Definitions
- the present invention relates to an arrangement for dispensing highly viscous liquids or liquids with a high solids content or with a content of larger solid segments according to the preamble of patent claim 1.
- An arrangement of the generic type is to be regarded as known with regard to normal liquids, in particular drinks, via the disclosure content of DE-OS 22 61 798.
- Container sizes between 5 and 20 kg are common for the commercial sector.
- Self-supporting containers are mainly used as packaging.
- these are usually canisters with screw caps;
- Flexible packaging, eg bags, is mainly intended only for containers without partial removal due to their insufficient seal strength.
- the object on which the present invention is based is to specify a dispensing arrangement of the generic type, the plastic container providing the material to be conveyed has optimal properties with regard to ecological and hygienic or microbiological conditions and requirements.
- the essence of the present invention is to form so-called flow channels on the plastic container, through which the container contents can be squeezed out well when the one container wall collapses.
- the effect can be further optimized in that the buckling half of the container consists of thin-walled material (cf. claim 2).
- the material to be dispensed is provided in a semi-flexible plastic container 1 known per se.
- This plastic container is filled to the brim and without air pockets.
- the combination of such a container with an integrated handle enables environmentally friendly transport to the consumer.
- a particularly favorable embodiment of this type of packaging is the subject of patent application P 39 04 080.
- the flexible container 1 filled with filling material is inserted into a pressure vessel 3 at the consumer.
- the plastic container 1 has a filling and removal nozzle 6, which is pressure-tightly connected to a delivery hose 7.
- the filling / removal nozzle 6 protrudes through the lid 2 locked with a bayonet lock on the pressure vessel 3 to the outside.
- a pressure medium preferably compressed air or water
- a pressure generator 4 and a pressure reducer 5 is introduced into the free space between the plastic container 1 and the pressure vessel 3 by means of a pressure generator 4 and a pressure reducer 5, and an overpressure P2 is thus built up to hold the flexible plastic container 1 collapses (see arrow a) and thereby presses the material to be conveyed into the conveying hose 7.
- the end of the conveyor hose 7 delivers the material to be conveyed directly or, if necessary, via a dispenser head.
- hose pinch valves 10, 11, 12, 13 are arranged in the exemplary embodiment shown, each of which is functionally coupled to a control valve 10 ', 11', 12 ', 13'.
- control valves are in turn coupled to the pressure generator 15 via a second pressure reducer 14; the pressure set via the second pressure reducer 14 and acting on the hose pinch valves 10 ... 13 has an overpressure P2 effective in the pressure vessel 3 compared to a higher pressure value P3.
- the control valves 10 '... 13' are activated in a specific and mutually coordinated sequence.
- the pinch valves 10 ... 13 squeeze the delivery hose 7 in a certain manner and press the conveyed material displaced into the delivery hose 7 by the collapse of the plastic container 1 in portions towards the end or exit of the delivery hose 7.
- the pinch valves 10 ... 13 allow volume-specific inclusion of a predetermined amount of material to be conveyed, which leads to exact dosing, regardless of the external conditions and hygienically or microbiologically clean.
- FIG. 4 shows - in two basic views - a plastic container 1 which is particularly suitable in connection with the concept described above.
- This plastic container 1 is generally produced in the drawing or blow molding process, two parallel-extruded film webs being formed in a two-part form.
- this conception has the particular advantages that the container half 1b, which is softer or more flexible due to the smaller thickness d2 or more flexible, and - as indicated by the arrow a - collapses evenly, so that ultimately the container contents are good , ie largely completely, can be squeezed out.
- the lower illustration of FIG. 4 in particular clearly shows how the more flexible container half 1b bends around the surrounding inverted seam 1a / b and nestles against the stiffer container half 1a from the inside.
- Fig. 2 shows a plastic container 1 in a perspective view.
- This can be one made of one and the same film material, but also one made of differently rigid film material according to FIG. 4.
- the special embodiment according to FIG. 2 is that the plastic container has so-called flow channels 65, which - relative to the outside of the container - are implemented as raised bulges. Good drainage is made possible in particular via these flow channels 65.
- FIG. 2 An almost completely empty plastic container 1 is shown here.
- the collapsed container wall presses against the wall with the filling / removal nozzle 6 and squeezes the remaining volume empty. This can escape in particular via the flow channels 65 to the filling / removal nozzle 6.
- the particularly good residual emptying is further supported by the fact that an annular channel 71 results on the circumferential weld seam 70 of the plastic container 1, which receives the residual content and ultimately expresses it. In order to prevent the collapsed wall from sticking to the connecting piece 6, this has notches 72, so that the residual emptying is also promoted in this way.
