Abstract
Description
本發明是關於一種密封體結構，特別是指一種用以對包裝物提供緩衝及防震作用，並可快速開啟入氣口及有效量產之空氣密體結構。The invention relates to a sealing body structure, in particular to an air dense structure for providing buffering and shockproof effects on a package, and capable of quickly opening an air inlet and effectively mass-producing.
傳統包裝材為保護包裝物而在周圍加設一軟質內墊（如泡棉），可避免內裝物因外部震動而造成損壞或破裂。然而，該軟質內墊需另行加工縫製於包裝材，以防止其移動或脫落於包裝材，惟加工過程不僅繁瑣，軟質內墊之製備更大幅增加包裝材之製造成本。
有鑒於前述缺點，一種充氣結構係經研發作為緩衝外力之構造，利用空氣填充形成氣柱，可有效保護物體，避免震晃動，習知快速開啟入氣口之空氣密封體如中華民國發明專利第587049號專利，其中該空氣密封體具有二袋片材及二閥片材設於該二袋片材內接著形成，並於內形成一開關閥之通路及一空氣導入通道，當充氣後，密封體膨脹以阻斷通路，惟此開關閥只描述如何將密封體的空氣阻斷不洩出，但當空氣導入通道充入氣體而膨脹，即使二袋片材受氣體推擠而向外拉開，開關閥並不會隨著二袋片材作動而向外漲開，因此開關閥之二閥片材仍貼附一起而無法開啟空氣通路入口，則空氣無法自動進入密封體；此外，該內部之二閥片材需單獨設於外層之片材，增加製造流程，且由於二外袋片材和內部二閥片無法同時生產製造，嚴重阻礙充氣結構之量產效率，無形中增加製造成本。又美國專利US7568508號提示二外膜內夾二內膜，二內膜在預定點設複數耐熱材料並施予熱封點及熱封線，形成充氣道，充氣後會將二片內膜各別併同各該相對應的外膜，膨脹面拉開入氣口，使空氣流入氣口進入氣柱，本專利的缺點:為二內膜必低於二外膜，其熱封點若有偏移，在充氣時二內膜會反折將入氣口遮住無法入氣。
緣是，如何改良一種充氣結構，使其製作工序簡化，並能自動快速開啟入氣口並連續充氣不會發生內膜充氣蓋住入氣口，又可於閉氣後自動止氣逆流，且二外部片材及二內部片材能同時裁切製作，無須單獨之接著過程，乃業界亟需克服之課題。The traditional packaging material is provided with a soft inner pad (such as foam) around the protective packaging material to prevent the internal contents from being damaged or broken due to external vibration. However, the soft inner pad needs to be separately processed and sewed into the packaging material to prevent it from moving or falling off the packaging material, but the processing process is not only cumbersome, but the preparation of the soft inner cushion further increases the manufacturing cost of the packaging material.
In view of the foregoing shortcomings, an inflatable structure is developed as a buffer external force structure, which is filled with air to form a gas column, which can effectively protect an object and avoid shaking, and an air sealing body which is quick to open the air inlet is, for example, the Republic of China invention patent No. 587049 No. Patent, wherein the air sealing body has two bag sheets and two valve sheets are formed in the two bag sheets, and a passage of an on-off valve and an air introduction passage are formed therein, and when inflated, the sealing body Expanding to block the passage, but the on-off valve only describes how to block the air of the sealing body from leaking, but when the air introduction passage is filled with gas to expand, even if the two bags of sheets are pushed by the gas and pulled outward, The on-off valve does not open outwards as the two-bag sheet is actuated, so that the two valve sheets of the on-off valve are still attached together and cannot open the air passage inlet, the air cannot automatically enter the sealing body; The two-valve sheet needs to be separately disposed on the outer sheet to increase the manufacturing process, and since the two outer bag sheets and the inner two-valve sheet cannot be simultaneously manufactured, the mass production effect of the inflatable structure is seriously hindered. , Potentially increasing manufacturing costs. U.S. Patent No. 7,568,508 indicates that the inner membrane is sandwiched between the two outer membranes, and the second inner membrane is provided with a plurality of heat-resistant materials at a predetermined point and a heat sealing point and a heat sealing line are applied to form an inflation channel, and the two inner membranes are separated after inflation. Corresponding to each of the outer membranes, the expansion surface is pulled into the air inlet to allow air to flow into the air inlet into the air column. The disadvantage of this patent is that the inner membrane must be lower than the outer membrane, and if the heat sealing point is offset, When inflated, the inner membrane will fold back and the air inlet will be blocked from entering the air.
