Die Erfindung betrifft einen Einwegbehälter für einen fließfähigen Baustoff, insbesondere für ein flüssiges oder pastöses Medium zur bautechnischen Verarbeitung insbesondere auf einer Baustelle. Der fließfähige Baustoff kann beispielsweise ein bereits für den Einsatz fertiger, angerührter Beton oder Putz oder eine Farbe oder ein anderes fließfähiges Medium sein, unter welches auch ein Granulat fallen könnte, welches insbesondere auf einer Baustelle Einsatz finden müsste. Deren Einwegbehälter soll die Fähigkeit haben, den fließfähigen Baustoff fluiddicht zu halten, so dass der Baustoff bis zu seinem Einsatz ausreichend lang gelagert werden kann. Der Einwegbehälter muss ausreichend stabil und fest realisierbar sein, um eine platzsparende Lagerung, insbesondere eine Stapelung im unbefüllten Zustand, möglich zu machen. Ferner soll er nach dem bestimmungsgemäßen Einsatz des Baustoffes einfach und umweltschonend zu entsorgen sein.

Der Auslassstutzen ist mit der Innenauskleidung verschweißt, um einen baustoffdichten Transport von dem Baustoffaufnahmeraum über den Auslassstutzen nach außen zu gewährleisten. Bei dem bekannten Einwegcontainer zeigte sich als Nachteil, dass die Innenauskleidung insbesondere im Bereich des Schweißanschlusses an den Auslassstutzen beim Anschließen einer üblicherweise zum Abziehen des Baustoffes behilflichen Fördereinrichtung, wie einen Airless-Förderer, beschädigt werden kann. Insbesondere unerfahrenes Bedienpersonal erkennt die empfindliche Struktur der Innenauskleidung insbesondere an der Verbindungsschweißnaht nicht von außerhalb des Einwegcontainers. Ein Reißen oder anderweitiges Beschädigen der Innenauskleidung kann dazu führen, dass kein ausreichender Sog zum Abziehen des Baustoffes aus dem Baufstoffaufnahmeraum hervorgerufen werden kann.

Diese Aufgabe wird durch die Merkmale von Anspruch 1 gelöst.This object is solved by the features of claim 1.

