In order to form the pocket portion 155 that has opening, use two pocket portion thin slice 159A shown in Fig. 7 A and the 7B and 159B.These two pocket portion thin slice 159A are connected thereon at the roughly midway location of enclosure portion 199 with 159B.Fig. 8 A is a planar view, and it shows the flat sheet of enclosure portion 199.The end of pocket portion thin slice 159A and 159B (engaging zones 301) can be bonded together as shown in Fig. 8 B, so that be connected in enclosure portion 199.Perhaps, the parting seal (engaging zones) 271 of enclosure portion 199 can be separated and be connected at different vertical height place to each thin slice 159 as shown in Fig. 8 C.The side end 301 of pocket portion 155 (pocket sheet 159) is connected in engaging zones (parting seal) 271 at the side part 171 and 175 places of enclosure portion usually.
Although more than described the preferred embodiments of the present invention, multiple other modification can be arranged according to the present invention.Fig. 9 and 10 is transparents view, and it shows other embodiment of air-packing device 201 of the present invention.With reference to Fig. 9, show alternative embodiment, wherein the end of pocket portion 155 is at the inferior hermetic unit that is connected in enclosure portion 199 of difference row.As shown in the figure, the opening of pocket portion 155 is greater than the opening of the air-packing device 201 shown in Fig. 3 B-3D.For example, can utilize the quantity of the air chamber of the size of an air chamber or enclosure portion 199 to increase interval between the pocket sheet.Upper strata pocket sheet 159B institute bonded assembly parting seal 271 is higher than pocket sheet 159A institute of lower floor bonded assembly parting seal 271 one or more air chambers.
Figure 10 is the transparent view of alternative embodiment of air-packing device 201 of the present invention.Except the air chamber of pocket portion 155 towards variation having taken place, the similar shown in this structure and Fig. 3 A-3F.That is to say that in Figure 10, the air chamber 101 of pocket portion thin slice 159A and 159B is towards the fore-and-aft direction shown in left and right directions rather than Fig. 3 A-3F.Although pocket portion thin slice 159A and 159B all have check valve, these check valves are all not shown in Figure 10.
Figure 11 A-11C illustrates in greater detail the example in the structure of the check valve of being realized in the present invention.In Figure 11 A-11C, check valve is by Reference numeral 44 expressions and be equivalent to the check valve 291 shown in Fig. 3-10.Figure 11 A is the top view of check valve 44, Figure 11 B be along the X-X line among Figure 11 A obtain at the cross-sectional side view of the check valve 44 when air-packing device is supplied with pressurized air not, Figure 11 C is the cross-sectional side view of the check valve 44 of pressurized air when being supplied to air-packing device.
In the example shown in Figure 11 A and the 11B, near check valve inlet 63a, be formed with enhanced leaktightness part 72.These parts are arranged to the form that contacts with each end of air inlet parts 63a.Hermetic unit 72 is set in order to the border between reinforcement guide channel 63 and the air vessel (air chamber 42), thereby prevents that air vessel from breaking when inflation.In check valve 44 of the present invention, enhanced leaktightness part 72 is preferred and inessential, therefore can omit.
In air-packing device 201, two check valve film 92a and 92b place (stacked) side by side and are clipped between near the two air-packing film 91a and 91b and fixing seal part 71-72,65 and 67 the guide channel 63.Fixing seal part 71-72 is known as exterior section, and fixing seal part 65 is known as projection (or widening) part, and fixing seal part 67 is called as narrowed portion.These fixing seal parts have also formed the structure of check valve 44, and simultaneously check valve are fixed on the first air-packing film 91a.Fixing seal part 65 is made by check valve film 92a and 92b are only merged with the first air-packing film 91a.
Check valve 44 is made by two check valve film (thermoplastic film) 92a-92b, and air duct (passage) 78 is formed at therebetween whereby.How show air by check valve 44 by the arrow that indicates by Reference numeral 77a, 77b and 77c among Figure 10 A.Pressurized air is from leading passage 63 through air duct 78 air supply containers 42 (air chamber 42).
In check valve 44, although have fixing seal part 65,67 and 71-72, the conventional air air duct 78 of relatively easily flowing through.Yet the air that refluxes in the valve is with impassabitity air duct 78.In other words, if reflux in the air duct 78, because the pressure that refluxes and self produce, refluxing is stoped.Because this pressure, two surfaces opposite to each other of check valve film 92a and 92b form closed contact, and as shown in Figure 11 C, this point describes after a while.
