Description

Lebensmittelverpackung mit Kleπ-melementen Food packaging with adhesive elements
Die Erfindung betrifft eine Lebensmittelverpackung, insbeson- dere einen Eierkarton, mit einem Unterteil, das mindestens eine Reihe von Formvertiefungen zur Aufnahme von vereinzelten Lebensmittelstücken, insbesondere Eiern, aufweist, und einem Deckelteil, das klappbar an dem Unterteil angeordnet ist, wobei das Unterteil und das Deckelteil mit komplementären Klem- merhebungen und Klemmöffnungen versehen sind.The invention relates to a food packaging, in particular an egg carton, with a lower part which has at least one row of recesses for receiving individual pieces of food, in particular eggs, and a lid part which is arranged foldably on the lower part, the lower part and the Cover part are provided with complementary clamp elevations and clamp openings.
Eierkartons mit komplementären Klemmerhebungen und Klemmöffnungen an dem Unterteil und an dem Oberteil sind an sich bekannt (zum Beispiel FR-A-2 441 549). Bei der bekannten Ver- packung sind jedoch die Klemmerhebungen und die Klemmöffnungen so angeordnet, daß beim Übereinanderstapeln von Eierkartons die Klemmerhebungen eines Eierkartons in die Klemmöffnungen des darüber bzw. darunter befindlichen Eierkartons eingreifen. Diese Anordnung der Klemmerhebungen und Klemmöff- nungen erlaubt zwar einen sicheren Verbund unmittelbar übereinander gestapelter Eierkartons, jedoch erweist sich dies als nachteilig, wenn Eierkartons einzeln entnommen werden sollen, beispielsweise zum Verkauf. Über das Verklemmen unmittelbar übereinander gestapelter Eierkartons hinaus bietet die Anordnung der Klemmerhebungen und -Öffnungen bei den bekannten Eierkartons keine zusätzliche Funktionalität. Der Erfindung liegt die Aufgabe zugrunde, eine Lebens ittelverpackung der eingangs genannten Art zu schaffen, bei der die Funktionalität der Klemmelemente verbessert ist.Egg boxes with complementary clamping elevations and clamping openings on the lower part and on the upper part are known per se (for example FR-A-2 441 549). In the known packaging, however, the clamping elevations and the clamping openings are arranged such that when egg cartons are stacked one on top of the other, the clamping elevations of an egg carton engage in the clamping openings of the egg carton above or below. Although this arrangement of the clamping elevations and clamping openings permits a secure bond between egg boxes stacked directly one above the other, this proves to be disadvantageous if egg boxes are to be removed individually, for example for sale. In addition to the jamming of egg boxes stacked directly one above the other, the arrangement of the clamp elevations and openings in the known egg boxes does not offer any additional functionality. The invention has for its object to provide a food packaging of the type mentioned, in which the functionality of the clamping elements is improved.
Die erfindungsgemäße Lösung liegt in einer Lebensmittelverpackung mit den Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.The solution according to the invention lies in a food packaging with the features of claim 1. Advantageous further developments result from the subclaims.
Erfindungsgemäß ist bei einer Lebensmittelverpackung, insbe- sondere einem Eierkarton, mit einem Unterteil, das mindestens eine Reihe von Formvertiefungen zur Aufnahme von vereinzelten Lebensmittelstücken, insbesondere Eiern, aufweist, und einem Deckelteil, das klappbar an dem Unterteil angeordnet ist, wobei das Unterteil und das Deckelteil mit komplementären Klem- merhebungen und Klemmöffnungen versehen sind, vorgesehen, daß die Klemmöffnungen an einem der beiden, dem Deckelteil oder dem Unterteil, und die Klemmerhebungen an dem anderen der beiden, dem Unterteil oder dem Deckelteil, angeordnet sind, wobei die Klemmöffnungen seitlich versetzt in Bezug auf die Klemmerhebungen angeordnet sind.According to the invention, in the case of a food packaging, in particular an egg carton, with a lower part which has at least one row of recesses for receiving individual pieces of food, in particular eggs, and a lid part which is foldably arranged on the lower part, the lower part and the Cover part are provided with complementary clamping elevations and clamping openings, it is provided that the clamping openings are arranged on one of the two, the cover part or the lower part, and the clamping elevations on the other of the two, the lower part or the cover part, the clamping openings being offset laterally are arranged in relation to the clamp elevations.
