Description

For from the infusion product being contained in interchangeable capsule Prepare the system of beverage

Technical field

The present invention relates to the system for preparing beverage from the infusion product being contained in interchangeable capsule. Additionally, the present invention relates to the interchangeable capsule being suitable to use in such systems.

Background technology

It is known that interchangeable capsule receiving granular product, such as, coffee, Fructus Hordei Vulgaris, milk powder, Folium Camelliae sinensis, Flos Chrysanthemi, etc..

It is commonly used for the cup that the interchangeable capsule of infusion product includes being made up of plastic material, at it Middle receiving infusion product, and be arranged for closing cup and also (can by plastic material or thin film To be porous) lid made.

When encapsulation is inserted be used for preparing in the infiltration room of the system of beverage time, by encapsulation itself The hot water of pressurization is injected in cup by multiple first holes formed on bottom.

Water mixes with the granular product in encapsulation, and, water by multiple second holes in bowl cover from Encapsulation itself flows out.

At European patent EP-B1-2134611(SARA LEE) in show of this system Example.

At EP-B1-2134611(SARA LEE) in suggestion solution in, be used for penetrate biography The perforation tips of system encapsulation will not penetrate the bottom of the encapsulation of the Types of Innovation advised in the above documents, Because the bottom of the encapsulation of described Types of Innovation is always located in giving distance from perforation tips, and, When the latter is in the position being fully drawn out, also it is so.Advise that solution that this is new is to avoid In bottom, occur that bigger center is pierced through, occur in bottom bigger center pierce through by needs Preferential streamline is formed in shot-like particle.It practice, think that the formation of this preferential streamline is rich for obtaining The brewed thing of fragrance is worthless, and on the contrary, rich aromatic brewed thing should be fully from be contained in can Exchange in the whole granular substance in encapsulation and extract.

Additionally, from EP-B1-2134611(SARA LEE), in order to avoid shape in brewed thing Becoming preferential streamline, its bottom that may result in encapsulation must be away from the container bottom accommodating encapsulation itself of machine Portion.By this way, perforation tips will not penetrate the whole intake section bottom encapsulation, on the contrary, meeting Make to inject current and surround this intake section completely.

But, at EP-B1-2134611(SARA LEE) in use solution have very Great shortcoming: in the case of container is equal, encapsulation must be shorter, to avoid tip.Therefore, This encapsulation is shorter, thus accommodates less infusion product.For this reason, the brewed thing obtained Not having too many fragrance, the product being not only because in encapsulation is less, but also because encapsulation is shorter, So the persistent period that water is in encapsulation is shorter, this fact substantially damages the matter of produced brewed thing Amount.

Summary of the invention

Therefore, it is an object of the invention to, manufacture a kind of do not have disadvantages mentioned above for from be contained in can be mutual Change the infusion product in encapsulation and prepare the system of beverage.

According to the present invention, thus produce a kind of for from the infusion product being contained in interchangeable capsule Prepare the system of beverage, described system as disclosed in claim 1 or be such as depending directly or indirectly on Disclosed in any claim of claim 1.

Additionally, it is another object of the invention to provide a kind of be suitably employed in said system interchangeable Inject encapsulation.

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 capsule Infusion 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), and For 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), and Distributor 170 for pressure fluid (water particularly pressurizeed).

Referring in particular to Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 8, returning to system 100 Before 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 class Type, be generally used for nonrecoverable encapsulation, it means that, brewed be contained in encapsulation After pelletized product, this encapsulation is disposed off (all used product infused together with its inside Product), it is removed from the container of osmotic engine.It is apparent that once first " interchangeable capsule " by Using and process, it is just generally replaced by the second encapsulation of same type, and this second encapsulation replaces infiltration The 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 radially Extend.As we shall see, cup-shaped structure 2 is supported on osmotic engine by this flat circular crown 5 In 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 3 Stretch.As described in more detail below, these three flank 3a is used for reinforced sidewall 3, it addition, it is also It is used for making the heat pressurization liquid stream in cup-shaped structure 2 itself disconnect, to make heat during impregnation step Water more closely contacts with granular product infused.And, automatic fill with infusion product In 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 accident Inside this.That is if it is not, if cup-shaped structure 2 can enter another cup-shaped structure randomly The inside of 2, then, it will the fault processing with all cup-shaped structure 2 of product infused occurs And filling.

Cup-shaped structure 2 is made up of rigid plastic material or thermoset plastic material；Preferably, used Plastic material be biodegradable type.

Encapsulation 1 farther includes lid 6, described closed with covers cup-shaped structure 2(Fig. 3, Fig. 4, figure 5) free oral area, it is allowed to stay in cup-shaped structure 2 itself and (do not shown by brewed granular material Go out) stay therein.As specifically shown in Fig. 5, lid 6 is arranged in circular crown 5 Portion 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 3 Territory 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 annular Shape, and inwardly stretch out towards the longitudinally asymmetric axis (Y) of cup-shaped structure 2.This edge 66 Also 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 recessed The 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, this Encapsulation 1 is by high acceleration, therefore, if lid 6 not tensioning between said elements, then will There is lid 6 and the de-actual danger of corresponding cup-shaped structure 2, result can cause the product in packer The undesirable spilling of product.

