Detailed description of the invention
In Fig. 1, Fig. 6, Fig. 7, numeral 100 is overall to be represented for from being contained in interchangeable capsuleInfusion product in 1 prepares the preferred embodiment of (according to the present invention) of the system of beverage.
System 100 includes: interchangeable capsule 1(its will be described in more detail below), andFor preparing the osmotic engine 150 of brewed thing.
Osmotic engine 150 includes again: be suitable to accommodate container 160(Fig. 1 of interchangeable capsule 1), andDistributor 170 for pressure fluid (water particularly pressurizeed).
Referring in particular to Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 8, returning to system 100Before the detailed description of operation, interchangeable capsule 1 be will be described in further detail.
By way of parenthesis, in the present context, it is necessary to word " interchangeable capsule " is interpreted as discardable classType, be generally used for nonrecoverable encapsulation, it means that, brewed be contained in encapsulationAfter pelletized product, this encapsulation is disposed off (all used product infused together with its insideProduct), it is removed from the container of osmotic engine.It is apparent that once first " interchangeable capsule " byUsing and process, it is just generally replaced by the second encapsulation of same type, and this second encapsulation replaces infiltrationThe first encapsulation in the special container of machine.
Encapsulation 1(Fig. 5) include the cup-shaped structure 2 that is made for a truncated cone shape body, its by sidewall 3,The circular crown 5 of diapire 4 peace limits, and this flat circular crown is from the top edge of sidewall 3 radiallyExtend.As we shall see, cup-shaped structure 2 is supported on osmotic engine by this flat circular crown 5In the special container 160 of 150 (Fig. 1) (seeing below).
Additionally, three longitudinal rib 3a arranged with 120 ° of equal intervals prolong towards the inside of sidewall 3Stretch.As described in more detail below, these three flank 3a is used for reinforced sidewall 3, it addition, it is alsoIt is used for making the heat pressurization liquid stream in cup-shaped structure 2 itself disconnect, to make heat during impregnation stepWater more closely contacts with granular product infused.And, automatic fill with infusion productIn processing procedure, these three flank 3a is also used for avoiding the spontaneous stacking of encapsulation 1.In other words,These three flank 3a on the inwall of cup-shaped structure 2 prevents encapsulation 1 to be stacked on that at random and by accidentInside this.That is if it is not, if cup-shaped structure 2 can enter another cup-shaped structure randomlyThe inside of 2, then, it will the fault processing with all cup-shaped structure 2 of product infused occursAnd filling.
Cup-shaped structure 2 is made up of rigid plastic material or thermoset plastic material；Preferably, usedPlastic material be biodegradable type.
Encapsulation 1 farther includes lid 6, described closed with covers cup-shaped structure 2(Fig. 3, Fig. 4, figure5) free oral area, it is allowed to stay in cup-shaped structure 2 itself and (do not shown by brewed granular materialGo out) stay therein.As specifically shown in Fig. 5, lid 6 is arranged in circular crown 5Portion so that the top edge of sidewall 3 is positioned at the lower section of lid 6 itself.
In the specific embodiment shown in Fig. 3, Fig. 4, lid 6 has substantially circular shape.In use, lid 6 is contained in groove 6a circular, crown, in the upper zone of wall 3Territory obtains this groove.Lid 6 is also made up of rigid plastic material.
Illustrating in greater detail as in Fig. 8, the top of groove 6a includes edge 66, and it has annularShape, and inwardly stretch out towards the longitudinally asymmetric axis (Y) of cup-shaped structure 2.This edge 66Also it is made up of plastic material, thus is resiliently deformable, to allow to insert in groove 6a lid 6.During the step that lid 6 engages automatically with corresponding cup-shaped structure 2, described lid 6 is recessedThe bottom (on side) of groove 6a and edge 66(are on another side) between tensioning.It practice,When during (known type and unshowned) specified packet installation intermediate package encapsulation 1, thisEncapsulation 1 is by high acceleration, therefore, if lid 6 not tensioning between said elements, then willThere is lid 6 and the de-actual danger of corresponding cup-shaped structure 2, result can cause the product in packerThe undesirable spilling of product.
And, the most as shown in Figure 8, the bottom of groove 6a has the projection 31 of circle.LogicalCross known method, with the stuffing cup-shaped body of product 2 infused and in the foregoing manner with lid 6After closing described cup-shaped body 2, the method is only by the local melting of circular protrusions 31 (such as,Pass through ultrasound wave) continue, to obtain the clearly fastening of lid 6 and the bottom of groove 6a.
The inner face of lid 6 may be provided with any kind of filter (not shown) being suitable for demand.Especially, as known, this filter is elastically deformable.
Circular protrusions 31 can be continuous type or interrupt type, it means that, in latterIn situation, by circular segment, (such as, three offset relative to each other 120 ° to this circular protrusions 31Circular segment) composition.Figure 2 illustrates latter solution, wherein, each circle is convexPlay 31 to be arranged at flank 3a.
