Fig. 6-15 illustrates an example of the boiler check valve that is used for inflating type cushioning package body of the present invention.
Fig. 6 illustrate constitute boiler check valve want portion by the soft passage body of making to be opened/closed.This passage body 101 forms by bonding 2 soft, but channel part 102 openings become tubular.In addition, be sandwiched in the anti-inclined to one side sheet 103 that keeps passage body 101 between following supporting mass and the elastic body in the formation of the both sides of channel part 102.Symbol 104 is the guide part from the passage body 101 of the position protrusion of anti-inclined to one side sheet 103.
As above-mentioned passage body 101, preferably select employed soft from sheet rubber, plastic sheet, wet-strong paper, waterproof sheet, aluminium foil or its composite sheet.
In Fig. 6, the state of the occasion that the channel part 102 of passage body 101 closes (a) and (b) is shown, (c) and the state that channel part 102 is opened, gas passes through of passage body 101 (d) is shown.
Thereby Fig. 7 illustrates the occasion of the channel part 102 of bonding 2 soft heat welded passage body 101.The channel part 102 of the taper that shrinks towards the opposition side of guide part 104 (a) is shown in the figure.(b) illustrate and shrink then towards the opposition side of guide part 104 that its front end becomes barrel-contoured channel part 102.(c) channel part 102 that illustrates has the part of Rack towards the opposition side of guide part 104, shrinks then, and afterwards, its front end becomes tubular.(d) the barrel-contoured channel part 102 that forms with guide part 104 same diameter is shown.
The width of the channel part 102 of above-mentioned passage body 101 be preferably gas can be smoothly by and also all not excessive degree of boiler check valve 3.Certainly, when carrying out packing job, be preferably and the corresponding size of diameter of the rhabodoid that inserts by rhabodoids such as straws.
Means as form channel part 102 at above-mentioned passage body 101 are preferably bonding 2 soft means in anti-inclined to one side sheet 103 part heat welded, but also can be other formation means certainly.When the anti-inclined to one side sheet 103 of welding, as long as the border of welding and channel part 102 only.
Fig. 8 (a)-(b) illustrates and is used to clamp above-mentioned passage body 101 and opens and closes the particularly supporting mass and the elastomeric example of automatic airtight.Supporting mass 105 forms respectively with elastic body 106 (not shown)s.End at supporting mass 105 is formed extended at both sides lid 108 to left and right direction by plastic hinge 107.This supporting mass 105, plastic hinge 107, and lid 108 preferably will be configured as the regulation shape by the plastic material that polyethylene, polypropylene, polyester, polycarbonate etc. constitute by injection moulding.Certainly, the method for shaping is not limited to this injection moulding.
In Fig. 8 (a), be convexly equipped with maintenance guide part 109 respectively in the both sides, top and the both sides, bottom of supporting mass 105.In addition, will insert guide part 110 in the upper end of above-mentioned supporting mass 105 central authorities and be set to the position of inserting rhabodoid.
In the example of Fig. 8 (a), above-mentioned lid 108 forms the guide groove 112 of the circular-arc section of accommodating the passage body 101 by rhabodoid in the cardinal principle of flat board central authorities, forms a pair of rib 113 that is used to push the elastic body 106 of sheet in its both sides along the length direction of passage body 101.The length of this rib 113 and shape, position and quantity can be corresponding to suitably decisions such as the thickness of above-mentioned elastic body 106 and size.But, preferably have sufficient length and shape, position and the quantity of the switching that does not damage elastic body 106.
In addition, the hook of symbol 114 for engaging with the overhang bracket body 105 of being located at lid 108.This hook 114 is embedded into the support cut 115 that penetrates into ground, the end setting of supporting mass 105 along thickness direction, is used for anticreep.With lid 108 fixed bearing body 105 and elastic body 106 under the state of as prescribed curvature bending, can obtain the very good boiler check valve of durability 3 by like this.
In the example of Fig. 8 (b), this lid 108 is along being formed for elastic body 106 is pressed to the rib 113 of the both sides of guide groove 112 with the rectangular direction of the length direction of passage body 101.
In the example of Fig. 8 (c), this lid 108 is linked the guide groove 112 of the circular section of central authorities from two ends along supporting mass 105 with bevelled state inwardly, is not formed for pushing the rib 113 of above-mentioned elastic body 106.
In the above description illustration the coupling device that constitutes by hook 114 and support cut 115, but not only be such engagement means, also boiler check valve 3 can be sealing into the tubular sheet, or use means or other shape and structure such as thermal welding.
