Description

Die Erfindung bezieht sich auf einen Isolierbehälter, vorzugsweise in Form einer bauchig gewölbten FaBattrappe, für Getränke, insbesondere Bier, enthaltende Dosen mit einer Kapazität von mehreren Litern, wobei der aus einem Mantel und einem Boden bestehende lsolierbehälter an seiner Oberseite offen ist und eine eingesetzte Dose an ihrem oberen Rand mit geringem Spiel umschließt.The invention relates to an insulated container, preferably in the form of a bulbous, curved FaB dummy, for cans containing beverages, in particular beer, with a capacity of several liters, the insulating container consisting of a jacket and a base being open at the top and an inserted can encloses with little play at its upper edge.

Der Bierkonsum aus groBen Dosen mit Inhalten von 3,8 oder 4,0 oder 5,0 Liter ist weit verbreitet und setzt sich immer mehr durch. Die Dose wird meist in einen lsolierbehälter eingesetzt, der als FaBattrappe ausgebildet ist. An der freiliegenden Oberseite wird an der Dose eine Zapfarmatur angebracht, die eine Kohlensäurepatrone enthält, so daß der Doseninhalt unter Druck gesetzt werden kann und dadurch das Bier nach oben aus der Dose herausgedrückt wird. Die Dosen werden in einem Kühlschrank aufbewahrt, was bei der angegebenen Dosengröße noch gut möglich ist. Der lsolierbehälter bewirkt, daß das im Kühlschrank abgekühlte Bier (oder sonstige Getränk) noch mehrere Stunden kühl bleibt.Beer consumption from large cans with contents of 3.8 or 4.0 or 5.0 liters is widespread and is becoming increasingly popular. The can is usually inserted into an insulating container which is designed as a dummy dummy. On the exposed top, a tap fitting is attached to the can, which contains a carbon dioxide cartridge, so that the contents of the can can be pressurized, thereby pushing the beer out of the can. The cans are stored in a refrigerator, which is still possible with the specified can size. The insulating container ensures that the beer (or other beverage) cooled in the refrigerator remains cool for several hours.

Bekannt (DE-U- 67 52193) ist ein Isoliermantel, an den ein Boden angeformt ist. Die Dosen werden in diesen lsoliermantel von oben her eingesetzf. Die lichte Weite der oberen Öffnung ist an eine bestimmte Dosengröße angepaßt. Wenn ein größerer Spalt zwischen Öffnung und Dose vermieden werden soll, können nur zylindrische Dosen einer bestimmten Größe, z.B. 3,8-Liter-Dosen, in den Kühlmantel eingesetzt werden, nicht jedoch Dosen mit verschiedenen Größen, z.B. 3,8-Liter-Dosen und 5-Liter-Dosen.Known (DE-U-67 52193) is an insulating jacket to which a base is molded. The cans are inserted into this insulating jacket from above. The clear width of the upper opening is adapted to a certain can size. If a larger gap between the opening and the can is to be avoided, only cylindrical cans of a certain size, e.g. 3.8 liter cans to be used in the cooling jacket, but not cans with different sizes, e.g. 3.8 liter cans and 5 liter cans.

Bekannt ist auch ein Isolierbehälter zur Aufnahme einer Spirituosenflasche (CH-A-502 243), der in seinem oberen Bereich zur Anpassung an die Form der Flasche eingezogen ist und der einen lösbaren Boden aufweist. Die kühlzuhaltende Flasche wird bei abgenommenem Boden in den Isolierbehälter eingeschoben, wonach der Boden am Behältermantel befestigt wird. Dieser bekannte Isolierbehälter ist nur für die spezielle Flaschenform und FlaschengröBe geeignet, für die er bestimmt ist.Also known is an insulated container for holding a liquor bottle (CH-A-502 243), which is drawn in in its upper region to adapt to the shape of the bottle and which has a detachable bottom. The bottle to be kept cool is pushed into the insulated container with the bottom removed, after which the bottom is attached to the container jacket. This well-known insulated container is only suitable for the special bottle shape and bottle size for which it is intended.

