Abstract

A hinged package (1) for food products, especially hamburgers, has two shaped halves (2, 3) which are recessed, joined together via a hinge (7), complement one another and can be folded into a closed position in which they enclose a receiving space for the food product. The closed position can be secured by closure parts (8, 9) on the shaped halves (2, 3). The shaped halves (2, 3) consist of baked dough. The hinge (7) also consists of an edible substance which, however, remains soft and flexible.

Description

Die Erfindung bezieht sich auf eine Klappverpackung für Lebensmittel, insbesondere Hamburger, mit zwei über ein Scharnier aneinanderhängenden, vertieften Formhälften, die einander ergänzen und in eine Schließlage klappbar sind, in der sie einen Aufnahmeraum für das Lebensmittel umhüllen, wobei die Schließlage durch Verschlußteile an den Formhälften sicherbar ist. Eine solche Klappverpackung ist aus der US-A-4 787 552 bekannt. Solche Klappverpackungen dienen insbesondere in Schnellbedienungsrestaurants zum Verpacken von Lebensmitteln, insbesondere Hamburger, Bouletten, Schnitzel sowie entsprechenden Beilagen.The invention relates to a folding packaging for food, in particular hamburgers, with two hinged, recessed mold halves that complement one another and can be folded into a closed position in which they envelop a receiving space for the food, the closed position being closed by closure parts on the Mold halves can be secured. Such a folding packaging is known from US-A-4 787 552. Such folding packaging is used in particular in fast service restaurants for packaging food, in particular hamburgers, boulettes, schnitzel and corresponding side dishes.

Bisher bekannte Klappverpackungen bestehen aus geschäumten Kunststoff. Die beiden Formhälften werden aneinanderhängend hergestellt und sind über ein Scharnier miteinander verbunden, wobei die Wandstärke im Bereich des Scharniers zweckmäßig geringer ausfällt als im übrigen Bereich der Formhälften In aufnahmebereitem Zustand befinden sich die beiden Formhälften in einer gestreckten, offenen Lage, so daß der durch die beiden Vertiefungen gebildete Innenraum noch nicht zusammenhängend zur Verfügung gestellt wird. Das zu verpackende Lebensmittel wird in die eine Formhälfte eingebracht und die andere Formhälfte wird über das Scharnier um etwa 180° in Richtung auf die erste Formhälfte geklappt, wobei die Schließlage erreicht wird. Dabei wird das Lebensmittel von der Klappverpackung gänzlich umhüllt und die Formhälften gelangen mit ihren Rändern aufeinanderliegend in Kontakt. Die Schließlage ist zweckmäßig durch Verschlußteile an den Formhälften sicherbar. Zu diesem Zweck kann an der einen Formhälfte eine Öffnung und anderen Formhälfte eine Lasche angeformt sein, wobei die Lasche in der Schließlage in die Öffnung eingesteckt wird, so daß die Schließlage gesichert ist und trotz des Rückfederungsvermögens im Bereich des Scharniers die Schließlage beibehalten bleibt, bis die Verschlußteile wiederum voneinander gelöst werden. Solche Klappverpackungen werden insbesondere auch für den Außerhausverkauf von frisch zubereiteten, eßbaren Lebensmitteln der angesprochenen Art eingesetzt. Da sie aus geschäumtem Kunststoff bestehen, erfüllen sie auch eine gewisse Warmhaltefunktion und lassen sich leicht transportieren. Es entsteht jedoch das Entsorgungsproblem, denn der zur Herstellung der Klappverpackung eingesetzte Kunststoff zersetzt sich schlecht und belastet insoweit die Umwelt durch Vergrößerung des Müllbergs. Auch sind manche Kunststoffe nicht frei von Schadstoffabgaben, die zumindest teilweise auch in das verpackte Lebensmittel gelangen können und dann zwangsweise mitgegessen werden. Durch entsprechende Beschichtungen auf den Formhälften der Klappverpackung kann dem entgegengewirkt werden, wobei sich aber wiederum die Herstellung verteuert. Wenn solche Klappverpackungen in Parks sowie zu anderen öffentlichen Plätzen mitgenommen werden und nach dem Verzehr des Lebensmittels weggeworfen werden, entsteht nicht nur ein unschöner Anblick, sondern letztlich auch ein beachtlicher Aufwand für eine Einsammlung, Entfernung und Entsorgung.Known folding packaging consists of foamed plastic. The two mold halves are made to hang together and are connected to each other via a hinge, the wall thickness in the area of the hinge advantageously being less than in the remaining area of the mold halves.In the ready-to-shoot state, the two mold halves are in an extended, open position, so that the through interior formed in both recesses is not yet provided contiguously. The food to be packaged is introduced into one half of the mold and the other half of the mold is folded over the hinge by approximately 180 ° in the direction of the first half of the mold, the closed position being reached. The food is completely enveloped by the folding packaging and the halves of the mold come into contact with one another with their edges. The closed position can expediently be secured by closure parts on the mold halves. For this purpose, an opening can be formed on one half of the mold and a flap can be formed on the other half of the mold, the flap being inserted into the opening in the closed position, so that the closed position is secured and the closed position is retained despite the resilience in the area of the hinge until the Closure parts are in turn detached from one another. Such folding packaging is used in particular for the out-of-home sale of freshly prepared, edible foods of the type mentioned. Since they are made of foamed plastic, they also fulfill a certain warming function and are easy to transport. However, the disposal problem arises because the plastic used to produce the folding packaging decomposes poorly and in this respect pollutes the environment by enlarging the rubbish pile. Also, some plastics are not free of pollutant emissions, which can at least partially get into the packaged food and are then forcibly eaten. This can be counteracted by appropriate coatings on the mold halves of the folding packaging, but this in turn increases the cost of manufacture. If such collapsible packaging is taken away from parks and other public places and thrown away after eating the food, not only does it look ugly, but ultimately it also involves considerable effort for collection, removal and disposal.

