Description

Die Erfindung betrifft Behälter, insbesondere zur Aufbewahrung von Lebensmitteln, Speisen oder Getränken, wie sie insbesondere im gewerblichen Bereich Verwendung finden, also z. B. in Grossküchen, Krankenhäusern, Kantinen oder ähnlichem. Bevor­ zugt kommen hier genormte Behälter zum Einsatz ("Gastronormbehälter"), deren Längen-, Breiten- und Tiefenmasse standardisiert sind und die auch vorgegebenen Qualitätsmerkmalen hinsichtlich Oberfläche und Material entsprechen. Gegebenen­ falls weisen sie zur leichteren Handhabung zusätzliche Ausstattungen auf, wie z. B. Griffe im Randbereich.The invention relates to containers, in particular for storing food, Food or beverages, such as those used in particular in the commercial sector find, e.g. B. in canteen kitchens, hospitals, canteens or the like. Before standardized containers are used here ("Gastronorm containers"), their Length, width and depth dimensions are standardized and the specified ones Corresponding quality features with regard to surface and material. Given if they have additional equipment for easier handling, such as. B. Handles in the edge area.

In den Grossküchen, in denen Gastronorm-Behälter Anwendung finden, wird in der Regel das Essen gekocht und dann im heissen Zustand in diese Behälter gefüllt, so dass sie dann in Essensausgabe-Einheiten als Vorrats- oder Ausgabebehälter benutzt werden können. Da die Speisen mit der Zeit abkühlen, werden diese Behälter in Vor­ richtungen gebracht, in denen sie zusammen mit dem eingebrachten Essen warm ge­ halten werden können oder auch in Vorrichtungen, in denen das Essen aufgeheizt wird.In the canteen kitchens where Gastronorm containers are used, the Usually the food is cooked and then filled into these containers when hot, so that it is then used in food serving units as a storage or serving container can be. As the food cools over time, these containers become pre brought directions in which they warm together with the food brought in can be kept or in devices in which the food is heated becomes.

Derartige Vorrichtungen sind in der Regel stationär, oftmals für eine grössere Anzahl solcher genormter Behälter ausgelegt und daher nur bedingt wirtschaftlich.Such devices are usually stationary, often for a larger number such standardized container designed and therefore only partially economical.

Der stationäre Charakter dieser Vorrichtungen hat auch den Nachteil, dass auch bei isolierten Behältern die mittlere Aufbewahrungszeit, in der das Essen noch zum Ver­ zehr ausreichend warm ist, und damit auch der "Versorgungsbereich" begrenzt ist.The stationary nature of these devices also has the disadvantage that also insulated containers the mean storage time in which the food is still for ver zehr is sufficiently warm, and thus the "supply area" is limited.

Es ist daher Aufgabe der Erfindung, eine flexiblere Lösung zu schaffen, die auch in kleinerem Maßstab wirtschaftlich einsetzbar ist und eine Erwärmung bzw. ein Warm­ halten der Speisen oder Getränke zuverlässig bewerkstelligt.It is therefore an object of the invention to provide a more flexible solution that also in on a smaller scale can be used economically and a warming or a warm keep the food or drinks reliably accomplished.

Erfindungsgemäss wird diese Aufgabe durch einen Behälter gemäss dem kennzeich­ nenden Teil des Patentanspruchs 1 gelöst. According to the invention, this object is achieved by a container according to the label ning part of claim 1 solved.  

Der Grundgedanke der Erfindung ist also darin zu sehen, die Heiz- oder Wärmfunktion unmittelbar dem Behälter zuzuordnen, so dass eine räumlich und auch zeitlich flexible Beheizung/Erwärmung der Speisen erfolgen kann, wobei auch eine individuelle Ab­ stimmung betreffend Heizdauer und Heiztemperatur auf das jeweilige Essen in dem jeweiligen Normbehälter möglich wird.The basic idea of the invention is therefore to be seen in the heating or heating function assign directly to the container, so that it is spatially and temporally flexible Heating / heating of the dishes can take place, whereby also an individual Ab mood regarding heating duration and heating temperature for the respective food in the respective standard container is possible.

Der Grundaufbau Innenbehälter-Heizelement-Aussenschale kann daher in diesem Sinn als Sandwich-Aufbau bezeichnet werden, wobei die einzelnen Schichten speziell auf ihre jeweilige Funktion hinsichtlich Materialstärke und Materialwahl optimiert wer­ den können; so kann beispielsweise der Innenbehälter aus Edelstahl sein, um vorge­ gebene Hygiene- und Reinigungsanforderungen erfüllen zu können, wogegen die Au­ ssenschale aus einem thermisch isolierenden Kunststoff gebildet sein kann, um sicher zu stellen, dass die vom Heizelement abgegebene Wärmemenge zum weit überwie­ genden Teil an den Innenbehälter und damit die dort aufbewahrten Speisen abgege­ ben wird.The basic structure of the inner container heating element outer shell can therefore be used in this Meaning as a sandwich structure, with the individual layers being special who is optimized for their respective function with regard to material thickness and material selection that can; for example, the inner container can be made of stainless steel, in order existing hygiene and cleaning requirements, whereas the Au can be formed from a thermally insulating plastic to be safe to make sure that the amount of heat given off by the heating element far exceeded to the inner container and thus the food stored there will.

