Description

TRANSMISSION DEVICE WITH TURNING DEVICE

The present invention relates to a discharge device for metering and discharging a component from at least one container, in particular a discharge device, which is suitable for mixing at least two components. Furthermore, the invention relates to a system for metering and discharging a component from at least one container.

STATE OF THE ART

In various technical fields and also medicine, it is necessary to have a product, such as a medical or pharmaceutical product, with a precise one

Dispensing dosage from its storage container. The products are often in syringes with a container for the product, which has an outlet, and with a

Piston rod, which closes the container with a stopper liquid-tight, supplied.

The manual pushing in of the piston rod causes the product to be discharged from the container through the outlet. With this discharge can not be precisely metered. It is therefore inaccurate and subject to errors. From US 4,479,781 is a

Dispensing device for metered dispensing of a product from a syringe known in which an accessory is used to allow accurate metering. The

Accessory has a handle with two forks, between which a syringe can be inserted. The piston rod is held against rotation by a fork and the

Syringe container can be rotated within the second fork relative to the piston rod. The product is discharged. Further, in many technical fields it is necessary to mix a mixture just before its application or administration. For this purpose, various discharge or mixing devices are known from the prior art, which have at least two containers with different components and the different components can simultaneously discharge from their respective container. Most of the containers are in the form of syringes or cartridges, which have an outlet at one end and at the other end, for example, a discharge piston. Inside the syringe, the respective component is received and can be ejected by advancing the Austragskolbens through the outlet. To the discharge piston, a piston rod can connect, with which the discharge piston can be advanced within the syringe. In order to be able to discharge and mix two components at the same time, the syringes are placed parallel to each other in a housing and the piston rods are simultaneously advanced by a drive mechanism in the respective syringe. The various components of the two syringes are ejected through the respective outlet and discharged eg into a common container. It is also possible to place on the discharge a Mischaufsatz on the two outlets, which has a mixing chamber with mixing elements for mixing the two components, wherein the mixed product is then discharged from the mixing attachment.

From WO2007 / 041266A1, for example, a delivery syringe with a plurality of containers for dispensing a mixture for dentistry is known. The dispensing syringe has a syringe body, in which two containers, each with a component are accommodated parallel to each other. Further, a piston rod is provided, which is divided into two, so that there are two parallel rods connected to each other, each projecting into a container of the syringe body. On the outer surface, the two rods have an external thread. On the syringe body, a rotary sleeve is provided at one end, which is rotatable about the syringe body, but is not axially displaceable. The rotary sleeve has an internal thread which cooperates with the external thread of the piston rod. In order to discharge the two components simultaneously from their containers, the rotary sleeve is rotated relative to the syringe body and the piston rod. The piston rod is due to their Threaded connection to the rotary sleeve in the axial direction inserted into the container and thus carries the component from the containers. Once the piston rod has been fully inserted into the containers, the dispensing syringe is discarded. Reuse of the syringe or replacement of individual components of the syringe is not provided.

WO2008 / 009143 shows a dispensing device for a multiple container, which has a housing for the multiple container, on which a rotating part is provided. Between the housing and the rotary member, a thread is provided to screw the housing into the rotary part can. For this purpose, the rotary member has two concentric sleeves, wherein the inner sleeve has an external thread. The inner circumference of the housing has an internal thread, which corresponds to the external thread of the inner sleeve of the rotary member. If the rotary member is rotated relative to the housing, the housing wall screwed between the two sleeves of the rotary member and the inner sleeve acts as Austragskolben on the piston rods of the two containers in the interior of the housing, so that their components are ejected simultaneously. Once the rotary part is completely screwed over the housing, the components are discharged and the dispenser is disposed of. It is not intended to use the dispenser a second time for other containers.

It is therefore an object of the present invention to provide a Austragsvoπichtung for discharging components from at least one container, which is reusable, can be adapted to specific discharge specifications, in particular Dosiervorgaben, suitable for the discharge of different types of containers, from a few components is composed, allows easy cleaning and sterilization and allows easy handling during discharge. In particular, it is an object of the invention to provide a system for discharging components from containers, which comprises a discharge device that can be used for various containers and is provided as a kind of accessory for the various component containers. PRESENTATION OF THE INVENTION

This object is achieved according to the present invention by a discharge device according to claim 1 and a system for discharging components from containers according to claim 12. Advantageous embodiments of the discharge and the discharge system will become apparent from the respective dependent claims.

