Description

The present invention relates to a device for removing liquids from deformable containers, for example plastic containers, and to the deformable container itself. The present invention will be described with reference to a so-called dispensing unit, which can be used in particular in bar areas. However, such dispensers can also find application in private use. In addition to plastic containers and containers made of other materials (for example, aluminum) can be used, but in particular such containers, the material can be, without tearing, reshape. In the following, however, the term plastic container is also used as a representative for other containers.

It should also be noted that the present invention is particularly suitable for low viscosity liquids such as waters, beers, soft drinks and the like. However, however, the invention could be applied to higher viscosity media such as oils, ketchup, soaps, or the like.

Various devices for removing liquids from containers are known from the prior art.

For example, describes the DE 10 2007 054 431 A1 a device for removing liquids from a container. In this case, a deformation element is used, which deforms the container, said deformation element here folds the container to be emptied and in this way an almost complete removal of the liquid allows the container. The disclosure of the DE 10 2007 054 431 A1 is hereby fully made the disclosure content of the present invention.

The present invention has for its object to improve such dispensers for liquids and drinks in particular with regard to their handling.

Furthermore, it should be ensured that the container introduced into the dispensing system is a container approved for the dispensing system. It should also be avoided that with the dispensing container containers are processed with wrong or unwanted content. This is achieved according to the invention by the subject matters of the independent claims.

Advantageous embodiments and further developments are the subject of the dependent claims.

A device according to the invention for removing liquids from deformable containers has a first holding device, which is suitable for holding a first portion of the container, and a second holding device, which is suitable for holding a second portion of the container, wherein the second portion of the container spaced is arranged from the first portion of the container and wherein the holding means are arranged such that the container is at least partially arrangeable between these holding means and so by a relative movement of a holding device relative to the other holding means is deformable and with a drive means for generating a relative movement between the first Holding means and the second holding means, so as to deform the container arranged between these holding means such that its inner volume is reduced, and with a removal eeinrichtung, which has a flow connection to the interior of the container and via which liquid contained in the container can be removed as a result of compression of the container.

For example, should the signal be relatively weak, the readout device or controller may recognize this and conclude that this error has possibly been caused due to a wrong position and / or orientation of the container within the device (m). Thus, the controller may issue this error and the operator is instructed to check the container for its orientation and / or position (g, h). This error could also have to be acknowledged after verification. For other error messages, such as an exceeded best before date (s), an acknowledgment function could be excluded.

The read-out device is preferably mounted in the vicinity of the container. In this way it is possible to read the information from the container better - especially if it is attached to this only a passive RFID chip. When reading out of the container mounted active RFID chips, the distance of the read-out device is not so crucial - in this case, it is advantageous to accommodate them on a wall or a frame of the device, in the vicinity of which there are no moving parts. In particular, in the vicinity of the control device would also be a good place.

The read-out device is preferably arranged in the vicinity of a holding device, in particular within a distance of less than two meters, preferably below one meter. The distance can be less than 20cm.

In particular, the readout device can also be arranged directly on a holding device.

The first holding device and the second holding device are in particular arranged such that the container can be arranged upright and with the mouth pointing upwards between them. Above is related to the distance from the center of the earth. However, it would also be conceivable to arrange the container upside down or in a horizontal orientation in the device.

The read-out device can be arranged, for example, on the first holding device. In this position, with her on a bottom portion of the container attached, in particular passive, RFID chip read well.

The read-out device can also be arranged on the second holding device. In this position, it is easy to read out a, in particular passive, RFID chip attached to an opening region of the container.

The read-out device can be moved with one of the recordings.

It is also possible to arrange a plurality of readout devices in the vicinity of or on one or both holding devices. In this way, for example, different containers can be processed with different position of the identification element.

The read-out device can also be arranged stationarily in the vicinity of a holding device.

The control device or device can in particular also the relative movement of a holding device relative to the other holding device or the removal the liquid via the removal device in (at least indirectly) depending on an internal pressure within the container controls. By the method, in particular, the subject of the above application DE 10 2007 054431 The manner and direction in which the container is deformed is broadened and, in particular, the manner in which the emptying of the container is controlled. By "at least indirect dependence" is meant that a control in immediate dependence on the internal pressure is possible, but also in indirect dependence (for example, depending on a drive torque of the drive device, which depends on the internal pressure in the container or in dependence on the pressure the liquid in the withdrawal device).

