Description

The The invention relates to a container for storing and dispensing of at least two components, in particular by means of a dispensing gun or similar. In this case, the container has at least two Chambers for receiving the components, a piston device for simultaneous ejection of the components from the chambers and an openable Sealing device for sealing the chambers on.

From the WO 2005/01 61 70 A2 Such a container in the form of a double syringe is known. Also in the EP 1 426 017 A2 a similar container is disclosed. These containers are equipped for each chamber in which components are accommodated with a piston of its own associated piston rod, which protrude from the rear of the container. This entails the risk that the containers are opened and emptied by improper handling during transport or storage by unintentionally advancing the piston rods. The handling of the various piston rods is sometimes perceived as cumbersome. Furthermore, a mixer or the like applicator must sometimes be placed in several separate working steps and / or the container must be opened.

Also from the EP 1 679 126 A1 as well as from the EP 0 624 403 B1 Each container for storing and dispensing of two components are known in which a rear projecting from the container piston rod is provided. In these containers, a user must also attach a mixer or applicator to the container after opening the container before the components housed therein can be discharged.

Further, TAH Indusries, Inc., Robbinsville, USA calls 'u-TAH ^™ nano' a container having two chambers arranged coaxially with one another and essentially one behind the other, which can be emptied by means of a pot-type transfer flask. This container is supplied with a cap that must be removed before the first use, if necessary to attach a separate mixer or the like. Applicator to the container. The container 'u-TAH nano ^TM' includes a holding portion which is suitable for connection to a dispensing gun, which is marketed under the name 'Centrox ^®' of the Centrix, Inc. Shelton, USA. Such a pistol is also in the EP 1 256 389 A2 shown.

such Dispensing guns are as hand dispensers for so-called preloaded tips (PLT) for dispensing 1-component dental composites present in almost every dental practice. From an economic perspective It is therefore desirable to use these existing dispensers or pistols for as many dental material groups as possible and in particular also for 2-component systems. The present invention sets itself the task of a container of the type mentioned above, with a high level of user-friendliness at the same time enables safe storage of the components.

These Essentially, a task with the container Characteristics of claim 1 solved. The invention draws in particular by the combination of a container with a pre-assembled mixer, one without Disassembly of the mixer openable sealing device and a transport lock that prevents the container unintentionally opened during transport or storage.

The latter function is achieved in that, in a holding portion of the container facing away from the mixer, a piston rod associated with the piston rod is slidably received so that the piston rod does not protrude appreciably from the holding portion of the container. In other words, the piston rod terminates substantially flush with the end face of the holding section facing away from the mixer. The flush closing of the piston rod with the end face of the holding section of the container facing away from the mixer is understood to mean not only an exactly flush but also that the piston rod extends by a few millimeters, preferably not more than about 1 to about 2 mm, over the front side the holding section protrudes. In this embodiment, the container is also suitable for use with a dispensing gun or a dispenser of the type mentioned above, for example with a 'Centrix ^® ' pistol. For the function of the transport lock, however, it is irrelevant whether the piston rod is slightly offset from the end face of the holding section facing away from the mixer. At most, this limits the possibilities of completely emptying the container.

If the mixer according to the invention is preassembled on or on the container, the container can be used immediately without time-consuming assembly steps. Under a pre-assembled mixer is a mixer, in particular a static mixer, understood, which is already provided in the delivery state of the container in such a position on or on the container, which is also suitable for the application of the components substantially. This does not exclude that the mixer or a mixing tube or a dispensing tube of the mixer before the first Be use of the container may need to be slightly rotated and / or moved relative to the container to open the container. However, it is preferred if the mixer is preassembled on or on the container such that the mixer is already in the end position suitable for dispensing the components.