A discharge device according to the present invention comprises at least one container which can receive a component in it and has outlet and a discharge element. Preferably, the discharge device comprises two or more containers, each receiving a component and each having an outlet and a discharge element. The containers are preferably designed in the manner of a syringe, which comprises a sleeve-shaped body with an outlet at one end and a piston or plug at the opposite end and a piston rod for advancing the piston. In principle, however, it is also possible to use other container shapes, such as ampoules or cartridges or even a flexible container in the manner of a bag. Further, the discharge device according to the present invention, a rotating device, which comprises a drive member and a rotary member, wherein upon rotation of the rotary member relative to the drive member, the drive member is movable in the axial direction relative to the rotary member and the discharge elements in the at least two containers for discharging the Drives components. For this purpose, the rotary device preferably has a threaded connection between the drive member and the rotary member. The threaded connection can preferably be provided directly between the drive member and the rotary member. However, it is also possible to provide the threaded connection between the drive member and rotary member via further threaded elements, such as in a transmission, possibly also with a transmission or reduction. A translation may be advantageous, for example, if, during the discharge of the components or during the mixing of the components, a particularly slow discharge is to be ensured. In an advantageous embodiment of the threaded connection is the drive member is provided as a threaded rod which cooperates with a thread on the rotary member. The threaded rod engages directly on the Austragselementen the container or acts indirectly on other components on the discharge elements.

According to the present invention, in the discharge device, a housing member is provided, on or in which the at least two containers, the drive member and the rotary member are arranged, wherein the container or at least one of the containers is removably attached to or in the housing member. In the case of a plurality of containers, these are arranged on or in the housing element such that their respective outlets and their discharge elements point in the same direction. For example, syringe-like containers can be arranged parallel next to one another. Advantageously, the plurality of containers are arranged triangular, square or annular. The containers can be completely absorbed by the housing element or only partially. protrude into the interior of the housing. Furthermore, it is also possible to accommodate the containers in a second housing element and to connect the second housing element to the first housing element. It is essential that the drive member can act on the Austragselemente the container. The drive member is therefore provided in the housing member such that it acts directly or indirectly on the discharge elements of the container.

It is an advantage of the discharge device according to the present invention that the rotating device with the housing element can be used several times for different containers. It is not necessary to dispose of the entire dispenser just because one or more containers are empty. The discharge device can therefore be manufactured inexpensively and the reused components can be manufactured with an increased quality, since the additional costs are worthwhile due to their reuse. It is particularly advantageous that various containers, for example, with different diameters or different lengths, can be used in the housing element. Furthermore, the dispensing device according to the invention enables the precise manual dosing of the components from the containers. In a preferred embodiment of the present invention, not only the containers may be detachably attached to or in the housing member, but also the drive member and / or the rotary member may be detachably provided on or in the housing member. Thus, it is possible to disassemble the Austragsvorrich- device according to the present invention in their only a few components and to clean and autoclave in a simple manner and thus provide them for reuse. Particularly preferably, the discharge device has no more than the following components: container, a housing element, a drive member and a rotary member. Of course, in addition to these components to the outlets of the container, a Austragskanüle, a mixing attachment or the like can be placed.

In one embodiment of the present invention, the threaded rod on a guide means which cooperates with a complementary guide means on the housing member such that the threaded rod are axially displaced to the housing member, but can be arranged rotationally fixed. For this purpose, the threaded rod is e.g. Flattened on two opposite sides in the longitudinal direction, so that form two parallel guide surfaces along the axis. Between these surfaces, the thread segments for the threaded connection are arranged with the rotary member. The housing element has as a complementary guide means to the guide surfaces on two mutually parallel parallel flanks whose distance corresponds to the thickness of the threaded rod between the guide surfaces. To insert the threaded rod into the housing element, it is pushed with its guide surfaces between the guide flanks. The threaded rod can thus be displaced in the axial direction between the guide flanks of the housing element, but is prevented from rotating relative to the housing element due to the abutment of the guide surfaces on the guide flanks.

