EP2911949B1 - Container and method for adding a mixture component - Google Patents

Description

Technical area

The invention relates to a container, in particular a cap for bottles, for receiving a mixing component and for their delivery into a second container. In addition, a method for adding a mixing component using such a container or article is the subject of the present invention.

State of the art

Various containers - usually in the form of attachments for bottles - are known from the prior art, which allow components of a mixture, such as a mixed drink, to be filled and stored separately and mixed together only when necessary. This is useful, for example, when the components react with one another or when the mixture has a lower durability than the individual components of which it is composed.

The WO 2006/122612 A1 describes an attachment for bottles for producing a mixed beverage, which has a housing with a pouring opening, which is designed to receive a mixing component. If necessary, the mixing component can be mixed with another (normally closed) orifice of a base liquid contained in a bottle. The housing is divided for this purpose by a bottom part in a receiving chamber and in a connecting piece for the connection to the bottle. The housing is equipped with a blow-up device, which is receivable in the connection piece and serves to open a provided with a predetermined breaking point portion of the bottom part.

From the US 2002/0066677 A1 a storage container is known which can be connected to a bottle in order to admit a substance present in the storage container. The device has a housing for receiving the substance and an openable seal, which is arranged in the housing. In addition, an impingement portion is provided which is positioned in the housing between the seal and the housing opening and adapted to be pressed by the seal in the connection of the storage container with the bottle of the bottle. The impulse has the shape of a point and penetrates the seal in the middle.

The in the US 6,293,395 B1 described variant has a plurality of containers, each filled with different substances and provided with lids. When connecting the container, the lids are pressed as a whole from the container openings and thus get inside the container.

One from the WO 2011/030173 A1 known container has a lower part with an openable bottom and an internal thread. In the container part axially movable, a cutting tool is arranged, which is in the region of its lower end with an external thread in engagement with the internal thread of the lower container part and thus moves in rotation in the direction of the openable bottom. The rotation of the cutting tool relative to the lower container part can be achieved by rotation of a central container part. For this purpose, projections are provided in the region of the upper end of the cutting tool, which are received in axial guides on the central container part. The middle container part is rotatably connected to the lower container part and closed at its upper end with an upper container part in the form of a lid.

Object of the invention

It is an object of the present invention to propose a container which allows reliable mixing of two components as well as simple and inexpensive to manufacture. 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 container according to claim 1 and its use according to claim 19. In particular, it is a container having a chamber with a bottom for receiving a mixing component and an adapter for fastening the chamber to a second container. The adapter is about a first Connecting means connected to the chamber and has a second connecting means for connection to the second container. In addition, the adapter forms a flow channel for the mixing component extending between the first and the second connection means. The adapter also has in the flow passage on a cutting element with a bottom of the chamber facing cutting edge for opening the bottom of the chamber. Preferably, the first connecting means allows rotation of the chamber relative to the cutting edge and conveniently also relative to the adapter, wherein the cutting edge is adapted to cut through the bottom of the chamber along its edge upon rotation of the chamber. The cut-through can be circular in this case. It is advantageous if the chamber and the adapter are permanently connected to each other.

Hereinafter, further embodiments will be described, wherein the features mentioned in this context (individually) are to be regarded as preferred features and separately (as part of any container) or - if they do not exclude - can be implemented in any combination.

The mixing component may be in solid (eg powdery), liquid or pasty form.
The first connecting means allows movement of the chamber in the direction of the second connecting means and / or on the adapter and / or (wholly or partly) into the adapter, wherein the cutting edge is preferably formed in the said movement of the chamber with the bottom to contact the chamber and to release it along a circle or arc and / or along its edge from the chamber. Conveniently, the chamber for this purpose is rotatable relative to the cutting edge and preferably also relative to the adapter. This rotation can be made possible with advantage by the first connecting means.

Preferably, the opening of the chamber bottom does not take place automatically when connecting the container to the second container, as is known from the prior art Technique is known. The opening of the chamber bottom is advantageously executable independently of a connection of the container with or to the second container and / or before or after such a connection.

According to a preferred embodiment, the cutting edge is designed to only partially release the bottom of the chamber from the chamber during rotation, in particular maximum rotation, of the chamber. In this way, the bottom or the part cut from the bottom remains connected to the chamber and can not fall into the adapter or the second container. For the stated purpose (or for other purposes, for example in the presence of several cutting edges), the rotation of the chamber relative to the cutting edge or relative to the adapter may be limited with respect to the maximum angle of rotation. This can be accomplished by a stop that defines the maximum angle of rotation.

