Description

Die Erfindung betrifft einen Behälter für die Lagerung und/oder den Transport von Trockeneisteilchen, mit einem Lagerbereich, der mit thermisch isolierten Seitenwänden und einer Bodenplatte ausgerüstet ist.The invention relates to a container for the storage and / or transport of dry ice particles, having a storage area equipped with thermally insulated side walls and a bottom plate.

Trockeneisteilchen in Form von Schnee, Pellets, Nuggets, Scherben oder Scheiben werden nach ihrer Herstellung häufig in thermisch isolierten Behältern mit einer Kapazität von wenigen Kilogramm bis zu einigen Hundert Kilogramm Trockeneis gelagert und/oder transportiert. Zum Transport sind zumindest die größeren Behälter mit Rädern ausgerüstet oder lassen sich auf Fahrgestelle montieren, oder die Behälter weisen Standfüße auf, aufgrund derer sie von einem Gabelstapler untergriffen und befördert werden können. Die Wände der meist mit einem Deckel versehenen Behälter sind in der Regel aus Edelstahl oder Kunststoff, wie Styropor, expandiertem Polypropylen, Polyurethan, etc. gefertigt und/oder mit einer zusätzlichen Isolierschicht, beispielsweise aus geschäumtem Kunststoff, ausgerüstet. Beispiele für Trockeneisbehälter nach dem Stande der Technik finden sich etwa im Firmenprospekt "Trockeneislagerung" der ASCO Kohlensäure AG, Romanshom (Schweiz), der im Internet unter deren Adresse "www.asooco2.com" abrufbar ist.Dry ice particles in the form of snow, pellets, nuggets, cullet or slices are often stored and / or transported in thermally insulated containers with a capacity of a few kilograms to a few hundred kilograms of dry ice after their production. For transport, at least the larger containers are equipped with wheels or can be mounted on chassis, or the containers have feet, due to which they can be attacked and transported by a forklift. The walls of the container usually provided with a lid are usually made of stainless steel or plastic, such as Styrofoam, expanded polypropylene, polyurethane, etc. and / or with an additional insulating layer, for example, made of foamed plastic equipped. Examples of dry ice containers according to the state of the art can be found, for example, in the company brochure "dry ice storage" of ASCO Kohlensäure AG, Romanshom (Switzerland), which is available on the Internet at their address "www.asooco2.com".

Die Trockeneisteilchen werden im Behälter an ihren Einsatzort verbracht und dort in der Regel manuell entnommen. Je nach Größe und Tiefe des Behälters ist dies für den Benutzer nicht ungefährlich, da er sich dabei unter Umständen über den mit gasförmigem Kohlendioxid angefüllten Behälter oder sogar in diesen hinein beugen muss.The Trockeneisteilchen be spent in the container at their place of use and there usually removed manually. Depending on the size and depth of the container, this is not dangerous for the user, since he may have to bend over the container filled with gaseous carbon dioxide or even into it.

Der Erfindung liegt daher die Aufgabe zu Grunde, einen Behälter zum Lagern und/oder Transportieren von Trockeneisteilchen zu schaffen, dessen Handhabung für einen Benutzer erleichtert und bei dessen Benutzung die gesundheitliche Gefährdung reduziert ist.The invention is therefore based on the object to provide a container for storing and / or transporting Trockeneisteilchen, facilitates its handling for a user and the health risk is reduced in its use.

Gelöst wird diese Aufgabe bei einem Behälter der eingangs genannten Art und Zweckbestimmung dadurch, dass die Bodenplatte vertikal verschiebbar gegenüber den Seitenwänden angeordnet ist.This object is achieved in a container of the type and purpose mentioned in the fact that the bottom plate is arranged vertically displaceable relative to the side walls.