The drive device may in particular be an electric motor, which controls the relative movement of the holding devices relative to one another via a spindle drive, for example. Advantageously, therefore, the drive device also has a transmission device which converts a drive speed of the drive motor into a lower movement speed.

In addition, however, the use of hydraulic or pneumatic drives for moving the holding devices relative to each other would be conceivable. Advantageously, the movement of the holding device relative to each other is rectilinear and in particular along a longitudinal direction of the container. It would be possible that a holding device is arranged stationary and moves the other of these opposite. However, it would also be possible for both holding devices to be moved.

In a further advantageous embodiment, a carrier is provided on which at least one holding device is arranged. Advantageously, the other holding device is arranged on a corresponding carrier.

In a further advantageous embodiment, a holding device extends in the longitudinal direction of the container and preferably has a length which corresponds to at least one third of the total length of the container. This embodiment has the advantage of being particularly compact.

In a further advantageous embodiment, the first holding device serves to hold a bottom region of the container. For this purpose, for example, the first holding device have a recess into which a bottom portion of the container can be introduced. It would be possible that the holding device is adapted to a shape of the bottom of the container. However, it would also be possible that this holding device, for example, hemispherical or formed in a similar manner. Advantageously, the device according to the invention is designed such that it is suitable for liquid removal from commercially available containers. In particular, the device is also designed such that it is suitable for removing liquids from containers which have standard closures, such as plastic screw closures.

In a further advantageous embodiment, the second holding device serves to hold a mouth region of the container. It would be possible that an inner surface of the first holding device is adapted in terms of their geometric shape to an outer surface of the container. In this case, the container can be compressed so strong with correspondingly strong drives that almost the entire liquid can be removed from the container. Unlike the one in the DE 10 2007 054431 A1 shown device in which a special container is used, this is also possible in such containers, which have differently shaped bottoms, such as in PET bottles usual floors, such as petaloid floors. Advantageously, the second holding device has a recess for receiving a closure of the container.

The control device causes in particular that, for example, a compression of the container is stopped at a certain maximum pressure. In this way, on the one hand the risk of bursting of the container can be prevented and on the other hand, it can also be prevented that liquid is removed with too high pressure. For these control devices described below in detail different ways are conceivable. The maximum pressure could be read out by the read-out device and forwarded to the control device. It may also be a manually adjustable or fixed maximum pressure value.

As mentioned above, the device for removing the liquid can be carried out with relatively simple means. For example, the PET container by means of threaded spindles and an electric drive can be pressed together so that the container can be reduced to a very small volume in order to empty the container to a very small residual volume. Advantageously, the container is a container having a size between 2 and 10 liters and in a commercial application between 10 and 30 liters.

In a further advantageous embodiment, the first holding device and the second holding device are arranged such that the container can be arranged standing and with its mouth facing upwards between them. In this way, it can be prevented that, for example, fluid leaks unintentionally if the removal system becomes defective.

In a further advantageous embodiment, the first holding device has a stamp element which has a smaller cross-section than a base body of the container. In this way, the container can be folded so that its inner volume is minimized as possible. This was in the above mentioned DE 10 2007 054431 A1 explained. The readout unit can also be fastened or arranged in or on the stamp.

In a further advantageous embodiment, in an initial state, a distance between the first holding device and the second holding device can be changed so as to be able to adapt to different containers. It would also be possible for the holding devices to be interchangeable or for adapter elements to be provided which allow adaptation to different containers.

Advantageously, at least one section between the two holding devices is formed without a housing. This means that at least a portion of the container to be compressed during the compression process is not surrounded by an immediately adjacent housing. Such an immediately surrounding housing would disturb the movements of the holding devices. While in the prior art housings are provided in many removal devices, which support the containers during their emptying, the Applicant has found that such housing, to which the container is directly applied, are not absolutely necessary.

In a further advantageous embodiment, the control device has a switching device, which in response to an internal pressure within the container the drive device on or off. This may be, for example, a mechanical switch. So it is possible that the container pressure is readjusted when taking the liquid. Thus, it would be possible, for example, that the pressing force is applied via compression springs and / or readjusted via a two-point control. This will be explained in more detail with reference to the figures. It would also be possible that for a residual emptying of the pressure is largely or even completely drained.

The switching device may be a mechanical switching element. However, it would also be an electronic switch conceivable that reacts, for example, to a measured pressure. Advantageously, at least one holding device is resiliently mounted and particularly preferably connected to the switching device.