The container may advantageously be characterized in that the rotation of the chamber relative to the adapter with respect to the maximum angle of rotation is limited to less than 360 degrees, preferably less than 350 degrees. However, the angle of rotation may also be limited to less than 180 or 170 degrees (e.g., if two blades are provided) or less than 120 or 110 degrees (e.g., if three blades are provided). Alternatively or additionally, the rotation of the chamber relative to the adapter with respect to the maximum angle of rotation may be limited by stops. Also alternatively or in addition to what has been described, the chamber and the adapter may be interconnected such that rotation of the chamber relative to the adapter to open the bottom of the chamber may be clockwise or counterclockwise.

Furthermore, it can be provided that the rotation of the chamber takes place positively guided relative to the adapter. Due to the positive guidance of the rotary manual movement, the chamber can advantageously be displaced in the translatory direction and / or the manual rotation of the chamber relative to the adapter can positively cause an approximation between the chamber and the cutting edge and thus an opening of the bottom.

According to a preferred embodiment variant, the chamber or at least its bottom end is completely or partially receivable in the adapter, in particular in the adapter screwed into it. For this purpose, it is advantageous if the outer cross section or outline of the chamber substantially corresponds to the inner cross section or outline of the adapter. The chamber preferably has an at least partially (substantially) cylindrical, in particular circular-cylindrical, outer (and preferably also inner) form, wherein the same applies to the inner (and preferably also outer) shape of the adapter. The inner and outer molds are essentially defined by the outside and the inside of the side walls of the chamber and the adapter. Preferably, the above applies at least to the two facing ends of the chamber or the adapter, in particular to a length which substantially corresponds to the distance of the cutting element from the edge of the opening on the side of the first connecting means, i. the chamber-side opening of the adapter.

Preferably, the maximum outer diameter of the chamber at the bottom end is smaller and at the end remote from the adapter greater than the maximum inner diameter of the adapter at the end facing the chamber. Conveniently, said diameter or the outer cross section of the chamber increases from the bottom end in the direction of the opposite end. The same preferably also applies to the maximum inner diameter of the chamber or the cross section of the cavity. As described above, the bottom end of the chamber is received in the adapter, which is why its outer cross section (substantially) corresponds to the inner cross section of the adapter on the chamber side facing.

The chamber is preferably widened in the area that is not received in the adapter. As a result, an increase in volume of the chamber is achieved without the size of the adapter must be adjusted or the length of the chamber increases too much.

When mentioning a diameter in addition to the diameter in addition, the corresponding dimensions should be disclosed at right angles to the axis of rotation or the longitudinal axis of the chamber or the adapter, because diameters are defined only for circular shapes. For example, in addition to the mentioned maximum inner or outer diameter (the chamber or the adapter), the maximum distance of the inner wall or outer wall from the longitudinal axis is disclosed.
When mentioning a cross section, on the one hand, the cross-sectional area and, on the other hand, the edge or outline of the cross-sectional area are disclosed.

It is advantageous if the chamber has on its outer side, in particular on its side wall, a projection. Conveniently, the maximum outer diameter of the chamber at the location of the projection is greater than the maximum inner diameter of the adapter or its opening on the chamber side facing. Alternatively, one could say that the projection protrudes beyond the edge of the adapter or extends beyond the edge of the aperture into which the chamber is received. Advantageously, between the projection and the edge of the adapter, a removable, in particular by hand spacers is provided, which prevents approach of the projection and the edge. In this way, a contact between the cutting edge and the part of the chamber bottom to be opened and thus an accidental release of the mixing component can be avoided. The spacer is preferably a guarantee strip, which is conveniently connected via predetermined breaking points to the chamber (in particular the projection) and / or the adapter (in particular the above-mentioned edge).

Alternatively or additionally, the container may also be characterized in that said projection surrounds the chamber along its circumference, the projection preferably forming a seal adapted to cooperate sealingly upon contact with said rim of the adapter.