Durch die erfindungsgemäße Ausgestaltung wird erreicht, daß die Klemmerhebungen und Klemmöffnungen unmittelbar übereinander gestapelter Lebensmittelverpackungen nicht fluchten mit- einander angeordnet sind und deshalb nicht ineinander eingreifen können. Ein Verklemmen unmittelbar übereinander gestapelter Eierverpackungen wird auf diese Weise vermieden. Dennoch, und darin liegt der Pfiff der Erfindung, können übereinander gestapelte Lebensmittelverpackungen miteinander klemmend verbunden werden, und zwar, wenn sie versetzt zueinander angeordnet sind. Dies bietet eine überraschende zusätzliche Funktionalität. Herkömmlicherweise haben Lebensmittel- Verpackungen, nachdem ihr Inhalt aufgebraucht ist, keine weitere Funktion; sie werden weggeworfen, nachdem ihr Inhalt entnommen ist. Die Erfindung stellt eine zweite Verwendungsmöglichkeit für die Lebensmittelverpackungen, insbesondere für Eierkartons bereit. Durch die komplementären Klemmerhebungen und -Öffnungen können die nach Gebrauch leeren Lebensmittelverpackungen nämlich weiterhin verwendet werden, und zwar als Klemmbausteine. Somit können die erfindungsgemäßen Lebensmittelverpackungen, nachdem sie ihrer Verpackungsfunk- tion genügt haben, noch als Spielzeug dienen. Da Lebensmittelverpackungen im Vergleich zu klassischen Klemmbausteinen verhältnismäßig große Abmessungen aufweisen, eigenen sie sich insbesondere zur Bildung vergleichsweise großer Strukturen, wie zum Beispiel zum Aufbau von Spielburgen für Kinder, die mit herkömmlichen Klemmbausteinen nicht oder nur mit unverhältnismäßig hohem Aufwand hergestellt werden können. Dank ihrer Größe ermöglichen sie so einen raschen Aufbau auch großer Strukturen. Darüber hinaus haben die erfindungsgemäßen Lebensmittelverpackungen den Vorteil, daß sie als Klemmbau- steine nahezu kostenlos zur Verfügung stehen.The configuration according to the invention ensures that the clamping elevations and clamping openings of food packages stacked directly one above the other are not aligned with one another and therefore cannot interlock. This prevents jamming of egg packages stacked directly one above the other. Nevertheless, and this is the whistle of the invention, food packages stacked on top of one another can be connected to one another by clamping, if they are arranged offset to one another. This offers surprising additional functionality. Traditionally, food Packaging, after its content has been used up, no further function; they are thrown away after their content is removed. The invention provides a second possible use for food packaging, in particular for egg cartons. Because of the complementary clamp elevations and openings, the food packaging that is empty after use can still be used, namely as clamp modules. Thus, the food packaging according to the invention can still serve as a toy after it has served its packaging function. Since food packaging has relatively large dimensions in comparison to classic clamping blocks, it is particularly suitable for the formation of comparatively large structures, such as the construction of play castles for children, which cannot be produced with conventional clamping blocks or only with disproportionately high expenditure. Thanks to their size, they enable rapid construction even of large structures. In addition, the food packaging according to the invention has the advantage that it is available as clamping blocks almost free of charge.
