Definitions

• the invention relates to a packaging unit for two substances to be stored separately from one another and to be mixed before use, in particular for a liquid and a powdery substance.
• the invention comprises a first container and a second container which is movably suspended in the neck of the first container. The second container is moved by screwing on the closure cap of the first container and opened in the process.
• the present invention encompasses
• a closure cap that extends across the opening area.
• Packing units of this type are required in order to be able to keep substances which are mixed only stable for a short time between the time of manufacture and use by the end user over a longer period of time in accordance with the specified mixing ratio.
• the individual substances can be kept for a sufficiently long time, so that normal transport and storage times are unproblematic. Possibly.
• expiry dates must be observed.
• the use of such packaging units enables the end user to produce the mixtures themselves immediately before use, so that he is independent of the pharmacist, who would otherwise have to mix the preparations for one or a small number of applications.
• Packaging units of this type are u. a. have become known from European patent applications 0 093 090, 0 344 849, 0 577 200 and 0 599 189.
• the bottom of the second container inserted into the opening area of the first container is at least partially separated out by actuating the closure cap by means of a sharp object, so that the powder of the second container can be introduced into the liquid of the first container and the substances can be mixed .
• the translational movement of the sharp object in the direction of and through the bottom of the second container is brought about by a translatory or rotating movement of the closure cap after a locking ring has been removed, which prevents unwanted movement of the closure cap and thus inadvertent opening of the second container ,
• the known packaging units have the disadvantage that the opening of the second container is only possible by actuating the closure cap which destroys the material, and there is always the risk that smaller fragments arise which are separated from the second container and / or lid and fall into the mixture. Even if the consumption of such fragments is harmless to the health of the end user, they are perceived as unpleasant and annoying.
• Another disadvantage is that in some embodiments the separated bottom remains connected to the second container via a bridge. In these cases, when pouring liquid, the bottom can be moved back into the bottle neck and close it.
• Another disadvantage of the known packaging unit is that the closure cap simultaneously serves as a closure for the second container and the first container.
• the packaging units must therefore be filled with liquid and powder be carried out immediately in succession.
• the second containers cannot be filled separately from the first container in terms of location and time, because they cannot be closed independently and can be transported and stored as a separate product.
• packaging units are only suitable for producing a single portion of the mixture, because the cap is not designed to reliably re-close the first container after the securing ring has been removed.
• Such packaging units are considerably less economical than those with which quantities of mixtures can be produced which comprise a number of individual portions corresponding to the shelf life of the mixture.
• the invention is based on the object of avoiding the disadvantages of the known packaging units and of proposing an alternative which is inexpensive to manufacture and which can be handled by the end user without any problems.

• the constriction is preferably designed as a ring running around the periphery of the bottle neck. However, it can also be designed in the form of one or more point elevations, edges with cutouts, etc.

• An annular, peripheral circumferential constriction is preferred, particularly preferred one that is designed such that it can perform a function that completely seals off the second container. It can also be designed as an interference fit with respect to the second container.
• the top edge of the throat may serve to limit the downward movement of the second container.
• means are attached to the second container which can rest on the upper edge.
• the bottle neck has no additional constriction, but the bottle neck itself takes over the function of the same (bottle neck acting as a constriction), in particular the function of a sealing point. The function the top edge of the bottleneck then takes over the top edge of the bottle neck.
• a bottle neck with a low height is advantageous. Therefore, within the scope of the present invention, in principle, the same can be replaced with a bottleneck acting as a constriction in every embodiment with a constriction.
• the term “bottleneck” with a constriction is mainly used in this description. Unless otherwise apparent from the context, the term constriction also stands for a bottleneck that acts as a constriction. However, preferred are embodiments with a constriction independently formed in the bottle neck.
• the second container is such that when the packaging unit is closed for the first time it is located in the neck of the first container, where it sits in the narrow neck of the bottle neck so that it sits firmly on the one hand but can be moved axially on the other.

• the lid extends from above into the middle part of the second container, so that the second container is firmly closed.
• the lid is clamped in the second container.
• the lid can have flange-like extensions which are designed such that, when the second container is in the closed state, they pass through the above-mentioned recesses in the upper part at their bottom end and lie above the constriction of the first container or rest on the top thereof. That in these embodiments, the lid sits directly on the middle part, while the upper part of the second container extends over it.
• the outside of the cup-like cover lies sealingly against the inside of the second container, preferably at the level of the middle part.
• cutouts serve briefly as an air outlet path for air which is displaced from the interior of the second container during the closing process.
• This lower area of the outside of the cup-like cover, which is provided with recesses, can also be described as an area with a smaller outer diameter, on which webs are formed which extend in the axial direction, that is to say parallel to the height of the cover, from the bottom to the lower edge of the sealing area , A ring circumferentially surrounding the webs would then have the same inside diameter as the outside diameter of the sealing area.

• the sealing area of the lid and the sealing area of the inner casing of the second container can have complementary locking means, e.g. in the form of an annular, peripheral groove and tongue.
• Wings can be arranged on the outside of the bottom of the second container, which prevent the second container from inadvertently closing its opening area or neck when the first container is emptied.

