Description

Container and device with such a container

The invention relates to a container according to the preamble of claim 1. The invention also relates to a device, in particular beverage machine, come in the sol ^¬ che container used.

In beverage machines, especially in coffee machines, disposable containers or disposable packaging, eg. In the form of capsules, which are closed by means of one or two films and which contain, for example, coffee or other substances, such as flavorings, in pulverulent or liquid form. These disposable containers are inserted into the beverage machine, which becomes the contents of the disposable container flues with a ^¬ sigkeit, z. As water, brought together and this preparation is then delivered as a finished drink. The used disposable container is then removed from the beverage machine and disposed of.

EP 0451980 Bl discloses a sealed Verpa ^¬ ckung one or more pulverulent, pasty or

contains liquid food preparation ingredients. An inlet opening feeds these ingredients with water. The finished preparation is provided by a floor area

Outlet nozzle discharged, which has a displaceable plug. To discharge the finished preparation, the bottom wall of the packaging consisting of a film in the region of the outlet nozzle is pierced by a machine-side connecting piece from below, which pushes the plug upwards against an intermediate wall after it has penetrated into the outlet nozzle. This interim ^¬ rule wall has provided a predetermined breaking lines

Wall section, which is broken by the stopper, whereby the preparation is released. This flows out of the packaging through a central through-channel in the plug and then down through the machine-side connection piece. This packaging has the disadvantage that the bottom-side outlet must be opened by the machine-side connecting piece, so that the connecting piece comes into contact with the finished preparation. In order to meet today's high hygienic requirements for such a device, it is necessary to clean this connector before inserting a new packaging every time.

The US 2004/0115317 AI describes a z. B. with Kaf ^¬ feepulver filled cartridge whose bottom wall from the inside

is pierced. Above the bottom wall, a cup-shaped intermediate bottom is arranged, which is referred to as inner piston and which is adapted to the inner dimensions of the cartridge. The powder is located between the intermediate bottom and the top wall of the cartridge. The intermediate bottom is provided with a discharge nozzle designed as a cutting element. If water with

Pressure is introduced through the top wall into the interior of the cartridge, the intermediate bottom is pressed down, wherein the cutting element pierces the bottom wall and the outlet is released.

Although this cartridge meets the hygienic requirements, but the functionality of the cartridge is not always guaranteed. In this embodiment, it is important that the water pressure and thus the pressure on the false bottom right at the beginning of the introduction is large enough so that the bottom wall can be pierced. A jamming of the movable intermediate floor can not be excluded in this case. Since the intermediate bottom has a plurality of passage openings, liquid can also penetrate into the intermediate space between the bottom wall and the intermediate bottom, whereby the pressure on the false floor after the beginning of the introduction process degraded relatively quickly and thus the bottom wall can not be reliably pierced.

From WO 2008/132571 capsules are known which contain a certain amount of a soluble beverage. The capsule has a cover sheet, which is pierced in the beverage machine by a connecting piece, on the one under pressure standing solution liquid such. As water, the interior of the capsule is supplied.

The capsule is essentially divided into four chambers. The supplied liquid is first in a

Introduced distribution chamber and fed from there to a storage chamber in which the amount of soluble beverage is. In this storage chamber, the releasable beverage mixes with the supplied liquid and the prepared beverage is ^{subsequently ¬} collected in a collection chamber, from where it is discharged through an opening in the bottom wall of the capsule.

In order to open the bottom wall, a displaceable perforator is arranged in a central chamber of the capsule, which is pressed by the connecting piece against the bottom wall, so that the ^¬ se tears.

Here, a arranged inside the perforator

Passage channel with the outlet opening of the collection chamber brought to coincide, so that the prepared liquid can be discharged from the capsule down.

However, this capsule has the disadvantage that complicated components are required to subdivide the various chambers. In order to be able to supply the liquid as evenly as possible to the storage chamber and to ensure homogeneous mixing in the latter, a distribution chamber arranged upstream of the storage chamber is required. This can not be ruled out that at the beginning of a part of the soluble beverage is discharged unmixed or with high concentration. The intended for homogenization collection chamber can not completely rule out this disadvantage.