Demnach ist ein Einwegbehälter für einen fließfähigen Baustoff, wie oben angegeben ist, vorgesehen, der eine Behälterstruktur aufweist, die einen Baustoffaufnahmeraum begrenzt. Die Behälterstruktur stellt den formstabilen Behälterkörper dar, der bei einer bevorzugten Ausführung der Erfindung ausschließlich aus Kartonage besteht. Auf den erfindungsgemäßen Aufbau der Behälterstruktur und dessen Bestandteile wird später eingegangen. Der Baustoffaufnahmeraum wird durch Innenflächen der Wandung und des Bodens der Behälterstruktur begrenzt und ist von einer formkomplementären Innenauskleidung bedeckt. Die Innenauskleidung, die auch als Einlage bezeichnet werden kann, ist vorzugsweise in Form eines geschlossenen Sackes oder Beutels realisiert, der fluiddicht, insbesondere gasdicht, realisier ist und vor dem fluiddichten Verschließen mit dem Baustoff befüllbar ist. Bei und nach der Befüllung schmiegt der von dem Baustoff auf die Innenauskleidung wirkende Fülldruck die formkomplementäre Innenauskleidung an die Innenfläche des Baustoffaufnahmeraums derart an, dass die Innenauskleidung formschlüssig, insbesondere faltenfrei, flächig daran anliegt. Die flexible Innenauskleidung ist vorzugsweise aus einer Folie insbesondere aus Kunststoff realisiert, die eine obere große, insbesondere verschließbare Öffnung zum Befüllen und einen unteren kleinen Auslass bildet, der insbesondere kreisringförmig gestaltet ist und benachbart einem Durchgang in der starren Behälterstruktur zugeordnet ist, über den der Baustoff von dem Einwegbehälter abgegeben werden soll. Der Durchgang ist vorzugsweise in dem Boden der Behälterstruktur angebracht. Er kann allerdings auch in einem Wandabschnitt der Behälterstruktur ausgebildet sein. Vorzugsweise ist der Durchgang an einer (in Bezug auf die Gravitationsrichtung) tiefsten Stelle des Baustoffaufnahmeraums, so dass unter dem Einfluss der Schwerkraft der fließfähige Baustoff selbständig hin zum Durchgang gelangt. Des Weiteren ist ein Auslassstutzen baustoffdicht, insbesondere fluiddicht, vorzugsweise gasdicht, am Auslass der Innenauskleidung an einen Auslassstutzen gekoppelt, wobei der Auslassstutzen insbesondere durch ein starreres Material als die Innenauskleidung realisiert ist. Erfindungsgemäß ist der Auslassstutzen an der formstabilen Behälterstruktur benachbart dem Durchgang befestigt. Erfindungsgemäß kann hierzu eine Befestigungseinrichtung im Bereich des Durchgangs vorgesehen sein, die entweder durch die Behälterstruktur selbst, wie eine entsprechende Formdimensionierung des Durchgangs in der Behälterstruktur im Verhältnis zu dem Auslassstutzen, oder durch eine separate Einrichtung beispielsweise mittels hinzugefügter Befestigungskomponenten realisiert ist. Es zeigte sich, dass der an der formstabilen Behälterstruktur fixierte Auslassstutzen einen Schutz vor sensiblen Verbindungsstellen, wie Schweißstellen, förderaufwärts des Auslassstutzens an der Innenauskleidung bietet. Bei einem unvorsichtigen Betätigen der Abfördereinrichtung insbesondere beim An- oder Abschließen einer Abfördereinrichtung an dem Auslassstutzen werden die Betätigungskräfte über den Auslassstutzen an die Behälterstruktur abgeleitet und eine Verletzung der sensiblen Innenauskleidung ist verhindert.Accordingly, a disposable container for a flowable building material, as stated above, is provided, which has a container structure that limits a building material receiving space. The container structure represents the dimensionally stable container body, which in a preferred embodiment of the invention consists exclusively of cardboard. On the construction of the container structure and its components according to the invention will be discussed later. The building material receiving space is limited by inner surfaces of the wall and the bottom of the container structure and is covered by a shape-complementary inner lining. The inner lining, which may also be referred to as an insert, is preferably realized in the form of a closed bag or bag, which is fluid-tight, in particular gas-tight, realisier and can be filled with the building material before the fluid-tight closure. During and after filling, the filling pressure acting on the inner lining of the building material conforms to the shape-complementary inner lining to the inner surface of the building material receiving space in such a way that the inner lining rests on it in a form-fitting manner, in particular wrinkle-free. The flexible inner lining is preferably made of a film, in particular made of plastic, which forms an upper large, in particular closable opening for filling and a lower small outlet, which is designed in particular annular and adjacent to a passage in the rigid container structure is assigned, over which the building material to be dispensed from the disposable container. The passage is preferably mounted in the bottom of the container structure. However, he can also in a wall portion of the container structure be educated. Preferably, the passage is at one (in relation to the gravitational direction) lowest point of the building material receiving space, so that under the influence of gravity, the flowable building material passes independently to the passage. Furthermore, an outlet nozzle is construction-material-tight, in particular fluid-tight, preferably gas-tight, at the outlet the inner lining is coupled to an outlet nozzle, wherein the outlet nozzle is realized in particular by a more rigid material than the inner lining. According to the invention, the outlet nozzle is attached to the dimensionally stable container structure adjacent to the passage. According to the invention, for this purpose, a fastening device can be provided in the region of the passage, which is realized either by the container structure itself, such as a corresponding shape dimensioning of the passage in the container structure in relation to the outlet nozzle, or by a separate device, for example by means of added fastening components. It has been found that the outlet nozzle fixed to the dimensionally stable container structure offers protection against sensitive joints, such as welds, upstream of the outlet nozzle on the inner lining. In an imprudent actuation of the discharge device, in particular when connecting or disconnecting a discharge device to the outlet, the actuating forces are derived via the outlet to the container structure and injury to the sensitive inner lining is prevented.

Vorzugsweise sind die Klemmflügel gleichmäßig um den Außenumfang des Auslassstutzens angeordnet, um den Auslassstutzen vollumfänglich gleichmäßig zu halten. Die Haltekräfte werden insbesondere durch elastische Verformung der Klemmflügel realisiert. Der Auslassstutzen ist durch die elastische Deformationsrückstellkraft der Klemmflügel fixiert.In a preferred embodiment of the invention, the passage is formed in a wall or floor, such as a bottom plate, of the container structure.

Die wenigstens zwei sandwichartig übereinander angeordneten, vorzugsweise Kartonagen-, Platten 27, 29 bilden eine Doppelwand- oder Doppelbodenstruktur und liegen auf der Palette 59 auf.The at least two sandwiched, preferably Kartonagen-, plates 27, 29 form a double-wall or raised floor structure and are on the pallet 59 on.