According to a further preferred embodiment, the chamber has a seal between cutting element (in particular cutting edge) and chamber (in particular chamber floor). Preferably, the seal is formed by the contact of the cutting element (in particular the cutting edge) with the chamber (in particular the chamber bottom). Conveniently, the seal extends along the edge of the bottom, in particular along the inside of the side wall of the chamber. The seal is preferably designed to come into contact with the cutting element (in particular with the cutting edge) and cooperate sealingly therewith. Preferably, said contact takes place before or while the cutting edge comes into contact with the part to be cut (in particular a weakened region or a predetermined breaking point) of the soil. In this way, at the points where the chamber is opened, a seal is established before or during the opening. For this purpose, the seal may be located closer to the cutting edge than the part of the bottom to be cut. For example, the part of the floor to be cut can be arranged in a recess in the floor.

The above seals prevent passage of the mixing component between said parts, i. between the projection and adapter edge or between the cutting edge and the chamber. One or both seals are advantageously formed by a cylindrical surface or conical surface (preferably along the inside or the outside of the adapter and / or the chamber) or generally by a circumferential projection.

It is advantageous if the chamber and the adapter are permanently connected to each other. Preferably, the chamber (especially by hand) can not be separated from the adapter without violence and / or non-destructive. When the term "insoluble" is used, in addition to its usual meaning, alternatively or additionally, the meaning "undelayable" is disclosed. The permanent connection may be made by the first connection means or by another means.

According to a further embodiment, the container may be designed for a single use. There is a possibility that the container, if he once with the second container is connected, can remain connected to this until disposal. Preferably, the material or materials from which the first container is made may be recycled together with the material or materials from which the second container is made. Conveniently, both containers are made of plastic. Regardless, it is advantageous if the container has a fuse which prevents removal of the container from the second container. Also, the container after mounting to the second container inextricably linked to this, so that in accordance with a further embodiment of the invention, a completed container, preferably a plastic container, in particular consisting of a second container, the substance (preferably liquid) stored, the the mixing component is supplied, and a container storing the mixed component is formed.

The first connecting means, which serves to connect the chamber to the adapter, preferably has a first guide track and a sliding projection guided along (preferably in) the first guide track. At least one end of the first guideway is expediently designed as a stop for the sliding projection, so that the sliding projection can not leave the guideway. When rotation of the chamber relative to the adapter is provided, it is advantageous if the first guideway is (substantially) helical or helical in shape (with a substantially constant or varying pitch). The first guideway may (in particular by its length) additionally define the maximum angle of rotation. If, on the other hand, the chamber is linearly movable toward the cutting element, then also linear guideways are possible. Also conceivable are arcuate guideways or combinations of the aforementioned. For example, the first guide track could define a linear movement of the chamber in the direction of the cutting element by means of a linear section and allow the chamber to rotate relative to the adapter by means of an arcuate section adjoining it. Conveniently, one, two, three or more (first) guideways are provided, these preferably (essentially) in are arranged uniformly spaced from each other. The first guideway is preferably provided on the chamber, but may alternatively be arranged on the adapter. Pro guide track is conveniently a sliding projection available, which is arranged on the other of the relatively movable parts (chamber, adapter).

In the region of one or both ends of the first guideway, a step (or in general a resistor) may be provided. This step provides resistance to the movement of the sliding projection along the first guideway, or the step of overcoming it by the sliding protrusion requires an increased amount of force compared to the movement of the sliding protrusion along non-stepped portions of the first guideway. The step can be designed (only) in one or both directions of movement (non-destructive) surmountable. Between the step and the stop described above, or the end of the guideway, a pocket may be formed in which the sliding projection is reversibly or irreversibly fixed. In this way, the position of the chamber relative to the adapter can be reversibly or irreversibly fixed. Preferably, the sliding projection is reversibly fixed so that the sliding projection is removable from the pocket by moving toward the step, overcoming resistance. Preferably, the distance of the step from the end of the first guide track substantially corresponds to the extension of the sliding projection in the direction of movement.

According to an advantageous embodiment, a further, compared to the first guideway shorter (second) guideway is provided, wherein the second guideway and the first guideway in the region of their ends meet at a preferably acute angle. In the region of the other end of the second guide track, a step (or in general a resistor) is preferably provided, reference being made to the statements above with regard to its preferred embodiment. The second, shorter guideway preferably has the shape of a circular arc and extends at (substantially) constant distance from the chamber bottom. It allows, after opening the bottom of the chamber to rotate relative to the adapter in the opposite direction, so that the sliding projection from the first to the second guideway and finally reach their end, which form a stop and so a transmission of torque from the chamber to the Allow adapter. This may allow the removal of the adapter from the second container by means of a rotary motion.

