Problems solved by technology

[0003]However, in order to provide a better buffer protection effect, this kind of buffer air bag is quite bulky, so it takes a lot of time to inflate, which is quite time-consuming and laborious. High-pressure gas is filled into the buffer air bag, which may easily cause the check valve of the buffer air bag to be damaged and cannot hold the air, or cause the outer membrane of the buffer air bag to be damaged and deflated
Moreover, such cushioning airbags are often scratched and damaged by the sharp corners or sharp corners of the articles in the container, causing the gas in the cushioning airbags to leak out and lose the function of cushioning protection, and it must be discovered when the articles are removed from the container , and at this time, the item is also scratched or damaged due to the lack of buffered intermediate protection during transportation
[0004] From this we can know how to improve the structure of the buffer air bag and its check valve, increase the inflation speed and reduce the time required to inflate the buffer air bag, and then improve the The structure of the buffer air bag prevents the buffer air bag from being easily damaged by sharp corners and sharp corners of the goods in the container, resulting in gas leakage and loss of the buffer protection function. This is an urgent problem for those skilled in the art to solve

[0036] Figure 1A , Figure 1B , figure 2 and image 3 Shown is a high-pressure inflatable air sealing body and its air-stop valve according to the first embodiment of the present invention. The air-sealing body of the present invention includes: an air-stop valve 10 and at least one air column 20 .

[0037] The air column 20 includes two outer membranes 2a and 2b stacked up and down, and the air stop valve 10 is interposed between the two outer membranes 2a and 2b, as Figure 1A and Figure 1B As shown, after the two outer films 2a, 2b are heat-sealed and bonded along the peripheral heat-sealing lines 41, 42, 51, 52 shown in the figure, an air column 20 for storing gas is formed between the two outer films. . Wherein the stop valve 10 is formed on the gas column by being heat-sealed by a peripheral heat-sealing line of the gas column 20 .

[0038] Such as figure 2 As shown, the stop valve 10 includes two first inner films 11a and 11b stacked up and down, and two second...

[0045] Figure 4 Shown is a high pressure inflatable air sealing body and its air stop valve according to the second embodiment of the present invention.

[0046] with the first embodiment Figure 1A The difference is that this embodiment also has a first gas channel 11e. In this embodiment, the two first inner films 11a, 11b are heat-sealed under the first air inlet 11d, and a first gas channel 11e is formed between the two first inner films. One end of the gas channel is connected to the first gas inlet 11d, that is, the upper end of the first gas channel starts from the peripheral heat seal line 41, and the width of the end of the first gas channel connected to the first gas inlet 11d is greater than that of the other end. The width makes it easy for gas to enter the first gas inlet 11d and not easy to escape, but the shape of the first gas channel 11e is not limited to this, and it can also be arc-shaped, dot-shaped or broken line-shaped, or its shape can be adjusted acco...

[0048] Figure 5 and Figure 6 Shown is the high pressure inflatable air sealing body and its air stop valve according to the third embodiment of the present invention.

[0049] In this embodiment, the two superimposed second inner membranes 12a, 12b are located in the upper half between the two upper and lower first inner membranes 11a, 11b, that is, most of the two second inner membranes are exposed. In the air column 20, the rest is located in the air column. The tops of the two second inner membranes 12a, 12b are aligned with the tops of the two first inner membranes 11a, 11b, and the bottoms of the two second inner membranes are located in the air column 20.

[0050] The first heat-resistant material 12c is pre-coated between the two second inner films 12a and 12b, and the first heat-resistant material 12c runs through the peripheral heat seal line 41 of the gas column, and the heat-resistant heat is applied between the two second inner films on the above-mentioned peri...

Abstract

The invention provides a high-pressure aerated air sealing body, which comprises an air stopping valve and at least one air column, wherein the air column is formed by peripheral heat-sealing lines of two outer membranes in a heat sealing way between the two outer membranes; the air stopping valve is formed on the air column by one peripheral heat-sealing line of the air column in a heat sealing way; the air stopping valve comprises two first inner membranes, at least one group of two second inner membranes and at least one second air inlet; the two first inner membranes are arranged between the two outer membranes of the air column, and part of the first inner membranes can be exposed out of the air column; the second inner membranes are arranged between the two first inner membranes; and the second air inlet is formed between the second inner membranes by bonding the first inner membranes and the second inner membranes in a heat sealing way. The air stopping valve can not only have very good strength to adapt to the high-pressure fast aeration, but also realize very good air-closing and air-stopping effects.

Description

technical field [0001] The invention relates to an air sealing body and its air stop valve, in particular to an air sealing body capable of high-pressure inflation and its air stop valve. Background technique [0002] Generally, when large-scale items are transported in containers, buffer air bags are placed between the items to cushion and protect the items, reduce scratches or damage caused by collisions during transport, and increase the rate of qualified products during transport. [0003] However, in order to provide a better cushioning protection effect, the volume of this cushioning airbag is quite large, so it takes a lot of time to inflate, which is quite time-consuming and laborious. If the cushioning airbag is filled with high-pressure gas, it is easy to cause the reverse of the cushioning airbag. The stop valve is damaged and cannot hold the air, or the outer membrane of the buffer air bag is damaged and deflated. Moreover, such cushioning airbags are often scra...