Die erfindungsgemäße Anordnung der Klemmerhebungen und Klemmöffnungen hat ferner den Vorteil, daß die Stapelbarkeit der Lebensmittelverpackungen im geöffneten Zustand unbeeinträch- tigt bleibt. Die Verpackungen können weiterhin im geöffneten Zustand gestapelt und gegebenenfalls auch leicht entstapelt werden. Damit dies Entstapeln (Entnesten) leicht gelingt, sind die Klemmerhebungen und/oder Klemmöffnungen vorzugsweise nicht höher bzw. tiefer als eine maximale Nestungshöhe. Der Betrag der maximalen Nestungshöhe ist von den konkreten Parametern der jeweiligen Lebensmittelverpackung abhängig, insbesondere der gewünschten Entnestungsfähigkeit und dem erfor- derlichen Platzbedarf. Abhängig von der Materialstärke und dem Reibungskoeffizienten des Materials beträgt die Nestungshöhe in der Regel zwischen 4 und 15 mm und liegt vorzugsweise zwischen 7 und 9 mm. Dank der damit erreichten Stapelbarkeit verringern sich sowohl für den Hersteller wie auch für dasThe arrangement of the clamp elevations and clamp openings according to the invention also has the advantage that the stackability of the food packaging remains unimpaired in the open state. The packaging can still be stacked in the open state and, if necessary, also easily unstacked. So that this unstacking (denesting) can be easily accomplished, the clamping elevations and / or clamping openings are preferably not higher or lower than a maximum nesting height. The amount of the maximum nesting height depends on the specific parameters of the respective food packaging, in particular the desired denesting capacity and the required space requirements. Depending on the material thickness and the coefficient of friction of the material, the nesting height is generally between 4 and 15 mm and is preferably between 7 and 9 mm. Thanks to the stackability thus achieved, both for the manufacturer and for the
Verpackungsunternehmen die Lagerkosten und das Verpacken kann rationeller erfolgen.Packing companies can reduce storage costs and packaging more efficiently.
Zweckmäßigerweise sind die Klemmöffnungen so angeordnet, daß sie im geschlossenen Zustand des Deckelteils etwa mittig über zwei in einer Reihe benachbarten Klemmerhebungen angeordnet sind. Mit einem solchen Versatz können mehrere erfindungsgemäße Lebensmittelverpackungen besonders gut im Verbund zueinander angeordnet werden. Dadurch können stabile, über längere Strecken laufende Wandabschnitte aufgebaut werden oder es können sogar Eckverbindung geschaffen werden.The clamping openings are expediently arranged in such a way that, when the cover part is in the closed state, they are arranged approximately centrally over two clamping elevations adjacent in a row. With such an offset, several food packaging according to the invention can be arranged particularly well in a composite with one another. As a result, stable wall sections running over longer distances can be built up or even corner connections can be created.
Zur besseren Verbindung mehrerer Lebensmittelverpackungen im Verbund ist zweckmäßigerweise die Oberkante des Deckelteils so ausgestaltet, daß ihr Abstand zu der randnächsten Klemmöffnung höchstens so groß ist, wie der freie Abstand zwischen benachbarten Klemmerhebungen. Unter freier Abstand wird die lichte Weite zwischen zwei benachbarten Klemmerhebungen verstanden. Mit dieser Gestaltung wird erreicht, daß die Klem- merhebungen einer aufgesetzten Lebensmittelverpackung entweder in die Klemmöffnungen auf dem Deckelteil der unteren Lebensmittelverpackung eingreifen oder sich jenseits der Oberkante des Deckelteils befinden. Dadurch wird vermieden, daß Klemmerhebungen direkt auf der Oberseite des Deckelteils auf- liegen, wodurch die obere Lebensmittelverpackung schief positioniert würde und ein sicherer und korrekter Sitz der Lebensmittelverpackung verhindert würde. Zweckmäßigerweise weisen die Klemmerhebungen und die Klemmöffnungen eine Konizität von 2° bis 15°, vorzugsweise von 7° bis 9° auf. Mit einer solchen Konizität läßt sich einerseits eine gute Sicherheit der Klemmverbindung erzielen, andererseits ermöglicht sie aber noch ein hinreichend leichtes Trennen der Lebensmittelverpackungen, ohne das dazu übermäßiger Kraftaufwand erforderlich ist. Dies gilt insbesondere für das Entnesten von im geöffneten Zustand gestapelten Lebensmittel- Verpackungen.For a better connection of several food packaging in the composite, the upper edge of the lid part is expediently designed such that its distance from the terminal opening closest to the edge is at most as large as the free distance between adjacent terminal elevations. Free space is understood to mean the clear width between two adjacent clamp elevations. With this design it is achieved that the clamping elevations of an attached food packaging either engage in the clamping openings on the lid part of the lower food packaging or are located beyond the upper edge of the lid part. This prevents jamming bumps from lying directly on the top of the lid part, which would position the upper food packaging at an angle and prevent the food packaging from sitting securely and correctly. The clamping elevations and the clamping openings expediently have a taper of 2 ° to 15 °, preferably 7 ° to 9 °. With such a taper, a good security of the clamp connection can be achieved, on the one hand, but on the other hand, it enables the food packaging to be separated with sufficient ease, without the need for excessive force. This applies in particular to the denesting of food packaging stacked in the open state.