And, the most as shown in Figure 8, the bottom of groove 6a has the projection 31 of circle.Logical Cross known method, with the stuffing cup-shaped body of product 2 infused and in the foregoing manner with lid 6 After 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 latter In situation, by circular segment, (such as, three offset relative to each other 120 ° to this circular protrusions 31 Circular segment) composition.Figure 2 illustrates latter solution, wherein, each circle is convex Play 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 rib 32, 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 32 Point 33(Fig. 8), then, can realize about close relative to the container 180 of system 100 of encapsulation 1 The optimum of envelope.As observed in fig. 8, it is distributed on two faces of circular crown 5 This sealing reinforcement 33.

(particularly seeing Fig. 3, Fig. 4) in embodiment illustrated in the accompanying drawings, lid 6 has multiple valve 7, described valve is arranged to allow to be released through the brewed drink mixed by hot water and formed with infusion product Material.

More particularly, valve 7 can be the first kind represented with 7a, or second represented with 7b Type.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 7b Opposite side on.In this way, under the influence of the effect that the water injected is applied, valve 7a, 7b At 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 possible The 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 meaning Taste the obvious complexity of the packer of the encapsulation 1 including product (particularly in sensor rank On).On the contrary, by using two kinds of valve 7a, 7b in identical lid 6, how will lid Son 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 He Corresponding trap portion 9, trap portion 9 is hinged with the remainder of lid 6 by hinge 10 on side And 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 9 Power, makes described trap portion according to arrow (F1) (Fig. 7) around hinge 10 towards cup-shaped structure 2 External rotating.

Especially, each trap portion 9 has rectangle plane and trapezoidal longitudinal cross section, in the feelings of valve 7a In 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 made Form 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 cup The longitudinally asymmetric axis (Y) of shape structure 2 is arranged in the position of symmetry.Towards cup-shaped structure 2 Outside 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 4 The 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 side Chain 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, and And, 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 made The remainder of four valves 17 and diapire 4 forms as one, and thus with its of cup-shaped structure 2 Remaining 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 accommodate State the part of distributor 170.

Described distributor 170 includes again the service 171 of hot liquid and is at least partially contained in Distributor chamber 172 in groove 165.

Distributor chamber 172 is in fluid communication with service 171 by opening 173 on side, and separately It is in fluid communication with cannelure 13 on side.Briefly, according to arrow (ARW), the hot water of pressurization Flow 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. 5 In only it can be seen that one).In other words, pecker 180 composition is arranged at the use in multiple osmotic engine Conventional apparatus in the bottom penetrating encapsulation 1.In use, pecker 180 is towards cup-shaped structure 2 Bottom 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 19 According to arrow (F2)), thus allow the hot water pressurizeed from cannelure 13 to the inside of cup-shaped structure 2 Pass 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 way Portion 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 time Plate portion 18.

Therefore, pecker 180 the fact that to contact in the way of not promoting trap portion 18, a side Face, 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, that The 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 160 Close.

As it is shown in fig. 7, the stream after thus defining infiltration between lid 6 and upper closure elements 190 The collecting chamber 191 of body.In other words, all cup-shaped structure 2 is had passed completely through and from valve 7 The osmotic fluid left accumulates in collecting chamber 191.It is worthy of note, there is not the machinery of valve 7 Open element, be that the pressure of the water in cup-shaped structure 2 itself opens valve 7 itself.Stream in infiltration Under the bias of the pressure of body, from the beginning of detent position, valve 7 from the detent position of exit region move to The open position of exit region, thus, when the fluid stream of infiltration interrupts, also it is maintained at this opening In position.Therefore, the structure of lid 6 is for good and all changed.It is worthy of note, because in infiltration After fluid stream interrupts, valve 7 also keeps in the open position, but owing to putting on the above-mentioned mistake of lid 6 Filter (not shown) can stop passing through, so not having it partially towards all of outside of infusion product His 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 through Change 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 simultaneously Good 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 170 This container 160 is made to move, as shown in Figure 1 relative to upper closure elements 190.The heat of pressurization Beginning is flowed towards cannelure 13 and valve 17 by water from pipeline 171, and valve 17 is by by water itself Pressure effect and open.The hot water once pressurizeed enters cup-shaped structure 2, then it will start towards lid Son 6 flowing, does not have preferential streamline.Under the bias of the pressure of the fluid of infiltration, valve 17 is from entering The detent position of port area moves the open position to entrance area, thus, when in the fluid stream of infiltration Time 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 17 Encapsulation 1 forms the introducing gap of the water of the basic tubular track of osmotic fluid, to promote water cup-shaped Turbulent flow is formed, to relate to granular material as much as possible in penetration operation in structure 2.Valve 17 Produce multiply pressurized hot water, it is preferable that described pressurized hot water is directed relative to sidewall 3.This penetrate Stream 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 lid Sheet.