In a further advantageous embodiment, the removal device has at least one flexible conduit section. Advantageously, a flow rate change element is arranged on this flexible line section, for example a compression element which can reduce the line cross section.

In a further advantageous embodiment, a pressure sensor element is provided which detects an internal pressure in the container and the control device controls the drive device as a function of values which are output by this pressure sensor element. In addition, the control can also take place via a temperature sensor element.

In a further advantageous embodiment, it would also be possible for the pressure to be determined indirectly via a drive torque of the drive device and for the drive device to be switched off when a specific limit drive torque is exceeded.

In a further advantageous embodiment, the device has an actuatable valve for removing the liquid. Thus, for example, the device may have an outlet which, for example, is manually operable so as to remove the liquid from the container. As a result of such a removal, the internal pressure in the container will change and the drive device can continue in particular with the compression of the container.

In a further advantageous embodiment is increased by a punch movement or a relative movement of the two holding devices to each other to the pressure of the container and by this pressure increase, the decrease amount can be specified. In a further advantageous embodiment, a pressure regulating valve can also be provided for this purpose. This pressure control valve can advantageously be a combination of a shut-off valve, a pressure regulator and a diffuser. In a further embodiment, the dispensing of the liquid is advantageously controlled by switching the drive device on and off. By switching on the drive device, the internal pressure in the container and thus also the pressure of the liquid in the extraction device increases. Due to this increasing pressure, a bleed valve can open and liquid can be removed. This removal valve can be regulated so that a bursting of the container due to overpressure is prevented in any case.

The above-mentioned flexible conduit means can be tightly squeezed off to shut off and be opened to remove the liquid, in particular only be opened so far that is reduced by a small opening of the container pressure to a desired flow rate. Furthermore, it is also possible for a tube cross section to expand starting from a throttle cross section in the length and shape of a diffuser.

In a further advantageous embodiment, the flexible conduit element or the hose is advantageously squeezed to the outlet during the closing operation so as to be able to express residual fluid. This serves, for example, as Auspresshilfe.

In a further advantageous embodiment, the device has a movement element, which moves the container relative to a holding device. In this movement element is in particular a moving element, which the container relative to a holding device, in particular a holding device which penetrates into the container (in the following FIG. 1 this is the upper holding device) moves when moving apart of the two holding devices. In this way, at least partial stripping of the container can be achieved, so that the container can be more easily removed from the holding device. The fact that a holding device has a smaller cross section than the base body of the container, penetrates then this when emptying the container in this one. In order not to have to remove the container completely manually from this holding device, it is therefore proposed that by means of the movement element or stripping element in particular a backward movement of the holding device or a movement apart of the two holding devices is used to strip the container of the holding device.

In a further advantageous embodiment, the holding device is designed such that it can receive an opening region of the container. For this purpose, the holding device itself may have a recess, which is designed to receive the mouth region of the container.

In a further advantageous embodiment, the removal device has a piercing device for piercing at least one wall of the container or a container closure of the container. In particular, a piercing device is provided for piercing the container closure. In this way, the removal of liquids from standard containers can be made possible. Thus, for example, this lancing device may be formed as a tubular body with a cutting edge. In this embodiment, on the one hand, a removal of liquid from the container can be achieved, on the other hand, however, preferably also during the removal of a reliable seal the piercing device or the removal device relative to the container. The read-out device can also be arranged on the lancing device.

In a further advantageous embodiment, the removal device is integrated in one of the two holding devices. In particular, the removal device is integrated in that holding device which is provided for receiving the mouth region of the container. In this case, the removal device may be arranged on or particularly preferably within this holding device. Thus, a preferably central cavity can be formed in the holding device, in which the said piercing device and in particular also a pipeline is arranged.

In a further preferred embodiment, that holding device which serves to hold the mouth region of the container, a stamp member having a smaller cross-section than a main body of the container. In this way, the mouth portion of the container when compressing the container in those Section of the container, which adjoins the container bottom, are inserted. In this way, in a compressed state of the container, the mouth region lies in the interior of a volume formed by a circumferential wall of the container.

The present invention further relates to a system with at least two devices of the type described above and a mixing device in which the liquids from the two removal devices of the two devices are miscible. In this way - especially in a post-mix - operation - different liquid components are mixed together.