Innenseitig begrenzt die Behälterstruktur 3 einen Baustoffaufnahmeraum 5. Der Baustoffaufnahmeraum 5 ist mit einer baustoffdichten, insbesondere fluiddichten, insbesondere gasdichten, Innenauskleidung 31 versehen, innerhalb der der Baustoff gelagert ist. Die Innenauskleidung 31 kann als Beschichtung auf einer Innenwand der Behälterstruktur 3 aufgebracht sein oder durch einen in den Baustoffaufnahmeraum 5 eingehängten oder eingelegten geschlossenen Beutel oder Sack, insbesondere eine Folie gebildet werden.On the inside, the container structure 3 limits a building material receiving space 5. The building material receiving space 5 is provided with a building material-tight, in particular fluid-tight, in particular gas-tight, inner lining 31, within which the building material is stored. The inner lining 31 can be applied as a coating on an inner wall of the container structure 3 or can be formed by a closed bag or bag, in particular a film, suspended or inserted into the building material receiving space 5.

Die Behälterstruktur 3 weist zur bodenseitigen Begrenzung des Baustoffaufnahmeraums 5 eine aus Kartonagen gebildete trichter- oder pyramidenförmige Auflage 13 auf, die einen Sammelbereich für den Baustoff bildet und bodenseitig in einen mittig relativ zur Aufstandsfläche des Behälters 1 angeordneten Auslass mündet. Vorzugsweise wird die Auflage 13 durch nach innen in Richtung des Auslasses geneigte Schrägplatten 15 gebildet. Der Auslass ist als kreisrunde durchgängige Materialaussparung, insbesondere als Durchgang 21 durch die Kartonagenplatten, insbesondere in einer tiefsten Stelle in der Bodenplatte, der Behälterstruktur 3 realisiert, wobei auch weitere Formen des Durchgangs 21 denkbar sind.The container structure 3 has, for the bottom-side boundary of the building material receiving space 5, a funnel-shaped or pyramid-shaped support 13 formed from cardboard, which forms a collection area for the building material and opens on the bottom side into an outlet arranged centrally relative to the footprint of the container 1. Preferably, the support 13 is formed by inclined inwardly in the direction of the outlet inclined plates 15. The outlet is realized as a circular continuous material recess, in particular as a passage 21 through the cardboard plates, in particular in a lowest point in the base plate, the container structure 3, wherein other shapes of the passage 21 are conceivable.

Wie aus Figur 2 ersichtlich, weist die Behälterstruktur 3 eine insbesondere trichterförmige Auflage 13 für die Innenauskleidung 31 auf und ist an zwei, in einer horizontalen Ebene geschlossen ringförmig umlaufenden Stützabschnitten 47, 49 entgegen der Gewichtskraft des Baustoffs abgestützt. Einer der Stützabschnitte 47, 49 wird durch eine Zwischenplatte 45 der Behälterstruktur 3 gebildet, wobei sich eine Mündungsstirnfläche der Auflage 13 auf einem der Stützabschnitte 49, 47 abstützt. Ein weiterer Stützabschnitt 47, 49 wird durch eine sich von einer Basisplatte 25, 27, 29 zur Auflage 13 erstreckenden Stützwand 41 gebildet. Die Auflage 13 für die Innenauskleidung 31 wird durch weniger als 32, insbesondere 20 oder 16 oder weniger, vorzugsweise genau 8 sich in Neigungsrichtung des Plattenabschnitts erstreckende Abstützelemente, insbesondere Stützkeile 43, insbesondere Dreiecksstege, gehalten. Dabei umfassen die Stützkeile 43 vertikale Aussparungen, so dass Stützwände 41, insbesondere Längsstege, in die Stützkeile 43 eingreifen können, um eine zusätzliche Stabilisierung der Behälterstruktur 3 zu erreichen und der Gewichtskraft des fließfähigen Baustoffs entgegenzuwirken. Die Stützabschnitte 47, 49 bilden somit Längsabstützflächen an der Unterseite der Auflage 13, wobei deren vertikale Aussparungen derart formkomplementär auf die Stützkeile 43 abgestimmt sind, dass eine formschlüssige Kopplung und Positionierung gewährleistet ist.How out FIG. 2 can be seen, the container structure 3 a particular funnel-shaped support 13 for the inner lining 31 and is supported on two, in a horizontal plane closed annular peripheral support portions 47, 49 against the weight of the building material. One of the support sections 47, 49 is formed by an intermediate plate 45 of the container structure 3, wherein a muzzle end face of the support 13 is supported on one of the support sections 49, 47. Another support section 47, 49 is formed by a support wall 41 extending from a base plate 25, 27, 29 to the support 13. The support 13 for the inner lining 31 is by less than 32, in particular 20 or 16 or less, preferably exactly 8 extending in the direction of inclination of the plate portion Supporting elements, in particular support wedges 43, in particular triangular webs held. In this case, the support wedges 43 comprise vertical recesses so that support walls 41, in particular longitudinal webs, can engage in the support wedges 43 in order to achieve additional stabilization of the container structure 3 and to counteract the weight force of the flowable building material. The support portions 47, 49 thus form Längsabstützflächen on the underside of the support 13, wherein the vertical recesses are matched to form complementary to the support wedges 43, that a positive coupling and positioning is ensured.

