DETAILED DESCRIPTION

[0035] FIG. 1 shows an example of a combined storage, dosing and mixing device 1, comprising a first compartment 2 and a second compartment 3 and a dosing section 4 between the first compartment 2 and the second compartment 3. The first compartment 2 comprises a first tubular body 5 with a cover 6 screwed onto the first tubular body 5, and the second compartment 3 comprises a second tubular body 7 with a cup 8 screwed onto the second tubular body 7. The dosing section 4 comprises a third tubular body 9, onto which the first tubular body 5 and the second tubular body 7 is screwed. Furthermore, the dosing section 4 comprises a translatory movable slider 10 adjacent to the first compartment 2 and a pivotally movable flap 11 adjacent to the second compartment 3. The flap 11 is pivotally mounted in the third tubular body 9 by means of a first pivot 12.

[0036] The first tubular body 5, the cover 6, the upper wall of the third tubular body 9 of the dosing section 4 and the slider 10 (in its closed position) encompass a first container space A. The second tubular body 7, the cup 8, the lower wall of the third tubular body 9 of the dosing section 4 and the flap 11 (in its closed position) encompass a second container space B. And the third tubular body 9 of the dosing section 4, the slider 10 and the flap 11 enclose a dosing space C. Accordingly, the dosing space C is arranged between the slider 10 and the flap 11.

[0037] One should note that the concrete construction of the combined storage, dosing and mixing device 1 shown in FIG. 1 is no necessary condition for the invention. In contrast, the first compartment 2, the second compartment 3 and the dosing section 4 may be shaped differently and may be assembled in another way.

[0038] For example, the upper, first compartment 2 may be shaped like a bottle without a separate cover and having its own lower wall bordering the first container space A. The cover 6 may have a hook 13 like shown in FIG. 1 or not. The first tubular body 5 may be attached to the cover 6 and/or to the third tubular body 9 in another way than screwed. For example, the parts may be mounted together by snap fit connections or may be glued or welded together.

[0039] Basically the same counts for the lower, second compartment 3, which may be shaped like a bottle as well. In this case, the cup 8 may be omitted or may be mounted onto the bottom of said bottle. The bottle may also have its own upper wall bordering the second container space B. The second tubular body 7 may be attached to the cup 8 and/or to the third tubular body 9 in another way than screwed. For example, the parts may be mounted together by snap fit connections or may be glued or welded together as well.

[0040] Although the cup 8 and the hook 13 are no necessary parts of the invention they are nevertheless useful. By means of the hook 13 the device 1 may be stored in hanging position. For example, it may be mounted on the frame of a baby buggy. By means of the cup 8 the liquid contained in the second container space B may be enjoined in a comfortable way.

[0041] Next, further parts of the dosing section 4 are described. The dosing section 4, apart from the parts described above, comprises actuating means 14 comprising an operating block 15, which is slidably mounted in the third tubular body 9 and may horizontally be moved in the position of the device 1 shown in FIG. 1. In the example shown in FIG. 1, the actuating means 14 furthermore comprise a push button 16, which is mounted to the operating block 15. However, instead of a push button 16 also an activating lever may be provided.

[0042] For controlling the operation of the slider 10, the operating block 15 is connected or coupled to the slider 10, so that the operating block 15 and the slider 10 synchronously move. For controlling the operation of the flap 11, the operation block 15 comprises a recess 17 interworking respectively cooperating with the flap 11. In this way, the actuating means 14 are mechanically coupled to the slider 10 and the flap 11.

[0043] Furthermore, the dosing section 4 comprises an optional lock 18 pivotally mounted in the push button 16 by means of a second pivot 19. Finally, the dosing section 4 comprises optional bumps 20 arranged in the upper wall of the third tubular body 9 and a shocking lever 21, which is part of the operating block 15 in this case.

[0044] Next, the operation of the combined storage, dosing and mixing device 1 is described by reference to FIGS. 1 and 2.

