Description
Technical field
The present invention relates to the gas injection valve (charging air inlet) of the stacked flat dual tubular that forms of thin polymer film.This gas injection valve is installed in as air cushion, various balloon (バ Le one Application) and on the airtight bag that uses, to prevent material and to use as buffer body, cargo movement when the article of packing, transportation destructible, damage.
Background technique
Be installed in as air cushion as described above, various balloon and the air injection valve of the flat dual tubular on the airtight bag that uses, be required by being suppressed between cylindrical wall (thin polymer film) gap that produces improving tightness, backward stop (check), and make the discharging operation of the air in the airtight bag become easy.
As such air injection valve 12, known to Fig. 5 and shown in Figure 6, make the hot amalgamation polymer thin diaphragm of 1 group of the softness that constitutes its cylindrical wall 14,14 ' organize hot amalgamation polymer thin diaphragm 15,15 ' relative coincidence with another, its side edge part 20,20 ' heating are merged and the formation one, integral body is constituted the injection valve (for example, with reference to patent documentation 1) that the flat dual tubular of multi-ply construction forms.
Such air injection valve 12, the mode that outside, the other end that is positioned at airtight bag 1 with an end is positioned at the inside of airtight bag 1 is installed on the airtight bag 1, thereby make the inflow of air, discharge become easy, and has backward stop, therefore, as airtight bag air injection valve, current padded coaming, the cargo movement that is widely used in bale packing, when packing prevents in material or the various balloon.
Patent documentation 1: real public clear 53-44579 communique (the 2nd page, and the 2nd figure, the 4th figure).
Summary of the invention
The air injection valve 12 of this flat dual tubular in order to guarantee backward stop and tightness reliably, must make the width and the satisfied restriction relation to a certain degree of length of air injection valve 12.That is to say, to the width of valve widen, the shorten length of valve all is conditional.On the other hand, in order to enlarge the usability of this air injection valve, be hopeful to be made into the amplitude than broad, the relatively shorter such requirement of length again.
At first, as air injection valve as described above, when the injection of air, expand by the air pressure cylindrical wall, therefore resistance is less, the injection of air can unhinderedly be carried out, but when the injection of air finishes, then require to utilize the interior interior pressure of restorative and airtight bag of cylindrical wall (thin polymer film) to make the air injection valve return to the original shape of flat dual tubular, suppress the adverse current of inner air etc.
Though have the such function of adverse current of a large amount of inner air of instant termination, but be formed on the tube chamber that is positioned between the inboard polymer thin diaphragm 15,15 ', though between two cylindrical wall only a little but be formed with the gap, even it is a small amount of but so long as cause the outflow of air along this gap, will cause the tightness defective.
The cylindrical wall of air injection valve is because be to constitute by having flexible thin polymer film, so, form in the tube chamber of flat dual tubular fluid-tight engagement part and gap portion is discontinuous, irregularly spread all over distribution universally usually.Therefore, making the continuous formation of the distribution obstruction gap portion of fluid-tight engagement part is the bubble-tight important document that improves the air injection valve.
Satisfy the condition of this important document, because of rigidity, flexibility and the width of the cylindrical wall of the air injection valve that constitutes flat dual tubular, length etc. different.But as long as make the length lengthening of air injection valve itself, the probability that satisfies above-mentioned condition will improve.Therefore, in the past generally by making injection valve lengthening itself on probability, to reach satisfied.That is to say, make injection valve lengthening itself, so long as not extreme exception, when injecting, do not have king-sized obstacle, but in the exhaust apparatus with tubulose or flat (ヘ ラ) shape inserts the tube chamber of this injection valve, forcibly the tube chamber is opened under the situation with the operation of discharging inner air, then require the length of valve itself is shortened as much as possible.
The object of the present invention is to provide a kind of to making valve length lengthening for tightness is improved, improving and the opposite like this important document of valve shorten length is adjusted for the efficient of discharging operation, (particularly at front end) forms the fluid-tight engagement part effectively in the tube chamber, makes the in stable condition lasting airtight bag gas injection valve of its fluid-tight engagement in addition.
Airtight bag among the present invention gas injection valve, has flexibility by making, 4 layers rectangular shape thin polymer film 4,4 ', 5,5 ' vertical both side edges portion 10,10 ' heat fuses closes and constitutes flat dual tubular, and be positioned at the outside of airtight bag 1 with an end, the mode that the other end is positioned at the inside of airtight bag 1 is installed in airtight bag on the airtight bag 1 with gas injection valve 2, it is characterized in that, by making above-mentioned 4 layers thin polymer film 4,4 ', 5, be positioned at 2 layers the thin polymer film 4 in the outside among 5 ', 4 ' than being positioned at 2 layers inboard thin polymer film 5,5 ' is short, thereby form 4 layers thin polymer film 4 continuously, 4 ', 5, the thin polymer film 5 of the 5 ' S1 of multilayer portion that is laminated and 2 layers, 5 ' the S2 of individual layer portion that is laminated, and be positioned at the mode of airtight bag 1 with the above-mentioned individual layer S2 of portion, part at the S1 of multilayer portion is installed on the airtight bag 1.At this, so-called " gas " except air, also comprises other gas such as inert gas.
