    [0001] The invention relates to a double cartridge, with two supply containers that in each case have an anterior end with an outlet connection piece, the longitudinal axes of the outlet connection pieces extending , at least mainly, in parallel. In addition, the invention relates to a mixer with a housing, which defines a mixing chamber, with an outlet opening at one end of the housing, and at its opposite inlet end, two connection pieces, which end in the mixing chamber, whose longitudinal axes extend, at least substantially, in parallel. In particular, the mixer can be connected with the double cartridge in order to mix the substances contained in the double cartridge and to distribute the mixture. To this end, the inlet connection parts of the mixer can be connected with the outlet connection parts of the double cartridge.
    [0002] These types of systems are used, for example, in dentistry, to store and process components for filling materials, filling materials, adhesives or similar. Therefore, the components are stored separately in supply containers and can be discharged via the outlet connection piece in the mixer by a corresponding dispensing device, using dispensing pistons or pistons. The mixer can be a static mixer or a dynamic mixer, in which a mixing element is displaced within the housing by an axis of the dispensing device.
    [0003] In most distribution devices available on the market, the cartridges are stored at an angle, such that the outlet connection parts tilt down. This makes it easier, for example, to fill a printing tray with the mixed components, which are being unloaded from the mixer. But at the same time, it is inherent in this configuration that the outlet connection parts and, perhaps, mixer shaft are not easily visible to the user, so that sometimes it is difficult to assemble a new mixer on the double cartridge , before each use.
    [0004] Thus, in EP 2 335 641 A1, there is described a double cartridge and a static mixer, which can be connected with it, in which the mixer and the double cartridge are fixed by a bayonet connection, which is provided in a cover, which surrounds a coupling element, which mainly consists of an inlet connection piece and a mixing coil and the mixer housing and can be rotated in relation to it. In this mixer, the coupling element is pivotally mounted on the mixer housing. A similar solution is known from WO 2011/041917 A1, with the bayonet connection means having a rotation guide mounted transversely, with the effect that during the establishment of the connection, the mixer is inevitably brought close to the cartridge and that when the connection is released, the mix inevitably rises from the cartridge. Before fitting these (bayonet) connection means, they must first be inserted into each other, with coding means ensuring that the mixer housing is specifically aligned with the cartridge. In other words, the mixer must first be placed on the cartridge, until the inlet openings of the mixer are connected with the outlet connection parts of the cartridge, before the mixer can be locked by a rotation with the cartridge, for example, by bayonet mounting means, configured as a rotating nut.
    [0005] A specific alignment of the mixer with respect to a cartridge is also the subject of EP 0 730 913 A1, which has encoding means similar to EP 2 335 641 A1 or WO 2011/041917 A1. However, these coding means are better suited for aligning a mixer housing or bayonet ring in relation to the cartridge, without thereby also inevitably aligning the cartridge outlets with the mixer inlets.
    [0006] Thus, in the solutions according to EP 2 335 641 A1 and WO 2011/041917 A1, the connection between the mixer and the cartridge requires visual control and precise assembly of the mixer in a previously defined position. This is sometimes perceived as bothersome and impractical. In addition, in mixers according to the prior art, a specific alignment of the coupling element in relation to the mixer housing is already necessary during the installation of the mixer, because otherwise the mixer could not be mounted on the cartridge. This requires an expensive, additional installation step, including the necessary quality control. If the coupling element is rotated unintentionally in relation to the mixer housing, despite this prior alignment, the mixer can no longer be mounted on the cartridge, unless these two components are previously manually aligned again. In addition, the bayonet mounting means, known from EP 2 335 641 A1 and WO 2011/041917 A1, which fits only in two positions, proved to be disadvantageous, particularly, due to the high distribution pressure, which is generated when paste-like masses are distributed and / or at high distribution speeds.
    [0007] In addition, there is a combination of a mixer, a bayonet ring such as a swivel nut and a cartridge, which is offered by Sulzer Mixpac AG (CH-9469 Haag) under product numbers MBD 381-05-00 (mixer), BBD 381-00-11 (bayonet ring and CBD 381-00-58 (cartridge). A very similar combination is also described in EP 1 943 012 B1. With it, the mixer has a cover or a coupling element, consisting mainly of the inlet connection parts and a mixing coil, a mixer housing and a mixing element which is rotatably mounted on the coupling element. Inlet connection parts of the mixer on the side of the cartridge facing the coupling element, which can be loosely engaged with a recess in a plate, which is attached to the outlet connection parts of the cartridge. input and output and the The coding is, therefore, dimensioned in such a way that when a mixer is placed on the hinge cartridge, the input connection pieces are already inserted in the output connection pieces, before the coding element reaches the recess in the plate. Neither the coding element nor the recess in the plate can therefore function as a guide for the mixer when the cartridge is assembled, but only prevent the mixer from being locked by the bayonet ring on the cartridge, when the mixer is placed on the cartridge, rotated 180 °, that is, the wrong input and output connection parts fit together. Regardless, even the large gap between the coding element and the recess in the plate does not allow any guide of the mixer in the cartridge.
    [0008] EP 1 440 737 A1 shows a system with coding means, which are configured as guide rails, which fit into recesses which are located at a distance from the cartridge outlets. The coding means can only prevent incorrect assembly of the mixer, without, however, facilitating the placement of the mixer without visual control.
    [0009] In contrast, the present invention is based on the objective of providing a cartridge and a mixer that are easier to connect to each other.