It is an object of the invention to provide a container which is of simple construction, functions reliably and ensures a homogeneous end product. It is also an object of the invention to provide a device, in particular a beverage machine, in which such a container can be used.

This object is achieved with a container in which the adjusting element has a mixing chamber for mixing the liquid and the base product and in which the mixing chamber in Push-through position of the adjusting element with the chamber in Strö ^¬ mungsverbindung is.

The container is designed such that the liquid and the base product are combined only in the mixing chamber.

Under a container are both reusable containers and

Packages as well as disposable containers and packaging understood.

The laying of the mixing chamber in the adjusting element has the advantage that the base product located in the first chamber can be continuously fed to the liquid, resulting in a homogeneous end product. The mixing of base product and liquid, in particular the quantitative addition of the base product does not take place in the first chamber, where the base product is, but in a separate mixing chamber, which is connected downstream of the first chamber.

The arrangement of the mixing chamber in the adjusting element has the further advantage that the displaceability of the positioning element Ver ^¬ the mixing chamber for the base product only in

Time of use can be made accessible. The base product remains trapped in the first compartment until use.

In particular, when the base product, such. B. Si ^¬ rup, which has a tendency for sticking, the mixing chamber and possibly passages, openings or connecting channels is kept away from the base product, which otherwise could affect the functioning of, for example, the adjusting element.

The formation of only two chambers within the container simplifies the design and manufacture of the

Container.

Both chambers are preferably by a common

Top wall and common bottom wall limited.

The only movable component is the adjusting element, which is preferably piston-shaped or tubular. The adjusting element is preferably arranged slidingly and / or sealingly guided in the second chamber.

The passage of the adjusting element has an inlet opening, which is preferably the perforable cover Wall area is arranged opposite one another. In this exporting ^¬ approximately form a linear through-channel is provided, preferably extending in the vertical direction by the adjusting element.

Inlet and outlet openings are arranged on the adjustment gege ^¬ nüberliegend. The liquid which flows through this passage channel forms the main flow, which is supplied to the base ^¬ product as a side flow, which preferably takes place laterally.

Under perforable is understood that the wall portion in question can be opened in any way. The opening of the wall region can be done for example by cutting or slicing, piercing, piercing or tearing.

The adjustment element is preferably movable from the rest position into the push-through position by means of a connection and delivery means, which may be a combined connection and delivery means. Such connection and dispensing means are components of a device in which the container is used. Such a device may be a beverage machine, wherein the connection and dispensing means z. B. may be a connection piece. By means of such connection and delivery means, which has preferably at least a corresponding cutting and / or piercing means, the top wall of the Behäl ^¬ ters is opened.

The liquid is fed by means of the connection and delivery ^¬ means of the mixing chamber of the adjusting element. Here, the liquid is preferably first introduced into the Durchgangska ^¬ nal of the adjustment, from where the

Liquid enters the mixing chamber. The liquid is preferably z. B. promoted by means of a liquid pump to on ^¬ closing and dispensing means. This liquid pump is preferably designed for a high flow rate and low pressure. In this case, the liquid is fed almost without pressure to the connecting and discharging means.

The design of the adjusting element with passage ^¬ channel and mixing chamber has the further advantage that the externally on the machine side connection and dispensing means to guided liquid - up to the hydrostatic pressure - even without pressure, that can be supplied without additional pressure. Within the container, in particular within the Verstellele ^¬ Mentes are no obstacles that could possibly lead to a backwater, so that the liquid unge ^¬ prevented by the container can flow. Preferably, the diameter of the passage channel of the adjusting RESIZE ^¬ SSER / equal to the diameter of the channel of the connection and

Means of delivery. The externally supplied liquid is introduced into the adjusting element and only mixed in the mixing chamber of the Ver ^¬ setting element to the base product. The finished product is released from the adjustment.

In order to discharge the base product from the first chamber and to supply it to the mixing chamber of the adjusting element, the first chamber has means for supplying a compressed gas. The ^¬ se means may allow an indirect or immediate supply of the compressed gas into the first chamber. As compressed gas which can be introduced into the first chamber, air is preferably used.

