Description

Technical area

The present invention relates to a metering system and a method for metering a substance present in a container.

State of the art

A variety of metering systems are known from the prior art, which allow to separate a certain amount of a liquid or free-flowing substance from a container present in a larger amount of material and then deliver it to the outside. Such metering systems generally have two chambers or containers which are interconnected via a feed opening. The metering takes place by transferring a certain amount of the substance from the first (larger) container, which serves as a reservoir for the substance to be metered, via the feed opening into the second (smaller) container, wherein the amount of material transferred is usually through the Form or the volume of the second container is predetermined. Subsequently, this defined amount of substance can be removed from the second container, wherein the removal is normally carried out by pouring or pouring. When pouring it should be prevented that further material from the first container nachfliesst in the second container and is discharged to the outside. Essentially, two variants of metering systems can be distinguished, which solve the problem of recharging with different agents.

In a first variant, the feed opening is provided with a closure which can be closed before pouring to prevent overflow from or backflow into the first container (cf., for example, DE 3 527 124 A1, DE 3 801 DE 10 2009 018 349 A1, DE 10 2009 043 193 A1, DE 20 2008 000 028 U1, EP 1 870 682 A1, WO 2011/085 068 A2). This first variant is implemented in the known from the prior art solutions usually in the form of a complex, multi-part mechanism.

In a second variant, a Nachfliessen is thereby prevented that the flow path from the first container to the pouring in the second container comprises a section which lies in the pouring position of the metering above the level in the metering (see, eg, DE 1 088 418, DE 3,120,234 A1, DE 10 103 477 A1, EP 1 041 368 A1, EP 2008 940 A2, EP 2 492 210 A1, US Pat. No. 1,498,491, US Pat. No. 2,233,996, WO 2004/017 028 A1, US Pat. No. 5,029,736). The said section may correspond to the loading opening. In dosing systems for powdered substances but can also be provided that the second container is divided by a guide member into two chambers in the Ausgiessstellung the Dosiersytems then a flow into the one chamber of the second container is possible, but no transfer to the other chamber, which is in communication with the pouring spout. The dosing system must be held in a specific orientation. Furthermore, the implementation is usually constructive demanding and therefore not sufficiently inexpensive to realize.

In both variants, the first and the second container are usually formed as a unit. This limits the dosing systems in their application. From DE 3,801,286 A1 and US 5,029,736 further metering systems are known, in which the first container has a neck into which the second container is inserted. As the first container thus a conventional bottle can be used, which is simple and inexpensive to manufacture. Furthermore, first and second containers can be manufactured separately and flexibly combined. In US 5,029,736, the loading port closure actuating mechanism occupies a majority of the top of the second container.

In the device shown in DE 3 801 286 A1, the top of the second container is blocked by the attachment of the necessary guide member. Further, the second container is divided into two chambers, one of which must be closed when pouring. As a result, the size of the pouring opening can be limited. However, a large pouring opening may have certain advantages. For example, it allows you to remove the transferred into the second container amount of substance with a spoon or other tool.

Object of the invention

It is an object of the present invention to provide a metering system which is inexpensive to manufacture for mass products, especially for their single use, and flexible in use. Further advantages and objects of the present invention will become apparent from the following description.

Presentation of the invention

The above object is achieved according to the invention by a metering system according to claim 1. In particular, this involves a metering system, preferably a metering device, comprising: a first container having an opening and a neck adjoining the opening for storing a substance, an insertable into the opening of the first container second container having a side wall, a bottom, a substantially opposite the bottom of the arranged pouring spout and a feed opening, wherein the opening of the first container is closed by the second container, and a first closure for repeatably closing the pouring opening, wherein preferably: a second closure for closing the feed opening is provided, wherein the second closure is actuated by means of the first closure.

Under a usable in the opening of the first container second container should preferably be understood both a usable in the opening of the first container second container and a second container inserted into the opening of the first container.

According to a further embodiment of the invention, the pouring opening of the second container occupies at least half of the opening of the first container.

Further embodiments are described below, wherein the features mentioned in this context (individually) are to be regarded as preferred features and separately (as part of any dosing) or - unless they exclude - can be implemented in any combination.