    [00010] According to the invention, this problem is solved, essentially, by a double cartridge with the characteristics of claim 1, and a mixer with the characteristics of claim 6. Therefore, the invention is based on the idea of providing an independent guide the outlet connection parts and inlet connection parts of the double cartridge or mixer, which must be connected with each other, which facilitates the exact positioning of the mixer in relation to the double cartridge. In other words, the guide must ensure that the inlet connection parts of the mixer can be inserted into the outlet connection parts of the double cartridge, even when a view of the outlet connection parts is difficult or not possible, due to the location the distribution device. Thus, even intuitive, purely tactile identification of the correct mixer position is possible. Thus, it is particularly preferred that, at the same time, a mixer shaft, possibly present, of the dispensing device, can also be connected with the mixer.
    [00011] In this regard, it is provided according to the invention that the outer casing surface of the outlet connection parts of the double cartridge and / or a plate formed in an outlet connection part, in each case, at least a projection is located in such a way that a guide channel is formed between the projections or a projection defines a guide channel, which extends, at least mainly, parallel to the longitudinal axes of the outlet connection parts. Depending on the size and alignment of the protrusions, the length of the guide channel parallel to the longitudinal axes of the outlet connection parts can also be very short, for example, if the protrusions are approximately punctate. This also includes modalities, in which the connection parts of the cartridge outlet end in a plate or are surrounded by a plate, an opening in that plate then defining the guide channel. In this case, the thickness of the plate defines the length of the guide channel. On the side of the plate facing out of the mixer, additional guide elements may be provided in order to increase the length of the guide channel. In addition, the invention is not limited to the model of a single guide channel, but instead several guide channels can be formed, with which, in each case, a guide rib or similar of the mixer can engage. if. This latter model is preferably appropriate when the cartridge outlet connection parts end on a plate, or are surrounded by a plate.
    [00012] Within the scope of this invention, a double cartridge is, for example, a unit consisting of two containers joined integrally to a piece. As an alternative to this, the double cartridge can also be formed by two individual containers, in particular, flexible tube pouches, in each case, provided with rigid caps, with which these individual containers can be connected with each other. This can be achieved, for example, by inserting the containers into two connected tubes, which function as a support cartridge. In this case, it is preferred when the individual containers or their lids that have, in each case, an outlet connection piece for the substances contained in the respective tube bags or similar, can be aligned in relation to each other, in such a way that the projections provided in each case on the outer casing surface of the outlet connection pieces are located in such a way that a guide channel is formed between the projections, which extends parallel to the longitudinal pebbles of the outlet connection pieces, particularly , by a corresponding configuration of the support cartridge.
    [00013] According to a preferred embodiment of the invention, at least one of the projections is configured as a guide bar, which extends, at least substantially, parallel to the longitudinal axes of the outlet connection parts. In this case, a guide bar is a projection with a main extension direction, which is essentially aligned parallel to the longitudinal axis of the respective outlet connection piece. These types of guide bars allow an especially good guide of a mixer, I can be connected with the double cartridge, without risk of turning the mixer.
    [00014] As an alternative or in addition to this, at least one of the projections can be configured as a cam, which extends substantially at a right angle to the longitudinal axes of the outlet connection parts. This makes it possible that the projection, in addition to its function and guiding the mixer, also serves as a support for a mixer and / or as a locking element for the double cartridge, for example, by a spring or hitch lock.
    [00015] Preferably, the projections are located on the side of the outgoing connection parts facing the user, while the double cartridge is in use. In this way, on the first side of the double cartridge, a retaining clip may be provided to fix the mixer on the outlet connection parts, with which the projections are then also located on that first side of the outlet connection parts.
    [00016] With respect to filling, stability during distribution of components and also with respect to handling, it has been shown that it is especially appropriate if the double cartridge has a support cartridge, in addition to the supply containers, the containers being supplies are preferably housed in a detachable manner. In this way, the support cartridge can be formed by two tubes, particularly rigidly connected, consisting of metal, or a material composed of fibers. In this case, it is possible to produce the supply containers with comparatively thin walls and consisting of a cost efficient material and / or a material that can be processed advantageously, since at least the forces acting in the radial direction can be essentially absorbed by the support cartridge.
    [00017] By improving this idea according to the invention, it is envisaged that the supply containers are at a distance from each other and are connected integrally in one piece only at its rear end by a bridge. In this way, it is possible to insert the double cartridge supply containers into the support cartridge at one rear end with respect to the direction of distribution, until the outlet connection parts protrude out of the support cartridge at the opposite end. The bridge, by means of which the two supply containers are connected, in this case, serves simultaneously to support the axial loads, which act on the supply container when distributing the components out of the double cartridge. In addition, the supply containers can also be supported on the front end of the support cartridge, in the direction of distribution.
    [00018] According to another embodiment of the invention, the cartridge is provided with a plate or a disc, which is located on the outlet connection parts. Preferably, the outlet connection pieces end on this board or are aligned with it. Alternatively, the outlet connection parts in the direction of the mixer may also protrude beyond the plate. The plate or disk thus forms, for example, projections connected integrally in one piece, between which a guide channel can be formed as an opening in the plate. In addition, other projections or bars may be provided on this plate or disc, which also contribute to the mixer guide. These additional bars can be directly connected to the output connection parts, or they can be located a short distance from them on the board. In that case, distortions during injection molding can be avoided.
    [00019] In an improvement of this modality, a ring or, similarly, a flange-like edge on the plate is preferably provided. The ring preferably protrudes out of the plate towards the mixer, in which case it can form an adapter for the cartridge side of the mixer. A particularly simple and at the same time stable assembly of the mixer in the cartridge can be achieved by the fact that the ring has a thread on its outer side, into which an external thread of the mixer can be screwed.