Aus der DE-OS 36 39 185 ist eine Verpackung aus organischen Stoffen in beliebiger Formgebung für die Einbringung von Lebensmitteln bekannt, die als Futtermittel oder auch als Lebensmittel benutzt werden kann. Die Verpackung besteht aus zwei aufeinandersteckbaren Teilen aus einen dünnflüssigen Getreidemehlteig, also beispielsweise als Waffel. Der einander zugekehrte Randbereich der Teile ist gestuft ausgebildet, so daß hier eine Steckverbindung gebildet werden kann, die noch einen Mehl-, Ei- oder Zuckerkleber verfestigt werden kann. Nachteilig ist an dieser bekannten Verpackung ist es, daß sie nicht wie die eingeführte Klappverpackung aus Kunststoff gehandhabt werden. Das Aufeinanderstecken der beiden zueinandergehörigen Teile muß sehr genau erfolgen, weil sonst die dünnen Ränder beim Zusammenfügen der beiden Hälften der Verpackung zerstört bzw. zumindest beschädigt werden. Da die Ränder gestuft ausgebildet sind, muß eine vergleichsweise große Wandstärke der Verpackung gewählt werden, um überhaupt im Randbereich die erforderliche Festigkeit zu erzielen. Es ist auch möglich, eine Oblatenteil zusätzlich mit einzubacken. Ein Porenverschluß der Teile der Verpackung kann durch Gelatine erreicht werden.From DE-OS 36 39 185 a packaging made of organic substances in any shape for the introduction of food is known, which can be used as feed or as food. The packaging consists of two parts that can be plugged together and are made of a thin, liquid flour batter, for example as a waffle. The mutually facing edge region of the parts is stepped, so that here a plug connection can be formed, which can also be solidified with a flour, egg or sugar glue. The disadvantage of this known packaging is that it is not handled like the plastic folding packaging introduced. The stacking of the two related parts must be done very precisely, because otherwise the thin edges when joining the two Halves of the packaging are destroyed or at least damaged. Since the edges are stepped, a comparatively large wall thickness of the packaging must be selected in order to achieve the required strength in the edge area at all. It is also possible to additionally bake a part of the wafer. A pore closure of the parts of the packaging can be achieved by gelatin.

