Each bag 1 is formed by two water-soluble substrates 2,3, and these two water-soluble substrates 2,3 can be called as base net 2 and upper wire or cover net 3.Any suitable water-soluble substrate can be used.The bag 1 with two compartments 1a, 1b has been shown in Fig. 1, Fig. 3, Fig. 5, Fig. 7, Figure 13, Figure 14.The bag 1 with three compartments 1a, 1b, 1c has been shown in Fig. 2, Fig. 4, Fig. 8, Fig. 9, Figure 10, Figure 11, Figure 12, Figure 15, Figure 17.The bag 1 with four compartments 1a, 1b, 1c, 1d has been shown in Fig. 6, Figure 16.Each bag 1 is symmetrical about the weld bond 4 between base net 2 and top cover net 3.Each compartment 1a, 1b, 1c, 1d are shaping between base net 2 and upper wire or cover net 3.The footprint 5 of bag 1 and the quantity of compartment 1a, 1b, 1c, 1d, shape and layout are only exemplary, and other structure that can adopt it will be apparent to those skilled in the art that.The planar view of bag 1 when term " footprint " is defined as watching above the upper wire or cover net 3 of bag 1.
Water-soluble substrate usually lacks hardness with regard to its material person's character.Therefore, when making water-soluble bag forming with two water-soluble substrates, the bag of acquisition itself will have the tendency lacking hardness or planar strength, and when customer holds, this will not have attractive soft appearance to bag.Claim herein thisly to lack hardness or planar strength is plane deformation.Although substantially can be made up of polyvinyl alcohol resin by the water-soluble substrate of major part of shaping (such as Heat forming or vacuum forming) now, can use other can by shaping water-soluble substrate to implement the present invention.
In the present invention, the plane deformation of multiple compartment pouch can be overcome by one or more following factor or significantly reduce:
The relative position of compartment 1a, 1b, 1c, 1d i) in footprint 5 and/or shape,
Ii) each compartment 1a, 1b, 1c, 1d are filled into the level of at least 80% (preferably at least 90%) of volume available,
Iii) relative thickness of top cover net 3 and base net 2 is selected, so that sealed together and after discharging described bag from forming machine or shaped device, utilize retraction or the contraction of base net 2 at described net.
These features of present discussion and they are on the impact of plane deformation of the bag 1 obtained.It is possible that these features can be used alone, or any two use in combination, or preferably all three use in combination.The present invention extends to the bag 1 of formation like this and comprises the bag 1 formed like this.The aspect of the present invention related to herein can comprise any one in these factors, and we are not intended to the present invention is limited by these aspects specifically mentioned.
the position of compartment and/or shape
Plane deformation can be reduced as in compartment by adopting periphery compartment.Term " periphery " in this context is described in the compartment near the periphery of bag.Periphery compartment can be square or the rectangle at the angle with cavetto in its simplest form, maximally can use the area of footprint, and therefore provides the compartment fill volume of maximum possible.When just seeing on the net from upper cap, this square or rectangular outer perimeter compartment can along the cut edges of bag, its outer boundaries from the cut edge retrude of bag, such as, apart from the cut edge at least 1.5mm of bag.Square or rectangular outer perimeter compartment due to Market Reasons or may like other shape (such as, the pentagon at the triangle with the angle of cavetto or the angle with cavetto is circular or oval, but these shapes are not limited to) other reason and be rejected.It is evident that, be not the combination packing volume that square or rectangular outer perimeter compartment can reduce compartment in bag, and leave the larger flange around periphery or half periphery compartment.
Periphery compartment can be divided into two or more independent compartments, to increase the quantity of compartment in the bag of given footprint.But, by segmentation periphery compartment, may planar stability be lost.The present invention overcomes the loss of this planar stability by compartment design.As an example, if periphery compartment is divided into two and half periphery compartments, stop unless then introduced the project organization corrected, otherwise bag may the jointing line place of sealing area between half periphery compartment bend.Compared with the bag with planar stability, the multiple compartment pouch that can bend has less attractive force to customer.
One or more compartment in multiple compartment pouch can not be filled, so that the plane deformation of extra opposing bag.
compartment fill level
By each compartment of bag being filled at least 80% (preferably at least 90%) of its volume available, plane deformation can be reduced.What have been found that this percentum of the volume available of each compartment is filled with the planar stability helping bag.
net thickness
The thickness of top cover net 3 can be chosen as 30% to 90% of the thickness of base net 2, preferably 50% to 75%.In this way, when sealing bag 1 and after it being discharged from machine, base net 2 is retracted or shunk to reduce the internal volume of each compartment.The pressure produced like this in each compartment in bag 1 can cause thinner top cover net 3 to expand into typically larger than the contraction of base net 2 degree, increases the internal volume of each compartment of bag 1 thus.This can cause being formed substantially about the bag 1 of weld bond 5 symmetry.Figure 18 illustrates this of bag 1 of discharging from the chamber 6 of the rotatable former 7 being configured with periphery to reconfigure.Former 7 can be circular as shown in figure 18, but this is not necessary, also can use other structure of former, such as, be configured with the rotatable former of flat horizontal surface.Shown in WO2011/061628, describe the example of operable cylinder and horizontal form device, reader obtains more details with reference to it.