Thus, it would be possible for the two removal devices to open into a mixing chamber in order to be mixed together to form a liquid mixture. The respective mixing ratios can be regulated via the controls of the two devices. It would also be possible for the two removal devices to open only into a common collecting line, which then represents the said mixing device. Furthermore, it would also be possible for the liquids from the two removal devices to be metered offset in time into a common collecting line or a mixing space.

In a further advantageous embodiment, the device has at least one read-out device for, in particular, wireless read-out of at least one identification element attached to the container. In particular, this may be a device for reading out an RFID element arranged on the container. In this way, the container to be emptied can be identified beyond doubt. In a further advantageous embodiment, the device has a control device, which also controls a removal process as a function of a read-out result of the read-out device. Thus, for example, the user can be informed by means of an alarm that he uses an unsuitable for the removal process container. Also, in response to such readout result, a picking operation may be aborted or its start prevented.

It is also conceivable that the control device, if it determines that no marking element is provided on the container, aborts a withdrawal operation or does not initiate.

It is also possible to realize a method for removing liquids from a container, wherein a container is provided with a first section (of the container) on a first holding device and with a second section (of the container), which is spaced from the first section, is arranged on a second holding device, that the container is at least partially between this first holding device and the second holding device. Furthermore, a holding device is moved to the other holding device in order to deform the container and so as to reduce the inner volume of the container. In this case, liquid is removed from the container by means of a removal device (in particular during compression of the container).

In the method, information which is attached to or in the container is advantageously read out with a read-out unit. In particular, the data obtained is used to control a deformation, dispensing or removal operation. With regard to the readable data and the controllable parameters, reference is made to the above-mentioned embodiments in the description of the device.

The movement of the first holding device relative to the second holding device or the removal of the liquid by means of the removal device is advantageously controlled as a function of an internal pressure of the container.

Advantageously, the container is standing upright and arranged with its mouth up between the holding devices.

In an advantageous method, at least one holding device is substantially stationary. Advantageously, the upper holding device, which holds the mouth region of the container, is substantially stationary and the lower holding device is moved relative to the upper holding device. The removal device is advantageous, stationary in the direction of movement of the holding devices.

However, it would also be possible and preferred that the second holding device is arranged movable relative to the removal device and in particular with respect to a puncture device. In particular, the second holding device is movable in a longitudinal direction of the container, and particularly preferably the second holding device is movable between two predetermined end positions. It is also conceivable that the second holding device is movable, but also in a predetermined position relative to the removal device or the lancing device in the longitudinal direction of the container or the direction of movement of the holding devices can be locked. This can be particularly advantageous for introducing a new, filled container.

In a further advantageous method, a portion of the container, which contains the mouth portion of the container, inserted into a portion of the container containing the bottom portion of the container. In the method described here, it would be possible both to insert the mouth region of the container into the bottom region of the container and, conversely, to insert the bottom region of the container into the mouth region. However, the procedure in which the mouth region is inserted into the bottom region has the advantage that the mouth of the container can be pushed into the bottom region or an adjoining wall region. In this way, the volume of the compressed container can be further lowered.

Thus, preferably that holding device, which carries the bottom portion of the container, a larger cross-section than that holding device which receives the mouth region of the container.

The invention is further directed to a deformable and fillable with a liquid container, having an orifice, a bottom portion and integrally formed with the mouth and the bottom portion body, wherein the base body is bent by a predetermined bending angle to such a predetermined circumferential folding edge of the body in that the mouth of the container is arranged closer to the bottom region than the circumferential folding edge.

According to the invention, at least one identification element (80) is arranged on or in the container (10).

The identification element is in particular an RFID chip, which is designed in particular passively, that does not include its own power source.

The RFID chip can also be rewritable and have a memory on which information about a certain number of past filling operations is stored. For example, it is also possible for defects or incorrectly performed filling processes to be stored.

1. a) ein Identifikationscode des Herstellers und/oder Abfüller des Behältnisses bzw. ein Vorhandensein eines derartigen Codes,
2. b) ein Hersteller- und/oder Abfüllername,
3. c) ein Produktionsdatum und -ort des Behältnisses,
4. d) ein Abfülldatum und -ort des Behälters,
5. e) ein Mindesthaltbarkeitsdatum,
6. f) eine abgefüllte Produktmenge,
7. g) ein Volumen des Behältnisses,
8. h) eine Produktart (Softdrink, Bier, stilles Wasser oder Ähnliches),
9. i) ein Vorhandensein einer Karbonisierung,
10. j) ein Karbonisierungswert des Produkts,
11. k) ein Innendruck des Behältnisses,
12. l) eine aufzubringende Sollkraft für eine Deformierung des Behältnisses,
13. m) eine Position und/oder Ausrichtung des Behältnisses innerhalb der Vorrichtung.