As mentioned above, in Figure 11 A-11B, fixing seal part 65,67 and 71-72 also are used to guide in the inrush of air check valve 44.Fixing seal partly comprises part 71a, 72a, 65a, the 67a that two check valve film 92a and 92b are bonded together, and part 71b, 72b, 65b, 67b that the first air-packing film 91a and the first check valve film 92b are bonded together.Therefore, the air duct 78 in the check valve 44 is able to form as being formed at two passages between the check valve film 92a-92b.
In addition, in Figure 11 A, fixing seal part 67 by two along the forming to the symmetrical linear segment of projection upward of this figure, fixing seal part (narrowed portion) 67 makes the narrowed width of air duct 78.In other words, conventional fluid can easily enter air chamber 42 through air duct 78 when wide space arrives narrowed portion 67 formed narrow spaces.On the other hand, when air returned via narrowed portion 67 formed narrow spaces, narrowed portion 67 was tending towards hindering the backflow from air chamber 42.
Extended portion 65 forms in abutting connection with narrowed portion 67.The shape of extended portion 65 is similar to heart, so that air flow divert.By making air pass through extended portion 65, it is turned to, and air is along the edge mobile (shown in arrow 77b) of extended portion 65.When air flow air chamber 42 (flow forward), air flows naturally in extended portion 65.On the other hand, owing to reflux to meet with extended portion 65 and change of direction, the backflow narrowed portion 67 of can not directly flowing through.Therefore, extended portion 65 also is used to stop the backflow of air.
Exit portion 71-72 forms in abutting connection with extended portion 65.In this example, exit portion 71 is formed at the center upper portion place of check valve 44 along air-flow direction, and the edge forms symmetrically perpendicular to two exit portion 72 of the direction projection of exit portion 71.There are a plurality of spaces between these exit portion 71 and 72.These spaces constitute the part of air duct 78, and air can be along direction shown in the arrow 77c by described air duct.When air is supplied to air vessel 42 (air chamber 42), exit portion 71-72 becomes the final by part of check valve 44, and by after the exit portion 71-72, air turns to along four the tunnel.
Illustrated as above that air-flow transmitted to air chamber 42 through check valve 44 relatively reposefully from guide channel 63.And then, be formed at the backflow that check valve 44 interior narrowed portion 67, extended portion 65 and exit portion 71-72 stop air jointly.Therefore, can not pass through air duct 78 easily from the backflow of air chamber 42, this helps to carry out air fed process in air-packing device.
Figure 11 C is a viewgraph of cross-section, and it shows a kind of implementation of check valve 44 of the present invention.This example shows when air-packing device and fully expands, refluxes when attempting to produce within it, check valve 44 in-to-in situations.At first, because exit portion 71 and 72 has played the effect that stops air, air almost can not enter air duct 78, can not enter exit portion easily thereby reflux.On the contrary, in the space between the inrush of air second air-packing film 91b and the second check valve film 92a, as shown in arrow 66, described space is charged into gas, shown in Figure 11 C.By this expansion, in Figure 11 C, the second check valve film 92a is depressed into the right side, and meanwhile, the first check valve film 92b is depressed into the left side.Therefore, two check valve film 92a and 92b form closed contact, and be as shown in arrow 68.Thereby backflow is completely blocked.
12A-12D, 13-14 and 15A-15B describe another example of check valve of the present invention in detail in conjunction with the accompanying drawings, and wherein check valve is indicated by Reference numeral 85.Figure 12 A-12D is the planar view that is used for the check valve 85 in the air-packing device 201 of the present invention.Figure 12 A shows a kind of structure of check valve 85 and the part of air-packing device 201.Air-packing device 201 with check valve 85 is made up of the two row or multi-row air vessel, and each air vessel all has the air chamber 83 that serial connection links to each other, and described air chamber is equivalent to the air chamber 101 among Fig. 3-10.As mentioned above, although only show an air chamber in Figure 12 A, every emptying air-capacitor device generally includes the air chamber 83 that a plurality of serial connections link to each other.
Before air supply, air-packing device 201 is elongated rectangular sheet, and it is made by first (upper strata) thermoplastic film 93 and second (lower floor) thermoplastic film 94.In order to form this structure,, form the air chamber that each group serial connection links to each other by engaging first thermoplastic film (air-packing film), 93 and second thermoplastic film (air-packing film) 94 along parting seal (bonding land) 82.Thereby air chamber 83 is formed, and like this, the air chamber that each group serial connection links to each other can fill with air independently.