If like this, at first, the S2 of individual layer portion because with the S1 of the multilayer portion soft and low property of specific rigidity height mutually, press and promptly form the fluid-tight engagement part so can respond to adverse current.Meanwhile, the distribution of fluid-tight engagement part becomes the effective and stable status than the S1 of multilayer portion.
Secondly, at multilayer portion S1 place, compare with the S2 of individual layer portion because and equally in the past have higher rigidity, so can carry out the formation of the flat cylindrical of gas injection valve 2 reliably, the thin polymer film 5,5 ' mistake that suppresses the S2 of individual layer portion indirectly from or twist.
Because rich flexible, so the internal layer of relative cylindrical wall (being positioned at inboard thin polymer film 5,5 ') each other might with mistake from or the state fluid-tight engagement of distortion, along the continuous gap of vertical generation of valve.For this reason, according to second scheme of the present invention, preferably at above-mentioned individual layer portion S2 place, at the middle body of front end 8, the thin polymer film 5, the 5 ' heat that only are formed with near the end partly 2 layers fuse the small joining portion 9 of closing.
If like this, by middle body small joining portion 9 is set at the front end 8 of the S2 of individual layer portion, thin polymer film 5, the 5 ' mistake each other that can directly suppress to constitute internal layer helps the formation of fluid-tight engagement part from, distortion, and the in stable condition of fluid-tight engagement continued.
Though the front end 8 part underground heat of the S2 of individual layer portion (internal layer) are fused close, can make the reduced cross-sectional area of the front opening part of the S2 of individual layer portion, because be front end 8, so its influence is less towards the inside of airtight bag 1 so that small joining portion 9 to be set.In addition because the tube that when exhaust, is inserted into injection valve in the chamber 11 tubulose or the exhaust apparatus of flat also there is no need to pass this front end 8, so almost there is not the harmful effect on the function.
When forming stable fluid-tight engagement part like this on the front end 8 of the inside of airtight bag 1, the interior pressure in the airtight bag 1 can be oppressed cylindrical wall, and the distribution of fluid-tight engagement part is further expanded, and tightness, backward stop personality are improved outward.
According to the 3rd scheme of the present invention, above-mentioned 4 layers thin polymer film 4,4 ', 5,5 ', be preferably and bend, form 4 layers respectively by thin polymer film 3,3 ' and constitute, and be set as the structure that its kink 3a, 3a ' are positioned at the outside of airtight bag 12 rectangular shapes.
If like this, make because can be bent to form 4 layers, so make simple by thin polymer film 3,3 ' with 2 rectangular shapes.
As mentioned above, because the present invention makes 2 layers of ratio that are positioned at the outside among 4 layers the thin polymer film of rectangular shape be positioned at 2 layers of inboard weak point, so can regulate and make valve length lengthening for tightness is risen, rise and make the opposite like this important document of valve shorten length for the efficient of bleeding, (especially in the front end) forms the fluid-tight engagement part in the tube chamber effectively, makes its fluid-tight engagement in stable condition and lasting in addition.
Thus, compare with gas injection valve in the past, even if make the width of valve increase, make the shorten length of valve, also can be rapidly and make the cylindrical wall fluid-tight engagement all sidedly to improve tightness, backward stop, make its state continuance, can more easily carry out the discharging operation of the gas in the airtight bag simultaneously.

Embodiment
Below, with reference to the accompanying drawings example of the present invention is described.
Fig. 1 is the amplification view of the airtight bag of an example of the present invention with the installing part of air injection valve, Fig. 2 is the sectional drawing of the A-A line of Fig. 1, Fig. 3 is the sectional drawing of the B-B line of Fig. 1, and Fig. 4 is the planimetric map that is equiped with the airtight bag of air injection valve of the present invention.
As Fig. 1～shown in Figure 3, be installed in the air injection valve 2 on the airtight bag 1, be to install (heat fuses and closes) on airtight bag 1 in mode that outside, the other end that an end is positioned at airtight bag 1 are positioned at the inside of airtight bag 1.In addition, this airtight bag 1 for example is constituted as the double layer construction that the interior pack by ox-hide outer pack made of paper and nylon polyethylene film system constitutes, and air injection valve 2 is fused by heat and is combined in this in pack.
By making 2 layers the thin polymer film 4,4 ' that is positioned at the outside among 4 layers the thin polymer film 4,4 ', 5,5 ', 2 layers inboard thin polymer film 5,5 ' is short than being positioned at, thereby forms the S2 of individual layer portion that the S1 of multilayer portion that 4 layers thin polymer film 4,4 ', 5,5 ' is laminated into and coupled continuous 2 layers thin polymer film 5,5 ' are laminated into continuously.Be positioned at the mode of airtight bag 1 with the S2 of individual layer portion, fuse by heat to close in the part of the S1 of multilayer portion and be installed on the airtight bag 1.In addition, be positioned between 2 layers the thin polymer film 4,4 ' in the outside, be positioned at length between the 2 layers inboard thin polymer film 5,5 ', width is identical.Be by with 2 elongated rectangular shape polymer thin diaphragms 3,3 ' bending, and form 2 layers the thin polymer film 4 that is positioned at the outside, 4 ' and be positioned at 2 layers inboard thin polymer film 5,5 '.Their kink 3a, 3a ' is positioned at the outside of airtight bag 1.That is to say, be set as continuous structure in the outside of airtight bag 1.
