Abstract

A device is described for dispensing flowable media, which device consists of a container with a tube of elastically deformable materials and a valve device in the tube part, the device having a stationary contact-pressure part and a pivotable lever possessing a contact-pressure surface. The pivotable lever serves to compress the tube section arranged between the contact-pressure part and the contact-pressure surface, opening the valve device and dispensing the medium contained in the tube, the tube being connected to a pivotable section of the lever.

Description

Die Erfindung betrifft eine Vorrichtung zur Abgabe fließfähiger Medien nach dem Oberbegriff des Patentanspruches 1.The invention relates to a device for dispensing flowable media according to the preamble of claim 1.

Herkömmliche Vorrichtungen der eingangs genannten Art werden insbesondere als Seifenspender verwendet und sind z.B. in der US-PS 4, 130, 224 beschrieben. Hierbei besitzt der Behälter einen flexiblen Schlauch, der mit dem Gehäuse der Vorrichtung fest verbunden ist und durch einen verschwenkbaren Hebel zusammengepreßt werden kann. Während der Benutzung dieser Vorrichtung ist jedoch nicht sichergestellt, daß der Benutzer das abgehende Medium auf die von ihm gewünschte Stelle seiner Hand verabreicht bekommt, zumal der Beginn der Abgabe des Mediums zum einen von der relativen Lage der Hand mit Bezug auf den Auslaß und zum anderen davon abhängig ist, in welcher Lage des Hebels das Ventil öffnet. Dies hat zur Folge, daß Benutzer mit langen Fingern und großen Handflächen das Medium regelmäßig auf die Finger verabreicht bekommen, während bei Personen mit kurzen Fingern nicht ausgeschlossen werden kann, daß das Medium den Bereich zwischen dem Handteller und dem Handgelenk beaufschlagt. Dies ist unerwünscht und kann sich vor allem dann als Nachteil erweisen, wenn der Benutzer langärmlige Wäschestücke trägt. Ferner sind in den EP 0 045 830 und 0 329 532 Seifenspender beschrieben, die mit vergleichbaren Nachteilen wie der eingangs genannte Seifenspender behaftet sind.Conventional devices of the type mentioned at the outset are used in particular as soap dispensers and are described, for example, in US Pat. No. 4, 130, 224. Here, the container has a flexible hose which is firmly connected to the housing of the device and can be pressed together by a pivotable lever. During the use of this device, however, it is not ensured that the user is given the outgoing medium to the desired location of his hand, especially since the start of the dispensing of the medium depends on the one hand on the relative position of the hand with respect to the outlet and on the other depends on the position of the lever in which the valve opens. As a result, users with long fingers and large palms are regularly given the medium on the fingers, while in the case of persons with short fingers it cannot be excluded that the medium will affect the area between the palm and the wrist. This is undesirable and can prove to be a disadvantage especially if the user wears long-sleeved items of laundry. Furthermore, EP 0 045 830 and 0 329 532 describe soap dispensers which have disadvantages comparable to those of the soap dispenser mentioned at the outset.

Der spender nach der EP 0 045 830 ist zusätzlich für körniges Material verwendbar. Schließlich ist in der dem Oberbegbriff des Anspruchcs 1 entsprechenden EP-A-110 686 ein Seifenspender offenbart, dessen Schlauch nicht nur im unteren Abgabebereich, sondern auch am anderen Ende eine Ventileinrichtung aufweist, um zu verhindern, daß die Seife bei Betätigen der Vorrichtung nur in einer bestimmten Richtung strömt. Dies ergibt sich u.a. aus der Tatsache, daß der Schlauch zum größten Teil gleichmäßig gequetscht wird und die Seife in beiden Richtungen des Schlauchs gleichmäßig verdrängt werden kann.The dispenser according to EP 0 045 830 can also be used for granular material. Finally, EP-A-110 686, which corresponds to the general concept of claim 1, discloses a soap dispenser whose hose has a valve device not only in the lower delivery area but also at the other end, in order to prevent the soap from only operating when the device is actuated flows in a certain direction. This results among other things. from the fact that the hose is squeezed evenly for the most part and the soap can be displaced evenly in both directions of the hose.

