Background

In recent years, with the rapid development of the e-commerce industry, people's lives and shopping modes are greatly changed, and more people choose an online shopping mode to shop. The online shopping can greatly facilitate the life of people, when people need to buy commodities, the people only need to select and buy the commodities on the network and pay corresponding expenses, and then the commodities selected and bought by the people can be received through express delivery in a short time, so that the people can select and buy the commodities around the world without going out of the house, and great convenience is brought to the life of the people.

The wide use of online shopping also drives the development of the express transportation industry to a certain extent, and commodities purchased on the internet by people can be transported to the hands of sellers by merchants in an express transportation mode.

After the purchased commodities are sent out by a merchant in an express transportation mode, long-time and long-distance transportation is often carried out, and the commodities can be transported to the hands of purchasers only by carrying out multiple times of transportation in the transportation process. Therefore, the purchased goods are very easy to be damaged in the express transportation process, especially when the goods to be transported are fragile goods, such as fruits, vegetables, precision electronic products and the like, and are very easy to be damaged in the express transportation process.

In order to prevent the goods from being damaged in the process of express transportation or reduce the damage degree of the goods in the process of transportation, people often add a layer of buffer material between the goods to be transported and the transportation box body so as to reduce the collision between the goods to be transported and the box body. At present, the cushioning materials widely used are foam boards and corrugated paper, and because the foam boards and the corrugated paper are solid, the cushioning effect is limited, and the solid foam boards and the solid corrugated paper can occupy larger transportation and storage space when being transported and stored, so that the transportation and storage cost is increased. Most importantly, the use of foam boards in large quantities causes huge environmental pollution.

At present, a gas buffering packaging material is also available in the market, and the gas buffering packaging material adopts gas as a buffering material, so that the gas buffering packaging material not only has a good buffering effect, but also has the advantages of light weight and the like. Most importantly, the gas cushioning packaging material has a relatively small volume when not inflated, facilitating storage and transport. Can be inflated quickly when in use, and has the function of buffering protection.

Referring to fig. 1, there is provided an air-packing device (application No. 02828176.4, entitled structure for mounting an opening/closing valve of a sealed body and device for manufacturing a sealed body with an opening/closing valve) disclosed in the prior art, wherein an opening/closing valve 2 is mounted on a sealed body 1 which is made of soft resin sheets (1a, 1b) and can fill air into the sealed body, and the opening/closing valve 2 is bonded to one sheet 1a of the sealed body 1 by a fixing seal portion and the other sheet 1b is not bonded by the fixing seal portion, as shown in the figure. In this way, even when air is filled in the expansion portion 12 of the seal body 1, the opening/closing valve 2 is always in close contact with the one piece 1a, so that no wrinkle occurs in the opening/closing valve 2, and air does not leak through the wrinkle.

As shown in the drawing, in the prior art, the air introduction passage 11 is provided at one end of the seal body so as to penetrate in the left-right direction and is provided perpendicular to each of the opening and closing valves 2, so that the gas in the air introduction passage can pass from left to right to each of the opening and closing valves, thereby inflating the expansion portion 12. Therefore, when the inflation portion 12 is inflated by the introduction passage 11 and the opening/closing valves 2, the gas first enters the introduction passage 11, then sequentially enters the opening/closing valves 2 communicating with the introduction passage 11, and finally enters the inflation portions 12.

In order to improve the inflation efficiency and realize the industrial production of the air packing bags, the prior art air packing bags are inflated by directly aligning an inflator with an air introducing passage of the air packing bag so as to apply inflation pressure to the air packing bag.

In the conventional technique shown in fig. 1, the air introduction path 11 is formed by heat sealing, and the firmness depends on the thickness and heat resistance of the two bag sheets 1a and 1b made of soft resin sheets forming the air introduction path 11, so that if the inflation pressure of the inflator entering the air introduction path 11 is too high after the heat sealing, the two bag sheets 1a and 1b made of soft resin sheets forming the air introduction path 11 are easily pressed, and therefore, a crack is easily generated at the heat sealing position, that is, the sealing position of the air introduction path 11, to break the air introduction path 11, thereby damaging the air packaging bag.

In detail, as shown in fig. 1 to 13, in the first embodiment of the present invention, the air-packing device 10 includes one or more air cushion bodies 11, and any one of the air cushion bodies 11 is formed by heat-sealing two or more layers of flexible films through a series of heat-sealing lines to form an air-storable air cushion material.

