Description

The invention relates to a packaging system for a multi-component product preparation with a first container for holding a first product preparation component, with a second container for holding at least one second product preparation component and with a closure element which both seals the first container tightly from the environment and also has a coupling device. to couple the second container to the closure member and to provide fluid communication between the first container and the second container. Such packaging systems are usually used for the targeted mixing of fluids that are initially stored separately and are mainly used when using two- or multi-component product preparations in which the individual preparation components are not compatible with each other due to their chemical composition or only shortly before actual use are to be mixed. Such product preparations are known, inter alia, from the cosmetic, medical, food and detergent and cleaning agent sectors.

This is how the German utility model describes DE 29721872 U1 for example, an arrangement for coupling two containers with the aim of possible mixing of fluids initially stored separately in the containers. The coupling arrangement described there is used, among other things, for mixing individual components of hair dyes, the individual components being incompatible with one another and therefore having to be stored separately from one another in separate containers until they are actually used. The individual components are then mixed to form the ready-to-use hair dye immediately before use. For this purpose, the coupling arrangement has two coupling elements, each of which enables the connection of an associated container. The coupling elements each form a flow passage which is in fluid connection with the respective interior of the container. In addition, the two flow passages within the clutch assembly are aligned with one another. In addition, the clutch arrangement has a control element which is arranged in one of the flow passages so that it can be displaced between a first and second position. Depending on the respective position of the control element, the flow passages can be open or closed. In this respect, depending on the position of the control element, a flow through the flow passages and thus through the entire clutch arrangement is made possible or prevented. The flow passages are usually closed in the initial state of the clutch arrangement. To improve the sealing function, an additional plug is provided, which closes a flow passage in the initial state of the clutch arrangement. During use, the stopper is removed under the action of the displaceable control element, so that the flow passages are released for flow.

From the WO 2007/111667 A2 another system with two containers for separate storage of two container contents is described, in which the different container contents can be mixed immediately before use by means of a coupling device connecting both containers. For this purpose, the coupling device has a valve arrangement which can be moved between a closed and an open position. In the open valve position, a flow passage is released in the coupling device, which forms a fluid connection between the two containers. Thus, when the valve is in the open position, mixing of the two contents of the container is permitted.

Other packaging systems are also out WO 98/51586 A1 , EP 0 520 207 A1 , WO 2007/145773 A2 and EP 1 167 231 A1 known.

Although the above-described systems basically allow different substances to be stored separately and mixed immediately before they are actually used, they have an undesirably complicated structural design. In addition, such systems may also contain dangerous chemical substances that require careful and correct use. In such a case, an undesired mixture or the unintentional escape of the individual substances must be prevented above all.

Based on this, the object of the invention is to specify an adapter-like device for coupling two containers to enable the mixing of fluids stored separately therein, which allows simple and safe operation with a simple overall design and in particular excludes operating errors as far as possible. Furthermore, a safe method for mixing a multi-component product preparation using such a packaging system is to be specified.

In principle, the term "fluids" in the sense of the invention is understood to mean all flowable and pourable substances, i. H. not only liquid or correspondingly viscous substances but also solid bulk goods, such as powder or granules.

This object is achieved with the subject matter of patent claims 1, 13 and 14. Further embodiments and advantageous refinements are the subject matter of the dependent claims.

According to one aspect of the invention, a packaging system for a multi-component product preparation is specified, which has a first container for holding a first product preparation component, a second container for holding at least one second product preparation component and a closure element. The closure element seals the first container tightly from the environment and has a coupling device in order to couple the second container to the closure element and to create a fluid connection between the first container and the second container. The closure element comprises a closure cap which can be separated from the closure element along a predetermined breaking point in order to release the fluid connection between the first container and the second container. The closure cap is in a direction of rotation about an axis L des Closure element blocked and slidably coupled to the second container in a direction parallel to the axis L.