The housing member receives the rotary member so that it is rotatable relative to the housing member, but is fixed in the axial direction. The rotary member is arranged on the housing such that a sufficient area protrudes from the housing or projects beyond the housing in order to be able to grip the rotary member and to be able to rotate relative to the housing element. In the case of a threaded rod with guide surfaces is the Rotary member arranged on the housing member such that the threaded rod can be inserted into the interior of the rotary member or can protrude. Preferably, the rotary member is sleeve-shaped and has on its inner circumference an internal thread, which corresponds to the external thread of the threaded rod.

For receiving the rotary member, the housing element may at least partially have around its circumference an annular groove. Preferably, the annular groove extends by approximately 180 ° on the circumference of the housing element. The annular groove can be provided outside in the peripheral surface or as a kind of blind groove on an inner circumferential surface. The rotary member has a matching flange to the annular groove, which is insertable into the annular groove. The flange is either to put over the outer circumference of the housing member into the annular groove into or introduce along the blind groove in an inner annular groove.

In order to assemble the rotary device of the discharge device according to the invention, the rotary member is first attached to the housing element in such a way that the internal thread comes to lie in the axial extension of the guide means of the housing element. Further, the drive member is inserted so far into the guide means of the housing member until it reaches the rotary member. It is introduced until the threads of the threaded connection can interlock. Subsequently, the rotary member is rotated relative to the housing member and the drive member such that the drive member is further inserted by means of the threaded connection in the rotary member, or screwed. The housing member with the inserted rotary member and drive member forms the rotating means in the form of an accessory for the container or containers to be able to discharge the components.

For a discharge of the components according to a desired dosage from the container or the plurality of containers, the containers are also arranged on the housing element. They are mounted in such a way that their discharge elements come to lie opposite the end of the drive member which protrudes from the rotary member. The containers are immovably held by the housing member in the axial direction. Advantageously, the containers are also arranged rotationally fixed, but this is not absolutely necessary for the function of the present invention. For this example can a holding recess may be provided in the housing element, in that a projection provided on the container can engage. The discharge elements of the containers, which are preferably designed as piston rods, can thereby protrude into the interior of the housing element, in particular also between its guide means. As a result, they come to rest against the drive member and can also be guided in the axial direction. Jamming of the Austragselemente during the feed by the drive member is thereby prevented.

For a discharge of the components from the container now the rotary member is rotated in the opposite direction, so that the drive member is pushed out of the interior of the rotary member and thereby by the guide means to drive member and

Housing element is guided in the axial direction and advanced. Through the feed it hits the output elements and pushes them simultaneously and with the same

Speed inside the containers before. The feed expels the components through the outlets.

The entire length of Austragsvoπichtung thus does not change during the discharge, making handling easy. A user only needs to insert the container or containers into a ready-to-use accessory rotating device and to rotate it to the region of the rotary member projecting beyond the housing element. The rotation can be done with a single hand or assisted with a second hand.

The discharge device according to the invention is particularly advantageous for individually present containers which can be used and exchanged independently of one another in the accessory turning device. Of course, however, double containers may also be used with e.g. a connected dispensing element acting on both containers.

In a further embodiment, the rotary member along its circumferential direction on its outer surface have a rotary scale and the housing member has a pointer which is opposite to the rotary scale. Upon rotation of the rotary member relative to Housing, can be specified with the pointer a rotational position on the rotary scale. The rotation scale can be given by simple lines, by numbers or by a color marker.

Furthermore, the discharge device may have a device for generating an acoustic or tactile signal upon rotation of the rotary member. For this purpose, e.g. to be provided on the housing member projecting in the direction of the rotary member flexible tongue or a flexible projection or attached thereto. On the rotary member, in turn, a projection may be provided, which deflects the flexible tongue upon rotation of the rotary member and releases again upon further rotation, so that the tongue e.g. strikes against a stop member, and thus generates a noise. In principle, it is possible to provide a plurality of projections on the rotary member or to attach a plurality of flexible tongues on the housing element. Further, the flexible tongues may also be disposed on the rotary member and the projections on the housing member. By such an acoustic device thus the number of rotations or partial rotations can be mediated by means of a sound. Furthermore, the device can also be used as a tactile signal generator. During the deflection of the flexible tongue, the rotation of the rotary element is slightly but noticeably more difficult. Once the flexible tongue is released, the rotation is relieved again. A user can thus also sense the number of rotations or partial rotations.