The area (or cross-section) of the spout of the second container preferably corresponds to at least 50, 70, 80 or 90 percent of the area (or cross-section) of the opening of the first container. It could also be said that the pouring opening occupies a corresponding percentage of the opening of the first container.

A preferred size of the area (or cross section) of the opening of the first container is at least 5.10 or 15 square centimeters and / or at most 30 or 25 square centimeters.

Preferably, the second container fills the opening of the first container (substantially) and / or closes it. Preferably, the opening is round or oval. In this way, it can be avoided that substance empties out of the first container past the second container when emptying the substance located in the second container.

Since only a subset of the substance stored in the first container reaches the second container, the first closure is designed such that it can be opened and closed at least twice. This can be done by, for example, unscrewing or clipping the first closure from the first container or even opening a part of this first closure to remove the substance provided in the second container and closing it after removal. As a rule, the first closure is designed such that several times a subset of the substance stored in the first container can be removed from the second container.

The feed opening may be arranged in the side wall or in the bottom of the second container, wherein the feed opening is preferably arranged in the side wall. By arranging the feed opening in the side wall, a simpler filling of the second container may be possible than if the feed opening is arranged in the bottom.

The neck of the first container may have a cross section which is smaller, larger than or equal to a cross section of a subsequent to the neck container body of the first container, wherein the stored substance is usually located in this container body. As a rule, the neck has on its outer side fastening elements on which the first closure can be fixed. The neck in the sense of this application is formed for receiving the second container.

According to a further embodiment of the invention, the side wall of the second container is at least partially against an inner side of the neck. Here, the side wall may be configured such that the second container is centered relative to the first container when the second container is inserted into the first container. For centering, the side wall, for example, along a longitudinal direction of the second container extending ribs or projections have, which bear against the inside. In this case, the substance can pass from the first container past the ribs or projections to the at least one feed opening in the side wall. Also, the side wall may abut circumferentially on the inside and prevent the substance stored in the first container from reaching the closure during filling of the second container. Also, the side wall may have an interference fit in connection with the inside of the neck, so that the second container inserted into the first container can be removed from the first container only with great effort, possibly not destructive.

According to a further embodiment of the invention, the first container first attachment means and the second container with the first attachment means corresponding second attachment means, wherein the first attachment means and the second attachment means cooperate such that the first container and the second container connected to each other captive are. Conveniently, the second container is inserted or used in the first container and / or designed removable from the first container. For this purpose, it may be advantageous if the maximum extent of the second container at right angles to its (extending from the bottom to the pouring) longitudinal axis is less than the maximum extent of the opening of the first container. An exception may be the edge of the pouring opening, which preferably has a greater maximum extent (i.e., protrudes laterally beyond the opening of the first container) to prevent the second container from slipping into the first container.

As an alternative to a removable second container may also be provided that the second container is firmly connected after insertion with the first container.

Both variants have their advantages. A removable second container can simplify handling. Firmly connected containers improve, among other things, the tightness. Furthermore, the fastening means may be designed such that the second container is permanently connected to the first container. The attachment means may also be configured such that the second container is movable relative to the first container such as, for example, possibly rotatable within a predetermined angular range.

In one embodiment, the second container is cup-shaped and / or the pouring is limited (on one side or around) by the side wall or extends to the side wall. This facilitates the emptying of the second container, since the angle of inclination, at which the pouring opening is located at the lowest point of the second container, is comparatively small. Depending on the configuration of the second container, a complete emptying of the second container can thus already take place in the horizontal position.

Conveniently, the first and the second container (in particular the inside of the first container and the outside of the second container) sealingly cooperate, so that the passage of material between the first and second container is prevented. Alternatively or additionally, the second container is preferably located on the inside of the neck of the first container and / or on the edge of the opening of the first container, and preferably along the entire circumference of the second container. Particularly preferably, the edge of the pouring opening of the second container is in contact with the edge of the opening of the first container or the former rests on the latter.