The check valve film 90 that comprises a plurality of check valves 85 be connected in thermoplastic film 93 and 94 one of them, shown in Figure 12 C.When connecting check valve film 90, remover 87 is coated in pre-position on check valve film 90 and thermoplastic film 93 and 94 parting seal 82 between one of them.Remover 87 is a kind of coating with high thermal resistance, and it stops between first and second thermoplastic films 93 and 94 and produces thermal bonding.Therefore, even applying heat so that engage first and second thermoplastic films 93 and at 94 o'clock along parting seal 82, first and second thermoplastic films 93 and 94 can be not bonding mutually at place, remover 87 positions yet.
When charging into air in air-packing device 201, remover 87 allows that also admission port 81 easily opens.Stacked together when the upper and lower film 93 and 94 that is manufactured from the same material, there are two kinds of trend that film is adhered mutually.The remover 87 that is printed on the thermoplastic film stops this adhesion.Therefore, when when air-packing device is inflated, it makes the Air Compressor nozzle be easy to insert admission port 81.
Check valve 85 of the present invention disposes shared air lead part 88 and air flow maze part 86.Air lead part 88 is as conduit, and it is allowed that air flows to from admission port 81 and respectively organizes air chamber 83.Air flow maze part 86 stops air free-flowing between the air-packing device 201 and the outside thereof, that is, it is as the brake equipment that stops air-flow, and this makes air supply with operation and is easy to carry out.For realizing this brake action, air flow maze part 86 disposes the 86a-86c of two or more wall portions (heat-sealing).Because said structure, will can be not directly or freely flow into air chamber 83 from the air of shared air lead part 88, flow into and have to be zigzag.Be formed with outlet 84 in the end of air flow maze part 86.
In the air-packing device 201 that is integrated with check valve 85 of the present invention, supply with admission port 81 to flow according to mode shown in Figure 12 B to air chamber 83 gas filed pressurized airs.Planar view shown in Figure 12 B comprises check valve 85 structures identical with Figure 12 A, also comprises dotted arrow 89, and it shows the air-flow in check valve 85 and the air chamber 83.Shown in arrow 89, from the air of check valve 85 along air-packing device 201 forwards to flowing with backward directions.Therefore, check valve 85 can be formed at any position of air-packing device 201.And then when check valve 85 was connected in the midway location of air-packing device 201 at it, it required compressed air engine to have low relatively pressure.
In Figure 12 B, when air is supplied with admission port 81 by the air compressor (not shown), air flows to outlet 84 via air lead part 88 and air flow maze part 86, also flows to next-door neighbour's air chamber 83 via air lead part 88.From export 84 air of discharging by along air-packing device 201 forwards to and the mobile air chamber 83 that charges into of backward directions (dextrad of Figure 12 B and left-hand).The air that is delivered to contiguous air chamber flows in the same manner, that is, and and towards outlet 84 and mobile towards next-door neighbour's air chamber 83.This operation continues to last air chamber 83 from first air chamber 83.In other words, air lead part 88 is allowed air or is flowed to current air chamber 83 via air flow maze part 86, perhaps flows to contiguous air chamber 83.
Figure 12 C-12D shows the enlarged drawing of check valve of the present invention, is used for explaining how to form check valve 85 on air-packing device.As mentioned above, check valve film 90 and thermoplastic film 93 or 94 one of them be connected.The example of Figure 12 C and 12D shows the situation that check valve film 90 is connected in upper strata (first) thermoplastic film 93.Thick line among the figure shows the heat-sealing (joint) between the thermoplastic film.
By utilizing temperature booster to push second (lower floor) thermoplastic film 94, check valve film 90 and first (upper strata) thermoplastic film 93 and making its joint make air-packing device of the present invention.Because every film all is to be made by thermoplastic material, when imposing heat, it will engage (fusion) together.In this example, check valve film 90 is connected in upper thermoplastic film 93, and subsequently, check valve film 90 and upper thermoplastic film 93 are engaged in lower floor's thermoplastic film 94.
At first, as shown in Figure 12 C, by with upper thermoplastic film 93 the two being connected by the heat-sealing check valve film 90 of the position shown in the thick line.By this step, the remover 87 that is coated in advance on the check valve film 90 is attached to upper thermoplastic film 93 to form air lead part 88 along knit line 79a and 79b.Secondly, air flow maze part 86 is by formation such as knit line 86a-86c.Open the end of air flow maze part 86, to form air discharge port 84.
Subsequently, shown in Figure 12 D, by check valve film 90 and upper thermoplastic film 93 are connected with lower floor thermoplastic film 94.By this step, owing to potted line (boundary line) 82 closures are passed through on the border between two air chambers, each air chamber 83 is separated mutually.Yet because remover 87 has stoped the sealing between film, the scope that potted line 82 contains remover 87 is not closed.Therefore, air lead part 88 is formed, and it allows that air is mobile according to mode as shown in Figure 12B.
