Description
The present invention relates to the liquid dispensing bag and the quantitative chamber forming jig of proportioning device for liquid, it can be when batching be carried out to bag in the quantitative liquid of perfusion distribute and can not enter air and bacterium, thereby can in considerable time, keep the quality stipulated.
Past, with the liquid dispenser of beverage ingredient in the cup or the liquid charging stock feedway of cup type automatic vending machine, as coffee, tea, oolong tea and similarly easily oxidized and by the situation of the faintly acid beverage of bacterial infection or neutral beverage under, a kind of container that is called as bag in the box is arranged, be covered with the sack that one deck has high vapor barrier properties in carton, beverage is perfused in the container under aseptic condition in factory.Even because also long preservation at normal temperatures of the easily oxidized and rotten beverage of this arrangement.Reduce the expense of transportation distribution aspect.
But in proportioning device for liquid such as cup type automatic vending machine or liquid dispenser, liquid is in a minute timing at least, and air can directly enter container.So oxidation those energy corruption or easy and rotten neutral beverage can only short-term preservation a period of times.Thereby even beverage still can have problems by perfusion under the aseptic condition in factory, after beverage was transported to proportioning device for liquid, oxidation and metamorphic process made the difficult quality of regulation keep.Particularly the coffee of the just easy oxidation of those ingresss of air, tea, oolong tea or similar beverage always can not keep high quality in the proportioning device for liquid of routine.For proportioning device for liquid, also should not on amount, provide beverage bit by bit.In addition, in the proportioning device for liquid of routine, because liquid by fixing dated being filled in the cup, is annotated and chewed easily contaminated and drawn relevant hygienic issues.
As solution to the problems described above, the inventor once advised a kind of quantitative ingredient sack partly that has in the past, and it can be connected on the liquid quantitative feedway so that directly distribute quantitative liquid (Japan special permission communique No.6-293348) from bag.This band quantitative ingredient sack partly has the quantitative ingredient bag part that is used to store the liquid storage bag part of liquid and is used to measure and store a dosage that will be prepared burden, can not contact the proportioner miscellaneous part by the quantitative manner batching at the in one's duty liquid of proportion bag portion, it can prevent reliably that air enters into the liquid storage bag when batching, thereby can carry out the batching of neutral beverage in a small amount for a long time.Yet, since the liquid storage bag partly and between the quantitative ingredient bag part formed pouring out (or streamer) partly narrow on width, be distorted easily or bend, and be connected on the proportioning device for liquid trouble.In addition, pour out the part face the wall and meditate and rear wall closely stick together sometimes, so that pour out the part be difficult for open-minded.Also have, be connected under the state of proportioning device for liquid when pouring out part, because the difference of liquid capacity causes the difference of fluid pressure, so that it is inhomogeneous to flow to the quantitative effusion time appearance of quantitative bag part.What is more, and owing to the difference of liquid viscosity forms the difference of state under the flow of liquid, but in above-mentioned suggestion, the width that pours out the flow channel of part is constant.So the width of the flow channel of the contained class of liquids of foundation can not be regulated in order to keep the best state that pours out.
The sack with quantitative ingredient part of suggestion once before an object of the present invention is further to improve, and provide a kind of liquid dispensing bag that is used for proportioning device for liquid, in this proportioning device for liquid, though can supply very easily oxidation and rotten interior dress solution such as neutral beverage, and can one long-time in the maintenance certain quality.No matter whether the liquid in the liquid storage bag changes on capacity, proportioning device for liquid can both be prepared burden by quantitative manner reliably,, it can not produce the distortion of pouring out part or contact is irrelevant with it, and can carry out the batching of quantitative liquid satisfactorily.
Another object of the present invention is that a certain amount of chamber forming jig is provided in the liquid quantitative proportioner, and it can regulate the width that the liquid proportion bag pours out the flow channel of part rightly, and keeps the state that pours out an of the best according to the kind total energy of contained liquid.