As already described, the housing element can be connected to a further housing element of the discharge device and be provided detachably from this. Another housing element may be advantageous, for example, in housing a plurality of containers. The further housing element can then be attached to the Drehzubehöreinrichtung to dispense the components from the plurality of containers simultaneously and in parallel according to a desired dosage.

Furthermore, it is also possible to form the housing element in several parts, wherein the housing parts are at least partially or in places separable from each other. Such a trained housing element may be provided, for example hinged, wherein the individual housing parts, for example, connected by a film hinge can stay. Furthermore, it is possible, for example, to snap together two individual housing parts via a snap-action mechanism, wherein the snap-action is designed to be detachable. A multi-piece housing member may facilitate the attachment of the containers or the drive member and the rotary member, but is more expensive to manufacture and requires additional handles in providing the rotator.

In another aspect of the present invention, a system for discharging and metering components from containers is provided. The system comprises at least one container which can accommodate a component and has an outlet and a discharge element, and a discharge device for driving the discharge element. The discharge means comprises a housing member having a drive member disposed therein or thereon and a rotary member disposed therein or thereon. The discharge device can be removed from the container or the container can be removed from the discharge device. Preferably, the system comprises at least two or more containers. The system thus consists of several containers and a discharge device, which can be attached to the containers as a kind of accessory device and removed again from these. In the assembled state of the discharge device and containers, the discharge system corresponds to a discharge device as previously described. It is advantageous for a user that the discharge device according to the system according to the invention is suitable for the discharge of various types of containers. The containers need only be inserted in the housing element of the discharge and can then be distributed by rotating the rotary member relative to the drive member by the rotary member acts on the discharge elements in the containers.

As described above, the rotary member is preferably rotatable and axially fixed to the housing element for this purpose. The drive member in turn is rotatably and axially movably received by the housing member. Between the drive member and the rotary member, a threaded connection is provided. The rotating device and the housing element can be designed for this purpose as already described. In an advantageous embodiment of the discharge system according to the invention, the rotating device comprises a set of rotary members, which consists of rotary members of different thread pitch. Furthermore, the rotary device has a set of drive links, which consists of drive members of different thread pitch. For each rotary member of a particular thread pitch, a drive member is provided with a complementary matching thread pitch. In order to assemble the discharge device of the system for a particular type of discharge, or for a particular container, a suitable pair of rotary member and drive member may be selected from the set of rotary members and the set of drive members in accordance with the requirements for discharge. For example, if a slow discharge from the containers are provided, a pair of links with a low pitch can be selected. If a quick discharge is required, a pair of links with a large thread pitch is selected. The selected rotary member and drive member of the link pair is then placed on or in the housing member to form with this the discharge device, or the Zubehöreinrichtung.

In principle, it is of course also possible to provide a set of different housing elements, which has a matching guide for the drive members of the set of drive links and a matching receptacle for the rotary members of the set of rotary members, but which has different container receptacles for receiving containers of different types ,

The Austragssy system is thus constructed like a box and depending on the requirements of a discharge or the specifications by a particular container, a suitable discharge device can be put together. It is advantageous that the discharge device consists of only a few components and can be assembled and disassembled in a simple manner.

The present invention forms inter alia a further development of the dispensing device according to the Swiss Patent Application No. 0038/08 of the applicant, whose Priority is claimed and to which reference is made to the design of individual features of the discharge.

The discharge device according to the present invention has, in the form of the housing element, a housing for receiving multiple components and, in the form of the rotary element, a rotary part with a thread. The housing element and the rotary member cooperate such that by rotating the rotary member acting on the piston in the form of Austragselemente multiple tappets in the form of the drive member is continuously displaceable in the discharge relative to the housing element. The drive member according to the present invention may also be designed as a multi-poppet, as shown, for example, in Figure 2 of the priority application. The housing element is designed such that it can accommodate two adjacent containers. The thrust of the rotary member can be transmitted directly to the drive member in the form of the multiple plunger without changing the overall length of the discharge device.