Vorzugsweise sind die Klemmerhebungen an ihrem unteren Rand mit einer Ringstruktur als Ausbuchtung versehen. Besonders bewährt hat sich eine Ringstruktur, die torusartig ausgebil- det ist, so daß sich eine torusartige Ausnehmung bildet. Aufgrund ihrer Form bildet sie eine gesteigerte Elastizität in diesem Bereich, durch die das verpackte Lebensmittel besonders gut gegen Beschädigungen durch Stoß, beispielsweise durch hartes Aufsetzen, geschützt wird. Somit verbessern der- artige Ausbuchtungen nicht nur die Schutzfunktion, sondern zusätzlich verbessern sie auch den optischen Gesamteindruck der Lebensmittelverpackung.The clamping elevations are preferably provided with a ring structure as a bulge on their lower edge. A ring structure which has a toroidal design has proven particularly useful, so that a toroidal recess is formed. Due to its shape, it forms an increased elasticity in this area, by means of which the packaged food is particularly well protected against damage due to impact, for example due to hard placement. Such bulges not only improve the protective function, they also improve the overall visual impression of the food packaging.
Vorzugsweise sind mindestens sechs Klemmerhebungen vorgese- hen, angeordnet in Doppelreihe. Es versteht sich, daß dann auch eine entsprechende Anzahl, z. B. vier, Klemmöffnungen vorzusehen sind. Mit dieser Anzahl kann eine stabile Klemmverbindung von mehreren Lebensmittelverpackungen im Verbund erreicht werden. Selbstverständlich können auch acht oder mehr Klemmerhebungen vorgesehen sein. Gemäß einer besonders bevorzugten Ausführungsform, die gegebenenfalls auch unabhängigen Schutz verdient, weist das Dek- kelteil einen nach oben offenen Trog und ein Abdeckmittel auf, der den Trog nach oben hin abdeckt. Unter nach oben of- fen ist hierbei zu verstehen, daß der Trog im geschlossenenAt least six clamp elevations are preferably provided, arranged in a double row. It is understood that a corresponding number, for. B. four, clamping openings are to be provided. With this number, a stable clamping connection of several food packaging can be achieved in the network. Of course, eight or more clamp elevations can also be provided. According to a particularly preferred embodiment, which possibly also deserves independent protection, the cover part has a trough which is open at the top and a covering means which covers the trough at the top. Open to the top here means that the trough is closed
Zustand des Deckelteils von außen zugänglich ist. Dadurch wir erreicht, daß zum einen mit dem Trog ein zusätzliches Aussteifungselement zur Verfügung steht, zum anderen wird erreicht, daß der Trog und das Abdeckmittel einen Raum schaf- fen, in den Gegenstände eingelegt werden können. Das Abdeckmittel verhindert, daß der eingelegte Gegenstand ungewollt aus dem Trog herausfällt. Dazu ist das Abdeckmittel so ausgebildet, daß es in Verbindung mit dem Trog einen abgeschlossenen Aufnahmeraum bildet. Vorzugsweise weisen die Flanken und der Boden des Trogs keine Durchbrechungen oder nur Durchbrechungen mit einer lichten Weite auf, die klein genug ist, um einen ungewollten Durchgang der einzulegenden Gegenstände zu verhindern. Die einzulegenden Gegenstände sind vorzugsweise bereits von dem Lieferanten der Lebensmittelverpackung einge- legt worden, können aber gegebenenfalls auch erst beim Verpacken der Lebensmittel oder später von einem Händler hineingelegt werden. Bei dem Gegenstand kann es sich beispielsweise um Zettel mit Rezeptinformationen oder um Kleinutensilien, insbesondere um Kinderspielzeug, einen Eierlöffel und/oder um eine Portionstüte mit Gewürzen handeln. Der Kunde erhält dann mit der Lebensmittelverpackung nicht nur die darin enthaltenen Lebensmittel, sondern als Mehrwert auch den in den Trog eingelegten Gegenstand. Das Abdeckmittel hat außer seiner sichernden Funktion