Schließlich Ist auch ein Isolierbehälter bekannt (DE-A-2 018 018), der im Prinzip demjenigen gleicht, der in dem zuvor abgehandelten Dokument (CH-A-502243) beschrieben ist. Zur Anpassung an verschieden dicke Flaschenhälse ist in einer oberen, vom Flaschenhals durchragten Öffnung des lsolierbehälters eine elastische Dichtung, z.B. aus Schaumgummi, angeordnet. Der lsolierbehälter hat jedoch keine Mittel, die es gestatten, Dosen oder andere Gefäße verschiedener Höhe so einsetzen zu können, daß ihre oberen Ränder auf gleicher Höhe liegen.Finally, an insulated container is also known (DE-A-2 018 018), which in principle resembles that described in the previously dealt with document (CH-A-502243). In order to adapt to bottle necks of different thickness, an elastic seal, e.g. made of foam rubber. However, the insulating container does not have any means which allow cans or other vessels of different heights to be used in such a way that their upper edges are at the same height.

Der Erfindung liegt die Aufgabe zugrunde, einen Isollerbehätter zu schaffen, der für Dosen verschiedener Größe geeignet ist, ohne daß an dem lsollerbehälter Teile ausgewechselt werden müssen. Dabei soll die obere Öffnung eng an den oberen Durchmesser der Dose angepaßt sein.The invention has for its object to provide an Isoller container that is suitable for cans of different sizes, without having to replace parts on the lsoller container. The upper opening should be closely adapted to the upper diameter of the can.

Diese Aufgabe wird bei einem Isolierbehälter der eingangs genannten Art dadurch gelöst, daß der Boden am Mantel lösbar angebracht ist, derart, daß er umkehrbar und in beiden Lagen am Mantel arretierbar ist, und auf beiden Seiten Abstützflächen für eine aufsitzende Dose aufweist, die auf der einen Seite des Bodens höher sind als auf der anderen Seite, und daß der lichte Durchmesser der unteren Öffnung größer ist als der lichte Durchmesser der oberen Öffnung.This object is achieved in an insulated container of the type mentioned in that the bottom is detachably attached to the jacket in such a way that it is reversible and can be locked in both positions on the jacket, and has support surfaces for a seated can on both sides, which on the one side of the bottom are higher than on the other side, and that the inside diameter of the lower opening is larger than the inside diameter of the upper opening.

Bei einem so ausgebildeten Isolierbehälter können größere Dosen von unten her in den Isolierbehälter eingeführt werden, nachdem der Boden abgenommen wurde. Kleinere Dosen können wie bisher schon von oben her eingesetzt werden. 3,8-Liter-Dosen, 4,0-Liter-Dosen und 5,0-Liter Dosen haben die Eigenart, daß sie an ihren oberen Enden gleiche Durchmesser haben. Die Dosen mit größerem Rauminhalt jedoch, insbesondere 5,0-Liter-Dosen, sind zur Erhöhung der Kapazität gewölbt ausgebildet, so daß der größte Durchmesser der Dose größer ist als der Durchmesser am oberen Ende der Dose. Wollte man solche Dosen von oben her einsetzen, so müßte die obere Öffnung wesentlich größer ausgeführt werden als der Durchmesser des oberen Dosenendes. Dies würde einen großen Spalt zwischen Dosenrand und oberer Offnung ergeben, was unerwünscht ist und auch den Isoliereffekt beeinträchtigt. Aufgrund des erfindungsgemäßen Einführens großer Dosen von unten her erreicht man auch bei großen Dosen einen engen Anschluß des Isolierbehälters an den oberen Rand der Dose. Der umdrehbare Deckel ermöglicht die Unterbringung verschieden hoher Dosen im gleichen Isolierbehälter, wobei bei diesen verschieden hohen Dosen das obere Abschlußblech in die Ebene des oberen Randes des Isolierbehälters zu liegen kommt. Dieser Effekt wird ohne einen Einlegeboden erreicht, der bei Einsatz höherer Dosen beiseite gelegt werden muß, sondern durch einen Deckel, der stets vorhanden ist.With an insulated container designed in this way, larger cans can be introduced into the insulated container from below after the base has been removed. As before, smaller cans can be used from above. 3.8 liter cans, 4.0 liter cans and 5.0 liter cans have the peculiarity that they have the same diameter at their upper ends. However, the cans with a larger volume, in particular 5.0 liter cans, are curved to increase the capacity, so that the largest diameter of the can is larger than the diameter at the upper end of the can. If one wanted to use such cans from above, the upper opening would have to be made much larger than the diameter of the upper end of the can. This would result in a large gap between the edge of the can and the top opening, which is undesirable and also impairs the insulating effect. Due to the inventive introduction of large cans from below, even with large cans, a tight connection of the insulating container to the upper edge of the can is achieved. The rotatable lid enables different sized cans to be accommodated in the same insulating container, the upper end plate coming to lie in the plane of the upper edge of the insulating container in these differently high cans. This effect is achieved without a shelf that has to be put aside when using higher cans, but with a cover that is always present.