In order to obtain aforesaid purpose, liquid dispensing bag of the present invention includes a pocket portion, it is made of facing the wall and meditating of being made up of the flexible material of high vapor barrier properties and rear wall, delivery pipe (runner) part with an extension, wherein this is faced the wall and meditated and rear wall stretches out from the bottom of this pocket portion in the mode that extends, and its characteristics are that have an integral solder above-mentioned faced the wall and meditated and rear wall will constitute near the position the bottom, pocket portion center towards the separated flow channel separated region of the flow channel of this pocket portion bottom.
Reasonablely be, have that be welded into above-mentioned faced the wall and meditated and the pressure control zone of rear wall constitutes above above-mentioned flow channel separated region, one adjustment hole is formed in the pressure control zone, so liquid always can be assigned to quantitative bag part under the constant compression force substantially.Also have, face the wall and meditate and rear wall between prevent that the contact that contacts from avoiding the vicinity or the contiguous of delivery pipe of the central flows passage that part is formed centrally to constitute in above-mentioned flow channel separated region, to open the central flows passage reliably.
The flow channel separated region can be by having at least one pair of ordinate and a weld part that forms the knock hole of weld zone constitutes, also can only constitute by at least one pair of knock hole that forms weld zone, this weld zone with in the central the part in a knock hole form.Be preferably, the flow channel separated region constitutes with knock hole, can realize the accurate installation to proportioning device for liquid like this.Narrow, an auxiliary weld zone forms above the flow channel separated region, so as be installed to liquid supplying apparatus go forward to annotate liquid that can not in the storage bag part flow into flow channel form the zone and quantitatively bag partly in.

Example 1
Fig. 1 is the front elevation of first example of liquid dispensing bag according to the present invention.Liquid dispensing bag 1 of the present invention comprises and is used for storing therein the pocket portion 2 of liquid, it constitutes closed state by the peripheral part 4 usefulness heat-sealing methods of facing the wall and meditating of forming of multilayered film material and rear wall, this membraneous material is a material high vapor barrier properties and that have certain flexibility, for example, polyethylene/adhesive linkage/isovaline phenolphthalein (eval)/adhesive linkage/polyethylene, with a microscler batching part 3, wherein face the wall and meditate and rear wall stretches out from the bottom of pocket portion in the mode of extending.
Position in approaching central part bottom from pocket portion 2 constitutes flow channel separated region 5, is used for the downward flow channel of pocket portion is separated into three flow channels.This flow channel separated region 5 provides vertical route 7,7, it by parallel peripheral around longitudinal centerline, form with a fixing interval integral solder antetheca and rear wall.In addition, the upside route 8,8 that extends mutually of the upper end along bag lateral edges direction from vertical route 7,7 and all face the wall and meditate and rear wall and forming with welding integrally along the downside route 9,9 that bag lateral edges direction is extended mutually from the lower end of vertical route 7,7.In this way, formed central flows path 10 forms at approaching lower position from the pocket portion middle part between vertical route 7,7, and side line on the both sides farthest and the bag lateral edges between formed lateral flow channels 11,12, constituted and comprised the flow channel separated region that adds up to three flow channels.
As mentioned above, the flow channel separated region is installed in the state that lower position, the bag at bag middle part be installed on the proportioning device for liquid and is illustrated later on, quantitative chamber forming jig is connected to flow channel separated region 5, so that form storage bag part 15 respectively in the above and form quantitatively bag part 16 below.
In the liquid dispensing bag in this example, inside has faces the wall and meditates and upper position and that bonding pressure control zone 13 thereon, rear wall circumferential ground is formed at the central flows path 10 extends through and faces the wall and meditates and the adjustment hole 14 of rear wall is formed at the middle part in pressure control zone 13, so that regulate the fluid pressure that flows to the central flows passage.Be formed with two fixed orifices 17 in upper-outer circumference part 2,17, in order to top fixing and the support bag, by face the wall and meditate and the knock hole 18 that stretches of rear wall weld be formed at flow channel separated region 5 last side line 8,8 below so that the flow channel separated region and quantitatively bag partly can be installed on the proportioning device for liquid reliably.
The filler opening of being made by plastic material with capping 19 integrally is installed on the facing the wall and meditating of storage bag part, so that liquid can be annotated by filler opening, certainly, if liquid is annotated and after filling the opening of upper edge is sealed from the opening of the upper edge of pocket portion, then aforesaid filler opening does not just need, as shown in the Fig. 4 that will illustrate afterwards.