Any of the air cushion bodies 11 includes an air storage unit 111 formed by at least two air cell films 13 through a heat sealing process, and having at least one air inlet 1110. The two air chamber films are separated by a plurality of rows of separation seams 121 to form a plurality of air storage units 111, that is, each row of separation seams 121 is formed by a heat sealing process, and the two air chamber films are heat-sealed and connected, so that one row of separation seams 121 is formed between two adjacent air storage units 111. The gas storage unit 111 may be implemented in any shape, including but not limited to a bar shape, a circle shape, a polygon shape, or other regular or irregular shapes.

The air cushion 11 further includes an inflation channel 112 communicating with each of the air storage units 111 through the air inlet 1110 of each of the air storage units 111. preferably, in the first embodiment of the air-packing device 10 of the present invention, the two layers of air cell films respectively include an air cell film main body portion 131 and an inflation end portion 132 integrally extending from the air cell film main body portion 131, wherein the air cell film main body portion 131 is used to form the air storage unit 111 through a heat-sealing process, and a portion of the air cell film adjacent to the inflation side forms the inflation end portion 132 of the inflation channel 112. The two air cell films are heat-sealed together by heat-sealing the edges of the two air cell films, which are joined to each other by the edge heat-seal seam 122, which is formed by a heat-sealing process of heat-sealing the edges of the two air cell films, which are joined to each other at their distal edges 132.

The air buffer material further has an inflation channel opening 1320, and the inflation channel opening 1320 connects the inflation channel 112 and the external environment, so that the external air can enter the inflation channel 112 through the inflation channel opening 1320 and enter the air storage unit 111 through the inflation channel 112 and the air inlet 1110.

In the first embodiment of the air-packing device 10 of the present invention, the inflation channel opening 1320 is formed at one end of the inflation channel 112, i.e. one end of the inflation channel 112 is not heat sealed by a series of heat sealing lines, so that the inflation channel 112 can be inflated by inflation gas to inflate the air storage unit 111, and the air-packing device 10 provides an air cushion effect.

The air-packing device 10 further includes at least one air-packing channel heat-seal line 133 and the air-packing channel 112 is formed by heat-sealing the air-packing channel heat-seal line 133. The air-filling channel heat-sealing line 133 is formed at one end of the two layers of air chamber films by heat-sealing, and both ends of the air-filling channel heat-sealing line 133 are respectively connected with both ends of the outside of the air-packing device 10 formed by one or more air buffer bodies 11 and the separation seams 121 of the air storage units 111 at both ends of the outermost side by heat-sealing, so as to form the air-filling channel 112.

The inflation channel 112 and the gas storage unit 111 are respectively formed at the upper and lower ends of the inflation channel heat-seal line 133, the inflation channel 112 is located between the inflation channel heat-seal line 133 and the edge heat-seal seam 122, the gas storage unit 111 is located at the lower portion of the inflation channel heat-seal line 133, and the inflation channel 112 is communicated with each gas storage unit 111 through the corresponding gas inlet 1110.

As a variation of the first embodiment of the air-packing device 10 of the present invention, two layers of the air cell film may also be formed by folding the entire film in half along a folding line, i.e., two layers of the air cell film integrally extends, wherein the inflation channel 112 correspondingly also includes two inflation ends 132 integrally connected after being folded in half, so that the inflation channel 112 is formed between the folding line and the air inlet 1110 without the edge heat-seal seams 122 of the first embodiment.

Furthermore, any one of the air buffers 11 includes a one-way inflation valve 14 for one-way inflation, and the one-way inflation valve 14 is disposed between the air storage unit 111 and the inflation channel 112, so that the one-way inflation valve 14 communicates the inflation channel 112 and all the air storage units 111, and prevents the inflation gas in the air storage units 111 from returning to the inflation channel 112, so that the gas can be retained in the air storage units 111, and the air buffer 11 and the air-packing device 10 formed by the air buffer 11 have the function of buffering protection.

As shown in the drawings, the one-way inflation valve 14 of the first embodiment of the inflation device of the present invention is schematically shown in the cross-sectional views A-A and B-B. The one-way inflation valve 14 includes a first valve film 141 and a second valve film 142, and the first valve film 141 and the second valve film 142 are stacked corresponding to each other and disposed between the two air cell films.

Since the one-way inflation valve 14 has the gas inlet 1110, the gas inlet 1110 communicates the inflation channel 112 and the gas storage unit 111, and the gas in the inflation channel 112 can enter the gas storage unit 111 through the gas inlet 1110.