[0045] FIG. 1 shows the device 1 in a first state, in which the slider 10 is open while the flap 11 is closed. FIG. 2 shows the device in a second state, in which the slider 10 is closed while the flap 11 is open. The transition from the first state into the second state works as follows:

[0046] When the actuating means 14 are actuated and the operation block 15 is moved from the left to the right, the slider 10 is synchronously moved with the operation block 15 and continuously closes the upper aperture in the upper wall of the third tubular body 9. At the same time the recess 17 moves from the left to the right and at some point in time releases the flap 11 so that it swivels down driven by the gravity force. Meanwhile the upper aperture in the upper wall of the third tubular body 9 is fully closed by the slider 10. In this way, the actuating means 14 respectively the operation block 15 control the movement of the slider 10 and the flap 11 so that either the device 1 is in its first state or in its second state, and either the first container space A is connected to the dosing space C through the upper aperture, or the second container space B is connected to the dosing space C through the lower aperture. Accordingly, the dosing section 4 performs the function of a lock.

[0047] Apart from the first state and the second state, the device 1 upon movement of the operation block 15 passes a third state, in which both the slider 10 and the flap 11 are closed. In this third state, the slider 10 has already closed the upper aperture, but the flap 11 is not yet released and still closes the lower aperture.

[0048] By means of the optional lock 18 the actuating means 14, in particular the operating block 15, can be held in the first state. For this reason, the lock 18 may be swiveled to the right, so that it hinders the movement of the actuating means 14. The optional lock 18 may also be designed to hold the actuating means 14/the operating block 15 in the third state in an alternative embodiment.

[0049] The device 1 may also comprise an optional spring (not shown in the Figs.) keeping the actuating means 14 respectively the slider 10 and the flap 11 in the first state or the third state when idled, i.e. when the push button 16 is not pressed.

[0050] The combination of the upper slider 10 and the lower flap 11 offers several advantages. First, the movement of the slider 10 cannot be hindered by the content in the first container space A (e.g. powder and/or crumbs), even if the content is agglomerated or clumped. Prior art designs having a flap instead of a slider 10 suffer from the weight and the resistance of the content in the first container space A acting against an upward movement of an upper flap, particularly when said content is agglomerated or clumped. In this case, opening the flap may get an impossible task and impatient users induce high forces onto the device 1 what may cause breakdown of fragile parts. Basically the same counts for an upper flap moving downward. While the flap may swivel down into the empty dosing space C, it cannot move upwards when the content in the first compartment A gets into the dosing space C. Even if the flap moves upwards, the dosing is compromised with high probability.

[0051] On the other hand, a flap 11 is beneficially for closing the lower aperture of the dosing section 4. In the example shown in the FIG. 1, the flap 11 just opens towards the second container space B of the second compartment 3 and stays out of the dosing space C, i.e. it swivels downwards. In this way, dosing is not compromised, and the flap 11 easily opens. In this example, basically no user force is necessary as the flap 11 opens by the force of gravity, because it is heavier on the side of the pivot 12, which faces the dosing space C than on the side facing the recess 17.

[0052] The design of the dosing section 4 offers even one more advantages. According to the mechanism, the flap 11 just opens in the upright position of the device 1 when the first compartment 2 is positioned over the second compartment 3 and is kept close in the upside-down position of the device 1 when the first compartment 2 is positioned below the second compartment 2, even if the actuating means 14 are activated.

[0053] This is achieved by means of the automatic gravity opening of the flap 11 combined with the special cooperation with the recess 17. The recess 17 in the right position enables the flap to swivel down but it does not force it. So the flap 11 just opens in the upright position of the device 1, but stays closed in the upside-down position. In this way, the liquid in the lower, second container space B is hindered to flow into the dosing space C or even into the upper, first container space A what would possibly spoil the content of the first container space A, which usually shall be kept dry. If such a contamination stays undetected for a longer time, even substances injurious to health may evolve.

[0054] The flap mechanism is also useful when shaking the device 1, as the liquid in the lower, second container space B sloshing against the flap 11 even increases the closing force acting on the flap 11 and thus its seal effect. This is another reason that the content in the first container space A stays dry under any condition.