Ausgehend von dem obigen Stand der Technik liegt der Erfindung die Aufgabe zugrunde, die gattungsgemäße Vorrichtung ohne unangemessenen konstruktiven Aufwand so weiterzubilden, daß das Medium auf die gewünschte Stelle der Hand des Benutzers mit minimalen technischem Aufwand abgegeben werden kann.Based on the above prior art, the invention has for its object to further develop the generic device without undue design effort so that the medium can be delivered to the desired location of the hand of the user with minimal technical effort.

Die gestellte Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst.The object is achieved by the features of claim 1.

Man erkennt, daß die Erfindung jedenfalls dann verwirklicht ist, wenn der Auslaß mit Bezug auf die Hand des Benutzers eine feste Position aufweist, und zwar unabhängig davon, ob der Benutzer den Hebel festhält oder verschwenkt. Dadurch ist bei einer ordnungsgemäß eingestellten Vorrichtung sichergestellt, daß das Medium vorzugsweise auf den Handteller des Benutzers abgegeben wird.It can be seen that the invention is at least achieved when the outlet has a fixed position with respect to the hand of the user, regardless of whether the user holds the lever or pivots. This ensures with a properly adjusted device that the medium is preferably dispensed onto the user's palm.

Weitere zweckmäßige und vorteilhafte Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor.Further expedient and advantageous refinements of the invention emerge from the subclaims.

Eine zweckmäßige Maßnahme der Erfindung sieht vor, daß der Auslaß des Schlauches im unteren Bereich des Hebels angeordnet ist. Hierbei können diese Maßnahmen auch so getroffen sein, daß die der Andruckpartie zugekehrte Seite des Hebels eine mit ihm verbindbare Halteeinrichtung für den Auslaß aufweist. Im Rahmen dieses Erfindungsgedankens ist es besonders vorteilhaft, wenn der Hebel eine Stelleinrichtung mit einem Halteabschnitt umfaßt, dessen Lage in Längsrichtung des Hebels und auf diesem kontinuierlich einstellbar und hierbei feststellbar ist. Die Aufgabe der Halteeinrichtung ist, das Ende des Schlauches mit Bezug auf den Hebel so anzuordnen, daß es den Bewegungen des Hebels folgen kann.An expedient measure of the invention provides that the outlet of the hose is arranged in the lower region of the lever. These measures can also be taken in such a way that the side of the lever facing the pressure section has a holding device for the outlet which can be connected to it. In the context of this inventive concept, it is particularly advantageous if the lever comprises an actuating device with a holding section, the position of which can be continuously adjusted in the longitudinal direction of and on the lever and can thereby be ascertained. The task of the holding device is to arrange the end of the hose with respect to the lever so that it can follow the movements of the lever.

Ist die Vorrichtung insbesondere für Erwachsene vorgesehen, dann ist der veränderbare Abstand zwischen der Andruckpartie und dem Hebel größer zu wählen, während bei Vorrichtungen für Kinder, soll sie z.B. in Schulen und Kindergärten eingesetzt werden, der veränderbare Abstand kleiner gewählt wird.If the device is intended in particular for adults, then the variable distance between the pressure section and the lever should be chosen larger, while for devices for children, e.g. be used in schools and kindergartens, the variable distance is chosen smaller.

Eine weitere zweckmäßige Ausgestaltung sieht vor, daß die Halteeinrichtung eine den Auslaß festhaltenden Manschette aus elastischem Material besitzt, und daß die Lage der Stelleinrichtung in Längsrichtung des Hebels und auf diesem mittels einer Schraube veränderbar ist. Hierbei ist es besonders zweckmäßig, wenn die Ventileinrichtung von der Manschette gehalten ist. Der Behälter besteht regelmäßig aus einem aus Kunststoff bestehenden und verschweißten Beutel, in dem das Medium untergebracht ist. Der Beutel kann hierbei in dem Gehäuse der Vorrichtung untergebracht sein, wobei der Schlauch das untere Ende des Beutels definiert und mit dem Hebel fest verbunden ist.Another expedient embodiment provides that the holding device has a sleeve which holds the outlet and is made of elastic material, and that the position of the actuating device can be changed in the longitudinal direction of the lever and on this by means of a screw. It is particularly expedient here if the valve device is held by the sleeve. The container regularly consists of a plastic bag which is welded and in which the medium is housed. The bag can be accommodated in the housing of the device, the hose defining the lower end of the bag and being firmly connected to the lever.