In addition, in this example, similar two wire contact avoids part 20,20 to constitute along the middle part of facing the wall and meditating of central flows path 10 inlet portion.This contact is avoided partly making to face the wall and meditate contacting in face with rear wall, and wherein facing the wall and meditating faces the mutually different rear wall of surface configuration.In this example, only on facing the wall and meditating, make impression, the surface configuration of facing the wall and meditating with change.Method as changing surface configuration can adopt other the whole bag of tricks that are different from impression to make a surface or two surfaces make coarse surface.Batching part 3 also is equipped with the contact that is shaped on impression on facing the wall and meditating similarly and avoids device 21, and 21 ' contacts with the position, place of dispense valve preventing, the situation that dispense valve is installed on the fluid Supplying apparatus will illustrate below.
In above-mentioned liquid dispensing bag 1, when running condition not, batching part 3 be from the outside shown in dotted line 22 with a detouchable bearing pin or similarly in addition part oppress its end that is close to it closed, to prevent the flow of liquid part of advancing to prepare burden.In this state, when bag was filled with liquid in factory, liquid distribution was in the quantitative bag part 16 of storage bag part 15, flow channel separated region 5 and pocket portion, and predetermined amounts is annotated.So, when as the distribution phase in when transportation, the flow channel separated region is difficult for being distorted and bend and tearing open, Comparatively speaking bag of the present invention is unusual easy to handle with conventional bag.
The liquid dispensing bag 1 of full of liquid can install and fix hole 17 with two, 17 are fixed on the preposition, adjustment hole 14 and be formed on two knock holees 18 in the stopping projection 72 on the maintenance seat 71 of liquid quantitative proportioner 70,18, one stopping projection 73 and the fixedly projection (not shown) that is contained in corresponding to the flow channel separated region are shown in Fig. 7 respectively, and are installed in exactly on as shown in Figure 7 the liquid quantitative proportioner.Shown in shade line, the flow channel separated region is owing to oppress the method for side flow passages with the quantitative chamber forming jig 30,30 of liquid quantitative proportioner, except that the central flows path 10, be complete closed, 16 of storage bag part 15 and quantitative bag parts are linked up by the central flows passage.Between the quantitative chamber forming jig 30 and 30 is adjustable at interval, and in graphic example, this quantitative chamber forming jig 30,30 is in from vertical line 7, thus near 7 the side and the width that is positioned at its central flows path 10 can regulate.Under low-viscosity internal solution situation, the width shown in the central flows passage is comparable is transferred narrowlyer.
Under this situation, be contained in liquid stripper plate 31 (in Fig. 2, the dotting) motion on the liquid quantitative proportioner, also push the quantitative bag part that faces toward the liquid stripper plate so that between liquid stripper plate and adapter plate, form a fixing space, quantitatively the bag part is extruded, and the liquid of the surplus in quantitative bag part is extruded to the storage bag part, so that a quantitative liquid is store in quantitative bag part, finishes so adjust.
Under the liquid dispensing bag is installed in situation on the proportioning device for liquid, pour out on the ground location that (or beam) valve 32 (Fig. 2) and dispense valve 33 be in central flows path 10 and batching part 3 respectively.Shown in the arrow among Fig. 7 74 and 75, pour out valve or dispense valve and be subjected to a suitable actuating unit at place, right angle and handle and move with respect to central flows path 10 and flow part 3, make it to open or close central flows passage or batching part.After the adjustment of liquid dispensing bag finished, the lower end of batching part was cut off and removes so that open ingredients mouth, finishes the dead work of batching.
As mentioned above, after the adjustment of liquid dispensing bag 1 and dead work were finished, certain amount of fluid was stored in the quantitative bag part 16.So when the suitable actuating unit of dispense valve 33 usefulness unclamped the pressure of ingredients mouth, ingredients mouth was opened so that the liquid in quantitative bag part begins downward outflow.
Then, 31 extruding of liquid stripper plate are bag part 16 quantitatively, till liquid can be prepared burden satisfactorily and to the last do not had remaining liquid to stay in the bag, when batching finishes, dispense valve 33 at first forward, pouring out valve 32 then steps back, liquid stripper plate 31 is got back to its initial position, in initial position, one predetermined gap is formed between stripper plate and the adapter plate, liquid pours out by the central flows path 10 from storage bag part 15, so one give quantitative liquid and pour out quantitative bag partly in 16, prepares to do batching next time.