As also illustrated that in fig. 8, the lower surface of circular crown 5 is provided with sealing annular rib32, it has the gable most advanced and sophisticated with aplysia punctata.
Have been found that if sealing the sealing thickening part forming circular crown 5 at annular rib 32Point 33(Fig. 8), then, can realize about close relative to the container 180 of system 100 of encapsulation 1The optimum of envelope.As observed in fig. 8, it is distributed on two faces of circular crown 5This sealing reinforcement 33.
(particularly seeing Fig. 3, Fig. 4) in embodiment illustrated in the accompanying drawings, lid 6 has multiple valve7, described valve is arranged to allow to be released through the brewed drink mixed by hot water and formed with infusion productMaterial.
More particularly, valve 7 can be the first kind represented with 7a, or second represented with 7bType.Two types 7a, 7b is towards external opening (Fig. 4).
Such as, as it is shown in figure 1, relative to the symmetrical plane (ψ) of lid 6, valve 7a is positioned at valve 7bOpposite side on.In this way, under the influence of the effect that the water injected is applied, valve 7a, 7bAt least some of can open undoubtedly.
Having two kinds of this selection of valve 7a, 7b is by the packaging simplifying encapsulation 1 as much as possibleThe demand of machine (not shown) is determined.If it practice, all valves 7 are all 7a types,So during engaging with cup-shaped body 2, packer needs to be oriented lid 6.This will meaningTaste the obvious complexity of the packer of the encapsulation 1 including product (particularly in sensor rankOn).On the contrary, by using two kinds of valve 7a, 7b in identical lid 6, how will lidSon 6 is arranged in groove 6a the most unimportant.
Figure 7 illustrates the enlarged drawing of general valve 7a.
Still, identical situation is obviously also applied for valve 7b to valve 7a() there is corresponding cavity 8 HeCorresponding trap portion 9, trap portion 9 is hinged with the remainder of lid 6 by hinge 10 on sideAnd have on another side and run through otch 11.
(not shown) in one embodiment, has preferential striping, and it is separated by fluid under pressure,Rather than by running through otch 11 separately.
It practice, in the embodiment advised in the accompanying drawings, trap portion 9 is simply the bottom of cavity 8.
In use, it is intended to the pressure of the infusion product left from cup-shaped body 2 is executed on trap portion 9Power, makes described trap portion according to arrow (F1) (Fig. 7) around hinge 10 towards cup-shaped structure 2External rotating.
Especially, each trap portion 9 has rectangle plane and trapezoidal longitudinal cross section, in the feelings of valve 7aIn condition, fully extended in cup-shaped body 2, thus form corresponding cavity 8.
Advantageously, but not necessarily, by plastic material moulding process, valve 7 is madeForm as one relative to lid 6.
As being clearly shown that in Figure 5, bottom 4 includes annular hollow portion 12, and it is relative to cupThe longitudinally asymmetric axis (Y) of shape structure 2 is arranged in the position of symmetry.Towards cup-shaped structure 2Outside corresponding cannelure 13 is corresponding with annular hollow portion 12.
Additionally, bottom 4 has impression 14 at axis (Y) place.
Based on the demand of 4 suitable hardness bottom giving (especially because water itself have to be stood in bottom 4The reason of high pressure) and facilitate annular hollow portion 12 and the existence of impression 14.
As also illustrated that in Figure 5, have four valve 17(the most only it can be seen that one of them),Described four valves offset relative to each other 90 ° on the bottom of cannelure 13.
Each valve 17 has corresponding trap portion 18, and it passes through hinge (that is, by hinge on sideChain 19) hinged with the remainder of bottom 4, and be provided with on another side and run through otch 20.
In an embodiment (not shown), first block of data 50, having preferential striping, it is separated by fluid under pressure,Rather than by running through otch 20 separately.
The hot water distributed by distributor 170 applies power in trap portion 18 so that it is according to arrow(F2) (enlarged drawing in Fig. 5) is around hinge 19 towards the inner rotation of cup-shaped structure 2.
Especially, each trap portion 18 has the longitudinal cross-section of rectangle plane and substantial rectangular, andAnd, if compeled by the hydraulic pressure pressurizeed, then extend inside cup-shaped structure 2.
Advantageously, but not necessarily, by rigid plastic material moulding process, this is madeThe remainder of four valves 17 and diapire 4 forms as one, and thus with its of cup-shaped structure 2Remaining part is fractal to be integrally forming.
Now, we will be returned to the system 100 shown in Fig. 1, Fig. 6, Fig. 7.
The groove 165 of substantially cylindrical is arranged in the core of container 160, and is suitable to accommodateState the part of distributor 170.
Described distributor 170 includes again the service 171 of hot liquid and is at least partially contained inDistributor chamber 172 in groove 165.
Distributor chamber 172 is in fluid communication with service 171 by opening 173 on side, and separatelyIt is in fluid communication with cannelure 13 on side.Briefly, according to arrow (ARW), the hot water of pressurizationFlow through opening 173 and flow to cannelure 13 from service 171.