The flow path from the interior of the first container to the pouring opening in the second container may comprise a portion which lies in the pouring position of the metering above the filling level or the substance surface in the first and / or second container. The portion is preferably between the interior of the first container and the entrance to the second container. Alternatively or additionally, it can be provided that the one or more (in particular all) feed openings are arranged in this section. As a result, a transfer of material from one to the other container during pouring is prevented.

As already described in connection with the prior art, a preferred orientation can also exist in the dispensing position metering system according to the invention, e.g. if only one feed opening is provided. In this context, it may be advantageous if the first container has a handle (in particular a handle) and / or if it is not radially symmetrical with respect to its outside (or at least twice in maximum rotational symmetry, for example oval in cross-section). This results in a preferred grip and holding direction for the user.

Alternatively, however, it can also be provided that the dispensing system can be kept in each rotational position with respect to a (extending from the bottom to the opening of the first container) longitudinal axis of the dosing system. In this context, it may be advantageous if the first container or at least its neck (in each case inside and / or outside) and / or if the second container (inside and / or outside) are formed substantially radially symmetrical (preferably, they are exactly or at least 2,3,4,5 or 6-fold rotationally symmetric).

According to a further embodiment, the second closure for closing the feed opening and the first closure for closing the pouring opening are coupled. Preferably, the second closure is designed to be actuatable via the first closure. The second closure is preferably designed to be open and / or closable via the first closure. Conveniently, closure of the first closure causes opening of the second closure and / or opening of the first closure effects closure of the second closure. As a result, when the first container and the second container are closed by the first closure, substance can pass from the first container into the second container through the opened feed opening.

In a particularly preferred embodiment variant is provided that the first closure cooperates with the first container and / or is connectable. Preferably, the first closure is capable of closing not only the pouring opening of the second container (when inserted into the first container), but also the opening of the first container, preferably even when no second container is present.

The first closure is advantageously a lid with a screw cap, in particular with a screw cap. Conveniently, the neck of the first container has an external thread, which is designed to cooperate with an internal thread of the lid.

The second closure may be arranged on the first or on the second container. Preferably, the second closure is formed as part of the second container. If the second container is removable from the first container, it is advantageous if the loading opening can remain closed even after removal by the second closure.

According to a further embodiment, the second closure is designed as a flap. As a result of the closure displaced into a first position, the flap, which is pivotably connected to the second container in an edge region of the pouring opening, is pivoted in such a way that material can be displaced from the first container into the second container and vice versa through the loading opening. The flap has a contact point for contact with the first closure. The flap can hereby be connected to the first or second container at or in the region of the edge of the pouring opening (preferably movably). The dosing system can then be designed, for example, such that the closure can press against the point of contact, which may be formed as a projection, for example, as a result of which the flap can be displaced in the direction of the neck of the first container or away from the neck. The flap may preferably be arranged in a channel which extends from the pouring opening in the direction of the bottom of the second container. The channel may extend to the bottom of the second container.

Regardless of the type or the presence of a second closure, it may be advantageous if the side wall of the second container has one or more extending in the longitudinal direction of the second container channels. These may extend to the bottom and / or to the pouring opening. If the channels (in the second container inserted into the first container) extend into the region of the neck of the first container, then they are preferably separated from one another by regions of the side wall which extend to the inside of the neck of the first container.

A further embodiment provides that the second closure is designed as a slide, wherein a relative movement between the slide and the loading opening is made possible, through which the slide and the loading opening can be made to coincide. The relative movement is effected by a driver coupled to either the second container or the slider which is adapted to be carried along by the first closure. The driver may be coupled or connected to the slider or to a portion of the second container in which the loading aperture is disposed so that movement of the driver causes movement of the slider or the loading aperture. If a plurality of charging openings are provided, then a plurality of slides may also be present, which are preferably connected to one another and / or jointly movable.

Furthermore, it can be provided that the second container and / or the slide are designed to be rotatable relative to the first container. Alternatively, the second container and / or the slider may be rotationally fixed relative to the first container. If the second closure is a slide, then for closing and opening the feed opening either the second container, on which the feed opening is arranged, or the slide can be rotated relative to the first container, wherein the axis of rotation may correspond to the longitudinal axis of the metering system. It can also be provided that the slider is firmly connected to the first container or part thereof. Especially in this embodiment, to close the feed opening, it may only be necessary to rotate the second container at a predetermined angle relative to the first container.