Ein Auslassstutzen 23 ist im Durchgang 21 als Passsitz, insbesondere Presspasssitz, wobei insbesondere ein Innendurchmesser des Durchgangs 21 vor Montage kleiner als ein Außendurchmesser des Auslassstutzens 23 ist, angeordnet. Der Auslassstutzen 23 ist an einer Basisplatte 25 mittels eines Haftvermittlers, wie Klebstoff, befestigt. Die Basisplatte 25 weist eine Doppelwand- oder Doppelbodenstruktur auf, die aus wenigstens zwei sandwichartig übereinander angeordneten Platten 27, 29 besteht. Gemäß einer ersten Ausführungsform ist der Auslassstutzen 23 an der Basisplatte 25 durch elastische Haltekräfte befestigt, wobei insbesondere die Haltekräfte radial bezüglich der Durchgangsrichtung und/oder entgegen der Gewichtskraft des Baustoffs wirken. Dabei weisen die Platten 27, 29 wenigstens zwei, vorzugsweise vier, sechs, acht, zwölf oder 16 vollumfänglich und gleichmäßig am Auslassstutzen 23 verteilte Klemmflügel 26 auf, die die elastische Haltekraft bilden und somit den Auslassstutzen 23 befestigen. Die Klemmflügel 26 werden bei der Montage des Auslassstutzens 23 elastisch deformiert und wirken mithilfe der dadurch gebildeten Deformationsrückstellkraft der Gewichtskraft des Auslassstutzens 23 und des fließfähigen Baustoffs entgegen. An einem freien Stutzenabschnitt 24, insbesondere dem unteren Abschnitt, weist der Auslassstutzen 23 ein Gewinde zum Anschließen einer Auslassleitung (nicht dargestellt), die zum Beispiel mit einer Pumpe verbindbar ist, sowie einen insbesondere gewindefreien Befestigungsabschnitt auf, der in Durchgangsrichtung unmittelbar an das Gewinde anschließt. Weiter können an dem Auslassstutzen 23 sich insbesondere radial relativ zum Durchgang erstreckende Formschlussvorsprünge und/oder -aussparungen (nicht näher dargestellt) in vorzugsweise formkomplementäre Formschlussvorsprünge und/oder -aussparungen (nicht dargestellt) der Basisplatte 25 eingreifen.An outlet 23 is in the passage 21 as a snug fit, in particular press-fit, in particular an inner diameter of the passage 21 prior to assembly is smaller than an outer diameter of the outlet 23 is arranged. The outlet port 23 is attached to a base plate 25 by means of a primer such as adhesive. The base plate 25 has a double-walled or raised floor structure consisting of at least two plates 27, 29 sandwiched one on top of the other. According to a first embodiment, the outlet nozzle 23 is attached to the base plate 25 by elastic holding forces, wherein in particular the holding forces act radially with respect to the passage direction and / or against the weight of the building material. In this case, the plates 27, 29 at least two, preferably four, six, eight, twelve or 16 fully and uniformly on the outlet port 23 distributed clamping wings 26 which form the elastic holding force and thus secure the outlet 23. The clamping wings 26 are elastically deformed during assembly of the outlet nozzle 23 and counteract with the aid of the deformation restoring force formed thereby the weight of the outlet nozzle 23 and the flowable building material. At a free nozzle portion 24, in particular the lower portion, the outlet nozzle 23 has a thread for connecting an outlet line (not shown), which is connectable, for example, with a pump, and a particular thread-free mounting portion, which connects directly in the passage direction to the thread , Further, at the outlet port 23 in particular radially relative to the passage extending positive locking projections and / or recesses (not shown in detail) in preferably complementary form-fitting form-fitting projections and / or recesses (not shown) of the base plate 25 engage.