[0055] Another optional but yet useful feature is the shocking lever 21, which is mechanically coupled to the actuating means 14 or even part of the same like it is the case in the Figs. By a movement of the operating block 15, the shocking lever 21 moves over the bumps 20, when the actuating means 14 are activated and knocks against the upper wall of the dosing section 4 when it has passed a bump 20 and is released. In this way, the content in the upper, first container space A is loosened and agglomerations and clumps are released. Hence, the dosing operation is eased. In the example shown in the Figs. there are two bumps 20. However, any other count of bumps 20 is applicable, and instead of bumps 20 also ramps or other elevations (or indentations) may be used.

[0056] For basically the same reason, the device 1 may comprise an optional scratcher 22, which is part of a slider 10a or connected thereto and which protrudes into the first container space A, as this is shown in FIG. 3. In this way, a movement of the slider 10a causes a movement of the scratcher 22, which in turn scratches the bottom side of the content in the container space A. Accordingly, said content is loosened and agglomerations and clumps are released. Thus, the rake-like scratcher 22 is particularly useful to loosen solidified hygroscopic powders.

[0057] Concretely, FIG. 3 shows a base body 23 of the slider 10a with an opening 24 and the scratcher 22 fixedly connected to the base body 23. Additionally, FIG. 4 shows a detailed cross sectional view of the slider 10a in the third tubular body 9 in its open position, FIG. 5 in the closed position.

[0058] In FIG. 3, the scratcher 22 is designed to move, particularly swivel, between a scratching position, in which it protrudes into the first container space A, and an idle position, in which it is arranged in the plane of a base body 23 of the slider 10a. FIG. 3, which corresponds to an open position of the slider 10a (like this is shown in FIG. 1 and FIG. 4), shows the scratcher 22 swiveled upwards into the first container space A. In the closed position of the slider 10a (like this is shown in FIG. 2 and FIG. 5), the scratcher 22 swivels into its idle position, in which it is arranged in the plane of the base body 23.

[0059] While the embodiment shown in FIG. 3 is advantageous, other embodiments are possible as well. For example, the scratcher may have fixed protrusions, which move within the first container space A respectively in grooves in the third tubular body 9. The shape of the protrusions may also be different to the one shown in FIG. 3. For example, the scratcher 22 may have triangular teeth.

[0060] In FIG. 3 the connection between the scratcher 22 and the base body 23 simultaneously performs the function of a hinge and a spring, which forces the scratcher 22 upwards. Although this is an advantageous embodiment, there may also be a separate hinge and a separate spring.

[0061] All in all, the combined storage, dosing and mixing device 1 is very user friendly, and it is almost impossible to use it in the wrong way. It just can be used in the intended upright position, and by activating the lock 18 it cannot be actuated unintended, for example when the device 1 is transported in a bag. In addition, the shocking mechanism supports the dosing process.

[0062] By provision of a first compartment 2 of appropriate size, many dosing sequences can be performed and by changing the liquid in the second compartment 3 many servings may be prepared. In this context, one should note that also more than one doses may be mixed with one portion of liquid. Thus, the end product may be varied and adapted to personal preferences with high accuracy and repeatability.

[0063] The combined storage, dosing and mixing device 1 may be generally used for any mixing task. Particularly, it is useful for baby formula, mixing protein shakes or milk shakes, preparing cereals, etc. Accordingly, the first container space A may be filled with powder or crumbs or a mixture of both, and the second container space B may be filled with water, milk or any other liquid (cold or hot). Even the preparation of Vinaigrette is possible, if herbs are filled into the first container space A and vinegar and oil is filled into the second container space B. Also technical applications are imaginable, for example mixing paints, glue, putty and the like.

[0064] It is noted that the invention is not limited to the embodiments disclosed hereinbefore, but combinations of the different variants are possible. In reality, the combined storage, dosing and mixing device 1 may have more or less parts than shown in the Figures. The combined storage, dosing and mixing device 1 and parts thereof may also be shown in different scales and may be bigger or smaller than depicted. Finally, the description may comprise subject matter of further independent inventions.