The inventive housing element can accommodate a multiple cartridge having at least two adjacent containers. According to the present invention, the multiple cartridge is detachably or interchangeably provided on the housing member. The rotary member in the form of the rotary member according to the present invention has an internal thread which is in operative connection with a corresponding external thread on the drive member in the form of the double plunger. For this purpose, instead of a threaded surface extending over the entire length of the drive member, the drive member may have a feed flange which is provided with the external thread on its outer region. The connection between the internal thread of the rotary member and the external thread of the feed flange causes a rotation of the rotary member, a feed of the drive member in the axial direction. The feed flange can be guided to prevent rotation of the drive member between the guide flanks on the housing element, which form a kind of guide slot, secured against rotation.

According to the invention, the housing element or a second housing element which is detachably connected to the first housing element, the multiple cartridge in itself take up. The housing member with the multiple cartridge may then have an outlet end having a bayonet-claw reinforcement. This bayonet claw reinforcement can support a bayonet claw, which is provided at the outlets of the multiple cartridge.

The housing element, in which the multiple cartridge is housed, may be formed at least partially transparent in the longitudinal direction of the multiple cartridge, so that through the transparent area the discharge element is visible in the interior of the container and can serve as a level indicator for the level in the container. For this purpose, a graduation can be provided on the housing element which indicates the already discharged volume or the volume still provided in the container.

Furthermore, the discharge device according to the present invention may comprise a means which audibly indicates the rotation of the rotary member by a certain angle of rotation, as shown in Figure 6 and the associated description of the priority document.

FIG. 1 shows an exploded view of a discharge device according to the present invention. In this embodiment, the discharge device comprises two containers 1 each having an outlet 2 and a discharge element in the form of a piston rod 3. In another embodiment according to FIG. 8, the discharge device has only one container. The discharge device comprises a rotating device with a drive member in the form of a threaded rod 4 and a rotary member 5 and a housing element 6. The housing member 6 has at one end a Behälteraufhahme 7 for releasably receiving the container 1 and at the other end a rotary member receptacle 8 for releasably receiving the Turning on. The housing member 6 is elongated, with the length of the feed path, which is required in order to discharge the full amount of a component which is housed in the container. The housing element 6 is cup-shaped or sleeve-shaped. For the passage of the piston rod 3 through the housing element, this has a passage 9 in the longitudinal direction with a lateral opening 26. In order to form the container receptacle 7, two opposing slots 10 running perpendicular to the longitudinal axis are provided in the housing element 6 in the peripheral wall of the housing element 6. The slots are open to one side of the housing member and closed to the opposite side of the housing member. Of the Container 1 has, at its end opposite the outlet 2, two wings 11 projecting perpendicular to the axis of the container. The wings 11 of the container and the slots 10 of the housing member 6 are dimensioned such that the wings 11 can be inserted at the open side into the slots 10 and thus the container 1 is held relative to the housing member 6 in the axial direction. The piston rod 3 comes to lie in the passage 9.

For the rotary member receptacle 8, the housing element 6 has at the other end a blind groove 12 which has an insertion opening on the side of the housing element 6. On the opposite side, the groove is closed and formed as an annular groove. The rotary member 5 is formed substantially sleeve-shaped and has at one end a circumferential radially projecting flange 13. The blind groove 12 of the housing member 6 and the flange 13 of the rotary member 5 are dimensioned such that the flange 13 can be inserted into the blind groove 12 and is rotatably received by this. As a result, the rotary member 5 is axially fixed to the housing member 6.

The threaded rod 4 is formed as a flattened rod with two parallel opposing guide surfaces 14. At its end opposite the containers 1, the threaded rod 4 has a broadening plate 15, the surface of which is sufficiently large to be able to grasp both adjacent piston rods 3 of the two containers 1. The housing element 6 has, in a passage region, two passage flanks 16, which form a passage opening for the threaded rod 4. The flanks 16 run parallel to each other at a distance which corresponds to the thickness of the threaded rod 4 between the guide surfaces 14. If the threaded rod 4 is pushed through the opening between the two flanks 16, the guide surfaces 14 and the flanks 16 come to lie against one another and the threaded rod 4 is secured against rotation relative to the housing element 6.