Above-mentioned supporting mass 105 and lid 108 can be same thickness, also can make the wall thickness difference.With regard to regard to the relation of passage body 101, supporting mass 105 and lid 108 need the thickness of indeformable degree, and in addition, passage body 101 is owing to need the flexible thickness that approaches that adopt, and in addition, elastic body 106 need be specific thickness from its function consideration.Certainly, elastic body 106 is the thickest like passage body 101.
As the material of above-mentioned passage body 101 and elastic body 106, can be from plastic sheet, sheetmetal or to select its composite sheet as constituent material.As the example of plastic sheet, can list polyethylene, polypropylene, polyester, polycarbonate etc.In this occasion, preferably make passage body 101 be identical material.
As the thickness of above-mentioned elastic body 106, state the occasion of plastic sheets such as polyethylene in the use, preferably use about 0.1-0.5mm thickness.In addition, for the size of supporting mass and elastic body 105,106, be example with the occasion of rectangle, best transverse axis: longitudinal axis ratio is about 2-1.5: 1.For example, press transverse axis: the actual size of the longitudinal axis can be 40mm: 25mm, 35mm: 20mm, 30mm: the 11mm equidimension.
Make the radius of curvature of the occasion of above-mentioned supporting mass 105 and elastic body 106 bendings be preferably 11mm-40mm.Under small curve, the power of supporting mass 105 and elastic body 106 clamping passage bodies 101 is stronger, and the reaction of the plug of relative tubular body 131 is better.On the contrary, when radius of curvature is increased, can adjust supporting mass 105 and elastic body 106 and clamp the power of passage body 101 and pressurization when transferring or the increase and decrease of the power during the plug rhabodoid.
As material, preferably constitute bag, formation passage body 101, supporting mass 105, elastic body 106, the plastic material of lid 108 and all uses homogenous material of sheet class of packaging body 1.For example can confirm that the material of the composite sheet formation of plastics systems or itself and aluminium foil etc. is very suitable to the problems referred to above that solve this invention as the aspects such as processing after the commonality of material, processability, the rubbishization.
Fig. 9-Figure 12 illustrates by supporting mass 105 and elastic body 106 and sandwiches the state that passage body 101 constitutes this boiler check valve 3.Promptly, Fig. 9 illustrates the state of opening supporting mass 105 and lid 108, Figure 10 illustrates along keeping guide part 109 to accommodate the microscler state that constitutes passage body 101 and elastic body 106, and Figure 11 illustrates the support cut 115 central firmly states of passage body 101 both sides that the hook 114 of lid 108 are embedded into supporting mass 105.In Figure 11 of this completion status was shown, passage body 101 was pressed to supporting mass 105 with elastic body 106 by the rib 113 of lid 108.
The boiler check valve 3 of An Zhuaning is as Figure 12 with passage body 101 is held in circular-arc to carry out crooked state along with the bending of supporting mass 105 and elastic body 106 as shown in Figure 13 like this, and this lid 108 is positioned at the position of its string.Like this, can keep the shape of elastic bodys 106 along supporting mass 105 by lid 108, and, can positively keep its bending by above-mentioned rib 113, securely crimping passage body 101.
Below, the effect of this boiler check valve 3 that constitutes like this is described.
Figure 14 is illustrated in the state that inserts straw and other tubular body 131 in the passage body 101.This boiler check valve 3 is by being inserted into tubular body 131 inside of the channel part 102 of passage body 101, thereby removes the closed contact by the channel part 102 of supporting mass 105 and elastic body 106 crimping, guarantees passage.In this figure, use straw etc. are guaranteed more certain passage as such tubular body 131.
In Figure 15 that above-mentioned effect is described in more detail, insert the front end of the tubular body 131 that constitutes by straw etc. from the upper end of the guide part 104 of passage body 101.In fact, be set to this part, can form the shape that is easy to insert tubular body 131 by inserting guide part.When depressing tubular body 131 at leisure as figure (a)-(d), the channel part 102 of passage body 101 is open with each elastic body 106.
When further depressing tubular body 131, the elastic body 106 that is pressed to supporting mass 105 by lid 108 is open in total length along tubular body 131, can make the gas free flow as figure (d).Therefore, can use the tubular body 131 that constitutes by straw etc. to carry out packing job simply.