The second container is preferably a container having an opening and a thread, in particular an external thread, wherein the thread is expediently arranged at the opening. Particularly preferably, the second container is a bottle. Accordingly, the second connecting means is preferably a thread, which is designed to cooperate with the thread of the container. However, the second connection means may also be a bayonet lock or another form-fitting connection.

The chamber and / or the adapter are advantageously produced by means of injection molding. Conveniently, the chamber and / or the adapter are made of plastic. Preferred materials are: HDPE, LDPE, PP, PET and mixtures or (if composed of several parts) combinations of said plastics, wherein the chamber and the adapter can be made of the same or different materials. By forming the adapter and the chamber in each case as a plastic injection molded part, large quantities can be manufactured inexpensively.

Furthermore, it is advantageous if the chamber has a pouring opening at its end opposite the base or facing away from the adapter. The opening is preferably closed and (preferably by hand) openable and / or resealable. The opening may for example be closed with a film or by means of a lid, which is connected, for example via a rotary closure with the chamber.

However, it can also be provided that the chamber (in particular at the above-mentioned point) has no openable pouring opening.
This depends on whether the container is intended to remain connected or removed after connection to the second container and addition of the mixing component. If a permanent connection is provided, then it is expedient if the container and / or the second container are provided with a Abschraubsicherung, which prevents removal of the container from the second container.

The cutting element and / or the cutting edge is preferably fixedly connected to the adapter in the rotational and / or translational direction or immovable relative thereto. Particularly preferably, the adapter and the cutting element and / or the adapter and the cutting edge are integrally formed. The cutting edge and the adapter can thereby be fixed relative to each other.

Furthermore, the cutting element has a preferably round or circular flow opening for the mixing component. The cutting edge is expediently arranged at the edge of the flow opening. More generally, the cutting edge (or blades) is preferably located on a circle whose center is defined by the axis of rotation (rotation of the chamber relative to the adapter). In this case, the cutting edge itself may be circular or circular-arc-shaped. In fact, in fact, the flow passage may have any shape, with an opening extending to the circle being preferred. Alternatively or additionally, the cutting element may have a circular projection or collar extending in the direction of the chamber, the cutting edge preferably being arranged thereon.

The cutting edge and / or the cutting element can be designed in such a way that the part of the base cut from the bottom is lifted by the cutting edge and / or the cutting element successively during the cutting or only after the cut and optionally fixed in a position that on the one hand the mixed component is preferably completely fed to the second container and on the other hand, the cut-off part of the bottom remains in the adapter, so it can not fall into the adapter and / or the second container. Also, the cut-off portion of the bottom may be fixed in an off-hook position after completion of the cutting operation. It should be noted that the mixing component is preferably supplied by gravity from the chamber to the second container, so that can be dispensed with additional tools for emptying the chamber.

Further, in the area where the blade touches the ground, or cuts the portion from the ground, the floor may be made thinner than the rest of the floor. This portion may be formed usually annular. By such a thinning, the translational force to be applied to the cutting edge can be reduced in relation to a force application on a non-thinned bottom.

It may also be provided more than one cutting edge or the cutting edge may have one or more tips. If multiple tips or multiple cutting edges are provided, it is preferred that at least two (not interrupted by another tip or cutting edge) exist between (one or two different) pairs of adjacent tips or blades that are different from each other. If, for example, only two cutting edges are present, then it is preferred if they are not arranged exactly opposite one another in relation to the throughflow opening. Now, if the maximum rotation angle of the chamber relative to the adapter (essentially) defined by the second largest of the distances or limits, so remains after the rotation of a connection between the floor and the chamber, whereby the floor fold away but can not fall off. More generally, the maximum angle of rotation should be less than the angle of rotation defined by the greatest distance. The distances define chords and circular arcs of the above circle whose center is defined by the axis of rotation (rotation of the chamber relative to the adapter) and whose radius is defined by the distance of the edges or points from the center. The circular chords or circular arcs (ie their lengths) define clearly an angle, among other things, the above-mentioned preferred maximum angle of rotation. The maximum angle of rotation can be predetermined, for example, by the stops in the guideways, between which the sliding projection guided is movable.

