposed to overlap each other, and an air-intake passage 23 for filling the air reservoir 14 is formed between the valve films 21 and 22. It will be appreciated that the valve membranes 21 and 22 are shorter in length than the gas chamber membranes 11 and 12. When the air reservoir 14 is filled with air through the air inlet passage 23 and the air pressure in the air reservoir 14 reaches a predetermined requirement, the air pressure in the air reservoir 14 acts on the valve films 21 and 22 to make the valve films 21 and 22 adhere to one of the air chamber films, thereby closing the air inlet passage 23 so that the air filling valve 20 functions as a one-way valve. When at least one air inlet channel 23 is formed in each air storage unit 13 and each air storage unit 13 is independent from each other, when one air storage unit 13 is damaged and air leakage occurs, the other air storage units 13 are not affected, and an air buffering effect can be achieved. As shown in FIG. 1B, the inflation valve 20 may further include the addition of a valve membrane 25 positioned between the two valve membranes 21 and 22 for enhanced sealing. As shown in fig. 1C, the inflation valve 20 may further include a valve membrane 26 between the gas chamber membrane 12 and the valve membrane 22, i.e., outside the two valve membranes 21 and 22, so as to prevent the joint of the valve membrane 22 and the gas chamber membrane 12 from being torn, thereby enhancing the stable joint thereof. It is to be understood that the specific structure of the inflation valve 20 is provided as an example and not as a limitation on the present invention.

It is to be understood that the gas chamber membranes 11 and 12 of the inflatable cushion body 10 and the valve membranes 21 and 22 of the inflation valve 20 can be made of various suitable film materials, such as polyethylene film, polypropylene film, polyvinyl chloride film, polyester film, polystyrene film or composite film, etc., and the present invention is not limited in this respect, as long as the film materials are suitable flexible films. It is worth mentioning that, in order to increase the one-way sealing effect, the valve films 21 and 22 of the inflation valve 20 may also be self-adhesive films obtained by modifying the above films by adding chemical components.

The main inflatable cushion 10 further includes a main channel unit connected to each of the air storage units 13, and preferably integrally extended from each of the air storage units 13. More specifically, in one embodiment, the main channel unit is perpendicular to the extending direction of the air storage unit 13. For example, in one embodiment, each of the air storage units 13 extends in a longitudinal direction, and the main channel unit extends in a transverse direction. The main passage unit forms a main passage 151, and the main passage 151 has an inflation port from which gas enters the main passage 151 in a lateral direction and then enters each of the gas storage units 13 in a longitudinal direction when an inflation nozzle is positioned and an inflation operation is performed, and the valve films 21 and 22 of the inflation valve 20 are attached to one of the gas chamber films 11 or 12 after a predetermined gas pressure is reached in each of the gas storage chambers 14, thereby achieving self-closure to prevent the re-permeation of the inflated gas into the main passage 151.

It is understood that the main passage unit may be formed of two layers of the gas chamber films 11 and 12, two layers of the valve films 21 and 22, or one of the gas chamber films 11 or 12 and one of the valve films 21 or 22.

The planar plastic seam and the three-dimensional plastic seam may be formed by joining the multilayer films together by means of an adhesive or heat-seal joint, preferably in this preferred embodiment both the planar plastic seam and the three-dimensional plastic seam may be formed by a heat-seal process.

More specifically, the planar plastic sealing slit includes a plurality of rows of separating slits, which separate the two layers of gas chamber membranes 11 and 12 into a plurality of gas storage units 13. That is, it is preferable that each row of the separation slits is formed through a heat-sealing process which heat-seals the two gas cell films 11 and 12, thereby forming one row of the separation slits between the adjacent two gas storage units 13. The separation seam may be a continuous heat-sealing line so that a plurality of the gas storage units 13 are independent of each other. Thus, when one of the gas storage units 13 is damaged and leaks gas, the other gas storage units 13 may not be affected. Of course, it should be mentioned that the gas storage units 13 may also be interconnected, so that only one inflation valve 20 is needed to inflate all the gas storage units 13 with gas. That is, the air-packing device of the present invention can form a plurality of the gas storage units 13 by heat-sealing the first gas chamber layer 11 and the second gas chamber layer 12.