Aus der FR-PS 26 28 398 ist eine Steckverpackung für Hamburger und ähnliche Gerichte bekannt, bei der ebenfalls zwei unterschiedliche, jedoch einander zugeordnete Teile aufeinandergesteckt werden. Die Verpackung besteht aus ungesäuertem Brot und kann entsprechend gewürzt sein. Die beiden Teile der Verpackung können einander übergreifend aufeinandergesteckt sein oder über eine Art Schnappverschluß miteinander verbunden sein. Die Verpackung ist dazu bestimmt, gemeinsam mit dem Inhalt verzehrt zu werden, also ohne ein vorheriges Öffnen der Verpackung.From FR-PS 26 28 398 a push-in packaging for hamburgers and similar dishes is known, in which two different, but mutually associated parts are also plugged together. The packaging consists of unleavened bread and can be seasoned accordingly. The two parts of the packaging can be placed one on top of the other or connected to one another via a kind of snap lock. The packaging is intended to be consumed together with the contents, i.e. without opening the packaging beforehand.

Der Erfindung liegt die Aufgabe zugrunde, hier wirksame Abhilfe zu schaffen und eine Klappverpackung der eingangs beschriebenen Art bereitzustellen, die leicht abbaubar ist und bei der das Problem der Entsorgung weitgehend entschärft ist.The invention has for its object to provide an effective remedy here and to provide a folding packaging of the type described above, which is easily degradable and in which the problem of disposal is largely alleviated.

Erfindungsgemäß wird dies dadurch erreicht, daß die Formhälften aus gebackenem Teig bestehen, und daß das Scharnier aus einem anderen eßbaren Stoff besteht, der jedoch weich und flexibel bleibt. Das Scharnier kann somit insbesondere aus Kaugummi, Gelatine oder Weingummi bestehen. Mit der Erfindung wird eine eßbare Verpackung geschaffen, die in aller Regel zusätzlich zu dem in der Verpackung transportierten Lebensmittel verzehrt wird, so daß die Klappverpackung auf öffentlichen Plätzen weder eingesammelt werden muß noch einer Müllentsorgung mit ggf. anschließender Deponie unterliegt. Die Klappverpackungen, die nicht verzehrt werden, unterliegen einem schnellen Abbau durch Verrottung, wenn sie nicht von Vögeln und anderen Tieren gefressen werden. Die Formhälften selbst bestehen aus gebackenem Teig, insbesondere Waffelteig, der auch in verschiedenen Geschmacksrichtungen, abgestimmt auf das jeweils zu verpackende Lebensmittel, eingesetzt werden kann. Bei einer Klappverpackung für Hamburger wird zweckmäßig auf den Einsatz eines süßen Waffelteigs, wie er für die Herstellung von Eistüten bekannt ist, verzichtet und stattdessen ein neutraler, salziger oder mit einem sonstigen Gewürz gewürzter Teig verwendet. Durch das Backen des Teigs entstehen die Formhälften mit einer hinreichenden Wandstärke, die auch den Belastungen während des Transports der mit dem Lebensmittel gefüllten Klappverpackung standhält. Die beiden Formhälften sind weitgehend starr und vergleichsweise wenig flexibel, während umgekehrt das die beiden Formhälften verbindende Scharnier aus einem solchen eßbaren Stoff bestehen muß, der weich und flexibel bleibt, damit das Zuklappen der Klappverpackung in die Schließlage möglich wird, ohne daß sich das Scharnier von den Formhälften löst. In aller Regel ist die Beanspruchung des Scharniers jedoch nicht sehr hoch. Die Scharnierwirkung wird in aller Regel nur zweimal, nämlich beim Zuklappen und beim Aufklappen vor dem unmittelbaren Verzehr in Anspruch genommen. Bei einem Teilverzehr der verpackten Ware können einige weitere wenige Umklappvorgänge stattfinden, so daß jedenfalls das Scharnier frei von einer Dauerbelastung ist. Insoweit kann das Scharnier aus verschiedenen eßbaren Stoffen bestehen. Es kann hier durchaus auch ein z. B. süßer Stoff eingesetzt werden, dem eine gewisse Dessert-Funktion zukommen kann. Es versteht sich, daß die Anbringung des Scharniers an den beiden Formhälften so geschehen muß, daß einerseits die Scharnierfunktion erfüllt und andererseits das Lösen des Scharniers vor Gebrauch von den Formhälften verhindert wird.According to the invention this is achieved in that the mold halves consist of baked dough and that the hinge is made of another edible material, which remains soft and flexible. The hinge can thus consist in particular of chewing gum, gelatin or wine gum. With the invention, an edible packaging is created, which is usually consumed in addition to the food transported in the packaging, so that the folding packaging in public places neither must still be collected is subject to waste disposal with subsequent landfill. The folding packaging, which is not consumed, is subject to rapid degradation by rotting if it is not eaten by birds and other animals. The mold halves themselves consist of baked dough, especially waffle dough, which can also be used in different flavors, tailored to the food to be packaged. In the case of a folding packaging for hamburgers, it is advisable not to use a sweet waffle dough, as is known for the production of ice cream cones, and instead to use a neutral, salty or seasoned dough. Baking the dough creates the mold halves with a sufficient wall thickness, which also withstands the stresses during transportation of the folding packaging filled with the food. The two mold halves are largely rigid and comparatively little flexible, while, conversely, the hinge connecting the two mold halves must consist of such an edible material that remains soft and flexible, so that the folding packaging can be closed in the closed position without the hinge becoming detached the mold halves. As a rule, however, the stress on the hinge is not very high. The hinge effect is usually only used twice, namely when closing and when opening before being consumed. If the packaged goods are partially consumed, a few more few folding operations can take place, so that the hinge is in any case free from permanent stress. In this respect, the hinge can consist of various edible substances. It can also be a z. B. sweet material can be used, which can have a certain dessert function. It goes without saying that the hinge must be attached to the two mold halves in such a way that on the one hand it fulfills the hinge function and on the other hand it prevents the hinge from being released from the mold halves before use.

