EP3013711B1 - Dispenser cartridge and dispenser arrangement - Google Patents

Description

The present invention relates to a dispensing cartridge according to the preamble of claim 1 and a dispenser assembly according to the preamble of claim 13, in which such dispenser cartridges are used.

Various methods and devices are known from the prior art for introducing different substances, for example flavoring substances or dyes, into drinks or for flavoring, coloring or adding various substances to drinks.

A very simple method is to mix the substance directly into the base liquid, whereby, however, an irreversible state is created and the amount of introduced substance is set once.

Furthermore, for example, from the US 3,463,361 a system is known in which a flavoring agent is contained in a kind of straw and the aroma is released during the sucking of liquid to this.

Furthermore, for example, from the EP 1 059 852 Systems are known in which hollow cylindrical matrix body with substances stored therein, for example, in a bottle top are used so that the liquid during pouring must flow past it and absorbs flavors.

Although these systems do not aromatize the original liquid, the entire amount of liquid flowing from the source to the user is always necessarily mixed with the substance and there is no way to vary or avoid it.

In addition, capsules for insertion into such devices, in which the substance or the flavoring agent is contained, are known from the prior art. In operation, the capsule is opened once and irreversibly and then emptied the entire amount of the substance in the liquid. This is disadvantageous, since in this way the capsule can be used only once and also the intensity of the addition of the donor substance is not adjustable.

US 2010/0187142 A1 discloses a dispensing cartridge according to the preamble of claim 1. US 2010/0154644 A1 discloses a dispenser assembly according to the preamble of claim 13. It is therefore an object of the present invention to provide a dispenser cartridge of the type mentioned, on the one hand well storable, but at the same time also allows a controllable and controllable release of the added donor substance.

This object is solved by the characterizing features of claim 1. It is provided that first and second closure means are provided which seal the openings in an initial configuration, wherein the closure means can be brought into an operating configuration in which a flow path through the enveloping element is released for the liquid.

Due to the tight closure of the openings, the donor substance inside the dispenser cartridge is stored safely and permanently and above all protected against external environmental influences. By providing a defined flow path through the dispenser cartridge, it is ensured at the same time that the flow of the liquid entering the dispenser cartridge accommodates the donor substance and exits the dispenser cartridge again, and thus this structural design of the dispenser cartridge allows control, when and how much of the donor substance gets into the fluid.

• So ist ein optimaler Schutz der Spendersubstanz dadurch gewährleistet, dass die Spenderpatrone in der Ausgangskonfiguration fluid- und/oder gasdicht gegen einen ungewollten Eintritt der Flüssigkeit und/oder fluid- und/oder gasdicht gegen einen Austritt der Spendersubstanz verschlossen ist.

Particularly advantageous embodiments of the dispenser cartridge are defined in more detail by the features of the dependent claims:

• Thus, optimal protection of the donor substance is ensured by the fact that the donor cartridge is sealed in the initial configuration fluid and / or gas-tight against unwanted entry of the liquid and / or fluid and / or gas-tight against leakage of the donor substance.

An easily produced, readily flowable and space-saving storable dispensing cartridge results from the fact that the dispenser cartridge or the casing element has a tubular, elongated, about its central longitudinal axis around rotationally symmetrical, in particular approximately hollow cylindrical shape or that the dispenser cartridge or the enveloping element than, in particular straight, hollow cylinder with triangular cross-section, preferably as an isosceles triangle with outwardly curved legs, or is designed as a polygonal profile.

Due to the features that the enveloping element has a corrugated or jagged or curved wall, wherein the inner surface, optionally also the outer surface, of the enveloping element has a wavy or serrated configuration deviating from a circular cylinder surface having a circular diameter, it results that a good throughflow through the Donor cartridge remains permanently guaranteed, as in this way, at least in the edge region always remain channels for the passage of liquid. In addition, by this shaping a rotatability of the dispenser cartridge can be prevented when the dispenser cartridge is inserted into a seat with a corresponding shape in a dispenser assembly.

