Description

Technical Field

[0001] The present invention relates to the field of packaging and transportation, and further to an air-filled cushioning packaging device, which is particularly suitable for packaging a flat-panel electronic product and providing cushioning protection for the flat-panel electronic product during transportation to prevent the flat-panel electronic product from being damaged during transportation. Background Art

[0002] With the development of science and technology, televisions are gradually becoming thinner and lighter, and more and more ultra-thin LCD TVs are appearing in people's lives. Take LCD TV as an example. LCD TVs consist of two sheets of glass and liquid crystal between the two sheets of glass. Liquid crystal is an organic compound with regular molecular arrangement. It is a transparent liquid state when heated and a turbid solid state with crystal particles after cooling. By adding voltage to the liquid crystal between the two sheets of glass, the picture is reproduced through the change of molecular arrangement and the tortuous change. The screen creates the picture through the collision of electron groups and forms the picture through the perspective emission of external light.

[0003] It should be understood by those skilled in the art that, due to limitations in the structure of liquid crystal flat panel electronic products, liquid crystal flat panel electronic products are easily damaged by collisions during transportation, thus affecting the normal use of liquid crystal flat panel electronic products. It is worth mentioning that, with the development of e-commerce, more and more consumers choose to purchase liquid crystal flat panel electronic products online, which often requires long-distance transportation and is more likely to cause damage to liquid crystal flat panel electronic products during transportation.

[0004] In order to prevent the LCD flat panel electronic products from being damaged due to collision during transportation, a common practice is to place foam cushioning materials in the box that packs the LCD flat panel electronic products to provide cushioning protection for the LCD flat panel electronic products during transportation.

[0005] It should be pointed out that the foam cushion is solid. When packaging liquid crystal flat panel electronic products, in order to make the foam cushion and the liquid crystal flat panel electronic products fit better, it is necessary to open a groove on the foam cushion so that the liquid crystal flat panel electronic products can fit better on the foam cushion and achieve a better cushioning effect. It is understandable that opening a groove on the foam cushion requires a special mold opening tool, which increases the cost and labor intensity of packaging.

[0006] On the other hand, foam cushioning materials are usually solid, which will take up a lot of storage and transportation space, increasing transportation costs. In addition, due to the huge size of LCD flat panel electronic products, the volume of foam cushioning materials required is also quite large, which is easy to break during transportation, and lose the cushioning protection function, and even cause damage to the LCD flat panel electronic products.

[0092] Reference Manual Attached Fig. 10A Specifically, the inflatable buffer body 10 further includes a first gas storage chamber film 61 and a second gas storage chamber film 62, and a gas storage chamber 610 formed between the first gas storage chamber film 61 and the second gas storage chamber film 62, and the gas storage chamber 610 is suitable for being filled with gas. Before the gas storage chamber 610 is not filled with gas, the first gas storage chamber film 61 and the second gas storage chamber film 62 are attached to each other, and the inflatable buffer body 10 is in a flat state, which is convenient for the storage and carrying of the inflatable buffer packaging device 100 for flat electronic products. After the gas storage chamber 610 is filled with gas, the first gas storage chamber film 61 and the second gas storage chamber film 62 are separated from each other, and the inflatable buffer body 10 has a buffer protection function by virtue of the gas stored in the gas storage chamber 610.

[0093] The inflatable buffer body 10 further includes a group of spaced heat seal lines 63, which are heat-sealed to form the first gas storage chamber membrane 61 and the second gas storage chamber membrane 62 of the inflatable buffer body 10, and the spaced heat seal lines 63 divide the gas storage chamber 610 into a plurality of sub-gas storage chambers 6100.

[0094] The inflatable buffer body 10 further has a connecting channel 620, and the connecting channel 620 is connected to each of the sub-gas storage chambers 6100 of the gas storage chamber 610, and gas can be filled into each of the sub-gas storage chambers 6100 of the gas storage chamber 610 through the connecting channel 620. The connecting channel 620 has an opening 6201, and gas can be filled into the connecting channel 620 through the opening 6201.

