Background technique

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 loads cannot achieve the effect of cushioning and shock absorption, so a kind of cushioning material with gas packaging bags as covering has been developed.

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. Patent No. 4850912 "Container for sealingly containing a fluid", U.S. Patent No. 5261466 "Method for continuously filling fluid into a plurality of sealed bags" (Process for continuously filling fluid into a plurality of closed bags) bags)" and Japanese Patent Application No. 5-95851 "Sealed Bags for Fluids".

It can be seen from this that how to improve the structure of the gas packaging bag, solve the problem of the gas packaging bag losing cushioning protection due to gas leakage, and provide better cushioning and shock absorption, is a problem that those skilled in the art want to solve urgently.

Detailed ways

Embodiment one

Fig. 1, Fig. 2, Fig. 3, Fig. 4A, Fig. 4B and Fig. 4C show the hammock type air shockproof sleeve of the first embodiment of the present invention.

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 .

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-sealing line 3b in the two outer films. The air-flowing space, called the air-filled channel 9, forms a plurality of independent gas columns 20 between the first heat-sealing line 3b and the lower peripheral heat-sealing line 3c.

As shown in Figure 2, there are also two inner membranes 1a and 1b stacked up and down inside the two outer membranes, and a plurality of heat-resistant materials 1c are coated on the inner membranes at intervals, and the heat-resistant materials 1c can be used as air circulation The passage, and the two inner membranes and the heat-resistant material 1c both extend from the air channel 9 to the air column 20 . The heat-resistant material 1c runs through the first heat-sealing line 3b, and forms a plurality of air inlets 2e at the intersection with the first heat-sealing line 3b and between the two inner films, and each air inlet 2e is connected to an air column 20, namely : the air inlet 2e communicates the air column 20 with the inflatable channel 9, and one side of the inflatable channel 9 is provided with an inflatable port 9a. Each gas inlet 2e is connected to the gas channel 14 in the gas column 20. The gas channel 14 is formed on the two inner films after coating the heat-resistant material 1c between the two inner films by means of heat sealing. Between them, gas passages 14 start from the first heat-sealing line 3b and extend downward for a certain length, and the heat-resistant material 1c is formed between the gas passages 14 and is shorter than the length of the gas passages.

After the gas entering the inflation port 9a expands the inflation channel 9, the two outer membranes 2a and 2b will automatically pull apart to open the gas inlet 2e, so that the gas enters the air column 20 through the gas inlet 2e and along the gas channel 14 to make the The air column is inflated with air. After the air column 20 is inflated, its internal pressure presses the two inner membranes 1a and 1b so that the two inner membranes are tightly pressed against one piece of outer membrane 2a or 2b. In addition, the two inner membranes 1a and 1b may not be side-attached in the outer membrane 2a or 2b, but suspended in the air column 20, thereby covering the gas channel 14 to seal the air column 20, so that the gas in the air column 20 cannot escape. Release to achieve the effect of holding breath.

Each air column 20 is provided with a bending point 23 for heat-sealing the two outer films, and these bending points 23 are on the same straight line to form a bending line 230 . The bending line 230 divides the air column sheet into a first buffer wall 21 and a second buffer wall 22 which communicate with each other up and down. The first heat-sealed edge 21 a is located on the first buffer wall 21 , and the second heat-sealed edge 22 a is located on the second buffer wall 22 . On the air column of the first buffer wall 21, there is a first node 21b for heat-sealing the two outer films. These first nodes 21b are all on the same straight line to form a first node interval line 210b. On the air column of the second buffer wall 22, there is a second node 22b for heat-sealing the two outer films. These second nodes 22b are all on the same straight line to form a second node spacing line 220b.

After inflating the air column, bend the air column along the bending line 230, the first node interval line 210b, and the second node interval line 220b, and then bond the first heat-sealed edge 21a and the second heat-sealed edge 22a by heat-sealing means , so that between the first buffer wall 21 and the second buffer wall 22, an accommodating space 6 with two openings is formed. The accommodating space 6 in FIG. The length of each side of the quadrilateral will change accordingly. In addition, only one first node interval line 210b and one second node interval line 220b are provided in FIG. There may be one first node interval line 210b, and the second buffer wall 22 may also be provided with two, three, four, five, etc. multiple second node interval lines 220b. And the spacing lines are parallel to each other, and their spacing is arbitrary. As the number of interval lines and the positions between them change, the accommodating space 6 presents polygons of various shapes.