Although the minimizing of the plane deformation provided by any single factor may be not enough to guarantee the plane hardness of bag, when all three factors in conjunction with time, plane hardness can against expectation increase, this on the contrary give multiple compartment pouch of the present invention the market advantage is provided.
Referring now to Figure 19 and Figure 20, exemplified with the filling example of filling according to multiple compartment pouch 1 of the present invention, but these examples do not limit.By stride across the net of machine by shaping, to be filled and and to be known as by the quantity of the bag 1 sealed be the quantity of track or route.

In accompanying drawing 20, fill the bag 1 with three compartments 1a, 1b, 1c being similar to the bag shown in Figure 15.The rotatable former 7 of bag maker can be constructed to shown in WO2011/061628 and describe there is periphery 7a or alternatively there is flat horizontal surface.Compartment 1a, 1b, 1c can be filled by head 8a, 8b, 8c.Head 8a, 8b, 8c can be tuckers.Head 8a, 8b, 8c can be constructed to add fluid, gel, powder or particle, such as, for the nozzle injector of fluid or gel or the spiral tucker for powder and particle.In this embodiment, head 8a, 8b are constructed to add fluid or gel, and head 8c is constructed to add powder or particle.Head 8a, 8b can be connected to the supply for identical or different fluid or gel.Similar configuration can be provided for each track of net or route that stride across machine.Head in different track or route can be connected to identical or different material supply.It is contemplated that other configuration of head 8a, 8b, 8c of any combination for carrying fluid, gel, powder and particle.The method is equally applicable to the situation that multiple compartment pouch comprises two or more compartments.Usually, a filling head is provided for each compartment.
Referring now to Figure 21, exemplified with the method for arranging head.Head can be arranged in available restricted space the space produced for multiple.In one arrangement, head can tilt toward each other.Such as, for fluid or gel head 8a and can tilt toward each other for the head 8b of powder or particle.In another kind is arranged, the head 8b for powder or particle can be provided with chute 9.Fluid or gel-filled head 8a and chute 9 can tilt toward each other.The chamber 6 that head 8a, 8b can be arranged in along former 7 when it advances has made the usable time of padding increase thus, and the product be filled can more uniformly be stretched along the compartment in base net.
Arrange by using above-mentioned filling and/or pass through the software of the integrated padding of establishment and machine operating speed, the compartment of multiple compartment pouch 1 can be filled during reaching the time gap of 1 second.In this way, described machine can provide the output of per minute about 60 bags for each track of machine or route.When particle or powder solid product, filling device is multi-head spiral tucker normally, and when fluid product, filling device normally has the cylinder manipulating nozzles eductor of section, and making does not have on the base net near drop arrival chamber.This pollution of base net can suppress the excellent sealing of base net and upper wire or cover net subsequently.So far, padding does not also allow to stride across so multi-orbit this filling speed, prevents the compartment of multiple compartment pouch to be filled in so short time gap.

By non-limiting example, figure 27 illustrates the water-soluble bag 60 of many compartments with three compartments 60a, 60b, 60c.Exemplified with the method for shaping and filling bag 60 successively in Figure 28 and Figure 29.
With reference to Figure 28 and 29, former 61 comprises the chamber 62 with three sunk area 62a, 62b, the 62cs corresponding with compartment 60a, 60b, 60c of bag 60.Base net 63 in the 62a of region by shaping to be formed for the open-bag of compartment 60a or open containers.Then such as compartment 60a is filled with powder or particle by belt feeder 64.Feeder 64 can have scraper 66 to prevent the excessive filling of compartment 60a.Subsequently, base net 63 in the 62b of region by shaping to be formed for the open-bag of compartment 60b or open containers.Then such as compartment 60b is filled with powder or particle by belt feeder 64.Finally, in base net 63 to region 62c by shaping to be formed for the open-bag of compartment 60c or open containers.Then such as compartment 60c is filled with fluid or gel by nozzle material-feeding device 65.Use any above-described method and machine, shaping and that fill compartment 60a, 60b, 60c are closed by upper wire or cover net (not shown) and are sealed subsequently successively.
By shaping and fill successively, can be shaping and fill open-bag or open containers to form compartment in base net, this compartment in plan view on the direct of travel netted each other " overlapping ".Like this, the multiple compartment pouch comprising overlapping compartment can use method that is shaping and that fill successively described herein to manufacture, and the conventional approach that shaping compartment carries out filling subsequently simultaneously can not be used to manufacture owing to filling restriction.Said method may be used for any design of multiple compartment pouch.
Shaping base net 63 can be realized by diverse ways successively.A kind of method comprises each that vacuum put on successively in sunk area 62a, 62b, the 62c in chamber 62.Preferably, shaping and fill base net 63 each region in keep vacuum until bag 60 is discharged from former 61.Shaping and fill and provide greater room, the advantage of longer filling time successively, be therefore easy to fill the powder or particle that freely do not flow out from filling head.