noch eine weitere, wichtige Wirkung. Der Benutzer muß das Abdeckmittel erst von dem Trog entfernen, um an den darin befindlichen Gegenstand zu gelangen. Durch dieses Auspacken entsteht bei dem Nutzer eine freudige Erwar- tungshaltung auf das, was unter dem Abdeckmittel zum Vorschein kommen wird, ähnlich dem Überraschungseffekt beim Auspacken von Geschenken. Da der Benutzer bereits bei dem Kauf der Lebensmittel weiß, daß er später diesen angenehmen Über- raschungseffekt erleben wird, stellt sich ihm die Lebensmittelverpackung schon bei der Kaufentscheidung in einem günstigen Licht dar. Damit kommt die erfindungsgemäße Lebensmittelverpackung der wichtigen Funktion einer Verpackung, nämlich außer dem Schütze darin enthaltenen Ware auch den Kunden zu einem Kauf zu animieren, in besonders hohem Maße nach.Condition of the cover part is accessible from the outside. This means that on the one hand an additional stiffening element is available with the trough, on the other hand it is achieved that the trough and the covering means create a space in which objects can be inserted. The covering means prevents the inserted object from accidentally falling out of the trough. For this purpose, the cover means is designed so that it forms a closed receiving space in connection with the trough. The flanks and the bottom of the trough preferably have no openings or only openings with a clear width which is small enough to prevent an undesired passage of the objects to be inserted. The objects to be inserted have preferably already been inserted by the supplier of the food packaging, but may also only be inserted when the food is packed or later by a dealer. The item can be, for example, notes with recipe information or small items, in particular children's toys, an egg spoon and / or a portion bag with spices. The customer then not only receives the food contained in the food packaging, but also the object placed in the trough as added value. In addition to its securing function, the covering means has another important effect. The user must first remove the covering means from the trough in order to access the object contained therein. This unpacking creates a joyful expectation for the user. attitude towards what will appear under the cover, similar to the surprise effect when unwrapping gifts. Since the user already knows when buying the food that he will later experience this pleasant surprise effect, the food packaging is presented to him in a favorable light when the purchase decision is made. The food packaging according to the invention therefore fulfills the important function of packaging, namely to particularly encourage the goods contained in the shooter to encourage the customer to make a purchase.
Darüber hinaus wirkt der Trog auch noch aussteifend für das Deckelteil. Er bildet mit seinen Flanken eine zusätzliche Verrippung für das Deckelteil, welches so an Steifigkeit ge- winnt. Damit verbessert sich auch die Schutzfunktion der erfindungsgemäßen Lebensmittelverpackung. Es ergibt sich insgesamt also ein überraschender kombinatorischer Effekt, daß nämlich einerseits die Lebensmittelverpackung versteift wird und damit das aufgenommene Lebensmittel besser geschützt ist, und andererseits die Präsentation dadurch verbessert wird, daß ein Aufnahmeraum für kleine Gegenstände geschaffen ist.In addition, the trough also has a stiffening effect for the cover part. With its flanks, it forms additional ribbing for the cover part, which gains rigidity. This also improves the protective function of the food packaging according to the invention. Overall, there is a surprising combinatorial effect, namely that on the one hand the food packaging is stiffened and thus the ingested food is better protected, and on the other hand the presentation is improved in that a receiving space for small objects is created.