The upper end and the lower end of the buffer sheet 5 are respectively provided with a plurality of heat-seal points 5a, 5b, and the upper end of the buffer sheet 5 is heat-sealed and bonded to the joint edge 21c on the first buffer wall 21 through the heat-seal points 5a. The heat-sealing point 5 b makes the lower end of the buffer sheet 5 and the joint edge 21 c on the second buffer wall 22 heat-sealed and bonded. The upper and lower ends of the buffer sheet can also be directly heat-sealed and bonded to the joint edge 21c. Then, the bottom side 21d on the first buffer wall 21 is heat-sealed and bonded to the bottom side on the second buffer wall 22 , so as to close the opening at one end of the accommodating space 6 . The buffer sheet 5 is suspended in the accommodating space 6 and is slightly in the shape of a hammock. At this time, there is a distance between the bottom end of the buffer sheet 5 and the bottom side 21d after bonding, so that the buffer sheet 5 is not in harmony with the bottom side. 21d adjacent gas columns are in contact. A receiving space 50 is formed in the buffer sheet 5 for wrapping the article 100 .

In the present invention, after the gas is filled into the gas column, the first buffer wall 21 and the second buffer wall 22 will be inflated and expanded to have the effect of cushioning and shock absorption.

The buffer sheet 5 is made of soft material, such as: polyvinyl chloride (Polyvinylchloride, PVC), polypropylene (Polypropylene, PP), expanded polyethylene (EPE), expanded polypropylene (EPP), cloth, foam Cotton, polyethylene (polyethylene, PE) made of small particle bubble cloth and other materials can also be made of corrugated paper, paper or similar paper materials.

As shown in Fig. 4A, Fig. 4B and Fig. 4C, when the article 100 is wrapped with the hammock type air shockproof cover of the present invention, the article 100 can be provided with buffer protection, although the buffer sheet 5 is produced downward by the pressure of the article 100 There is a displacement, but the buffer sheet still maintains a distance from the air column 20 connected to the bottom side 21d without contacting the air column. When the item 100 shakes during transportation, the buffer sheet first slows down the shaking of the item 100 , and the first buffer wall 21 and the second buffer wall 22 further provide buffer protection for the item 100 . Only when the article shakes violently and the buffer sheet 5 is forced downward, the buffer sheet will come into contact with the air column 20 connected to the bottom side 21d, and provide further shock-absorbing protection to the article through the air column .

In addition, the present invention can also prevent the object 100 from directly abutting against the first buffer wall 21 and the second buffer wall 22, preventing the object from piercing the first buffer wall 21 and the second buffer wall 22 and causing gas leakage, which has good Efficacy of buffer protection.

Embodiment two

Fig. 5 and Fig. 6 are the sectional view and the schematic diagram of the wrapped article according to the second embodiment of the present invention. 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 object 100, the buffer sheet is pressed down by force to slow down the shaking of the object 100, thereby achieving the function of buffering and shock absorption.

In Fig. 6, 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 article shakes violently and the buffer sheet 5 shakes left and right, the buffer sheet 5 can first slow down the movement of the article 100. Shaking, the first buffer wall 21 and the second buffer wall 22 are used to buffer and protect the object 100 , thereby providing secondary buffer and shock-absorbing protection for the object 100 . In addition, the present invention can prevent the object 100 from directly abutting against the first buffer wall 21 and the second buffer wall 22 , preventing the object from piercing the first buffer wall 21 and the second buffer wall 22 and causing gas leakage, thereby losing the effect of buffer protection.

In FIG. 8, the accommodation space 6 is roughly hexagonal, and the length of each side changes with the distance between the interval 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 will present polygons of different shapes, such as triangles, quadrangles, and five sides. Shapes, hexagonal tables, heptagons, etc.

In the above-mentioned embodiment of the present invention, the upper and lower ends of the buffer sheet 5 can be bonded by heat-sealing means to be fixed on the joining edge of the first buffer wall 21 and the second buffer wall 22; the buffer sheet 5 may not be provided separately, Instead, the joint edge on the first buffer wall 21 is extended outward to form the buffer sheet 5, and one end extended is bonded to the joint edge on the second buffer wall 22, so that the buffer sheet 5 is suspended in the accommodating space 6 inside and in the shape of a hammock. Alternatively, the joint edge on the second buffer wall 22 can also be extended outward to form the buffer sheet 5 .