Eine weitere zweckmäßige Ausgestaltung sieht vor, daß die Andruckfläche Teil eines am Hebel angelenkten Druckkörpers ist. Dieser Druckkörper kann am Hebel federnd gelagert sein. Ein Vorteil dieser Maßnahme besteht darin, daß auf den Schlauch nur ein bestimmter Druck ausgeübt werden kann, der jedoch kleiner ist als der maximale Federdruck des Druckkörpers. Werden nämlich Beutel aus einem dünnwandigen Kunststoff gewählt, dann könnte es unter Umständen zur Beschädigung des Schlauches kommen, wenn auf diesen Teil des Beutels ein unangemessen hoher Druck augeübt wird. Eine weitere zweckmäßige Ausgestaltung sieht vor, daß die Andruckpartie Teil eines Plattenkörpers ist, dessen relative Lage mit Bezug auf den Hebel veränderbar ist. Dadurch kann die Andruckpartie als Mittel zur Bestimmung der Abgabemenge des Mediums vorgesehen sein.Another useful embodiment provides that the pressure surface is part of a pressure body articulated on the lever. This pressure body can be resiliently mounted on the lever. An advantage of this measure is that only a certain pressure can be exerted on the hose, which, however, is less than the maximum spring pressure of the pressure body. If bags made of thin-walled plastic are chosen, the hose could be damaged if an inappropriately high pressure is exerted on this part of the bag. Another useful embodiment provides that the pressure section is part of a plate body, the relative position of which can be changed with respect to the lever. As a result, the pressure section can be provided as a means for determining the amount of medium to be dispensed.

Für das Nachfüllen der Vorrichtung mit Medium ist es besonders zweckmäßig, wenn der Schlauch und der Behälter einstückig und aus demselben Werkstoff ausgebildet sind. Dies hat den Vorteil, daß der entleerte Beutel ausgehängt und durch einen neuen ersetzt werden kann. Im Rahmen dieses Erfindungsgedankens ist es besonders zweckmäßig, wenn das obere Ende des Schlauches von einem Träger der Vorrichtung gehalten ist.For refilling the device with medium, it is particularly expedient if the hose and the container are made in one piece and are made of the same material. This has the advantage that the emptied bag can be unhooked and replaced with a new one. In the context of this inventive concept, it is particularly expedient if the upper end of the hose is held by a carrier of the device.

