Referring to fig. 1 to 3, there is shown an air-packing device for an elongated tubular article according to a preferred embodiment of the present invention, which has an inflatable structure, and a medium for providing a cushioning effect is a fluid, such as gas, liquid, etc. In this preferred embodiment of the present invention, the air-packing device for elongated tubular articles may be embodied as an air-cushioning material, i.e., the air is filled with 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 possible to form an inflatable bag when inflated, which has a combined structure provided with inflated and uninflated air, to enhance the cushioning effect on the elongated tubular article.

Specifically, in the above preferred embodiment, the air-packing device for elongated tubular articles comprises at least one air-packing cushion body 10, i.e. a three-dimensional packing bag is formed by one air-packing cushion body 10 or a plurality of air-packing cushion bodies 10 are connected by plastic sealing, such as bonding or heat sealing, to form the three-dimensional packing bag. In the example of the present invention shown in fig. 1A to 5, it is formed by one of the inflatable cushion bodies 10. More specifically, the inflatable cushion body 10 includes at least two layers of gas chamber films 11 and 12, which are formed into the three-dimensional packaging bag including one or more connected gas storage units 13 through a series of plane plastic sealing seams and three-dimensional plastic sealing seams, and each gas storage unit 13 is formed with a gas storage chamber 14 capable of storing gas therein.

As will be understood by those skilled in the art, the planar plastic sealing seam is used for plastic sealing the multilayer film to form a planar cushion material as shown in fig. 2 and 3, and the three-dimensional plastic sealing seam is used for further plastic sealing the planar cushion material to form the air-filled packing device for the elongated tubular article into a spatial three-dimensional configuration and to accommodate the elongated tubular article. 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, as shown in fig. 2 and 3, the planar plastic sealing slit includes a plurality of rows of separation slits, which separate two layers of gas chamber films 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 is worth mentioning that the gas storage units 13 may also be interconnected, so that only one inflation valve is needed to inflate all the gas storage units 13 with gas. That is, the air-packing device for elongated tubular articles of the present invention can form a plurality of the air storage cells 13 by heat-sealing the first gas chamber layer 11 and the second gas chamber layer 12.

In this preferred embodiment of the present invention, as shown in fig. 1A to 1C, the structure of the inflation valve of the present invention is schematically illustrated. Referring to fig. 1A, the air-packing device further comprises an air-packing valve formed of at least two valve films 21 and 22, the valve films 21 and 22 of the air-packing valve are disposed to overlap the gas cell films 11 and 12, and an air-intake passage 23 for inflating the gas 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 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 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 may further include a valve film 26 between one of the gas chamber films 12 and 22, i.e., outside of the two valve films 21 and 22, thereby serving to prevent the joint of the valve film 22 and the gas chamber film 12 from being torn, and to reinforce the stable joint thereof. It will be understood that the specific structure of the inflation valve described above is by way of example only and is not limiting of the utility model.

It is to be understood that the gas chamber films 11 and 12 of the inflatable cushion body 10 and the valve films 21 and 22 of the inflation valve may 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 it is a suitable flexible film. It is worth mentioning that, in order to increase the one-way sealing effect, the valve membranes 21 and 22 of the inflation valve may also be self-adhesive films obtained by modifying the above films by adding chemical components.

As shown in fig. 2, the inflatable cushion body 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 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.

As shown in fig. 2, the planar plastic sealing seam further includes a continuously sealed side sealing seam 32 and a continuously sealed main channel sealing seam 33 on the inflation valve side, respectively, at the side of the inflatable cushion body 10, wherein the main channel 151 is formed between the side sealing seam 32 on the inflation valve side and the main channel sealing seam 33. 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 of both sides, which are formed by, for example, 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, and other positions integrally heat-seal the multi-layered films and divide the 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 through a plurality of connecting seams 35 at a position adjacent to the main channel 151 of each gas storage unit 13, 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 channel 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 heat-sealing these planar plastic seams, the air intake passages 23 of the valve films 21 and 22 of the inflation valve 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, as shown in fig. 1A to 1C, and is in communication 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 films 21 and 22 are not heat-sealed, the seam 36 is arranged so that when the 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.