Through the open feed opening a limited by the first container interior is connected to a limited by the second container interior. The charging opening is preferably smaller than the pouring opening.

The charging opening is conveniently arranged in the side wall of the second container.

Preferably, more than one, namely 2, 3,4,5, 6 or more feed openings are provided. One or more of the features mentioned in connection with the feed openings (e.g., channels, fins, second closure, etc.) may be present in a number corresponding to the number of feed openings.

The feed openings are conveniently arranged in the (preferably regular) distance from one another along the circumference of the second container and / or on different (in particular opposite) sides of the second container. This can be the case in particular if the second container has a substantially angular shape when seen in cross-section, whereby two parts of the container which are substantially opposite each other with respect to the longitudinal or central axis of the second container also in connection with substantially circular cylindrical containers Sidewall to be considered as opposite sides of the second container. These configurations may cause the dosing system to be held and used in various orientations.

If a plurality of charging openings are provided, their margins lying closest to the bottom of the second container can be arranged substantially the same distance from the bottom of the second container and / or from the pouring opening.

Furthermore, it is preferred if an edge of the feed opening is arranged between one of the opening facing away from the opening and an end of the neck of the first container. In this way, the feed opening can be arranged such that it does not lie further in the container interior of the first container than the container interior facing the end of the neck of the first container. Advantageously, the feed opening in an upside-down metering - in this case, the pouring opening in the direction of earth gravitational force - be located where an inner wall of the first container and the side wall of the second container meet. As a result, dead spaces in the upside-down dosing be avoided, ie in the direction of the pouring, in which otherwise could collect a portion of the stored substance, whereby this part could not be fed through the feed opening to the second container. By avoiding such dead spaces, an improved emptying of residues can be achieved.

Unless otherwise stated, the information given in this document refer to the state of the metering system in which the second container is disposed in the opening of the first container or inserted into this.

According to a further embodiment, the feed opening is arranged in a direction extending from the bottom of the second container to the pouring out channel. The channel is preferably provided in the side wall of the second container. Preferably, the feed opening is arranged at the (or in the region of) the pouring opening closer end of the channel. The channel may advantageously extend to the bottom and / or to the edge of the pouring opening of the second container.

According to a further embodiment of the invention, a first volume, which is bounded by the bottom and a first portion of the side wall is 0.7 to 1.3 times as large as a second volume, which faces through a second container Inside the first closure and a second portion of the side wall is limited. The first portion extends from the bottom of the second container to a bottom nearest the bottom of the feed opening and the second portion extends to the first portion thereafter to the inside of the first closure. The second volume is preferably a volume that can be substantially filled by turning the dosing system upside down, i.e., by turning the dosing system upside down. with the pouring down, ie in the direction of the gravitational force earth, is oriented. Should a plurality of charging openings be provided, then the indications in each case relate to the closer charging opening, i. the one that is closer to the ground or closer to the first closure.

Depending on how the metering system is configured, it may be advantageous if the first volume (e.g., at least 5.10 or 20 percent) is greater than the second volume. In this way, when reversion of the metering system, ie when the pouring opening facing upwards, that is, against the gravitational gravitational force, does not reach or fall to the feed opening on the bottom of the second container, which results in particular in the use of powdery or free-flowing Material jamming of the second closure is prevented.

According to a further embodiment, an outer side of the bottom of the second container (or at least the outside thereof) is deformed outwardly. The deformation can be configured two-dimensionally or three-dimensionally. In the case of three-dimensional deformation, the floor can be designed, for example, spherical, pyramidal or conical. Also, the top of the pyramid or the cone may be rounded spherical. The bottom of the second container may be formed such that its outer side opposite the inside is flat. In this way it can be prevented that material remains lying on the outside of the floor, whereby a residual emptying of the dosing system can be improved.

[0046] According to a preferred embodiment, the first container and / or the dosing system is a head-up bottle.