Furthermore, individual or combinations of the following data can be stored on the identification element:

1. a) an identification code of the manufacturer and / or bottler of the container or the presence of such a code;
2. b) a manufacturer and / or filler name,
3. c) a date and place of production of the container,
4. d) a date and place of filling of the container,
5. e) a date of minimum durability,
6. f) a filled product quantity,
7. g) a volume of the container,
8. h) a type of product (soft drink, beer, still water or similar),
9. i) presence of carbonization,
10. j) a carbonation value of the product,
11. k) an internal pressure of the container,
12. l) a desired force to be applied for a deformation of the container,
13. m) a position and / or orientation of the container within the device.

In particular, the mouth region of the container is undeformed. When the container has been manufactured by stretch blow molding, the undeformed mouth region is in particular a support ring, a circlip and / or a threaded region of the container. These areas are normally neither heated nor changed (stretched) in the stretch blow process, so that they maintain their shape obtained by injection molding a preform of the container with a large wall thickness relative to the other areas. "Undeformed" here does not refer to the stretch blow-molding process, but to the removal process of the liquid in the device according to the invention. This means under undeformed in particular understood that apart from a forming process in the original production of the container, so for example, a stretch blow, no further deformation processes in the specified areas so about a mouth area and / or a bottom area are made or occur.

In a further advantageous embodiment of the bottom portion of the container is also undeformed. Preferably, both the mouth region and the bottom region are undeformed.

In particular, a relative position of the folding edge relative to the bottom region of the container during an expansion of the container is variable.

In particular, an outer surface of the base body is at least partially circumferential (and preferably completely encircling) and at least partially opposite to an inner surface of the base body, wherein in this respect between the inner surface and outer surface at least in sections no container wall material. In particular, these are two sections of the container which are separated from one another and by the folding edge. Thus, it is possible that there is a cavity between the inner surface and the outer surface.

The outer surface and the inner surface of the container have in particular at least in sections to each other at a distance which is greater than 0.2 cm.

In particular, two inner surfaces of the main body container can touch in sections.

In particular, a wall thickness of the base body is at least partially substantially constant.

In particular, the identification element is arranged on an undeformed region, in particular on the bottom region or at the mouth region.

However, the identification element can also be arranged on one or in a closure of the container. Likewise, an arrangement of the identification element on, on or in be provided a label which is mounted on the container. In particular, the element can be arranged between the label and the main body.

The identification element can be applied to the container together with or on the label or in a separate step by means of a labeling machine. By a separate step is meant that the element is either attached to the container before the label or after the container has been labeled.

The identification element can also be applied by a printer, in particular by a print head, to the container or to the label. This can be done in the production of the container, in particular after the production of the containers in the stretch blow molding machine and before filling the container. As a result, the identification element may at least partially consist of ink containing conductive ingredients, in particular metal particles. Thus, for example, an antenna of a transponder can be printed, but also other parts of the RFID transponder.

The identification element can also be applied in the in-mold labeling process by a blow molding machine for producing the container. For this purpose, the identification element is preferably placed in an empty blow mold, either together with a label or individually, then a preform is introduced and finally expanded against the blow molding wall and the identification element, so that this example is pressed by the blowing pressure in the container wall. In addition, glue or glue may also be used which is applied to the identification element prior to introduction into the blow mold.

The identification element could also be applied by means of an injection molding machine or a downstream handling device on the preform or introduced by means of Inmoldlabellingverfahren directly into the injection mold.

In a further embodiment, the identification element is inserted into an undercut present in the container and / or inserted, in particular via a handling device. The undercut can be generated during the blowing process or during the injection molding process. By this arrangement of the identification element, a reliable arrangement of the identification element on the container can be achieved.

It would also be conceivable to produce the container by means of extrusion or other blow molding. The attachment of the identification element can then take place analogously to the above statements.

Advantageously, an identification element which can be read in particular without contact is arranged in an area of the container, by means of which at least one piece of information which is characteristic for the container can be read out. This is preferably an RFID element, in particular but not exclusively an RFID chip.

