Description

Die Erfindung betrifft eine Kühlbox zum Kühlhalten von mit Flüssigkeit gefüllten, insbesondere zylindrischen Behältern bestehend aus einem topfförmigen Unterteil, in dem mindestens ein an den Seitenwänden der Behälter angeordnetes Kühlelement auswechselbar eingesetzt ist, und aus einem darauf aufsetzbaren Deckel, zwischen dem und dem Boden des Unterteils das Kühlelement fixiert ist und der im Bereich der die Deckeloberkante der Kühlbox überragenden Behälter ausgespart ist.The invention relates to a cool box for keeping liquid-filled, in particular cylindrical containers cool, consisting of a pot-shaped lower part, in which at least one cooling element arranged on the side walls of the containers is interchangeably inserted, and of a cover which can be placed thereon, between the and the bottom of the lower part the cooling element is fixed and is recessed in the area of the container projecting above the top edge of the cool box.

Bei einer bekannten Kühlbox der eingangs genannten Art hat das topfförmige Unterteil einen kreisförmigen Querschnitt und einen kreisförmigen Deckel. Der Deckel weist für jeden in die Kühlbox einstellbaren und zu kühlenden kreiszylindrischen Behälter eine separate kreisförmige Aussparung gleicher Größe auf. Diese Aussparungen sind in einem konzentrischen Kreis um die Mittelsenkrechte des topfförmigen Unterteils angeordnet. In diese bekannte Kühlbox wird ein einziges Kühlelement zentral derart in die Kühlbox hineingestellt, daß es sich vom Boden des Unterteils des bis zur Unterseite des Deckels erstreckt und die eingestellten Behälter das Kühlelement umgeben. Die Seitenflächen des Kühlelementes weisen entlang ihrer gesamten Höhe Einbuchtungen auf, dergestalt, daß sich mit ihren Außenwänden die zylindrischen Behälter an die Einbuchtungen anschmiegen.In a known cool box of the type mentioned, the pot-shaped lower part has a circular cross section and a circular lid. The lid has a separate circular recess of the same size for each circular cylindrical container that can be set and cooled in the cool box. These recesses are arranged in a concentric circle around the central perpendicular of the pot-shaped lower part. In this known cool box, a single cooling element is placed centrally in the cool box in such a way that it extends from the bottom of the lower part which extends to the underside of the lid and the set containers surround the cooling element. The side surfaces of the cooling element have indentations along their entire height, in such a way that the cylindrical containers nestle against the indentations with their outer walls.

An diesen bekannten Kühlboxen ist nachteilig, daß die in einem konzentrischen Kreis und mit einem Abstand zueinander angeordneten Behälter viel Platz beanspruchen und viel Freiraum verbleibt, durch den warme Umgebungsluft an den Behältern vorbeistreicht, die die Behälter schnell erwärmt. Ferner ist nachteilig, daß die für jeden Behälter separat vorgesehene Aussparung lediglich für die Anordnung von zylindrischen Behältern mit nahezu gleichem Durchmesser der Bodenfläche geeignet ist, da zu große Behälter nicht in die Aussparungen passen und Behälter mit kleinerem Durchmesser nicht mit dem zentral angeordneten Kühlelement in Kontakt treten, wodurch sich eine unzureichende Kühlwirkung ergibt.A disadvantage of these known coolers is that the containers arranged in a concentric circle and at a distance from one another take up a lot of space and a lot of free space is left by the warm ambient air passing by the containers, which heats the containers quickly. Another disadvantage is that the recess provided separately for each container is only suitable for the arrangement of cylindrical containers with almost the same diameter of the bottom surface, since containers that are too large do not fit into the recesses and containers with a smaller diameter do not come into contact with the centrally arranged cooling element occur, resulting in an insufficient cooling effect.

