Description

Der im Schutzanspruch 1 angegebenen •Erfmdting'fiegt da% Problem zugrunde, ein Verschließgerät zu schaffen welches, die schon vorhandenen und branchenüblichen Materialien und Schließtechnologien so modifiziert, daß die entstehende Lösung in einer völlig neuen Zusammensetzung, auch bei Materialien deren Einsatz bis jetzt nicht ermöglicht werden konnte, verwendet werden kann.The invention specified in claim 1 is based on the problem of creating a closing device which modifies the existing and industry-standard materials and closing technologies in such a way that the resulting solution can be used in a completely new composition, even with materials whose use has not been possible up to now.

Dieses Problem wird mit den im Schutzanspruch 1 aufgeführten Merkmalen gelöstThis problem is solved with the features listed in claim 1

Mit der Erfindung wird erreicht, daß die Menüschalen nach außen und unter den Menüschalenkammern luftdicht verschloßen (versiegelt) werden, so daß die gewünschte Schwappsicherheit bei jeglicher Handhabung und Transport gesichert ist. Die Entfernung der Heißsiegelfolie ist bei Einhaltung der Verschließtechnologie rückstandfrei und problemlos. Der Einsatz der Verschließvorrichtung schließt jedoch die übliche Behandlung der befüllten Menüschalen wie das Regenerieren in Konvektomaten und Mikrowellengeräten nicht aus.
Weitere Vorteile der Erfindung sind im Schutzanspruch 2 und 3 angegeben.The invention ensures that the meal trays are hermetically sealed to the outside and underneath the meal tray chambers, so that the desired level of sloshing safety is ensured during any handling and transport. The removal of the heat-sealing film is residue-free and problem-free if the sealing technology is adhered to. However, the use of the sealing device does not exclude the usual treatment of the filled meal trays, such as regeneration in convection ovens and microwave ovens.
Further advantages of the invention are set out in claims 2 and 3.

Die Verschließvorrichtung wird mit einer befüllten und vorgeheizten Menüschale{5) so bestückt, daß die Menüschale{5) unterhalb der Heizplatte(l) so zentriert untergebracht wird, daß die mit der Hand zugeführte Heißsiegelfolie(4) am effektivsten ausgenützt werden kann. Die, mit der Ausgleichschicht(2) bestückte Heizplatte(l) wird auf die Heißsiegelfolie{4) und zugleich auf die Menüschale(5) mit so einer Tauchtiefe gepresst, daß dabei eine ausreichend große Kontaktfläche zum Versiegeln entsteht und die Schließkantenabweichungen von der Ebene ausreichend ausgeglichen werden können. Nach dem Versiegeln wird der Pressvorgang abgeschlossen und die Vorrichtung kann wieder neubestückt werden. Die so versiegelten Menüschalen(5) können gleich verpackt werden.The sealing device is equipped with a filled and preheated menu tray {5) in such a way that the menu tray {5) is placed centrally under the heating plate (l) so that the manually fed heat-sealing film (4) can be used most effectively. The heating plate (l) equipped with the leveling layer (2) is pressed onto the heat-sealing film {4) and at the same time onto the menu tray (5) with such a depth that a sufficiently large contact surface for sealing is created and the closing edge deviations from the plane can be adequately compensated. After sealing, the pressing process is completed and the device can be re-equipped. The menu trays (5) sealed in this way can be packaged immediately.

BeschreibungDescription

Vorrichtung zum Versiegeln von Behältern, vorzugsweise Menüschalen aus starren WerkstofDevice for sealing containers, preferably menu trays made of rigid material

Für einen Menübringdienst stehen unterschiedlichste Transport- und Verpackungsysteme zur Verfugung, welche vorwiegend Einwegsysteme sind.A wide variety of transport and packaging systems are available for a meal delivery service, which are mainly disposable systems.

Einige alternative Mehrwegsysteme aus unterschiedlichen Werkstoffen wie Edelstahl, Kunststoff und Porzellan wurden zwar entwickelt, sind aber wegen ihrer unzureichenden Schließtechnologien, immer noch mit Mangeln behaftet. ■ .Some alternative reusable systems made of different materials such as stainless steel, plastic and porcelain have been developed, but they still have shortcomings due to their inadequate locking technologies. ■ .