    [00020] Regardless of the characteristics cited previously, a special aspect of the present invention resides in the fact that means are provided in the cartridge that lift or release the mixer from the cartridge, particularly by means of a relative rotary movement of the mixer or mixer housing in the cartridge. This is advantageous, for example, when the mixer adheres or glues on the cartridge, after the mixture has hardened. Such types of means for lifting the mixer may include, for example, a threaded connection between the mixer housing and the cartridge, so that the mixer also performs a relative axial movement relative to the cartridge, when the mixer housing is rotated. Alternatively or in addition to this, one or more internal inclinations may be provided in the mixer and / or in the cartridge, which facilitate the lifting of the mixer. In particular, these internal inclinations may be provided on a plate on which the outlet connection parts end, and / or on a ring that surrounds that plate.
    [00021] At its inlet end, the mixer according to the invention has at least one guide rib, which extends at least mainly, parallel to the longitudinal axes of the inlet connection parts. In other words, at least one guide rib protrudes from the rear end of the mixer, which faces the double cartridge during use, which can be guided between the projections of the outlet connection parts of the double cartridge, in such a way that the inlet connection parts of the mixer meet the outlet connection parts of the double cartridge.
    [00022] If the mixer according to the invention is a dynamic mixer, whose mobile mixing element is connected with a mixing axis of the dispensing device, it has proved to be especially advantageous if the guide rib has approximately a recess approximately U-shaped. It preferably extends to an edge of the guide rib, which extends outward from the outlet end. In this way, the recess prevents the guide rib from covering the mixer shaft, so that it is possible for a user to continue to verify the correct mixer rod alignment while the mixer is being assembled. As an alternative to the configuration of the guide rib with a recess, it is also possible for two guide ribs, which are at a distance from each other, to extend out of the rear side end of the mixer, so that a recess remains between these two guide ribs through which a mixer rod is visible.
    [00023] When at least one rib protrudes over the inlet connection parts of the mixer, it is possible to guide the mixer in relation to the double cartridge, even before the inlet connection parts of the mixer come into contact with the parts of the mixer. double cartridge outlet connection. In this way, it is possible that a user only needs to align the mixer in such a way that the guide rib is inserted in the guide channel formed between the projections, in order to be able to mount the mixer in the double cartridge. This makes handling the mixer significantly easier.
    [00024] The guide rib of the mixer can also be configured in an arcuate or curved way. For example, in cross-section, the guide rib can extend perpendicular to the axis of the mixer almost like a circular segment around the axis of the mixer.
    [00025] Regardless of the characteristics mentioned previously, it is preferred if the mixer has a housing that can be rotated in relation to the mixer cover, which is provided with the inlet connection parts. In this configuration, the mixer housing can be provided with an external thread, to make it possible to screw the mixer, for example, in a ring on the cartridge, while simultaneously the inlet and outlet connection parts engage up on each other.
    [00026] Another aspect of the present invention resides in the fact that means are provided in the mixer, which lift or release the mixer from the cartridge, when a relative movement, particularly a relative rotation of the mixer or the mixer housing, with respect to to the cartridge. Such types of means for lifting the mixer may, for example, include a threaded connection to the mixer housing and the cartridge and / or internal slopes, which may work in conjunction with corresponding counter-contours of the cartridge.
    [00027] Furthermore, the invention relates to a combination, which consists of a double cartridge of the type mentioned above, with a mixer of that type. This combination or set means an arrangement and distribution, which consists of a double cartridge and a mixer, which is connected with it or can be detachably connected with it. In this way, the width of the guide channel that is formed between the projections is preferably coordinated with the width of the guide rib or the distance of the guide ribs in the case of two guide ribs, so that the mixer is guided by the guide rib (s) and the guide channel in relation to the double cartridge and can be mounted on it. In other words, in the distribution arrangement according to the invention, the mixer guide rib (s) and at least one guide channel of the cartridge are first joined, before, when a mixer is being mounted on the cartridge, the inlet connection parts and the outlet connection parts also engage with each other.
    [00028] Next, the invention is explained in more detail, with the help of an exemplified modality and by reference to the drawing.

    [00029] The cartridge configuration illustrated in fig. 1 essentially has a double cartridge 1 and a support cartridge 2. In that case, the double cartridge 1 can be detachably connected with a mixer 3.
    [00030] As can be seen in Figures 3 and 4, the double cartridge 1 essentially consists of two separate supply containers 4, 5, whose housing is essentially cylindrical. The front end of the supply containers 4, 5 shown in Figure 1 on the left is closed by a front wall that is dimensioned sufficiently thick to also withstand high forces during the distribution of the components. In each case, an outlet connection piece 6 or 7, which forms an outlet opening of the respective supply container, protrudes from that front wall. In the illustrated embodiment, outlet connection parts 6, 7 are located closely adjacent, that is, not centrally on the front wall of the supply containers. This makes it possible to configure the mixer 3 in a comparatively compact way, since its input connection parts 3a, 3b do not need to have a large distance between them. On the opposite rear side, the supply containers 4, 5 are open, so that dispensing pistons 8 - explained in more detail below - can be inserted to seal the supply containers. Dispensing pistons simultaneously serve to dispense the substances or components of the compression material or the like, which is contained in the supply containers 4,5 through the outlet connection parts 6, 7.
    [00031] At its rear end, the supply containers 4, 5 are connected by a bridge 9. The bridge 9 is configured in a piece with a flange-like edge 10, which protrudes over the rear end of the supply containers 4 , 5. At the front end of the two supply containers 4, 5 a rotatable groove 11 is provided on the front wall which serves as a stop for the support cartridge 2.