On the contrary, in the occasion of the channel part 102 of wanting closing passage body 101, pull out tubular body 131 and get final product.That is, elastic body 106 returns to original position at leisure, and closed contact is to supporting mass 105, and the channel part 102 of passage body 101 along the order of figure (d)-(a), makes total length closed contact automatically on the contrary once more.At this moment, as applying the pressure that the other way around object is pushed back at boiler check valve 3, then transfer the pressure to passage body 101 by supporting mass 105 and elastic body 106, the channel part 102 of passage body 101 closes.
Show the occasion of switching of carrying out the channel part 102 of passage body 101 by the tubular body 131 that constitutes by straw etc. in the above description, but an end of passage body 101 is opened, revolting the elastic force pressurization of elastic body 106, simultaneously make object pass through channel part 102 forcibly, thereby be pressed into.
Prevent that by boiler check valve 3 adverse current of the air in the energy chamber from spilling like this, so, can keep swelling state for a long time.
As above-mentioned elastic body 106, can use rubber-like rhabodoid and spring tube to replace the sheet class, particularly can use silicone tube preferably as spring tube.
When using the inflating type cushioning package body of the present invention that constitutes like this, as shown in Figure 16, at first do not enter under the normality of energy chamber at air, the peristome 13 expansion formation tubulars with packaging body 1 are inserted into this place with object 2.After making object 2 be positioned at the centre substantially,, energy chamber is expanded from boiler check valve 3 filling air.
On the contrary, the occasion taking out object 2 can make the energy chamber atrophy by above-mentioned gimmick from boiler check valve 3 air-outs, takes out object 2.
As described above, inflating type cushioning package body of the present invention can be by the turnover of air repeated use repeatedly.
In addition, as more specifically utilizing method, as shown in Figure 17, mounting knob 14, form bottle handbag (1), in addition, basically be not subjected to the restriction of size, so, the conveying (b) of the article of long size also can be applicable to the size of the object that should keep accordingly.In the occasion of (a), consider the situation that makes escape of air just in case energy chamber sustains damage, take the measure that prevents that object from falling bottom being preferably in.
In the different occasion of sheet that as the configuration example 2 of the configuration example 1 of above-mentioned Fig. 2 and Fig. 3, constitutes inside and outside wall, by increasing the thickness of the sheet that constitutes outer wall, or have flexible and tough by use to be the high material of mechanical strength, can to prevent to damage the leakage of air that causes.Here, said mechanical strength refers to stretch, elasticity, shock-resistant, fracture etc. are used to estimate flexible sheets and are difficult for because of needed all means of the injured degree of external cause.
Figure 18-Figure 26 illustrates the 2nd form of implementation of inflating type cushioning package body of the present invention.In above-mentioned the 1st form of implementation, the type that a pair of energy chamber directly links to each other is shown, but in this example, the type that links to each other indirectly is shown.
That is, in precedent, as shown in Figure 1,2 energy chamber at both ends direct connections, therefore, in the occasion that air is filled to energy chamber, no matter whether the cardinal principle central portion section of packaging body is expanded to circle substantially, the end weld portion all produces the warpage part in order to keep linearity.About the shape of the object that warpage is also accommodated, its position and number of times are various, and the shape of the end when accommodating object is not attractive in appearance.
Therefore, the applicant investigates the back and finds, isolates at certain intervals by making 2 energy chambers, can address this problem.
That is, like that, isolate the engagement end portion 15 of 2 energy chambers by connecting portion 16 as Figure 18 (b) and (c), weld portion is oblong attractive in appearance substantially, the size of the object that this is not accommodated and the influence of size.
Like this, side not only, and shown in this figure (a) like that, positive shape is also very attractive in appearance, displaying the best of commodity etc.In addition, as mounting knob 14, then can form the high commodity packaging of displaying property.
Figure 19-Figure 26 illustrates this configuration example.
Figure 19 is illustrated in the occasion that the 1st configuration example is used 3 flexible sheets.
At first, prepare the sheet 7 of formation inwall of 1 doubling and 2 tabular sheet 8A, 8B that constitute outer walls totally 3 flexible sheets.(a)
In the size of sheet, the width A of the sheet 7 of doubling is littler than the width A of other sheet 8A, 8B.This be because, when overlap 3 to around when carrying out welding, joggling part 9 ground of not welding sheet 7 form this part the interconnecting part of energy chamber.