Eine weitere bekannte Kühlbox unterscheidet sich von der vorgenannten bekannten Kühlbox vor allem darin, daß anstelle des zentralen Kühlelementes der Deckel als Kühlelement ausgebildet ist, indem der Deckel hohl ist und mit einer Kühlflüssigkeit gefüllt ist. Dieser Deckel stellt das einzige Kühlelement dieser Kühlbox dar und kühlt die in die Kühlbox eingebrachten zylindrischen Behälter lediglich im schmalflächigen Kontaktbereich zwischen dem Deckel und der Behälteraußenwandung.Another known cool box differs from the aforementioned known cool box mainly in that, instead of the central cooling element, the lid is designed as a cooling element in that the lid is hollow and is filled with a cooling liquid. This cover represents the only cooling element of this cool box and cools the cylindrical containers introduced into the cool box only in the narrow-area contact area between the cover and the outer wall of the container.

Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, eine Kühlbox zu schaffen, die die beschriebenen Nachteile des Standes der Technik nicht hat.The object of the present invention is to create a cool box which does not have the disadvantages of the prior art described.

Diese Aufgabe wird bei der Vorrichtung der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß das Unterteil die Form eines Prismas mit rechteckigen Seitenwänden hat, die die in hexagonal dichteste Anordnung bringbaren Behälter als Ganzes umschließt, daß an der Innenseite jeder Seitenwand des Unterteils ein plattenförmiges Kühlelement angeordnet ist, wobei diese an den Ecken des prismatischen Innenteils, zum Zwecke gegenseitigen Abstützens derart profiliert sind, daß ihre Bewegung in den Innenraum des Unterteils nicht möglich ist, und daß der Deckel eine einzige zentrale Aussparung aufweist, deren Randabschnitte parallel zu den Seitenwänden verlaufen.This object is achieved in the device of the type mentioned in the introduction in that the lower part has the shape of a prism with rectangular side walls, which encloses the container which can be brought into a hexagonal closest arrangement as a whole, that a plate-shaped cooling element is arranged on the inside of each side wall of the lower part is, which are profiled at the corners of the prismatic inner part, for the purpose of mutual support, that their movement into the interior of the lower part is not possible, and that the lid has a single central recess, the edge portions of which run parallel to the side walls.

In der erfindungsgemäßen Kühlbox lassen sich unter Berücksichtigung des durch den Innenraum vorgegebenen Raumes Behälter unterschiedlicher Größe und Zahl innerhalb der einzigen zentralen Ausparung im Deckel in hexagonal dichtester Anordnung unterbringen, d.h. jeweils ein Behälter befindet sich in einer keilförmigen Mulde, die von zwei nebeneinander stehenden Behältern gebildet ist. Hierdurch verbleibt ein Minimum an Leerraum zwischen den Behältern. An der Innenseite jeder Seitenflächen ist ein plattenförmiges Kühlelement angeordnet, das mit jedem nächstliegenden zu kühlenden Behälter unmittelbar in Kontakt tritt und sowohl die unmittelbar am Kühlelement befindlichen Behälter als auch die in hinteren Reihen in hexagonaler Anordnung stehenden Behälter kühlt.In the cool box according to the invention, containers of different sizes and numbers can be accommodated within the only central recess in the lid in a hexagonally close arrangement, taking into account the space predetermined by the interior, i.e. one container each is located in a wedge-shaped trough which is formed by two containers standing next to one another. This leaves a minimum of empty space between the containers. Arranged on the inside of each side surface is a plate-shaped cooling element, which comes into direct contact with each nearest container to be cooled and cools both the containers located directly on the cooling element and the containers arranged in the rear rows in a hexagonal arrangement.

Der Vorteil dieser Lösung liegt insbesondere darin, daß eine hohe Packungsdichte der zu kühlenden Behälter erzielt wird. Hierdurch ist ein optimales Verhältnis von Kühlraum zu Kühlmittelraum bei vorgegebener Kühlboxgrundfläche erreicht. Ferner sorgt der Kontakt der Behälter für eine gleichmäßige, infolge der minimalen Konvektionsfläche zudem langsame Erwärmung aller Behälter.The advantage of this solution is, in particular, that a high packing density of the containers to be cooled is achieved. In this way, an optimal ratio of cold room to coolant room is achieved for a given cool box footprint. Furthermore, the contact of the containers ensures an even, slow due to the minimal convection area Heating of all containers.