The one-way inflation valve 14 further comprises a heat-resistant layer 143, wherein the heat-resistant layer 143 is disposed between the first valve film 141 and the second valve film 142 of the one-way inflation valve 14, so that when the first valve film 141 and the second valve film 142 of the one-way inflation valve 14 are respectively heat-sealed to the two air cell films, the air inlet 1110 is not blocked by the heat-sealing between the first valve film 141 and the second valve film 142.

It is emphasized that in the first embodiment of the air-packing device 10 of the present invention, the heat-resistant layer 143 of the one-way air-packing valve 14 is printed with heat-resistant ink. Preferably, the heat-resistant layer 143 is printed with heat-resistant varnish, and since varnish itself has a transparent characteristic, the heat-resistant layer 143 can be made transparent after printing, and thus the entire air-packing device 10 is transparent. Thereby enabling the overall feeling of the air-packing device 10 to be further improved.

In detail, the two air cell films are a first air cell film 1301 and a second air cell film 1302 respectively, when the air inflation channel heat sealing line 133 is formed by heat sealing, the first valve film 141 and the second valve film 142 are located between the first air cell film 1301 and the second air cell film 1302, and when the air inflation channel heat sealing line 133 heat seals the first air cell film 1301, the second air cell film 1302, the first valve film 141 and the second valve film 142, the air inlet 1110 between the first valve film 141 and the second valve film 142 is kept in a communication state due to the existence of the heat-resistant layer 143.

That is, the heat-resistant layer 143 is provided between the first valve film 141 and the second valve film 142, and when the air inflation channel heat-seal line 133 is formed by heat-sealing, the first valve film 141 can be heat-sealed to the first air cell film 1301, the second valve film 142 can be heat-sealed to the second air cell film 1302, but the first valve film 141 and the second valve film 142 are not heat-sealed, and the air inlet 1110 is formed between the first valve film 141 and the second valve film 142.

At the position where the heat-resistant layer 143 is provided between the first valve film 141 and the second valve film 142, the first air cell film 1301, the first valve film 141, the second valve film 142, and the second air cell film 1302 are heat-sealed to each other at the time of forming the inflation channel heat-seal line 133. The upper ends of the first valve film 141 and the second valve film 142 of the one-way inflation valve 14 are positioned in the inflation channel 112, the lower ends of the first valve film 141 and the second valve film 142 are positioned in the air storage unit 111, and the lower ends of the first valve film 141 and the second valve film 142 are heat-sealed and fixed to the first air chamber film 1301.

It should be noted that, when the inflation channel heat-seal line 133 is formed by heat-sealing, the first valve film 141 and the second valve film 142 are located between the first air cell film 1301 and the second air cell film 1302, and the inflation channel heat-seal line 133 heat-seals and connects the first air cell film 1301, the second air cell film 1302, the second valve film 142, and the second air cell film 1302. Since the heat-resistant layer 143 is provided between the first valve film 141 and the second valve film 142, the position of the heat-resistant layer 143 between the first valve film 141 and the second valve film 142 is not heat-sealed when the first air cell film 1301, the second air cell film 1302, the first valve film 141, and the second valve film 142 are heat-sealed at the same time by the inflation channel heat-sealing line 133, thereby forming the intake port 1110.

When the air-packing device 10 is inflated, the inflation gas first enters the inflation channel 112 and then enters the corresponding respective air container units 111 through the gas inlet 1110 communicating with the inflation channel 112 and the respective air container units 111, and when the gas content in the air container units 111 reaches a certain level, the first valve film 141 and the second valve film 142 are tightly pressed toward the first air cell film 1301 under the gas pressure of the air container units 111, thereby closing the gas inlet 1110 formed between the first valve film 141 and the second valve film 142 to prevent the gas entering the air container units 111 from leaking again through the gas inlet 1110 and the inflation channel 112.

Packaging hardware 10 further include an at least additional strengthening 15 the first embodiment of air-packing device 10, additional strengthening 15 is implemented as a reinforced plastic package line 151, reinforced plastic package line 151 set up in inflation channel 112 is located on heat-resistant layer 143, thereby makes gas in inflation channel 112 can pass through reinforced plastic package line 151 gets into air inlet 1110, and then gets into gas storage unit 111, so that gas storage unit 111 can provide the effect of air buffering.

In detail, as shown in the drawings, in the first embodiment of the air-packing device 10 of the present invention, the reinforced plastic sealing line 151 is disposed in the air filling channel 112, and the direction of the air filling channel 112 is the same, and the reinforced plastic sealing line 151 is disposed on the heat-resistant layer 143, the reinforced plastic sealing line 151 and one or more buffer channels are formed between the heat-resistant layers 143, that is, the reinforced plastic sealing line 151 does not completely heat-seal the air filling channel 112, and the inflation gas can still pass through the buffer channels and follow the air filling channel 112 on the heat-resistant layer 143 to enter the air storage unit 111.