The reason is how to improve an inflatable structure, so that the manufacturing process is simplified, and the air inlet can be automatically opened quickly and continuously inflated without intima filling to cover the air inlet, and the air can be automatically stopped after the air is closed, and the outer piece is The material and the two internal sheets can be cut at the same time, without a separate process, which is an urgent problem to be overcome in the industry.

當氣體由該充氣道之至少一充氣端充入，氣流經由該複數導氣孔貫入並撐開該二外膜及二內膜，使該導氣部膨漲形成一引流道位於該二內之間，該引流道和該第一熱封線交錯處形成一入氣口，使氣體快速從該入氣口注入充滿該複數氣柱，並於該複數氣柱內產生壓力壓迫該二內膜緊靠貼附，以防止氣體外洩出該引流道。
依據本發明之一實施例，每一內膜相對該複數導氣部和該內膜之頂緣之間設有複數導氣孔，該複數導氣孔連通該些引流道和氣柱，當該充氣道充氣後，氣流經由該複數導氣孔貫入並撐開該二內膜，且進入該些引流道至該複數氣柱。
依據本發明之另一實施例，每一導氣部對應該充氣道處設有相互間隔排列之若干切線，該充氣道於充氣後，氣體經由該些切線進入該引流道至該氣柱。

依據本發明之另一實施例，每一第二熱封線具有至少一缺口，使該複數氣柱之間可相互連通並共用複數入氣口。
本發明快速開啟入氣口之空氣密封體利用二內膜之頂緣延伸至二外膜之上緣，以利內膜製造時之定位作業，並可和外膜同時進行裁切並熱封接著，此外，設置複數導氣孔，從充氣道的任一充氣口皆可充氣，充氣後因充氣道內的二內膜預設有複數導氣孔及耐熱材料在充氣道部設有熱封塊，使二內膜、二外膜於充氣道充氣時各膜面空氣可互相引流，但受限於外膜與內膜已先熱封固接，故只能形成以同一側內外膜的方向與另一側內外膜的方向拉開，空氣自然開啟入氣口進入各氣柱內。且二內膜可自動封閉止氣逆流外洩。而導氣孔及切線結構可提供任一位於充氣道內之位置充氣。是以，本發明快速開啟入氣口之空氣密封體能快速充氣，有效簡化內外膜之製造及接著工序，降低製造成本，並可大幅提升量產效率。An object of the present invention is to provide an air sealing body which can simplify the manufacturing process and improve the mass production efficiency and quickly open the air inlet.

本發明之快速開啟入氣口之空氣密封體利用空氣快速填充形成一緩衝防震構造，其可自動開啟引流道，並於充氣後自動閉鎖引流道，該快速開啟入氣口之空氣密封體可為單一排柱狀，或可經彎曲形成一容置空間，用以對物品提供緩衝防震構造。
請參閱第一圖至第三圖為本發明之空氣密封體1之較佳實施例之一，於此實施例中，本發明之空氣密封體1為單一排柱狀，其包括二外膜2a，2b及二內膜3a，3b，其可分別為透明或不透明狀，二外膜2a，2b相對應設置並具有相同之大小，其周圍分別設有一熱封邊20，藉熱封手段接著一體。一第一熱封線21設於二外膜2a，2b上，用以將二外膜2a，2b分隔成一充氣道4及一緩衝部5。該二內膜3a，3b藉第一熱封線21熱封接著於二外膜2a，2b內，使二內膜3a，3b之一部份位於充氣道4內，另一部分位於緩衝部5內。於此實施例中，二內膜3a，3b之厚度分別小於二外膜2a，2b。
充氣道4形成於二外膜2a，2b之上緣2c和第一熱封線21之間，且其一端設有至少一充氣口41，以供充氣之用，於此實施中，二外膜2a，2b和二內膜3a，3b之間分別形成一充氣口41。本案充氣方式可利用外部空氣壓縮機(未圖示)連接氣針(未圖示)插入充氣口41進行快速充氣。緩衝部5上設有複數第二熱封線22，藉複數第二熱封線22熱封形成複數氣柱51，該些第二熱封線22分別垂直並延伸至第一熱封線21，使複數氣柱51和充氣道4呈不同方向設置，以強化充氣結構1之結構強度。複數氣柱51相鄰成行排列。於另一較佳實施中，每一第二熱封線22具有至少一缺口221，使該複數氣柱51之間可相互連通並共用複數該入氣口321。