Der Auslassstutzen 23 wird durch die innerhalb der Behälterstruktur 3 bewegliche Zwischenplatte 45, die vorzugsweise als Ringverstärkung aus Kartonagen ausgebildet ist und relativ zum Durchgang 21 größer dimensioniert und konzentrisch ausgerichtet ist sowie in der Stützwand 41 verschieblich angeordnet ist, in einem positionssichernden Kontakt gehalten. Die Verstärkungsplatte 45 ist innerhalb der Behälterstruktur 3 derart beweglich, dass ein Rand der Materialausnehmung in einen positionssichernden Verklemm-Eingriff mit dem Auslassstutzen 23 bringbar ist. Die Ringverstärkung 45 verlängert den Führungseingriffsbereich an dem Auslassstutzen in axialer Richtung und verbessert somit die Positionsgenauigkeit. Wie aus Figur 2 ersichtlich, steht die Verstärkungsplatte 45 bodenseitig mit der Basisplatte 25 und behältereingangsseitig mit wenigstens einem Stützkeil 43 sowie der Auflage 13 in Kontakt. Dabei weisen die Stützkeile 43 formkomplementäre horizontale Aussparungen auf, um die Verstärkungsplatte 45 aufzunehmen und in ihrer horizontalen Beweglichkeit einzuschränken.The outlet port 23 is formed by the movable within the container structure 3 intermediate plate 45, which is preferably formed as a ring reinforcement of cardboard and relative larger dimensioned to the passage 21 and is concentrically aligned and slidably disposed in the support wall 41, held in a position-locking contact. The reinforcing plate 45 is movable within the container structure 3 such that an edge of the material recess can be brought into a position-securing clamping engagement with the outlet nozzle 23. The ring reinforcement 45 extends the guide engagement portion on the outlet port in the axial direction and thus improves the positional accuracy. How out FIG. 2 can be seen, the reinforcing plate 45 is the bottom side with the base plate 25 and the holder input side with at least one support wedge 43 and the support 13 in contact. In this case, the support wedges 43 form complementary horizontal recesses to accommodate the reinforcing plate 45 and restrict their horizontal mobility.

Die Auflage 13 für die Innenauskleidung 31 stützt sich durchgangsseitig an einer Basisplatte 25 ab, wobei zwischen der Auflage 13 und der Innenauskleidung 31 eine Auskleidungsverstärkung, wie ein Folienring 39, angeordnet ist, die vorzugsweise an dem Auslassstutzen 23 voll umfangsumlaufend und insbesondere fluiddicht befestigt, insbesondere angeschweißt ist.The support 13 for the inner lining 31 is supported on the passage side on a base plate 25, wherein between the support 13 and the inner lining 31, a lining reinforcement, such as a film ring 39 is arranged, which is preferably attached to the outlet port 23 fully circumferentially and in particular fluid-tight, in particular is welded.

In Figur 3 ist eine alternative Ausführungsform eines Einwegbehälters 1 abgebildet, die sich im Wesentlichen durch die Stützbasis 22, welche genauer in Figur 4 dargestellt ist, der Auflage sowie des fließfähigen Baustoffs unterscheidet.In FIG. 3 an alternative embodiment of a disposable container 1 is shown, which essentially by the support base 22, which in more detail in FIG. 4 is shown, the edition and the flowable building material is different.

Laschen 37 am offenen Ende des Umkartons 11 können zur zusätzlichen Sicherung des Inhalts vor dem Verschließen mit dem Deckel 7 nach innen gebogen werden. An einer der Seitenflächen des Umkartons 11 ist eine Aussparung 51 vorgesehen, die ein Anschließen einer Auslassleitung (nicht dargestellt) an den Auslassstutzen 23 zur Entnahme des fließfähigen Baustoffs ermöglicht.Lugs 37 at the open end of the outer carton 11 can be bent inward for additional securing of the contents before closing with the lid 7. On one of the side surfaces of the outer carton 11, a recess 51 is provided, which allows a connection of an outlet (not shown) to the outlet 23 for removal of the flowable building material.

