- the object of the invention is to develop a generic discharge to the effect that in a particularly simple manner handling with targeted mixing of the media is possible.
- the object of the invention is also to provide a production technology favorable discharge device available, with an automatic change of the mixing ratio of the two media can be realized.
- the conveying device for conveying medium with the features of the marked part of claim 1 is formed.
- a manual actuation of the actuating handle by a user has two conveying operations result.
- part of the medium from the first medium reservoir is discharged through the discharge opening into an environment in the manner known per se.
- the second medium is transferred from the second medium storage in the first medium storage in response to the actuation of the actuating handle.
- the two conveying processes can take place simultaneously or one after the other.
- the discharge device can be designed such that the delivery of the second medium into the first medium reservoir of the delivery of the medium from the first medium reservoir to the discharge opening is connected downstream.
- a pressure-dependent opening valve is provided between the medium reservoirs. This valve interrupts the connection between the first and the second medium reservoir, provided that the pressure in the first medium reservoir is not smaller by a valve-specific differential pressure than the pressure in the second medium reservoir is.
- a valve is in particular a valve with a pressure-elastically deflectable valve body in question.
- the discharge device is designed and filled accordingly, that the entire second medium is transferred in the course of a single operation of the actuating handle in the first medium storage.
- a design is considered to be particularly advantageous in which, in response to actuation of the actuating handle, only a portion of the medium from the second medium reservoir is conveyed into the first medium reservoir while a portion of the second medium remains in the second medium reservoir.
- Such a design in which the medium from the second medium storage is transferred stepwise with each renewed actuation of the actuating handle in the first medium storage, offers the advantage that the mixing ratio of the medium in the first medium storage changes gradually.
- the volume of the second medium reservoir is dimensioned such that when initially completely filled second medium reservoir in response to at least five, preferably at least ten actuations of the actuating handle each carried a promotion of a portion of the second medium in the first medium storage.
- a discharge device it is not intended that a mixing of the media from the first and the second Media storage takes place by destruction or otherwise removal of an intermediate wall.
- a likewise provided with the actuating handle second conveyor may be provided, which is coupled to the first and the second medium storage that it promotes the second medium from the second medium storage in the first medium storage in the course of actuation of the actuating handle and preferably at the same time.
- first medium reservoir is connected to an environment with the intermediary of the second medium reservoir, wherein preferably a connecting channel is provided between the first and the second medium reservoir at the lower end of the second medium reservoir.
- the negative pressure which is generated in a preferably dimensionally stable and volume-constant first medium storage by a discharge process, leads to a pressure equalization with the outer environment of the discharge.
- this pressure equalization initially does not take place or at least not exclusively with air entering the first medium reservoir from the environment, but with the second medium from the second medium reservoir.
- the negative pressure generated by a discharge operation is thus used to effect a pressure equalization through the second medium reservoir after each discharge operation or upon reaching a sufficiently large negative pressure in the first medium reservoir.
- the second medium reservoir is not permanently connected to the environment for the purpose of sucking in air from the environment.
- the conveyor is designed such that it allows limited in terms of time and / or quantity of air in the course of a conveying operation. This prevents that at a liquid level in the second medium reservoir above the liquid level of the first liquid reservoir, the medium flows unintentionally into the first medium reservoir. This is prevented by a negative pressure in the second medium storage or the phased air access to the second medium storage.
- the pressure-dependent opening valve is designed such that the second medium only in a negative pressure of at least 100 mbar, preferably at least 200mbar, more preferably at least 400mbar, in the first medium storage relative to the second medium storage in the first medium storage can penetrate.
- a particularly advantageous embodiment of a discharge device provides that the first medium storage bottle-like is formed and has a connection opening, on which a discharge head is mounted, which in turn comprises the conveyor.
- the second medium reservoir is suspended by the connection opening in the first medium reservoir and rests on an edge of the connection opening of the first medium reservoir.
- the first medium reservoir can be filled with the first medium through the connection opening in order subsequently to suspend the already filled or still unfilled second medium reservoir into the first medium reservoir. If the second medium storage is still unfilled during hanging, it can subsequently also be filled through the connection opening. Therefore, a filling plant can be used, in which the first and the second medium are introduced successively by directly juxtaposed filling nozzles in the discharge. Furthermore, regardless of the total size of the first medium reservoir, the same type of second medium reservoir can always be used given an identical size of the connection opening.
- a riser pipe protruding into the first medium reservoir is provided, the second medium reservoir being delimited at least in sections by an outer side of a section of this riser.
- the riser fulfills a dual function in such a design. First, it serves as a supply line from the first medium storage to the conveyor. On the other hand, it limits the second medium storage.
- the second medium reservoir can be limited by further walls, which are either designed as separate components or are formed integrally with the riser.
- the second medium reservoir surrounds the inner wall forming portion of the riser ring and is bounded on the outside by a cylindrical and substantially coaxial with this section of the riser outer wall.
- the outer wall may preferably be formed integrally with the portion of the riser forming the inner wall.
- one part of the riser pipe is formed integrally with the remaining walls of the second medium reservoir. while a subsequent part of the riser, which adjoins the first part at the lower end, is formed as a separate component, which is attached to the first part of the riser depending on the type of the first medium reservoir used.