續請參閱第二圖及第三圖，二內膜3a，3b相互面對設置，並分別延第一熱封線21延伸至二外膜2a，2b之相對二側及上緣2c，其中二內膜3a，3b之頂緣3c和二外膜2a，2b之上緣2c一體熱封接著。特別說明的是，於此實施例中，該二內膜3a，3b之內表面設有複數導氣部31，其相應該複數氣柱51設置，每一導氣部31由相應之氣柱51穿越該第一熱封線21至充氣道4內，並完全塗佈有一耐熱材料，換言之，每一導氣部31之一部分位於充氣道4內，另一部分位於氣柱51內。該複數導氣部31因塗佈有耐熱材料，不受第一熱封線21之熱封影響，因此不會接著於另一內膜3b。此外，內膜3a位於充氣道4之導氣部31和外膜2a，2b之上緣2c保持一距離，用以減少耐熱材料之使用，達到降低生產成本之功效，惟並不以此為限。於另一實施例中，位於充氣道4之導氣部31亦可延伸至外膜2a，2b之上緣2c。值得一提的是，本案二內膜3a，3b之長軸向長度延伸至二外膜2a，2b之二側以形成整片配置，且內膜3a，3b之頂緣3c延伸至外膜2a，2b之上緣2c，其有利於和外膜接著之製作過程，換言之，內膜和外膜可同時熱封接著，而非分拆成二片單獨接著後再熱封一體，且於內外膜製作時，內膜3a，3b和外膜2a，2b可成片反向相對設置，經由同時裁切即可同時分割出兩片相同之內膜和外膜，有效簡化工序，而非單片內膜單獨裁切製作。
請參閱第二及三圖，每一內膜3a，3b相對複數導氣部31和該二內膜3a，3b之頂緣3c之間設有複數導氣孔311，其連通該些導氣部31。每一導氣孔311具有相同之構形，如圓形或其形狀，或各為不同構形。考量生產製作效率，複數導氣孔311係相對應形成一排直線間隔並列。請參閱本發明第四圖，於另一實施例中，導氣部31之複數導氣孔311可改為切線312構型，該切線312結構於充氣時形成複數開口，可允許氣體流通，其作用相同於導氣孔311，該些切線312係可對應成單排橫線或多排排列
請參閱第五圖為本發明之側向剖面示意圖，本發明快速開啟入氣口之空氣密封體1充氣時，充氣氣針插入充氣口41內，氣體由充氣口41進入充氣道4，值得注意的是，無論氣針是插入於充氣道4內任一處，如任一內膜3a，3b和外膜2a，2b之間，或是插入二內膜3a，3b之間，則充氣氣體皆會流經二內膜3a，3b之複數導氣孔311進入複數導氣部31內，並撐開位於充氣道4內之二內膜3a，3b，進而造成導氣部31和相應之另一內膜3b漲開形成一引流道32，該引流道32和第一熱封線21交錯處形成一入氣口321，使氣體快速從引流道32經由該入氣口321注入充滿緩衝部5之各氣柱51，同時將二片外膜2a，2b於縱向上向外漲開形成充氣之複數氣柱51；此時，氣柱51內之二內膜3a，3b因內部壓力壓迫而相互緊靠貼附一起，進而封閉引流道32之入氣口321使氣體不逆流外洩出氣柱51，達到止氣封閉效果。
此外，每一氣柱51內亦可設有相互間隔排列之若干引流道32，其數量視氣柱51之寬度而定，用以加快氣流流通。
特別說明的是，本發明快速開啟入氣口之空氣密封體1之每一內膜3a，3b和每一外膜2b，2b之間設有複數熱封塊23 (如第三圖至第五圖所示)，其間隔排列，使二內膜3a，3b藉熱封塊23熱封定著於二外膜2a，2b於之充氣道4內，如是，充氣道4內之外膜2a與內膜3a之部分接著一體，外膜2b與內膜3a之部分接著一體，充氣時二內膜3a，3b較易自然分開，而充氣氣流直接流入引流道32內。熱封塊23之設置可以克服4片外膜及內膜到頂產生多充氣口41造成充氣位置不一的困擾。於另一實施例中，內膜3a之塗佈有耐熱材料之複數導氣部31係延伸至二外膜2a，2b之上緣2c，以提供較大面積之引流道32，加快充氣時間。
續請參閱本發明第二圖，其中面對複數導氣部31之外膜2a與內膜3a之部分設有複數引流熱封線313，其分別位於複數氣柱51內，用以先行熱封接著於相鄰之外膜2a與內膜3a，使內膜與外膜於充氣後容易密接於該外膜2a，達到閉氣效果。複數引流熱封線313可以不同構形排列。於一較佳實施中，該引流熱封線313為相對稱之曲線(如第二圖所示)，用以形成一曲線狀之氣體通道，其一端口連通於該入氣口，並具有一寬度大於另一端口，使該曲線狀內之氣體通道的壓力大於二側之氣體壓力，以加快氣流通往各氣柱內。
綜上所述，本發明之快速開啟入氣口之空氣密封體1利用二內膜3a，3b之頂緣3c延伸至二外膜2a，2b之上緣2c，以利內膜製造時之定位作業，並可和外膜2a，2b同時進行裁切並熱封接著，有效提升生產效率。此外，複數導氣孔311之設置可提供快速充氣過程，並可提供任一位於充氣道內之位置充氣，據此，本發明快速開啟入氣口之空氣密封體1能快速進行充氣，有效簡化內外膜之製造及接著工序，降低製造成本，並可大幅提升量產效率。再者，從充氣道的任一充氣口皆可充氣，充氣後因充氣道內的二內膜預設有複數導氣孔及耐熱材料在充氣道部設有熱封塊，使二內膜、二外膜於充氣道充氣時各膜面空氣可互相引流，但受限於外膜與內膜已先熱封固接，故只能形成以同一側內外膜的方向與另一側內外膜的方向拉開，空氣自然開啟入氣口進入各氣柱內。