    [00032] In the illustrated modality, the bridge 9 is provided with a latching lever 12, which is configured in one piece with the bridge 9 and the filling containers 4, 5. At the front end of the latching lever 12 - in the direction of distribution - a coupling hook is provided, the function of which is explained in more detail below.
    [00033] The outlet connection parts 6, 7 of the supply containers 4, 5 can be connected with the mixer 3, which is a dynamic mixer, that is, operated electrically, in the mode that is illustrated. To that end, the inlet connection parts 3a 2b of the mixer are inserted into the outlet connection parts 6, 7. As can also be seen in the detail view in Figure 5b, a guide rib 13 is formed in the mixer 3 , which protrudes out of the rear end of the mixer 3 towards the double cartridge1. A cam 14 is provided in a given outlet connection piece 6, k 7, which together form a guide channel 14b, the width of which is dimensioned in such a way that the guide rib 13 of the mixer is guided between the two cams 14, when the mixer 3 is mounted on the outlet connection parts 6, 7. In the shown mode, a guide bar 14a is additionally provided on each outlet connection part 6, 7, which extends in axial direction and cooperates with the guide rib 13 of the mixer 3. The cams 14 and guide bars 14a, which together define the guide channel 14b, thus facilitate the precise assembly of the mixer 3 by cooperation with the guide rib 13. A Inserting a mixer shaft from a dispensing device into a corresponding mixer adapter 3 - not shown in the figures - can be facilitated by the fact that in the guide rib 13 of the mixer 3 a recess 13a is provided, which frees the visualization of the mixer adapter 3, which is configured, for example , with a hexagonal recess.
    [00034] The illustration in Figure 5a shows that the guide rib 13 of the mixer 3 is guided in a guide channel 14b, when the mixer is assembled, even before the outlet connection parts 6, 7 come into contact with the connection and input parts 3a b. This facilitates the insertion of inlet connection parts 3a, 3b in outlet connection parts 6, 7. In addition, in outlet connection parts 6, 7 on the bottom side in Figure 5a, a barrier or a stop may be provided (not shown), which prevents assembly of the mixer rotated 180 °. In other words, this barrier or stop can prevent the input connection part 3a from coming in contact with the output connection part 7, or that the input connection part 3b from contacting the output connection part 6 For this purpose, the barriers or stop are preferably located in such a way that the guide rib 13 of the mixer would abut them, before the connection and inlet parts and the outlet connection parts come into contact. .
    [00035] Another function of the cams 14 can be seen in Figure 4, in which a locking plug 15 is inserted at the front end of the double cartridge 1. It has a plate or bar, from which two pins protrude towards to the double cartridge 1, which can be hermetically inserted into the outlet connection parts 6, 7. The locking plug 15 also has hooks 16, which engage behind the cams 14 in outlet connection parts 6, 7, when the locking cap 15 locks the two outlet connection pieces. To release the coupling, a maneuver splint 17 is provided, which can be pulled towards the right in the direction of distribution, that is, in Figure 4, towards the right, to first release the coupling and then pull the locking plug 15 out of the outlet connection parts 6, 7. Since the locking plug 15 simultaneously locks the two outlet connecting parts 6, 7, the locking buffer 15 also provides reinforcement or stabilization of the double cartridge 1, whose supply containers 4, 5 are connected, in the rest, to each other, exclusively by the bridge 9. In the illustrated embodiment, the support cartridge 2 is formed by two metallic tubes connected in one piece, which are open on both sides. The tubes, which consist, for example, of aluminum, have a wall thickness of approximately 1 mm to approximately 2 mm, particularly approximately 1.3 mm. At the left front end in Figure 1, these support cartridge tubes 2 are provided with a collar 18, which protrudes inwards, at least in sections, which can cooperate with the groove of the double cartridge 1 to support the double cartridge 1 in the support cartridge 2. In addition, the length of the double cartridge 1 is adapted to the length of the support cartridge 2, such that the bridge 9 or flange-like edge 10 at the rear end of the double cartridge1 abuts the rear end of the respective cartridge. tube of the support cartridge 2, when the double cartridge 1 is inserted in the support cartridge 2. As a result, the double cartridge1 is supported and fixed in the feed direction of the distribution pistons 8 in the support cartridge 2, at both ends .
    [00036] Alternatively to the illustrated embodiment, the support cartridge 2 may be provided with a front wall., Which replaces the collar 18, which protrudes inwards, or is supported by it. This front wall or plate can also be screwed or glued to the support cartridge 2. As a result of a front wall, the double cartridge 1 is still better supported on the support cartridge 2. The wall can have openings, which make it possible the penetration of the outlet connecting parts 6, 7, or connecting parts, which can accommodate the outlet connecting parts 6, 7, can be provided on the wall itself.
    [00037] In addition, each tube of the support cartridge 2 has a window 19, through which the double cartridge 1 is feasible from the outside. This also makes it possible to identify, for example, a color marking or similar coding on the double cartridge, by inspection through the window 19.
    [00038] In the support cartridge 2, in a section between the two tubes, an opening is provided to receive an adapter rail 20. The adapter rail 20 can be inserted in this opening and is fixed in it using a screw 21.The rail adapter 20, like support cartridge 2, can consist of metal, particularly aluminum or, preferably, plastic.