The air under atmospheric pressure is understood as pressure ^¬ gas. Depending on the consistency of the base product, it may be sufficient to open in use only the first chamber, z. B., thus air into the first chamber

can flow in and the base product from the first chamber z. B. can drain.

There is preferably a gas at a pressure greater initiate the AT ^¬ mosphärendruck in the first chamber. For this purpose, the associated device preferably has a compressed gas pump.

By pushing out the base product from the ERS th chamber by means of a pressurized gas, the mixing chamber of the adjusting element supplied amount of the base product, regardless of the flow rate of fluid controlled DER ^¬ the. It is thereby possible to control the amount of the base product supplied to the mixing chamber and thus to adjust the concentration of the base product in the finished product in a targeted manner.

The discharge of the base product from the first chamber is independent of the pressure and velocity of the liquid. The passage of the liquid through the adjustment and the discharge of the base product are decoupled.

Preferably, at least one chamber wall is arranged between the first chamber and the second chamber, in which at least one connection opening is provided. Through the connection opening, the base product is discharged into the second chamber, where the movable adjusting element is located with the mixing chamber. According to one embodiment can be adjusted by the size of the cross section of the connection opening and / or the number of connection openings, the discharged amount per unit time ^¬ unit of the base product. Depending on the nature of the base product and / or the pressure of the compressed gas, an adjustment of the amount per unit of time can thus additionally be made via the connection opening.

Preferably, the connection opening is adjacent to

Bottom wall of the first chamber arranged. This has the advantage that as far as possible no residues of the base product remain in the first ^chamber and the base product is completely discharged. The bottom wall of the first chamber is preferably identical to the bottom wall of the disposable container.

The adjustment can close the connection opening in its rest position and release the connection opening in its push-through position. This has the advantage that until the use of the container, the base product is trapped in the first chamber and can not inadvertently get into the second Kam ^¬ mer. Only then, if the container z. B. is used and used in a beverage machine and the adjustment ^¬ element is moved to its push-through position, what

For example, by a machine-side connection piece, the connection opening is released. The base product is discharged from the first chamber and the

Mixed mixing chamber of the adjusting element supplied, wherein it ^{respects ¬} Lich the design of the mixing chamber different

There are embodiments.

According to a first embodiment, a portion of the passageway forms the mixing chamber. In this case, the base product is fed to a location of the passageway where then the mixing takes place. For this purpose, preferably, the adjusting element on at least one connecting channel, which opens into the mixing chamber, wherein the inlet opening of the connecting channel in the push-through position of the adjusting element of

Opposite opening.

According to a further embodiment, the connecting channel comprises an annular groove or an annular channel in the

Outside surface of the adjusting element. Such an annular groove is preferably used to distribute the base product around the through-channel and from there over two or more

Supply connecting channels to the through-channel. Also in the ^¬ ser embodiment, a portion of the through passage forms the mixing chamber.

Instead of the size of the cross-section of the connection opening and / or the number of connection openings on their cross-sectional sizes, the amount discharged per unit time of the base product from the first chamber according to a further embodiment on the size of the cross section of the connection channel and / or the number of connection channels be set on the cross-sectional sizes. This execution ^¬ form has the advantage that containers with uniform

Connection openings can be used and the dosage can be realized via adjusting elements with different connection channels.

According to a further embodiment, the mixing chamber may be arranged adjacent to the through-channel. The

Mixing chamber may be directly adjacent to the passageway or connected via passageways with this. In this embodiment, the mixing takes place substantially in this mixing chamber, wherein a portion of the passage Kals ^¬ nals can also participate in the mixing.

In this embodiment, the liquid may flow from the passageway into the mixing chamber where it mixes with the supplied base product. To the inflow of the liquid from the passageway into the mixing chamber to be made ^¬ union is to be dimensioned according to the mixing chamber. The mixing chamber may preferably be designed such that it at least partially surrounds the passageway. Especially be ^¬ vorzugt the mixing chamber is an annular chamber.

Preferably, the mixing chamber is in the push-through position of the adjustment of the connection opening in the chamber wall opposite.