3 sheets adjusting to such size are overlapped shown in this figure (b) like that, along the welding (arrow portion) on every side of sheet 8.At this moment, boiler check valve 3 is arranged between sheet 7 and 8.When welding, more specifically say the removing of sheet 7 to all ends and sheet 8 weldings beyond the folding part 9.In desired position up and down weld bond 17A and 17B are set.Weld bond 17A is along the overall with setting, and 17B stays the interconnecting part 18 that connects 2 energy chambers.In this occasion, such shown in this figure (c), when weld portion is formed the L font, only form interconnecting part 18, during the filling air, such shown in Figure 18 (b), the connecting portion 16 of bottom still is the plane, when shown in Figure 19 (d), during like that with the open state welding, shown in Figure 18 (c), like that, another energy chamber being set again in the bottom.
(e) be skiagraph.Become the such state of cylindrical body of flattening.
As the material of flexibility sheet, can be from plastic sheet, sheetmetal or to select its composite sheet as constituent material.As the example of plastic sheet, can list polyethylene, polypropylene, polyester, polycarbonate, nylon resin etc.By with these soft or composite sheet as material, 2 sheet material tablets are bonding, with Rack to sealing around it, thereby heat welded and forming, perhaps, also can be outside layer for example uses polyethylene or polypropylene, la m to use such material of nylon resin or polyester.
Figure 21 is illustrated in the 2nd configuration example the occasion of using after 2 mutual doublings of flexible sheets.
At first, the sheet 8 (a) of preparing to constitute the sheet 7 of inwall and constituting outer wall.For its width dimensions (A), (B), sheet 8 one sides' width is bigger than sheet 7.This be for the identical reason of configuration example shown in the preceding figure.
Respectively after the doubling, make it respectively towards equidirectional, sheet 7 is inserted between the sheet 8 of doubling (b), in addition, boiler check valve 3 is inserted, welding around the sheet 8 simultaneously, is provided with weld bond (c) from upper and lower side in desired position.In this occasion, weld bond 17A is along the overall with setting, and 17B stays the interconnecting part 18 that is communicated with 2 energy chambers.In this occasion, such shown in this figure (4), when weld portion is formed the L font, only form interconnecting part 18, during the filling air, such shown in Figure 18 (b), the connecting portion 16 of bottom still is the plane, when shown in Figure 21 (5), during like that with the open state welding, shown in Figure 18 (3), like that, another energy chamber being set again in the bottom.
(f) be skiagraph.Become the such state of cylindrical body of flattening.
Figure 22 is illustrated in the occasion that the 3rd configuration example is used the tubular sheet.
At first, prepare (a) such tubular flexible sheets, 4 weld bonds are set in desired position.In addition, insert boiler check valve 3,2 ends 10 of welding 1 end.
In this occasion, the interconnecting part 18 that weld bond 17 all will be communicated with energy chamber forms with staying.But, for 17B, shown in this figure (d), like that, when weld portion is formed the L font, only form interconnecting part 18, during the filling air, like that, the connecting portion 16 of bottom remains plane shown in Figure 18 (b), but when shown in Figure 21 (e) during like that with the open state welding, shown in Figure 18 (c), like that, another energy chamber can be set again in the bottom.
In this routine occasion, 17A also is provided with interconnecting part, so in Figure 18 (c), the connecting portion 16 on top also produces minor air cell.
(f) be skiagraph.Become such state that cylindrical body is flattened.
Though be the easiest formation, make the inside piece closed contact in lateral film at joggling part, so the connection of the air of energy chamber is insufficient, even the filling air only is that to have the tendency that the energy chamber of boiler check valve 3 expands also stronger.
Figure 23 is illustrated in the occasion that only is made of 1 sheet in the 4th configuration example.
Prepare 1 flexible sheets, this flexible sheets is connected with the part 7 of formation inwall such shown in this figure (a) and constitutes the part 8 of outer wall.The width of 2 parts is not both in the occasion of using the laminated material of polyethylene resin (PE) and nylon resin (NY) as the flexible sheets of material, with the mutual welding of polyethylene.That is, in the drawings, make the outside become nylon resin, the inboard folds with becoming poly-vinyl resin.In the occasion of the such composite material of the homogenous material sheet, the PE-NY-PE that only are poly-vinyl resin, because nylon resin that can not welding do not join, so, also can be same widths.This point all is identical to all embodiment of the present invention.
Then, shown in (b), clamp boiler check valve 3 doublings like that,, form weld bond 17B simultaneously along the end welding.In addition, as with its as (c) and (d) like that, welding end 12 after the doubling.
This figure (d) is the front elevation of normality, becomes the such state of cylindrical body that flattens.
Figure 24 prevents member for the warpage of energy chamber interconnecting part 18.