Der Boden kann auf verschiedene Art und Weise befestigt werden. Besonders vorteilhaft ist ein Bajonettverschluß gemäß Anspruch 2, da sich solche Verschlüsse leicht an Kunststoffteilen herstellen lassen und ohne Hilfswerkzeug befestigbar sind.The floor can be fixed in different ways. A bayonet lock according to claim 2 is particularly advantageous, since such locks can be easily produced on plastic parts and can be fastened without auxiliary tools.

Bei der Ausführungsform des Deckels nach Anspruch 3 ändert sich auch bei Umdrehen des Deckels die Gesamthöhe des Isolierbehälters nicht, so daß dieser Isolierbehälter bei den verschiedenen Dosengrößen in die gleiche Tropfschale gestellt werden kann. Die Ausführungsform des Bodens nach Anspruch 4 bringt den Vorteil, daß das verhältnismäßig große Gewicht der Dose nicht auf den Mantel übertragen werden muß, sondern über den Boden unmittelbar auf der Standfläche abgestützt wird. Zentrierränder gemäß dem Anspruch 5 am Boden gestatten eine exakte Fixierung der Dosen auch an ihren unteren Enden und dadurch eine exakte Ausrichtung auf den Isolierbehälter. Im Boden angeordnete Grifflöcher gemäß Anspruch erleichtern das Einsetzen und Lösen des Bodens. Anstelle von Grifflöchern könnten auch andere Handhabungshilfen vorgesehen werden, z.B. Vorsprünge.In the embodiment of the lid according to claim 3, the total height of the insulating container does not change even when the lid is turned over, so that this insulating container can be placed in the same drip tray with the different can sizes. The embodiment of the floor according to claim 4 has the advantage that the relatively large weight of the can does not have to be transferred to the jacket, but is supported directly on the base over the floor. Centering edges according to claim 5 on the floor allow an exact fixation of the cans also at their lower ends and thereby an exact alignment with the insulating container. Handle holes arranged in the floor make it easier to insert and detach the floor. Instead of handle holes, other handling aids could also be provided, for example projections.

Im Anspruch 7 sind Abmessungen für den Durchmesser der oberen Öffnung und der unteren Öffnung sowie für die Nutzhöhe angegeben. Diese Abmessungen sind an genormte Dosengrößen mit Inhalten von 3,8 und 4,0 und 5,0 Liter angepaßt. Man wird selbstverständlich in Anpassung an diese genormten Dosengrößen die Durchmesser der Öffnungen so wählen, daß ein gewisses Spiel vorhanden ist und keinesfalls ein Klemmen eintreten kann.In claim 7 dimensions for the diameter of the upper opening and the lower opening and for the usable height are given. These dimensions are adapted to standard can sizes with contents of 3.8, 4.0 and 5.0 liters. Of course, in adaptation to these standardized can sizes, the diameters of the openings will be chosen so that there is a certain play and under no circumstances can jamming occur.