It should be noted that in the air-packing device 10 of the present invention, the two ends of the reinforced plastic-sealed line 151 are respectively heat-sealed with the two ends of the air-filled channel heat-sealed line 133, through the combination of the reinforced plastic-sealed line 151 with the air-filled channel 112, so that the air-filled channel 112 forms an air-intake region 1121 and a buffer region 1122, and the air-filled gas can only pass through the air-filled channel opening 1320 to inflate the air-packing device 10.

When the external inflation gas fills the inflation channel 112 through the inflation channel opening 1320, the gas firstly enters the air intake region 1121 of the inflation channel 112, the inflation gas in the air intake region 1121 will respectively enter the buffer region 1122 through one or more buffer channels, and then respectively enter the gas storage unit 111 through the corresponding gas inlets 1110.

When the air-packing device 10 is inflated by the inflating device, if the air inlet pressure of the inflating device is too large, the air inlet region 1121 is pressed too large and the air inlet pressure passes through the buffer channel, at this time, because the reinforced plastic sealing line 151 is a discontinuous heat sealing line, the air pressure in the air inlet region 1121 firstly breaks through the reinforced plastic sealing line 151, i.e., the air inlet region 1121 and the buffer region 1122 are partially or completely communicated, at this time, the inflating gas with the released pressure can respectively enter the corresponding air storage unit 111 through the air inlet 1110, so that the air-packing device 10 of the present invention can provide an air buffering effect.

Preferably, in the first embodiment of the air-packing device 10 of the present invention, the reinforcing plastic sealing line 151 is provided at the upper end of the heat-resistant layer 143, and the top ends of the first valve film 141 and the second valve film 142 are heat-sealed to the first air cell film 1301 and the second air cell film 1302 through the reinforcing plastic sealing line 151.

In other words, in the first embodiment of the air-packing device 10 of the present invention, the top ends of the first valve film 141 and the second valve film 142 are heat-sealed and fixed by the reinforcing plastic sealing wire 151, so that the air-intake region 1121 of the inflation channel 112 is formed by the first air cell film 1301 and the second air cell film 1302, and the buffer region 1122 of the inflation channel 112 includes the first air cell film 1301, the second air cell film 1302, the first valve film 141 and the second valve film 142, thereby reducing the resistance of the inflation gas entering the buffer channel at the air-intake region 1121 while not affecting the entry of the inflation gas into the buffer region 1122 through the buffer channel, and further improving the inflation efficiency of the air-packing device 10.

Further, heat-sealing the top ends of the first and second valve films 141 and 142 to the first and second air cell films 1301 and 1302 by the reinforcing plastic sealing lines 151 not only improves the inflation efficiency of the air-packing device 10 but also aligns the positions of the first and second valve films 141 and 142 with respect to the first and second air cell films 1301 and 1302.

In other words, in the first embodiment of the air-packing device 10 of the present invention, the reinforced plastic sealing lines 151 can not only divide the air inflation passage 112 into the air intake region 1121 and the buffer region 1122, thereby reducing the risk of the air-filling duct 112 being damaged by rapid air-filling, while also enabling the calibration of the relative positions of the first valve film 141, the second valve film 142, the first air cell film 1301 and the second air cell film 1302 during the production of the air-packing device 10, thereby avoiding calibration of the relative positions of the first valve film 141, the second valve film 142, the first plenum film 1301 and the second plenum film 1302 by other processes or process steps, therefore, the air-packing device 10 of the present invention can also improve the production efficiency and save the production cost.

As a variation of the first embodiment of the present invention, a person skilled in the art may dispose the top ends of the first valve film 141 and the second valve film 142 in the air inlet region 1121 or even be fixed by the edge heat-sealing seam 122. As long as on the above-mentioned technical scheme's that exposes basis of the utility model, adopted with the utility model discloses the same or similar technical scheme, solved with the utility model discloses the same or similar technical problem to reached with the utility model discloses the same or similar technological effect all belongs to within the protection scope, the utility model discloses a concrete implementation does not use this as the limit.

Figure 5 is a schematic cross-sectional view of a variant embodiment of the one-way inflation valve 14 'in the first embodiment of the air-packing device 10' of the present invention shown in figure a-a. In this alternative embodiment, the one-way inflation valve 14 ' further includes a check film 144 ', the check film 144 ' being disposed between the first and second valve films 141 ', 142 '. An upper end portion of the check film 144 'is heat-sealed to an upper end portion of the second valve film 142', a lower end portion of the check film 144 'is located between the lower end portions of the first and second valve films 141' and 142 ', and a length of the check film 144' is smaller than those of the first and second valve films 141 'and 142'.