上述詳細說明為針對本發明一種較佳之可行實施例說明而已，惟該實施例並非用以限定本發明之申請專利範圍，凡其它未脫離本發明所揭示之技藝精神下所完成之均等變化與修飾變更，均應包含於本發明所涵蓋之專利範圍中。The air sealing body of the quick opening air inlet of the invention is quickly filled with air to form a cushioning shockproof structure, which can automatically open the drainage channel and automatically lock the drainage channel after inflation, and the air sealing body of the quick opening air inlet can be a single row The columnar shape may be curved to form an accommodating space for providing a cushioning and shockproof structure for the article.

The first heat seal line 21 is passed through the first heat seal line 21 and is completely coated with a heat resistant material. In other words, one portion of each air guide portion 31 is located inside the air passage 4 and the other portion is located inside the air column 51. Since the plurality of air guide portions 31 are coated with the heat resistant material and are not affected by the heat seal of the first heat seal line 21, they do not follow the other inner film 3b. In addition, the inner membrane 3a is located at the air guiding portion 31 of the inflation channel 4 and the outer film 2a, and the upper edge 2c of the 2b is kept at a distance for reducing the use of the heat-resistant material to reduce the production cost, but not limited thereto. .

During production, the inner membranes 3a, 3b and the outer membranes 2a, 2b can be arranged in opposite directions in a sheet, and two identical inner and outer membranes can be simultaneously divided by simultaneous cutting, thereby simplifying the process rather than in a single piece. The film is cut separately.
Referring to the second and third figures, each of the inner membranes 3a, 3b is provided with a plurality of air guiding holes 311 between the plurality of air guiding portions 31 and the top edges 3c of the two inner films 3a, 3b, which communicate with the air guiding portions 31. .