According to a particularly preferred embodiment it is provided that the closure means are adjustable, whereby the inlet, the flow and the outlet of the liquid in, by the or from the central space or the donor cartridge, in particular continuously, is variable. As a result, not only by the choice of the amount of liquid flowing through the donor cartridge, but also by means contained in the donor cartridge constructive means of the entry and exit of liquid are controlled in the donor cartridge and in this way the admission of the liquid with the donor substance be adjusted accordingly.

The closure means are advantageously designed so that they are adjustable via externally actuated activation or adjusting means.

In this context, it is particularly advantageous if the closure means are reversibly adjustable in both directions, that is, opposite to one another, and in particular can be displaced linearly along the central longitudinal or central axis. Thus, the flow of the dispenser cartridge can be both increased and decreased.

It is advantageous if it is provided that, after the initial opening, the flow path or the flow rate through the central space or through the dispenser cartridge through the closure means by at least 50%, preferably by 70%, particularly preferably by 90%, compared to the maximum Passage capacity is reduced or that the openings are closed again completely tightly by the closure means after the first opening.

A structurally advantageous embodiment provides that the first and second closure means are designed as plugs or comprise plugs.

In this context, it is particularly advantageous if in the openings in each case a guide element, in particular largely or completely sunk into the interior of the central space, is arranged, wherein the stopper is mounted or arranged in each case in a central through-going recess of the guide element.

In order to ensure a good and safe adjustment of the flow of the dispenser cartridge, it is advantageous if at the outer side facing away from the center of the plugs Stellführungen, in particular recesses, are formed, which can be brought into external activation or adjusting means in, in particular mechanical, interaction or in the external activation or adjusting means are positively and / or positively applicable. This also ensures the reversible adjustability of the plug.

According to a further advantageous embodiment, it is provided that the plugs permanently in both the initial configuration and in the Operating configuration are arranged completely inside the dispenser cartridge or inside the central space. The plugs are thus components of the dispenser cartridge, which can not be incurred or dropped separately either before, during and also after use of the dispenser cartridge, but permanently remain inside the dispenser cartridge.

With regard to the donor substance itself, it is advantageous if the donor substance is present in a form in which it at least partially changes into the liquid on contact with the liquid. In this way, a reliable dosage is possible.

In this context, it is advantageous if it is provided that the at least one donor substance is soluble or dispersible in the liquid, and is selected from the group of flavorings, drugs, additives, vitamins, minerals and / or dyes, etc. But there are also other substances possible, which can bring in this way in a liquid.

However, it is particularly advantageous if the donor substance is applied to or contained in at least one separate, in particular ball, rod, thread or pin-shaped, donor element arranged in the central space. This also results in that the donor substance or the donor element is reversibly exchangeable or removable after use from the donor cartridge and instead a new donor element can be used.

A donor element in which the donor substance has a particularly good release profile results in that the donor element has a porous matrix, in particular of plastic, which defines an internal network of channels and defines pores on the exposed surface of the matrix which are in fluid communication with the channels are, wherein the pores preferably have a mean size of 20 microns to 200 microns, wherein the donor substance is in the matrix, in particular in the channels. Such an element is from the EP 1 059 852 B1 described. Between the outer surface of the dispenser element and the inner surface of the Hüllelements a permanently permeable by the liquid intermediate region is formed according to the invention, which remains at least partially always free, so that there is permanently at least one continuous open flow channel between the two openings. This will be for example supported by the special shape of the wall of the shell element by this wall is wavy or jagged. In this way, there can be no blockage of the bypass path and it is ensured that the donor substance is always fed into the liquid.

According to a further aspect of the invention there is provided a dispensing assembly for introducing a donor substance into a liquid comprising a dispenser cartridge as described above and a dispenser cap connectable to a liquid source or container for holding and storing liquid, in particular a bottle the dispensing cartridge is operably disposed in or on the dispensing attachment or is brought into operative connection with the dispensing attachment.

It is a further object of the invention to provide a dispenser assembly, with a controlled and adjustable dosage of the addition of the donor substance to the liquid is easily possible.