    [00039] In addition, the support cartridge 2 can be provided with a retaining clip 22, which can be rotatably attached to a joint 23 on the adapter rail 20. The retaining clip 22 has a retaining section approximately in shape of U, which can surround the mixer 3 in sections and, thus, mount it on the outlet connection parts 6, 7. Using a hook 25, the retaining clip 22 can be fixed on an adapter rail 20 or in the support cartridge 2 in its position, which fixes the mixer3. In order to rotate the retaining clip out of its engaging position (Figure 2), which extends approximately parallel to the tubes of the support cartridge, to a position for releasing the mixer (Figure 3), a button is provided release 26, which can rotate the latch hook 25 to a position that releases the latch. As a result of a spring 27, shown in Figure 1, the retaining clip 22 can automatically rotate to the position shown in Figure 2, after maneuvering the release button 26, in which it is possible to change or install the mixer 3. An engaging projection is also provided on the adapter rail 20 or support cartridge 2, which extends around the engagement lever 12 of the double cartridge 1, when inserted in the support cartridge 2. With this, the double cartridge 1 it is also fixed against the feed direction of the distribution pistons 8 inside the support cartridge 2. To remove the double cartridge 1 from the support cartridge 2, a user needs to apply pressure to the upper section of the engagement lever 12, to release the hitch.
    [00040] As shown in Figure 6, the distribution pistons are provided, in each case, with two sealing lips 28, molded in one piece, and with two ejector bars 29, which rotate around the outer circumference of the distribution pistons . In addition, a sealing ring is housed in a rotating groove 30, which can be configured, for example, as an O-ring or an X-ring. A ventilation channel extends on each distribution piston 8 and can be sealed using a rotating locking lock 32. To that end, each timing piston has an essentially cylindrical adapter for a rotating locking lock 32. In Figure 6, this adapter has a lip 33 on its top edge, which prevents a movement of the rotating locking latch 32 in an axial direction. In this way, it is prevented that at the very high discharge forces of the dispensing device (distributor) and the associated back pressure of the toothpaste, the rotating locking lock 32 is pushed back again, axially out of the dispensing piston. Otherwise, this would lead to leakage and thus contamination of the distribution device. Alternatively to flange 33, a thread or bayonet connection between the adapter and the rotating locking lock 32 can also be provided.
    [00041] The cylindrical adapter is connected to the internal space of the supply containers 5 through a ventilation opening 34. In addition, in the embodiment illustrated, coupling projections 35 are provided on the inside of the cylindrical adapter on two diametrically opposite sides.
    [00042] The rotating locking latches 33 shown in detail in Figures 7 and 8 have, in each case, a lower groove 36 on the lower side in Figure 6, and four lateral grooves 37, which extend in axial direction, of which, in in each case, two are connected with the lower groove 36, while the remaining two side grooves 37 are not connected with the lower groove 36. On the opposite side to the lower groove 36, each rotating locking lock 32 is provided, for example, with an opening to rotate the rotating locking latch on the cylindrical adapter using a tool. Coupling projections 35 inside the cylindrical adapter thus prevent unintentional rotation of the rotating locking latches 32.
    [00043] On the timing piston on the right in Figure 6, the two side grooves 37, which are not connected with the bottom groove 36, accept lugs, so that through the two side grooves 37, which are connected with the groove bottom 36, a ventilation channel is formed, which is connected to the interior of the supply containers 4, 5 through the ventilation opening 34. In contrast, on the left distribution piston in Figure 6, the rotating locking lock 32 is rotated by 90 °, so that the two side grooves 37, which are connected with the lower groove 36, are locked by latching projections 35. In this way, it is possible to let the residual air escape from the supply containers first, after filling supply containers 4, 5 and insert dispensing pistons 8 and then completely seal the dispensing pistons by maneuvering the rotating locking latches 32.
    [00044] Figures 9 to 11 show another embodiment of a locking plug 15 ', in which maneuvering splints 17 essentially do not protrude beyond the end of the locking plug 15', which faces away from the cartridge. This reduces the risk of damage during transport and reduces the storage space required in the outer packaging. In addition, reinforcement elements 38 are provided, which surround or house the guide bar 14a, in such a way that the torsional stiffness of the double cartridge is improved, when the locking plug 15 'has been inserted. In addition, in Figures 9 and 10, slings can be seen39, which engage with the outlet connection pieces, I lock the containers of the double cartridge, when the locking plug 15 'has been inserted.
    [00045] In the illustrated modes, the mixer 3 can be mounted on the cartridge system and can be fixed by the retaining clip22. In addition, or as an alternative to this, the mixer can also be provided with a coupling system, which is configured in a similar way to the fixing of the locking plugs 15 or 15 ’. In other words, even the mixer 3 can be all with hooks 16 and a maneuvering splint 17, for detachable assembly on a cartridge system.
    [00046] In the figures, the double cartridge is shown as a single package. Alternatively, individual containers, such as tubular bags, which are connected to each other or can be connected to each other, can form the double cartridge.
    [00047] According to another preferred embodiment, the wall thickness of the supply containers is less than one tenth of the thickness of the bridge 9, for example, approximately 0.5 mm approximately 1.0 mm, preferably approximately 0 , 7 mm or approximately 0.9 mm. In contrast, the front wall can be approximately 7 mm thick, so that it can absorb greater forces.
    [00048] In addition, it is preferred when a rotating groove is formed on the inner side of the front wall, particularly in the transition section between the front wall and the side wall. In this way, the cartridge 1 according to the invention can then also be emptied to the maximum degree, when pistons 8 (of discharge) are used with a radially external sealing lip 28 pointed in the feeding direction. In this case, the sealing lip 28 can immerse itself in the groove. In addition, the groove offers advantages in injection molding, in the transition between the thinnest side wall and the strongest front wall.