Figure 13 is a partial cross sectional front view, and it shows an example of the inner structure of check valve 85a of the present invention, and wherein, check valve is made of single thin film and is formed on the thermoplastic film of air-packing device.As previously mentioned, shared air lead part 88 and air flow maze part 86 are formed at check valve film 90 and the upper and lower thermoplastic film 93 and 94 between one of them.In this example, the mode of describing according to 12C in conjunction with the accompanying drawings seals and makes check valve film 90 be connected in upper thermoplastic film 93.
Air flow maze part 86 comprises for example labyrinth arrangement of zigzag air by-pass passage, so that the air-flow that for example refluxes is formed resistance.This zigzag air by-pass passage forms by engaging (heat-sealing) line 86a-86c.Be different from straight air by-pass passage forward, for utilizing pressurized air to the air-packing device inflation, labyrinth part 86 has realized easy operation.Can use the various methods that are used to produce air-flow resistance, the structure of the labyrinth part 86 shown in Figure 12 A-12D and 13 only is an example.Usually, labyrinth arrangement is complicated more, for the area of the required labyrinth part 86 of the resistance that produce to stop air-flow fully just more little.
Figure 14 is a viewgraph of cross-section, and it shows another example of the inner structure of the check valve 85b among the present invention, and wherein, check valve is made of bilayer film and is formed on wherein a slice thermoplastic film of air-packing device.In this example, between upper thermoplastic film 93 and check valve film 90, be provided with additional film 95.Additional film 95 has constituted check valve 85b with check valve film 90.Additional film 95 is connected in upper thermoplastic film 93, so that air is not carried in the space between upper thermoplastic film 93 and lower floor's thermoplastic film 94.
The usefulness of this structure has been to improve the reliability that stops air circulation.That is to say in the check valve of Figure 13, when filling with air, to have upper thermoplastic film 93 bendings of the air chamber of check valve 85 to air chamber 83.And then when being loaded into product in the air-packing device, the surperficial protrusion of product may touch the outside face of the air chamber that wherein has check valve and make it distortion.Because the bending of air chamber, the sealing effectiveness that is produced by check valve may weaken.Additional film 95 among Figure 14 because it is independent of upper thermoplastic film 93, has relaxed this problem.
Figure 15 A and 15B are viewgraph of cross-section, and it shows the inside of the air chamber with check valve 85.In the situation shown in Figure 15 A, pressurized air is introduced in the air-packing device through check valve 85.In the situation shown in Figure 15 B, air-packing device is inflated by appropriateness, so that check valve 85 is operated, thus effectively closed by the in-to-in air pressure.Dotted arrow 89 shows the air-flow among Figure 15 A and the 15B.
As shown in Figure 15 A, from admission port 81 (Figure 12 A-12B) when pumping into, air will flow to each air chamber at air.When portion of air flowed to next exhaust chamber, remaining air then entered current air chamber with to this air chamber is expanded.Because air source (for example air compressor) institute applied pressure, air will flow in the air chamber.Air is discharged by air flow maze part 86 and from the outlet 84 that is positioned at labyrinth part 86 ends.All air chambers finally all are full of pressurized air.
Shown in Figure 15 B, when the air chamber with check valve 85 is expanded to a certain degree, the internal pressure of air will upwards promote check valve film 90, so that it touches upper thermoplastic film 93.Figure 15 B mainly shows the air flow maze part 86 of check valve 85, to show the action situation of check valve 85.When internal pressure arrives enough grades, check valve film 90 and upper thermoplastic film 93 airtight contacts, that is, and check valve 85 closures, thereby the backflow of prevention air.
As mentioned above, according to the present invention, when product dropped or collide, air-packing device can be reduced to impact or vibration to product minimum.The flaky texture of air-packing device folded and impose post heat-seal treatment to it, thus form product to be protected exclusive structure.Air-packing device is made of enclosure portion and pocket portion substantially.Enclosure portion comprises many emptyings air-capacitor device.Pocket portion is formed at the substantial middle place of enclosure portion.Therefore, even big impact or vibration put on air-packing device, pocket portion will not contact with ground.And then because pocket portion can move flexibly, when impact was applied in, it can suppress the impact to wherein product effectively.Check valve in the air-packing device has the unique texture that is used to stop air circulation.Air-packing device of the present invention has the failure-free check valve, and structure is simple relatively, thereby the present invention can provide cheapness and the failure-free air-packing device.