It is advantageous if the flow opening narrows in the direction of the second connection means and / or if the cutting element forms a funnel. Between the cutting element (in particular between the funnel) and the side wall of the adapter is preferably a (in particular annular) recess, wherein the recess or its opening preferably in the same direction as the opening of the adapter on the side of the second connecting means. The recess serves to receive the edge of the opening of the second container. Alternatively or additionally, it is preferred if the funnel is designed to project into the second container or its opening when the container is connected to the second container.

According to an advantageous embodiment variant can be provided that the chamber forms a cavity in which the cutting edge is arranged. The cavity may be a niche.
The details of this embodiment variant, unless otherwise stated, refer to the state of the container in which the cutting edge is in its initial position, ie the state of the container before the opening of the chamber bottom through the cutting edge.
The cavity may be formed, for example, by the bottom and / or by the side wall of the chamber.
Furthermore, it is advantageous if the cavity is open on one side and the cutting edge and / or the cutting element projects through this open side into the cavity. The open side is preferably the side facing the second connection means.
The cavity is advantageously opposite the inside of the chamber and / or separated from the mixing component by walls. These may be formed by the bottom and / or the side wall of the chamber.

• innerhalb der Seitenwand der Kammer oder innerhalb des durch die Seitenwand der Kammer definierten prismatischen Körpers (insbesondere Kreiszylinders) und/oder
• auf der dem Kammerinneren zugewandten Seite einer durch den Kammerboden (oder zumindest den durch die Schneide kreisförmig zu öffnenden Teil desselben) definierten Ebene oder in dieser Ebene angeordnet ist.
  Dadurch ist es ermöglicht, dass die Öffnung des Bodens durch eine Drehbewegung der Kammer relativ zum Adapter erfolgen kann, ohne dass eine Bewegung der Kammer auf den Adapter zu und/oder in diesen hinein erfolgt oder erfolgen muss. Gemäss einer besonders bevorzugten Ausgestaltung zeichnet sich der Behälter dadurch aus, dass
• die Schneide dazu ausgebildet ist, bei Drehung der Kammer den Boden der Kammer entlang seines Randes nur teilweise von der Kammer zu lösen, wobei zu diesem Zweck die Drehung der Kammer relativ zum Adapter in Bezug auf den maximalen Drehwinkel begrenzt ist,
• das mit dem Adapter verbundene Schneidelement eine Durchflussöffnung für die Mischkomponente aufweist, wobei die Schneide am Rand der Durchflussöffnung angeordnet ist,

• die Kammer an ihrer Aussenseite einen Vorsprung aufweist, wobei ein äusserer Durchmesser der Kammer am Ort des Vorsprungs grösser ist als ein innerer Durchmesser des Adapters auf der der Kammer zugewandten Seite, wobei der Vorsprung die Kammer zumindest teilweise entlang ihres Umfangs umgibt.

More generally, it may be advantageous for the cutting element and / or the cutting edge to be wholly or partially:

• within the side wall of the chamber or within the prismatic body defined by the side wall of the chamber (in particular circular cylinder) and / or
• on the side facing the chamber interior of a plane defined by the chamber bottom (or at least the part of the same by the cutting edge to be opened) or in this plane is arranged.
  This makes it possible that the opening of the bottom can be carried out by a rotational movement of the chamber relative to the adapter, without a movement of the chamber to the adapter and / or into this takes place or must be done. According to a particularly preferred embodiment, the container is characterized in that
• the cutting edge is adapted to release the bottom of the chamber along its edge only partially from the chamber upon rotation of the chamber, for which purpose the rotation of the chamber relative to the adapter is limited with respect to the maximum angle of rotation,
• the cutting element connected to the adapter has a flow opening for the mixing component, wherein the cutting edge is arranged at the edge of the flow opening,

• the chamber has on its outer side a projection, wherein an outer diameter of the chamber at the location of the projection is greater than an inner diameter of the adapter on the side facing the chamber, wherein the projection surrounds the chamber at least partially along its circumference.

It also discloses the use of the container described in this document or a method of adding a mixing component to a second container using the container described in this document.

In the aforementioned method or the above-mentioned use, it is preferred when the adapter is fastened (in particular screwed) to the opening of the second container by means of the second connection means, the chamber is rotated relative to the adapter or at least moved toward and / or into it the blade opens the bottom of the chamber and the mixing component flows from the chamber via adapter into the second container.