The Use of the container is inventively characterized further simplifies that the sealing device without disassembly of the mixer is openable. So it does not have to be the first pre-assembled mixers are removed from the container, to open the sealing device. Rather, it will Preferably, when the sealing device is designed so that It allows an intuitive opening of the container. Under an intuitive opening the container will doing a release of a flow connection between understood the chambers and the mixer, which without separate opening steps in particular alone by advancing the piston rod or the piston device takes place. So is after a particularly preferred Embodiment of the invention, the sealing device such that upon actuation of the piston device, in particular depending on the internal pressure in the Chambers, self-acting, d. H. without additional operation by the user, the flow connection between the chambers and releases the mixer. This includes, for example a defined bursting of the sealing device, an elastic compliant and the flow connection releasing sealing device and / or the displacement of a sealing element, the mixer or a delivery tube of the mixer.

A particularly good sealing of the container at the same time Easy opening can be achieved by at least one of the chambers has a discharge opening, the one Closing piston is assigned as a sealing device, the off a position closing the discharge opening by the pressure of the auszubringenden component in a discharge opening opening Position is movable.

This can in particular take place in that at least one of the chambers has a preferably channel-like discharge opening which has a first area with a reduced cross-sectional area and a further area with an extended cross-sectional area and which for closing and releasing the discharge opening a displaceable from the first area into the second area Closing piston is assigned as sealing means with an at least partially congruent to the first region contour, so that the closure piston releases in a shifted from the first region in the second region position a flow connection between the chambers and the mixer. In other words, the closure piston sealingly closes the first region of the discharge opening during transport and storage of the container. Before or during the first use, the closure piston is then displaced from the first region into the second region, so that the components can flow through the closure piston and / or around it into the mixer. The basic operation of opening a container is in the DE 102 54 409 A1 described.

A Reduction of the cross-sectional area in the first area the discharge opening can take place, for example, by that in the discharge opening radially inwardly projecting projections are provided. Alternatively or in addition to this may also a central pin or web, for example, an annular Defined free space to be provided in the discharge opening. The closure piston is then corresponding with lateral recesses and / or a central opening provided.

alternative For this purpose, it is also possible that the sealing device and the mixer are formed such that the sealing device relative to a rotation and / or displacement movement of the mixer to the chambers automatically a flow connection between the chambers and the mixer releases. This can be, for example be effected in that one or more discharge openings of the Chambers in the preassembled state of the mixer not with appropriate Inlet openings of the mixer are aligned.

It is preferred when the mixer is releasably attached to the container and / or at least one discharge opening of the chambers attached is. However, the container may also be for single use have a mixer that is not detachable or even in one piece on the container and / or a discharge opening the chambers is attached. In this case, the mixer is a preferably static or dynamic mixer or an applicator, in the components are mixed together before exiting.

On the side facing away from the mixer of the container, a holding portion is provided, in which a piston rod is guided displaceably. This holding section has a first area with a smaller outer diameter and an adjoining second area facing away from the mixer with a larger outer diameter. In this case, the first region in the axial direction of the container may be longer than the second region, which may be formed, for example, approximately flange-like. This second area with increased outside diameter supports the transport function securing the container according to the invention by preventing unintentional opening of the container, if it experiences a shock in the direction of feed of the piston rod during transport or storage. The flush closing of the piston rod with the end face of the second portion of the holding portion, the piston rod can not be pushed further into the container, which could lead to an opening of the container.

A particularly expedient arrangement of the chambers in the container is the coaxial provision of the chambers, so that one chamber encompasses the other chamber. The chambers can However, also be arranged one behind the other and / or next to each other.

Independently Of the aforementioned features is an essential aspect the present invention in that the piston means of the Container has a transfer ram, which one guided in the holding portion of the container Piston rod and associated operating sections for Having the components from the chambers. The operating sections can each be displaced with one in the chambers Cooperate piston. According to a particularly preferred embodiment invention, the transfer ram is designed in such a way that that each chamber of the container is a separate from the piston rod in the direction of the mixer projecting operating portion assigned. The handling of the invention Container is further facilitated by the Advance the one piston rod of the transfer ram simultaneously advanced two or more operating sections can be so that all chambers emptied simultaneously can be. This also simplifies the use of the inventive container in one Applicator, such as a dispensing gun, with only a sliding pestle. In training This inventive concept, the piston rod and the operating portions of the transfer ram be integrally formed with each other.

alternative or in addition to the aforementioned features, the inventive container an opaque Have housing in which the chambers for receiving the Components are provided. Thus, the container is particularly suitable also for storage-stable storage of photosensitive components. To allow a level control of the components In this case, a window is preferably provided in the housing, which is arranged and formed such that through the window one of the piston device associated marking element visible is. The position of the marker visible through the window thus shows the level of the components in the container , wherein the storage stability of the components by the Window is not affected if its dimensions are chosen so that this exclusively on the separated by the delivery piston of the chambers, the mixer opposite side of the housing be found. The window and / or The marking element may additionally have a scaling and / or grid division be assigned to, for example, the dosage to facilitate.