- the entire conveyor line can be cleaned by simply repositioning the connections of the delivery hoses 7, 7 'on the flexible plastic container 1 to a container filled with cleaning solution.
- the permeation of atmospheric oxygen must be kept low by a suitable choice of material and / or layer construction of the plastic container. This is particularly important for flexible plastic containers that are filled and emptied without air. With partial removal, the surface increases in relation to the filled volume, so that originally good permeation values can become very bad depending on the degree of filling. Under unfavorable operating conditions (long service life with low residual volume and very sensitive contents), this can ultimately lead to malfunctions.
- pressurized water is preferably used instead of compressed air for the pressurization of the transport container. Due to the complete containment of the transport container in the water, which under certain circumstances can even be tempered by recirculation, the dwell time is relatively long even in the opened state. Because for many foods there is an uninterrupted cold chain to the consumer should be guaranteed, overall less expensive container material can be selected.

Abstract
Description
Die vorliegende Erfindung bezieht sich auf eine Anordnung zum Dispensieren von hochviskosen Flüssigkeiten oder Flüssigkeiten mit hohem Feststoffanteil beziehungsweise mit einem Anteil an größeren Feststoffsegmenten nach dem Oberbegriff des Patentanspruchs 1.The present invention relates to an arrangement for dispensing highly viscous liquids or liquids with a high solids content or with a content of larger solid segments according to the preamble of
Eine Anordnung der gattungsgemäßen Art ist im Hinblick auf normale Flüssigkeiten, insbesondere Getränke, über den Offenbarungsgehalt der DE-OS 22 61 798 als bekannt zu betrachten.An arrangement of the generic type is to be regarded as known with regard to normal liquids, in particular drinks, via the disclosure content of DE-OS 22 61 798.
In der Lebensmitteltechnik werden häufig unterschiedliche Produkte aus visuellen, sensorischen und/oder auch Unverträglichkeitsgründen erst unmittelbar vor ihrer Verwendung zusammen dispensiert. Aus ähnlichen Gründen ist vielfach auch die Aufbewahrung der zu dispensierenden Produkte problematisch, und zwar insbesondere deshalb, weil infolge des Luftsauerstoffs häufig eine Eigenschaftsveränderung eintritt.In food technology, different products are often dispensed together for visual, sensory and / or intolerance reasons only immediately before they are used. For similar reasons, the storage of the products to be dispensed is often problematic, particularly because the properties of the air often change due to atmospheric oxygen.
Für den gewerblichen Bereich sind Gebindegrößen zwischen 5 und 20 kg üblich. Dabei werden als Verpackung überwiegend selbsttragende Behälter eingesetzt. Für niedrigund mittelviskose Produkte sind dies meist Kanister mit Schraubverschluß; für höherviskose Produkte und Produkte mit hohem Feststoffanteil bzw. mit größeren Segmenten sind dies üblicherweise Eimer mit Schnappdeckel. Flexible Verpackungen, z.B. Beutel, sind wegen ihrer ungenügenden Verschlußfestigkeit überwiegend nur für Gebinde ohne Teilentnahme vorgesehen.Container sizes between 5 and 20 kg are common for the commercial sector. Self-supporting containers are mainly used as packaging. For low and medium viscosity products, these are usually canisters with screw caps; For higher-viscosity products and products with a high solids content or with larger segments, these are usually buckets with a snap lid. Flexible packaging, eg bags, is mainly intended only for containers without partial removal due to their insufficient seal strength.
Im Zeitalter ökologischen Denkens werden häufig Mehrweggebinde gefordert. Dabei ist besonderes Augenmerk darauf zu richten, daß diese Verpackungen auch restlos entleert und umweltschonend entsorgt werden können. Bei Kanistern stellen, und zwar insbesondere bei mehrfacher Teilentnahme, die Restlosentleerbarkeit, sowie das Leervolumen ein besonderes Problem dar. Etwas besser eignen sich hier Eimer, die jedoch unter extremen Bedingungen schwierig zu verschließen sind. Flachfolienbeutel scheiden aus Gründen unzureichender Festigkeit und wegen Faltenbildung und/oder toter Ecken und dergleichen Unzulänglichkeiten für Anwendungen unter rauhen Betriebszuständen von vornherein aus. Lediglich die als Kompromiß zu diesen Verpackungsarten angebotenen flexiblen beziehungsweise halbflexiblen Beutelverpackungen werden den unterschiedlichen Forderungen im großen und ganzen gerecht.In the age of ecological thinking, reusable containers are often required. Particular attention should be paid to the fact that this packaging can also be completely emptied and disposed of in an environmentally friendly manner. In the case of canisters, particularly with multiple partial removal, the emptiness without residue and the empty volume represent a particular problem. Buckets are somewhat better here, but are difficult to close under extreme conditions. Flat film bags are ruled out from the outset for reasons of insufficient strength and because of wrinkling and / or dead corners and the like, inadequacies for applications under rough operating conditions. Only the flexible or semi-flexible pouch packaging offered as a compromise for these types of packaging largely meets the different requirements.