According to a preferred embodiment, said use or method as steps includes one or more actions described in the form of suitability, capabilities or characteristics of the container.

In addition, a method for filling the container described in this document with a mixing component is disclosed. This method is advantageously characterized in that the filling of the chamber with the mixing component takes place through a second opening (filling opening), which is different from the opening in the flow channel, which is or will be closed by the floor. Ideally, the filling opening is opposite the opening in the flow channel. After filling the container or the chamber with the mixing component, the filling opening may be closed, for example, by a sealing film, in particular a heat-sealing film. Optionally, the closure of the filling opening can be opened or removed after the bottom of the chamber has been opened by the cutting edge and the mixing component has been fed through the thus formed opening in the flow channel to the second container. Said second opening, ie the (former) filling opening can then be used as a pouring opening for the contents of the second container. This can be dispensed with a removal of the container from the second container for pouring the contents of the second container. Also, the pouring opening can in turn be closed by a closure such that after each removal of a subset of the second container via the pouring opening of the container, this pouring opening is closed.

Embodiment of the invention

The invention will be explained by way of example with reference to the drawings.

Fig. 1a and 1b show an embodiment of a proposed container 11 as an attachment for a second container 13, which is formed in the present embodiment as a bottle. The container 11 has a chamber 21 for receiving a mixing component and a designated as adapter 51 part. The adapter 51 serves on the one hand the connection of the container 11 with the second container 13 in order to admit the mixing component to the latter. On the other hand, the adapter 51 fulfills the purpose of opening the chamber 21 of the container 11 and thus releasing the mixing component, so that it can flow through the adapter 51 into the second container 13. The adapter 51 is connected to the chamber 21 via a first connection means 61 and also has a second connection means 63 for attachment to the second container 13. The second connecting means 63 is preferably a thread, in particular an internal thread, for attachment to a corresponding thread, in particular an external thread, at the opening of the second container 13. The latter is usually a bottle with a neck or neck, having the thread described. The first connecting means 61 allows movement of the chamber 21 on the adapter 51 to. In the present example, the chamber 21 is movable into the adapter 51, wherein the first connecting means 61 forcibly guided during the approach of the chamber 21 and the adapter 51 generates a rotational movement of the chamber 21 relative to the adapter 51. Conveniently, both the adapter 51 and the chamber 21 are formed substantially cylindrical at their ends facing each other, wherein at the described ends of the outer diameter and the outer contour of the chamber 21 substantially corresponds to the inner diameter or the inner contour of the adapter 51. As a result, the chamber 21 is partially slidable and rotatable in the adapter 51, ie in its one opening 55. At the end facing the adapter 51, the chamber 21 has a bottom 23 with one or more weakening areas or thinning 25. Conveniently, the weakened region 25 is substantially circular. It preferably runs essentially along the inner edge of the chamber 21 or at least at a substantially constant distance to it. The weakened region 25 is designed to cooperate with a cutting element 71, which is arranged in the adapter 51 between the first connection means 61 and the second connection means 63. The cutting element 71 is preferably stationary and / or immovable relative to the adapter 51, wherein it is preferred if the cutting element 71 is part of the adapter 51 and / or if the cutting element 71 and the adapter 51 are integrally formed. If the chamber 21 is now moved toward or into the adapter 51, the bottom 23 comes into contact with the cutting element 71, ie with its cutting edge 73, namely at the location of the weakened region 25. As a result of the rotational movement of the chamber 21 the cutting edge 73 is guided along the weakening region 73 and opens the bottom 23 of the chamber 21 circular. Preferably, in the end position of the cutting edge 73 (ie, when the bottom 23 is fully opened), the bottom 23 remains connected to the chamber 21 at one location. The remaining connection between the bottom 23 and chamber 21 allows a Hineinklappen the bottom 23 in the chamber 21 or a fold out of the chamber 21. The bottom 23 is thus opened without it drops and possibly lost. To achieve this, various possibilities come into consideration. Conveniently, the movement of the chamber 21 into the adapter 51 and / or the rotational movement of the chamber 21 is limited. This can