It can also be provided that the bottom of the first container is deformed outwards. The deformation can be configured two-dimensionally or three-dimensionally. In the two-dimensional deformation, the bottom may be formed as a curved surface. For example, in the case of three-dimensional deformation, the bottom may be spherical. Also, the bottom may be configured pyramidal or conical. Furthermore, the tip of the pyramid or cone may be spherically rounded. The bottom of the second container may be formed such that its outer side opposite the inside is flat. This stops the user from turning the first container upside down, i. with the (by the first closure closed) pouring down, ie in the direction of the gravitational force earth, oriented, turn off. This causes matter to pass from the first container through the open feed opening into the second container and the second container is filled in the next use by the gravitational force of gravity.

According to a variant embodiment, it may be provided that the outside of the bottom of the first container substantially opposite the opening does not form a footprint which allows a stable equilibrium position of the first container. This means that the first container is not in a stable equilibrium position when it is placed on this footprint or easily falls over.

According to a further embodiment of the invention, the second container is integrally formed. The second container may be made of plastic. If the second closure is designed as a pivotable flap, the joint required for this purpose can be integrally formed in the container, for example as a film hinge. Also, the second container may be formed as a plastic injection molded part, in which case all sprayable plastics can be used. The first container may also be made of plastic. The first container may be formed as a plastic injection molded part or manufactured by stretch blow molding or extrusion blow molding.

It is preferred if at least two adjacent feed openings are provided, wherein they are preferably arranged in the side wall of the second container.

The terms "substance", "substance" and "material" are used interchangeably and designate the metered, preferably liquid or free-flowing matter.

According to another embodiment of the invention, a method of dosing a substance by means of a dosing system as described in this document is provided. The dosing system points a first container for storing a substance having an opening and a neck adjoining the opening, a second container for receiving a portion of the stocked fabric having a side wall, a bottom, a bottom substantially oppositely disposed pouring spout and a preferably arranged in a side wall feed opening, wherein the opening of the first container is closed by the second container. a first closure for repeatably closing the pouring spout. The method comprises the following steps: Transferring the metering system to a first position wherein the pouring opening is substantially in the direction of gravity, the pouring opening being closed by the first closure, a certain amount of material present in the first container being gravity fed via the feed opening enters the second container and the inside of the first closure, Transferring the metering system into a second position, in which the pouring opening points substantially counter to the direction of the gravitational force of the earth, wherein the quantity of the substance located in the second container reaches the bottom of the second container through the gravitational force of the earth, Opening the pouring opening by opening the first closure or a part thereof, wherein by opening the first closure or a part thereof, the feed opening is closed by the second closure which can be actuated by means of the first closure, and Removing the amount of the substance or a part thereof present in the second container. This can be done by pouring or pouring or by means of a tool (for example a spoon).

According to a preferred embodiment, said use or method as steps includes one or more actions described in terms of the suitability, capabilities or characteristics of the dosing system or portions thereof.

Embodiment of the invention

The invention will be explained by way of example with reference to the drawings. FIGS. 1a to 1f and 2a to 2f show a first and a second variant of a metering system 11 or its components.