In den Fig. 1 bis 7 ist eine Vorrichtung zur Abgabe fließfähiger Medien, z.B. Seife, Putzmittel oder dgl., die in einem Behälter 10 mit einem eine Ventileinrichtung 12 aufweisenden Schlauch 14 aus elastisch verformbaren Werkstoff angeordnet sind, dargestellt. Die Vorrichtung besteht aus einem Grundkörper 8 und einem Gehäuse 40, das mittels nicht näher dargestellter Halteeinrichtungen mit dem Grundkörper 8 lösbar verbindbar ist. Der Grundkörper 8 ist mit einer Wand 46 fest verbindbar und besitzt im oberen Bereich einen Träger 42 mit Haken 44. Die Haken 44 tragen den als Beutel ausgebildeten Behälter 10, in dem das Medium 22 untergebracht ist. Das Medium 22 kann flüssig, pastös oder auch körnig sein. Das untere Ende des Behälters 10 läuft in den Schlauch 14 aus, der im Übergangsbereich einen Ring 6 trägt, der sich auf einer Stütze 32 des Grundkörpers 8 abstützt. Die Stütze 32 besitzt eine Sicherung 30, durch die sichergestellt werden soll, daß der Schlauch 14 sich von der Stütze 32 nicht von selbst löst. An diese Stütze 32 ist auch der Hebel 20 angelenkt, der eine Andruckfläche 18 in Form einer angelenkten Platte trägt. Der Gelenkpunkt 26 der Andruckfläche 18 ist im mittleren Bereich des Hebels angeordnet, während das andere Ende des Körpers eine Druckfeder 24 aufweist, durch die die auf den Schlauch 14 wirkende Kraft teilweise reguliert werden kann. Die Andruckpartie 16 ist ebenfalls von einer Platte gebildet, die mit dem Grundkörper 8 gelenkig oder fest verbindbar ist, deren Neigungswinkel jedoch mittels einer Schraube 23 einstellbar ist. Von dem Neigungswinkel α der Andruckpartie 16 hängt es ab, welche Menge des im Schlauch 14 befindlichen Mediums ausgepreßt wird. Der Neigungswinkel α ist durch die Geraden 13 und 15 definiert, die sich oberhalb des Hebels 20 schneiden. Er kann von 0° bis 45° eingestellt werden, und zwar stufenlos. Größere Winkel können ebenfalls eingestellt werden, sie sind jedoch von geringerer Bedeutung. Im Bereich des Betätigungsabschnittes 2 des Hebels 20 ist eine Halteeinrichtung 36 vorgesehen, welche die Ventileinrichtung 12 festhält. Auf der Bodenseite der Halteeinrichtung 36 befindet sich der Auslaß 48 des Schlauches 14.1 to 7 show a device for dispensing flowable media, for example soap, cleaning agent or the like, which are arranged in a container 10 with a valve 14 having a hose 14 made of elastically deformable material. The device consists of a base body 8 and a housing 40 which can be detachably connected to the base body 8 by means of holding devices (not shown). The base body 8 can be firmly connected to a wall 46 and has a support 42 with hooks 44 in the upper region. The hooks 44 carry the container 10, which is designed as a bag and in which the medium 22 is accommodated. The medium 22 can be liquid, pasty or also granular. The lower end of the container 10 runs out into the hose 14, which carries a ring 6 in the transition region, which is supported on a support 32 of the base body 8. The support 32 has a fuse 30 to ensure that the hose 14 does not come loose from the support 32 by itself. The lever 20 is also articulated to this support 32 and carries a pressure surface 18 in the form of an articulated plate. The hinge point 26 of the pressure surface 18 is arranged in the central region of the lever, while the other end of the body has a compression spring 24, by means of which the force acting on the hose 14 can be partially regulated. The pressure section 16 is also formed by a plate which can be connected to the base body 8 in an articulated or fixed manner, but whose angle of inclination can be adjusted by means of a screw 23. It depends on the angle of inclination α of the pressure section 16 how much of the medium in the hose 14 is squeezed out. The angle of inclination α is defined by the straight lines 13 and 15 which intersect above the lever 20. It can be set from 0 ° to 45 °, infinitely. Larger angles can also be set, but they are of less importance. In the area of the actuating section 2 of the lever 20, a holding device 36 is provided which holds the valve device 12 in place. The outlet 48 of the hose 14 is located on the bottom side of the holding device 36.

Die Fig. 1 und 2 Lassen ferner erkennen, daß der Grundkörper 8 Ausnehmungen 39 für den Grundkörper 8 hintergreifenden Haken 43 sowie Ausnehmungen 37 für Positionierkörper 41 aufweist. Die vertikalen Längsseiten des Grundkörpers 8 weisen im oberen und im unteren Bereich Einschnitte 33 und 35 auf, die mit Vorsprüngen des Gehäuses 40 Lösbar verbindbar sind. Der Betätigungsabschnitt 2 besitzt eine rechteckförmige Ausnehmung 27, in die ein Vorsprung 25 der Halteeinrichtung 36 einsteckbar ist. Der Behälter 10 besitzt in seinem oberen, vom Schlauch 14 abgekehrten Bereich eine Verstärkungspartie 9, die sicherstellt, daß der Behälter nicht durchhängt, wenn er z.B. halbvoll ist.1 and 2 also show that the base body 8 has recesses 39 for the base body 8 engaging hook 43 and recesses 37 for the positioning body 41. The vertical long sides of the base body 8 have incisions 33 and 35 in the upper and in the lower area, which can be detachably connected to projections of the housing 40. The actuating section 2 has a rectangular recess 27 into which a projection 25 of the holding device 36 can be inserted. The container 10 has in its upper area facing away from the hose 14 a reinforcement section 9 which ensures that the container does not sag when e.g. is half full.