Bevorzugte Ausbildungen der erfindungsgemässen Lösung sind den Unteransprüchen zu entnehmen, ein Ausführungsbeispiel wird nun anhand von Zeichnungen näher er­ läutert. Es zeigen:Preferred embodiments of the solution according to the invention are the subclaims It can be seen that an exemplary embodiment will now be used with reference to drawings purifies. Show it:

Fig. 1 eine Explosionsdarstellung des Behälters und Fig. 1 is an exploded view of the container and

Fig. 2 einen Schnitt durch den zusammengesetzten Behälter entsprechend Fig. 1. Fig. 2 shows a section through the assembled container according to FIG. 1.

Der Behälter besteht aus einem Innenbehälter 10 mit umlaufendem Rand 10A, mit dem er vorzugsweise in entsprechend angepasste Regale oder Profile eingehängt oder eingeschoben werden kann.The container consists of an inner container 10 with a peripheral edge 10 A, with which it can preferably be suspended or inserted into suitably adapted shelves or profiles.

Ein Heizelement 20 in Form einer elektrischen Heizmatte überdeckt beim dargestell­ ten Ausführungsbeispiel vollflächig die Aussenwandung des Innenbehälters 10, wobei die beiden Anschlussdrähte 20A, 20B des Heizelements 20 zu zwei Kontaktelementen 11A, 11B auf der Unterseite des umlaufenden Randes 10A geführt sind. Eine Aussen­ schale 30, beispielsweise aus wärmeisolierendem Polycarbonat mit ausreichender Wanddicke umschliesst die Heizmatte von aussen. Nach dem Zusammenbau dieser Bauteile werden diese dann in der Regel auf Dauer zusammengehalten, beispielswei­ se durch Verspritzen, wenn Innenbehälter 10 und Aussenschale 30 aus Kunststoff bestehen, oder durch andere geeignete Verbindungstechniken bei Behältern aus ver­ schiedenen Materialien.A heating element 20 in the form of an electric heating mat completely covers the outer wall of the inner container 10 in the embodiment shown, the two connecting wires 20 A, 20 B of the heating element 20 being guided to two contact elements 11 A, 11 B on the underside of the peripheral edge 10 A . An outer shell 30 , for example made of heat-insulating polycarbonate with a sufficient wall thickness, encloses the heating mat from the outside. After assembly of these components, these are then usually held together permanently, for example by spraying, if the inner container 10 and outer shell 30 are made of plastic, or by other suitable connection techniques for containers made of different materials.

Bei dem in Fig. 2 dargestellten Ausführungsbeispiel sind die beiden Anschlusskon­ takte 11A und 11B an gegenüberliegenden Seiten des umlaufenden Randes 10A an­ geordnet.In the embodiment shown in Fig. 2, the two Anschlusskon contacts 11 A and 11 B are arranged on opposite sides of the peripheral edge 10 A.

Es ist auch möglich, anstelle einer elektrischen Heizmatte als flächigem Heizelement 20 eine vorheizbare Wärmespeichermatte, beispielsweise in Form eines latenten Wärmespeichers aus einem technischen Wachs auf Paraffinbasis einzusetzen; diese Lösung wird insbesondere dann von Interesse sein, wenn mit dem erfindungsgemä­ ssen Behälter Transportstrecken zu überwinden sind, bei denen eine kontinuierliche Stromversorgung für eine Heizmatte nicht zur Verfügung steht.It is also possible to use a preheatable heat storage mat instead of an electric heating mat as a flat heating element 20 , for example in the form of a latent heat storage made from a technical wax based on paraffin; this solution will be of particular interest if transport routes are to be overcome with the container according to the invention, in which a continuous power supply for a heating mat is not available.

Es ist natürlich auch grundsätzlich möglich, diese beiden Massnahmen zu kombinie­ ren und eine elektrische Heizmatte in einem derartigen Wärmespeicher einzubetten, so dass Heiz- und Wärmespeicherfunktion im gewünschten Mass je nach Einsatz­ zweck des Behälters aufeinander abgestimmt werden können.It is of course also possible in principle to combine these two measures Ren and embed an electric heating mat in such a heat storage, so that heating and heat storage function to the desired extent depending on the application Purpose of the container can be coordinated.

Durch die Integration dieser Heiz- und Wärmefunktion (die natürlich auch als Kühlung verwendet werden kann, beispielsweise durch eine entsprechend vorkühlbare Spei­ chermatte) wird der Behälter zu einem "aktiven Behälter", dessen Funktion über die reine Aufbewahrung und den Transport von Speisen hinausgeht.By integrating this heating and heating function (which of course also serves as cooling can be used, for example by means of a correspondingly pre-coolable memory chermatte) the container becomes an "active container", whose function is via the pure storage and transportation of food goes beyond.