Die quaderförmige Stützbasis 22 aus Figur 4, welche auf einer Palette 59, vorzugsweise einer Europalette, aufliegt, ist vorzugsweise aus Kartonagenmaterial gebildet und umfasst nach innen faltbare Schrägwände 35, die derart nach innen geneigt sind, dass sie dieselbe Neigung wie die Schrägplatten 15 der Auflage 13 besitzen. Die Schrägwände 35 dienen damit der Abstützung der Gewichtskraft des fließfähigen Baustoffs und der Auflage 13 und bilden im zentralen Bereich einen vorzugsweise formgleichen Durchgang wie den Durchgang 21, durch den der fließfähige Baustoff über den Auslassstutzen 23 mithilfe einer Entnahmevorrichtung (nicht dargestellt) entnommen werden kann.The cuboid support base 22 from FIG. 4 which rests on a pallet 59, preferably a Euro pallet, is preferably formed of cardboard material and includes inwardly foldable inclined walls 35 which are inclined inwards so that they have the same inclination as the inclined plates 15 of the support 13. The inclined walls 35 thus serve to support the weight of the flowable building material and the support 13 and form in the central region a preferably identical passage as the passage 21, through which the flowable building material via the outlet port 23 by means of a removal device (not shown) can be removed.

Bevor die Schrägwände 35 der Stützbasis 22 in ihre Endposition gebracht werden, werden Abstützelemente, wie Trichterpolster 53, in die Stützbasis 22 eingeschoben. Diese liegen auf der Oberfläche der Palette 59, vorzugsweise auf einer Platte 27, 29, 45 auf. Zwei bündig aufeinandergestellte, insbesondere zusammengeklebte, Trichterpolster 53 stellen jeweils ein Trichterpolsterpaar dar, wobei jeweils zwei Trichterpolsterpaare eine Auflage für eine Schrägwand 35 bilden. Ein erstes Trichterpolster 53 eines Trichterpolsterpaares weist dabei eine Grundform eines gleichseitigen Dreiecks auf, während ein zweites Trichterpolster 53 die Grundform eines rechtwinkligen Dreiecks aufweist. Die Dimensionen der Trichterpolster 53 sind dabei derart aufeinander abgestimmt, dass die Hypotenuse des gleichseitigen Dreiecks gleich lang wie die Schenkelseiten des gleichseitigen Dreiecks ist. Im montierten Zustand weist ein Trichterpolsterpaar somit eine trapezförmige Struktur auf, wobei eine geneigte Seite, welche dieselbe Neigung wie die Schrägplatten 15 und die Schrägwände 35 besitzt, im montierten Zustand nach innen zeigt. Ein Trichterpolster 53 besteht vorzugsweise aus einer einstückigen Kartonageplatte, die zu einem dreieckförmigen Prisma gefaltet und vorzugsweise mittels eines Haftvermittlers wie, wie Klebstoff verklebt wird. Alternativ kann auch eine Kartonageplatte verwendet werden, die zu einem trapezförmigen Trichterpolster gefaltet werden kann.Before the inclined walls 35 of the support base 22 are brought into their end position, support elements, such as funnel pads 53, are inserted into the support base 22. These lie on the surface of the pallet 59, preferably on a plate 27, 29, 45. Two aligned, in particular glued together, funnel pads 53 each represent a funnel pad pair, with two pairs of funnel pads forming a support for a sloping wall 35. A first funnel pad 53 of a funnel pad pair has a basic shape of an equilateral triangle, while a second funnel pad 53 has the basic shape of a right-angled triangle. The dimensions of the funnel pad 53 are matched to one another such that the hypotenuse of the equilateral triangle is the same length as the leg sides of the equilateral triangle. When assembled, a funnel pad pair thus has a trapezoidal structure, with a sloped side having the same inclination as the slant plates 15 and the slant walls 35 facing inward when assembled. A funnel pad 53 preferably consists of a one-piece cardboard board, which is folded into a triangular prism and preferably glued by means of a bonding agent such as adhesive. Alternatively, a cardboard plate can be used which can be folded into a trapezoidal funnel cushion.

Des Weiteren werden zwei im Querschnitt u-förmige Stützwände 55 zur Abstützung der vertikalen Wände des Trichterunterteils in die Stützbasis 22 eingesetzt. Alternativ können auch beispielsweise vier im Querschnitt 1-förmige Stützwände 55 verwendet werden.Further, two cross-sectionally U-shaped support walls 55 for supporting the vertical walls of the funnel base are inserted into the support base 22. Alternatively, for example, four in cross-section 1-shaped support walls 55 may be used.