Gemäß der. Erfindung weist der Lagerbereich des Behälters eine Bodenplatte auf, die gegenüber den Seitenwänden vertikal beweglich angeordnet ist. Die Bodenhöhe des Lagerbereichs kann somit verändert und der Trockeneis-Füllmenge angepasst werden. Vermindert sich die Füllmenge durch Entnahme, wird die Bodenplatte entsprechend angehoben, und zwar bevorzugt derart, dass ein Benutzer das von ihm benötigte Trockeneis stets von der ungefähr gleichen Entnahmehöhe abschöpfen kann. Dadurch wird die Zugänglichkeit der in Behälter befindlichen Trockeneisteilchen erleichtert. Selbst bei fast vollständig geleertem Behälter ist es somit für einen Benutzer nicht mehr erforderlich, sich über oder in den Behälter hinein zu beugen, wodurch das gesundheitliche Risiko erheblich verringert wird.According to the. Invention, the storage area of the container on a bottom plate which is arranged vertically movable relative to the side walls. The floor level of the storage area can thus be changed and the dry ice capacity adjusted. Reduces the amount of filling by removal, the bottom plate is raised accordingly, preferably in such a way that a user can always skim the dry ice he needs from the approximately same removal height. This facilitates the accessibility of the dry ice particles in containers. Even with almost completely emptied container, it is thus no longer necessary for a user to bend over or into the container, whereby the health risk is considerably reduced.

Zur Bewegung der Bodenplatte kommt vorzugsweise ein hydraulischer oder pneumatischer Antrieb zum Einsatz; die Bewegung der Bodenplatte wird also mittels eines strömenden, gasförmigen oder flüssigen Fluides gesteuert. Dabei wird das Fluid manuell oder motorgetrieben in einen Druckbehälter gepresst, der sich bevorzugt unterhalb der Bodenplatte im Behälter befindet und von dem aus der Druck zur Hebung der Bodenplatte ausgeübt wird. Durch Abströmen des Fluids aus dem Druckbehälter wird umgekehrt die Bodenplatte wieder abgesenkt. Auf diese Weise kann die Höhe der Bodenplatte einfach den jeweiligen Erfordernissen angepasst werden. Als pneumatischer Antrieb kommt beispielsweise ein unterhalb der Bodenplatte angeordneter, aufblasbarer Ballon zum Einsatz, der mittels einer geeigneten Gaspumpe mit einem Gas, etwa Luft oder Stockstoff, befüllt wird und die Bodenplatte entgegen der Gewichtskraft der Trockeneisteilchen nach oben drückt. Beim hydraulischen Antrieb kann es sich beispielsweise um eine hydraulische Höhenverstellung handeln, wie sie etwa von Operationsliegen oder Friseurstühlen bekannt ist.To move the bottom plate is preferably a hydraulic or pneumatic drive used; the movement of the bottom plate is thus controlled by means of a flowing, gaseous or liquid fluid. The fluid is pressed manually or motor driven in a pressure vessel, which is preferably below the bottom plate in the container and from which the pressure is exerted to lift the bottom plate. By flowing the fluid out of the pressure vessel, conversely, the bottom plate is lowered again. In this way, the height of the bottom plate can be easily adapted to the respective requirements. As a pneumatic drive, for example, an arranged below the bottom plate, inflatable balloon is used, which is filled by means of a suitable gas pump with a gas, such as air or nitrogen, and pushes the bottom plate against the weight of the Trockeneisteilchen up. The hydraulic drive may be, for example, a hydraulic height adjustment, as is known for example from operating chairs or barber chairs.

Alternativ oder ergänzend zum vorgenannten pneumatischen oder hydraulischen Antrieb kommt zur Bewegung der Bodenplatte ein - vorzugsweise elektrisch angetriebener - Motor zum Einsatz. Der Motor sorgt dabei entweder direkt, beispielsweise über eine Vortriebsspindel oder über geeignete Zugsysteme, für die Bewegung der Bodenplatte, oder indirekt durch eine Förderung der Fluidströme innerhalb der vorgenannten pneumatischen oder hydraulischen Systeme. Idealerweise wird dabei die Höhe der Bodenplatte, beispielsweise über einen geeigneten Sensor, der die Füllhöhe oder die Masse des noch vorhandenen Trockeneises misst, der Füllmenge automatisch angepasst.Alternatively or in addition to the aforementioned pneumatic or hydraulic drive comes to move the bottom plate a - preferably electrically driven - motor used. The engine provides either direct, for example, via a propelling spindle or via suitable traction systems, for the movement of the bottom plate, or indirectly by conveying the fluid streams within the aforementioned pneumatic or hydraulic systems. Ideally, the height of the bottom plate, for example, via a suitable sensor that measures the filling level or the mass of the remaining dry ice, the capacity automatically adjusted.