The advantage of the packaging system is that it is particularly safe to handle and is therefore also suitable for storing and mixing hazardous chemicals. This is achieved in particular in that the first container is initially tightly closed by means of the closure cap. Only when the first container is connected to the second container via the coupling device of the closure cap can the closure cap be separated by breaking the predetermined breaking point. The fluid held in the first container is therefore only released when it can flow into the second container. Since the closure cap is initially tightly connected to the closure element, accidental release of fluid from the first container is largely ruled out.

The predetermined breaking point is designed, for example, as an area of the closure element with a particularly small wall thickness.

This is further intensified when the closure element is non-releasably connected to the first container, for example latched to the first container, with the exclusion of its destruction. It is then not possible to separate the closure element from the first container, for example by twisting it off, and thereby accidentally release fluid. The probability of operating errors is thus greatly reduced.

According to one embodiment, the closure element and the second container have mutually corresponding threaded portions in order to couple the second container to the closure element by screwing. This represents an advantageous possibility of securely and tightly connecting the second container to the closure element and thus ultimately to the first container.

According to one embodiment, the coupling device is designed as a collar with an internal thread, which can be slipped over an edge of an opening of the second container when the first container is being coupled to the second container, the internal thread interacting with an external thread of the second container in order to connect the coupling device with connect to the second container.

This embodiment has the advantage, among other things, that a thread on the edge of the second container, which is also used for a closure element of the second container to be removed before mixing, can be used for the connection to the closure element. The second container can therefore be of particularly simple design.

According to an alternative embodiment, the closure element and the second container have mutually corresponding coupling elements which allow a relative rotation of the closure element and the second container in a value range of less than 180°.

This embodiment has the advantage that the closure element can be designed in a particularly simple manner and can be produced particularly easily in an injection molding process. For example, the coupling elements on the closure element can be designed as projections that engage in depressions on the container, the dimensions of the depressions being wider than the projections such that the closure element can be rotated through a certain angle of 180° with respect to the second container.

The ability to twist is used to separate the closure cap from the closure element at the predetermined breaking point. Since the closure cap can be secured to the second container in a blocked manner in a direction of rotation about an axis L of the closure element, twisting the closure element relative to the second container can result in the closure cap being separated. A rotation of a few degrees may be sufficient for this. In order to ensure good handling, a relative rotation by, for example, 10° to less than 180°, in particular by 30° to 90°, can be advantageous.

The blocking of the closure cap against rotation about the axis L can be achieved, for example, in that the closure cap has at least one projection which, during the coupling to the second container, interacts with at least one corresponding depression or recess on the second container in such a way that a Rotation of the cap is blocked relative to the second container. In particular, several such projections and depressions can also be provided, which are distributed over the circumference of the container or the closure cap. According to one embodiment, the sealing cap has a large number of locking teeth in its edge region, which engage in depressions on the second container.

According to one embodiment, the closure cap is covered from the environment by means of a cover element in such a way that manual access to the closure cap from the outside is prevented.

In particular, the cover element can be designed as a sleeve-shaped section of the closure element, which surrounds the closure cap radially and protrudes axially.

Such a cover element has the advantage that the closure cap cannot be removed manually. This represents a special safeguard that is advantageous when an aggressive substance is kept in the second container. In this case, the sleeve-shaped section can correspond to the collar mentioned above and have a thread which corresponds to a thread on the second container.

According to one embodiment, an edge area of the sleeve-shaped section is designed as a tamper-evident ring that breaks into several sections when the closure element is placed on the second container in such a way that the closure cap is separated from the closure element along its predetermined breaking point. In this embodiment, use is made of the fact that the closure cap and the second container approach one another during the separation of the closure cap. This approach causes the tamper evident ring to break. From the state of the tamper-evident ring, it can thus be seen whether the closure cap has possibly already been completely or partially detached and the first container is therefore no longer securely closed.

According to one embodiment, the closure element can be coupled to the second container in a liquid-tight manner. For this purpose, it has in particular at least one seal in order to ensure a liquid-tight connection to the first and/or second container.