Can come in various ways to provide vacuum feed to chamber 62 successively.Usually, vacuum controlled mechanical means is preferred, because its ratio is as more reliable potentially in the electric approach needing electric rotating to connect.Describe the vacuum feed that arranges for shaping base net 63 successively to form two kinds of methods of the open-bag corresponding with compartment 60a, 60b, 60c of bag 60 or open containers below with reference to Figure 30 with Figure 31, but those skilled in the art also it is contemplated that other method.
In Figure 30, use the vacuum bed device being used for shaping base net 63 successively, this vacuum bed device comprises three vacuum tanks 66a, 66b, 66c, and each vacuum that wherein each groove 66a, 66b, 66c control three sunk areas 62a, 62b, 62c respectively starts and terminates.Groove 66a, 66b, 66c there is different length and be constructed to make the halt point of all sunk area 62a, 62b, 62c identical so as from chamber 62 release bag.First groove 66a has actuation point the earliest, is the second groove 66b subsequently, is finally the 3rd groove 66c.Like this, first vacuum is applied to region 62a by vacuum tank 66a, and base net 63 can be only pulled in the 62a of region to form the open-bag corresponding with the compartment 60a that can be filled subsequently or open containers.When the vacuum of retaining zone 62a, then by vacuum tank 66b, vacuum is applied to region 62b, base net 63 can be drawn in second area 62b to form the open-bag corresponding with the compartment 60b that can be filled subsequently or open containers.At retaining zone 62a, during the vacuum of 62b, then by groove 66c, vacuum being applied to region 62c makes base net 63 can be drawn in the 62c of region, to form the open-bag corresponding with the compartment 60c that can be filled subsequently or open containers ... when all bags or container are all by shaping and filling, cover net (not shown) can be adhered to base net 63 with closed and sealed compartments, to form multiple compartment pouch 60 around open-bag or open containers.Bag 60 can be separated from combinational network subsequently, the vacuum feed being supplied to all three sunk areas is released, and or fallen by gravity or pass through to use pressurized air discharge or the combination by both, bag is discharged on suitable transfer system from the chamber 62 of rotatable former.
In Figure 31, use the vacuum valve device being used for shaping base net 63 successively, this vacuum valve device comprises three vacuum valves 67a, 67b, 67c, and wherein, each in valve 67a, 67b, 67c controls beginning and the end of the vacuum of each in three sunk areas 62a, 62b, 62c respectively.Each valve 67a, 67b, 67c are by mechanically controlling with actuator 68a, 68b, the 69c of straight cam 69a, 69b, 69c co-operate be arranged on below valve.Cam 69a, 69b, 69c have different length and are configured such that the halt point for all sunk area 62a, 62b, 62c is identical, so that from chamber 62 release bag.First cam 69a is the longest, and be then the second cam 69b, the 3rd cam 69c is the shortest.In this way, first vacuum valve 67 is activated and vacuum to be applied to region 62a, base net 63 can be only pulled in the 62a of region to form the open-bag corresponding with the compartment 60a that can be filled subsequently or open containers.When the vacuum of retaining zone 62a, vacuum valve 67b is then activated and makes base net 63 can be pulled in second area 62b vacuum to be applied to region 62b, the open-bag corresponding with the compartment 60b formed with can be filled subsequently or open containers.When the vacuum of retaining zone 62a, 62b, vacuum valve 67c is activated that vacuum is applied to region 62c, make base net 63 can be pulled in the 62c of region, to form the open-bag corresponding with the compartment 60c that can be filled subsequently or open containers ... when all bags or container are by shaping and filling, cover net (not shown) can be adhered to base net 63 to close with sealed compartments to form multiple compartment pouch 60 around open-bag or open containers.Bag 60 can be separated from combinational network subsequently, the vacuum being supplied to all three sunk areas is released, and or fallen by gravity or pass through to use pressurized air discharge or the combination by both, bag can be discharged on suitable transfer system from the chamber 62 of rotatable former.
In the fig. 31 arrangement, connect for the initial vacuum to valve group 70 vacuum manifold needing simple vacuum bed or some kinds.But cam 69a, 69b, 69c can be configured to adjustable, to change vacuum starting point and/or vacuum end point, to change valve timing.Such as cam 69a, 69b, 69c can be made up of (such as, the dovetail shape) two pieces that can adjust length.This adjustment can long-rangely realize.Compared with the setting of Figure 30, this can allow the timing of easier regulating valve, and vacuum bed must be removed or replaced to change length by the vacuum bed with different length groove or groove otch and reequiped seat in fig. 30.
Other advantage of the layout of Figure 31 is the vacuum line that only there is the valve group of going to valve 67a, 67b, 67c for each of sunk area 62a, 62b, 62c.In the layout of Figure 30, need independent circuit from vacuum bed to each sunk area 62a, 62b, 62c.