To a preferred embodiment of the invention is the Mixer a static mixer with a mixing element for deflecting the components to be mixed and with a surrounding (dispensing) tube is. In this case, they are preferably integral with the housing of the container projecting in the axial direction of the mixer Provided spring arms, the radially inwardly projecting ribs, for example Latch hooks or protrusions, with which the tube can be locked on the housing. In this way, the Mixer or (dispensing) tube particularly simple be preassembled on the housing of the container, so before using the container for the first time the mixer not only with additional effort on the container must be attached.

In principle, the mixing element can be designed as a mixer helix or, for example, as a rectangular labyrinth element, wherein the (dispensing) tube can then be designed correspondingly with an angular cross section. In this case, the mixing element can be connected in one piece or in another suitable manner to the housing of the container or be assigned to the (dispensing) tube. For this purpose, the mixing element can also be connected to the (dispensing) tube, for example by latching, in order to assemble or disassemble the mixer as a unit. Examples of the formation of a mixing element are in the US 4,538,920 , of the EP 1 550 512 , of the WO 2004/052519 , of the EP 1 426 099 , of the WO 2006/039827 , of the EP 1 029 588 , of the EP 0 749 776 , of the EP 1 588 757 and the EP 0 815 929 described.

The opening of the container can be made particularly simple, that the mixer has a mixing element for deflecting the components to be mixed and a relative to the mixing element in the axial direction slidable tube, which is associated with a sealing device for sealing the chambers. This sealing device can be formed for example by plug-like closure piston, which are inserted into Ausbringöffnungen or channels of the chambers when the container is closed. To open the chambers, these closure piston can be by a relative movement of the tube to the Pull the mixing element out of the discharge openings or channels so that a flow connection between the chambers and the mixer is released. For this purpose, the closure piston can be integrally formed with the (dispensing) tube or attached thereto. In other words, to open the container according to the invention, only a relative movement between the tube and the housing or the mixing element must take place, for example, the tube of the housing and the mixing element in the discharge direction or advanced by the pressure of the components. In this case, either the engagement of a closure piston or pin with a sealing collar or the like. Of the tube can be disengaged by the relative movement or the closure piston or pin stops, while the sealing collar or the like. Of the tube is moved away. The released here channel does not have to run in the axial direction, but can also laterally, ie, for example, in the radial direction, run.

The The invention further relates to a combination of a container of the type described above and a dispensing device therefor. In this case, the dispensing device has a receptacle at least for the holding portion of the container and a relative to the container slidable plunger whose outer diameter less than or equal to the piston rod of the container is. The movable plunger can thus in the Retaining portion and thereby the piston rod of the transfer ram advance. The dispenser can be considered a manual and / or motor-operated dispensing pistol formed be or be designed for example as a syringe. Preferably is the applicator for multiple use suitable while the container is a disposable container or also a refillable container can be.

In the 1 to 6 is a trained as a mini-cartridge container 1 shown. The mini-cartridge is in turn with an inside and outside substantially cylindrical housing 2 and a lid closing off to the rear 3 formed, which can be latched onto the housing. Within the housing are two in cross section each approximately semicircular chambers 4a and 4b educated. About a piston rod assembly 15 , which partly through the on the housing 2 latched lid 3 extends and partially into the two chambers 4a . 4b protrudes, the volume of the chambers can be defined defined reduced.

On the lid 3 opposite end face of the chambers 4a . 4b is a coupling device 6 with a locking ring 7 for releasably securing a mixer 8th intended. Here is the locking ring 7 firmly on the container 1 latched and can relative to the container 1 between a coupling device 6 for the assembly or disassembly of the mixer 8th releasing and one the coupling device 6 blocking position in which the mixer 8th firmly on the container 1 is locked, as turned in the DE 10 2007 044 983 is explained in more detail.