In order to allow the liquid to flow into this adjacent mixing chamber, this is preferably connected via windows to the through-channel. The size of the window is to be chosen depending on the fluid and the base product so that the inflow of the fluid is ensured in the mixing chamber.

The first chamber preferably has means for ^¬ A circuit of a pressurized gas into the first chamber.

Preferably, the means for the introduction of a compressed gas comprise at least one perforable cover wall area in the region of the first chamber. This perforable cover wall region can be pierced, for example, by means of a needle or the like, so that air can flow into the first chamber, or be pierced by a connection and delivery means of a beverage machine, so that a feed opening is formed. The compressed gas can be supplied directly to the first chamber in this embodiment.

According to another embodiment, the means for the introduction of a compressed gas comprise at least one inlet opening in the chamber wall. According to this embodiment, the top wall remains closed in the region of the first chamber. The compressed gas may, for example, a machine-side connection and delivery means by which the liquid supplied to the container ^¬ leads are introduced. In this embodiment, the compressed gas is introduced into the second chamber and from there via the inlet ^¬ opening in the chamber wall in the first chamber. This embodiment has the advantage that a machine-side Druckan ^¬ closing element can not come into contact with the base product in the supply of the compressed gas and thus high hygiene requirements can be met. Both the connection opening and the inlet opening in the chamber wall may also be formed as channels when z. B. the chamber wall should be thick-walled.

Preferably, the inlet opening is arranged adjacent to the top wall. Since a complete filling of the first chamber with the base product for bottling technical reasons usually should not be done, remains between the base product and the top wall a free space. The compressed gas can thus be introduced into the ^¬ sen free space.

Preferably, the adjusting element closes in his

Rest position the inlet opening and releases the inlet opening in its push-through position. This has the advantage that until the use of the container, the base product is trapped in the first chamber and can not inadvertently get into the second chamber. Only when the disposable container is used and the adjusting element is moved into its push-through position, which takes place, for example, by a machine-side connecting piece, the inlet opening for the introduction of Druckga ^¬ ses is opened in the first chamber.

Preferably, the adjusting element has at least one

Compressed gas passage on. In this embodiment, the compressed gas is first introduced into the adjusting element and introduced from there through the compressed gas passage and the inlet opening in the chamber wall in the first chamber. Particularly at high pressure of the compressed gas, a better sealing can be achieved between the adjusting element and compressed gas connection.

Preferably, the compressed gas passage is in piercing ^¬ position of the adjusting element of the inlet opening in the

Chamber wall opposite.

The first chamber is preferably only partially with the

Filled basic product. This leaves between the base product and the top wall a space in which the compressed gas can be introduced.

Preferably, the first chamber is filled to below the inlet opening through which the compressed gas is introduced, with the base product. Preferably, the top wall at least in the perfo ^¬ regener- top wall area on a slide. This is preferably a sealing film which tightly seals the interior of the container so that the base product can not escape. This film can be by means of a cutting and / or shock device, for. B. a machine-side connection, open. In this case, for example, the film is cut open or torn open, whereby a feed opening in the film is created, through which the liquid and / or the compressed gas can be introduced into the interior of the container.

According to a further embodiment, the cover wall may have a cover plate which has at least one predetermined breaking line at least in the perforable cover wall region. Such a cover plate can be used instead of a foil and is also opened by means of a cutting and / or pushing device at the intended location or places where predetermined breaking lines are present. This is a slide from the

Broken out cover plate, said plate preferably remains connected via a hinge-like portion after opening with the cover plate. Falling into the interior of the container is thereby avoided. The interior is not contaminated by the platelets. A versehentli ^¬ ches blocking flow openings in the chamber wall by falling plate can be effectively prevented.

Advantageously, the bottom wall also has a film at least in the perforable area. This film is preferably arranged in the region of the second chamber, in which the adjusting element is arranged to be movable. The adjusting element is preferably by a machine side

Socket pressed down and opens this slide with ^{¬ means of} his cutting and / or bumper. In this way, the outlet opening is formed in the bottom wall.