This embodiment has the advantage that the unintentional escape of liquid before, during or after the mixing of the fluids is prevented.

According to one aspect of the invention, a method is provided for mixing a multi-component product preparation using a packaging system with a first container for holding a first product preparation component, with a second container for holding at least one second product preparation component and with a closure element which seals the first container tightly opposite the Closes the environment and has a coupling device in order to couple the second container to the closure element and to create a fluid connection between the first container and the second container, the closure element comprising a closure cap which can be separated from the closure element along a predetermined breaking point.

The method includes attaching the first container to the second container by means of the closure element, in that both corresponding threaded sections on the closure element and on the second container are attached to one another for screwing and the closure cap is coupled to the second container in a blocked manner in a direction of rotation about an axis L of the closure element becomes.

The method also includes screwing the closure element to the second container via the corresponding threaded sections and separating the closure cap blocked in the direction of rotation from the closure element at the predetermined breaking point
The method also includes the further screwing of the closure element on the second container while at the same time sliding the separated closure cap into the interior of the container and mixing the two product components in the first and/or second container using the open fluid connection between the two containers.

The procedure is particularly easy to carry out even without practice. In particular, it is largely impossible for a user of the packaging system to come into contact with components of the product preparation when carrying out the method.

Another aspect of the invention relates to an alternative method for mixing a multi-component product preparation using a packaging system with a first container for holding a first product preparation component, with a second container for holding at least one second product preparation component and with a closure element which seals the first container tightly opposite the Closes the environment and has a coupling device in order to couple the second container to the closure element and to create a fluid connection between the first container and the second container, the closure element comprising a closure cap which can be separated from the closure element along a predetermined breaking point, the method includes attaching the first container to the second container by means of the closure element, in that both corresponding coupling elements on the closure element and on the second container, which allow relative rotation of the closure element and second container in a value range of less than 180°, and the closure cap are brought into engagement locked in a direction of rotation about an axis L of the closure member is coupled to the second container.

The method also includes rotating the closure element relative to the second container via the corresponding coupling elements about the axis L, separating the closure cap, which is blocked in the direction of rotation, from the closure element at the predetermined breaking point.

The method also includes an axial relative movement between the closure element and the second container in order to push the separated closure cap into an interior space of the second container and the mixing of the two product components in the first and/or second container using the open fluid connection between the two containers.

figure 1 shows a first container 2, which is designed as a glass bottle in the illustrated embodiment and represents part of a packaging system. Alternatively, it could also be made of plastic, for example. The packaging system, which is explained in more detail with reference to the following figures, serves to accommodate a multi-component product preparation, with individual components being kept separate before the product is used. For this purpose, the packaging system has the in figure 1 shown first container 2, in which at least a first component of the product preparation is held. The first container 2 has a body 3 and a neck 30 opening into an opening 4 of the container 2 . In the area of the neck 30 there is also a thread 5 designed as an external thread and a locking ring 23 which is designed as a peripheral projection on the neck 30 .

The Figures 2a and 2b show a sectional view and a perspective view of a second container 6, together with the first container 2 according to FIG figure 1 and a closure element described in the following figures represents a packaging system. The second container 6 serves to store at least one further component of the product preparation and also to mix the components from the first container 2 and the second container 6 and to store the ready-to-use product.

The second container 6 also has a body 7 and a neck 31 opening into an opening 8 . The second container 6 is typically also made of plastic or glass.

The packaging system can be, for example, the packaging of a hair dye that is mixed from at least two components immediately before use.

In the area of the neck 31 of the second container 6 there is also a thread 9 designed as an external thread. Furthermore, on the inside of the neck 31 there is a ratchet ring 10 made up of a large number of receptacles for ratchet teeth.

In the embodiment shown, the second container 6 has a larger volume than the first container 2.

The Figures 3a to 3f show different views of a closure element 11, which initially serves to close the first container 2 and then to connect the first container 2 to the second container 6.