Eine ebenfalls alternative und gleichfalls zweckmäßige Möglichkeit, die Anpassung des Niveaus der Bodenplatte an die jeweilige Füllmenge der Bodenplatte zu gewährleisten, besteht in der Ausnutzung von Federkräften, die der Gewichtskraft der im Behälter aufgenommenen Trockeneisteilchen entgegenwirken. Die hierzu benötigten Federn können beispielsweise unterhalb der Bodenplatte angeordnet und der Gewichtskraft des Trockeneises durch Druck entgegenwirken. Besonders vorteilhaft wirken die Federkräfte als Zugkräfte und werden von Federelementen vermittelt, die zwischen der Bodenplatte und den Seitenwänden angeordnet sind. Beispielsweise ist dazu die Bodenplatte an mehreren Federn aufgehängt, die an den Seitenwänden selbst oder an einem Rahmen im Bereich der Oberkante der Seitenwände befestigt sind.A likewise alternative and likewise expedient possibility of ensuring the adaptation of the level of the base plate to the respective filling quantity of the base plate consists in the utilization of spring forces which counteract the weight force of the dry ice particles received in the container. The springs required for this purpose can be arranged, for example, below the bottom plate and counteract the weight of the dry ice by pressure. Particularly advantageous, the spring forces act as tensile forces and are mediated by spring elements which are arranged between the bottom plate and the side walls. For example, for this purpose, the bottom plate is suspended on a plurality of springs, which are fastened to the side walls themselves or to a frame in the region of the upper edge of the side walls.

Anhand der Zeichnungen sollen Ausführungsbeispiele der Erfindung näher erläutert werden. In schematischen Ansichten zeigen in Schnittansichten:

  • Fig. 1: Eine erste Ausführungsform und
  • Fig. 2: Eine zweite Ausführungsform eines erfindungsgemäßen Behälters.
Reference to the drawings, embodiments of the invention will be explained in more detail. In schematic views show in sectional views:
  • Fig. 1 : A first embodiment and
  • Fig. 2 : A second embodiment of a container according to the invention.

Der in Fig. 1 gezeigte Behälter 1 zum Aufbewahren von Trockeneis umfasst einen Ladebereich 2, der seitlich von vier Seitenwänden begrenzt wird, von denen im Bild nur die Seitenwände 3, 4 gezeigt sind. Der Ladebereich hat beispielsweise eine maximale Kapazität von 50 kg bis 500 kg Trockeneisteilchen in Form von Schnee, Pellets, Nuggets, Scherben oder Scheiben. Die Seitenwände 3,4 bestehen aus Kunststoff oder Metall und sind mit einer thermischen Isolation versehen. Beispielsweise weisen die Seitenwände 3,4 eine Außenhaut aus Polyethylen auf und sind im Innern in an sich bekannter Weise mit einer Schaumisolation ausgerüstet. An der Seitenwand 3 ist ein gleichfalls thermisch isolierter Deckel 5 angelenkt, der im geschlossenen Zustand den Ladebereich 2 des Behälters 1 vollständig überdeckt und damit das Eindringen von feuchter Umgebungsluft in den Behälter 1 zuverlässig verhindert. Durch geeignete und hier nicht gezeigte Schließsysteme kann der Deckel 5 mit der Seitenwand 4 verbunden werden. Es ist im Rahmen der Erfindung auch vorstellbar, dass der Behälter 1 hermetisch mit dem Deckel 5 verschlossen wird; in diesem Fall ist jedoch ein Ventil vorzusehen, das das Entweichen von im Ladebereich sublimierendem Kohlendioxid ermöglicht.The in Fig. 1 1 shown for storing dry ice comprises a loading area 2, which is bounded laterally by four side walls, of which only the side walls 3, 4 are shown in the image. The loading area has, for example, a maximum capacity of 50 kg to 500 kg of dry ice particles in the form of snow, pellets, nuggets, broken glass or slices. The side walls 3,4 are made of plastic or metal and are provided with a thermal insulation. For example, the side walls 3,4 an outer skin made of polyethylene and are equipped in the interior in a conventional manner with a foam insulation. On the side wall 3, a likewise thermally insulated lid 5 is articulated, which in closed state completely covers the loading area 2 of the container 1 and thus reliably prevents the ingress of moist ambient air into the container 1. By suitable and not shown here locking systems, the lid 5 can be connected to the side wall 4. It is also conceivable within the scope of the invention that the container 1 is hermetically sealed with the lid 5; in this case, however, a valve must be provided which allows the escape of sublimating carbon dioxide in the loading area.