Es ist möglich, daß die beiden Formhälften bei getrennter Herstellung nur über das Scharnier miteinander verbunden sind. In diesem Fall ist es möglich, die beiden Formhälften, die auch in identischer Ausbildung vorliegen können, getrennt voneinander zu backen und erst durch das Anbringen des Scharniers miteinander zu verbinden. Die Anbringung des Scharniers geschieht in aller Regel erst nach dem Backvorgang.It is possible for the two mold halves to be connected to one another only via the hinge in the case of separate production. In this case, it is possible to bake the two mold halves, which can also be of identical design, separately from one another and to connect them only by attaching the hinge. The hinge is usually only attached after the baking process.

Es ist aber auch möglich, daß die beiden Formhälften zusammenhängend gebacken werden und im Bereich des Scharniers eine Perforation oder eine sonstige Sollbruchstelle geschaffen wird. Die Sollbruchstelle wird dann ganz oder teilweise mit einem oder mehreren Streifen aus dem eßbaren Stoff, der das Scharnier bildet, überbrückt. Die Sollbruchstelle kann auch durch eine Schwachstelle, also einen Bereich entsprechend verminderter Wandstärke, an der Übergangsstelle zwischen den beiden Formhälften, entstehen. Auch durch nachträgliches Ausstanzen oder die Anbringung von Anschnitten kann diese Sollbruchstelle gebildet bzw. vorbereitet werden.However, it is also possible for the two mold halves to be baked together and for a perforation or other predetermined breaking point to be created in the area of the hinge. The predetermined breaking point is then bridged in whole or in part with one or more strips of the edible material that forms the hinge. The predetermined breaking point can also arise from a weak point, that is to say an area of correspondingly reduced wall thickness, at the transition point between the two mold halves. This predetermined breaking point can also be formed or prepared by subsequent punching out or the application of gates.