The rotary member 5 has an internal thread 17 in its inner circumference. The internal thread may extend over the entire length of the sleeve-like interior or be provided only in an initial region. The length of the rotary member 5 is on the

Length of the threaded rod 4 tuned. The threaded rod 4 has at her Outer circumference between the guide surfaces 14 on an external thread 18, which corresponds to the internal thread of the rotary member 5.

The rotary member 5 has, in a drum-like region of its outer circumference, a rotary scale 19 which assigns a distributed or metered component quantity to a rotary position of the rotary member. On the housing element 6, a pointer 20 is arranged on the opposite side of the rotary member 5, which indicates a rotational position of the rotary member relative to the housing element 6.

At its opposite end of the housing member 6, the rotary member 5 on handle wing 21, to which the rotary member 5 can be manually held in order to rotate it relative to the housing member 6 can.

At the outlet end of the containers 1, a mixing attachment 22 is provided, which has two inlet channels 23, which converge to form a common outlet channel 24.

FIG. 2 shows the discharge device from FIG. 1 in the assembled state. The containers 1 are inserted with their wings 11 into the slots 10 of the housing element 6, the piston rods 3 coming to lie in the laterally opened passage 9. The mixing attachment 22 is placed with the two outlet channels 23 on each outlet 2 of the container 1. The rotary member 5 is inserted laterally with its flange 13 in the blind groove 12. The rotary scale 19 of the rotary member 5 comes to rest against the pointer 20 of the housing element 6. The threaded rod 4 is performed with its guide surfaces 14 between the flanks 16 of the housing member 6 and protrudes through the passage 9 out of the end of the housing member 6 and into the rotary member 5 inside. In this case, the internal thread 17 of the rotary member 5 and the external thread 18 of the threaded rod 4 engage each other.

To assemble the discharge device according to the present invention, the rotary member 5 is first inserted with the flange 13 in the blind groove 12 of the housing member 6. Subsequently, the threaded rod 4 between the edges 16 of the Housing member 6 is pushed through until it comes to rest at the beginning of the internal thread 17 of the rotary member 5. The rotary member 5 is rotated within the blind groove 12 until the internal thread 17 engages in the external thread 18 of the threaded rod 4 and the threaded rod 4 holds securely. By further rotation of the rotary member, the threaded rod 4 is rotated in the rotary member, so that in the passage 9 space for the piston rods 3 of the container 1 is free. In this assembled state, the housing member 6, the rotary member 5 and the threaded rod 4 form a discharge, or rotating device, the z. B. can be supplied as an accessory with the containers 1. Finally, the containers 1 are inserted with their wings 11 in the slots 10 of the housing member 6, so that the piston rods 3 of the widening plate 15 of the threaded rod 4 are opposite.

Figure 3 shows a sectional view through a discharge device according to the present invention, in which the discharge device is in an initial state. The containers 1 were inserted parallel to one another in the slot 10 of the housing element 6. Inside the container, a first component 25a in the first container and a second component 25b in the second container can be seen. The mixing attachment 24 was placed on the two outlets 2 of the container 1, so that there is a fluid connection between the containers and the mixing attachment. The piston rods 3 are inserted at the outlet opposite end of the container 1 in this liquid-tight. The inserted into the container end of the piston rod thus forms a plug which closes tightly with the inner peripheral wall of the container but is displaceable. The piston rods 3 come to rest in the passage 9 of the housing element 6. At the opposite end of the container, the rotary member 5 is inserted into the blind groove 12 of the housing member 6. In this case, the flange 13 comes to lie in the blind groove 12 and serves as a rotary guide for the rotary member 5. The threaded rod 4 is guided through the passage 9 of the housing member 6 and screwed into the rotary member 5. It can be seen how the threaded rod 4 is received with almost its entire length in the interior of the sleeve-like rotary member 5. The piston rods 3 come to rest with their end opposite the container to the widening plate 15 of the threaded rod 4. The threaded rod 4 is guided by the housing element 6 by the guide means in the form of flanks 16 axially movable but rotationally fixed, so that upon rotation of the rotary member in the blind groove 12 of the housing member, the rotational movement due to the threaded connection, which is formed by the internal thread 17 on the rotary member 5 and the external thread 18 on the threaded rod 4 in a feed movement of the threaded rod 4, so that the broadening plate 15 to the End surfaces of the piston rods 3 abuts.