Der in den Fig. 3 und 4 dargestellten Vorrichtung ist zu entnehmen, daß der Grundkörper 8 zwei Haken 44 aufweist, in die der Behälter 10, der zwei kreisrunde Augen 50 aufweist, einhängbar ist. Im unteren Bereich des Behälters 10 sind ebenfalls zwei Augen 52 vorgesehen, in die zwei Dorne 54 einsteckbar sind. Der Behälter 10 ist daher endseitig fixiert, so daß die Bewegung des Hebels 20 keine Auswirkungen auf seine Lage innerhalb des Gehäuses haben. Der Hebel 20 ist in Form eines Bügels mit zwei Schenkeln 56 und 58 ausgebildet, die in ihrem unteren Bereich den Betätigungsabschnitt 2 aufweisen. Die Schenkel 56 und 58 sind um die Achse 60 verschwenkbar und können die in den Fig. 5 bis 7 dargestellte Positionen einnehmen. In ihrem oberen Drittel sind die Schenkel 56 und 58 gekröpft, um die Schwenkachse 60 möglichst im Bereich der Längsmittelachse 62 des Schlauches anbringen zu können. In dieser Position des Hebels 20 ist erfahrungsgemäß seine beste Wirkung erzielbar. Von einzelnen Teilen der Vorrichtung, z.B. der Druckfeder 24, abgesehen, kann die Vorrichtung aus Kunststoff bestehen, wobei die Teile durch Spritzgießverfahren herstellbar sind. Durch Aushängen des Gehäuses 40 wird eine Arbeitslage erreicht, wie sie in den Fig. 3 und 4 dargestellt ist. Hier kann nun der entleerte Behälter 10 ausgehängt und durch einen neuen ersetzt werden. Die Fig. 5, 6 und 7 zeigen, daß beim Betätigen des Hebels 20 in Richtung des Pfeiles 1 der minimale Abstand d zwischen der Andruckpartie 16 und der Andruckfläche 18 verringert wird, bis eine Position erreicht ist, bei der das im Schlauch befindliche Medium nicht mehr nach oben strömen kann. Ab diesem Zeitpunkt wird bei weiterem Betätigen des Hebels 20 auf das im Schlauchabschnitt befindliche Medium Druck ausgeübt, was dazu führt, daß das Ventil öffnet und das im Schlauch befindliche Medium nach außen gelangen kann. Die Öffnung 48 ist in diesem Ausführungsbeispiel Teil der Ventileinrichtung 12, die vorzugsweise als ein Überdruckventil ausgebildet ist. Welches Ventil für welches Medium angewandt wird, kann experimentell festgestellt und danach eingesetzt werden. Bei flüssigen oder pastösen Medien kann, wie bereits erwähnt, zweckmäßigerweise ein Überdruckventil verwendet werden, während bei körnigem Material ein Schlitzmembranventil vorteilhaft genutzt werden kann. Nach Erreichen der Anschlagstelle (Fig. 7) wird der Hebel 20 freigemacht, wobei er die in Fig. 5 dargestellte Ausgangsposition einnimmt. Daraufhin strömt in den Schlauch 14 das im Behälter 10 befindliche Medium, wodurch er aufgefüllt wird und die in Fig. 5 dargestellte Form einnimmt. Ein erneutes Betätigen der Vorrichtung ist somit möglich.The device shown in FIGS. 3 and 4 shows that the base body 8 has two hooks 44, into which the container 10, which has two circular eyes 50, can be hung. In the lower area of the container 10, two eyes 52 are also provided, into which two mandrels 54 can be inserted. The container 10 is therefore fixed at the end, so that the movement of the lever 20 has no effect on its position within the housing. The lever 20 is designed in the form of a bracket with two legs 56 and 58, which have the actuating section 2 in their lower region. The legs 56 and 58 can be pivoted about the axis 60 and can assume the positions shown in FIGS. 5 to 7. The legs 56 and 58 are cranked in their upper third in order to be able to attach the pivot axis 60 as far as possible in the region of the longitudinal central axis 62 of the hose. Experience has shown that the best effect can be achieved in this position of the lever 20. Apart from individual parts of the device, for example the compression spring 24, the device can be made of plastic, the parts being able to be produced by injection molding. By unhooking the housing 40, a working position is achieved, as shown in FIGS. 3 and 4. Here the emptied container 10 can now be unhooked and replaced by a new one. 5, 6 and 7 show that when the lever 20 is actuated in the direction of arrow 1, the minimum distance d between the pressure section 16 and the pressure surface 18 is reduced until a position is reached in which the medium in the hose is not can flow more upwards. From this point in time, upon further actuation of the lever 20, pressure is exerted on the medium in the hose section, which leads to the valve opening and the medium in the hose being able to escape to the outside. In this exemplary embodiment, opening 48 is part of valve device 12, which is preferably designed as a pressure relief valve. Which valve is used for which medium can be determined experimentally and then used will. As already mentioned, a pressure relief valve can expediently be used in the case of liquid or pasty media, while a slit diaphragm valve can advantageously be used in the case of granular material. After reaching the stop point (Fig. 7), the lever 20 is released, taking the starting position shown in Fig. 5. The medium in the container 10 then flows into the hose 14, as a result of which it is filled up and assumes the shape shown in FIG. 5. It is therefore possible to operate the device again.