Wenn, was üblich und an sich bekannt ist, am oberen Ende des Kühlmantels eine horizontale ringförmige Randfläche vorhanden ist, ist es vorteilhaft, eine solche Randfläche gemäß Anspruch 8 mit Rippen abzustützen, die Führungsflächen aufweisen, die eine von unten eingesetzte Dose in die obere Öffnung leiten. Dadurch wird das Einsetzen der Dosen wesentlich erleichtert.If, as is customary and known per se, a horizontal annular edge surface is present at the upper end of the cooling jacket, it is advantageous to support such an edge surface according to claim 8 with ribs which have guide surfaces which have a can inserted from below into the upper opening conduct. This makes it much easier to insert the cans.

Der Mantel und eventuell auch der Boden bestehen gemäß Anspruch 9 vorzugsweise aus Strukturschaum. Strukturschaum hat gute Isoliereigenschaften, da der Kunststoff Hohlräume enthält. Strukturschaum hat die weitere Eigenschaft, daß die äußeren Bereiche porenfrei sind, so daß eine große Festigkeit erreicht wird und auch eine für die hygienische Pflege des Mantels geeignete Oberfläche vorhanden ist. Dies hat für den Gebrauch wesentliche Vorteile im Vergleich mit Isolierbehältern mit Einsätzen aus aufgeschäumtem Polystyrol, z.B. Styropor. Solches Material ist ein wenig fest und bröckelt im Laufe der Zeit ab. Eine Reinigung von Styropor-Teilen ist nur schwer möglich. Alle diese Nachteile sind durch die Bildung des Mantels aus Strukturschaum vermieden. Der Boden kann, da er keine nennenswerte Isolieraufgabe hat, als Kunststoffspritzteil ausgebildet werden.The jacket and possibly also the bottom preferably consist of structural foam. Structural foam has good insulating properties because the plastic contains cavities. Structural foam has the further property that the outer areas are pore-free, so that great strength is achieved and there is also a surface suitable for hygienic care of the jacket. This has significant advantages for use in comparison with insulated containers with inserts made of foamed polystyrene, e.g. Styrofoam. Such material is a little stiff and crumbles over time. Cleaning styrofoam parts is difficult. All of these disadvantages are avoided by the formation of the shell from structural foam. The floor, since it has no significant insulation task, can be designed as a molded plastic part.

Wie an sich bekannt, können am oberen Rand des Mantels Ausschnitte gemäß Anspruch 11 vorhanden sein, was die Verwendung von Zapfarmaturen mit nach unten geführtem Auslaufrohr gestattet.As is known per se, cutouts according to claim 11 may be present at the upper edge of the jacket, which allows the use of dispensing fittings with a downwardly directed outlet pipe.

Der Isolierbehälter ist insgesamt mit M bezeichnet. Innerhalb des Isolierbehälters befindet sich eine Dose 1, an der eine Zapfarmatur 2 mit nach unten geneigtem Auslaufrohr3 angeordnet ist. Der Isolierbehälter steht in einer Vertiefung 4 einer Tropfschale 5.

The nature of the insulating container M will be considered below with reference to the other figures.

Der Isolierbehälter M besteht aus einem Mantel 6 und einem Boden 7. Der Mantel 6 ist aus Strukturschaum gefertigt. Strukturschaum hat bekanntlich die Eigenschaft, daß Wände aus Strukturschaum eine mittlere poröse Schicht und im wesentlichen porenfreie Randschichten aufweist. Dadurch haben Teile aus Strukturschaum eine gute Isolierfähigkeit und trotzdem eine hohe Festigkeit und auch eine dichte Oberfläche. Der Mantel 6 ist aus zwei gleichen Schalen zusammengesetzt, die längs vertikalen Fugen miteinander verbunden sind, vorzugsweise durch Klebung.The insulating container M consists of a jacket 6 and a bottom 7. The jacket 6 is made of structural foam. Structural foam is known to have the property that walls made of structural foam have a central porous layer and essentially pore-free edge layers. As a result, parts made of structural foam have good insulating properties and yet have high strength and a dense surface. The jacket 6 is composed of two identical shells which are connected to one another along vertical joints, preferably by gluing.