    [00049] In Figures 12a to 12h, several modalities of the adapter section of a mixer shaft 40 are shown to house a drive shaft (not shown). The illustrated internal contours of the adapter sections serve to facilitate, in each case, the insertion of the drive shaft with a hexagonal head, particularly when the hexagonal head of the drive shaft is not aligned with an ideal fit for the corresponding counter-contour in the receiving section , when the drive shaft is inserted into the mixer shaft 40.
    [00050] For that purpose, Figure 12a shows a mixer shaft 40 of mixer 3 (actuated) dynamically with an annular (thinned) phase. To house a torque-proof drive shaft (not shown), the mixer shaft 40 has a hexagonal recess 42, and a ramp 43a is provided, which facilitates the insertion of the drive shaft with the hexagonal head. The ramp 43a slopes inward so that an edge of the hexagonal head of the drive shaft meets this ramp 43a, and the drive shaft, due to the continued insertion of the drive shaft into the mixer shaft 40, is rotated to a surface of the hexagonal head of the drive shaft abut the internal ramp 43a, that is, until the hexagonal head is correctly aligned with the hexagonal recess 42.
    [00051] Instead of a ramp 43a, in the mode according to Figure 12b, triangles 43b are provided between the annular phase (tapered) 41 and the hexagonal recess 42, which facilitate the insertion of the drive shaft with a hexagonal head. Due to the upward angled surfaces of triangles 43 in Figure 12b, in a possible misalignment of the hexagonal head, it can be rotated by continuous insertion of the drive shaft into the mixer shaft 40, until the hexagonal head is aligned with the hexagonal recess 42.
    [00052] A similar modality is shown in Figure 12c, and instead of triangles 43b, in different positions distributed over the circumference, a tapered entrance 43c is provided in each case. In Figure 12d, entrance ramps 43d on one side, which allow the rotation of the hexagonal head in only one direction. In contrast, in Figure 12e, the thinned phase 41 is elongated in relation to the previously mentioned modalities, until it directly forms a ramp that merges into the hexagonal recess 42.
    [00053] The modality of Figure 12f largely corresponds to Figure 12b, with only a triangle 43b being provided. Likewise, the modality of Figure 12h corresponds to a large extent to that of Figure 12d, with only two sawtooth-like tips 43d being provided, but which are facing each other with their inclined surfaces.
    [00054] The modality according to Figure 12g is based on the modality of Figure 12e, with subsequent to the thinning phase 41, a cylindrical guide section 43e is provided, and subsequently, another thinning section 43f, which then it passes into the hexagonal recess 42.
    [00055] In this case, the annular phase 41 first centralizes and guides the drive shaft. Triangles 43 then guide the hexagonal head edges of the drive shaft into the hexagonal recess contour 42 of the mixer shaft 40, while the mixer is stationary, so that it needs to rotate to a maximum of 1/12 to receive the head hexagonal.
    [00056] Differently, from the modalities described previously, the double cartridge 1 according to the invention can also have a thread 44, which is used to fix the mixer 3. In this case, in Figure 13 a double cartridge is shown, in which protrusions , which are provided in outlet connection parts 6, 7, are formed in one piece with a ring or annular segments, which surround the two outlet connection parts. This ring or these annular segments have an external thread 44, on which, for example, a mixer 3 (not shown) and a mixer 3 can be mounted using a coupling nut. A guide rib 13 of a mixer - also not shown - can in this case be guided between the projections 14, such that the mixer is aligned with the double cartridge, such that the inlet connection parts of the mixer find the cartridge outlet connection parts.
    [00057] A similar modality is shown in Figure 14. In this case, the ring or collar 1b at the end of the outlet connection parts 6, 7 is provided with an internal thread 44, in which a corresponding external thread 45 can be screwed on the mixer housing 3. For this purpose, an internal assembly part of the mixer, which also has inlet connection parts 3b of the mixer, is rotatably housed in the mixer housing 3, so that the outer housing can be rotated in to the internal mounting part for screwing into the mixer.
    [00058] The collar 1b, which includes the internal thread 44, can be formed in a piece with a plate 1a, in which the outlet connection pieces end in an aligned way. The projections 14 of the two outlet connection parts 6, 7 thus form the plate 1a together, the guide rib 13 of the mixer engaging with an opening or channel and guide 14b of the plate in order to to align the mixer or its internal mounting part with the double cartridge, such that the inlet connection parts of the mixer meet the outlet connection parts of the cartridge. As can be seen in Figure 14, the width of the guide rib 13 is greater than the diameter of the larger outlet connection parts 6, so that the guide rib 13 cannot be accidentally inserted into a connection piece of output.
    [00059] Figures 15 to 19 show a modality, which is similar to Figure 14, in which, instead of a guide rib 13, two guide ribs 13 are provided, provided at a distance from each other, which can be inserted, in each case, in an opening or guide channel 14b of the plate 1a. In this case, a colored marking can also be used to show the mixer assembly to the user. As can be seen in the cross-sectional views of Figures 18 and 19, regardless of the characteristics previously described, a mixer 3 according to the invention is preferably configured with a mixer housing 3c, which includes an external thread 45 and it forms a 3d coupling section, which is freely rotatable - that is, it can be optionally rotated in both directions - on which a mixer housing 3c is mounted. In this case, the coupling section 3d has at least one guide rib 13 and inlet connection parts 3a and 3b and locks the mixer housing 3c on the side of the cartridge. In addition, mixer shaft 40 can be mounted in the coupling section 3d. In contrast to known solutions, the free rotation of the mixer housing in relation to the coupling section offers the advantage that the mixer can be mounted on the cartridge in any position and the cartridge and the coupling section can freely align with each other, without requiring the user to have direct visual contact, for example, with the input connection parts and / or the guide rib. In addition, in this case, screwing into the mixer is possible, while the inlet and outlet connection parts and the guide rib and guide channel are already engaged.