Die in Figur 1 dargestellte Klappverpackung 1 weist zwei Formhälften 2, 3 auf, die aneinanderhängend aus Teig gebacken sind, und zwar ähnlich, wie dies beim Backen von Waffeln, Eistüten u. dgl. bekannt ist. Die beiden Formhälften 2, 3 weisen jeweils eine Vertiefung 4 auf, besitzen ähnliche, einander ergänzende Form und können aus der dargestellten flachliegenden Stellung in eine Schließlage umgeklappt werden, in welcher die beiden Vertiefungen 4 einen Aufnahmeraum für das zu umhüllende Lebensmittel abgeben. Im Übergangsbereich 5 ist die Wandstärke geringer ausgebildet. Es kann hier auch eine Sollbruchstelle 6 in Form eines sehr dünnen Stegs vorgesehen sein, der durchbricht, sobald ein gewisser Verschwenkwinkel der beiden Formhälften 2 und 3 in die Schließlage hinein überschritten wird. Auch eine Perforation oder eine Stanzung in diesem Bereich ist möglich. Die beiden Formhälften 2 und 3 werden in diesem Übergangsbereich von einem Scharnier 7 überbrückt, welches aus einem durchgehenden Materialstreifen aus einem eßbaren Stoff, der weich und flexibel bleibt, besteht. Hierfür kommt insbesondere Kaugummi, Weingummi, eine Bonbonmasse o. dgl. in Frage. Wichtig ist es, einen solchen eßbaren Stoff zur Ausbildung des Scharniers 7 zu wählen, der einerseits die erforderliche Flexibilität behält und andererseits auch die erforderliche Verbindung mit dem Teig der beiden Formhälften 2 und 3 eingeht.The folding packaging 1 shown in Figure 1 has two mold halves 2, 3, which are baked together from dough, similar to how this is done when baking waffles, ice cream cones and the like. Like. Is known. The two mold halves 2, 3 each have a recess 4, have a similar, complementary shape and can be folded from the flat position shown into a closed position in which the two recesses 4 release a receiving space for the food to be wrapped. In the transition area 5, the wall thickness is made smaller. A predetermined breaking point 6 in the form of a very thin web can also be provided here, which breaks through as soon as a certain pivoting angle of the two mold halves 2 and 3 is exceeded into the closed position. Perforation or punching in this area is also possible. The two mold halves 2 and 3 are bridged in this transition area by a hinge 7, which consists of a continuous strip of material made of an edible material that remains soft and flexible. Chewing gum, wine gum, a candy mass or the like are particularly suitable for this. It is important to choose such an edible material for forming the hinge 7, which on the one hand retains the required flexibility and on the other hand also forms the required connection with the dough of the two mold halves 2 and 3.

Die beiden Formhälften 2 und 3 weisen Verschlußteile 8, 9 auf, wobei an der Formhälfte 2 eine Lasche 8 und am Formteil 3 eine Öffnung 9 oder eine Durchbrechung vorgesehen ist, die in ihrer Größe und Lage aufeinander abgestimmt sind. In der Schließlage wird die Lasche 8 in die Öffnung 9 einsteckt und die Schließlage ist damit gesichert, so daß die Klappverpackung 1 geschlossen ist und so das eingeschlossene Lebensmittels transportiert werden kann.The two mold halves 2 and 3 have closure parts 8, 9, a tab 8 being provided on the mold half 2 and an opening 9 or an opening being provided on the molded part 3, the size and position of which are matched to one another. In the closed position, the tab 8 is inserted into the opening 9 and the closed position is thus secured, so that the hinged packaging 1 is closed and the enclosed food can be transported.

Das Ausführungsbeispiel der Figuren 3 und 4 ist an sich ähnlich aufgebaut wie die Klappverpackung 1 nach dem Ausführungsbeispiel der Figuren 1 und 2. Es besteht hier nur der Unterschied, daß die Formhälften 2 und 3 als separate Teile gebacken werden und ein Übergangsbereich fehlt. Stattdessen sind an die Formhälften 2 und 3 Übergangsstreifen 10 und 11 angeformt. Das Scharnier 7 wird hier von mehreren Streifen 12 gemeinsam gebildet, die die beiden Übergangsstreifen 10 und 11 miteinander verbinden und sich auch noch bis zu einer gewissen Tiefe in die Wandung der Formhälften 2 und 3 hinein erstrecken können.The embodiment of Figures 3 and 4 is constructed in a similar way to the folding packaging 1 according to the embodiment of Figures 1 and 2. There is only the difference here that the mold halves 2 and 3 are baked as separate parts and a transition area is missing. Instead, transition strips 10 and 11 are formed on the mold halves 2 and 3. The hinge 7 is formed here by several strips 12 which connect the two transition strips 10 and 11 to one another and can also extend to a certain depth into the wall of the mold halves 2 and 3.