Die der vorliegenden Erfindung zugrunde liegende Aufgabe besteht darin, eine Ausbringanordnung der gattungsgemäßen Art anzugeben, deren das Fördergut bereitstellender Kunststoffbehälter im Hinblick auf ökologische und hygienische beziehungsweise mikrobiologische Bedingungen und Erfordernisse optimale Eigenschaften aufweist.The object on which the present invention is based is to specify a dispensing arrangement of the generic type, the plastic container providing the material to be conveyed has optimal properties with regard to ecological and hygienic or microbiological conditions and requirements.
Diese Aufgabe wird durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebene Lehre gelöst.This object is achieved by the teaching specified in the characterizing part of
Mit anderen-als im Patentanspruch 1 gebrauchten - Worten besteht der Kern der vorliegenden Erfindung darin, am Kunststoffbehälter sogenannte Fließkanäle anzuformen, über die beim Kollabieren der einen Behälterwandung der Behälterinhalt gut ausgequetscht werden kann. Die Wirkung kann noch dadurch optimiert werden, daß die einknickende Behälterhälfte aus dünnwandigerem Material besteht (vgl. Anspruch 2).In other words - than used in claim 1 - the essence of the present invention is to form so-called flow channels on the plastic container, through which the container contents can be squeezed out well when the one container wall collapses. The effect can be further optimized in that the buckling half of the container consists of thin-walled material (cf. claim 2).

Gemäß Fig. 1 ist das zu dispensierende Fördergut in einem an sich bekannten halbflexiblen Kunststoffbehälter 1 bereitgestellt. Dieser Kunststoffbehälter ist möglichst randvoll und ohne Lufteinschlüsse abgefüllt. Die Kombination eines derartigen Behälters mit einem integrierten Tragegriff ermöglicht ein umweltbewußtes Transportieren zum Verbraucher. Eine besonders günstige Ausführungsform dieser Verpackungsart ist Gegenstand der Patentanmeldung P 39 04 080. Beim Verbraucher wird - wie in Fig. 1 gezeigt - der mit Füllgut gefüllte flexible Behälter 1 in ein Druckgefäß 3 eingesetzt. Der Kunststoffbehälter 1 weist einen Füll- und Entnahmestutzen 6 auf, der druckdicht mit einem Förderschlauch 7 verbunden ist. Der Füll-/Entnahmestutzen 6 kragt durch den mit einem Bajonettverschluß am Druckgefäß 3 verriegelten Deckel 2 nach außen.1, the material to be dispensed is provided in a semi-flexible
In den Freiraum zwischen dem Kunststoffbehälter 1 und dem Druckgefäß 3 wird mittels eines Druckgenerators 4 und eines Druckminderers 5 ein Druckmedium, und zwar vorzugsweise Druckluft oder Wasser eingeleitet und so ein Überdruck P2 aufgebaut, der den flexiblen Kunststoffbehälter 1 kollabieren läßt (vgl. Pfeil a) und dabei das Fördergut in den Förderschlauch 7 preßt. Der Förderschlauch 7 gibt endseitig unmittelbar oder gegebenenfalls über einen Dispenserkopf das Fördergut ab.A pressure medium, preferably compressed air or water, is introduced into the free space between the
Längs der Förderstrecke, d.h. des Förderschlauchs 7 sind im dargestellten Ausführungsbeispiel vier Schlauch-Quetschventile 10, 11, 12,13 angeordnet, die je mit einem Ansteuerventil 10', 11', 12', 13' funktionell gekoppelt sind. Diese Ansteuerventile sind ihrerseits über einen zweiten Druckminderer 14 mit dem Druckgenerator 15 gekoppelt; der über den zweiten Druckminderer 14 eingestellte und die Schlauch-Quetschventile 10...13 beaufschlagende Druck hat einen dem im Druckgefäß 3 wirksamen überdruck P2 gegenüber höherern Druckwert P3. Die Ansteuerventile 10' ...13' werden in bestimmter und relativ zueinander aufeinander abgestimmter Folge aktiviert. Damit quetschen die Schlauch-Quetschventile 10...13 den Förderschlauch 7 in bestimmter Weise ab und drücken das über die Kollabierung des Kunststoffbehälters 1 in den Förderschlauch 7 verdrängte Fördergut portionsweise zum Ende beziehungsweise Ausgang des Förderschlauchs 7 hin. über die Schlauch-Quetschventile 10...13 ist so ein volumengenauer Einschluß einer vorgegebenen Menge an Fördergut möglich, was zu einer exakten Dosierung führt, und zwar unabhängig von den äußeren Bedingungen und hygienisch beziehungsweise mikrobiologisch rein.Along the conveyor line, i.e. of the delivery hose 7, four