Fig. 1a - 1f represent said first variant of a metering system 11, comprising a first container 21 and a second container 41. The first container 21 is here a bottle with a neck 23. The neck 23 is over a shoulder 29 connected to a container body 27 of the bottle. The second container 41 is substantially cup-shaped and has a side wall 53, a bottom 51 fixedly connected to the side wall 53, and a pouring opening 45 arranged substantially opposite the bottom 51. The second container 41 is inserted into the neck 23 of the first container 21. It may be removable or firmly attached to the first container 21 after insertion, respectively. The removability can facilitate handling. On the one hand, a subsequent flow of material from the first container 21 can be avoided. On the other hand, emptying is simplified in certain situations. In addition, a refillability of the first container 21 can be effected by removing the second container 41. A firm connection of the second container 41 with the first container 21, however, may have a positive effect on the tightness. In the dosing system 11 shown, the second container 41 is removable and has an edge 49 which rests in the inserted state of the second container 41 on the edge of the opening 25 of the first container 21 and so slipping in of the second container 41 in the first container 21st prevented. The side wall 53 of the second container 41 rests in this embodiment along its entire circumference on an inner side of the neck 23, so that no material between the neck 23 and the side wall 53 can pass. The side wall 53 has on the side of the pouring opening 45 in an area an outer contour or an outer cross section, which substantially corresponds to the inner contour or the inner cross section of the neck 23. In the present example, the said region comprises both the edge 49 of the pouring spout 45 and that part of the side wall 53 which adjoins the edge 49, to a length substantially equal to the length of the neck 23, but also shorter can. At least one feed opening 55 is arranged in the side wall 53. In the present embodiment, four mounting holes 55 are provided which are made the same. Each adjacent mounting holes 55 each include an angle of 90 °. The feed openings 55 are arranged at the transition between neck 23 and shoulder 29 or neck 23 and body 27 of the first container 21. To install the feed opening 55 between the pouring spout 45 and said transition may have the advantage of ensuring reliable residue discharge. The emptying can be further improved by a spherical shape here of an outer side of the bottom 51 of the second container 41. This can be counteracted a lingering of material and this material are supplied to the second container 41. Also, the presence of a plurality of feed openings 55, which are arranged on different (preferably opposite) sides of the second container 41, serves inter alia this purpose. A further advantage of several feed openings 55 is that the metering system 11 does not have to be held in a specific orientation during handling. An inner wall of the body 27 of the first container 21 is spaced from the side wall 53 of the second container 41 so that the material to be dispensed between the said inner wall and the side wall 53 to the feed openings 55 can flow. In the present example 55 leading channels 59 are provided in the side wall 53 to the feed openings, which additionally increase the said distance. In addition, it is advantageous (irrespective of the other configuration of the dosing system) if an angle enclosed between the neck 23 and the shoulder 29 (or body 27) of the first container 21 is greater than 90 degrees and in particular greater than 95.100 or 105 degrees. or when the shoulder 29 from the neck 23 to the bottom of the first container 21 is sloping down (at least on the inside). Thus, the material to be metered flows or slips when the metering system 11 is upside down and thus in the direction of a gravitational force of gravity, more easily in the direction of the feed openings 55 due to the gravitational force of the earth. The pouring opening 45 can be closed by a first closure 47, which is designed as a screw cap in the present exemplary embodiment. At the neck 23, a thread 31 (external thread) is mounted, which is intended to cooperate with the internal thread of the removable cover 47, which closes the pouring opening 45. The feed openings 55 on the second container 41 can be closed by a second closure 57 in the form of a flap 71. The flap 71 is fastened on or in the region of an edge 49 of the pouring opening 45 on the second container 41. Preferably, container 41 and flap 71 are integrally formed, e.g. made of plastic. The flaps 71 may additionally be biased in the closing direction, in order to achieve improved tightness of the second closure 57.71. The connection 75 between flap 71 and edge 49 is reversibly elastic and has a projection 73 which projects beyond the edge 49 and extends in the direction of the first closure or cover 47. The first closure 47 is designed to contact the edge 49 in the closed state of the pouring opening 45. Since the projection 73 rises above the edge 49, it first comes into contact with the first closure 47 when the pouring opening 45 closes, before the closure 47 completely closes the pouring opening 45. The flap 71 is arranged in the closed state at a distance from the inside of the neck 23. The pressure exerted by the cover on the projection 73 leads to a reversibly elastic bending of the flexible connection 75, whereby the flap 71 is pressed in the direction of the neck 23. Instead of the projection 73, the connection 75 can also rise over the edge 49 itself. It could also be said that the flap 71 is substantially L-shaped and is movably attached to the second container 41 with the short leg of the L. Pressure on the short leg causes it to pivot in the direction of the bottom 51 and the long leg is pivoted transversely thereto in the direction of the neck 23. FIGS. 1a-b show the flap 71 in the opened state, while FIGS. 1c-f show a closed flap 71. The edge 49 of the pouring opening 45 is in this example along the entire circumference of the pouring opening 45 on the neck 23 at or on the edge of the opening 25. The side wall 53 also abuts the inside of the neck 23 of the first container 21, namely at least two, three or four points distributed along the circumference of the side wall 53. It is advantageous if these locations (with respect to their distance from each other) are distributed substantially uniformly along the circumference. Thus, the second container 41 stably seats in the neck 23 of the first container 21. The locations where the side wall 53 abuts against the inside of the neck 23 are separated by locations where this is not the case. Expediently, these are channels 59 extending from the bottom 51 in the direction of the pouring opening 45. In the example shown, the flaps 71 are arranged in these channels 59. As a result, with the flaps open, hardly any material can flow past the flaps 71 laterally. Again, four feed ports 55 are provided, but another number (e.g., 1 to 20 or 2 to 10 pieces) is also possible. A first volume to be dispensed, which is a part of a substance stored in the first container 21, is defined by the bottom 51 and a first portion of the side wall 53. Said first portion extends from the bottom 51 to a bottom 51 next to the arranged edge 58 of the feed opening 55. A second volume is bounded by an inside of the shutter 47 and a second portion of the side wall 53, wherein the second portion seamlessly to the first subsection connects. The first volume is 0.7 to 1.3 times the size of the second volume.