Figure 3a shows a side view of the closure element 11. This has a first opening 12 on one side and a second opening 13 on the opposite side. The first opening 12 is intended to be connected to the opening 4 of the first container 2 . The second opening 13 is intended to be connected to the opening 8 of the second container 6 . Furthermore, the closure element 11 has a wall 14 which has the shape of a cylinder jacket. The closure element 11 has a longitudinal axis L, which can coincide with the longitudinal axes of the containers 2, 6 in the embodiment shown. The edge area around the second opening 13 is designed as a tamper-proof ring 25, the function of which will be explained in more detail later.

Figure 3b shows a view of the closure element 11 from a perspective directed into the first opening 12 . In this view, as per the perspective view Figure 3e , It can be seen that inside the closure element 11 there is a thread 15 designed as an internal thread and a circumferential locking channel 22 . The thread 15 is designed as a thread that corresponds to the thread 5 of the first container 2 . The latching channel 22 is provided for receiving the latching ring 23 of the first container 2 .

In the Figures 3c and 3f a view of the closure element 11 looking into the second opening 13 is shown. In this view it can be seen that the closure element 11 comprises a closure cap 17 which closes a flow path from the first opening 12 to the second opening 13 . The edge of the closure cap 17 is designed as a ratchet ring 16 with a large number of ratchet teeth. The ratchet teeth are provided on the inside of the second container 6 to engage in the ratchet ring 10 .

In the sectional view in Figure 3d it can be seen that the closure cap 17 is connected to the rest of the closure element 11 via a predetermined breaking point 18, which is designed as a circumferential area with a thin material thickness.

In the sectional view in Figure 3d it can also be seen that the wall 14 of the closure element 11 is designed as a collar 19 which surrounds a second wall 32 coaxially. The thread 15 is arranged on the inside of the second wall 32 . On the inside of the first wall 14 there is also a thread 20 which is designed as an internal thread. A gap 24 is formed between the first wall 14 and the second wall 32 . A seal 21 is formed in this intermediate space 24 as a circumferential sealing lip, which is intended to seal the second container 6 against the environment in a fluid-tight manner during use.

figure 4 shows various views of the closure system 1 with the first container 2, the second container 6 and the closure element 11, which connects the first container to the second container 6.

The closure element 11 is connected to the first container 2 via the threads 5 , 15 and via the latching connection made up of the latching groove 22 and the latching ring 23 . Due to the design of the snap-in connection, which is described in detail in figure 5 is shown, once the closure element 11 has been put on, it can only be removed again from the first container 2 by force and, if necessary, by destroying the closure element 11 . The closure element 11 seals the first container 2 tightly against the environment. The first container 2 closed with the closure element 11 can therefore also be suitable for longer storage of a first component of a product preparation. In addition, the first container 2, which is non-detachably closed with the closure element 11, can be handled safely and is therefore also suitable for storing hazardous substances.

For mixing a ready-to-use product preparation, a closure, not shown in the figures, is removed from the second container 6, in particular it is originally connected to the second container 6 via the thread 9 and is unscrewed from it before preparation. Then the first container 2 closed with the closure element 11 is placed upside down on the second container 6 and the closure element 11 is connected to the second container 6 .

In the in the Figures 1 to 9 In the first embodiment shown, the closure element 11 is connected to the second container 6 by means of the thread 20 which interacts with the thread 9 of the second container 6 . The closure element 11 connected to the first container 2 is thus screwed onto the second container 6 .

In the figure 4 the packaging system 1 is shown in a first position, namely immediately after the placement of the first container 2 with the closure cap 11 on the second container 6 and thus at the beginning of the screwing process. As in figure 5 can be seen, the threads 9 and 20 are not yet meshing at this point in time. However, the collar 19 of the closure element 11 already protrudes over the neck 31 of the second container 6. In addition, it already grips the ratchet 16 in the ratchet 10 and thus fixes the cap 17 against rotation on the second container 6.