This object is solved by the features of claim 13. In this case, a dispenser assembly according to claim 13 is provided. The constructive separation into a main flow path and a bypass path through the dispenser cartridge ensures that not the entire part of the liquid is mixed with the donor substance or is passed through an element containing the donor substance, but the user can adjust the flow conditions and thus the dosage of the donor substance in wide areas is flexible. In addition, this ensures that the donor substance is added to the liquid only immediately before use or the exit from the arrangement and thus the mixture is always fresh. In this way, any interactions or reactions of the donor substance with the liquid are reduced or avoided altogether and the user comes with every single sip in the enjoyment of a completely fresh prepared mixture.

According to a particularly advantageous embodiment of the dispenser arrangement, it is provided that the majority of the liquid can be flowed via the main flow path or that the ratio between the liquid flow rates through the main flow path and the bypass flow can be at least 1: 1, preferably 5: 1, particularly preferably 9: 1 , is. In this way, the dispenser cartridge can be kept small and thin and a small amount of fluid that can flow through the dispenser cartridge is sufficient to pressurize the fluid with the donor substance.

Furthermore, it is advantageous if it is provided that the main flow path and the bypass path before the discharge opening are fluidly connectable and / or meet and the liquid part of the main flow path with the liquid part of the bypass path is compatible and miscible. In this way, it is ensured that only a thoroughly mixed and homogeneously displaced from the donor substance fluid exits from the discharge opening. This avoids fluctuations and the concentration of the donor substance remains at a constant and reliably adjustable level. According to the invention, a mixing chamber arranged downstream of the dispensing opening and upstream of the dispensing cartridge can be formed or formed in the dispensing attachment, into which opening the main flow path and the bypass path. In this way, a defined space is formed, in which both flow paths necessarily combine and must mix before reaching the discharge opening. This guarantees optimum homogenization. The arrangement according to the invention also results from the fact that the main flow path is arranged spatially outside around the bypass path, surrounding it at least in sections, in particular on all sides, in particular in the form of a plurality of separate channels or in the form of a substantially ring-shaped or cylinder jacket-shaped channel. In addition, this design results in a good mixing in the mixing chamber.

For reliably opening and adjusting the flow is advantageously provided that the dispenser attachment activating or adjusting means for acting on the closure means, in particular on the plug, through which the opening of the dispenser cartridge and / or the adjustment of the flow rate through the bypass path is effected ,

A structurally particularly practical dispenser arrangement results from the fact that the dispenser attachment comprises a base unit and an activation unit which can be adjusted to the base unit, mechanical activation or adjustment means acting on the closure means and for opening the dispenser cartridge and thus in both the base unit and the activation unit are provided for opening the bypass path. Such a device is also light and easy to use.

In this context, it is particularly advantageous if it is provided that in the base unit, a first seat for the dispenser cartridge is formed, wherein at its distal end portion of the dispensing opening, a first activation or setting means for opening the first plug of the dispenser cartridge, in particular a short the first pin is arranged, and in that in the activation unit, a second seat for the opposite end of the donor cartridge is formed, wherein at its end near the discharge opening a second activation or adjusting means for opening the second plug, in particular a short second bolt is arranged , As a result, the dispenser cartridge can also be inserted easily and quickly into the dispenser arrangement, where it assumes a secure and central position protected on all sides.

The first seat is advantageously designed so that it comprises a hollow cylindrical part which extends in operation along the longitudinal axis down to the liquid source. The inner surface of the first seat or the hollow cylindrical part is formed opposite or corresponding to the outer shape of the Hüllelements, in particular corrugated or serrated, whereby a safeguard against rotation of the donor cartridge is achieved in the first seat. The inner surface of the second seat is preferably smooth, in particular circular cylindrical, formed, whereby a rotation of the dispenser cartridge in the second seat is possible and thus a rotation of the activation unit to the base unit with inserted dispenser cartridge is possible.