- the dispensing device contains a first medium in the first medium store and a second medium in the second medium store, wherein these are cosmetic or pharmaceutical media.
- the media in the first and in the second medium storage differ from each other, so that it can be achieved that initially the pure or almost pure first medium is discharged and then a mixture of media is discharged with leaps or gradually increasing proportion of the second medium.
- the two media form a two-component self-tanner, wherein preferably only the second medium contains the sugar required for tanning, in particular dihydroxyacetone or erythrulose.
- the first medium in this case is a moisturizer which is able to moisturize the skin of the user, so that the effect of said sugar is improved and, in particular, homogenized.
- FIGS. 1a to 1h show a dispensing device according to the invention in various stages of use.
- the discharge device 10 has an approximately bottle-like container 20, at the upper end of a bottle neck 22 is provided with a connection opening 24.
- a cap 26 is placed, which is screwed in a manner not shown on the bottle neck 22 of the container 20 or otherwise secured thereto.
- a pump module 40 is clamped in a conventional manner.
- This pump module 40 shown cut in half has two mutually stationary housing sections 41, 42 and in the housing 41, 42 against the force of a return spring 43 movable piston unit 44.
- the piston unit 44 itself consists of an upwardly projecting out of the pump unit 40 outlet 45 with pump outlet 51 and further piston components 46, 47.
- an inlet port 48 with pump inlet channel 52 is provided through which a fluid connection to a volume-variable pumping chamber 50 of the pumping unit 40 exists through the interposition of an inlet valve 49.
- a spray head 60 is placed, on the upper side of an actuating surface 62 is provided and includes an outlet opening 64 connected to the Pumpauslasskanal 51.
- the piston unit 44 of the pump module 40 can be displaced within the housing 41, 42, thus triggering a pumping operation.
- the operation of the pump module 40 does not differ from the operation of known comparable pump modules.
- When already filled with medium dosing 50 leads a displacement of the piston unit 44 down to a relative displacement of the piston members 46, 47 against each other, whereby a flow path between the metering chamber 50 and the outlet channel 51 is opened.
- a continuation of the movement of the piston unit 44 downwards then leads subsequently to a discharge of the medium from the metering chamber 50 through the outlet channel 51 and the outlet opening 64 of the spray head 60 through to the outside.
- the peculiarity of the dispensing device shown lies in the design and the coupling of the media storage.
- two media storage 70, 80 are arranged.
- an insert 30 is suspended in the container 20, which has at its upper end a collar 32 which rests on the bottleneck 22 with the interposition of a lower sealing ring 28a.
- the substantially rotationally symmetrical insert 30 has two concentric cylindrical walls 34, 36, wherein the outer wall 34 is connected at its lower end by means of a conical portion 34 a with the inner wall 36.
- the suitability for suspending this insert 30 results from the outer diameter of the outer wall 34, which is smaller than the inner diameter of the connection opening 24, and from the outer diameter of the collar 32, which does not fit through the connection opening 24.
- the inner wall 34 of the insert 30 simultaneously forms the upper part of a riser 53, through which the pump module 40 is supplied with medium.
- the container 20 and the insert 30 delimit the two mentioned media reservoirs 70, 80.
- the first medium reservoir 70 is on the outside bounded by the outer wall of the container 20 and on the inside by the outer wall 34 of the insert 30. This first medium reservoir is connected to the pump module 40 via said riser 53.
- the second medium reservoir 80 is bounded on the outside by the outer wall 34 of the insert 30 and on the inside by the inner wall of the insert 30 forming the riser 53.
- the media storage 70, 80 are connected to each other via a connecting channel 76, which in the state of FIG. 1a is closed by a pressure-responsive opening valve 78.
- the first medium 12 is in the initial state of FIG. 1a stored within the first medium storage 70. It is symbolized by small white circles.
- the second medium 14 is in the initial state of FIG. 1 a stored exclusively within the second medium storage 80. It is symbolized by small black circles.
- the piston unit 44 returns to the in Figure 1c manner shown together with the spray head 60 under the action of the return spring 43 in its initial position, shown in FIG Figure 1d , back.
- the inlet valve 49 opens, so that first medium 12 is again drawn in along the arrow 90 into the pumping chamber 50 through the inlet channel 52 and the riser 53. This results in a lowering of the liquid level of the first medium 12 in the first medium reservoir 20, which is indicated by the dashed line 12 'in the Figure 1c and 1d is clarified.
- the reduction of the amount of the first medium in the first medium reservoir 70 causes a negative pressure in the first medium reservoir 70, which can not be compensated initially, since the only access to the first medium reservoir 20 through the second medium reservoir 80 and the connecting channel 76 is given by the vacuum generated in the first medium reservoir 70 is not sufficient to open the valve 78 between the medium reservoirs 70, 80.
- the amount of the first medium 12 in the first medium reservoir is further reduced, so that the negative pressure in the first medium reservoir continues to increase due to lack of pressure equalization.

Description
Die Erfindung betrifft eine Austragvorrichtung für flüssige oder pastöse Medien nach dem Oberbegriff von Anspruch 1.The invention relates to a discharge device for liquid or pasty media according to the preamble of claim 1.