In this position, the tamper-evident ring 25 projects down to an inclined flank 26 of the neck 31 of the second container 6 . The flank 26, which has a slope directed outwards, is used to destroy the tamper-proof ring 25 when the two containers 2, 6 are connected, as will be described below. In the in the figures 4 and 5 shown first position, however, the tamper evident ring 25 is still intact.

The figures 6 and 7 show the packaging system 1 in a second position, which differs from that in figure 4 and 5 shown differs in that the closure element 11 has already been screwed to the second container 6 . As in particular in figure 7 As can be seen, the threads 9, 20 now mesh and the neck 31 of the second container 6 protrudes further into the intermediate space 24 than in the first position according to FIG figure 5 . Furthermore, the tamper evident ring 25 has already been partially destroyed by contact with the flank 26 .

As in figure 7 As can be seen, by twisting the closure element 11 relative to the second container 6 when screwing the closure element 11 onto the second container 6, the closure cap 17 fixed relative to the second container 6 was separated from the closure element 11 along the predetermined breaking point 18. In the in the figures 6 and 7 In the second position shown, the closure cap 17 is still in the neck 31 of the second container 6 and the locking ring 16 is in engagement with the locking ring 10 .

The figures 8 and 9 show the packaging system 1 in a third position, which differs from that in FIGS figures 6 and 7 shown second position differs in that the closure element 11 was screwed a little further onto the second container 6. As in figure 9 As can be seen, in this end position the uppermost edge of the neck 31 of the second container 6 is in contact with the seal 21 on its inside, so that the second container 6 is connected to the closure element 11 in a sealing manner. The closure cap 17, which was already separated in the second position, was pressed into the second container 6 by screwing the closure element 11 further onto the second container 6 and thus released a fluid connection between the first container 2 and the second container 6.

In the in the figures 8 and 9 In the third position shown, the tamper-evident ring 25 has also been further destroyed by contact with the inclined flank 26 and thus now indicates an opening of the fluid connection between the first container 2 and the second container 6 . The fluids stored in the first container 2 and the second container 6 can now be mixed with one another using the fluid connection created by the separation of the closure cap 17 .

The emptied first container 2 with the closure element 11 seated thereon can then be unscrewed from the second container 6 and disposed of. The finished product preparation is now available for further use in the second container 6 . If necessary, an applicator can be placed on the second container 6 for further use; in particular, it can be screwed onto the second container 6 using the thread 9 .

figure 10 shows a first container 2 of a second embodiment of a packaging system. The first container 2 according to the second embodiment, like that in figure 1 shown has a body 3 and a neck 30 which opens into an opening 4 of the container 2. In the area of the neck 30 there is also a thread 5 designed as an external thread and a locking ring 23 which is designed as a peripheral projection on the neck 30 .

figure 11 shows two different, mutually perpendicular sectional views of a second container 6 according to the second embodiment, together with the first container 2 according to FIG figure 10 and a closure element described in the following figures represents a packaging system. The second container 6 also has a body 7 and a neck 31 opening into an opening 8 . In the area of the neck 31 of the second container 6 there is also a thread 9 designed as an external thread.

In addition, the second container 6 has opposite projections on the inside of its neck 31 which, together with projections on the closure element, as explained below, represent corresponding coupling elements that allow a relative rotation of the closure element and the second container 6 in a value range of less than 180°.

The Figures 13a to 13f show different views of a closure element 11 according to the second embodiment, which initially serves to close the first container 2 and then to connect the first container 2 to the second container 6.

Figure 13a shows a side view of the closure element 11. This has a first opening 12 on one side and a second opening 13 on the opposite side. The first opening 12 is intended to be connected to the opening 4 of the first container 2 . The second opening 13 is intended to be connected to the opening 8 of the second container 6 . Furthermore, the closure element 11 has a wall 14 which has the shape of a cylinder jacket.

The closure element 11 has a closure cap 17 connected to the rest of the closure element 11 via a circumferential predetermined breaking point 18 .