    [00060] The modality according to Figure 20 shows a similar configuration of mixer 3 with an external thread 45, with the projections or bars that were thread 45 extending only around a part of the circumference of the mixer and the segments threaded rod bars do not overlap each other. On the contrary, free spaces remain between the individual threaded segments. Correspondingly, even for the internal thread 44 of the cartridge, only individual threaded segments are provided, which do not overlap, with free spaces between them. The size of the free spaces is selected, in this case, in such a way that the threaded segments of the external thread fit into the free spaces of the segments of the internal thread and inversely.
    [00061] Although the mixer is threaded on the inner thread 44 of the cartridge, the upper surfaces of the threaded bar segments of the external thread 45 in Figure 20 abut the lower surfaces of the threaded bar segments of the internal thread 44 in Figure 20, in order pull mixer 3 into ring 1b of the cartridge.
    [00062] The threads 44, 45, in this case, are constructed in such a way that they disengage when the mixer 3 is unscrewed or removed, because the segments of the external thread 45, which engage behind the respective threads of the thread internal 44, distance themselves from the respective bottom surface of the threaded bar segments of the internal thread 44. In other words, the mixer 3 cannot initially be lifted from the cartridge or plate 1a by releasing the threaded coupling, in which the connection pieces of output 6, 7 end.
    [00063] But, in some cases, this is desirable, particularly when the mixer is glued to the cartridge, due to hardening mixtures. For this reason, in the inner wall of ring 1b, which surrounds the plate 1a of the cartridge, an internal ramp 46 is configured, which is defined by the head surfaces of several axially extending bars. After the mixer housing has been unscrewed by rotating with respect to the cartridge, until the threaded segments of the two threads no longer overlap, the substantially lower threads of the threaded bar segments of the external thread 45 in Figure 20 come into contact with the surfaces head of the axial bars, that is, with the internal ramp 46, in order to lift the mixer 3 from the cartridge plate 1a, in which the outlet connection parts 6, 7 end.
    [00064] In the mode according to Figure 21, in the transition section between the ring 1b of the cartridge and the plate 1a, in which the exit connection parts 6, 7 end, internal ramps 46 are provided, which can be connected , in each case, with the corresponding threaded segment of the internal thread 44 by a bar extended axially on the inner wall of the ring 1b. From the ends of the threaded segment of the external thread 45, axial bars 47 in the direction of the characteristics on the external surface of the mixer housing. The ends of the cartridge side (bottom side, in Figure 21) of these bars 47 reach the edge on the cartridge side of the mixer housing, or may extend slightly beyond it. Internal ramps 46 and bars 47 have the effect that, after the mixer housing has been unscrewed by rotation with respect to the cartridge, until the threaded segments of the two threads are no longer overlapping, if the mixer continues to be rotated, the ends on the cartridge side of the bars 47 come into contact with internal ramps 46 in order to lift the mixer from the plate 1a of the cartridge. In addition, even the ring (collar) 1b of the cartridge can be provided with axial bars 48k that work together with bars 47 of the mixer 3 such that a rotation of the mixer in the opposite direction of the threads 44, 45, is possible only until mixer 3 can be removed from the cartridge, or lifted by the internal ramp 46.
    [00065] Another embodiment is shown in Figures 22 to 23a. The fundamental structure of the cartridge and mixer, in this case, corresponds substantially to the modality shown in Figure 14. In contrast to this, the threads 44, 45 on the mixer housing or on the cartridge ring 1b are, however, configured such that the thread rotates, that is, the free spaces between the threaded segments, which protrude from the inner wall of the ring 1b or the eternal wall of the mixer housing, are selected wider than the width of the threaded segments. For example, the thread turns can be approximately 2.3 mm wide, while the threaded segments are only 1.55 mm wide. In this case, a gap or free space is created between the individual threaded segments, so that when the mixer 3 is screwed into the cartridge ring 1b (Figures 22 and 22a), only the upper surfaces of the threaded segments of the external thread 45 in the figures, in order to pull the mixer 3 into the ring 1b of the cartridge 3. Conversely, when unscrewing or removing the mixer 3 (Figures 23 and 23a) only the lower surfaces of the threaded bar segments of the external thread 45 in the figures on the upper surfaces of the threaded segments of the internal thread 44 in the figures. As a result, the frictional resistance is significantly reduced.
    [00066] In addition, the outer diameter of the threaded segments of the outer thread can be defined less than the inner diameter of ring 1b on the thread turns and the inner diameter of the threaded segments of the inner thread, defined more than the outside diameter of the mixer housing. As shown in Figures 22 to 23a, in this case, a radial clearance is also created in the thread section 44, 45 between the cartridge ring 1b and the mixer housing, so that the mixer 3 is guided in the cartridge exclusively by rib guide (s) 13 and guide channel 14b, before the inlet connection parts 3a and the outlet connection parts 6, 7 also engage. This thread configuration therefore avoids double adjustments and the forces required to screw and unscrew can be further reduced.
    [00067] In the embodiment of Figures 22 to 23a, the end of the threaded segment 45 of the mixer 3, which faces the cartridge, does not reach up to the edge of the mixer housing on the side of the cooling chamber. As a result, a cylindrical section is created at the end of the mixer housing on the side of the cartridge, which does not include a thread. This section can be used to guide the mixer housing, in addition to the guide through the guide rib (s) 13 and the guide channel 14b inside the ring or flange-like edge 1b of the cartridge, on which the internal thread 44 is located.