Gattungsgemäße Austragvorrichtungen sind aus dem Stand der Technik bekannt. Die Gestaltung von Austragvorrichtungen mit zwei Mediumspeichern, die mit unterschiedlichen Medien befüllt oder befüllbar sind, erlaubt es, diese Medien erst unmittelbar vor einem Austragvorgang zu durchmengen. Dies gestattet es beispielsweise, dass Mischungsverhältnis zwischen dem ersten und dem zweiten Medium fallweise anzupassen.Generic discharge devices are known from the prior art. The design of discharge devices with two medium reservoirs, which are filled or filled with different media, allows these media to be passed through just before a discharge process. This makes it possible, for example, to adjust the mixing ratio between the first and the second medium on a case-by-case basis.
Aus dem pharmazeutischen Bereich sind Austragvorrichtungen bekannt, bei denen zwei Medien, insbesondere eine Trägerflüssigkeit und ein pulverförmiges Medium, unmittelbar vor einem Austragvorgang durchmischt werden, indem zunächst das Medium aus einem der Mediumspeicher in den anderen gefördert wird, so dass es zu einer Durchmengung kommt. Nachfolgend wird dann das hierdurch erzeugte Mischmedium durch die Austragöffnung hindurch ausgetragen.From the pharmaceutical field discharge devices are known in which two media, in particular a carrier liquid and a powdery medium, are mixed immediately before a discharge process by first the medium from one of the media storage is promoted in the other, so that it comes to a Durchmengung. Subsequently, the mixed medium thus produced is then discharged through the discharge opening.
Aus dem pharmazeutischen Bereich sind Austragvorrichtungen bekannt, bei denen aus zwei Mediumspeichern mittels einer gemeinsamen Betätigungshandhabe jeweils Medium gefördert wird, wobei sich die geförderten Medien nachfolgend in einer Mischkammer durchmengen und dann gemeinsam ausgetragen werden.From the pharmaceutical field discharge devices are known in which medium is conveyed from each medium by means of a common actuating handle, wherein the conveyed media subsequently pass through in a mixing chamber and then discharged together.
Aus der
Aufgabe der Erfindung ist es, eine gattungsgemäße Austragvorrichtung dahingehend weiterzubilden, dass in einer besonders einfachen Art und Weise eine Handhabung mit gezielter Durchmischung der Medien möglich wird. Aufgabe der Erfindung ist es weiterhin, eine herstellungstechnisch günstige Austragvorrichtung zur Verfügung zu stellen, mit der eine automatische Veränderung des Mischungsverhältnisses der beiden Medien realisiert werden kann.The object of the invention is to develop a generic discharge to the effect that in a particularly simple manner handling with targeted mixing of the media is possible. The object of the invention is also to provide a production technology favorable discharge device available, with an automatic change of the mixing ratio of the two media can be realized.
Erfindungsgemäß ist hierfür vorgesehen, dass die Fördereinrichtung zur Förderung von Medium mit den Merkmalen des kennzeichneten Teils des Anspruchs 1 ausgebildet ist.According to the invention, it is provided for this purpose that the conveying device for conveying medium with the features of the marked part of claim 1 is formed.
Bei einer erfindungsgemäßen Austragvorrichtung ist vorgesehen, dass eine manuelle Betätigung der Betätigungshandhabe durch einen Benutzer zwei Fördervorgänge zur Folge hat. Zum einen wird in der an sich üblichen Weise ein Teil des Mediums aus dem ersten Mediumspeicher durch die Austragöffnung hindurch an eine Umgebung abgegeben. Darüber hinaus wird jedoch in Reaktion auf die Betätigung der Betätigungshandhabe auch das zweite Medium aus dem zweiten Mediumspeicher in den ersten Mediumspeicher überführt. Die beiden Fördervorgänge können gleichzeitig erfolgen oder aber nacheinander. Insbesondere kann die Austragvorrichtung derart ausgebildet sein, dass das die Förderung des zweiten Mediums in den ersten Mediumspeicher der Förderung des Mediums aus dem ersten Mediumspeicher zur Austragöffnung nachgeschaltet ist. Durch eine Betätigung der Betätigungshandhabe kommt es im ersten Mediumspeicher zu einer Durchmischung des ersten Mediums und des aus dem zweiten Mediumspeicher stammenden zweiten Mediums.In a discharge device according to the invention it is provided that a manual actuation of the actuating handle by a user has two conveying operations result. On the one hand, part of the medium from the first medium reservoir is discharged through the discharge opening into an environment in the manner known per se. In addition, however, the second medium is transferred from the second medium storage in the first medium storage in response to the actuation of the actuating handle. The two conveying processes can take place simultaneously or one after the other. In particular, the discharge device can be designed such that the delivery of the second medium into the first medium reservoir of the delivery of the medium from the first medium reservoir to the discharge opening is connected downstream. By actuating the actuating handle, the first medium and the second medium originating from the second medium reservoir are mixed in the first medium reservoir.