For reliable activation of the donor cartridge and to open the bypass path, it is advantageously provided that the base unit and the activation unit are mutually spaced adjustable, in particular rotatable by a thread, whereby the linear distance of the first activation or adjusting means to the second activation or Adjusting means is changeable, whereby by a Reducing the distance is an impression of the plug inside the dispenser cartridge is effected.

A secure adjustability and adjustability of the concentration of the donor substance in the liquid advantageously results from the fact that the plugs are displaceable in each case by the same path or towards each other.

Structurally, it is advantageous in this context if the bolts are dimensioned so that they force and / or positively engage in the recesses of the plug, resulting in a good reversible adjustability.

In this context, it is further advantageous if, by increasing the linear distance of the first activating or adjusting means to the second activating or adjusting means, a movement of the closure means or the plug in the direction of its original position is effected, in particular one at least 50th %, preferably by 70%, particularly preferably by 90% compared to the maximum passage capacity reduced flowability, preferably an almost complete fluid-tight closeability of the dispenser cartridge.

In order to avoid over-rotation and to specify a maximum lower and upper limit, it is possible for a stop to limit the maximum relative movement of the base unit to the activation unit to be formed.

A very special advantage for the user results from the fact that the dispenser cartridge is reversibly interchangeable inserted into the dispenser assembly.

If it is provided that the dispenser attachment, in particular the base unit, has a thread, preferably an internal thread, and can be screwed onto a bottle, in particular reversibly, the dispenser arrangement can be screwed reversibly onto conventional beverage bottles, for example PET mineral water bottles, in this manner or is the bottle and the liquid contained therein replaceable at any time.

In order to prevent unwanted leakage of the liquid, it is advantageous if a closure unit is provided, which is in particular mounted reversibly adjustable to the activation unit, through which the bypass path and optionally also the main flow path can be closed. On the one hand, it is possible to block both flow paths, alternatively it may also be advantageous to perform only the bypass path closable and to keep the main flow path permanently open to ensure the flow of pure, not enriched with donor liquid.

The closure unit can also be designed such that the mixing chamber is formed by lifting the closure unit of the activation unit.

In Fig. 1 a donor cartridge 1 according to the invention is shown in an exploded view. The dispensing cartridge 1 comprises a tubular casing element 2 with a continuous central space 3 and with two openings 11a, 11b provided on the opposite sides of the casing element 2. In this way, liquid can enter through the first opening 11 a in the central space 3, this flow through completely and leave on the opposite side through the second opening 11 b, the enveloping element 2 again. The sheath element 2 has an elongated configuration and is arranged rotationally symmetrically about a central longitudinal axis 5. It has approximately the shape of a hollow cylinder, but with a corrugated wall. The wall thickness is small compared to the length, but sufficient to the envelope element 2 to give an integral stability. The enveloping element 2 is made of, preferably transparent, plastic material.

In the central space 3, a donor substance is provided which, when in contact with the liquid, can at least partially pass into the liquid. This donor substance is ideally soluble or dispersible in the liquid. As donor substances are flavorings, drugs, various additives, vitamins, minerals, dyes or other substances in question, which one would like to bring into the liquid.

The donor substance can be present in different ways in the central space 3. In the present case of Fig. 1 the donor substance is on a separate, rod-shaped donor element 15. This donor element 15 has a porous matrix of a polymeric material with an internal network of channels and pores on its surface, the donor substance being incorporated in this matrix. Upon contact with the liquid, the donor substance is then washed out in small quantities and passes into the liquid.

Like from the FIGS. 5, 6 and 7 As can be seen, the dispenser element 15 may have different shapes and cross sections. In Fig. 5 it has the shape of a cuboid, in Fig. 5 it has a cross-shaped cross-section and in Fig. 7 a cylindrical shape. The dispenser element 15 is present as an integral part of the dispenser cartridge 1 and is not removable from this.