The gas inlet 1110 'is formed between the first valve film 141' and the check film 144 ', and the gas in the inflation channel 112' is allowed to enter the gas storage unit 111 'through the gas inlet 1110' by the gas inlet region 1121 'and the buffer region 1122' formed by the reinforcing plastic sealing wires 151 'in the reinforcing structure 15', respectively. When the gas content in the gas container unit 111 'reaches a certain amount, the lower end portions of the first valve film 141', the second valve film 142 ', and the check film 144' are tightly pressed toward the first air chamber film 1301 'by the gas pressure in the gas container unit 111', thereby closing the gas inlet 1110 'formed between the first valve film 141' and the check film 144 'to prevent the gas in the gas container unit 111' from leaking again through the gas inlet 1110 'and the inflation channel 112'.

In the present modified embodiment, when gas inside the gas storage unit 111 ' leaks between the first valve film 141 ' and the second valve film 142 ', the gas cannot be leaked to the outside through between the check film 144 ' and the second valve film 142 ' because the upper end portion of the check film 144 ' is heat-sealed to the upper end portion of the second valve film 142 ', when the gas leaks between the check film 144 ' and the second valve film 142 '.

When the amount of gas leaked between the check film 144 'and the second valve film 142' reaches a certain degree, the check film 144 'is tightly pressed against the first valve film 141' by the gas pressure between the check film 144 'and the second valve film 142', thereby further sealing the gas inlet 1110 'to allow the gas storage unit 111' to achieve an effect of not leaking gas entirely even if partially leaked gas.

As shown in FIG. 6, another modified embodiment of the one-way inflation valve 14 "in the first embodiment of the air-packing device 10" of the present invention is shown in a schematic sectional view taken along the line A-A.

In this modified embodiment, the one-way inflation valve 14 "further includes a reinforcing film 145", the reinforcing film 145 "is disposed between the second valve film 142" and the second air cell film 1302 ", and an upper end portion of the reinforcing film 145" is heat-sealed and connected between an upper end portion of the second valve film 142 "and the second air cell film 1302", and a lower end portion of the reinforcing film 145 "is movably located between a lower end portion of the second valve film 142" and the second air cell film 1302 ".

The gas in the inflation channel 112 "is allowed to enter the gas storage unit 111" through the gas inlet 1110 "via the gas inlet region 1121" and the buffer region 1122 "formed by the reinforced plastic sealing lines 151" in the reinforcing structure 15 ", respectively. When the content of the gas filled in the gas storage unit 111 "reaches a certain level, the lower end portions of the first valve film 141", the second valve film 142 ", and the reinforcing film 145" are tightly pressed against the first air chamber film 1301 "by the gas pressure in the gas storage unit 111", thereby sealing the gas inlet 1110 "between the first valve film 141" and the second valve film 142 "and preventing the gas entering the gas storage unit 111" from leaking. The reinforcing membrane 145 "is located outside the second valve membrane 142", and the reinforcing membrane 145 "is directly in contact with the gas inside the gas storage unit 111", thereby functioning to protect the second valve membrane 142 "and enhance the sealing effect.

Further, the air-packing device 10 of the present invention further comprises at least one heat-sealing unit 16, wherein the heat-sealing unit 16 partially heat-seals the first valve film 141 and the second valve film 142 located in the air container unit 111 to the first air cell film 1301 or the second air cell film 1302.

In detail, as shown in the drawings, in the first embodiment of the air-packing device 10 of the present invention, the heat-sealing unit 16 is smiling-face-shaped, and includes two symmetrically disposed heat-sealing strips 161 and two heat-sealing points 162 disposed below the two heat-sealing strips 161, wherein the two heat-sealing strips 161 and the two heat-sealing points 162 are symmetrically disposed in the air storage unit 111, so that the air can be uniformly introduced into the air storage unit 111, and the two heat-sealing points 162 are disposed below the two heat-sealing strips 161, so as to fix the ends of the first valve film 141 and the second valve film 142, which are located in the air storage unit 111, to the first air chamber film 1301 or the second air chamber film 1302.

The two symmetrically arranged heat sealing strips 161 are arranged along the air inlet direction of the inflation gas from the inflation channel heat sealing line 133, provide a flow guiding channel 160 for the inflation gas, and provide flow guiding and flow limiting effects for the inflation gas entering the gas storage unit 111, so that the inflation gas entering the gas storage unit 111 can be uniformly inflated.