Für den Benutzer ist es nicht erforderlich, eine gesonderte von der Betätigungshandhabung abweichende Vorbereitungshandlung vorzunehmen, um die Durchmischung zu erzielen. Stattdessen wird die dem Benutzer ohnehin bekannte Art und Weise der Betätigung einer Austragvorrichtung sowohl für den Austrag selbst als auch für die Durchmischung der Medien im ersten Mediumspeicher genutzt.It is not necessary for the user to make a separate preparatory action other than the actuation handling in order to achieve thorough mixing. Instead, the user already known manner of actuation of a discharge is used both for the discharge itself and for the mixing of the media in the first medium storage.
Um besonders zuverlässig eine ungewollte Vermengung der Medien im ersten und im zweiten Mediumspeicher zu verhindern, ist erfindungsgemäß vorgesehen, dass zwischen den Mediumspeichern ein druckabhängig öffnendes Ventil vorgesehen ist. Dieses Ventil unterbricht die Verbindung zwischen dem ersten und dem zweiten Mediumspeicher, sofern der Druck im ersten Mediumspeicher nicht um einen ventilspezifischen Differenzdruck kleiner als der Druck im zweiten Mediumspeicher ist. Als Ventil kommt insbesondere ein Ventil mit einem unter Druckeinwirkung elastisch auslenkbaren Ventilkörper in Frage.In order to prevent unwanted mixing of the media in the first and in the second medium storage particularly reliable, it is provided according to the invention that a pressure-dependent opening valve is provided between the medium reservoirs. This valve interrupts the connection between the first and the second medium reservoir, provided that the pressure in the first medium reservoir is not smaller by a valve-specific differential pressure than the pressure in the second medium reservoir is. As a valve is in particular a valve with a pressure-elastically deflectable valve body in question.
Bei einer besonders einfachen Gestaltung ist die Austragvorrichtung dafür ausgebildet und entsprechend befüllt, dass das gesamte zweite Medium im Zuge einer einzigen Betätigung der Betätigungshandhabe in den ersten Mediumspeicher überführt wird.In a particularly simple design, the discharge device is designed and filled accordingly, that the entire second medium is transferred in the course of a single operation of the actuating handle in the first medium storage.
Als besonders vorteilhaft wird jedoch eine Gestaltung angesehen, bei der in Reaktion auf eine Betätigung der Betätigungshandhabe nur ein Teil des Mediums aus dem zweiten Mediumspeicher in den ersten Mediumspeicher gefördert wird, während ein Teil des zweiten Mediums im zweiten Mediumspeicher verbleibt. Eine solche Gestaltung, bei der das Medium aus dem zweiten Mediumspeicher schrittweise mit jeder erneuten Betätigung der Betätigungshandhabe in den ersten Mediumspeicher überführt wird, bietet den Vorteil, dass das Mischungsverhältnis des Mediums im ersten Mediumspeicher sich schrittweise ändert. So kann bei einer ersten Betätigung der Betätigungshandhabe ein Austrag von reinem ersten Medium erfolgen, während bei späteren Betätigungen der Betätigungshandhabe der Anteil des zweiten Mediums am ausgetragenen Medium ansteigt, bis die Gesamtheit des zweiten Mediums in den ersten Mediumspeicher überführt wurde, so dass ab diesem Zeitpunkt ein gleichbleibendes Mischungsverhältnis bei dem ausgetragenen Medium vorliegt. Vorzugsweise ist das Volumen des zweiten Mediumspeichers derart bemessen, dass bei anfangs vollständig gefülltem zweitem Mediumspeicher in Reaktion auf mindestens fünf, vorzugsweise mindestens zehn Betätigungen der Betätigungshandhabe jeweils eine Förderung eines Teils des zweiten Mediums in den ersten Mediumspeicher erfolgt.However, a design is considered to be particularly advantageous in which, in response to actuation of the actuating handle, only a portion of the medium from the second medium reservoir is conveyed into the first medium reservoir while a portion of the second medium remains in the second medium reservoir. Such a design, in which the medium from the second medium storage is transferred stepwise with each renewed actuation of the actuating handle in the first medium storage, offers the advantage that the mixing ratio of the medium in the first medium storage changes gradually. Thus, during a first actuation of the actuation handle, a discharge of pure first medium takes place, while with subsequent actuations of the actuation handle, the proportion of the second medium on the discharged medium increases until the entirety of the second medium has been transferred into the first medium reservoir, so that from this point in time a constant mixing ratio is present in the discharged medium. Preferably, the volume of the second medium reservoir is dimensioned such that when initially completely filled second medium reservoir in response to at least five, preferably at least ten actuations of the actuating handle each carried a promotion of a portion of the second medium in the first medium storage.
Bei einer erfindungsgemäßen Austragvorrichtung ist es nicht vorgesehen, dass eine Vermengung der Medien aus dem ersten und dem zweiten Mediumspeicher durch eine Zerstörung oder anderweitige Entfernung einer Zwischenwandung erfolgt. Stattdessen kann beispielsweise eine ebenfalls mit der Betätigungshandhabe vorgesehene zweite Fördereinrichtung vorgesehen sein, die derart an den ersten und den zweiten Mediumspeicher gekoppelt ist, dass sie im Zuge einer Betätigung der Betätigungshandhabe und vorzugsweise zeitgleich das zweite Medium aus dem zweiten Mediumspeicher in den ersten Mediumspeicher fördert.In a discharge device according to the invention, it is not intended that a mixing of the media from the first and the second Media storage takes place by destruction or otherwise removal of an intermediate wall. Instead, for example, a likewise provided with the actuating handle second conveyor may be provided, which is coupled to the first and the second medium storage that it promotes the second medium from the second medium storage in the first medium storage in the course of actuation of the actuating handle and preferably at the same time.