The cutting and / or pushing device of the adjusting element is preferably designed such that no

Cut out or tear film parts, which in the below the container, z. In a beverage machine, provided collecting container, such. B. a beaker or the like may fall. Such cutting and / or

Push device can also have the connection and dispensing means on ^¬ .

Also, the bottom wall, like the top wall having a bottom ^¬ plate, at least in the perforable

Bottom wall region has at least one predetermined breaking line. Also in this embodiment can be advantageously provided as well as a cover plate, that the broken-out platelets remains connected to the bottom wall.

Preferably, the adjusting element on the cover ^¬ wall adjacent end connecting means which can cooperate with a machine-side connecting piece. The connecting piece engages the connecting means of the adjusting element and moves it from its rest position into the

Piercing position. Here, a liquid is introduced into the passage of the Verstellelemen ^¬ tes means of the connecting ^piece . Also a compressed gas can over this

Connecting piece to be supplied.

Preferably, the connection means of the Verstellele ^¬ ments an insertion support and the insertion support

arranged sealing seat. This sealing seat can be designed as annular bead. The sealing seat is required so that the fluid can flow without losses in the passageway. Preferably, the cross section of the channel of the connecting piece is equal to the cross section of the through channel in the adjusting element.

Under a base product, a powdered and / or liquid product is meant, which may consist of one or several ^¬ ren components. The basic product can

for example, a syrup, a concentrate or an extract. The base product is miscible with the externally supplied liquid and is preferably soluble in this liquid.

The base product is a food, a Nahrungser ^¬ gänzungsmittel, a health food, a

pharmaceutical product or a cleaning agent.

Depending on the nature of the basic product, the type of liquid ^¬ ness is to be selected. The associated device in which the Container can be used, is aligned to the intended use and equipped.

Preferably, this device is a beverage machine, in the container, in particular disposable containers, can be used, with the content z. B. drinking water can be changed taste.

In Figures 1 and 2, a container 10 is shown in two perspective views, preferably as

Disposable container is used. The container 10 has a top wall 40, a peripheral wall 30 and a bottom wall 50. In the embodiment shown here, the top wall 40 is formed by a film 41 which is mounted on an annular bead 32 of the peripheral wall 30.

The bottom wall 50 is composed of a ring plate 52 and a centrally disposed film 54. Both the top wall 40 and the bottom wall 50 and the film 54 have a perfo ^¬ regener- wall portion 43, 56th

Furthermore, the bottom wall 50 has two annular ribs 60 and radial ribs 62 between the two annular ribs 60.

FIG. 3 shows a vertical section through the container 10 shown in FIGS. 1 and 2, with only one annular rib 60 and no radial ribs 62

are drawn.

The interior of the container 10 is divided into a first Kam ^¬ mer 12 and a second chamber 18. In the embodiment shown here, the chamber 18 is arranged centrally and is surrounded by the annularly shaped first chamber 12. This is a rotationally symmetric

Arrangement. Other embodiments, such. B. asymmetric arrangements are also possible. Both chambers are separated by a chamber wall 20. The circumferential wall 30, the Ringplat ^¬ te 52, the annular rib 60 and the chamber wall 20 are integrally formed, for example by injection molding.

In the first chamber 12 is a base product 14, which may consist of a consumable liquid. Above the level of the base product, a free space ^¬ 16, in the air or an inert gas is located. In the second chamber 18 is an adjustment 100, which is in the figure 3 in the rest position.

Above the container 10, a connecting piece 200 is likewise shown in section, which can be moved in the direction of the arrow along the axis 104 from top to bottom and can penetrate into the second chamber 18. By means of this Anschlussstut ^¬ zen 200, the adjusting element 100 moves downwards, so that this is the bottom wall may pierce the foil 50 54th The axle 104 also forms the longitudinal axes of the connecting piece 200 and that of the adjusting element 100.

The container 10 has a cover wall 40, which consists of a film 41. This film 41 is fastened sealingly on the annular collar 32 of the peripheral wall 30 and the annular collar 22 of the chamber wall 20, so that the chamber 12, 18 and thus also the

Container contents, ie the base product 14, airtight ^{abgeschlos ¬} sen are. The cover wall 40 has at least in the region of the second chamber 18 the perforable cover wall region 43.