Between the outer surface of the dispenser element 15 and the inner surface 6 of the Hüllelements 2 remains a permanently open and durchströmbarer intermediate region formed, can flow through the liquid. In the FIGS. 5, 6 and 7 These intermediate areas are characterized as flow channels 16. In the embodiment of Fig. 7 closes the cylindrical dispenser element 15 almost tightly with the radially innermost wall parts of the Hüllelements 2 from, however, it remain permanently formed by the wavy configuration throughflow channels 16. In this way, the liquid can flow through the dispenser cartridge 1 permanently and effectively take up and take away the donor substance.

Fig. 7a shows an alternative embodiment of the dispenser cartridge 1 in cross section. The enveloping element 2 or the dispensing cartridge 1 is designed as a straight hollow cylinder and has a triangular outer contour and a likewise triangular inner contour. The corners of the envelope formed as an isosceles triangle 2 are rounded and the legs of the envelope element 2 shown in cross-section or the side surfaces or the wall of the donor cartridge 1 are curved outwardly.

Alternatively, the enveloping element 2 or the dispensing cartridge 1 may also be triangular, preferably designed as an isosceles triangle, or the dispensing cartridge may be in the form of a hollow polygonal profile in the sense of DIN 32711 (P3G) and DIN 32712 (P4C).

The openings 11a and 11b are closed or closable by first and second closure means 4a and 4b. In the present embodiment, the closure means 4a, 4b each comprise a guide element 9a, 9b and a stopper 8a, 8b. The guide element 9a, 9b is inserted into the corresponding opening 11a, 11b and sunk into the interior of the central space 3. Each guide element 9a, 9b has a central recess 12a, 12b which completely penetrates the guide element 9a, 9b. In this recess 12a, 12b, the plug 8a, 8b is then inserted, in such a way that the plug 8a, 8b with the respective bottom of the guide member 9a, 9b flush terminates.

In Fig. 3 the donor cartridge 1 is shown in its closed initial configuration, in which the plugs 8a, 8b are inserted into the central recesses 12a, 12b of the guide elements 9a, 9b and thus constitute a fluid and gas-tight barrier and both the entry of the liquid into the central space 3 and effectively prevent the possible leakage of the donor substance from the donor cartridge 1. In this configuration, the donor cartridges 1 are sold and are long shelf life, since the donor substance is well protected against environmental influences.

In Fig. 4 the donor cartridge 1 is shown in an open operating configuration. Here, a flow path for the liquid passes through the central space 3 on the dispenser element 15. This flow path is released by an adjustment of the closure means 4a, 4b, wherein in Fig. 4 the two plugs 8a, 8b are displaced into the interior of the central space 3 and no longer sit in the guide elements 9a, 9b. Thus, liquid can penetrate through the central recesses 12, 12b into the interior of the central space 3 and exit again.

The closure means 4a, 4b, in the present case, more specifically, the plugs 8a, 8b, are, as in FIG Fig. 2 shown, via externally operable activation or adjusting means 27a, 27b adjustable. First, the adjusting means 27a, 27b engage in the respective Outer sides 13a, 13b of the plugs 8a, 8b formed adjusting guides 14a, 14b and move the plugs 8a, 8b in this way along the central longitudinal axis 5 linearly in the central space 3. Ideally, the adjusting means 27a, 27b non-positively and / or positively, So fit exactly with a press fit in the actuator guides 14a, 14b used so that a counter-directional movement is possible and the plug 8a, 8b are again pulled outward. In this way, the flow path through the central space 3 is again reduced or the openings 11a, 11b or the central recesses 12a, 12b are closed at least partially, possibly even completely.

The dispenser cartridge 1 is designed both constructively and functionally to be used and used in a corresponding dispenser assembly 20. Such a dispenser assembly 20 comprises a dispenser attachment 21, which is connected to a liquid source or a container for receiving and storing liquid, for example a bottle or the like, or can be connected. Furthermore, the dispenser assembly 20 comprises the dispenser cartridge 1, which is operably arranged in or on the dispenser attachment 21 or can be brought into functional operative connection with the dispenser attachment 21 so that the liquid flowing through the dispenser attachment 21 can receive donor substance from the dispenser cartridge 1.