When the inflation channel 112 is inflated through the inflation channel opening 1320, the inflation gas firstly enters the air inlet region 1121 in the inflation channel 112, then enters the buffer region 1122 through the buffer channel, and then enters each of the air storage units 111 along the air inlet 1110 and the heat-sealing unit 16.

In the process of inflating each of the air storage units 111, since the first and second valve films 141 and 142 are heat-sealed to the first and second air cell films 1301 and 1302 by the heat-sealing unit 16, as the inflating gas inside the air storage unit 111 increases, under the action of inflation gas, the first valve film 141 and the second valve film 142 will gradually separate from the second air cell film 1302 or the first air cell film 1301 as the first air cell film 1301 or the second air cell film 1302 separates, and as the pressure of the inflation gas within the gas storage unit 111 gradually increases, the first and second valve films 141 and 142 are closely adhered to the first or second air cell films 1301 and 1302 due to the pressurization of the inflation gas, thereby closing the gas inlet 1110 so that the inflation gas can be sealed from the gas storage unit 111.

In other words, when the inflation gas enters the gas storage unit 111 along the gas inlet 1110 and the heat-seal unit 16, the gas storage unit 111 expands more and more as more inflation gas is present in the gas storage unit 111, and the first cell film 1301 and the second cell film 1302 forming the gas storage unit 111 are also gradually separated. At this time, since the first and second valve films 141 and 142 are heat-sealed to the first and second air cell films 1301 and 1302 by the heat-sealing unit 16, the first and second valve films 141 and 142 gradually expand with the first and second air cell films 1301 and 1302, and are finally pressed and attached to the first and second air cell films 1301 and 1302 by the inflation gas.

It is emphasized that, since the heat-seal unit 16 is disposed inside the air storage unit 111, the buffer regions 1122 in the inflation channel 112 have no heat-seal line, and therefore the buffer regions 1122 are communicated with each other, so that the gas in the gas inlet region 1121 can uniformly enter the buffer regions 1122 through the buffer channels, and can uniformly enter the gas inlet 1110 through the buffer regions 1122 to inflate the air storage unit 111.

Figure 7 is a schematic view showing a modified example of the heat-seal unit 16' in the air-packing device 10 according to the present invention.

In this modified embodiment, the heat-sealing units 16' are arranged as one or more sets of triangular heat-sealing lines arranged symmetrically, so that the inflation gas can be introduced into the gas storage unit 111 at a uniform flow-limiting rate.

In detail, the triangular heat-seal lines are symmetrically disposed on the first and second valve membranes 141 and 142 and the first or second air cell membrane 1301 or 1302 in the air storage unit 111, and divide a channel between the first and second valve membranes 141 and 142 into two parts from top to bottom. Because the triangular heat-seal lines are symmetrically arranged relative to the air storage unit 111, two symmetrical drainage channels 160 'can be formed by two edges formed by the top-down of the triangular heat-seal lines, so that the inflation gas can be uniformly introduced into the air storage unit 111 by the two symmetrical drainage channels 160', and uneven pressure can not be generated on the separation seams 121 at the edges of the air storage unit 111, thereby further prolonging the service life of the air-packing device 10.

Besides, those skilled in the art can determine the specific shape of the heat-seal unit 16', such as regular and symmetrical wave shape or dot-and-dash shape, according to the actual situation, as long as the first valve film 141 and the second valve film 142 can be partially heat-sealed to the first air cell film 1301 or the second air cell film 1302, and the gas entering from the gas inlet 1110 is not influenced to the gas storage unit 111. In other words, as long as adopted with the utility model discloses the same or similar technical scheme, solved with the utility model discloses the same or similar technical problem to reached with the utility model discloses the same or similar technological effect all belongs to within the protection scope, the utility model discloses a specific embodiment does not use this as the limit.

Further, as shown in the drawings, there is a schematic view of a second embodiment of the air-packing device 10 of the present invention.

As shown, in contrast to the first embodiment of the air-packing device 10 of the present invention, the air-packing device 10 further includes a bending seam 134, and the bending seam 134 is heat-sealed to the first air cell film 1301 and the second air cell film 1302 and is located at the middle of the air container unit 111.

In detail, the folding seam 134 heat-seals a portion of each of the gas storage units 111 so that the inflation gas can fill the gas storage units 111 with the gas through the folding seam 134 in the gas storage units 111. That is, even if the folding seam 134 is heat-sealed in the air storage unit 111, the air storage unit 111 can be filled with the rated inflation gas at a time, so that the number of times and cost of inflating the air storage unit 111 are not increased, thereby increasing the efficiency of inflating the air-packing device 10.