The bottom wall 50 includes the annular plate 52 with an annular rib 60, the film 54 is buildin ^¬ Untitled at its end face, which also has a perforable wall portion 56 in the region of the second chamber eighteenth The adjusting element 100 located in the second chamber 18 has a base body 102 which is formed in a piston-shaped or tubular manner and which is subdivided into an upper section 192 and a lower section 194. The outer surface 103 of the adjusting element 100 bears sealingly against the chamber wall 20. The adjustment Ment 100, which is in its rest position lies with the end face of its upper portion 192 on the annular collar 22 of the chamber wall 20 at.

In the center of the adjusting element 100, a through-channel 170 is arranged, which has an inlet opening 171 and an outlet opening 179. The passage 170 be ^¬ sits below the inlet opening 171 a

Connecting portion 178 of a first diameter-sized ^¬ ren section 178 a and a second larger diameter

Section 178b is formed. In this connection portion 178 of the connecting piece 200 engages (see Figure 4), wherein the first portion 178 a facilitates the insertion.

This connector portion 178 is via an ^¬ transition section 177, which forms a sealing seat 198, into the upper portion 172 of the through passage 170 which has in comparison ^¬ equal to the terminal portion 178 has a smaller diameter. This is followed by a portion of the Mischkam ^¬ mer forms 176, as well as the lower portion 174 connects. The

Sections 172, 174 and 176 have the same diameter.

In the horizontal direction two Verbindungsungskanä ^¬ le 180 are formed with inlet 182 and outlet opening 184 in the distribution element 100, which extend from the outer surface 103 into the mixing chamber 176 in the passage 170. About these connection channels 180, the base product is the

Through passage 170 and thus the mixing chamber 176 supplied.

This will be explained in more detail in connection with FIG. The connection channels 180 are located between the upper portion 192 and the lower portion 194 of the adjustment 100.

At the lower end of the adjusting element 100 in the region of the outlet opening 179, a cutting and / or pusher 110 is provided, which is formed in the embodiment shown here as a tip.

In the chamber wall 20 adjacent to the bottom wall 50 connecting openings 24 are provided which connect the first with the second chamber. 3, these connecting openings 24 are closed by the lower section 194 of the adjusting element 100. sen. As can be seen in the figure 4, this connection ^¬ openings 24 are opened in the piercing position of the adjusting element 100, so that this connection openings 24 are aligned with the respective opposite entry openings 182 of the connection channels 180, and the left in the first chamber 12 base ^¬ Product 14 can drain away.

In the upper region of the chamber wall 20 below the top wall 40 inlet openings 26 are provided through which a

Compressed gas in the above the base product 14 located free space 16 of the first chamber 12 can be initiated. These inlet openings 26 are closed in the rest position of the adjusting element 100 from the upper portion 192 of the adjusting element 100 and released in the puncture position (Figure 4), so that a pressurized fluid can be introduced.

The connecting piece 200 has a flange part 202 which has an upper side 204 and a lower side 206. At the clip ^¬ circuit 200 further has a flange portion 202 at the

second pipe section 208, at the lower end also a cutting and / or pusher 210 is arranged in the form of a conical tip. The connecting piece 200 has a first passage 212, through which a liquid z. B. can be passed from a storage tank, not shown. In addition to the first passage 212, a second passage ^¬ channel 214 is provided in the flange part, through which a compressed gas can be supplied. For sealing, sealing elements 220 are provided in the lower region of the flange part 202.

In the figure 4, the puncture position of the adjusting element 100 is shown. If the machine side

Connecting piece 200 is moved downward in the arrow direction, the cutting and / or pusher 210 pierces the deck ^¬ wall 40 in the region of the perforable portion 43 of the film 41, whereby a feed opening 46 is formed. The tube part 208 engages in the connection section 178 of the adjusting element 100 and rests against the sealing seat 198. The two passageways 212 and 170 have the same diameter and are aligned with each other. When piercing the top wall 40, the film 41 breaks and the film ends 41 a, b protrude into the second chamber 18.