In the following FIGS. 8 to 15 is a particularly advantageous, but not limiting embodiment of a dispenser assembly 20 according to the invention for introducing a donor substance shown in a liquid. In this case, the dispenser arrangement 20 comprises a dispenser attachment 21 through which a liquid can flow from a container or a liquid source, the liquid being able to be brought to a dispensing opening 23. In this way, the liquid or mixture reaches the user or consumer.

Furthermore, the dispenser assembly 20 includes a dispenser cartridge 1 inserted therein, which is constructed substantially as in Figs Fig. 1 to 7 described, and which is operable and functionally connected to the dispenser attachment 21. In this case, a defined main flow path 24 is formed for the liquid in the dispenser assembly 20, which extends from the source in the direction of the discharge opening 23, avoiding the dispenser cartridge 1 or on the dispenser cartridge 1. In addition, a defined by the main flow path 24 fluidly defined bypass path 25 is formed by the dispensing cartridge 1 by contacting the dispenser element 15th and also receiving at least a portion of the donor substance from the fluid source toward the discharge port 23.

The majority of the liquid flows through the main flow path 24, ie more than 50%. However, the amount is adjustable and depends inter alia on the donor substance to be supplied and the desired concentration. It is easily possible to increase the ratio of the quantities of liquid between the main flow path 24 and the bypass path 25, for example to at least 5: 1 or 9: 1.

In Fig. 8 a particularly advantageous embodiment of a dispenser assembly 20 is shown. The donor cartridge 1 corresponds to the donor cartridge of Fig. 1 to 4 , The dispenser attachment 21 comprises a base unit 28, an activation unit 29 and a closure unit 31 as basic components.

The base unit 28 has an internal thread 32 with which the dispenser attachment 21 can be screwed onto a bottle. The base unit 28 further comprises a first seat 30a for the dispensing cartridge 1. This seat 30a comprises a hollow cylindrical part 38 which extends downwards along the longitudinal axis 5 to the liquid source. The inner surface of the first seat 30a or of the hollow cylindrical part 38 is formed opposite or corresponding to the outer shape of the enveloping element 2 ( Fig. 12 ). The transmitter cartridge 1 is thereby secured against rotation in the base unit 28 or in the first seat 30a or in the hollow cylindrical part 38. In the lowermost end region is a grid element 39 (FIG. Fig. 12 ), which has a central, upwardly directed bolt 27a. This pin 27a acts as the first activation or setting means 27a and engages in the setting guide 14a of the stopper 8a of the dispensing cartridge 1.

In the upper region of the base unit 28, a number of passage openings 33 are provided, which are arranged in a circle around the dispensing cartridge 1. This is also in detail in Fig. 11 recognizable, in which a section along the section line XI of the activation unit 29 in the direction of the base unit 28 is shown. Recognizable are the annularly arranged passage openings 33 and the view down on the first pin 27 a. In Fig. 11 For clarity, the dispenser cartridge 1 has been omitted.

Fig. 12 shows the section along the section line XII through the grid element 39, which carries the first pin 27 a centrally and supports.

The activation unit 29 connects to the top of the base unit 28 and is relative to this adjustable or rotatably mounted via a thread 40. That way the distance between the base unit 28 and the activation unit 29 changes. The activation unit 29 comprises as a substantial element a second seat 30b for the opposite end of the dispenser cartridge 1. Again, a grating element, in particular identical to the first grating element 39, is provided which carries a second pin 27b pointing downwards towards the base unit 28 is aligned. The inner surface of the second seat 30b is circular cylindrical ( Fig. 13 ). As a result, the dispenser cartridge 1 can rotate or rotate in or relative to the second seat 30b.

The activation unit 29 as well as the base unit 28 is completely permeable by the liquid. Thus, the liquid can enter below through inlet openings 34. This is in detail in Fig. 13 shown, which is here the section according to the section line XIII, viewed from the base unit 28 to the activation unit 29. Visible are the slot-shaped inflow openings 34 which are arranged around the donor cartridge 1, not shown, and the centrally arranged pin 27b ,

Accordingly, during operation, the dispenser cartridge 1 is seated both in the first seat 30a and in the second seat 30b and is held by the base unit 28 and the activation unit 29 and enclosed on all sides.