It can be seen in FIG. 3 that the passage 9 of the housing element 6 has a lateral slot opening 26 extending in the longitudinal direction. The slot opening extends up to a wall disposed in the housing element 6, which extends transversely to the longitudinal axis of the housing member and in which the flanks 16 are cut and thus further the passage 9. The blind groove 12 is also open on one side of the housing member and closed on the opposite side, in which it forms the annular groove for the flange 13, which guides the rotary member 5 in one rotation.

In Figure 4, the discharge device is shown in a state in which the components 25a and 25b are ejected from the containers 1. For this purpose, the rotary member 5 has been rotated relative to the housing element 6, so that the threaded rod 4 advances relative to the housing member 6 and the rotary member 5 in the axial direction of the container 1 and the piston rods 3 out. The feed force of the threaded rod 4 is transmitted to the piston rods 3, which are advanced within the container 1 in the direction of the outlets 2 and thus pushes the components through the outlets 2 in the channels 23, 24 of the mixing attachment 22. The container 1 are held securely in the housing element 6, since their wings 11 abut in the feed direction on the flanks of the slots 10. The threaded rod 1 is displaced within the passage 9 of the housing member 6 between the flanks 16 therethrough.

FIG. 5 shows a cross section through the discharge device according to the invention, which runs through the line along the flange 13 of the bag groove 12 of the housing element 6. In this embodiment, the flange 13 is provided on its outer circumference with a circumferential groove. This results in a kind of double-walled flange, wherein the groove is located between the opposite inner sides of the walls and the flange with the outer sides of the walls fit into the annular groove of the Sacknut 12 can be used. In the sectional view it can be seen that at the point of the blind groove 12 of the housing member 6 at a position at which the blind groove 12 forms the semicircular annular groove in the peripheral wall, an acoustic element 27 is inserted. The acoustic element 27 can be snapped with a snap connection into an opening in the housing element 6. The acoustic element 27 has an elastically deflectable blade or tongue 28. The tongue protrudes in the radial direction to the central axis of the rotary member 5. Between the two walls of the flange 13, a radially outwardly projecting projection 29 is provided on the peripheral surface. The projection 29 protrudes so far that it deflects the tongue 28 of the acoustic element 27 upon rotation of the rotary member 5. If the rotary member and thus the projection 29 further rotated, the tongue 28 snaps over the projection 29 and generates a clicking sound. It is also possible to provide next to the tongue 28 a stop wall against which the tongue 28 strikes when snapping back and thus generates a noise. Of course, a plurality of projections 29 may be provided on the circumference of the flange inner surface, and a plurality of acoustic elements 27 may be provided on the housing member 6.

Next, from Figure 5, the rotary dial 19 on the rotary member 5 and the pointer 20 on the housing element 6 can be seen. The rotary scale 19 consists of volume data in tenths of a milliliter increments. Upon rotation of the rotary member 5, the rotary dial 19 is rotated relative to the pointer 6 and thus outputs the spilled amount of the components from the containers.

FIGS. 6a and 6b show a front view of the section from FIG. 5. In FIG. 6a, the projection 29 on the flange 13 of the rotary member 5 comes straight on the tongue 28 of FIG

Acoustic elements 27 to lie in the circumference of the housing member 6. In FIG

Rotary member 5 and thus also the flange 13 with the projection 29 is rotated clockwise relative to the housing member 6, so that the projection 29, the tongue 28 of the

Acoustic elements 27 deflects. As soon as the rotary member is rotated further in a clockwise direction, the tongue 28 slips off the projection 29 and generates an acoustic signal. As long as the

Projection 29 on the tongue 28 engages the rotational movement of the rotary member 5 slowed slightly but noticeably. This braking effect gives a tactile signal for a specific rotational position.

FIG. 7 shows a further embodiment of a discharge device according to the present invention. From a system according to the invention for discharging and metering components from containers, two containers 101 and 101 'were selected. The containers 101 and 101 'are formed sleeve-shaped, wherein the container IUI ^{1 has} a smaller diameter than the container 101. The containers 101 and 101 'have the same length.