The adjustment element 100 cuts through the film 54, whereby the outlet opening 59 and the film ends 54 a, b are formed, which also hang down on the attached part of the film 54. In both cases, no tearing of pieces of film takes place, which could possibly contaminate the interior of the Behäl ^{¬ age} 10 or can fall into a placed under the container 10 collecting vessel.

The two connection channels 180 are located on the

Height of the connecting openings 24, so that the base product 14 from the first chamber 12 can penetrate into the connecting channels 180 and from there into the mixing chamber 176 can pass. In the

Mixing chamber 176 takes place mixing of the base product 14 with the over the passageway 212 and the upper portion 172 of the passageway 170 liquid supplied instead.

This liquid fed from above forms the main stream to which the base product is fed as a by-pass stream. The Mischkam ^¬ mer 176 defines the area where both streams are combined. Both components then flow into the lower portion 174 of the through-channel, where a further Durchmi ^¬ tion of both components can take place.

To herauszu ^¬ press the base product from the first chamber 12, the through the second passageway 214

Connecting piece 200 a compressed gas, such as air, introduced into the second chamber 18. The sealing elements 220 sit on top of the top wall 40. The pressurized gas passes from the second chamber 18 through the inlet opening 26 into the free space 16 and pushes the base product 14 downwards (see arrows) and through the connection openings 24. Via a control of the

Compressed gas, the amount that is discharged through the connection openings 24 in the connection channels 180, controlled, so that the concentration of the base product can be adjusted in the liquid.

In Figures 5 and 6, another embodiment is shown, in which the bottom wall 50 is provided additionally with ringförmi ^¬ gen ribs 60th Furthermore, the chamber wall has a Shoulder 28, so that the second chamber 18 has an upper durchmes ^¬ smaller section 29a and a lower diameter larger portion 29b. The adjustment element 100 located in the second chamber is adapted to this configuration of the chamber wall 20 with respect to the outside diameter. The adjusting element 100 thus has a shoulder 28 complementary shoulder 109, which serves as a stop when inserting the adjusting element 100 in the second chamber 12.

In contrast to the embodiment shown in Figures 3 and 4, the adjusting element 100 has in ^{Anschlußab ¬ section} 178, compressed gas passages 160 and an external

Ring groove 162 or annular channel. In the rest position shown in Figure 5, the pressure fluid passages 160 are above the inlet opening 26, which are closed by the insertion port 196 of the Ver adjusting element 100. The connecting piece 200 has - as in the embodiment of Figures 3 and 4 - except the first passage 212, a second passage 214 for the pressurized fluid having at the lower end an annular groove 215 or annular channel through which the pressurized fluid is discharged in the horizontal direction , If, as shown in Figure 6, the connecting piece 200 acts on the adjusting element 100, the annular groove 215 is opposite the Druckfluiddurchlässen 160 and this, or the annular groove 162, in turn, the inlet openings 26 are opposite, so that the pressurized fluid in the first chamber 12 can be initiated.

The adjustment element 100 has an annular channel, in particular ^¬ sondere an annular groove 186, which is connected via two connecting channels 180 to the passageway 170 in communication. It is also possible to provide only one connection channel 180 or more than two connection channels 180. The cross section of the connecting channel 180 or the sum of the cross sections of the connecting channels 180 is smaller than the sum of the cross sections of the Verbindungsöff ^¬ openings 24, so that the metering of the passage 170 and thus the mixing chamber 176 supplied base product 14 via the connecting channels 180 takes place. The annular groove 186 has the advantage that the adjusting element 100 when inserted into the second chamber 12 with respect to the connection openings 24 does not have to be aligned.

The puncture position of the adjusting element 100 can be seen in FIG.

In the Figure 7, another embodiment is shown which differs from the previously described embodiments in that the top wall 40 is not made of a Fo ^¬ lie but of a cover plate 42nd Also, the film located in the bottom wall 50 has been replaced by a corresponding bottom plate 55.

This cover plate 42 has two perforable deck ^¬ wall portions 43 and 47, which are limited by predetermined breaking lines 44. Likewise, the bottom plate 55 has a perforable area 56 with predetermined breaking lines 58.