As a further component, the dispenser arrangement 20 also includes the closure unit 31. This serves to close the by-pass path 25 and optionally also the main flow path 24. The dispensing openings 23 are formed in the closure unit 31. These are shown in more detail in Fig. 14 in which a section according to the section line XIV is shown from below. The closure unit 31 is linearly movable up and down over a number of webs 36 which are slidably mounted in guides 37 of the activation unit 29 and thus suitable for closing the flow paths.

In Fig. 15 the individual elements are shown in assembled condition. At the bottom, the outside of the first seat 30a including hollow cylindrical part 38 can be seen, which represents the lower part of the base unit 28. The activation unit 29 is then arranged at the top and then the closure unit 31 with the discharge openings 23 again. To facilitate easy drinking, the diameters of the components taper from the base unit 28 via the activation unit 29 to the closure unit 31, the diameter of the uppermost unit Area of the closure unit 31 corresponds to the diameter of a conventional bottle mouthpiece.

Fig. 8 shows a cross-section through a particularly advantageous embodiment of a dispenser assembly 20, in a position in which the dispenser cartridge 1 has indeed been activated and opened, but the closure unit 31 is still closed. The reference numeral 24 designates the main flow path, which can initially freely flow through a space 41 of the base unit 28 and leaves the base unit 28 through the throughflow openings 33, passes through the inflow openings 34 into the activation unit 29, flows upwards through the space 42, and the dispenser assembly 20 exits through the dispensing openings 23. In the present embodiment, the discharge openings 23 are not closable by the closure unit 31, but permanently open. In this way, therefore, the pure liquid from the source can permanently flow through the dispenser assembly 20 and exit. However, it would be easily possible to design the dispenser assembly 20 in such a way that the closure unit 31 also blocks the main flow path 24 by, for example, shifting the dispensing openings 23 further inwards, whereby the web of the activation unit 29 closes them.

The reference numeral 25 denotes the bypass path which passes through the dispenser cartridge 1. In this case, the liquid absorbs donor substance and exits from the central recess 12b from the dispensing cartridge 1 and into an annular space 43, which is subdivided by the grating element 39 into areas. However, this annular space 43 is closed by the closure unit 31, whereby the liquid can indeed pass through the dispenser cartridge 1, but can not leave the dispenser assembly 20 and in particular can not connect to the main flow path 24. In this position, therefore, only pure liquid reaches the consumer.

In Fig. 9 For example, the dispenser assembly 20 is shown in a position where the closure unit 31 has been opened. At the flow paths of the bypass path 25 and the main flow path 24 through the dispenser assembly 20, nothing changes at first. However, by displacing the shutter unit 31 relative to the activation unit 29, a mixing chamber 26 is formed downstream of the discharge openings 23 and upstream of the mouth end portions of the main flow path 24 and the bypass path 25. The main flow path 24 discharges from the space 42 into the mixing chamber 26 and can be distributed there. Likewise, the bypass passage 25 opens from the annular space 43 into the mixing chamber 26 and can also be distributed there. In the mixing chamber 26, the two streams are mixed and the pure liquid mixes with the liquid added by the donor substance. The thus mixed streams may then leave the mixing chamber 26 via the discharge openings 23.

In the Fig. 8 and 9 the dispenser cartridge 1 is shown in each case in a maximum open position, in which the flow path through the dispenser assembly 1 is maximally open, that is, the plugs 8a, 8b are displaced maximally inward into the central space 3. In this way, the largest possible amount of donor substance is absorbed into the liquid.