Advantageously, the identification element is inseparably connected to the container. Advantageously, this information is selected from a group of information including a best before date, information about the type of beverage or the like.

For example, it could be ensured that containers whose expiry date has passed are no longer emptied. For example, knowledge of the type of beverage may control relevant parameters for sampling, such as a suitable pressure.

In a preferred embodiment, the identification element is arranged in the form of a label on the container. In addition, it would also be possible for the identification element to be integrated into a region of the container, for example a wall region.

In addition, it is possible that the identification element is already integrated in the manufacture of the containers in this. Thus, it would be conceivable that during a manufacturing process for the container, in particular during a blow molding process, the identification element is already held in a region of a blow molding machine approximately within a wall of a blow mold and is fixed during the forming process of a plastic preform to the container on the wall of the container.

Representations of a container with identification elements.

Fig. 1 shows a representation of a first embodiment of a device according to the invention 1. In this case, the reference numeral 10 refers to a container to be emptied, said container having a bottom portion 10a and an opening portion 10b. The reference numeral 30 denotes a closure of the container, which may be a standard closure here. The reference numeral 10e shows a current folding area at which the container 10 is bent to remove liquid. In a relative movement of a first holding device 2 relative to a second holding device 4, this folding area 10e is also displaced.

The reference numeral 40 indicates in its entirety a removal device to remove liquid from the container. For this purpose, a valve 52 is provided and optionally a throttle body 56, which is preferably upstream of this valve 52. Reference numeral 54 denotes an outlet for the liquid.

The reference numeral 42 denotes a lancing device which can pierce the container closure 30.

The reference numeral 20 designates in its entirety a control device for controlling the removal of the liquid from the container 10 in response to its internal pressure. In this case, a drive device 22, as here an electric motor, is provided, which, as indicated by the arrow P1, the first holding device 2 can move upwards and thus on the here secondarily arranged stationary holding device 4. The first holding device 2 here has a receiving device 24 for receiving the bottom region 10a. Furthermore, springs 28 are provided which press the receiving device and a bottom plate 29 apart.

The reference numeral 32 denotes a switching element which can be switched when the receiving device 24 is moved toward the bottom plate 29. Depending on this switching element, the drive device 22 can be switched on or off. Thus, a two-point control can be provided here, which in response to a pressure within the container 10, which here as pressure on the holding device 2, controls.

The drive device 22 may alternatively or additionally be controlled, for example, such that it only permits a maximum torque or drive torque and stops when this drive torque is exceeded. As soon as the pressure in the container drops, the motor 22 or the drive device 22 will move the first holding device upwards and thus further compress the container (as a result of which the internal pressure in the container rises again). Thus, even with this procedure, the decrease of the liquids depends on the internal pressure in the container, but more precisely there is also a volume-controlled decrease of the liquid. It would be possible to provide both pressure-dependent control mechanisms (redundant) in order to avoid bursting of the container 10 in each case.

The reference numeral 16 denotes a movement device which serves to pull off the compressed container 10 from the second holding device 4. This movement device can be arranged, for example, fixed to the first movable holding device 2. During a backward movement of the first holding device 2 downwards, this movement device comes into contact with the container 10 and pulls it at least partially from the second holding device 4.

Preferably, this movement device 16 is therefore arranged to be movable and preferably at least temporarily coupled to a movement of the first holding device 2. It would also be conceivable that the movement of the movement device is coupled only with a backward movement with the movement of the first holding device 2. Preferably, the movement device 16 abuts against the second holding device 4, or its outer circumference. However, it would also be conceivable that a separate drive for moving the movement device is provided. It would also be conceivable that the movement device is manually movable. Also, the movement device could be designed as a relative to the second holding device displaceable ring. In particular, the movement device 16 is designed as a deliverable hook.

At the in Fig. 1 As shown embodiment takes place a pressure-controlled decrease.

The reference numeral 90 schematically indicates a read-out device for reading out an identification element arranged on the container, which may, for example, be an RFID chip. Depending on the arrangement position of this identification element on the container, however, the read-out device can also be located in another area of the device 1. In the illustrated position of the readout unit (90), it would be advantageous if the RFID element is attached to the main body (10c) on the outside of the container, substantially at the same height or at a height which is still for the readout unit in terms of signal strength is acceptable. It is also possible to provide a plurality of read-out units (not shown) along the circumference of the container position and / or along the height in order to better receive a response from a transponder. It would also be conceivable for only one existing and shown in the figure readout unit (90) to mark the container in the circumferential direction, so that the operator can bring the container in a certain orientation in the circumferential direction in the holder (2, 4) and thus the Identification element always as close to the readout unit (90) is arranged. Alternatively, the container (10) in sections, preferably on the ground, have a shape which can be introduced only in a spatial orientation in the circumferential direction in the holder (2, 4), for example, that of a right triangle.