[0095] The inflatable buffer body 10 further includes a set of one-way inflation valves 64, which are arranged between the first gas storage chamber membrane 61 and the second gas storage chamber membrane 62, and the one-way inflation valves 64 connect the communication channel 620 and each of the sub-gas storage chambers 6100 of the gas storage chamber 610, and the gas in the communication channel 620 can enter each of the sub-gas storage chambers 6100 of the gas storage chamber 610 through the one-way inflation valves 64. Preferably, each of the one-way inflation valves 64 corresponds to a sub-gas storage chamber 6100, and is used to fill the sub-gas storage chamber 6100 with gas.

[0096] The one-way inflation valve 64 further includes a first valve film 641 and a second valve film 642, and the first valve film 641 and the second valve film 642 overlap each other and are arranged between the first gas storage chamber film 61 and the second gas storage chamber film 62. The one-way inflation valve 64 further has a valve channel 643 formed between the first valve film 641 and the second valve film 642, and the valve channel 643 connects the communication channel 620 and the sub-gas storage chamber 6100, and the gas in the communication channel 620 can enter the sub-gas storage chamber 6100 through the valve channel 643.

[0097] The one-way inflation valve 64 further includes a heat-resistant joint 644, which is arranged between the first valve membrane 641 and the second valve membrane 642. The width of the heat-resistant joint is adapted to the width of the valve channel 643. The heat-resistant joint 644 is used to prevent the first valve membrane 641 and the second valve membrane 642 from being heat-sealed together during the heat-sealing process.

[0098] The inflatable buffer body 10 further includes a group of heat sealing points 65, which are used to heat seal the first valve film 641 and the second valve film 642 at one end away from the communication channel 620 to the first gas storage chamber film 61 or the second gas storage chamber film 62. The first valve film 641 and the second valve film 642 at one end away from the communication channel 620 extend into the sub-gas storage chamber 6100. During the process of filling the gas storage chamber 610 with gas, the gas in the connecting channel 620 can enter the sub-gas storage chamber 6100 through the valve channel 643. When the gas in the sub-gas storage chamber 6100 reaches a certain level, under the action of the pressure of the gas in the sub-gas storage chamber 6100, the first valve membrane 641 and the second valve membrane 642 are tightly pressed against the first gas storage chamber membrane 61 or the second gas storage chamber membrane 62, so that the valve channel 643 formed between the first valve membrane 641 and the second valve membrane 642 is closed, preventing the gas in the sub-gas storage chamber 6100 from leaving through the valve channel 643, thereby achieving the purpose of one-way inflation.

[0099] Reference Fig. 10B , which shows a structural schematic diagram of a modified embodiment of the one-way inflation valve provided by the present invention. In this modified embodiment, the one-way inflation valve 64 further includes a check film 644. The check film 644 is arranged between the first valve film 641 and the second valve film 642. The upper end of the check film 644 is heat-sealed and connected to the upper end of the second valve film 642, and the lower end of the check film 644 is located between the lower end of the first valve film 641 and the lower end of the second valve film 642, and the length of the check film 644 is less than the length of the first valve film 641 and the second valve film 642.

[0100] The valve channel 643 is formed between the first valve film 641 and the check film 644. The gas in the communication channel 620 can enter the gas storage chamber 610 through the valve channel 643. When the gas content in the gas storage chamber 610 reaches a certain level, under the action of the gas pressure in the gas storage chamber 610, the lower ends of the first valve film 641, the second valve film 642 and the check film 644 are tightly pressed against the first gas storage chamber film 61, thereby closing the valve channel 643 formed between the first valve film 641 and the check film 644, and preventing the gas in the gas storage chamber 610 from leaking.

[0101] In this preferred embodiment, when the gas in the gas storage chamber 610 leaks through the first valve film 641 and the second valve film 642, when the gas leaks between the check film 644 and the second valve film 642, since the upper end of the check film 644 is heat-sealed and connected to the upper end of the second valve film 642, the gas cannot leak to the outside through the check film 644 and the second valve film 642. When the amount of gas leaked between the check film 644 and the second valve film 642 reaches a certain level, under the action of the gas pressure between the check film 644 and the second valve film 642, the check film 644 is tightly pressed against the first valve film 641, so that the valve channel 643 can be further sealed, achieving the effect of less leakage as the leakage increases.