The mixer 8th is in the illustrated embodiment as a Ausbringröhrchen 8a with a mixer helix 8b , ie formed as a static mixer. In the in 1 shown delivery condition of the container 1 is the mixer 8th already so on the container 1 pre-assembled so that the container can be used without further assembly steps.

The two adjoining chambers 4a . 4b each have a discharge opening 9a . 9b on that in a common Ausbringstutzen 10 open, which is approximately oval in cross-section in the illustrated embodiment. Accordingly, the mixer 8th provided with an inlet opening, which is also designed substantially in an oval, to the Ausbringstutzen 10 to be plugged in. The inlet opening is divided by a separating element into two sections, so that the from the chambers 4a . 4b discharged components, as explained in more detail below, separated from each other up to the mixer helix 8b of the mixer can be performed.

In which also in 3 delivery status shown are the two chambers 4a . 4b through a closing piston 11 closed, the two of a transverse wall to the rear, ie from the mixer 8th away, has projecting closure blocks whose outer contour to the inner contour of the discharge openings 9a . 9b is adjusted. In the illustration after 4 and 5 the locking blocks protrude into the discharge openings 9a . 9b and close it. Between the two shutter blocks, a gap-like space is formed, which corresponds to the rectangular contour of a partition 12 adjusted within the Ausbringstutzens 10 between the two discharge openings 9a . 9b is provided. The closing piston 11 can thus on the partition 12 led out of the in 5 shown closed position and in the in 6 shown opened position axially forward in the Ausbringstutzen 10 be moved, causing the two discharge openings 9a . 9b be released. The components can thus leave the chambers 4a . 4b through the discharge openings 9a . 9b and on the closure piston 11 over in the Ausbringstutzen 10 and in the mixer 8th stream. The discharge openings 9a . 9b thus form one through the closure piston 11 lockable area with reduced cross-sectional area, while the subsequent Ausbringstutzen 10 forms an area with increased cross-sectional area for receiving the closure piston in the open position of the sealing device.

To move the shutter piston 11 on the partition 12 is possible in the transverse wall of the closure piston 11 provided a vent and adjacent to the partition 12 in the closed state receiving space are also semicircular venting channels formed in the closure blocks. This ensures that the closure piston 11 put and on the partition 12 can be moved. On the opposite side of the two shutter blocks are on the shutter piston 11 Projections formed with the inlet opening of the mixer 8th interact so that the out of the chambers 4a . 4b discharged components separated from each other to the mixer helix 8b of the mixer 8th be directed.

The lid 3 of the container 1 is with a central in the illustrated embodiment holding portion 13 provided on the mixer 8th projected away from the container side. In this case, the holding portion has a first, approximately cylindrical region 13a and one to the mixer 8th remote, second area 13b on top of the first area 13a has a flange-like enlarged outer diameter. The holding section 13 is thus suitable for fastening the container in a dispensing gun after the EP 1 256 389 A2 ,

The holding section 13 is provided with a through hole in which a piston rod 14 a transfer ram 15 so slidably guided is that the piston rod 14 in the in the 1 . 3 and 4 As shown delivery state flush with the end face of the second area 13b concludes. The transfer ram 15 has two operating sections 16 on, each one chamber 4a . 4b assigned. The two spaced apart operating sections 16 sticking towards the mixer 8th from the piston rod 14 away into the chambers into which delivery piston 17 are slidably received. The transfer ram 15 causes the dispensing pistons 17 both chambers 4a . 4b be advanced simultaneously when the piston rod 14 in the passage opening of the holding portion 13 is pushed.

The 7 to 9 show a further embodiment of a container according to the invention, the two chambers 4a . 4b has, which are arranged one behind the other seen substantially in the axial direction. The first chamber 4a is doing by a sectionally cylindrical piston 18 and a Ausbringeinsatz 19 educated. The second chamber 4b is essentially through the case 2 the container itself, in which also the cylindrical piston 18 slidably guided, and a piston 20 limited, the application of the application 19 includes annular.