Die zum Schließen verwendeten, hauptsächlich aus Kunststoff hergestellten Deckel bieten weder nach außen noch unterhalb der Menüschalenkammern die notwendige Schwappsicherheit. Der Grund dafür sind die bei der Herstellung der Porzellanmenüschalen entehenden fertigungsbedingten Abweichungen der Schließkanten von der Ebene. Die Abweichungen können in Extremfällen bis zu mehreren Millimetern betragen und es ist kaum möglich dies mit einem aus starrem Kunststoff hergestellten Deckel so auszugleichen, daß die gewünschte Schwappsicherheit in jeder. Transportlage gegeben werden kann. Darüber hinaus lassen sich diese Menüschalen in den meisten Fällen, bei neuen Deckeln ganz besonderes, nur sehr schwer öffnen.The lids used for closing, which are mainly made of plastic, do not provide the necessary anti-sloshing protection either on the outside or underneath the meal tray chambers. The reason for this is the manufacturing-related deviations of the closing edges from the plane that occur during the manufacture of the porcelain meal trays. In extreme cases, the deviations can be up to several millimeters and it is hardly possible to compensate for this with a lid made of rigid plastic in such a way that the desired anti-sloshing protection can be provided in every transport position. In addition, these meal trays are very difficult to open in most cases, especially with new lids.

Claims (3)

SchutzansprücheProtection claims 1. Beheizbare Vorrichtung zum Versiegeln von Behältern, vorzugsweise Menüschalen aus starren Werkstoffen wie Keramik, Glas oder Edelstahl mit jeweils einer ganz aus Kunststoff oder aus einer mit Kunststoff beschichteten · Metallfolie hergestellten Heißsiegelfolie, welche eine Ausgleich schicht aufweist, die dazu dient die fertigungsbedingten Abweichungen der Schließkanten von der Ebene der Behälter (Menüschalen) auszugleichen, dadurch gekennzeichnet, daß die Ausgleichschicht{2) eine hohe Flexibilität und Wärmebeständigkeit besitzt.1. Heatable device for sealing containers, preferably menu trays made of rigid materials such as ceramic, glass or stainless steel, each with a heat-sealing film made entirely of plastic or of a plastic-coated metal foil, which has a compensating layer which serves to compensate for the production-related deviations of the closing edges from the plane of the containers (menu trays), characterized in that the compensating layer{2) has a high degree of flexibility and heat resistance. 2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Ausgleichschicht(2) zwischen, der Heizplatte(l) und der Heißsiegelfolie(4j untergebracht ist und eine Mindeststärke von 6-8mm hat, um das gemeisame Eindrücken der Schließkanten der Transportschale(5) und der Heißsiegelfolie(4) in die Ausgleichschicht(2) so tief zu ermöglichen, daß die dadurch entstehende vergrößerte Kontaktfläche durch die Wärmeeinwirkung der Vorrichtung zu einem stabilen Versiegeln führt.2. Device according to claim 1, characterized in that the compensating layer (2) is accommodated between the heating plate (1) and the heat-sealing film (4) and has a minimum thickness of 6-8 mm in order to enable the closing edges of the transport tray (5) and the heat-sealing film (4) to be pressed together into the compensating layer (2) so deeply that the resulting enlarged contact surface leads to a stable sealing due to the heat effect of the device. 3. Vorrichtung nach Anspruch 1 und 2 dadurch gekennzeichnet, daß zwischen der Ausgleich schicht(2) und der Heißsiegelfolie(4) noch eine Trennfolie(3) untergebracht ist, um das Verkleben der Heißsiegelfolie(4) an der Ausgleichschicht(2) zu verhindern.3. Device according to claim 1 and 2, characterized in that a separating film (3) is accommodated between the compensating layer (2) and the heat-sealing film (4) in order to prevent the heat-sealing film (4) from sticking to the compensating layer (2).