Bevorzugt weist die Kühlbox die Grundfläche eines gleichseitigen Dreiecks auf, bei der sich die plattenförmigen Kühlelemente gegenseitig abstützen, so daß diese nicht in den Innenraum des Unterteils fallen können. Zudem sind die Kühlelemente gleich dimensioniert, so daß ein fehlerhaftes Einschieben der Kühlelemente (Verwechseln bei verschiedenartigen Kühlelementen) in das Unterteil der Kühlbox vermieden wird. Ferner können die Innenseiten der Kühlelemente Hohlkehlen aufweisen, an die sich die Außenwandungen der zu kühlenden Behälter der ersten Reihe anschmiegen, wodurch eine größere Kontaktfläche zwischen Kühlgut und Kühlelement im Vergleich zu ebenen Kühlelementen gegeben ist. Zur Verbesserung der thermischen Isolierung zwischen den Kühlelementen und den Seitenwänden des Unterteils sind vorzugsweise plattenförmige Isolierelemente zwischen den Kühlelementen und den Innenseiten der Seitenwände des Unterteils angebracht.The cool box preferably has the base of an equilateral triangle, in which the plate-shaped cooling elements are supported against one another, so that they cannot fall into the interior of the lower part. In addition, the cooling elements are dimensioned the same, so that an incorrect insertion of the cooling elements (confused with different types of cooling elements) in the lower part of the cool box is avoided. Furthermore, the inner sides of the cooling elements can have fillets against which the outer walls of the containers of the first row to be cooled nestle, as a result of which there is a larger contact area between the goods to be cooled and the cooling element in comparison to flat cooling elements. To improve the thermal insulation between the cooling elements and the side walls of the lower part, plate-shaped insulating elements are preferably provided between the cooling elements and the inner sides of the side walls of the lower part.

Weitere bevorzugte Ausgestaltungen der erfindungsgemäßen Kühlbox sind in den Unteransprüchen gekennzeichnet.Further preferred embodiments of the cool box according to the invention are characterized in the subclaims.

Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand einer nicht maßstäblich darstellenden Zeichnung näher erläutert. Es zeigen:

  • Fig. 1 eine mit Behältern gefüllte Kühlbox in perspektivischer Darstellung;
  • Fig. 2 die mit Behältern gefüllte Kühlbox gemäß Fig.1 im Horizontal-Schnitt nach Linie I-I der Fig. 1;
  • Fig. 3 die Kühlbox gemäß Fig.1 mit Deckel in Draufsicht.
An exemplary embodiment of the invention is explained in more detail below with reference to a drawing that is not to scale. Show it:
  • 1 is a perspective view of a cool box filled with containers;
  • 2 shows the cool box filled with containers according to FIG. 1 in a horizontal section along line II of FIG. 1;
  • Fig. 3, the cooler according to Figure 1 with a lid in plan view.