The discharge openings of the two chambers 4a . 4b lead into a common Ausbringstutzen 10 which forms a common discharge opening for both components. In the in the 8th and 9 lower area of the Ausbringstutzens 10 protrudes a sleeve-like tip of Ausbringeinsatzes 19 and thus reduces the cross-sectional area of the Ausbringstutzens 10 , In this area is a ring-like closure piston 11 provided, which in the position after 8th the discharge opening of the chamber 4b closing on the top of the Ausbringeinsatzes 19 sitting.

To open the container 1 can the shutter piston 11 within the dispensing nozzle 10 by the pressure of the in the chamber 4b contained component in the axial direction forward, ie on the mixer 8th to, can be moved to thereby both Ausbringöffnungen the chambers 4a and 4b release. As a result, the components can move together through the central opening in the annular closure piston to the mixer 8th stream. The mixer 8th is in this embodiment as previously described by means of a coupling device 6 and a locking ring 7 on the container 1 attached.

To discharge the components contained in the chambers of the cylindrical piston 18 towards the mixer 8th advanced. As a result, on the one hand reduces the volume in the chamber 4a so that the component received in this through the Ausbringeinsatz 19 to the Ausbringstutzen 10 is conveyed while simultaneously an axially front end face of the cylindrical piston 18 the piston 20 advances, so that also the volume of the chamber 4b reduced and taken in this component also to the Ausbringstutzen 10 and the mixer is promoted.

How out 8th and 9 shows, is the piston 20 opposite the outer cylindrical housing wall 2 the two chambers sealed by a sealing ring. In the same way is the Ausbringeinsatz 19 by a sealing ring opposite the cylindrical piston 18 sealed.

One of the previously described embodiment in the construction of the container similar embodiment is in the 10 to 12 shown. Here, the discharge openings of the two again open successively arranged chambers 4a . 4b but not in a common Ausbringstutzen 10 but there are two separate channel-like discharge openings 9a . 9b provided, each by separate annular closure piston 11 are closed. These locking plungers sit in the in the 11 and 12 shown closed state on pin-like projections 21 in the discharge openings 9a . 9b and may be due to the pressure of the components when deployed towards the mixer 8th from the projections 21 be moved away, so that the components through the central openings of the respective closure piston 11 can flow through it.

Due to the central arrangement of Ausbringeinsatzes 19 results in an eccentric arrangement of the discharge opening 9b for those in the chamber 4b on taken component. The mixer is also the same 8th placed eccentrically on the two chambers. In the same way is the coupling arrangement 6 for detachable connection of the mixer 8th arranged off-center.

Another embodiment of the invention is in the 13 to 15 represented, wherein the basic structure of the container according to the 1 to 6 equivalent. In the case 2 which is made of an opaque material in this embodiment is in the mixer 8th facing away, rear area a window 22 provided, which extends in the axial direction of the container. The window 22 is a marker 23 For example, a colored dot or protrusion on the transfer ram 15 assigned so that the marking element 23 by the window 22 is visible from the outside. Will now the transfer ram 15 for dispensing the components in the container 1 shifted, the position of the marking element changes 23 in the window 22 and thus allows monitoring of the level of the container. This is the window 22 provided with a scaling.

Since the chambers in which the photosensitive components are accommodated, for example, toward the window 22 through the delivery piston 17 sealed, the storage stability of the components through the window 22 not impaired.

To the marking element 23 over the entire displacement path of the transfer ram 15 in the window 22 to be able to see is the attachment of the lid 3 on the housing 2 compared to the embodiments according to the 1 to 12 modified so that the lid 3 the housing does not surround, but can be inserted into this and locked there.

The mixer 8th is with an additional application tube 8c provided that applying the from the mixer 8th exiting mixture, for example, facilitates dental applications.

The syringe-like spreading of the components out of the container 1 by means of a pestle 24 is particularly easy when the lid 3 as in the embodiment of the 16 and 17 shown a flange-like edge 25 having. The pestle 24 and the piston rod 14 have contours adapted to each other, so that the piston rod 14 and the pestle 24 together in the sleeve-like guide portion of the lid 3 can be performed. The pestle 24 relies for dispensing the components of the piston rod 14 embracing on one of the operating sections 16 connecting wall of the transfer ram 15 from.

