Referring to fig. 1A to 3, there is shown a mask type air-packing device according to a preferred embodiment of the present invention. It has an inflatable body structure, and the medium for providing the cushioning effect is a fluid, such as gas, liquid, etc. In this preferred embodiment of the present invention, the hood-type air-packing device may be implemented as an air-cushion material, i.e., the inflated gas is exemplified by air. 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 can be formed into an inflatable bag having a mouthpiece-type structure when inflated, and having a circular receiving cavity when inflated, thereby providing an air cushioning effect to the round ball-packed item.

Specifically, in the above preferred embodiment, the mouth-cap type air-packing device includes at least one air-packing cushion body, that is, a three-dimensional packing bag is formed by one air-packing cushion body or a plurality of air-packing cushion bodies are connected by plastic sealing such as bonding or heat-sealing to form the three-dimensional packing bag.

More specifically, as shown in fig. 2, the planar plastic sealing slit 30 includes a plurality of rows of separation slits that separate two

gas chamber films

11 and 12 into a plurality of the 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 mouth-cap type air-packing device of the present invention can form a plurality of the air storage units 13 by heat-sealing the first gas chamber layer 11 and the second gas chamber layer 12.

It will be appreciated that the left and right rows of the separation slits may be left and right side boundary slits of the inflatable cushion body, respectively, as shown in fig. 2. It is worth mentioning that the left and right sides herein are relative concepts, which are defined according to the relative positions of the hood-type air-packing device with respect to the horizontal line. That is, the separation slits of the hood-type air-packing devices are defined as the left and right sides when they are relatively perpendicular to the horizontal line, but are defined as the top and bottom sides when they are relatively parallel to the horizontal line. The separation seam may also be an intermittent heat-sealing line 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 inflatable buffer body can comprise a plurality of inflatable columns which are arranged side by side and have the same size, and the inflatable buffer body can also comprise a plurality of inflatable columns which are arranged side by side and have different sizes. In addition, the arrangement of the large and small air columns may be varied, for example, they may be arranged alternately, small air columns may be formed in some areas, and the utility model is not limited in this respect.

In this preferred embodiment of the present invention, as shown in fig. 1A to 1C, the structure of the inflation valve 20 of the present invention is schematically illustrated. Referring to fig. 1A, the air-packing device further comprises 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 chamber films

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 will be appreciated that the specific configuration of the inflation valve 20 described above is by way of example only and is not limiting to the utility model.

It is to be understood that the

gas chamber membranes

11 and 12 of the inflatable cushion body and the

valve membranes

21 and 22 of the inflation valve 20, respectively, 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 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.

As shown in fig. 2, the inflatable cushion further includes a main channel unit 15 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 15 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 15 extends in a transverse direction. The main passage unit 15 forms a main passage 151, and the main passage 151 has an inflation port 152, when an inflation nozzle is provided at a position of the inflation port 152 and an inflation operation is performed, gas enters the main passage 151 from the inflation port 152 in a lateral direction and enters each of the gas storage units 13 in a longitudinal direction, and when a predetermined gas pressure is reached in each of the gas storage chambers 14, the

valve films

21 and 22 of the inflation valve 20 are adhered to one of the

gas chamber films

11 or 12, thereby achieving self-closure to prevent the re-permeation of the inflated gas into the main passage 151.

It is to be understood that the main passage unit 15 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 seam 30 further comprises a continuously sealed edge seal 32 on each of the top and bottom sides of the inflatable cushion body and a continuously sealed top-side main channel seal 33, wherein the top-side edge seal 32 and the main channel seal 33 form the main channel 151 therebetween. 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 inflation buffer body into the main channel unit 15 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 30, the air intake passages 23 of the

valve films

21 and 22 of the inflation valve 20 may be formed by providing heat-resistant barriers which are 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 in communication with the main passage 151 without closing its inlet by heat sealing. In one embodiment, the main passage 151 is formed by two layers of the

gas chamber films

11 and 12, the heat-resistant layer 24 and the

valve films

21 and 22 each have an extension into the main passage 151, and the planar plastic sealing seam 30 further includes a row of mutually spaced and longitudinally arranged joint seams 36 corresponding to the position of the extension of the heat-resistant layer 24. due to the arrangement of the heat-resistant layer 24, the joint seams 36 connect the two layers of the

gas chamber films

11 and 12 and the two layers of the

valve films

21 and 22, respectively, while the two layers of the

valve films

21 and 22 are not heat-sealed, and the arrangement of the joint seams 36 is such that, when the inflatable cushion body is inflated, after gas such as gas enters the main passage 151, the

adjacent valve films

21 and 22 and the correspondingly connected

gas chamber films

11 and 12 can be expanded together to open the corresponding gas inlet passage 23.

It will be understood by those skilled in the art that the planar plastic-sealing seam 30 is used for plastic-sealing the multi-layer film to form a planar cushion material as shown in fig. 2, and the three-dimensional plastic-sealing seam 40 is used for further plastic-sealing the planar cushion material to form a three-dimensional packaging device of the mouth-cover type air-filled packaging device, which has an ellipsoidal spatial three-dimensional configuration and can accommodate a packaged object of a circular sphere, and the three-dimensional packaging device can be formed into an ellipsoidal or circular sphere with different radians, etc. Preferably, in this preferred embodiment, both the planar plastic seam 30 and the three-dimensional plastic seam 40 may be implemented as being formed by a heat sealing process.

As shown in fig. 2 and fig. 3, the three-dimensional plastic sealing seam 40 includes a three-dimensional plastic sealing seam 49 of mask forming, the planar buffer material shown in fig. 2 is formed and then folded and heat-sealed along the three-dimensional plastic sealing seam 49 of mask forming, after the inflation valve 20 is used for inflating each air storage unit 13, because the folded and heat-sealed part of the three-dimensional plastic sealing seam 49 of mask forming keeps the adhesion state, and each air storage unit 13 in the middle inflates air to make the inflatable buffer body fully open from the middle, thereby finally forming an ellipsoid shape for packaging round or round-like objects, and further fitting the structure of the packaged object, and achieving a good buffering effect.

Due to the folding and heat sealing of the mask-forming three-dimensional plastic sealing seam 49, each gas storage unit 13 is inflated to form a gas column with uneven size, the two ends of which are less inflated and the middle of which is more inflated, wherein the parts of the small gas columns 131, the two ends of which are less inflated, in each gas storage unit 13 form two-end buffer parts, and the middle large gas column 132 forms a circular sphere conjunction part. After the gas storage units 13 are subjected to planar plastic packaging and three-dimensional plastic packaging, an ellipsoidal packaging space is formed, wherein the small gas columns 131 form end-side buffer parts of the mask type gas-filled packaging device of the utility model to provide a buffer effect for two ends of a packaged round ball, and the large gas columns 132 form round ball fitting parts of the mask type gas-filled packaging device of the utility model to fit the packaged round ball to limit the packaged round ball. It can be understood that the opening end part left after the final forming is smaller, the packaged round ball body can not be separated from the inside of the fitting part of the round ball body, and it is worth mentioning that because the opening end part left after the final forming is smaller, each gas storage unit 13 at the opening can also form a buffer side wing, so that the buffer effect is further enhanced.