be done, for example, by the first connection means 61. However, the movement of the chamber 21 into the adapter 51 can also be limited by the cooperation of a projection 41 with the edge 59 of the adapter 51. The projection 41, formed in the present example by an extension of the chamber 21, extends circumferentially on the side wall 31 of the chamber 21. When moving the chamber 21 in the direction of the adapter 51, the projection 41 approaches the edge 59 of the adapter 51. The distance between the projection 41 and edge 59 thus defines or limits how far the chamber 21 can be moved into the adapter 51 or the projection 41 forms a stop. In the unopened state, a spacer 17 may be provided between projection 41 and edge 59, which prevents an approach of the projection 41 and the edge 59 and thus an approximation of the cutting element 71 and the bottom 23 of the chamber 51. The spacer 17 is removable, in particular removable by hand, formed. The cutting element 71 has an opening 56 which allows the passage of the mixing component flowing from the bottom 21 into the adapter 51 from the bottom 23 towards the opening 56, which opens into the opening 54 of the second container 13. The opening 56 of the cutting element 71 narrows in the direction of flow of the mixing component, ie in the direction from the chamber 21 to the second container 13. The cutting element 71 forms a funnel 75, with its opening width on the side facing the second container 13 is preferably smaller As the opening width of the opening of the second container 13. In the example shown, the neck or the neck of the second container 13 is accommodated (in the (end) state connected to the adapter 51) between the side wall 53 of the adapter 51 and the funnel 75. This prevents the mixing component from entering the region of the second connecting means 63, as a result of which the bottleneck of the container 13 would become contaminated. This is particularly important when the container 11 is removed after the addition of the mixing component to the second container 13 shall be. Because there are two main uses. According to a first variant of the container 11 is connected to the second container 13 and after addition of the mixing component is a cover 49 (alternatively, a film), which closes the opening 27 of the chamber 21, removed and present in the second container 13 mixture can the opening 54 of the second container 13 via the adapter 51 and the chamber 21 are poured out. In this case, the container 11 preferably has a fuse which prevents removal of the container 11 from the second container 13. According to a second variant, the container 11 is removed from the second container 13 after the addition of the mixing component. In this case, the opening 27 or the presence of the removable cover 49 or the film is not necessary. Dirt on removal of the container 11 can be avoided by the smaller opening width of the opening 56 compared to that of the opening 54 of the second container 13 (regardless of the presence of a funnel 75). Further improvement is achieved by the presence of the described funnel 75. Alternatively or additionally, it may be provided (irrespective of the funnel shape) that the opening 56 of the cutting element 71 has an edge protruding into the opening of the second container 13, as in FIG 1a and 1b is shown (in the opening of the second container 13 projecting cutting element 71). An improved tightness is also achieved by the described measure and thus the avoidance of contact of the mixing component with the second connecting means 63. Other measures to improve the tightness include the seals 28 and 29. The seals 28, 29 are preferably annular. The seal 28 extends along the weakened region 25 and may be formed as part of the bottom 23 as in the present embodiment. It comes into contact with the cutting edge 73 before or while the cutting edge 73 comes into contact with the bottom 23 and / or begins to open the bottom 23. For example, the weakening portion 25 may be formed as a portion of the bottom of lesser thickness, for example, the seal 28 may be closer to the cutting element 71 than the portion of the bottom 23 contacting or cutting the blade 73. The thinner portion of the bottom 23 may be located farther away from the cutting edge 73. Another seal 29 is formed by the projection 41, which can also be arranged on, at, beside or along the projection. Only relevant is that the edge 59 at maximum approximation (or minimum distance) of the chamber 21 and the adapter 51 sealingly with the projection 41 and with the part of the chamber 21, with which the edge 59 is in contact in this position, cooperates sealingly.

The 2a and 2b present a slightly modified version of the container 1a and 1b dar. A difference to the embodiment according to 1a and 1b is in the form of the chamber 21. The chamber 21 is extended on the side remote from the adapter 51 side. In particular, the inner diameter of the chamber 21 at said end is greater than the outer diameter of the adapter 51. In this way, a substantial increase in volume can be achieved without the length of the container 11 increases greatly.