The attachment of the mixer 8th on the housing 2 takes place in the illustrated embodiments by means of a coupling device 6 , the two spring arms 26 which is integral with the housing 2 are formed and next to the Ausbringstutzen 10 or next to the discharge openings 9a . 9b in the discharge direction of a front side of the housing 2 protrude. At the spring arms 26 are radially inwardly projecting ribs 27 provided as locking projections, the corresponding attack surfaces of the Ausbringröhrchens 8a can reach behind this on the case 2 to fix. About the locking ring 7 can the spring arms 26 to the delivery tube 8a defined to be applied or spread to the delivery tube 8a of the mixer 8th to lock or release.

Alternatively to the in the 1 to 17 the embodiment shown, the spring arms 26 also be designed and arranged so that the Ausbringröhrchen 8a even without the locking ring 7 on the container 2 is fastened by the spring arms 26 when placing the Ausbringröhrchens 8a be spread apart and the ribs 27 behind the attack surfaces of the applicator tube 8a grab.

The embodiments described above each show containers with two chambers 4a . 4b so these containers 1 are suitable for storing and simultaneously applying two components (two-component systems), for example base material and catalyst of a hardenable dental material. In principle, more than two chambers can be provided to discharge a larger number of different components. Further, the various arrangements of the chambers can be combined with each other and it can be selected different volume ratios of the individual chambers.

In the 18 to 23 Embodiments are shown in which the chambers 4a . 4b are arranged coaxially so that a chamber 4a the other chamber 4b encloses (tube in tube system). The transfer ram 15 is with one of the piston rod 14 widening central first operating section 16a and a surrounding, sleeve-like second operating portion 16b educated. The spring arms 26 are formed in this embodiment so that the Ausbringröhrchen 8a can be fastened by snapping.

Here is the Ausbringröhrchen 8a in the embodiment of the 18 to 20 relative to the fixed to the housing 2 fixed mixer helix 8b slidable to open or close the container. This is done via a on the Ausbringröhrchen 8a attached closure piston 11 as one in the closed position of the container in the discharge openings or the Ausbringstutzen 10 protruding sealing collar is formed. To open the container is the Ausbringröhrchen 8a together with the closing piston 11 advanced or pulled in the application direction, so that the Verschlusskol ben the discharge openings or the Ausbringstutzen 10 releases. The spring arms 26 indicate at their cover 3 facing away latching hook 27 on top of that the delivery tube 8a behind the mixer. Next is on the spring arms 26 each a locking projection 28a provided with two axially spaced locking recesses 28b on the delivery tube 8a can get in touch. The container is closed when the locking projections 28a in the front in Ausbringrichtung Rastausnehmungen 28b intervene ( 19 ), ie the Ausbringröhrchen 8a is in Direction of the lid 3 withdrawn, and the container is open when the latching projections 28a in the direction of application rear locking recesses 28b intervene ( 20 ), ie the Ausbringröhrchen 8a is advanced or withdrawn in the discharge direction.

In contrast, the Ausbringröhrchen 8a in the embodiment of the 21 to 23 through the locking hooks 27 the spring arms 26 firmly, ie immovable, fixed to the container. The closing or opening of the container takes place via closure piston 11 in the closed state of the container in the discharge openings 9a . 9b stuck ( 22 ). Due to the pressure of the components in the chambers, the shutter pistons can 11 into a space in the delivery tube 8a be advanced ( 23 ), so that the components on the closure piston 11 over into the delivery tube 8a can flow.

The details of the embodiments described above can be combined and / or replaced according to the requirements of the container. So can on each container a holding section 13 , a window 22 and / or a flange-like edge 25 be provided. Next, each container can be a pestle 24 to dispense the components or a suitable gun or the mixer and its attachment can be as in 18 be formed represented. In addition, the attachment of the Ausbringröhrchens 8a also on this provided spring arms 26 carried out on a corresponding structure on the housing 2 attack the container.