Distributor 170 farther includes each other in 120 ° of three pecker 180(arranged at Fig. 5In only it can be seen that one).In other words, pecker 180 composition is arranged at the use in multiple osmotic engineConventional apparatus in the bottom penetrating encapsulation 1.In use, pecker 180 is towards cup-shaped structure 2Bottom 4 move.
Otch 20 is not extended through, then the pressure of liquid is such if there is preferential striping,It makes preferential striping disconnect, and, (press as it has been described above, trap portion 18 rotates around hinge 19According to arrow (F2)), thus allow the hot water pressurizeed from cannelure 13 to the inside of cup-shaped structure 2Pass through.It is worthy of note, four valves 17 are all on the bottom of cannelure 13, in use,Pin 180 is positioned at the inside of this cannelure 13.
It practice, in the case of in being in control, pecker 180 will not penetrate the end by any wayPortion 4, but the only effect of pressure fluid by being distributed by distributor 170 makes trap portion 18 deform.
It is also worth noting that as it has been described above, have four valves 17, and there are three peckers 180.Therefore, can determine, at least two peckers 180 contact the work of (not promoting) at least two all the timePlate portion 18.
Therefore, pecker 180 the fact that to contact in the way of not promoting trap portion 18, a sideFace, it is allowed to regain useful space so that more granular material is brewed in cup-shaped structure 2,On the other hand, prevent from trap portion 18 can be perforated pin 180 itself shear and enter in infused liquid.If there is this phenomenon, i.e. if there is plastics or the metallic particles of suspension in infused liquid, thatThe most for certain, this granule will be taken in by client, brings obvious negative consequences.
With reference now to Fig. 7, change into paying close attention to the valve 7a, 7b on lid 6.
Within system 100, container 160 at top by the closed upper part element 190 of container 160Close.
As it is shown in fig. 7, the stream after thus defining infiltration between lid 6 and upper closure elements 190The collecting chamber 191 of body.In other words, all cup-shaped structure 2 is had passed completely through and from valve 7The osmotic fluid left accumulates in collecting chamber 191.It is worthy of note, there is not the machinery of valve 7Open element, be that the pressure of the water in cup-shaped structure 2 itself opens valve 7 itself.Stream in infiltrationUnder the bias of the pressure of body, from the beginning of detent position, valve 7 from the detent position of exit region move toThe open position of exit region, thus, when the fluid stream of infiltration interrupts, also it is maintained at this openingIn position.Therefore, the structure of lid 6 is for good and all changed.It is worthy of note, because in infiltrationAfter fluid stream interrupts, valve 7 also keeps in the open position, but owing to putting on the above-mentioned mistake of lid 6Filter (not shown) can stop passing through, so not having it partially towards all of outside of infusion productHis thing can flow out from cup-shaped structure 3.Owing to filter is made up of the material of elastically deformable, so,In the opening procedure of valve 7, but this filter can deform will not bore a hole.
Additionally, also illustrate that as in Fig. 7, by making height (H) classification of collecting chamber 191(graduate, scale division), it is possible to thus make the opening classification in the trap portion 19 of valve 7, thus,Hydraulic pressure in encapsulation 1 is equal, so that water itself is from valve 7 exit velocity stages.Pass throughChange height (H), can the most gradually change the time that water contacts with granular product infused.Balance of this persistency time therefore long enough must be made, good with allow granular product simultaneouslyGood the most brewed the rapidity of penetration operation will not be caused excessive infringement.
In use, once encapsulation 1 is inserted container 160, will pass through corresponding distributor 170This container 160 is made to move, as shown in Figure 1 relative to upper closure elements 190.The heat of pressurizationBeginning is flowed towards cannelure 13 and valve 17 by water from pipeline 171, and valve 17 is by by water itselfPressure effect and open.The hot water once pressurizeed enters cup-shaped structure 2, then it will start towards lidSon 6 flowing, does not have preferential streamline.Under the bias of the pressure of the fluid of infiltration, valve 17 is from enteringThe detent position of port area moves the open position to entrance area, thus, when in the fluid stream of infiltrationTime disconnected, also it is maintained in this open position.
Moreover it is preferred that but the most not necessarily, can include being positioned in interchangeable in valve 17Encapsulation 1 forms the introducing gap of the water of the basic tubular track of osmotic fluid, to promote water cup-shapedTurbulent flow is formed, to relate to granular material as much as possible in penetration operation in structure 2.Valve 17Produce multiply pressurized hot water, it is preferable that described pressurized hot water is directed relative to sidewall 3.This penetrateStream is guided by flank 3a, produces desired turbulent flow in cup-shaped structure 2.
The major advantage of said system is:
-significantly increase the amount of granular product in cup-shaped body；
-the persistency temporal scalability that hot water contacts can be made with granular product；
-actually it is completely eliminated the hot water preferential streamline in cup-shaped structure；And
-any danger that beverage pollute is completely eliminated, broken not from rupturing of bottom and/or lidSheet.