Der Mantel 6 ist als Faßattrappe ausgebildet und hat eine dementsprechend bauchige Form. An die Außenseite sind Ringe 8 bis 11 angeformt. Diese Ringe sollen Faßreifen symbolisieren. Strukturschaum eignet sich auch gut zur Imitation von Holz, so daß der Isolierbehälter M als Holzfaßattrappe ausgebildet werden kann, wie dies in Fig. 1 angedeutet ist.The jacket 6 is designed as a dummy dummy and has a correspondingly bulbous shape. Rings 8 to 11 are formed on the outside. These rings symbolize barrel hoops. Structural foam is also well suited for imitation of wood, so that the insulating container M can be designed as a dummy wooden barrel, as indicated in FIG. 1.

Der Mantel 6 hat eine obere Öffnung 12 mit einem Durchmesser d1 und eine untere Öffnung 13 mit einem Durchmesser d2. Der Durchmesser d2 ist größer als der Durchmesser d1. Die untere Öffnung 13 ist mit dem Boden 7 verschließbar, wobei zur Verriegelung ein Bajonettverschluß vorgesehen ist. Dieser Bajonettverschluß besteht aus winkelförmigen Rastvertiefungen 14 an der Innenseite des Mantels 6 und aus Vorsprüngen 15 (siehe Fig. 5) am Boden 7. Die winkelförmigen Rastvertiefungen 14 haben einen breiten Einführungsteil 14a und einen schmalen Verriegelungsteil14b. Die Breite des Einführungsteiles 14a ist gleich der Breite der Vorsprünge 15, während die Breite der Rastvertiefungen 14 gleich der Dicke der Vorsprünge 15 ist. Wie man aus den Schnitten nach den Fig. 2 und 4 ersehen kann, befinden sich die Vorsprünge 15 in der Höhenmitte des Bodens 7. Insgesamt sind vier Rastvertiefungen 14 vorhanden, wobei an jeder Hälfte des Mantels zwei solcher Rastvertiefungen angeordnet sind. Bei dieser Art der Anordnung können die beiden Hälften des Mantels spiegelbildlich ausgebildet werden, so daß man nur eine Ausschäumform für eine Hälfte benötigt, um einen kompletten Mantel herzustellen.The jacket 6 has an upper opening 12 with a diameter d 1 and a lower opening 13 with a diameter d 2 . The diameter d 2 is larger than the diameter d1. The lower opening 13 can be closed with the base 7, a bayonet lock being provided for locking. This bayonet catch consists of angular locking recesses 14 on the inside of the jacket 6 and of projections 15 (see FIG. 5) on the bottom 7. The angular locking recesses 14 have a wide insertion part 14a and a narrow locking part 14b. The width of the insertion part 14a is equal to the width of the projections 15, while the width of the locking recesses 14 is equal to the thickness of the projections 15. As can be seen from the sections according to FIGS. 2 and 4, the projections 15 are located in the middle of the height of the bottom 7. A total of four latching depressions 14 are present, two such latching depressions being arranged on each half of the jacket. With this type of arrangement, the two halves of the jacket can be formed in mirror image, so that only one foam-out mold is required for one half to produce a complete jacket.

Der Boden 7 hat zwei Abstützflächen, nämlich eine schmale ringförmige Abstützfläche 16 und eine kreisförmige Abstützfläche 17. Die Abstützfläche 16 ist von einem Zentrierrand 18 umgeben, der den Durchmesser d3 aufweist. Die Abstützfläche 17 ist von einem Zentrierrand 19 umgeben, der den Durchmesser d4 hat. Der Höhenabstand h1 der Abstützfläche 16 vom Bodenrand 20 ist größer als der Höhenabstand h2 der Abstützfläche 17 vom Bodenrand 21.The bottom 7 has two support surfaces, namely a narrow annular support surface 16 and a circular support surface 17. The support surface 16 is surrounded by a centering edge 18 which has the diameter d 3 . The support surface 17 is surrounded by a centering edge 19 which has the diameter d 4 . The height distance h 1 of the support surface 16 from the bottom edge 20 is greater than the height distance h 2 of the support surface 17 from the bottom edge 21.