Foregoing program, quantitative liquid can need not contact proportioner from liquid dispensing bag 1 annex is injected in the cup 76.In the aforesaid blending process of this example, because the pressure control zone constitutes above the flow channel separated region, liquid in the storage bag part is divided into two parts, to reduce the pressure of liquid effects to the central flows passage, so, even under the situation that amount of liquid changes in the storage bag part, liquid can pour out downwards under constant compression force in the quantitative bag part.Moreover because the pressure control zone constitutes with adjustment hole, it keeps the connection that is connected protuberance with proportioner, and it is constant that the distance from the pressure control zone to the central flows passage always can keep.Even the residual liquid quantity in the storage bag reduces, liquid can be prepared burden under pressure control cooperates satisfactorily.More have,, even central flows passage width and ingredients mouth narrow down, can not contact between them, and when opening of valves, open smoothly, so that reliably liquid is prepared burden because contact avoids device to form in central flows passage and batching part.
In order to confirm the pressure control in the liquid dispensing bag of the present invention and the work and the effect of adjustment hole, carry out following experiment.
As an example of the present invention, the liquid dispensing bag of 3 liters of capacity is processed to shape as shown in Figure 1.Example as a comparison be processed into do not have pressure control zone and an adjustment hole but the shape liquid dispensing bag identical with capacity.Corresponding two sacks all are full of 3 liters water, and are installed on the proportioning device for liquid, so that the water of 30 grams of preparing burden at every turn, all water finishes with 100 batchings.Repeat 100 times batching and each dosage of measuring.In proportioning device for liquid, the adjustment angle of storage bag part is adjusted to 13 °.
As the result of this example laboratory, the result who is obtained as shown in Figure 5.And the result who is obtained under the comparison example situation as shown in Figure 6.Curve is obviously found out from figure, under the situation of example of the present invention, carried out 90 times batching after, dosage is more than minimizing slightly, but to the last the 100th time, the liquid of dispensing specified amount substantially.Batching is accomplished to once last, not waste.In the experiment of this example, average dosage is 29.542 grams, and its standard deviation is 0.39.
On the other hand, in Comparative Examples, almost identical with sample result of the present invention up to 90 times batchings.But, after 90 times, produce inhomogeneous greatly and can not carry out quantitative ingredient.So, in the proportion bag of Comparative Examples, just should finish carrying out 99 batching backs, also remain this moment in bag a large amount of liquid, so a problem that puts forward is this left liquid wrist-off.In the situation of Comparative Examples, average injection allocation amount is that 28.352 grams and standard deviation are 3.82.Hence one can see that, and its degree of irregularity is very big.
Confirm that from result of upper experiment the pressure control zone that is provided and the measure of adjustment hole have extremely significantly effect on the fixed supply of liquid, particularly the fixed supply when the remaining liq in the liquid dispensing bag reduces is all the more so.
In addition, simple in structure and valve opening and closing reliably.Simple to operate and do not need a twist of the wrist just can carry out liquid quantitative batching reliably.Also have, the part such as notes are chewed need not sterilize and safeguard, maintain and manage easily.
Example 2
Shown in Figure 3 is second example of liquid dispensing bag of the present invention, wherein still be denoted by the same reference numerals to preceding real complete those similar parts, and its detailed explanation is omitted.In this example, in liquid dispensing bag 40, the bottom of storage bag part 41 is tapered, constitutes flow channel separated region 42 and quantitative bag part 43 in its lower end.In this example, this flow channel separated region constitutes with the weldering body 44,44 that a pair of knock hole forms, and faces the wall and meditates and rear wall is welded in wherein, and knock hole 45,45 is formed in its core.So, in this example, flow channel is separated into three flow channels with the weldering body that a pair of knock hole forms, the central flows passage that forms is wideer than the flow channel of both sides, so that in quantitative ingredient, the scope of regulating the flow channel width with the quantitative chamber forming jig of proportioner is increased the variation that adapts to internal solution.
