Description

緩衝氣袋Buffer air bag

本發明係關於一種包裝袋結構,特別是指一種緩衝氣袋結構。The present invention relates to a package structure, and more particularly to a cushion air bag structure.

一般物品需要搬運或寄送時,大多都會進行包裝作業,為了避免物品在運送過程中產生碰撞損毀,目前都是利用氣泡紙或保麗龍包覆保護。然而在實際使用經驗中,氣泡紙與保麗龍仍有緩衝效果不佳而容易導致物品損壞之問題。有鑑於上述問題,便發展出一種氣體包裝袋,其經由熱封形成氣柱,以供充入氣體而使氣體包裝袋能夠具有緩衝作用。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.

上述複數第一氣閥15是連通於共同充氣通道32與複數第一氣柱19,複數第二氣閥25連通於共同充氣通道32與複數第二氣柱29。於本實施例中,第一耐熱材料14為長條狀且其塗佈範圍是延伸至第一中間膜13位於共同充氣通道32中的邊緣以及第一中間膜13位於第一氣柱19中的區域,使複數第一氣閥15連通於共同充氣通道32與複數第一氣柱19而形成氣體通道,且令各第一氣閥15形成位於共同充氣通道32中之第一進氣口131。第二耐熱材料24同樣為長條狀且其塗佈範圍是延伸至第二中間膜23位於共同充氣通道32的邊緣以及第二中間膜23位於第二氣柱29中的區域。使複數第二氣閥25連通於共同充氣通道32與第二氣柱29而形成氣體通道,且令各第二氣閥25形成位於共同充氣通道32中之一第二進氣口231。但本發明並不以此為限,於一些態樣中,第一耐熱材料14與第二耐熱材料24也可與第一中間膜13與第二中間膜23等長。或者亦可在二第一中間膜13之間以及二第二中間膜23之間預設有隔熱片以取代第一耐熱材料14與第二耐熱材料24,且隔熱片的長度實質上可相同於二第一中間膜13與二第二中間膜23的寬度,或者隔熱片的寬度小於二第一中間膜13與二第二中間膜23的寬度且間隔排列設置於二第一中間膜13之間以及二第二中間膜23之間。The plurality of first air valves 15 are connected to the common inflation passage 32 and the plurality of first air columns 19, and the plurality of second air valves 25 are in communication with the common inflation passage 32 and the plurality of second air columns 29. In the present embodiment, the first heat-resistant material 14 is elongated and its coating range is extended to the edge of the first intermediate film 13 in the common inflation channel 32 and the first intermediate film 13 is located in the first gas column 19. In the region, the plurality of first air valves 15 are communicated with the common inflation passage 32 and the plurality of first air columns 19 to form a gas passage, and each of the first gas valves 15 forms a first intake port 131 located in the common inflation passage 32. The second heat-resistant material 24 is also elongated and has a coating range extending to a region where the second intermediate film 23 is located at the edge of the common inflation passage 32 and the second intermediate film 23 is located in the second gas column 29. The plurality of second air valves 25 are communicated with the common inflation passage 32 and the second air column 29 to form a gas passage, and each of the second air valves 25 is formed to be located at one of the second intake ports 231 of the common inflation passage 32. However, the present invention is not limited thereto. In some aspects, the first heat resistant material 14 and the second heat resistant material 24 may be equal in length to the first intermediate film 13 and the second intermediate film 23. Alternatively, a heat insulating sheet may be disposed between the two first intermediate films 13 and between the two second intermediate films 23 to replace the first heat resistant material 14 and the second heat resistant material 24, and the length of the heat insulating sheet is substantially The width of the two first intermediate film 13 and the second second intermediate film 23 is the same, or the width of the heat insulating sheet is smaller than the width of the two first intermediate film 13 and the second second intermediate film 23 and is arranged at intervals in the two first intermediate films. Between 13 and between the second intermediate film 23.