Die Abstützfläche 17 befindet sich an einer Wand 22, in der Grifflöcher 23 und 24 angeordnet sind. Diese Wand ist von einem Ring 25 umgeben, der seinerseits an einem Ring 26 sitzt.The support surface 17 is located on a wall 22 in which handle holes 23 and 24 are arranged. This wall is surrounded by a ring 25, which in turn is seated on a ring 26.

Der Boden 7 kann als Kunststoff-Spritzteil ausgebildet sein. Vorzugsweise ist in die Wand 22 eine Beschriftung eingeformt. Auf der unteren Wandfläche22a befindet sich z.B. die Beschriftung « 4 Liter und auf der Abstützfläehe 17 die Beschriftung «5 Liter». Ferner können Drehrichtungspfeile angebracht sein, die die Drehbewegungen für das Lösen und für das Verriegeln des Bodens 7 angeben (siehe Fig. 5).The bottom 7 can be designed as a plastic injection molded part. A label is preferably formed in the wall 22. On the lower wall surface 22a there is e.g. the lettering "4 liters and on the support surface 17 the lettering" 5 liters ". Furthermore, directional arrows can be attached, which indicate the rotary movements for releasing and for locking the base 7 (see FIG. 5).

Am oberen Ende des Mantels 6 befinden sich einander diametral gegenüberliegend Ausschnitte 27 und 28 für den Durchgang eines Zapfrohres. Die obere Öffnung 12 ist von einer horizontalen Randfläche 29 umgeben, die durch Rippen abgestützt sein kann. Auch die Ausschnitte 27, 28 sind durch Rippen 30, 31 abgestützt, deren Endflächen (Anlaufflächen) 30a und 31a ohne Stufe in den Rand der oberen Öffnung 12 auslaufen. An der Innenseite des Manteis 6 befindet sich eine kreisrunde Erhebung 32, in die ein Firmenemblem 33 eingeformt ist.At the upper end of the jacket 6 there are diametrically opposite cutouts 27 and 28 for the passage of a nozzle. The upper opening 12 is surrounded by a horizontal edge surface 29 which can be supported by ribs. The cutouts 27, 28 are also supported by ribs 30, 31, the end surfaces (contact surfaces) 30a and 31a of which run out without a step into the edge of the upper opening 12. On the inside of the manteis 6 there is a circular elevation 32 into which a company emblem 33 is molded.

Der Isolierbehälter wird wie folgt gebraucht.The insulated container is used as follows.

Wenn kleinere Dosen, also z.B. 4-Litter-Dosen 1 verbraucht werden sollen, wird der Boden 7 so eingesetzt, wie in Fig. 2 dargestellt, d.h. derart, daß die Abstützfläche 17 nach oben gewendet ist. Die Dose 1 wird von oben her in den Mantel 6 eingeführt. Sie zentriert sich mit ihrem unteren Rand an dem Zentrierrand 19 des Bodens. Ihre Oberseite 1a befindet sich dann auf dem Niveau des oberen Randes des Mantels 6. Der Durchmesser der oberen Öffnung 12 ist an dem genormten Durchmesser der Dose 1 so angepaßt, daß kein nennenswerter Spalt zwischen Dose und oberer horizontaler Randfläche 29 vorhanden ist.If smaller doses, e.g. 4-litter cans 1 are to be used, the bottom 7 is used as shown in Fig. 2, i.e. such that the support surface 17 is turned upwards. The can 1 is inserted into the jacket 6 from above. It is centered with its lower edge on the centering edge 19 of the base. Its upper side 1a is then at the level of the upper edge of the jacket 6. The diameter of the upper opening 12 is adapted to the standardized diameter of the can 1 so that there is no significant gap between the can and the upper horizontal edge surface 29.