Im Hinblick auf die Darstellung nach Fig. 1 soll noch darauf hingewiesen werden, daß der Förderschlauch 7 bei entlastetem Quetsch-Ventil aufgrund des im Druckgefäß 3 wirkenden überdrucks P2 gefüllt und durchmessermäßig rückgestellt wird, was damit auch zur Rückstellung des Quetschventils selbst führt.With regard to the representation according to FIG. 1, it should also be pointed out that the delivery hose 7 is filled and the diameter reset when the pinch valve is relieved due to the excess pressure P2 acting in the
Fig. 4 zeigt - und zwar in zwei Grundansichten - einen in Verbindung mit dem vorstehend beschriebenen Konzept besonders geeigneten Kunststoffbehälter 1. Dieser Kunststoffbehälter 1 wird im allgemeinen im Zieh- oder Blasformverfahren hergestellt, wobei zwei parallel extrudierte Folienbahnen in einer zweiteiligen Form ausgeformt werden. Gemäß dem in Fig. 4 dargestellten Beipiel werden nun Folienbahnen unterschiedlicher Dicke d1 beziehungsweise d2, d.h. Steifigkeit, verwandt und zwar derart, daß die mit dem Füll- /Entnahmestutzen 6 versehene Behälterhälfte 1a die relativ dickere (d1) und damit steifere ist.FIG. 4 shows - in two basic views - a
In Verbindung mit der erfindungsgemäßen Anordnung zum Pumpen und Dispensieren hat diese Konzeption die besonderen Vorteile, daß die aufgrund der geringeren Dicke d2 weichere, beziehungsweise flexiblere Behälterhälfte 1b relativ leicht und - wie durch den Pfeil a angedeutet - gleichmäßig kollabiert, so daß letztendlich der Behälterinhalt gut, d.h. weitgehend restlos, ausgequetscht werden kann. Die untere Darstellung von Fig. 4 läßt insbesondere klar erkennen, wie die flexiblere Behälterhälfte 1b um die sich bei der umgebenden Invertiernaht 1a/b umbiegt und sich von innen her an die steifere Behälterhälfte 1a anschmiegt.In connection with the arrangement for pumping and dispensing according to the invention, this conception has the particular advantages that the container half 1b, which is softer or more flexible due to the smaller thickness d2 or more flexible, and - as indicated by the arrow a - collapses evenly, so that ultimately the container contents are good , ie largely completely, can be squeezed out. The lower illustration of FIG. 4 in particular clearly shows how the more flexible container half 1b bends around the surrounding inverted
Fig. 2 zeigt einen Kunststoffbehälter 1 in perspektifischer Darstellung. Dabei kann es sich um einen solchen aus ein und demselben Folienmaterial, aber auch um einen solchen aus unterschiedlich steifem Folienmaterial entsprechend der Fig. 4 handeln. Die besondere Ausführungsform gemäß Fig. 2 besteht darin, daß der Kunststoffbehälter sogenannte Fließkanäle 65 aufweist, die - relativ zur Behälteraußenseite - als erhabene Ausbuchtungen realisiert sind. Über diese Fließkanäle 65 wird insbesondere eine gute Restentleerung ermöglicht.Fig. 2 shows a
Letzere soll in Form der Einzelheit aus Fig. 2 anhand von Fig. 3 näher erläutert werden. Hier ist ein fast vollständig entleerter Kunststoffbehälter 1 dargestellt. Die kollabierte Behälterwandung drückt gegen die Wandung mit dem Füll- /Entnahmestutzen 6 und quetschtdas Restvolumen leer. Dieses kann insbesondere über die Fließkanäle 65 zum Füll-/Entnahmestutzen 6 entweichen. Die besonders gute Restentleerung wird noch dadurch unterstützt, daß an der umlaufenden Schweißnaht 70 des Kunststoffbehälters 1 sich ein Ringkanal 71 ergibt, der den Restinhalt aufnimmt und letztlich ausdrückt. Um dabei zu verhindern, daß die kollabierte Wandung am Stutzen 6 festklebt, weist dieser Kerben 72 auf, so daß auch hierüber die Restentleerung begünstigt wird.The latter is to be explained in more detail in the form of the detail from FIG. 2 with reference to FIG. 3. An almost completely empty
Bezüglich der in der Zeichnung dargestellten Systeme soll noch folgendes angemerkt werden:With regard to the systems shown in the drawing, the following should also be noted:
Durch einfaches Umstecken der Anschlüsse der Förderschläuche 7,7' am flexiblen Kunststoffbehälter 1 auf einen mit Reinigungslösung gefüllten Behälter ist der gesamte Förderstrang zu reinigen.The entire conveyor line can be cleaned by simply repositioning the connections of the delivery hoses 7, 7 'on the flexible
Von besonderer Bedeutung sind in Verbindung mit dieser Erfindung folgende Zusammenhänge:
- Die besonders gute und restlose Ausbringung verschiedener hochviskoser und/oder Flüssigkeiten mit stückigen Komponenten durch Druckbeaufschlagung auf einen flexiblen Kunststoffbehälter in einem Druckbehälter;
- durch die Anordnung des erfindungsgemäß gestalteten flexiblen Kunststoffbehälters im Druckgefäß ist eine weitgehende Restmengenentleerung gewährleistet;
- durch stets gewechselten Kunststoffbehälter ergibt sich ein sehr günstiges mikrobiologisches Verhalten;
- erfolgt die Druckbeaufschlagung des mit Fördergut gefüllten Kunststoffbehälters durch Wasser, so ergibt sich eine Verringerung der spezifischen Oberfläche und damit eine Verlängerung der Haltbarkeit sauerstoffempfindlicher Produkte. (Dies gilt insbesondere bei Teilentnahme).
- The particularly good and complete application of various highly viscous and / or liquids with lumpy components by applying pressure to a flexible plastic container in a pressure container;
- The arrangement of the flexible plastic container designed according to the invention in the pressure vessel ensures that the remaining quantities are largely emptied;
- the constantly changed plastic container results in very favorable microbiological behavior;
- If the plastic container filled with the material to be conveyed is pressurized by water, the specific surface area is reduced and the durability of oxygen-sensitive products is extended. (This applies particularly to partial removal).
Für zahlreiche sauerstoffempfindliche Füllgüter muß durch eine geeignete Materialwahl und/oder Schichtenausführung des Kunststoffbehälters die Permeation von Luftsauerstoff gering gehalten werden. Eine besondere Bedeutung hat dies bei flexiblen Kunststoffbehältern, die ohne Luft abgefüllt und entleert werden. Bei Teilentnahme erhöht sich die Oberfläche im Verhältnis zum abgefüllten Volumen, so daß ursprünglich gute Permeationswerte je nach Füllgrad sehr schlecht werden können. Unter ungünstigen Betriebsbedingungen (lange Standzeit bei geringem Restvolumen und sehr empfindlichem Füllgut) kann dies letztlich zu Funktionsstörungen führen.For numerous oxygen-sensitive fillings, the permeation of atmospheric oxygen must be kept low by a suitable choice of material and / or layer construction of the plastic container. This is particularly important for flexible plastic containers that are filled and emptied without air. With partial removal, the surface increases in relation to the filled volume, so that originally good permeation values can become very bad depending on the degree of filling. Under unfavorable operating conditions (long service life with low residual volume and very sensitive contents), this can ultimately lead to malfunctions.
Diesem Verhalten ist durch andere Materialien nur bedingt zu begegnen. Aus diesem Grunde wird vorzugsweise für die Druckbeaufschlagung des Transportbehälters anstelle von Preßluft Druckwasser eingesetzt. Durch den völligen Einschluß des Transportbehälters im Wasser, welches unter Umständen sogar noch durch eine Umlaufkührung temperiert werden kann, ist somit die Verweilzeit auch im angebrochenen Zustand relativ hoch. Da für viele Nahrungsmittel eine ununterbrochene Kühlkette bis zum Verbraucher hin gewährleistet sein sollte, kann insgesamt eindeutig preiswerteres Behältermaterial gewählt werden.This behavior can only be countered to a limited extent with other materials. For this reason, pressurized water is preferably used instead of compressed air for the pressurization of the transport container. Due to the complete containment of the transport container in the water, which under certain circumstances can even be tempered by recirculation, the dwell time is relatively long even in the opened state. Because for many foods there is an uninterrupted cold chain to the consumer should be guaranteed, overall less expensive container material can be selected.