Fig. 4, Fig. 5, Figure 22, and as shown in Figure 23 method in, such shown in Figure 24 (d), the sheet 8 of the sheet 7 of formation inwall and formation outer wall is at the joggling part closed contact, can not guarantee the connection of energy chamber 4,5, not by interconnecting part 18, the energy chamber 4 that only has a side of boiler check valve 3 expands from boiler check valve 3 leaked-in airs, can not 2 energy chambers be expanded balance, so problem such as be can not determine in the position that produces the object accommodate.
Therefore, prevent member 19, shown in Figure 24 (e), guarantee interconnecting part 18 like that, so energy chamber can expand substantially equably by in interconnecting part 18, inserting the closed contact that forms by elastic body.
This closed contact prevents that member from becoming the such shape that vertical rib is formed at plane member in the drawings, but as being the shape that has the appropriateness flexibility and flexibly guarantee passage, can not be graphic shape also then, also can be cylindrical body etc.
Figure 25 is the 5th configuration example, is the modified form of above-mentioned energy chamber connection method.
Such as shown in the figure, use 2 different slightly flexible sheets 11 of width or form 2 overlapping bags in different 1 flexible sheets 11 of central width dimensions.The separately use of these material piece determines according to the difference of the sandwich structure of composite sheet.
That is, for example, must make the overlapping opposite to each other and welding of face of PE in the occasion of the lamination sheet that uses PE-NY.At this moment, for the welding at the both ends 22 of carrying out operation (e), the width dimensions of 2 sheets of coincidence is adjusted on the PE face ground that must expose the sheet that is in the below.The occasion of the lamination sheet of PE-NY-PE does not just have this necessity.
At first, 2 flexible sheets 11 are overlapped or, only boiler check valve 3, the boiler check valve installation portion 20 on a limit removed the other places then incessantly around the welding 1 flexible sheets 11 doubling.This moment as shown in the figure, the weld bond 21 of short transverse be in from about end 22 position that enters into the certain size inboard.This is of a size of a half-size scale (d=D/2) at the interval of central disrumpent feelings weld bond 23.Like this, peristome only forms energy chamber at 1 position, so also can prevent to leak.In addition, clamp 2 parallel disrumpent feelings weld bonds 23 of boiler check valve installation portion 20,3 energy chambers (24A, 24B, 24C) are set by setting.This is disrumpent feelings, and weld bond 23 is the dotted line shape, at 3 energy chambers of part connection of not welding.
When the welding that is used to form 3 energy chambers finishes, boiler check valve 3 is inserted into opening 20 weldings of being clamped by disrumpent feelings weld bond 23 fixes.
Then, shown in (d),, hold 22 also weldings about alignment like that with flexible sheets 11 doublings.
As material piece, the occasion of in folding figure, being used behind continuous 1 sheet (roll film etc.) of the broad ways of (b) for example, make the folding position be in the cardinal principle central authorities of the Width (short transverse of (b) among the figure) of sheet substantially, make the width difference of the sheet up and down after folding, and cut off along fold line, in addition, make the center-aligned of two Width, arrive the operation of (c).
When using the inflating type cushioning package body that constitutes like this, shown in Figure 26 (a), inject air from boiler check valve 3 like that, the energy chamber 24B of central authorities at first expands, air is from flowing into energy chamber 24A, the 24C of both sides between the disrumpent feelings weld bond 23 then, so, like that, air flows into two energy chambers equably shown in this figure (b).Therefore, object 2 is easy to accommodate the central portion of this packaging body.
Figure 27 illustrates the 6th configuration example.
In the drawings, prepare 2 tubular flexible sheets, sheet 6 is inserted into coincidence in the sheet 7,2 (totally 4) disrumpent feelings weld bonds 23 that separate desired spaced and parallel are set respectively in position in opposite directions.Here, along circumferentially being divided into 4 parts.Boiler check valve 3 is clamped by interior outer plate 6,7 in end at the crevice of being clamped by disrumpent feelings weld bond 23, the two ends of welding tubular sheet and finishing.
By such formation, such as shown in figure 28, this inflating type cushioning package body is made of the energy chamber of whole connections.
When constituting like that as shown above, not necessarily leave no choice but use and cut into tetragonal and formed barrel-contoured flexible sheets in advance, as use make to go up continuous sheet by the welding of suitably configuration and cut off that operation finally forms and claim in the invention identical construction put down in writing, then gimmick of Xing Chenging and formation are not limited, any technology that replaceable application those skilled in the art can remember.