Moreover in this example, this storage bag part is formed with an auxiliary weld zone 25 in its underpart, faces the wall and meditates and welds on it with the back wall broad ways is auxiliary.Auxiliary weld zone 25 is used for preventing that the solution that is contained in the storage bag part from flowing in flow channel shaped region and the quantitative bag part, till when the former is installed on the fluid Supplying apparatus, auxiliary weld zone, fractures during extruding storage bag part under a predetermined pressure so that need only have at the disruption characteristic of frangibility but can install on fluid Supplying apparatus time not the under the normal allocation supply status as auxiliary welding.
As result of experiment, satisfying under the above-mentioned condition, the disruption characteristic scope of auxiliary weld zone is better at 100 to 500 gram force (gf)/15 mm wides, and is better in the scope of 15 to 400 gram forces/15 mm wides.
In liquid dispensing bag of the present invention, its side welds, so that quantitatively the interior bottom of bag part 43 is downward-sloping hypotenuses 46,46 as shown in the figure, slightly be the circumferential rising edge 47 that circumferential rises, 47 in the formation of the end of hypotenuse, and this hypotenuse links to each other with the intake section of ingredients mouth by circumferential rising edge 47,47.With this device result of experiment repeatedly, find that the shape of being mentioned just now can prepare burden to liquid satisfactorily, be not touched or bend and ingredients mouth 48 does not take place.Confirmed to adopt aforesaid shape liquid to carry out the most level and smooth batching and ingredients mouth do not occur and be touched or bend, and irrelevant with internal solution content.Particularly, when the batching beginning a kind of like this phenomenon takes place sometimes, because the unexpected variation of pressure, the inlet that flows out part bends.But, the complete obiteration after the measure of adopting aforementioned shapes of this said phenomenon.
As identical reason, in this example, play the top edge shape of quantitative chamber forming jig 50 of the partially-formed effect of batching of quantitative cavity segment in the certain amount of fluid in batching, be similar to proportion bag quantitatively the lower edge of bag part constitute.That is, the quantitative chamber forming jig 50 in this example is, its upside has a downward-sloping limit 52, and its distal-most end is that the rise limit 51 of a circle and the distal-most end that rises limit 51 are a vertical edges 53, with the passage width of the central flows passage of the liquid dispensing bag of making decision.Because the formation of above-mentioned quantitative chamber forming jig, liquid can flow to quantitative cavity segment satisfactorily downwards.
Quantitative chamber forming jig 50 is at adjustable ground on the interval and closely be installed on the proportioning device for liquid (not shown).This interval can be by being regulated and set by the viscosity of batching liquid.
Example 3
Fig. 4 represents the 3rd example of liquid dispensing bag of the present invention, and those wherein similar to above-mentioned example parts still are denoted by the same reference numerals, and its detailed explanation is omitted.
Liquid dispensing bag 60 in this example is similar to second example basically except that indicating in this example, and filler opening is cancelled, and after quilt was annotated with interior dress solution in filling factory, the top edge 61 of bag was sealed and sealed.At this moment, do not provide pressure control zone 13 and adjustment hole 14.It is that the size that depends on bag, the kind of interior dress solution and the pressure control zone and the adjustment hole that are installed to the state on the device need be provided because the batching of a fixed amount can be finished satisfactorily that pressure control zone and adjustment hole are not provided in this example.
Moreover, in this example, be rectangle substantially the bag four limits be welded into, form the taper weld zone 63 of storage bag part 62 bottoms, 63 portion's formation within it, the lower end of taper weld zone is made weld zone 66,66 longitudinally continuously, forms a mobile territory, channel separation area 64 and a certain amount of bag part 65.
The a pair of knock hole that is arranged in the flow channel separated region 64 of label 67,67 expressions.In this example, because 64 of this flow channel separated regions provide a single flow channel corresponding to the central flows passage, quantitative bag supply is also become possibility without anchor clamps.Moreover because the relative broad of formation of central flows passage, liquid can pour out quantitative bag part satisfactorily and need not provide contact to avoid part.Particularly, in this example, whole bag is rectangular, and its underpart is identical with its upper width, so its underpart can not be twisted and the transportation processing convenience.Be set on the proportioning device for liquid and also be easy to.