Als besonders vorteilhaft wird es angesehen, wenn der erste Mediumspeicher mit einer Umgebung unter Zwischenschaltung des zweiten Mediumspeichers verbunden ist, wobei vorzugsweise ein Verbindungskanal zwischen dem ersten und dem zweiten Mediumspeicher am unteren Ende des zweiten Mediumspeichers vorgesehen ist.It is considered to be particularly advantageous if the first medium reservoir is connected to an environment with the intermediary of the second medium reservoir, wherein preferably a connecting channel is provided between the first and the second medium reservoir at the lower end of the second medium reservoir.
Bei einer solchen Gestaltung führt der Unterdruck, der im vorzugsweise formstabilen und volumenkonstanten ersten Mediumspeicher durch einen Austragvorgang erzeugt wird, zu einem Druckausgleich mit der äußeren Umgebung der Austragvorrichtung. Da jedoch der zweite Mediumspeicher zwischengeschaltet ist, erfolgt dieser Druckausgleich zunächst nicht oder zumindest nicht ausschließlich mit in den ersten Mediumspeicher eindringender Luft aus der Umgebung, sondern mit dem zweiten Medium aus dem zweiten Mediumspeicher. Bei einer solchen Gestaltung wird demnach der durch einen Austragvorgang erzeugte Unterdruck genutzt, um nach jedem Austragvorgang oder bei Erreichen eines ausreichend großen Unterdrucks im ersten Mediumspeicher durch den zweiten Mediumspeicher hindurch einen Druckausgleich zu bewirken. Durch eine Anordnung des Verbindungskanals am unteren Ende des zweiten Mediumspeichers ist dabei gewährleistet, dass es zu einem Eindringen von Luft in den ersten Mediumspeicher erst dann kommt, wenn der zweite Mediumspeicher vollständig oder annähernd vollständig entleert wurde. Die Angabe des unteren Endes bezieht sich dabei auf die bestimmungsgemäße Ausrichtung der Austragvorrichtung während des Austragvorgangs.In such a design, the negative pressure, which is generated in a preferably dimensionally stable and volume-constant first medium storage by a discharge process, leads to a pressure equalization with the outer environment of the discharge. However, since the second medium reservoir is interposed, this pressure equalization initially does not take place or at least not exclusively with air entering the first medium reservoir from the environment, but with the second medium from the second medium reservoir. In such a design, the negative pressure generated by a discharge operation is thus used to effect a pressure equalization through the second medium reservoir after each discharge operation or upon reaching a sufficiently large negative pressure in the first medium reservoir. By arranging the connection channel at the lower end of the second medium reservoir, it is ensured that air only enters the first medium reservoir when the second medium reservoir has been completely or almost completely emptied. The indication of the lower end refers to the intended orientation of the discharge during the discharge.
Vorzugsweise ist auch der zweite Mediumspeicher nicht dauerhaft mit der Umgebung zum Zwecke des Einsaugens von Luft aus der Umfebung verbunden. Stattdessen ist vorzugsweise die Fördereinrichtung derart ausgebildet, dass sie lediglich im Zuge eines Fördervorgangs zeitlich und/oder mengenmäßig begrenzt das Eindringen von Luft gestattet. Hierdurch wird verhindert, dass bei einem Flüssigkeitsspiegel im zweiten Mediumspeicher über dem Flüssigkeitsspiegel des ersten Flüssigkeitsspeichers das Medium unbeabsichtigt in den ersten Mediumspeicher strömt. Die wird durch einen Unterdruck im zweiten Mediumspeicher bzw. den phasenweise verschlossenen Luftzugang zum zweiten Mediumspeicher verhindert.Preferably, the second medium reservoir is not permanently connected to the environment for the purpose of sucking in air from the environment. Instead, preferably, the conveyor is designed such that it allows limited in terms of time and / or quantity of air in the course of a conveying operation. This prevents that at a liquid level in the second medium reservoir above the liquid level of the first liquid reservoir, the medium flows unintentionally into the first medium reservoir. This is prevented by a negative pressure in the second medium storage or the phased air access to the second medium storage.
Besonders von Vorteil ist es, wenn das druckabhängig öffnende Ventil derart ausgebildet ist, dass das zweite Medium erst bei einem Unterdruck von mindestens 100 mbar, vorzugsweise von mindestens 200mbar, insbesondere vorzugsweise von mindestens 400mbar, im ersten Mediumspeicher gegenüber dem zweiten Mediumspeicher in den ersten Mediumspeicher eindringen kann.It is particularly advantageous if the pressure-dependent opening valve is designed such that the second medium only in a negative pressure of at least 100 mbar, preferably at least 200mbar, more preferably at least 400mbar, in the first medium storage relative to the second medium storage in the first medium storage can penetrate.