Vorzugsweise ist das Abdeckmittel ein Aufkleber. Damit kann auf besonderes rationelle und kostengünstige Weise der Trog abgedeckt werden. Außerdem stellt der Aufkleber eine Bedruk- kungsfläche zur Verfügung, die für weitere Präsentationszwek- ke oder für andere Werbeaufdrucke genutzt werden kann.The covering means is preferably a sticker. This allows the trough to be covered in a particularly rational and cost-effective manner. In addition, the sticker provides a printing area that can be used for further presentation purposes or for other advertising prints.
Zweckmäßigerweise ist bei einer Lebensmittelverpackung mit zwei Reihen von Formvertiefungen der Trog so angeordnet, daß er sich über der Mitte zwischen diesen beiden Reihen befin- det. Es können aber auch mehrere Tröge vorgesehen sein, die dann vorzugsweise parallel zueinander angeordnet sind.In the case of food packaging with two rows of mold recesses, the trough is expediently arranged such that it is located above the middle between these two rows. det. However, several troughs can also be provided, which are then preferably arranged parallel to one another.
Zweckmäßig ist es, wenn das Deckelteil mit Haltevertiefungen versehen ist, die vorzugsweise mit dem Trog verbunden sind. Die Haltevertiefungen steifen das Deckelteil zusätzlich aus. Zudem können sie so geformt sein, daß sie mit den aufzunehmenden Lebensmittelstücken zusammenwirken, bei einem Eierkarton also insbesondere mit der Oberseite der Eier. Dadurch können unerwünschte Bewegungen der Eier in den Formvertiefungen verhindert werden, wie sie beispielsweise bei schnellen Bewegen eines Eierkartons, insbesondere beim Transport, auftreten. Ist der Trog mit den Haltevertiefungen verbunden, so hat dies ferner den Vorteil, daß ein wesentlich größerer Auf- nahmeraum bei gleichzeitig erhöhter Steifigkeit des Deckelteils entsteht.It is expedient if the cover part is provided with holding depressions which are preferably connected to the trough. The holding depressions additionally stiffen the cover part. In addition, they can be shaped in such a way that they interact with the pieces of food to be picked up, in particular with an egg carton with the top of the eggs. This can prevent undesirable movements of the eggs in the mold recesses, such as occur, for example, when an egg carton is moved quickly, particularly during transport. If the trough is connected to the holding depressions, this also has the advantage that a substantially larger receiving space is created with increased rigidity of the cover part.
Zweckmäßigerweise weisen der Trog und die Haltevertiefungen etwa die gleiche Tiefe auf. Damit wird erreicht, daß die Soh- len der jeweiligen Vertiefungen auf gleicher Höhe liegen, so daß sie insgesamt eine ebene Fläche bilden. Dies hat den Vorteil, daß das Deckelteil und damit die gesamte Lebensmittelverpackung ein ansprechendes Äußeres erhält, als dies bei unterschiedlichen Tiefen mit daraus resultierenden zerklüfteten Struktur der Sohle der Fall wäre. Der Trog kann auch eine größere Tiefe als die Haltevertiefungen aufweisen, so daß sich in dem Aufnahmeraum eine Rinne im Bereich des Trogs ausbildet. Eine solche Rinne kann einerseits für die einzulegenden Gegenstände durchaus erwünscht sein. Andererseits wirkt die Rinne zusätzlich aussteifend, so daß die Steifigkeit des Deckelteils noch weiter verbessert wird. Vorzugsweise weist der Trog und/oder die Haltevertiefungen eine Tiefe auf, die nicht größer eine maximale Nestungshöhe der Lebensmittelverpackung ist. Durch eine Begrenzung der Tiefe auf die maximale Nestungshöhe wird die Stapelbarkeit der Lebensmittelverpackungen im geöffneten, noch unbefüllten Zustand verbessert. Ein besonderer Vorteil liegt darin, daß die Lebensmittelverpackungen auch bei einem bereits durch das Abdeckmittel verschlossenen Trog gestapelt werden können. Dies ist insbesondere in dem Fall von Vorteil, wenn das Abdeckmittel ein Aufkleber, wie zum Beispiel ein Etikett ist. Dann können auch bereits etikettierte Lebensmittelverpackungen gestapelt werden. Das ermöglicht es, die Lebensmittelverpackungen bereits vor dem Befüllen zu etikettieren und mit den einzulegenden Gegenständen zu versehen. Die Nestungshöhe beträgt in der Regel zwischen 4 und 15 mm und