    [00068] As an alternative to this, it is possible according to the invention to do without this additional guide, so that when the mixer is mounted on the double cartridge 1, the mixer is first guided exclusively and aligned by at least one guide rib 13 , which engages with the guide channel 14b.
    [00069] For this, the external thread 45 of the mixer housing can go upwards, up to the edge of the mixer housing on the side of the cartridge. This is shown in the modalities in Figures 24 and 25, with the mixer in Figure 24 having three threaded rod segments, which sometimes overlap, which in each case extend for approximately 120 °, while the mixer according with Figure 25 it has two threaded bar segments, which do not overlap, and which extend, in each case, approximately 180 °. According to the invention, in the mixers according to Figures 24 and 25, the contact between threads 44, 45, when screwing or unscrewing the mixer, as explained in relation to Figures 22 and 23a, can also occur with low friction, in each case, only one surface of the threads makes contact.
    [00070] Another modality is shown in Figure 26, whose structure corresponds, substantially, to the modality of Figure 21. However, in the cartridge in Figure 26, the internal ramp 46 in the transition section between the plate 1a, in which the outlet connection parts 6, 7 and the ring 1b or the flange that includes an internal thread 44 are omitted, so that the mixer, although it can be unlocked by this rotation of the mixer housing in relation to the cartridge, the mixer, however , is not lifted from the cartridge by continuous rotation. On the contrary, the mixer 3 needs to be pulled out of the cartridge by means of threads 44k, 45k, after the engagement with the cartridge is released. Figure 26 also shows the additional axial bars 48 on the inner side of ring 1b, which limit - together with bars 47 - the rotation of the mixer 3 in relation to the cartridge when the connection is released.
    [00071] Another locking plug 15 is shown in Figures 27 and 27a, which, in turn, has projections that lock outlet connection parts 6, 7 and is housed with a cylindrical section within the ring or collar 1b of the cartridge. To engage the locking plug 15 on the cartridge, hooks 49 are provided, which can be engaged behind the free ends of the threaded bar segments of the internal thread 44.
    [00072] In this way, the locking plug 15 can be engaged with the cartridge. To release this connection, the locking plug 15 is guided in relation to the cartridge, so that the hooks 49 are released from the threaded bar segments. At the same time, the free end of the hook 40 on the side of the cartridge can come into contact with the adjacent threaded bar segment (at the bottom of Figure 27a), so that, as a result of rotation, the locking plug 15 is also lifted from the cartridge.
    [00073] Figures 28 and 29 show another modality, which corresponds, substantially, to Figure 24, that is, the threads 44, 45 are, in each case, configured with threaded bar segments, which overlap in sections. Fundamentally, outlet connection parts 6, 7 of a cartridge can also protrude beyond the plate 1a, as indicated, for example, in Figures 28 and 29.
    [00074] Regardless of this, on the plate 1a, a guide ridge 14a may be formed, which facilitates the insertion of the guide rib 13 into the openings 14b.In the embodiment shown in Figures 28 and 29, this additional guide ridge 14a has two sections funnel-shaped, facing each other, on the sides of the guide openings 14b, which are connected with each other towards a curved section. In addition, the guide projection 14a can in this case be directly connected with outlet connection parts 6, 7 or be located a short distance from them.
    [00075] In addition, ribs can be seen on plate 1a in Figure 29, which are opposite the guide opening 14b. They prevent the mixer 3 from being mounted on the cartridge in the wrong direction.
    [00076] Due to the high pressure that is generated during distribution, the impermeability between the cartridge and the mixer is especially important in modern distribution systems (cartridge, mixer and distribution device to drive the pistons in the cartridge). According to the invention, this is also achieved, for example, in the modalities of Figures 28 and 29 by the fact that by a thread with several threads, a large relative axial movement between the mixer and the cartridge is generated during the process screwing. In this case, the mixer can be firmly pressed on the cartridge, so that, on the one hand, the inlet and outlet connection pieces are connected with each other in an airtight way, and, on the other hand, even inside the cartridge itself. mixer, particularly between the mixer housing 3c and the coupling section 3d, the impermeability is improved. In addition, the thread turns, which are preferably displaced by 120 °, and which overlap each other, one another, also absorb the forces that occur axially. However, this threaded connection also requires that the coupling section and the mixer housing are freely rotatable with respect to each other. This, in turn, has the effect of simplifying the alignment of the inlet and outlet connection parts, when assembling the mixer 3, first the guide rib engages with the guide channel and thus guides and aligns the mixer .
    [00077] Figures 30 and 31 show another aspect of a mixer 3 according to the invention, in which inlet connection parts 3a, 3b end in displaced planes in the mixing chamber formed in the mixer housing 3c. In other words, the inlet, for the mass that enters through the inlet connection piece 3b, is closer to the cartridge than the inlet for the mass that enters through the inlet connection piece 3a. In that case, an annular space is formed inside the mixer, which surrounds the mixer shaft 40, in which the mass entering through the inlet connection piece 3b can be captured before reaching the mixing chamber. This prevents an unsatisfactory mixing result at the beginning of the mixing process.
    [00078] The two planes, into which the masses enter, are separated from each other by a disc 50 on the mixer shaft 40, with openings 51 allowing the penetration of the incoming mass through the inlet connection part 3b. To make it more difficult for a mass of an input connection piece to arrive at a different one, when the mixer shaft 40 is stationary, ribs 51 are provided in the spaces between openings 51.
    [00079] Mixing blades 53 of the mixer shaft and the remaining mode, for example, of the connection section with a drive shaft, can be configured as shown in figures 12a to 12h.