Auf seiner geodätisch gesehen unteren Fläche wird der Ladebereich 2 von einer Bodenplatte 7 begrenzt. Die Bodenplatte 7 besteht im Ausführungsbeispiel aus drei übereinander angeordneten Segmenten: Ausgehend vom Ladebereich 2 befindet sich zuoberst eine bevorzugt aus Metall, beispielsweise Edelstahl, bestehende Deckplatte 8, deren Fläche im Wesentlichen der Fläche der Bodenplatte 7 entspricht. Unterhalb der Deckplatte 8 ist eine thermische Isolierschicht 9 aus beispielsweise geschäumtem Kunststoff angeordnet, die auf einem Stützabschnitt 10 aufliegt. Der Stützabschnitt 10, der zur mechanischen Stabilisierung der Bodenplatte 7 dient, muss nicht notwendigerweise aus einer die gesamte Fläche ausfüllende Platte bestehen, sondern es kann sich dabei ebenso gut um ein Stützskelett, beispielsweise eine Rohrkonstruktion, handeln. In einer sehr einfachen Ausführungsform der Erfindung kann im Übrigen der Bodenbereich aus einer einzigen Platte aus Kunststoff oder Metall bestehen. Eine solche Ausführungsform ist freilich weniger bevorzugt, da bei ihr die Sublimationsrate des im Ladebereich 2 gelagerten Trockeneises höher ist als bei einer Ausführungsform mit thermisch gut isolierter Bodenplatte 7. Um zu verhindern, dass Trockeneisteilchen durch einen sich zwischen den Seitenwänden und der Bodenplatte 7 öffnenden Spalt hindurch fallen können, ist im Ausführungsbeispiel am Rand der Deckplatte 8 ein rundumlaufendes Dichtelement 11 angeordnet, beispielsweise eine Bürste oder ein Kunststoffelement, das auch bei der Temperatur des Trockeneises von - 78,4 °C noch eine gewisse Flexibilität aufweist.On its geodetically seen lower surface of the loading area 2 is bounded by a bottom plate 7. The bottom plate 7 consists in the embodiment of three superimposed segments: Starting from the loading area 2 is located at the top of a preferably made of metal, such as stainless steel, existing cover plate 8, whose surface corresponds substantially to the surface of the bottom plate 7. Below the cover plate 8, a thermal insulating layer 9 is arranged, for example, foamed plastic, which rests on a support portion 10. The support portion 10, which serves for the mechanical stabilization of the bottom plate 7, does not necessarily consist of a plate filling the entire surface, but it can just as well be a supporting skeleton, for example a tubular construction. Incidentally, in a very simple embodiment of the invention, the bottom portion may consist of a single plate of plastic or metal. However, such an embodiment is less preferred because it has a higher sublimation rate of dry ice stored in the loading area 2 than in a thermally insulated bottom plate 7 embodiment can fall through, in the exemplary embodiment at the edge of the cover plate 8, a circumferential sealing element 11 is arranged, for example, a brush or a plastic element, which still has a certain flexibility at the temperature of the dry ice of - 78.4 ° C.

Der Stützabschnitt 10 der Bodenplatte 7 ist auf einer hydraulischen Hebeeinrichtung 12 aufmontiert, mittels der die gesamte Bodenplatte 7 gegenüber den Seitenwänden 3,4 gehoben oder gesenkt werden kann. Die hydraulische Hebeeinrichtung 12 wird dabei im Ausführungsbeispiel mit Hilfe eines Motors 13 betätigt. Anstelle der im Ausführungsbeispiel gezeigten hydraulischen Hebeeinrichtung 12 kann ebenso gut auch eine pneumatische Hebeeinrichtung zum Einsatz kommen, beispielsweise ein aufblasbarer Ballon, der unterhalb der Bodenplatte 7 angeordnet ist. Ebenso kann auch eine manuelle, hydraulische oder pneumatische Hebeeinrichtung zum Einsatz kommen.The support portion 10 of the bottom plate 7 is mounted on a hydraulic lifting device 12, by means of which the entire bottom plate 7 can be raised or lowered relative to the side walls 3,4. The hydraulic lifting device 12 is actuated in the embodiment by means of a motor 13. Instead of the Embodiment shown hydraulic lifting device 12 may also be used as well as a pneumatic lifting device, for example, an inflatable balloon, which is arranged below the bottom plate 7. Likewise, a manual, hydraulic or pneumatic lifting device can be used.