It is understood that the separation seams may be intermittent heat-sealing lines so that a plurality of the gas storage units 13 communicate with each other. The gas storage unit 13 may have various shapes, such as a bar shape, a circular shape, a polygonal shape, or other irregular shapes. The main inflatable buffer body 10 of the utility model can comprise a plurality of inflatable columns arranged side by side and having the same size, the main inflatable buffer body 10 can also comprise a plurality of inflatable columns arranged side by side and having different sizes.

It is to be understood that the side sealing seams 32 are formed by a plastic molding process such as bonding or heat-sealing and hermetically connect the two gas chamber films 11 and 12, and the main channel sealing seams 33 are formed by a plastic molding process such as bonding or heat-sealing and connect the two gas chamber films 11 and 12 and the two valve films 21 and 22, respectively, as shown in fig. 1A to 1C, and the main channel sealing seams 33 formed at the upper and lower sides, for example, by one heat-sealing process, respectively heat-seal the gas chamber film 11 and the valve film 21 at positions corresponding to the gas inlet channel 23, and heat-seal the gas chamber film 12 and the valve film 22 at other positions to integrally heat-seal the multi-layered films and divide the main inflatable cushion body 10 into the main channel unit and the gas storage unit 13.

As shown in fig. 1A to 1C, the valve films 21 and 22 are further heat-sealed to the gas chamber film 11 at a position adjacent to the main passage of each gas storage unit 13 through a plurality of connecting seams 35, so that when a predetermined gas pressure is reached in the gas storage chamber 14, the gas pressure acts on the valve films 21 and 22 and is simultaneously pressed toward the gas chamber film 11 and finally attached to the gas chamber film 11 due to the provision of the connecting seams 35, thereby closing the gas inlet passage 23. That is, the joining seam 35 heat-seals two layers of the valve films 21 and 22 and one layer of the gas chamber film 11. In addition, as shown in fig. 1A to 1C, the shape of each of the connecting seams 35 is designed such that it further functions to prevent gas from being returned, that is, when the gas in the gas storage chamber 14 is desired to be returned, it is blocked by the connecting seam 35 and cannot easily permeate back into the main passage 151. In addition, in the heat-sealing for forming these planar plastic seams, the air intake passages 23 of the valve films 21 and 22 of the inflation valve 20 may be formed by providing heat-resistant blocking means, which is removed after the heat-sealing process. In one embodiment, a heat-resistant layer 24, such as heat-resistant ink, is disposed between the valve films 21 and 22 of the inflation valve 20, as shown in fig. 1A to 1C, and is communicated with the main passage 151 without closing its inlet by heat-sealing. In one embodiment, the primary channel 151 is formed by two layers of the gas cell membranes 11 and 12, the heat-resistant layer 24 and the valve films 21 and 22 each have an extension into the main passage 151, the planar plastic seam further comprises a row of spaced apart longitudinally aligned welds 36 corresponding to the location of the extended length of the heat resistant layer 24, because of the provision of the heat-resistant layer 24, the joint seam 36 connects the two gas chamber membranes 11 and 12 and the two valve membranes 21 and 22 together, while the two valve membranes 21 and 22 are not heat sealed, the seam 36 is positioned such that when the border inflatable cushion body 10 is inflated, after gas, for example, gas, enters the main passage 151, the adjacent valve membranes 21 and 22 and the corresponding connected gas chamber membranes 11 and 12 can expand together to open the corresponding intake passage 23.

The plane plastic sealing seam further comprises a plurality of rows of bending seams which are in discontinuous heat sealing, and the inflated main inflatable buffer body 10 is suitable for bending along the bending seams, so that the main inflatable buffer body 10 forms three side walls. More specifically, the bending seams divide each of the air storage units into a plurality of sub air storage units. The bending seam may be located at the middle of the air storage unit 13, and communication channels are formed at both sides thereof, so that the adjacent sub air storage units are communicated with each other. It is understood that the bending slits may be located at both sides of the air storage unit 13, and the communication channel is located at the middle of the air storage unit 13. Accordingly, it will be appreciated that each column of the crease heat seals connects two layers of the gas cell membranes 11 and 12.