Die Fig. 1 zeigt eine Kühlbox 1 bestehend aus einem prismatischen, topfförmigen Unterteil 3 und einem Deckel 5. Das Unterteil 3 weist die Grundfläche eines gleichseitigen Dreiecks und zu diesem rechtwinkligen Seitenflächen 6 auf. In den Ecken, die durch die Seitenflächen 6 gebildet sind befinden sich Abstandshalter 10, die an den Innenseiten der Seitenflächen 6 befestigt sind und die mit Flüssigkeit gefüllten Kühlelemente 4 auf Abstand von den Seitenflächen 6 des Unterteils 3 halten. Im Zwischenraum zwischen den Kühlelementen 4 und den Innenseiten der Seitenflächen 6 befindet sich ein thermisch isolierender Luftspalt 11, der allerdings auch mit Isoliermaterial ausgefüllt sein kann. Die von den Abstandshaltern 10 auf Abstand gehaltenen drei plattenförmigen Kühlelemente 4 haben untereinander gleiche Abmessungen und ihre endseitigen Begrenzungsflächen verlaufen parallel zu den Winkelhalbierenden 9 der Ecken des prismatischen Unterteils 3. In dem Raum, der von den Kühlelementen 4 umschlossen ist, befinden sich drei kreiszylindrische Behälter 2 in hexagonal dichtester Anordnung, d.h. ein Behälter befindet sich in der keilförmigen Mulde, die von den beiden anderen kreiszylindrischen Behältern gebildet ist. Bei dieser Anordnung wird eine maximale Kontaktfläche zwischen den Behältern 2 untereinander sowie zwischen den Behältern 2 und den Kühlelementen 4 erzielt.1 shows a cool box 1 consisting of a prismatic, pot-shaped lower part 3 and a cover 5. The lower part 3 has the base of an equilateral triangle and side surfaces 6 which are perpendicular to it. In the corners, which are formed by the side surfaces 6, there are spacers 10, which are fastened to the inner sides of the side surfaces 6 and keep the cooling elements 4 filled with liquid at a distance from the side surfaces 6 of the lower part 3. In the space between the cooling elements 4 and the inside of the side surfaces 6 there is a thermally insulating air gap 11, which, however, can also be filled with insulating material. The three plate-shaped cooling elements 4, which are kept at a distance from one another by the spacers 10, have the same dimensions and their end faces run parallel to the bisectors 9 of the corners of the prismatic lower part 3. In the space which is surrounded by the cooling elements 4, there are three circular-cylindrical containers 2 in the hexagonally closest arrangement, ie a container is located in the wedge-shaped depression which is formed by the other two circular cylindrical containers. With this arrangement, a maximum contact area is achieved between the containers 2 with one another and between the containers 2 and the cooling elements 4.

Die Grundfläche des Deckels 5 hat die gleiche Form und die gleichen Abmessungen wie die Grundfläche des Unterteils 3. Der Deckel 5 weist eine zentrale Aussparung 7 auf, deren Ränder 8 parallel zu den Außenkanten 6′ des Deckels 5 verlaufen und im Bereich der Ecken abgerundet sind. Parallel zu den Außenkanten 6′ verlaufen Befestigungsleisten 12, die den Deckel nach Aufsetzen auf das Unterteil 3 gegenüber dem Unterteil 3 und die Kühlelemente 4 zwischen dem Boden des Unterteils 3 und dem Deckel 5 fixieren.The base of the cover 5 has the same shape and the same dimensions as the base of the lower part 3. The cover 5 has a central recess 7, the edges 8 of which run parallel to the outer edges 6 'of the cover 5 and are rounded in the corners . Parallel to the outer edges 6 'run mounting strips 12 which fix the cover after placing on the lower part 3 relative to the lower part 3 and the cooling elements 4 between the bottom of the lower part 3 and the cover 5.

Anstelle von drei Behältern lassen sich in der Kühlbox 1 auch sechs kleinere Behälter in hexagonaler Anordnung unterbringen. Auch ist es möglich, wie in Fig. 3 angedeutet, nur einen einzigen Behälter mit größerem Durchmesser unterzubringen. In jedem Fall kann bei entsprechender Dimensionierung der Behälter und/oder der Kühlbox erreicht werden, daß sie an den Kühlelementen und ggf. aneinander anliegen.Instead of three containers, six smaller containers in hexagonal arrangement can also be accommodated in the cool box 1. It is also possible, as indicated in FIG. 3, to accommodate only a single container with a larger diameter. In any case, with appropriate dimensioning of the container and / or the cool box, it can be achieved that they rest on the cooling elements and possibly on one another.