[0102] Reference Fig. 10C , which shows a third variant embodiment of the one-way inflation valve provided by the present invention. In this variant embodiment, the one-way inflation valve 64 further includes a reinforcing film 645. The reinforcing film 645 is disposed between the second valve film 642 and the second gas storage chamber film 62, and the upper end of the reinforcing film 645 is heat-sealed and connected between the upper end of the second valve film 642 and the second gas storage chamber film 62, and the lower end of the reinforcing film 645 is movably located between the lower end of the second valve film 642 and the second gas storage chamber film 62.

[0103] When the gas content filled in the gas storage chamber 610 reaches a certain level, under the effect of the gas pressure in the gas storage chamber 610, the lower ends of the first valve film 641, the second valve film 642 and the reinforcing film 645 are tightly pressed against the first gas storage chamber film 61, thereby sealing the valve channel 643 between the first valve film 641 and the second valve film 642 to prevent leakage of gas entering the gas storage chamber 610. The reinforcing film 645 is located on the outer side of the second valve film 642, and the check film 305 is in direct contact with the gas in the gas storage chamber 610, which can protect the second valve film 642 and enhance the sealing effect.

[0104] Reference Fig. 10D, which shows a fourth modified embodiment of the one-way inflation valve provided by the present invention. In this modified embodiment, the upper ends of the first valve film 641 and the second valve film 642 of the one-way inflation valve 64 extend upward to the outside of the first gas storage chamber film 61 and the second gas storage chamber film 62. The upper peripheral heat sealing line 30511 of the peripheral heat sealing line 3051 heat-seals and connects the upper end of the first valve film 641 and the upper end of the second valve film 642, and the communication channel 620 is formed between the upper end of the first valve film 641 and the upper end of the second valve film 642.

[0105] In this modified embodiment, the upper end portions of the first valve membrane 641 and the upper end portions of the second valve membrane 642 are extended to the outside of the first gas storage chamber membrane 61 and the second gas storage chamber membrane 62, and the connecting channel 620 is formed between the upper end portions of the first valve membrane 641 and the upper end portions of the second valve membrane 642, so as to prevent the upper end portions of the first valve membrane 641 and / or the second valve membrane 642 from folding and blocking the valve channel 643 during inflation.

[0106] It should be understood by those skilled in the art that, in some other preferred embodiments of the present invention, the inflatable buffer body 10 may also not have the one-way inflation valve 64, and gas is filled into the gas storage chamber 610 between the first gas storage chamber membrane 61 and the second gas storage chamber membrane 62 during the process of heat sealing the first gas storage chamber membrane 61 and the second gas storage chamber membrane 62.

[0107] It should be understood by those skilled in the art that when packaging articles with different weights, the air column size, suspension height and buffer distance of the gas-filled buffer body 10 can be implemented as different sizes, that is, the gas-filled buffer body 10 can be implemented as a variety of different specifications to provide better buffer protection for the packaged articles of different specifications, wherein the suspension height refers to the height of the buffer cavity 120, that is, the distance from the opening of the buffer cavity 120 to the bottom wall 113, and the buffer distance refers to the overlapping thickness of the first side wall 111 and the third side wall 123, or the overlapping thickness of the second side wall 112 and the fourth side wall 124. Specifically, refer to Table 1 below, which shows the corresponding relationship between the air column size, suspension height, buffer distance of the gas buffer body 10 and the weight of the packaged article and the corresponding drop height.

Preferably, the distance between the first side wall 111 and the third side wall 123 and the distance between the second side wall 112 and the fourth side wall 124 are respectively the distances of 3 to 6 gas columns of gas buffer bodies, so as to provide buffering protection for the items to be packaged at the side.

[0108] Referring to Table 1 below, the range of the suspended height of the bottom wall 113 is 0 to 100 mm, and the range of the gas column size of the gas buffer body 10 is 20 to 100 mm. When the range of the suspended height of the bottom wall 113 is 5 to 100 mm, and the range of the gas column size of the gas buffer body 10 is 20 to 40 mm, it is suitable for packaging articles of 0 to 10 kg. When the range of the suspended height of the bottom wall 113 is 5 to 60 mm, and the range of the gas column size of the gas buffer body 10 is 30 to 60 mm, it is suitable for packaging articles of 10 to 19 kg.