Considering the production efficiency, the plurality of air guiding holes 311 are formed in a row and arranged in parallel. Referring to the fourth embodiment of the present invention, in another embodiment, the plurality of air guiding holes 311 of the air guiding portion 31 can be changed to a tangential line 312 configuration, and the tangential line 312 is configured to form a plurality of openings during inflation to allow gas to circulate. The same as the air guiding hole 311, the tangential lines 312 can be arranged in a single row of horizontal lines or a plurality of rows. Please refer to the fifth drawing for a side cross-sectional view of the present invention. When the air sealing body 1 of the present invention rapidly opens the air inlet, The inflation gas needle is inserted into the inflation port 41, and the gas enters the inflation channel 4 from the inflation port 41. It is noted that the gas needle is inserted anywhere in the inflation channel 4, such as any of the inner membranes 3a, 3b and the outer membrane 2a. Between 2b, or between the two inner membranes 3a, 3b, the inflation gas will flow through the inner membranes 3a, 3b, and the plurality of air guiding holes 311 enter the plurality of air guiding portions 31, and are opened at the inflation channel 4 The inner inner membranes 3a, 3b further cause the air guiding portion 31 and the corresponding inner inner membrane 3b to open to form a drainage channel 32, and the air guiding channel 32 and the first heat sealing line 21 are alternately formed with an air inlet 321 The gas is quickly injected from the drain channel 32 through the gas inlet 321 into the gas column filled with the buffer portion 5 51, at the same time, the two outer membranes 2a, 2b are raised outward in the longitudinal direction to form a plurality of inflated air columns 51; at this time, the inner membranes 3a, 3b in the air column 51 are closely attached to each other due to internal pressure compression. Together, the air inlet 321 of the drain passage 32 is closed to allow the gas to flow out of the gas column 51 without backflow, thereby achieving a gas-tight sealing effect.
In addition, each of the air columns 51 may also be provided with a plurality of drainage channels 32 spaced apart from each other, the number of which depends on the width of the air column 51 for accelerating the airflow.
Specifically, a plurality of heat seal blocks 23 are disposed between each of the inner membranes 3a, 3b and each of the outer membranes 2b, 2b of the air seal body 1 of the present invention for rapid opening (as shown in the third to fifth figures). As shown, the spacers are arranged such that the inner membranes 3a, 3b are heat-sealed by the heat seal block 23 in the second outer membrane 2a, 2b in the inflation channel 4, for example, the outer membrane 2a and the inner membrane 4 A portion of the membrane 3a is integrally formed, and the outer membrane 2b is integrally formed with a portion of the inner membrane 3a. When inflated, the inner membranes 3a, 3b are more naturally separated, and the inflated gas stream directly flows into the drainage channel 32. The heat seal block 23 can be arranged to overcome the problem that the four outer membranes and the inner membrane to the top of the multi-inflation port 41 cause different inflation positions. In another embodiment, the plurality of air guiding portions 31 of the inner film 3a coated with the heat resistant material extend to the upper edges 2c of the second outer film 2a, 2b to provide a larger area of the drainage channel 32 to accelerate the inflation time.
Referring to the second drawing of the present invention, a portion of the outer membrane 2a and the inner membrane 3a facing the plurality of air guiding portions 31 is provided with a plurality of drainage heat sealing lines 313 respectively located in the plurality of air columns 51 for heat sealing first. Next, adjacent to the outer membrane 2a and the inner membrane 3a, the inner membrane and the outer membrane are easily intimately adhered to the outer membrane 2a after inflation, thereby achieving a gas-closing effect. The plurality of drainage heat seal lines 313 can be arranged in different configurations. In a preferred embodiment, the drainage heat seal line 313 is a symmetrical curve (as shown in the second figure) for forming a curved gas passage, a port of which is connected to the air inlet and has a width. More than the other port, the pressure of the gas passage in the curve is greater than the pressure of the gas on both sides to accelerate the flow of air into the respective gas columns.
In summary, the air sealing body 1 of the quick opening air inlet of the present invention extends to the upper edge 2c of the second outer film 2a, 2b by the top edge 3c of the inner film 3a, 3b, so as to facilitate the positioning operation during the manufacture of the inner film. And can be cut and heat sealed simultaneously with the outer film 2a, 2b, thereby effectively improving production efficiency. In addition, the plurality of air guiding holes 311 are provided to provide a rapid inflation process, and can be provided at any position in the inflation channel.