Furthermore, the closure element has opposite projections 28 both in the region of the closure cap 17 and below it in the region of the wall 14 , which interact with the recesses 27 of the second container 6 .

Figure 13b shows a view of the closure element 11 from a perspective directed into the first opening 12 . In this view, as per the perspective view Figure 3e , It can be seen that inside the closure element 11 there is a thread 15 designed as an internal thread and a circumferential locking channel 22 . The thread 15 is designed as a thread that corresponds to the thread 5 of the first container 2 . The latching channel 22 is provided for receiving the latching ring 23 of the first container 2 .

In the Figures 3c and 3e a view of the closure element 11 looking into the second opening 13 is shown. In this view it can be seen that the closure element 11 comprises a closure cap 17 which closes a flow path from the first opening 12 to the second opening 13 .

As in particular in Figure 13f As can be seen, the projections 28 on the closure cap 17 are arranged rotated by a few degrees in relation to the projections 28 on the wall 14 . An identical projection 28 is located exactly opposite each projection 28, so that two opposite projections 28 are arranged on the closure cap 17 as well as on the wall 14.

In the Figures 14 and 15 the packaging system 1 is shown in a first position, directly before the first container 2 with the closure cap 11 is placed on the second container 6. As in FIG figure 15 As can be seen, the closure element 11 has not yet been inserted into the neck 31 of the second container 6 .

The figure 16 1 shows the packaging system 1 in a second position, in which the neck 30 of the first container 2 provided with the closure element 11 has been inserted into the neck 31 of the second container 6 in order to connect the containers 2, 6 to one another. For this purpose, the first container 2 and the second container 6 are rotated relative to one another in such a way that the projections 28 on the closure cap 17 protrude into the recesses 27 on the neck 31 of the second container 6 . The recesses 27 have a kind of L-shape, which allows the projections 28 on the closure cap 17 to penetrate into the second container 6 up to the lower end of the neck 31 . In this in figure 16 position shown, the projections 28 on the closure cap 17 are in the figure 14 with 33 designated lower portion of the recesses 27 to lie. Since this lower area 33 has approximately the same dimensions as the projections 28 on the closure cap 17, the closure cap 17 is secured against rotation on the second container 6 in this second position. Since an upper portion 34 of the recesses 27 has a larger angular extent, the rest of the closure element 11 is in an angular range relative to the second container 6, which results from the angular extent of the upper portion 34 relative to the dimensions of the projections 28 on the wall 14 results.

figure 17 shows the closure element 11 in several views in an intact state, wherein it can be seen that the projections 28 on the closure cap 17 are arranged rotated relative to the projections 28 on the wall 14. Furthermore, in figure 17 recognizable that the closure cap 17 is separated from the rest of the closure element 11 by a circumferential predetermined breaking point 18 .

The figure 18 shows the packaging system 1 in a third position, in which the closure cap 17 has been separated by rotating the first container 2, which is provided with the closure element 11, relative to the second container 6. For this purpose, the first container 2 with the closure element 11 was rotated as far relative to the second container 6 as the freedom of movement of the projections 28 on the wall 14 in the upper region 34 of the recesses 27 allows. Since the closure cap 10 was secured against rotation on the second container 6, it could not rotate, and the closure cap 17 was separated by breaking at the predetermined breaking point 18.

As in figure 19 As can be seen, the closure element 11 is now in a state in which the closure cap 17 has been separated from the rest of the closure element 11 and in which the projections 28 also lie one above the other in a line.

Since the projections 28 are now aligned in this way, it is possible to push the first container 2, which is provided with the closure element 11, even further into the neck 31 of the second container 6, since the projections 28 on the wall 14 now also pass through the lower region 33 of the Recesses 27 can penetrate.

figure 20 shows the packaging system 1 in a fourth position, in which the first container 2 provided with the closure element 11 has been pressed so far into the second container 6 that the severed closure cap 17 falls into the second container 6.

The product preparation components can then be mixed using the fluid connection that has now been established between the containers 2, 6.