The connecting piece 200 is modified insofar as that the second passage 214 for the supply of the pressure ^¬ gases laterally of the tubular member 208 in a tubular member 209 with

Cutting and / or pusher 21 is längordnet. When the connection piece 200 is lowered, as shown in FIG. 6, the pipe part 208 engages in the connection section

178 of the adjusting element 100, wherein the perforable cover ^¬ area 43 is pierced. It is thereby broken out a plate 45, which hangs due to its hinge-like connection to the cover plate 42.

The tube part 209 with the cutting and / or Stoßeinrich ^¬ device 211 pierces the perforable top wall portion 47 in the region of the first chamber 12 and breaks in the same way a plate 45 out of the top wall plate 42, which also hangs on the cover plate 42. The compressed gas is introduced through the supply opening 48 created in this way via the second

Through passage 214 is supplied directly to the chamber 12. As a result of the movement of the adjusting element 100 downwards, the bottom wall in the region of the perforable bottom wall region 56 is also pierced, so that here too a small plate 57 is released, which remains hanging on the bottom plate 56.

In Figures 9 and 10, another form of the adjustment execution ^¬ 100 is shown, in which the Mixing chamber 176 is disposed adjacent to the passageway 170. In FIG. 9 it can be seen that the upper and lower sections 192, 194 of the adjusting element 100 are each formed by an upper and a lower cylinder, wherein the cutting and / or pushing device 110 is arranged on the lower side of the lower cylinder 194. Both cylinders are connected to each other via three webs 190, between which windows 188 are formed. The windows 188 have cross sections which are considerably larger than the cross sections of the connecting opening 24, so that the inflowing liquid can penetrate from above in this Be ^¬ rich and thus fills the mixing chamber 176th The Ba ^¬ sisprodukt 14 supplied via the connection opening 24 of the chamber wall 20 thus passes directly into this mixing chamber 176 and is then discharged down through the lower portion of the passage channel 170. Depending on the consistency of the base ^¬ product mixing with the liquid can also

Continuity channel 170 continued.

Within the upper cylinder 192 is in Anschlussab ^{¬ section} 178 as connecting means an insertion port 196 is arranged with an inwardly facing annular bead 197 which forms the sealing seat 198 for the connection piece (not shown).

The upper portion 192 of the adjustment 100 be ^¬ sits at the upper end and at the lower end of the outer surface 103 adjacent to the mixing chamber 176 each have a sealing bead 120, 122. Also, the lower portion 194 has on the outer surface 103 also adjacent to the mixing chamber 176 and at the bottom End je ^¬ Weils a sealing bead 124, 126 on.

FIG. 11 schematically shows a beverage machine 300, into which a container 10, which is shown in exaggerated fashion, is inserted into a receiving device 340. The beverage machine 300 has a housing 310 and is divided into a first housing part 320 and a second, laterally arranged housing part 330. Above the container 10 there is a connection and delivery means 200a in the form of a connecting piece 200, which is movable within the

Beverage machine 300 is arranged. Below the container 10 is a vessel 345th FIG. 11 shows a container 10 and a connecting piece 200, as have been described in connection with FIGS. 5 and 6. The connecting piece 200 is connected to a storage tank 350 in the second housing part 330, in which, for example, water 354 is located. This water is supplied by means of a liquid pump 355 via a connection ^¬ line 352 and optionally via a filter device 356 the connecting piece 200.

In addition, a compressed gas line 360 is provided which has a compressed gas pump 362 which sucks air from the outside. The connecting line 352 is connected to the passage 212 of the connecting piece 200 and the compressed gas channel to the passage 214 of the connecting piece.

The connecting piece 200 is guided in a tubular guide element 322 and moved by means of a not ^{dargestell ¬} th actuator in the vertical direction. The leads 352 and 360 have flexible portions 353 and 361.

If, as shown in Figure 12, the terminal ^¬ clip has been inserted into the container 10 200 air is supplied through the pressure gas line and the base product 14 pushed out of the first chamber 12 so that this in the

Mixing chamber 176 passes. The finished product is discharged downwards and collected by the vessel 345.