藉由上述結構設計,當共同充氣通道32由充氣口33充入氣體時,藉由第一內側膜12與第二內側膜22的長度小於第一外側膜11與第二外側膜21的長度,使第一內側膜12接著於第一中間膜13的側邊與第二內側膜22接著於第二中間膜23的側邊是位於共同充氣通道32中,因此氣體不會受到阻隔而能夠充滿整個共同充氣通道32產生膨脹,構成第一外側膜11與第二外側膜21由平面狀態膨脹成具有弧度之立體狀態,而可透過複數第一熱封點16與複數第二熱封點26分別將第一中間膜13與第二中間膜23拉開而分別開啟複數第一進氣口131與複數第二進氣口231。也就是說,由於熱封點是接著於第一外側膜11與其中一個第一中間膜13以及第二外側膜21與其中一個第二中間膜23,因此,當第一外側膜11與第二外側膜21膨脹成具有弧度之立體狀態,也會同步帶動第一中間膜13與第二中間膜23而開啟複數第一進氣口131與複數第二進氣口231,使複數第一氣閥15能夠引導氣體充入複數第一氣柱19,複數第二氣閥25能夠引導氣體充入複數第二氣柱29,使複數第一氣柱19與複數第二氣柱29膨脹而能夠在包覆物品時具有緩衝的效果。此外,當複數第一氣柱19與複數第二氣柱29充氣膨脹後,第一氣柱19與第二氣柱29會因內部壓力而壓迫密合二第一中間膜13與二第二中間膜23,進而封閉第一氣閥15與第一氣柱19、第二氣閥25與第二氣柱29,達到防止氣體外洩的效果。With the above structural design, when the common inflation passage 32 is filled with the gas by the inflation port 33, the length of the first inner film 12 and the second inner film 22 is smaller than the lengths of the first outer film 11 and the second outer film 21, Having the first inner film 12 next to the side of the first intermediate film 13 and the second inner film 22 followed by the side of the second intermediate film 23 is located in the common inflation channel 32, so that the gas is not blocked and can be filled throughout The common inflation passage 32 is expanded to constitute a first outer membrane 11 and a second outer membrane 21 which are expanded from a planar state to a three-dimensional state having a curvature, and the first plurality of heat seal points 16 and the plurality of second heat seal points 26 are respectively The first intermediate film 13 and the second intermediate film 23 are pulled apart to open the plurality of first air inlets 131 and the plurality of second air inlets 231, respectively. That is, since the heat sealing point is followed by the first outer film 11 and one of the first intermediate film 13 and the second outer film 21 and one of the second intermediate films 23, when the first outer film 11 and the second film The outer film 21 is expanded into a three-dimensional state having a curvature, and the first intermediate film 13 and the second intermediate film 23 are simultaneously driven to open the plurality of first air inlets 131 and the plurality of second air inlets 231, so that the plurality of first air valves 15 can guide the gas to be charged into the plurality of first gas columns 19, and the plurality of second gas valves 25 can guide the gas to be charged into the plurality of second gas columns 29, and expand the plurality of first gas columns 19 and the plurality of second gas columns 29 to be packaged. It has a cushioning effect when covering items. In addition, when the plurality of first air columns 19 and the plurality of second air columns 29 are inflated, the first air column 19 and the second air column 29 are pressed against the first intermediate film 13 and the second intermediate portion by internal pressure. The membrane 23 further encloses the first air valve 15 and the first air column 19, the second air valve 25, and the second air column 29 to achieve an effect of preventing gas leakage.

此外,於本實施例中,第一氣閥15與第二氣閥25位於共同充氣通道32一端的寬度是大於位於第一氣柱19與第二氣柱29一端之寬度,使氣體由共同充氣通道32進入的壓力較大,而令進入第一氣柱19與第二氣柱29的氣體不易逸出而達到鎖氣的效果。In addition, in the present embodiment, the width of the first gas valve 15 and the second gas valve 25 at one end of the common gas passage 32 is greater than the width of one end of the first gas column 19 and the second gas column 29, so that the gas is co-inflated. 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.