Die Fig. 8 und 9 zeigen, daß der Hebel 20 eine Stelleinrichtung 3 trägt, die in Richtung des Doppelpfeiles 21 vertikal verstellbar ist. Im Hebel 20 ist ein etwa mittiger und vertikal sich erstreckender Schlitz 17 ausgebildet, der vom Niet 19 mit Kopf durchquert ist. Der Niet verbindet die Stelleinrichtung 3 mit dem Hebel 20. Die Stelleinrichtung ist im Querschnitt etwa U-förmig, und ihre Schenkel 45 und 47 besitzen mehrere Stufen 5 und 7, durch die der Abstand der Andruckpartie 16 von der Andruckfläche 18 bestimmbar ist. Soll aus dem Schlauch 14 wenig Medium gepreßt werden, dann stützt sich die Andruckpartie 16 an der untersten Stufe 5 ab, während sie sich im anderen Falle an der oberen Stufe 7 abstützt. Die Stelleinrichtung ist leicht zugänglich und betätigbar, und zwar ohne daß die Vorrichtung zerlegt werden müßte.8 and 9 show that the lever 20 carries an adjusting device 3 which is vertically adjustable in the direction of the double arrow 21. An approximately central and vertically extending slot 17 is formed in the lever 20 and is crossed by the head 19 with the rivet 19. The rivet connects the actuating device 3 to the lever 20. The actuating device is approximately U-shaped in cross-section, and its legs 45 and 47 have a plurality of steps 5 and 7, by means of which the distance of the pressure section 16 from the pressure surface 18 can be determined. If little medium is to be pressed out of the hose 14, the pressure section 16 is supported on the lowest step 5, while in the other case it is supported on the upper step 7. The actuating device is easily accessible and can be actuated without the device having to be disassembled.

Die durch die Erfindung erzielten Vorteile bestehen insbesondere darin, daß der Benutzer mit dem Medium nur dann in Berührung kommt, wenn er den Hebel 20 betätigt. Beim Auswechseln des Behälters 10 wird auch der Schlauch 14, der beim Betätigen des Hebels 20 mechanisch beansprucht wird, ausgewechselt. Eine Abnutzung und Funktionsuntüchtigkeit des Hebels kommt hier kaum in Betracht, da er eine deutlich höhere Festigkeit und Härte als der Schlauch aufweist. Der Schlauch wird zwar mechanisch beansprucht, seine Beschädigung kommt nicht in Betracht, da er nach einer beschränkten Anzahl von Entnahmen des Mediums ausgewechselt wird.The advantages achieved by the invention are in particular that the user only comes into contact with the medium when he actuates the lever 20. When the container 10 is replaced, the hose 14, which is mechanically stressed when the lever 20 is actuated, is also replaced. Wear and inoperability of the lever can hardly be considered here, as it is clearly higher strength and hardness than the hose. Although the hose is mechanically stressed, its damage is out of the question since it is replaced after a limited number of times the medium has been removed.