Die hydraulische Hebeeinrichtung 12, der Motor 13 sowie die Seitenwände 3,4 des Behätters1 sind auf einem Tragegestell 15 montiert, das beispielsweise ebenfalls eine Rohrkonstruktion ist. Zur Erleichterung des Transports sind im Ausführungsbeispiel nach Fig. 1 am Tragegestell 15 unterseitig Rollen 16 vorgesehen.The hydraulic lifting device 12, the motor 13 and the side walls 3,4 of the Behätters1 are mounted on a support frame 15, which is also a pipe construction, for example. To facilitate transport are in the embodiment according to Fig. 1 rollers 16 are provided on the support frame 15 on the underside.

Beim Einsatz des Behälters 1 wird der Ladebereich 2 mit Trockeneisteilchen bis zu einer Füllhöhe 17 befüllt. Durch Entnahme von Trockeneisteilchen und durch Sublimation reduziert sich die Füllhöhe 17 im Laufe der Zeit. Um einem Bediener den Zugriff auf die Trockeneisteilchen so einfach wie möglich zu machen und insbesondere zu verhindern, dass er sich dabei über den Behälter 1 oder in diesen hinein beugen muss, wird die Bodenplatte 7 durch Betätigen der hydraulischen Hebeeinrichtung 12 so weit gehoben, dass die Füllhöhe 17 gegenüber der Oberkante der Seitenwände 3, 4 wieder ungefähr auf dem vorherigen Stand vorliegt. Bei der Neubefüllung des Behälters 1 wird dagegen die Bodenplatte 7 so weit abgesenkt, dass sich bei der entsprechenden Befüllmenge die Füllhöhe 17 Trockeneisteilchen auf einem für den Benutzer bequem erreichbaren Niveau befindet. Die Anpassung der Füllhöhe erfolgt dabei entweder durch manuelle Ingangsetzung der Hebeeinrichtung 12 durch einen Benutzer, oder automatisiert, in dem die Menge des im Ladebereich 2 vorhandenen Trockeneises durch einen Sensor, der beispielsweise das Gewicht der Trockeneisladung oder die aktuelle Füllhöhe detektiert, erfasst und anschließend über eine hier nicht gezeigte Regelungsautomatik die Höhe der Bodenplatte 7 automatisch angepasst wird.When using the container 1, the loading area 2 is filled with dry ice particles up to a filling level 17. By removing dry ice particles and by sublimation, the filling level 17 is reduced over time. In order to make the access to the dry ice particles as easy as possible for an operator and in particular to prevent him from having to bend over the container 1 or into it, the base plate 7 is lifted by actuating the hydraulic lifting device 12 so far that the Fill level 17 relative to the upper edge of the side walls 3, 4 is again approximately at the previous level. When refilling the container 1, however, the bottom plate 7 is lowered so far that the filling level 17 Trockeneisteilchen is at a level that is easily accessible to the user at the appropriate filling. The adjustment of the filling level is carried out either by manual startup of the lifting device 12 by a user, or automated, in which the amount of existing in the loading area 2 dry ice by a sensor that detects, for example, the weight of the dry ice or the current filling height, and then on an automatic control, not shown here, the height of the bottom plate 7 is automatically adjusted.