Fig. 2 shows a further embodiment of the device according to the invention. In this embodiment, the removal device 40 has a flexible conduit section 72, which can be crimped by a cross-sectional constriction element 74, which is loaded by a spring 76. The combination of this flexible line cross-section and the spring-loaded cross-sectional constriction element forms here the control device 20, which controls the removal of the liquid from the container in response to an internal pressure of the container 10 in this embodiment.

If it is desired to remove liquid, the user activates the drive means, thereby squeezing the container and increasing the internal pressure in the container 10. Due to this increased internal pressure, the pressure in the flexible pipe section 72 also increases, the cross-sectional constriction element can open and liquid emerges. As a result, in turn, the internal pressure in the container 10 decreases and due to the reduced internal pressure and the cross-sectional constriction member close the line section 72 again.

Advantageously, the force acting on the cross-sectional constriction element spring force is adjustable, so as to adjust the pressure at which liquid is dispensed.

In addition, or as a further safety device, the motor 33 may also have a torque-dependent cut-off device in order to prevent bursting of the container 10 even when faults occur on the control device 20.

If desired, this cross-sectional constriction member 74 may also be made slightly movable by the user so as to discharge a liquid (even at lower internal pressure in the container via the outlet 54 (by enlarging the cross-section of the conduit portion 72).

The reference numeral 42 here again denotes the piercing body or the piercing device, which can puncture the container closure 30. This piercing body is advantageously formed as a tube through which a liquid can flow.

Fig. 3 shows a further schematic representation of a device according to the invention. As you can see, the container is inserted here upright. The second holding device 4 has a cavity or receiving space 62, within which a line 64 for removing the liquid (but preferably also an orifice of the container 10) is arranged. This line 64 also extends here along the longitudinal direction L of the container 10. It can further be seen that, around a base body 10c of the container 10 around no housing is formed, or no wall on which this body portion 10c of the container can rest. In the embodiment shown here, the first holding device 2 is adapted to a bottom structure of the container 10. However, this is not essential.

Fig. 4 shows the device in a partially empty state of the container. In this case, initially pierces the tapping body 42 through the container closure 30 and is then introduced so far until the tapping body 42 is disposed with its entire cross section within the product or the liquid F. It is possible that with a movement of the piercing body 42 already the entire holding device 4 and the punch 4 moves downwards. Preferably, however, these two bodies are arranged stationary.

Thus, the container 10 is pressed in here by the shoulder by a movement of the holding device 2, wherein particular care is taken to ensure that in the region of the refolding 10e no product, but only air or a gas is.

By the holding device 4 and the punch, however, the mouth and also the inner part of the container shoulder remain upright. It can be seen that the holding device 4 not only receives the mouth, but also an initial region of the shoulder of the container. Accordingly, the holding device is adapted to the area 4a of the shoulder shape of the container 10 and after the impressions, the holding device or the stamp is formed in mirrored form such that the unwound distance of the container shoulder of the unwound punch shoulder 4a corresponds. Also it would be possible that the stamp shoulder the shoulder of the container (during its compression) changed in favor of a better emptying, or even in favor of a better threading. In other words, in such an embodiment, the shape of the punch shoulder is not adapted to a shape of the container shoulder but deforms it.

Furthermore, it would be possible that the unwound punch shoulder is slightly shortened to pull the outside diameter easier inward.

As already mentioned, the punch (i.e., the retainer 4) and the support shell (the first retainer 2) move relative to each other.

As mentioned above, the first holding device 2 is preferably moved and pressed against the stationary holding device 4. This has the advantage that the removal device 40 and possibly also the tap can be arranged stationarily.

Fig. 5 shows an embodiment in which the container 10 is inserted overhead. In this case, only a puncture of the piercing device 42 is required, so that a corresponding opening is created to empty as much as possible. The mouth of the container is arranged here below. A corresponding piercing device may have a cutting edge which does not extend completely circumferentially in the circumferential direction of the piercing device.