The different instances of liquid dispensing bag of the present invention is described in front, should be pointed out that the present invention is not limited to top several examples, can do some variations in design.For example, in above-mentioned example, pocket portion is being rectangular in shape, and what indicate is the shape that can use other.Moreover, in first and the 3rd example, do not form auxilliary picture weld zone, do not form auxiliary weld zone like that but can be similar to second example yet.In second example, there is no need must be with assisting weld zone conversely speaking.Moreover, can the pressure control zone be set in center near the central flows channel part, still, if necessary, a plurality of pressure controls zone can also there is no need to be used on the 3rd example along constituting on the width interval.
What is more, and in above-mentioned example, quantitatively the bag part is installed on the liquid quantitative proportioner in order to allow certain amount of fluid to flow in the bag of preparing burden by a certain amount of liquid.Yet liquid dispensing bag of the present invention not only can be used for aforesaid application process, does not contact other proportioning device for liquid of bag interior liquid when also can be used for preparing burden.For example, in first example, the dispense valve of installing on the batching part is undertaken under the situation of suitable quantitative ingredient by time meter or manual control, and three flow channels of all in the flow channel separated region are all opened, and batching is carried out in this state.In this case, thus pocket portion is provided with the fluid pressure that three flow channel separated regions and pressure control zone affact the batching part to be conditioned to keep batching pressure constant substantially.Even under the state that interior dress solution is full up, still can prepare burden satisfactorily.
In above-mentioned example, territory, quantitative chamber forming jig contact flow channel separation area, but be not limited thereto.Can change to some extent, quantitative chamber forming jig is in the part that is lower than the flow channel separated region and contacts, so that quantitatively the chamber flow channel is under the central flows passage.Under the sort of situation, contact avoids part can be formed at flow channel place, quantitative chamber haply.
As mentioned above, according to liquid dispensing bag of the present invention, under proportion bag was not installed to situation on the proportioning device for liquid, liquid was full of, and was distributed in the whole inner chamber of the quantitative bag part of storage bag part, flow channel separated region and pocket portion.So the flow channel separated region can simply not be twisted or bend for example transporting distribution phase.Liquid dispensing bag of the present invention is very easy to handle for conventional bag, carries and is installed on the proportioning device for liquid easily.Under proportion bag was installed to situation on the liquid quantitative proportioner, the flow channel separated region was closed in wing passage fully, only stayed the central flows passage and opened, and storage bag partial sum quantitatively bag part can only be linked up by centre gangway.In this state, constituted by the liquid stripper plate that is installed on the liquid quantitative proportioner,, so that determined that the liquid of deal can be stored can implement quantitative ingredient so the liquid measure in quantitative bag part is controlled with respect to the fixed interval (FI) of adapter plate.
In addition, contact avoid part be formed on the core of central flows passage or importation near, even pour out the narrow width of partial sum ingredients mouth, they do not contact, and they are opened smoothly when opening of valves, carry out liquid dispensing reliably.Moreover according to the present invention, the quantitative bag part of liquid dispensing bag is not used under the situation of metering, and the flow channel of all flow channel separated regions is all opened use.In this case, even carry out pressure control in the flow channel separated region, under the cooperation in pressure control zone, the batching pressure at ingredients mouth place still can keep constant substantially, and can finish batching satisfactorily.
Also have, in the quantitative ingredient process, pour out mouthful quantitatively that a bag flow passage width partly is not specific, and the flow passage width can be regulated under sack is installed in state on the liquid flow distribution apparatus.So the flow passage width that pours out mouth can suitably be regulated according to the viscosity or the similar parameter of liquid, so that liquid always can pour out under top condition in the quantitative bag part.As a result of, this quantitative performance can be guaranteed more reliably.
In the quantitative chamber forming mould of proportioning device for liquid, its upper limb constitutes a downward-sloping hypotenuse, the end of this hypotenuse constitute a circular rising edge that upwards rises slightly circularly and have one by established circular rising edge in order to the vertical edges of formation delivery pipe.So,, pour out mouth when entering in the quantitative bag part and can not bent when liquid pours out, and always can finish batching work satisfactorily according to the reason identical with the shape of bag lower edge.
