Description

Buffer air bag

The present invention relates to a package structure, and more particularly to a cushion air bag structure.

When general items need to be transported or shipped, most of them will be packed. In order to avoid collision damage during the transportation, the paper is currently covered with bubble paper or styrofoam. However, in actual experience, bubble paper and styrofoam still have poor buffering effect and easily cause damage to the article. In view of the above problems, a gas packaging bag has been developed which forms a gas column via heat sealing for charging a gas to enable the gas packaging bag to have a buffering effect.

At present, most of the manufacturing process of gas packaging bags is to heat seal a plurality of films to form a gas column, and then bend the gas column into a bag shape to accommodate the coated articles. However, the practical experience of this practice is The following problems have been found. The reason is that the air column sheet will greatly reduce the space for accommodating articles after bending, which makes the conventional gas packaging bag unsuitable for large items (such as LCD TVs or large glass). Moreover, if the volume of the machine is further enlarged to produce a larger piece of air column to increase the accommodation space, the cost and the space occupied by the machine are greatly increased, which is not economical.

In view of the above problems, the present invention provides a buffer air bag comprising a first air column piece, a second air column piece, a common transverse heat sealing line, a neck heat sealing line and a common inflation channel.

The pressure entering the passage 32 is relatively large, so that the gas entering the first air column 19 and the second air column 29 is not easily escaped to achieve the effect of locking the air.

Furthermore, the lengths of the two first intermediate film 13, the second intermediate film 23, the first inner film 12 and the second inner film 22 beyond the neck heat seal line 31 and located in the common inflation channel 32 are slightly exceeded. The neck heat seal line 31 is preferred. However, it is not limited thereto, as long as the portion beyond the neck heat seal line 31 does not sag or oscillate to shield the first intake port 131 from the second intake port 231.

In summary, the buffer air bag 1 can form two air column pieces (ie, the first air column piece 10 and the second air column piece 20) which are superposed on each other and are connected to each other in one heat sealing process, and are not A buffer air bag 1 capable of covering a larger article can be made by enlarging the size of the machine. That is to say, the heat sealing structure of the conventional gas packaging bag can only form a single piece of air column and must be bent to cover the article, and the buffer air bag 1 of the present invention has two air column pieces that are connected to each other and can be The article is wrapped in the case of bending, or can be further expanded to form a larger covering space, which is further illustrated as follows:

As shown in FIG. 7, the user can directly place a large article (such as a liquid crystal television) between the first air column piece 10 and the second air column piece 20 to form a coating effect, compared to a conventional gas packaging bag. In other words, the present invention can be formed without a need to bend to form a covering space, and thus can have a larger covering area. Or, as shown in FIG. 8, the first air column piece 10 and the second air column piece 20 may also be pivotally pivoted to one side on the same plane to further expand the space for covering the article. Then, the covering space can be formed by bending to package the article. In the present embodiment, the buffer air bag 1 is folded into a U-shaped shape after being unfolded, but is not limited thereto, and may be bent into a W shape or other irregular shape according to the actual article shape.

As shown in FIG. 5, in the present embodiment, the edges of the first inner film 12 and the second inner film 22 in the common inflation channel 32 are respectively aligned with the edges of the first intermediate film 13 and the second intermediate film 23, It can be synchronized during the inflation process. However, the present invention is not limited thereto. In other aspects, the edge of the first inner film 12 and the second inner film 22 in the common inflation channel 32 may also be shorter or longer than the first intermediate film 13 and the second. The edge of the intermediate film 23.

As shown in FIG. 6, in the present embodiment, the lengths of the first inner film 12 and the second inner film 22 of the buffer air bag 1A are equal to the lengths of the first outer film 11 and the second outer film 21, and the first The region of the inner film 12 and the second inner film 22 in the common inflation channel 32 is provided with one or a plurality of spaced-apart perforations 34, which may be round holes, elongated holes or other irregular holes, and are common The transverse heat seal line 30 further follows the first inner film 12 and the second inner film 22. Thereby, it is possible to increase the bonding strength of the cushion air bag 1 (because the edges of the first inner film 12, the second inner film 22, the first outer film 11 and the second outer film 21 are heat-sealed), and when they are inflated together When the passage 32 is filled with gas by the inflation port 33, the gas can be filled through the perforations 34 so that the gas can be filled and the entire common inflation passage 32 can be expanded.

In addition, the buffer air bag 1 further includes a plurality of heat sealing portions 36 located in the first air column 19 and the second air column 29, and the heat sealing portion 36 is followed by two first intermediate films 13 and two second intermediate films 23, respectively. Each heat seal portion 36 includes at least one heat seal point 361, at least one heat seal line 362, or a combination thereof, and the heat seal line 362 may be a straight line, a diagonal line, an arc line, or an irregular line. As shown in Fig. 9, the heat seal portion 36 of the buffer air bag 1B is formed by a heat-sealed line 362 which is alternately arranged in a staggered manner, so that after the gas enters the first gas column 19 and the second gas column 29, Since the layers of the plurality of heat seal lines 362 are blocked and are not easily recirculated, the sealing effect and the buffering function of the first air column 19 and the second air column 29 are ensured, and the service life of the buffer air bag 1 is prolonged.

Alternatively, as shown in FIG. 10, the heat seal portion 36 of the buffer air bag 1C is composed of a heat seal point 361 and a second heat seal line 362, and the two heat seal lines 362 are spaced apart, and the heat seal line 362 is provided. The intermediate portion is more outwardly convex to form an enlarged region, and the heat seal point 361 is located in the enlarged region. Thereby, the pressure in the enlarged region is greater than the pressure on both sides, so that the gas entering the first gas column 19 and the second gas column 29 is not easily escaped to achieve the effect of locking the gas.

Although the technical content of the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the present invention, and any modifications and refinements made by those skilled in the art without departing from the spirit of the present invention are encompassed by the present invention.