In this embodiment, the container bottom 10a is advantageously rolled into the container in order likewise to have the flanged rim at the top, so that no product puddle results within the flanged rim. In this variant, a very extensive residual emptying of the product can be achieved. However, it is disadvantageous here that the container can drip when the container 10 is removed.

Fig. 6 shows an embodiment in which the first holding device 2 has a receiving element, which is adapted in terms of its shape to a container bottom, for example on a so-called Petaloidboden. This embodiment has the advantage that the container can be kept very stable in the holding device 2.

Fig. 7 shows a further embodiment of a device according to the invention. In this embodiment, the holding device 2 on no receiving device, which is adapted to the shape of the bottom of the container. Rather, the container is pressed here in a different form. Thus, the container bottom between the first holding device 2 and the second holding device 4, or between the punch 4 and the shell 2 is transformed. In this case, the bottom and the feet of the container 10 are deformed or wrinkled so that the smallest possible cavity remains. This irregular configuration allows for the plastic material of the container. In other words, the bottom and the feet are brought into an appropriate shape by the axial deformation force, the container internal pressure and in particular by a mechanical compression in order to empty the container 10 as best as possible. However, this requires relatively high pressing forces of the drive device (and / or a strong reduction ratio).

Depending on the design of the bottom of the container can be more or less press his feet. Limiting here is the thick-walled portion in the middle of the soil. The deformation of the shoulder of the container is applied to the thus formed bottom (or immediately before it) and there is a kind of annular channel in the middle of the bottom, in which the residual liquid flows when unloading the container towards the center. The piercing device 42 advantageously protrudes to the bottom of the container.

Fig. 8 shows a further embodiment, which additionally causes a reduction in the height of the device. In this embodiment, the second holding device 4 is shorter than half the container length, for example in the range of the third container length. In addition, radially encircling projections or a collar 48 can be provided, which cause the container not only to be rolled around the fold 10e shown in the above figures, but additionally also a squeezing takes place in the region 10g of the container. In this way, as mentioned, the punch length and thus the height can be reduced. More specifically, a reduction of the length of the second holding device 4 in the longitudinal direction L of the container by almost half is possible.

Furthermore, it can be achieved in this way that the residual volume in the container is further reduced. Furthermore, with a gas in the container headspace, the liquid can be further pushed out.

Now, if the container 10 is rolled so far that the deflected container wall is present at the end of the holding device 4 or on the collar 48, usually from this collar 48 forth a wave or a fold after the other. However, if the container wall is pushed together shapeless, but this is not disturbing.

The Fig. 9a - g show several representations of containers with identification elements. At the in Fig. 9a The illustration shown illustrates in which areas such an identification element 80 can be arranged. This can be located, for example, on or in a closure 82 of the container, on a carrying handle 84 or on a wall region of the container 10 or a bottom region of the container 10. It would also be conceivable to provide a plurality of such identification elements, which are in particular RFID chips.

Fig. 9b shows a representation in which the identification element 80 is arranged on a carrying handle. This handle 84 can be snapped over an opening of the container on this means of Aufschnappmittels 94. The identification element 80 may be integrated or glued into the carrying handle 84, for example.

Fig. 9c shows a representation in which the identification element is arranged on a closure 82 of the container 10. Again, the identification element can be integrated into this closure but also about glued.

Fig. 9d shows a representation in which the identification element 80 is disposed on a bottom or on a peripheral wall of the container. Again, the identification element can be introduced or integrated. In particular, in the case of an arrangement on the wall, the identification element can also be integrated into a label attached to the container.

In addition to the use of RFID chips, other identification elements such as, in particular, bar codes or QR codes could also be used. These could for example also be printed on a wall of the container.

Fig. 9e shows a further possible arrangement for an identification element 80. Here, the identification element is arranged on a support ring which extends in an orifice region of the container 10 is located. Fig. 9f shows a more detailed representation. In this case, the identification element also has an antenna 81 which extends around the mouth 10b of the container 10 here.

Fig. 9g shows a representation to illustrate the reading of an identification element 40. This identification element 40 is arranged here on a peripheral wall of the container. The device for removing liquid here has an annular read-out device for reading out the identification element. This has the advantage that the container for the purpose of reading does not have to be arranged in rotation in the removal device. Conversely, it may also just be desired that the identification element can only be read in a precisely defined rotational position. In this case, the identification element can also be used to ensure a rotational position-appropriate arrangement of the container in the removal device.