• They can be designed individually or in pairs. A pair or two pairs which are at right angles to one another are preferably formed.
• the closure cap is designed such that it comprises an outer cylinder with an internal screw thread and an inner cylinder integrally molded thereon with a closed bottom region.
• the inner cylinder engages in the opening area of the first container and lies against the upper end of the cylindrical upper part of the second container.
• the second container with its bead-like thickened central part or from the point of its largest outside diameter, to be held non-positively in the cylindrical constriction of the first container.
• the cap By turning the cap into the first container, the second container is moved into the abdominal area of the first container.
• the lid due to its flange-like extensions, hangs on the constriction of the first container, so that the lid is released from the clamping and closing position.
• the opened second container can now fall into the belly of the first container. The substance of the second container is thus released for mixing with the substance of the first container.
• a cylindrical extension can be formed on the inner cylinder of the closure cap, which engages non-positively from above in the cup-like region of the lid of the second container during the downward movement of the closure cap. If the cover is then unscrewed and removed from the first container, it takes the cup-like cover of the second container with it.
• the cylindrical extension on its outside and the cup-like cover on its inside have complementary locking means, for example in the form of a circumferential tongue and groove or the corresponding two components of push buttons and the like.
• the groove-like peripheral ring or the groove-like recess can be formed on the inside of the cup-like part of the lid and the complementary locking means on the outside of the cylindrical extension or vice versa.

• the upper part of the second container terminates with one or more flange-like extensions which, like the extensions of the cup-like cover, point outwards.
• these are separated from one another by the aforementioned recesses. But it can also be formed only a single peripheral circumferential extension or flange. The recesses then penetrate this peripheral flange. If the container is now moved downwards, the sealing middle part again passes the constriction. However, the second container no longer falls into the first container, but is held by the extensions or the flange from the top of the constriction.
• the recesses in the upper part of the second container are used.
• the recesses are higher than the height of the constriction. This ensures that in this position the inside of the first container can communicate with the outside after the lid and the cap have been removed.
• the communication path leads from the inside of the first container to the outside of the lower part and the middle part of the second container through the recesses into the opening area of the first container. So that this communication path remains undisturbed even when the first container is moved, for example tilted, it is advantageous if at least the upper region of the outside of the upper part of the second container has a similarly large outer diameter as its middle region.
• a second bead-like thickening may be formed.
• the second container is held in the open end position by this region in the opening region so that it does not change its position relative to the first container when the first container is moved.
• the area of the upper part with a larger outside diameter and the area of the middle area, which also has a larger outside diameter than the other areas of the second container, can be separated by an area with a smaller outside diameter. The two areas can merge into one another even if the outside diameter remains the same.
• the last variant requires a consistently greater effort to push the second container through the constriction of the first container than the variant mentioned first.
• the cover when the cap moves downward, the cover can first snap into its cylindrical extension before the container is pushed into the end position. If the closure cap is opened, it takes the lid with it without releasing the container from its end position, since the positive connection between the lid and the second container is less than that between the second container and the first container.
• the lid in which the second container is to remain in the bottle neck, that is to say carries a flange or extensions at its upper end, the lid can also only snap into the cylindrical extension when the end position of the second container has been reached.
• the lid preferably has latching lugs on the inside of its cup-like upper part, which engage in the corresponding groove on the outside of the cylindrical extension or vice versa.
• the second container has at least one barb-like means on the outside of its lower part, in addition to or instead of the bead or the peripherally circumferential region which functions as a seal and has the largest outside diameter.
• This locking means is preferably designed in the form of a wedge, the tapering side of which extends downward to the bottom of the container and the upper side of which is designed as an edge which is perpendicular or approximately perpendicular to the casing of the second container.
• the lid itself can engage with its top in the cylindrical extension of the closure cap, or the closure cap itself forms the cylindrical cover.
• the latter is preferred.
• the middle part and upper part of the second container can be a single element, for example with a smooth outer jacket.
• the outer diameter of the middle part and / or the upper part of the second container is smaller than the inner diameter of the constriction, so that this part of the second container can pass the constriction without friction.
• the height of the second container from the top edge of the barb-like means to the top edge of the container neck of the second container is preferably less than the height from the bottom edge of the constriction to the top edge of the container neck of the first container.

Then the cap is screwed on tightly.
• closure cap If the closure cap is now opened, the movement of the second container via the positive connection of its lid or directly through the closure cap is carried upwards until the barb-like means of the lower part hangs from below at the narrow point. If the closure cap is opened further, its connection to the second container is released (in the case of embodiments with a separate cover, taking it with it) and the second container falls into the first container.
• the packaging unit according to the invention differs from the previously known packaging units advantageously, inter alia, in that a separately made lid can be provided for the second container, so that the second container can be filled separately and in space and time and stored and transported separately from the first container , To produce the mixture, the lid is removed from the second container in a non-destructive manner, so that no fragments of the lid or container material arise and can get into the mixture. After the second container has been moved from its original position, the mixture can easily be removed in portions and the packaging unit reliably closed.
