Problems solved by technology

[0002] The traditional way of cushioning packaged items is to protrude from a plastic sheet with a plurality of raised small airbags, and wrap the plastic film on the outer periphery of the article to achieve shock absorption and cushioning. However, the shock absorption capacity of the small airbags is limited. Large vibration or impact load can not achieve the effect of cushioning and shock absorption, so a kind of cushioning material with gas packaging bag as the coating has been developed.
[0003] Although the gas packaging bag uses gas as the buffer medium of the item to provide the function of buffering and protecting the item, the item will inevitably shake or collide during the handling process. The gas packaging bag made of polyethylene (PE) material It is easy to be punctured by the sharp corner of the article or the hardware material with sharp corners. Once a small hole appears, the gas in the gas packaging bag will leak out, which is easy to cause damage or scratches to the packaging. This kind of gas packaging bag See U.S. No. 4850912 patent "Container for sealingly containing a fluid", U.S. No. 5261466 patent "process for continuously filling fluid into a plurality of sealed bags" bags)" and Japanese Patent Application No. 5-95851 "Sealed Bags for Fluids"
[0004] It can be seen from this that how to improve the structure of the gas packaging bag, solve the problem that the gas packaging bag loses the cushioning protection due to gas leakage, and then provide better cushioning and shock absorption, is a problem that those skilled in the art want to solve urgently

Embodiment 1

[0030] figure 1 , figure 2 ,image 3, Figure 4A , Figure 4B with Figure 4C Shown is a hammock type air shock boot according to a first embodiment of the present invention.

[0031] The hammock type air shockproof cover of the present invention is used to cover articles and provide buffer protection for the articles, which includes: air column sheet 2 and buffer sheet 5 .

[0032] Described air column sheet 2 comprises two outer films 2a, 2b stacked up and down, and two outer films are made of polyethylene (polyethylene, PE), and the peripheries of two outer films are bonded by heat-sealing lines so that the air column sheet has The first heat-sealed edge 21a, the second heat-sealed edge 22a, the joint edge 21c and the bottom side 21d. The first heat-sealing line 3b is arranged on the top of the air column sheet and lower than the upper peripheral heat-sealing line 3a, thus forming a possible gap between the upper peripheral heat-sealing line 3a and the first heat-seali...

Embodiment 2

[0043] Figure 5 with Image 6 It is a cross-sectional view and a schematic diagram of a covered article according to the second embodiment of the present invention. See Figure 5 , the difference from the first embodiment is that in this implementation, the bottom side 21c on the first buffer wall 21 and the bottom side on the second buffer wall 22 are not heat-sealed, so that the accommodating space 6 is an open space. When the buffer sheet 5 wraps the article 100, the buffer sheet is pressed down under force to slow down the shaking of the article 100, thereby achieving the function of buffering and shock absorption.

[0044] exist Image 6 Among them, after the buffer sheet 5 is folded in half, its left and right sides are bonded to form two left and right joints 51, so when the object shakes violently and the buffer sheet 5 shakes left and right, the buffer sheet 5 can first slow down the shaking of the object 100, and then The article 100 is buffered and protected by...

Embodiment 3

[0046] Figure 7 with Figure 8 The third embodiment of the present invention. Wherein, the first buffer wall 21 is provided with a plurality of first node interval lines 210b, and the second buffer wall 22 is also provided with a plurality of second node interval lines 220b. Respectively bend the gas column along the bending line 230, two first node interval lines 210b, and two second node interval lines 220b, and then bond the first heat-sealing edge 21a and the second heat-sealing edge 22a with heat-sealing means, so that the first An accommodating space 6 is enclosed between the buffer wall 21 and the second buffer wall 22 , Figure 8 Among them, the accommodating space 6 is roughly hexagonal, and the length of each side changes with the distance between the spacing lines. When changing the number or position of the interval lines on the first buffer wall 21, or changing the number or position of the interval lines on the second buffer wall 22, the accommodating space 6...

Abstract

The invention relates to a hammock-typed air shockproof jacket, which comprises a gas-column plate and a buffering plate; the gas-column plate comprises two extimas with the periphery being agglutinated in heat-sealing way and a plurality of independent gas columns, and the gas-column plate is provided with a first heat-sealing edge and a second heat-sealing edge; the gas columns are provided with a plurality of bending points that are used for splicing the two extimas in heat-sealing way, and the bending points stay on the same straight line to form a bending line, and the bending line divides the gas-column plate into a first buffering wall and a second buffering wall, which are communicated with each other; the first heat-sealing edge is arranged on the first buffering wall, and the second heat-sealing edge is arranged on the second buffering wall; after the gas-column plate is bent along with the bending line and is charged with air, and after the first and the second heat-sealing edges are agglutinated in heat-sealing way, an accommodating space is formed by the first buffering wall and the second buffering wall as well as the gas-column plate; the buffering plate is suspended inside the accommodating space; a holding space that is used for coating the articles is arranged inside the buffering plate. The buffering plate can slow down the shaking of the articles, and the first and the second buffering walls can further provide buffering shock-absorption protection for the articles.