Hierdurch wird erreicht, dass nach Inbetriebnahme der Austragvorrichtung eine gewisse Zahl von Austragvorgängen durchgeführt werden muss, bevor erstmalig die Verbindung zwischen den Mediumspeichern geöffnet wird und dadurch das zweite Medium in den ersten Mediumspeicher eindringt. Daraus resultiert, dass bei den ersten Austragvorgängen lediglich das erste Medium ausgetragen wird und es erst später zu einer Durchmengung des ersten und des zweiten Mediums im ersten Mediumspeicher kommt. Dies kann beispielsweise bei kosmetischen Anwendungen von Vorteil sein, bei denen bestimmungsgemäß vorgesehen ist, dass zunächst für einige Tage eine erste Lotion in reiner Form auf der Haut aufgetragen wird und erst nach dem Einwirken dieser ersten Lotion in Reinform bei nachfolgenden späteren Anwendungen eine vorzugsweise schrittweise Ergänzung mit einer zweiten Lotion oder einem gesonderten weiteren Wirkstoff erfolgt.This ensures that after commissioning of the discharge a certain number of Austragvorgängen must be performed before the connection between the medium reservoirs is opened for the first time and thus the second medium penetrates into the first medium reservoir. As a result, only the first medium is discharged during the first discharge processes and only later does the first medium reservoir become mixed up in the first medium reservoir. This may be advantageous, for example, in cosmetic applications in which it is intended that initially for a few days a first lotion in pure form is applied to the skin and only after the action of this first lotion in pure form in subsequent subsequent applications, preferably a stepwise supplementation with a second lotion or a separate further active ingredient.
Eine besonders vorteilhafte Ausgestaltung einer erfindungsgemäßen Austragvorrichtung sieht vor, dass der erste Mediumspeicher flaschenar-tig ausgebildet ist und eine Verbindungsöffnung aufweist, an der ein Austragkopf angebracht ist, der seinerseits die Fördereinrichtung umfasst. Dabei ist der zweite Mediumspeicher durch die Verbindungsöffnung in den ersten Mediumspeicher eingehängt und liegt auf einem Rand der Verbindungsöffnung des ersten Mediumspeichers auf.A particularly advantageous embodiment of a discharge device according to the invention provides that the first medium storage bottle-like is formed and has a connection opening, on which a discharge head is mounted, which in turn comprises the conveyor. In this case, the second medium reservoir is suspended by the connection opening in the first medium reservoir and rests on an edge of the connection opening of the first medium reservoir.
Eine solche Gestaltung erlaubt eine sehr vorteilhaft einfache Befüllung des Mediumspeichers sowie eine einfache Montage der Austragvorrichtung. So kann zunächst der erste Mediumspeicher mit dem ersten Medium durch die Verbindungsöffnung hindurch befüllt werden, um nachfolgend den bereits befüllten oder noch unbefüllten zweiten Mediumspeicher in den ersten Mediumspeicher hineinzuhängen. Sofern der zweite Mediumspeicher beim Einhängen noch unbefüllt ist, kann er nachfolgend ebenfalls durch die Verbindungsöffnung hindurch befüllt werden. Daher kann eine Befüllungsanlage Anwendung finden, bei der das erste und das zweite Medium durch unmittelbar nebeneinander angeordnete Befüllungsdüsen nacheinander in die Austragvorrichtung eingebracht werden. Weiterhin kann bei identischer Größe der Verbindungsöffnung unabhängig von der Gesamtgröße des ersten Mediumspeichers stets der gleiche Typ des zweiten Mediumspeichers Verwendung finden.Such a design allows a very advantageous simple filling of the medium storage and a simple assembly of the discharge. Thus, first of all, the first medium reservoir can be filled with the first medium through the connection opening in order subsequently to suspend the already filled or still unfilled second medium reservoir into the first medium reservoir. If the second medium storage is still unfilled during hanging, it can subsequently also be filled through the connection opening. Therefore, a filling plant can be used, in which the first and the second medium are introduced successively by directly juxtaposed filling nozzles in the discharge. Furthermore, regardless of the total size of the first medium reservoir, the same type of second medium reservoir can always be used given an identical size of the connection opening.
Vorzugsweise ist vorgesehen, dass zur Förderung des Mediums aus dem ersten Mediumspeicher zur Austragöffnung ein in den ersten Mediumspeicher hineinragendes Steigrohr vorgesehen ist, wobei der zweite Mediumspeicher zumindest abschnittsweise durch eine Außenseite eines Abschnitts dieses Steigrohrs begrenzt wird. Das Steigrohr erfüllt bei einer solchen Gestaltung eine Doppelfunktion. Zum einen dient es als Zuleitung vom ersten Mediumspeicher zur Fördereinrichtung. Zum anderen begrenzt es den zweiten Mediumspeicher. Der zweite Mediumspeicher kann dabei durch weitere Wandungen begrenzt werden, die entweder als separate Bauteile ausgebildet sind oder aber einstückig mit dem Steigrohr ausgebildet sind.It is preferably provided that for conveying the medium from the first medium reservoir to the discharge opening, a riser pipe protruding into the first medium reservoir is provided, the second medium reservoir being delimited at least in sections by an outer side of a section of this riser. The riser fulfills a dual function in such a design. First, it serves as a supply line from the first medium storage to the conveyor. On the other hand, it limits the second medium storage. The second medium reservoir can be limited by further walls, which are either designed as separate components or are formed integrally with the riser.