Der in Fig. 2 gezeigte Behälter 20 weist gleichfalls wie der Behälter 1 aus Fig. 1 einen Ladebereich 22 auf, der von vier thermisch isolierten Seitenwänden, von denen hier nur die Seitenwände 23, 24 gezeigt sind, einem an einer Seitenwand 23 angelenkten Deckel 25 und einer Bodenplatte 27 umschlossen wird. Ähnlich wie die Bodenplatte 7 aus Fig. 1 ist auch die Bodenplatte 27 aus drei übereinander angeordneten Segmenten aufgebaut, nämlich aus einer Deckplatte 28, einer sich an die Deckplatte 28 anschließenden Isolierschicht 29 und einem Stützabschnitt 30. Weiterhin ist die Deckplatte 28 mit einem Dichtelement 31 ausgerüstet, dass einen sich zwischen dem Umfang der Deckplatte 28 und den Seitenwänden öffnenden Spalt derart abdichtet, so dass weder Trockeneisteilchen durch den Spalt herausfallen können, noch feuchte Außenluft in den Ladebereich 22 eindringen kann. Der Aufbau und die Funktion der Elemente 28, 29, 30, 31 entsprechen dem Aufbau und der Funktion der Elemente 8, 9, 10, 11 der in Fig. 1 gezeigten Ausführungsform. Die Seitenwände 23,24 des Behälters 20 sind auf einem Tragegestell 35 montiert, das beispielsweise ebenfalls eine Rohrkonstruktion ist. Zur Erleichterung des Transports sind bei diesem Ausführungsbeispiel am Tragegestell 35 unterseitig Stützfüße 36 angeordnet, die ein Untergreifen des Behälters 20 durch einen Gabelstapler ermöglichen; es können jedoch selbstverständlich in beiden Ausführungsformen Rollen oder Stützfüße zum Einsatz kommen.The in Fig. 2 shown container 20 also has the same as the container 1 Fig. 1 a loading area 22, which is surrounded by four thermally insulated side walls, of which only the side walls 23, 24 are shown here, a lid 25 hinged to a side wall 23 and a bottom plate 27. Similar to the bottom plate 7 off Fig. 1 is also the bottom plate 27 of three superimposed arranged segments, namely a cover plate 28, an adjoining the cover plate 28 insulating layer 29 and a support portion 30. Further, the cover plate 28 is equipped with a sealing element 31 that a between the periphery of the cover plate 28 and the side walls opening gap such seals so that neither Trockeneisteilchen can fall out through the gap, or moist outside air can enter the loading area 22. The structure and function of the elements 28, 29, 30, 31 correspond to the structure and function of the elements 8, 9, 10, 11 of FIG Fig. 1 shown embodiment. The side walls 23,24 of the container 20 are mounted on a support frame 35, which is also a pipe construction, for example. To facilitate transport, support feet 36 are arranged in this embodiment on the support frame 35 on the underside, which allow underreaching of the container 20 by a forklift; however, it is of course possible to use rollers or support feet in both embodiments.

Die Bodenplatte 27 ist vertikal beweglich gegenüber den Seitenwänden 23,24 im Behälter 20 aufgenommen. Hierzu ist auf den dem Tragegestell 35 entgegen gesetzten Oberkanten der Seitenwände 23,24 ein vorzugsweise metallischer Rahmen 32 montiert. Am Rahmen 32 sind an geeigneten Befestigungselementen, beispielsweise an am Rahmen 32 angeschweißten oder angeschraubten Ösen, mehrere Federn 33, 34 angeordnet, die an ihrem dem Rahmen 32 entgegen gesetzten Ende mit dem Stützabschnitt 30 der Bodenplatte 27 verbunden sind. Zu diesem Zweck weist auch der Stützabschnitt 30 geeignete Befestigungselemente, beispielsweise an am Stützabschnitt angeschweißte oder angeschraubte Ösen, auf. Um die Last der Bodenplatte 27 und die im Ladebereich 22 vorhandene Ladung zu tragen, werden je nach Geometrie des Behälters und dem Ladegewicht beispielsweise vier bis zwölf ringsherum voneinander beabstandet am Rahmen 32 angeordnete Federn 33, 34 aufgewendet. Die Federn 33, 34 wirken der Gewichtskraft einer Füllung von Trockeneisteilchen im Ladebereich 22 entgegen, sodass sich die Federlängen bei Befüllung des Ladebereiches 22 vergrößern und bei Reduzieren der Füllmasse im Ladebereich 22 verringern. Auf diese Weise bleibt die Füllhöhe 37 der Befüllung, gemessen an den Seitenwänden 23, 24, auch bei unterschiedlichen Füllmengen stets ungefähr auf gleich bleibender Höhe.The bottom plate 27 is vertically movably received against the side walls 23, 24 in the container 20. For this purpose, a preferably metallic frame 32 is mounted on the support frame 35 opposite upper edges of the side walls 23,24. On the frame 32, a plurality of springs 33, 34 are arranged on suitable fastening elements, for example on the frame 32 welded or screwed eyelets, which are connected at its the frame 32 opposite end to the support portion 30 of the bottom plate 27. For this purpose, the support portion 30 has suitable fastening elements, for example on eyelets welded or screwed to the support section. In order to carry the load of the bottom plate 27 and the charge present in the loading area 22, depending on the geometry of the container and the load weight, for example, four to twelve spaced around the frame 32 arranged springs 33, 34 expended. The springs 33, 34 counteract the weight of a filling of dry ice particles in the loading area 22, so that the spring lengths increase upon filling of the loading area 22 and decrease when the filling area in the loading area 22 is reduced. In this way, the filling level 37 of the filling, measured at the side walls 23, 24, even at different levels always remains approximately at the same level.