When the suspended height of the bottom wall 113 is in the range of 5 to 20 mm and the gas column size of the gas buffer body 10 is in the range of 40 to 100 mm, it is suitable for packaging articles weighing 28 to 45 kg.

[0109] With reference to Table 1 below, the buffer distance ranges from 15 to 100 mm. When the buffer distance ranges from 15 to 100 mm, the suspended height ranges from 5 to 100 mm, and the gas column size range of the gas buffer body 10 ranges from 20 to 40 mm, it is suitable for packaging articles of 0 to 10 kg.

[0112] Reference Manual Attached Figures 11 to 13 ,, which shows a variant implementation of the inflatable cushioning packaging device 100 provided by the present invention. The difference between this preferred embodiment and the above preferred embodiment is that, in this variant implementation, the inflatable cushioning packaging device 100 further includes a suspension support body 20, and the suspension support body 20 is arranged in the installation cavity 110. The suspension support body 20 is used to support the end of the flat-panel electronic product 200 to be suspended in the installation cavity 110, so as to further increase the cushioning protection effect of the flat-panel electronic product 200.

In other words, the second bent heat-sealing line 132 heat-seales one end of the suspension support body 20 to the connection between the first top wall 121 and the first side wall 111, and the fifth bent heat-sealing line 135 heat-seales the other end of the suspension support body 20 to the connection between the second top wall 122 and the second side wall 112. The length of the suspension support 20 is less than the sum of the lengths of the first side wall 111, the second side wall 112, and the bottom wall 113, so when the inflatable buffer 10 is inflated, the suspension support 10 can be suspended in the installation cavity 110, with a predetermined distance between the suspension support 10 and the bottom wall 113. It should be pointed out that in this preferred embodiment, when the inflatable buffer 10 is filled with gas, the suspension support 10 cannot be filled with gas, so as to reduce the volume occupied by the suspension support 10.

The difference between this preferred embodiment and the above preferred embodiment is that, in this variant embodiment, the width of the sub-gas storage chamber of the third side wall 123 is smaller than the width of the sub-gas storage chamber of the first side wall 111, and the width of the sub-gas storage chamber of the fourth side wall 124 is smaller than the width of the sub-gas storage chamber of the second side wall 112, thereby being able to reduce the overall thickness of the inflatable cushioning body 10 to a certain extent and reduce the space occupied by the inflatable cushioning body 10.

[0117] Specifically, in this preferred embodiment, the inflatable cushioning packaging device 100 further includes a group of first shrinkage heat sealing lines 31 and a group of second shrinkage heat sealing lines 32, and the first shrinkage heat sealing lines 31 and the second shrinkage heat sealing lines 32 are heat-sealed to form the third side wall 123 and the fourth side wall 124 of the inflatable cushioning body 10, respectively, and are used to reduce the size of the sub-gas storage chamber of the third side wall 123 and the fourth side wall 124, respectively.

[0118] Reference Manual Attached Fig.14 Preferably, the first shrink heat seal line 31 is heat-sealed and formed on the third side wall 123 along the length direction of the sub-gas storage chamber of the third side wall 123. Preferably, in this preferred embodiment, each of the sub-gas storage chambers of the third side wall 123 is heat-sealed to form a first shrink heat seal line 31, and each of the first shrink heat seal lines 31 divides the corresponding sub-gas storage chamber of the third side wall 123 into two parts, so as to reduce the thickness of the sub-gas storage chamber of the third side wall 123 after inflation. Preferably, in this preferred embodiment, the first shrink heat seal line 31 extends between the first bending heat seal line 131 and the side edge of the third side wall 123 away from the first top wall 121, and the length of the first shrink heat seal line 31 is consistent with the distance between the first bending heat seal line 131 and the first bending heat seal line 131 and the side edge of the third side wall 123 away from the first top wall 121. In some other preferred embodiments of the present invention, the length of the first shrink heat seal line 31 can also be less than the distance between the first bending line 131 and the edge of the third side wall 123 away from the first top wall 121.