Besonders bevorzugt ist hierbei eine Gestaltung, bei der der zweite Mediumspeicher ringförmig den eine Innenwandung bildenden Abschnitt des Steigrohrs umgibt und außenseitig durch eine zylindrische und im Wesentlichen koaxial zu diesem Abschnitt des Steigrohrs ausgerichtete Außenwandung begrenzt wird. Dabei kann die Außenwandung vorzugsweise einstückig mit dem die Innenwandung bildenden Abschnitt des Steigrohrs ausgebildet sein.Particularly preferred in this case is a design in which the second medium reservoir surrounds the inner wall forming portion of the riser ring and is bounded on the outside by a cylindrical and substantially coaxial with this section of the riser outer wall. In this case, the outer wall may preferably be formed integrally with the portion of the riser forming the inner wall.
Da es als vorteilhaft angesehen wird, wenn für verschiedene Typen von ersten Mediumspeichern stets der gleiche Typ des zweiten Mediumspeichers Verwendung findet, kann bei einer besonderen Ausgestaltung der Austragvorrichtung vorgesehen sein, dass ein Teil des Steigrohrs mit den übrigen Wandungen des zweiten Mediumspeichers einstückig ausgebildet ist, während ein sich daran anschließender Teil des Steigrohrs, der sich am unteren Ende an den ersten Teil anschließt, als separates Bauteil ausgebildet ist, welches in Abhängigkeit des verwendeten Typs des ersten Mediumspeichers an dem ersten Teil des Steigrohrs befestigt wird.Since it is considered advantageous if the same type of second medium reservoir is always used for different types of first medium reservoirs, it can be provided in a particular embodiment of the discharge device that one part of the riser pipe is formed integrally with the remaining walls of the second medium reservoir. while a subsequent part of the riser, which adjoins the first part at the lower end, is formed as a separate component, which is attached to the first part of the riser depending on the type of the first medium reservoir used.
Besonders von Vorteil ist es, wenn die erfindungsgemäße Austragvorrichtung im ersten Mediumspeicher ein erstes Medium und im zweiten Mediumspeicher ein zweites Medium enthält, wobei es sich um kosmetische oder pharmazeutische Medien handelt. Dabei unterscheiden sich die Medien im ersten und im zweiten Mediumspeicher voneinander, so dass erreicht werden kann, dass zunächst das reine oder fast reine erste Medium ausgetragen wird und anschließend ein Mediengemisch mit sprunghaft oder schrittweise ansteigendem Anteil des zweiten Mediums ausgetragen wird. Dies stellt insbesondere bei Hauptpflegeprodukten einen Vorteil dar, bei denen die Wirksamkeit des zweiten Mediums von einer Vorbehandlung mit dem ersten Medium abhängt.It is particularly advantageous if the dispensing device according to the invention contains a first medium in the first medium store and a second medium in the second medium store, wherein these are cosmetic or pharmaceutical media. In this case, the media in the first and in the second medium storage differ from each other, so that it can be achieved that initially the pure or almost pure first medium is discharged and then a mixture of media is discharged with leaps or gradually increasing proportion of the second medium. This is an advantage, in particular in the case of main care products, in which the effectiveness of the second medium depends on a pretreatment with the first medium.
Von besonderem Vorteil ist es insbesondere, wenn die beiden Medien einen Zweikomponenten-Selbstbräuner bilden, wobei vorzugsweise nur das zweite Medium den für die Bräunung erforderlichen Zucker, insbesondere Dihydroxyaceton oder Erythrulose enthält. Besonders von Vorteil ist es, wenn das erste Medium in diesem Fall eine Feuchtigkeitscreme ist, die in der Lage ist, die Haut des Benutzers mit Feuchtigkeit zu versehen, so dass die Wirkung des genannten Zuckers verbessert und insbesondere homogenisiert wird.It is particularly advantageous in particular if the two media form a two-component self-tanner, wherein preferably only the second medium contains the sugar required for tanning, in particular dihydroxyacetone or erythrulose. It is particularly advantageous if the first medium in this case is a moisturizer which is able to moisturize the skin of the user, so that the effect of said sugar is improved and, in particular, homogenized.