The Fig. 3a and 3b show two different views of the outside of the chamber 21 (corresponding to the in the 1a and 1b represented chamber). The first connection means 61 or the part thereof, which is arranged on the chamber 21, is clearly visible. This has a (first) guide track 33 which extends helically or helically along the outer side or side wall 31 of the chamber 21. Conveniently, such a guide track 33 rotates the chamber less than twice, in particular less than once, and preferably about half a time. This guideway 33 defines in the present embodiment the necessary for a complete opening of the chamber 21 rotation angle of the chamber 21 relative to the adapter 51. In particular, the guide rail 33 forms at its end a stop 76 for the sliding projection 57 described below, whereby the angle of rotation is limited , Conveniently, two or more such guideways 33 are provided, which may be arranged at regular intervals along the circumference of the chamber 21. In 3a and 3b For example, two guideways 33 of this type are provided on opposite sides of the chamber 21. This helical guideway 33 serves to screw the chamber 21 into the adapter 51 and so the bottom 23 of the chamber 21 in contact with the cutting edge 73 and to move them along the weakening area 25 to open the bottom 23. For this purpose, the adapter 51 with a sliding projection 57 (see. Figure 4 ) per guideway 33 equipped. This moves with rotation of the chamber 21 along the helical guide rail 33 and thus causes a connection between the chamber 21 and the adapter 51, which allows the above-mentioned rotation of the chamber 21 relative to the adapter 51. Conveniently, a step 37 is provided on the bottom 23 nearer and / or at the bottom 23 of the helical guide track 33, which counteracts the movement of the sliding projection 57 in the guide track 33 (or beyond the step). After overcoming the resistance, in the present embodiment by a rotation in a predetermined direction, the sliding projection 57 reaches a corresponding to the sliding projection 57 formed pocket 77. In the direction of rotation of the stop 76 is arranged, which prevents further rotation of the sliding projection 57. Contrary to the direction of rotation, the step 37 is designed in such a way that the sliding projection 57 can leave the pocket 77 positively guided in the direction of the helical guide track 33 under resistance, but non-destructive. Depending on the configuration of the step 37, the sliding projection 57 can be fixed reversibly or irreversibly in the pocket 77. The steps 37, or the pockets 77 in conjunction with the sliding projections 57, cause a stabilization or fixation of the position of the chamber in its closest to the adapter 51 and / or farthest position. Optionally, one more (preferably shorter) guide track 35 is provided for each helical guide track 33. This second, shorter guideway 35 also extends along the circumference of the chamber 21 on the outer side 31, but expediently at a constant distance to the bottom end of the chamber 21. The shorter guideway 35 is in the helical guideway 35, in the area of the farther from Bottom 23 of the chamber 21 remote end of the helical guideway 35. This results in a bifurcation. If the chamber 21 is rotated after rotation and opening of the bottom 23 in the opposite direction, the sliding projection 57 moves from the end of the helical guide rail 33 ago in the shorter guide rail 35 and reaches its free end, which has a stop 76 for the sliding projection 57 forms and so a transfer of Torque on the adapter 51 allowed. In this way, the chamber 21 and the adapter 51 can be removed or unscrewed by rotation of the chamber 21 from the second container 13 alone.

In the embodiment shown here, the chamber 21 and the adapter 51 with cutting element 71 are each in one piece and formed of plastic as a plastic injection molded part, so that here inexpensive large quantities can be produced.

5a and 5b show a preferred embodiment of a container. Its peculiarity lies in a niche 22 formed by the chamber 21, in which the cutting edge 73 is arranged before the opening of the bottom 23 through the cutting edge 73. For clarity, the cut edges are hatchless. The niche 22 may be formed by the bottom 23 and / or the side wall 31 of the chamber 21. The parts of the chamber 21 which form the niche 22 may also be referred to as a niche wall. Generally speaking, it may be advantageous if the cutting edge 73 extends from one side of the plane 30 defined by the circularly openable part of the bottom 23 to the opposite side of this plane 30, before the opening of the bottom 23 by the cutting edge 73 of the cutting element. This makes it possible that the opening of the bottom 23 by a rotational movement of the chamber 21 relative to the adapter 51 can be carried out without a movement of the chamber 21 to the adapter 51 to and / or into this takes place or must be done. If the cutting edge 73 is rotated relative to the adapter 51, it first cuts through the niche wall. As the niche wall merges into the bottom 23 of the chamber 21, the cutting edge 73 then slides into the bottom 23 and cuts it along its edge. A part 24 of the niche wall remains connected to the bottom 23 and the side wall 31 of the chamber 21. In this case, a rotation angle of the chamber 21 relative to the adapter 51 may be limited. Since the bottom 23 remains connected to the side wall 31 of the chamber 21, it can not be lost or get into the second container, even if the angle of rotation of the chamber 21 relative to the adapter 51 is greater than 360 °. The niche 22 may also generally be a cavity.