That is to say, 2 layers the thin polymer film 4 in the outside, 4 ' and the S1 of multilayer portion that coincides of inboard 2 layers thin polymer film 5,5 ', mutually continuous with the S2 of individual layer portion of 2 layers the thin polymer film 5 that 2 layers thin polymer film 4 than the outside, the 4 ' inboard of further extending are only arranged, 5 ' part, constitute stepped.Therefore, the part of the air injection valve 2 of airtight bag 1, foreign side's side is made of the S1 of multilayer portion, and interior side's side is made of the S2 of individual layer portion.
In addition, the middle body of the front end 8 of the S2 of individual layer portion (open sides end), as shown in Fig. 3 amplifies like that, make the thin polymer film 5,5 ' of opposed inside, small joining portion 9 by the short-term shape only near the end part underground heat fuse and close, promptly form tight contact segment to be easy to responding to countercurrent pressure.
Such air injection valve 2 for example as shown in Figure 4, is installed in the front and sees on the bight of airtight bag 1 of rectangular shaped as the air injection valve with flexible flat dual tubular, be used for injecting, exhausting air.
According to constitute as mentioned above like that, the S2 of individual layer portion is flexible higher than the S1 of multilayer portion, can respond to adverse current and press formation fluid-tight engagement portion rapidly.The distribution of this fluid-tight engagement portion can become the effective and stable status than the S1 of multilayer portion.
Thus, by to air injection valve 2, use the air gun (エ ア ガ Application) (for example エ グ ザ イ ヤ one rifle and the pipe (for example diameter is 25mm) of Co., Ltd.'s Block ロ one バ Star Network (exabyte) system) that is used for filling air to inflate by pipe (チ ュ one Block), can expand by chien shih airtight bag 1 when short, when airtight bag 1 reaches certain when big or small, press in the airtight bag 1 to reach certain pressure.
But, because thin polymer film 5,5 ' is rich flexible, the thin polymer film 5,5 ' that therefore will make opposed inside each other with mistake from or the state fluid-tight engagement of distortion, its result just might produce continuous gap on the cylinder axis direction of air injection valve 2.
For this reason, in this example, by front end 8 places small joining portion 9 is set at the S2 of individual layer portion, can produce direct suppress between the inboard thin polymer film 5,5 ' mistake from, twist, help the formation of fluid-tight engagement part, make the in stable condition lasting effect of fluid-tight engagement in addition.In addition, though make between inboard thin polymer film 5,5 ' the front end small joint so that small joining portion to be set, the front end opening of the S2 of the individual layer portion sectional area between dividing is diminished, but because be front end towards the inside of airtight bag 1, so its influence is less, in addition, because the exhaust apparatus that is inserted into tubulose in the chamber 11 or flat during exhaust also needn't its front end 8 of break-through, so almost there is not the influence on the performance.
Secondly, at multilayer portion S1 place, compare with the S2 of individual layer portion because have higher rigidity samely, so can carry out the formation of the flat cylindrical of air injection valve 2 reliably, the thin polymer film 5,5 ' mistake that suppresses the S2 of individual layer portion of adjacency indirectly is from, distortion.
By forming stable fluid-tight engagement part at front end 8 places like this towards the air injection valve 2 of the inside of airtight bag 1, thereby the interior pressure in the airtight bag 1 can be oppressed the thin polymer film 5,5 ' of the inboard that constitutes the individual layer S2 of portion, the distribution of fluid-tight engagement part is further enlarged, thereby can realize making extraordinarily tightness, backward stop raising etc.
In above-mentioned example, make the thin polymer film 4 in the outside and inboard thin polymer film 5 and the thin polymer film 4 ' in the outside and the thin polymer film 5 ' of inboard, constitute by bending a slice thin polymer film 3,3 ' sheet respectively, but also can make its by separately from each other thin polymer film, be that 4 different thin polymer films of length (thin polymer films of the thin polymer film of 2 rectangular shapes that length is short, 2 rectangular shapes that length is long) constitute.
Above-mentioned small joining portion 9 is to form in the mode of extending to the end of opposition side from the ora terminalis of front end 8, but and nonessential such formation, also can be to form from the mode of extending to the end of opposition side from the position that the ora terminalis of front end 8 departs from a little.In addition, small joining portion 9 is the short-term shape, but is not limited to this, for example also can be point-like.That is to say, so long as the mistake that can directly suppress to constitute between the thin polymer film 5,5 ' of internal layer gets final product from the shape of, distortion.