再者,上述二第一中間膜13、二第二中間膜23、第一內側膜12及第二內側膜22超出頸部熱封線31且位於共同充氣通道32中的長度,是以略超出頸部熱封線31為較佳。但並不侷限於此,只要超出頸部熱封線31的部分不會因下垂或擺動而遮蔽第一進氣口131與第二進氣口231的即可。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.

綜上所述,緩衝氣袋1可在一次熱封加工過程中形成相互疊合且一側相互銜接的二氣柱片(即第一氣柱片10與第二氣柱片20),達到不須擴大機台體積就可製成能夠包覆更大型的物品之緩衝氣袋1。也就是說,習知氣體包裝袋的熱封結構僅能形成單一片氣柱而必須再經過彎折才能包覆物品,而本發明緩衝氣袋1具有相互銜接的二氣柱片而能夠在不彎折的情況下包覆物品,或者能夠進一步展開形成更大的包覆空間,此進一步配合圖式說明如下: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:

如第7圖所示,使用者可將大型物品(如液晶電視)直接置於第一氣柱片10與第二氣柱片20之間而形成包覆作用,相較於習知氣體包裝袋來說,本發明可不須再彎折形成包覆空間,因此能夠具有更大的包覆面積。或者如第8圖所示,第一氣柱片10與第二氣柱片20也可以其相互銜接的一側為樞轉點旋擺展開而位於同一平面上,以進一步擴大包覆物品的空間,接著可透過彎折的方式形成包覆空間以供包裝物品。於本實施例中,緩衝氣袋1展開後是折成U型態樣,但並不侷限於此,亦可依據實際物品形狀彎折成W形或其他不規則形。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.

如第5圖所示,於本實施例中,第一內側膜12與第二內側膜22位於共同充氣通道32中的邊緣是分別對齊第一中間膜13與第二中間膜23的邊緣,以在充氣的過程中能夠同步作動。但本發明並不以此為限,於另一些態樣中,第一內側膜12與第二內側膜22位於共同充氣通道32中的邊緣也可短於或長於第一中間膜13與第二中間膜23的邊緣。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.

如第6圖所示,於本實施例中,緩衝氣袋1A的第一內側膜12與第二內側膜22的長度是等於第一外側膜11與第二外側膜21的長度,且第一內側膜12與第二內側膜22位於共同充氣通道32中的區域開設有一個或複數個間隔配置的穿孔34,所述穿孔34可為圓孔、長形孔或其他不規則形孔,且共同橫熱封線30更接著第一內側膜12與第二內側膜22。藉此,能夠達到增加緩衝氣袋1的結合強度(因第一內側膜12、第二內側膜22、第一外側膜11及第二外側膜21的邊緣皆熱封結合),且當共同充氣通道32由充氣口33充入氣體時,也可透過穿孔34使氣體不會受到阻隔而能夠充滿整個共同充氣通道32產生膨脹。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.

另外,緩衝氣袋1更包括複數個熱封部36,位於第一氣柱19與第二氣柱29中,所述熱封部36分別接著二第一中間膜13與二第二中間膜23,各熱封部36包括至少一熱封點361、至少一熱封線362或其組合,所述熱封線362可為直線、斜線、弧線或不規則線。如第9圖所示,緩衝氣袋1B的熱封部36為間隔交錯且概呈弧形的熱封線362所構成,使氣體在進入第一氣柱19與第二氣柱29後,會因為複數熱封線362的層層阻擋而不易回流,以確保第一氣柱19與第二氣柱29的封閉效果與緩衝功能,延長緩衝氣袋1的使用壽命。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.

或者,如第10圖所示,緩衝氣袋1C的熱封部36是由熱封點361與二熱封線362所構成,所述二熱封線362為間隔配置,且二熱封線362的中間區域更相對向外凸出而形成擴大區域,而熱封點361是位於擴大區域中。藉此,擴大區域中壓力會大於兩側的壓力,使進入第一氣柱19與第二氣柱29的氣體不易逸出而達到鎖氣的效果。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.