The air storage units 111 can be folded along the folding slits 134, and since the folding slits 134 are located at the middle of the air storage units 111, the folded air storage units 111 are evenly distributed by the folding slits 134 and can be overlapped with each other.

The air-packing device 10 further includes two seams 135, and the two seams 135 are heat-sealed to the two side edges of the air-storage unit 111 equally divided by the folding seam 134 and overlapped with each other, so that the folded air-storage unit 111 divided into two parts by the folding seam 134 can be fixedly connected at the edges, and the air-packing device 10 forms a containing cavity 100 between the air-storage units 111 divided into two parts by the folding seam 134, thereby providing air cushion protection for a packaged article located in the containing cavity 100.

As a variation of the present modified embodiment of the present invention, the bending seam 134 may also be configured to heat-seal the middle portion of each of the air storage units 111 completely, so that each of the air storage units 111 is divided into two parts, and correspondingly, an air inlet structure identical to the air inlet channel 112 is further disposed at a position corresponding to the air inlet channel 112 at the bottom of the air-packing device 10, so that air can be introduced from the other side of each of the air storage units 111 that is not air-sealed by the bending seam 134.

In other words, the air-packing device 10 can be inflated by setting the structures on both sides of the bending slits 134 to be the same. The person skilled in the art can confirm the structure of the bending seam 134 according to the actual conditions, as long as the same or similar technical solution is adopted, the same or similar technical problem with the utility model is solved, and the same or similar technical effect is reached, all belong to the utility model discloses within the protection scope, the utility model discloses a specific embodiment is not so limited.

Preferably, the two seam joints 135 can be heat-sealed completely or partially at the overlapped edge of the gas storage unit 111, so long as the air-packing device 10 is formed to accommodate the cavity 100 and fix the articles accommodated therein and provide buffer protection, and those skilled in the art can determine two lengths of the seam joints 135 according to actual conditions, all belonging to the protection scope of the present invention, and the specific embodiments of the present invention are not limited thereto.

As shown in the drawings, there is a schematic view of a third embodiment of the air-packing device 10 of the present invention.

The third embodiment of the air-packing device 10 further includes even-numbered rows of folding slits 136 as compared to the first embodiment of the air-packing device 10. the even-numbered rows of folding slits 136 are provided to the air container unit 111 and heat-seal portions of the air container unit 111 to allow the air container unit 111 to be folded along the folding slits 136 before being filled with the inflation gas.

Further, the air-packing device 10 further includes at least two rows of the overlapped seams 137, two rows of the overlapped seams 137 are respectively located between even rows of the folded seams 136, and even rows of the folded seams 136 are equally distributed on both sides of the two rows of the folded seams 136 and are evenly arranged. The two rows of folding seams 137 are used for heat-sealing the air container 111 with the two adjacent upper and lower side edges of the air-packing device 10, so that the air-packing device 10 can be fixed by the two rows of folding seams 136 after being folded along the folding seams 134, thereby forming two accommodating spaces 200 at the same time to provide cushioning protection for two articles to be packed.

It should be noted that in the third embodiment of the air-packing device 10 of the present invention, not only the folding seam 136 does not affect the inflation of each of the air storage units 111, but also the two folding seams 137 does not affect the inflation of the air storage units 111.

The number of the folding seams 136 determines the shape of the gas storage unit 111 formed by folding along the folding seams 136, so that the number of the folding seams 136 can be modified according to actual situations.

In addition, in the another modified embodiment of the first embodiment of the method for manufacturing the air-packing device 10 of the present invention, since the shapes, sizes and structures of the two accommodating spaces 200 are identical, the folding seams 136 are arranged in even number on both sides of the two rows of the folding seams 137, and the folding seams 136 are arranged in even number on both sides of the two rows of the folding seams 137.

In the third embodiment of the present invention, the folding slits 136 are implemented in 6 rows and the folding slits 134 are implemented in 2 rows, thereby forming two square-shaped receiving spaces 200. Besides, a person skilled in the art can determine the position, the number and the distance between the folding seam 136 and the folding seam 137 according to the actual requirement of the two accommodating spaces 200, for example, the two accommodating spaces 200 are set to be different shapes or different sizes according to the actual situation, so long as the number, the position and the relative relationship between the folding seam 136 and the folding seam 137 are changed. In other words, as long as on the above-mentioned basis of disclosing of the utility model, adopted with the same or similar technical scheme of the utility model, solved with the same or similar technical problem of the utility model to reached with the same or similar technological effect of the utility model, all belong to within the protection scope, the utility model discloses a concrete implementation does not use this as the limit.