Zwischen dem Flaschenhals 22 und dem Aufsatz 26 ist in an sich bekannter Art und Weise ein Pumpenmodul 40 eingespannt. Dieses halbseitig geschnitten dargestellte Pumpenmodul 40 weist zwei zueinander ortsfeste Gehäuseabschnitte 41, 42 sowie eine im Gehäuse 41, 42 gegen die Kraft einer Rückstellfeder 43 bewegliche Kolbeneinheit 44 auf. Die Kolbeneinheit 44 selbst besteht aus einem nach oben aus der Pumpeneinheit 40 hinausragenden Auslassstutzen 45 mit Pumpenauslasskanal 51 sowie weiteren Kolbenbauteilen 46, 47. Am unteren Ende des Pumpenmoduls 40 ist ein Einlassstutzen 48 mit Pumpeneinlasskanal 52 vorgesehen, durch den hindurch unter Zwischenschaltung eines Einlassventils 49 eine Fluidverbindung zu einer volumenveränderlichen Pumpkammer 50 der Pumpeinheit 40 besteht.Between the
Auf den Auslassstutzen 45 der Pumpeinheit 44 ist ein Sprühkopf 60 aufgesetzt, an dessen Oberseite eine Betätigungsfläche 62 vorgesehen ist und der eine mit dem Pumpauslasskanal 51 verbundene Auslassöffnung 64 umfasst. Durch manuelles Niederdrücken des Sprühkopfes 60 kann die Kolbeneinheit 44 des Pumpenmoduls 40 innerhalb des Gehäuses 41, 42 verlagert werden und somit ein Pumpvorgang ausgelöst werden.On the
Die Funktionsweise des Pumpenmoduls 40 unterscheidet sich nicht von der Funktionsweise bekannter vergleichbarer Pumpenmodule. Bei bereits mit Medium befüllter Dosierkammer 50 führt eine Verlagerung der Kolbeneinheit 44 nach unten zu einer Relativverlagerung der Kolbenbauteile 46, 47 gegeneinander, wodurch ein Strömungspfad zwischen der Dosierkammer 50 und dem Auslasskanal 51 geöffnet wird. Eine Weiterführung der Bewegung der Kolbeneinheit 44 nach unten führt sodann nachfolgend zu einem Austrag des Mediums aus der Dosierkammer 50 durch den Auslasskanal 51 und die Austrittsöffnung 64 des Sprühkopfes 60 hindurch nach außen. Wenn anschließend unter der Wirkung der Rückstellfeder 43 die Kolbeneinheit 44 wieder nach oben verlagert wird, kommen die Kolbenbauteile 46, 47 wieder in unmittelbarem Kontakt aneinander, so dass im Zuge der fortgeführten Rückstellbewegung der Kolbeneinheit 44 nach oben ein Unterdruck in der sich vergrößernden Pumpkammer 50 entsteht, durch welchen das Einlassventil 49 geöffnet wird. Anschließend wird durch den Einlasskanal 52 hindurch Medium von unten angesogen, bis der Ausgangszustand der Pumpeneinheit 40 mit befüllter Pumpkammer 50 wieder hergestellt ist.The operation of the
Die Besonderheit bei der dargestellten Austragvorrichtung liegt in der Gestaltung und der Kopplung der Mediumspeicher. Innerhalb des flaschenartigen Behälters 20 sind zwei Mediumspeicher 70, 80 angeordnet. Zu diesem Zweck ist ein Einsatz 30 in den Behälter 20 eingehängt, der an seinem oberen Ende einen Kragen 32 aufweist, der unter Zwischenschaltung eines unteren Dichtrings 28a auf dem Flaschenhals 22 aufliegt. Der im Wesentlichen rotationssymmetrische Einsatz 30 weist zwei konzentrische zylindrische Wandungen 34, 36 auf, wobei die äußere Wandung 34 an ihrem unteren Ende mittels eines konischen Abschnitts 34a mit der inneren Wandung 36 verbunden ist. Die Eignung zum Einhängen dieses Einsatzes 30 ergibt sich aus dem Außendurchmesser der äußeren Wandung 34, der kleiner als der Innendurchmesser der Verbindungsöffnung 24 ist, sowie aus dem Außendurchmesser des Kragens 32, der durch die Verbindungsöffnung 24 nicht hindurchpasst.The peculiarity of the dispensing device shown lies in the design and the coupling of the media storage. Within the bottle-

Der Behälter 20 sowie der Einsatz 30 begrenzen die beiden genannten Mediumspeicher 70, 80. Der erste Mediumspeicher 70 wird außenseitig durch die Außenwandung des Behälters 20 und innenseitig durch die Außenwandung 34 des Einsatzes 30 begrenzt. Dieser erste Mediumspeicher ist mit dem Pumpenmodul 40 über das genannte Steigrohr 53 verbunden.The
Der zweite Mediumspeicher 80 wird außenseitig durch die Außenwandung 34 des Einsatzes 30 und innenseitig durch die das Steigrohr 53 bildende Innenwandung des Einsatzes 30 begrenzt. Die Mediumspeicher 70, 80 sind über einen Verbindungskanal 76 miteinander verbunden, der im Zustand der

Ein solcher Austragvorgang des Gemisches 13 ist in
Mit weiteren Austragvorgängen kommt es schrittweise zu weiterem Eindringen des zweiten Mediums 14 aus dem zweiten Mediumspeicher 80 in den ersten Mediumspeicher 70, so dass sich die Konzentration des zweiten Mediums 14 innerhalb des Mediengemisches 13 im ersten Mediumspeicher 70 schrittweise erhöht, bis der Flüssigkeitsspiegel des zweiten Mediums 14 im zweiten Mediumspeicher 80 in der