Nach dem Einsetzen wird die Zapfarmatur 2 aufgesetzt. Der isolierbehälter wird in eine Tropfschale 5 gestellt, wonach der Bierkonsum beginnen kann. Das Gewicht der Dose 1 stützt sich über den Boden 7 unmittelbar auf der Tropfschale 5 ab, d.h. der Mantel 6 wird mit dem Gewicht der Dose nicht belastet. Dies erreicht man dadurch, daß der untere Rand 20 des Bodens in der gleichen Ebene oder noch ein wenig tiefer liegt als der untere Rand des Mantels 6.After insertion, the tap fitting 2 is put on. The insulated container is placed in a drip tray 5, after which beer consumption can begin. The weight of the can 1 is supported directly on the drip tray 5 via the base 7, i.e. the jacket 6 is not loaded with the weight of the can. This is achieved in that the lower edge 20 of the base lies in the same plane or a little lower than the lower edge of the jacket 6.

Die Dose 1 wird in gut gekühltem Zustand eingesetzt. Da der aus Strukturschaum bestehende Mantel 6 gut isoliert, bleibt das Bier mehrere Stunden kalt.Box 1 is used in a well-cooled state. Since the jacket 6 made of structural foam insulates well, the beer remains cold for several hours.

In Fig. 4 ist der Zustand gezeigt, wenn eine große Dose, z.B. eine 5-Liter-Dose 34, in den Mantel 6 eingesetzt ist. In diesem Fall ist der Boden 7 gegenüber der Situation nach Fig. 2 umgedreht, d.h. in diesem Fall ist die schmale Abstützfläche 16 nach oben gewendet. Diese Fläche liegt tiefer als die Abstützfläche 17 bei der Situation nach Fig. 2, so daß auch eine etwas längere Dose so untergebracht werden kann, daß ihre Oberseite 34a jedenfalls auf Höhe des oberen Randes des Mantels 6 liegt.In Fig. 4 the state is shown when a large can, e.g. a 5 liter can 34 is inserted into the jacket 6. In this case, the bottom 7 has been turned over in relation to the situation according to FIG. in this case the narrow support surface 16 is turned upwards. This surface lies deeper than the support surface 17 in the situation according to FIG. 2, so that a somewhat longer box can also be accommodated in such a way that its top side 34a is in any case at the level of the upper edge of the jacket 6.

Die Dose 34 ist bauchig gewölbt, jedoch ist ihr oberer Durchmesser gleich wie der obere Durchmesser der kleineren Dose 1. Der untere Durchmesser d5 der Dose 34 ist größer als der obere Durchmesser und auch größer als der Durchmesser d1 der oberen Öffnung 12. Im übrigen ist der größte Durchmesser der Dose im Bereich der Wölbung des Dosenmantels 34b vorhanden. Die Dose kann deshalb nicht von oben her durch die Öffnung 12 eingeführt werden. Sie wird bei gelöstem Boden 7 von unten her eingeführt. Dank der Anlaufflächen 30a und 31 a (siehe Fig. 2) wird die Dose in den Bereich der oberen Öffnung 12 geführt. Wenn die Dose eingeführt ist, wird der Boden 7 aufgesetzt und durch eine Drehbewegung in Richtung des Pfeiles « anziehen » (siehe Fig. 5) verriegelt. Das Anziehen und Lösen des Bodens ist bequem möglich, indem mit Daumen und Zeigefinger oder Mittelfinger in die Grifflöcher 23 und 24 eingegriffen wird.The can 34 is bulged, but its upper diameter is the same as the upper diameter of the smaller can 1. The lower diameter d 5 of the can 34 is larger than the upper diameter and also larger than the diameter d 1 of the upper opening 12. Im the largest diameter of the can is present in the region of the curvature of the can jacket 34b. The can therefore cannot be inserted from above through the opening 12. It is inserted from below with the floor 7 detached. Thanks to the contact surfaces 30a and 31a (see FIG. 2), the can is guided into the area of the upper opening 12. When the can is inserted, the base 7 is put on and “tightened” by a rotary movement in the direction of the arrow (see FIG. 5). Tightening and loosening of the floor is easily possible by engaging the finger holes 23 and 24 with your thumb and index finger or middle finger.