As shown in the drawings, there is a schematic view of a fourth embodiment of the air-packing device 10 in accordance with the present invention.

In the fourth embodiment of the air-packing device 10, as compared to the first embodiment of the air-packing device 10 of the present invention, the air-packing device 10 further includes a plurality of forming lines 138 and two intersecting lines 139. The plurality of forming seams 138 are partially heat sealed to the air storage unit 111 so that the air storage unit 111 can be folded along the plurality of forming seams 138 without affecting the air intake of the air storage unit 111.

The two intersecting seams 139 are partially heat-sealed at the left and right sides of the air-packing device 10 perpendicular to the forming seams 138, so that after the air storage unit 111 is bent along the forming seams 138, the overlapped parts of the left and right edges of the bent air storage unit 111 can be heat-sealed through the intersecting seams 139, so that the air-packing device 10 becomes an air-packing device 10 with a three-dimensional structure and has an accommodating space 300, thereby accommodating the object to be packed and providing buffer protection for the object to be packed.

In the fourth embodiment of the air-packing device 10 of the present invention, the air-packing device 10 further comprises a plurality of rows of continuously disposed closed seams 1381, i.e. one row of continuously disposed closed seams 1381 is continuously disposed at one of the air storage units 111, so that the continuity of the air storage units 111 the position of the closed seams 1381 can be overlapped.

The multiple rows of the closed seams 1381 are disposed in the air storage unit 111 and located in the middle of the two intersecting seams 139, and the multiple rows of the closed seams 1381 are symmetrically disposed and respectively close to the two intersecting seams 139, so that the air storage unit 111 can overlap the positions of the closed seams 1381 at the positions close to the two rows of the intersecting seams 139, and the air-packing device 10 forms the accommodating space 300 with a flat bottom to better accommodate the objects to be packed.

The plurality of closed seams 1381 are partially heat-sealed to each of the air storage units 111 so that any one of the air storage units 111 can be inflated at a time. In other words, any of the air storage units 111 does not have a portion where air cannot be taken in due to the arrangement of the closing seams 1381, thereby improving the efficiency of inflating the air-packing device 10.

It should be emphasized that, in the fourth embodiment of the air-packing device 10 of the present invention, the continuously arranged closed seams 1381 are implemented as 6 rows and the intersecting seams 139 are arranged on average near both sides, that is, 3 rows of the continuously arranged closed seams 1381 are arranged on 3 consecutive air storage units 111 near one side of the intersecting seam 139, and the other 3 rows of the continuously arranged closed seams 1381 are arranged on 3 consecutive air storage units 111 near the opposite side of the intersecting seam 139.

In addition, any row of the continuous closing seams 1381 is arranged along the direction of the intersecting seam 139 and in the middle of the intersecting seam 139, so that after the air storage unit 111 is folded along the forming seam 138 and heat-sealed and fixed along the intersecting seam 139, the closing seams 1381 are located at the bottom of the formed accommodating space 300.

In addition, in the fourth embodiment of the air-packing device 10 of the present invention, the length of the continuously arranged closed seam 1381 is one third of the length of the intersection 139 and is located at the middle position of the intersection 139, so that the degree of the air storage unit 111 at both sides of the closed seam 1381 is equal, and the width of the bottom of the accommodating space 300 and the heights of both sides are the same after the air storage unit 111 is heat-sealed along the intersection 139.

The length of the continuously arranged closed seams 1381 and the number of rows of the closed seams 1381 can be determined by those skilled in the art according to practical situations, and mainly depends on the structure and shape of the accommodating space 300 to be formed.

In other words, as long as on the above-mentioned basis of disclosing of the utility model, adopted with the same or similar technical scheme of the utility model, solved with the same or similar technical problem of the utility model to reached with the same or similar technological effect of the utility model, all belong to within the protection scope, the utility model discloses a concrete implementation does not use this as the limit.

1003: heat-sealing the heat-sealing unit 16 to the air storage unit 111 to fix the first valve film 141 and the second valve film 142 to one of the two or more layers of the flexible films, thereby forming the one-way inflation valve 14;

1004: at least two separation seams 121 are heat-sealed along the charging direction of the inflation gas at both sides of the gas inlet 1110 to form at least one gas storage unit 111; and

1005: a reinforcing plastic sealing line 151 is heat sealed to the inflation channel 112, and the reinforcing plastic sealing line 151 is disposed along the intake direction of the inflation gas, thereby forming the reinforcing structure 15.