2a-f show a second variant of a metering system 11 which, with the exception of the design of the feed openings 55 and the second closure 57 closing them, is essentially identical to the first variant mentioned above. Shown is only the second container 41, to which the changes refer. The second closure 57 for closing the feed openings 55 has a number of feed openings 55 corresponding number of slide 81, which are designed to be displaceable relative to the feed openings 55. The sliders 81 are connected to each other by a bottom part 83 and so are movable together. The feed openings 55 are arranged as in the previous variants longitudinally oriented channels 59, wherein the channels 59 are designed wider, so that in the open state of the feed opening 55 laterally the feed opening 55 space for the slide 81 remains. The bottom part 83 is rotatable relative to the second container 41, wherein a rotation axis corresponds to a longitudinal axis of the second container 41. The design possibilities of such a second closure 57 in the form of a slide 81, however, are manifold. Thus, it is also conceivable not to arrange the slider 81 outside of the second container 41 but inside. For example, the slider (or a plurality of slides) may be secured to a ring or to a hollow cylinder which bears against the inside of the side wall 53 and is rotatable relative thereto. The ring or the hollow cylinder then acts as a driver, which are adapted to be taken from the first closure and thereby rotated relative to the side wall 53, whereby an opening and closing of the feed opening 55 is made possible. The ring or the hollow cylinder can, for example, in the region of the edge 49 of the pouring opening 49 with the first closure 47, e.g. the cover shown in Fig. 2a - b, directly (or indirectly via one or more extensions) in operative connection. Alternatively, the ring or hollow cylinder may also be fixed to the first closure, e.g. a lid to be connected.

Fig. 3 shows a method for dosing a substance by means of a dosing system 11 with a first container 21 for storing a substance having an opening 25 and a neck 23 adjoining the opening 25, a second container 41 for receiving a portion of the stockpiled material with a side wall 53, a bottom 51, a bottom 51 substantially oppositely arranged pouring opening 45 and a preferably arranged in the side wall 53 feed opening 55, wherein through the second container 41, the opening 25th the first container 21 is closed, and a first closure 47 for repeatably closing the pouring opening 45.

The method comprises the following steps: Transferring S1 of the dosing system 11 into a first position, in which the pouring opening 45 points substantially in the direction of an earth-gravitational force, wherein the pouring opening 45 is closed by the first closure 47, wherein a certain amount of a material present in the first container 21 through the Earth gravitational force passes via the feed opening 55 into the second container 41 and onto the inside of the first closure 47, Transfer S2 of the dosing system 11 in a second position in which the pouring opening 45 is substantially opposite to the direction of gravitational force, wherein the substance located in the second container 41 by the gravitational force of earth on the bottom 51 of the second container 41st arrives, Opening S3 of the pouring spout 45 by opening the first shutter 47 or a part thereof, whereby by opening the first shutter 47 or a part thereof the feed opening 55 is closed by the second shutter 57, 81, 81 actuable by the first shutter 47, and Take S4 of the present in the second container 41 amount of the substance or a part thereof.