In Fig. 10 a position of the dispenser assembly 20 is shown in which the mixing chamber 26 is formed, that is, the closure unit 31 is opened, in which, however, the flow path through the dispensing cartridge 1 is reduced. This is caused by a rotation of the activation unit 29 in comparison to the base unit 28 (indicated by the arrow), whereby a gap region 44 recognizable between these units is formed. This increases the linear distance of the two bolts 27a, 27b to each other. Due to the fact that the bolt 27b engages in the plug 8b with clamping and snug fit, the bolt 27b carries the plug 8b upward when the activating unit 29 is displaced upward. In this way, the plug 8b reduces the central recess 12b and thus reduces the escape of the liquid from the dispensing cartridge 1. In Fig. 10 the outlet is almost completely prevented, since the plug 8b already almost tight against the central recess 12b. Although complete closure is possible, in practice the flow rate is reduced by at least 50%, in particular cases at least 70% or at least 90%, compared to the maximum possible flow rate at full aperture, so there is always some residual flow and it remains always some liquid enriched with donor substance passes through the dispenser cartridge 1 in the direction of the annular space 43 and the mixing chamber 26. In Fig. 10 the bypass path 25 is thus largely closed and only a very small amount of donor substance passes into the mixing space 26 and subsequently to the discharge openings 23. By rotation of the activation unit 29, as indicated by the arrow in FIG Fig. 10 represented, relative to the base unit 28 and the associated linear enlargement or reduction of the distance of the bolts 27a, 27b to each other can thus adjust the content of donor substance in the dispensing device 20 leaving liquid in wide ranges or regulate.

As an alternative to the above-mentioned construction, the inner circumference of the hollow cylindrical part 38 in the base unit 28 may be an inside smooth, circular cylindrical one Have cross-section. The dispenser cartridge 1 can be secured in the activation unit 29 by opposite or corresponding formation of the inner periphery of the second seat 30b to the outer shape of the enveloping element 2 against rotation. Alternatively, the inner circumference of the second seat 30b may also have an inner smooth, circular cylindrical cross section, so that the dispenser cartridge 1 can rotate about its longitudinal axis both in the first seat 30a and in the second seat 30b.

• Im vorliegenden Beispiel wird eine Spenderandordnung 20 beschrieben, die als Flaschenaufsatz, der auf eine Trinkflasche, die mit reinem Wasser oder Mineralwasser gefüllt ist, aufgeschraubt ist, ausgestaltet ist.

Based on a preferred embodiment, the functionality or the practical application of the dispenser assembly 20 will now be described by way of example:

• In the present example, a donor rim 20 is described, which is designed as a bottle cap, which is screwed onto a drinking bottle, which is filled with pure water or mineral water, screwed.

First, the base unit 28 is placed with the thread 32 on the external thread of the bottle. The first seat 30a extends into the interior of the bottle, wherein the seat 30a is above the liquid level. It is thereby excluded that donor substance penetrates into the liquid.

In a next step, a sealed dispensing cartridge 1 is inserted into the base unit 28. As a donor substance, for example, a flavoring agent is used in the present case. The insertion and the secure hold are facilitated by the fact that both the dispenser cartridge 1 and the corresponding recess or the first seat 30a have a corresponding corrugated shape. In this way, the donor cartridge 1 is also secured against rotation.

In a further step, the activation unit 29 is placed on the base unit 28 and screwed by rotation over the thread 40 down. This reduces the distance between the bolts 27a and 27b and both plugs 8a and 8b are pushed inwardly by a perceptible click. The dispenser cartridge 1 is thus activated and in the open operating configuration in which there is a flow path therethrough.

In a next step, the closure unit 31 is opened by lifting relative to the activation unit 29, whereby the mixing chamber 26 is formed and all flow paths are opened.

When the bottle is tilted, the water from the bottle enters the mixing chamber 26 both through the main flow path 24 and into the mixing chamber 26 as well as through the bypass path 25 through the dispensing cartridge 1. In this position, the bypass flow 25 takes the maximum amount of flavoring and you can thus remove a flavored water from the discharge openings 23.

If you want to reduce the amount of flavor, so you twisted the activation unit 29 relative to the base unit 28 upwards, which is how in Fig. 10 the bypass flow 25 decreases and the amount of flavoring decreases.

If you want to drink pure water, so the bypass 25 can be completely closed by closing the closure unit 31.