liegt vorzugsweise zwischen 7 und 9 mm.The trough and the holding depressions expediently have approximately the same depth. This ensures that the bottoms of the respective depressions are at the same height, so that they form a flat surface overall. This has the advantage that the lid part and thus the entire food packaging is given an attractive appearance than would be the case at different depths with the resulting jagged structure of the sole. The trough can also have a greater depth than the holding recesses, so that a groove is formed in the area of the trough in the receiving space. On the one hand, such a channel can be quite desirable for the objects to be inserted. On the other hand, the channel has an additional stiffening effect, so that the rigidity of the cover part is further improved. The trough and / or the holding depressions preferably have a depth which is not greater than a maximum nesting height of the food packaging. Limiting the depth to the maximum nesting height improves the stackability of the food packaging when it is open and not yet filled. A particular advantage is that the food packaging can be stacked even with a trough already closed by the cover. This is particularly advantageous in the case when the covering means is a sticker, such as a label. Then already labeled food packaging can be stacked. This makes it possible to label the food packaging before filling it and to provide it with the objects to be inserted. The nesting height is usually between 4 and 15 mm and is preferably between 7 and 9 mm.
Vorzugsweise sind die Haltevertiefungen seitlich versetzt zu den Formvertiefungen angeordnet. Seitlich versetzt bedeutet, daß die Haltevertiefungen im Deckelteil nicht genau über den jeweiligen Formvertiefungen des Bodenteils angeordnet sind, sondern horizontal versetzt sind, so daß eine Haltevertiefung etwa in der Mitte über zwei in einer Reihe benachbarten Ver- tiefungen angeordnet ist. Bei der versetzten Anordnung reicht eine geringere Anzahl von Haltevertiefungen aus, um auf sämtliche verpackte Lebensmittelstücke in der Lebensmittelverpak- kung einzuwirken. Beispielsweise reichen bei einem Eierkarton für sechs Eier dann vier Haltevertiefungen aus. Zur weiteren Aussteifung der Haltevertiefungen kann es zweckmäßig sein, wenn die Haltevertiefungen eine Ausbuchtung an ihrer Sohle aufweisen. Diese Ausbuchtung kann konkav oder vorzugsweise konvex, d.h. nach oben gewölbt, sein.The holding recesses are preferably arranged laterally offset from the mold recesses. Laterally offset means that the holding recesses in the cover part are not arranged exactly above the respective shaped recesses of the bottom part, but are offset horizontally, so that a holding recess is arranged approximately in the middle over two recesses adjacent in a row. With the offset arrangement, a smaller number of holding depressions is sufficient to act on all packaged food items in the food packaging. For example, four holding recesses are sufficient for an egg carton for six eggs. To further stiffen the holding recesses, it can be useful if the holding recesses have a bulge on their sole exhibit. This bulge can be concave or preferably convex, ie curved upwards.
Zweckmäßigerweise sind die Haltevertiefungen als Klemmöffnun- gen und die Formvertiefungen als Klemmerhebungen ausgebildet. Zum Beispiel können die Formvertiefungen mit einem unteren Rand versehen sein, der so bemessen ist, daß er kraftschlüssig in die Klemmöffungen eingreift. Auf diese Weise läßt sich mit nur geringem zusätzlichen Aufwand die Lebensmittelverpak- kung als Klemmbaustein ausbilden.The holding recesses are expediently designed as clamping openings and the shaped recesses as clamping elevations. For example, the mold recesses can be provided with a lower edge which is dimensioned such that it engages non-positively in the clamping openings. In this way, the food packaging can be designed as a clamping module with little additional effort.
Die Erfindung wird nachfolgend unter Bezugnahme auf die in der Zeichnung dargestellten Eierkartons als Ausführungsbeispiele näher erläutert. Darin zeigen:The invention is explained in more detail below with reference to the egg cartons shown in the drawing as exemplary embodiments. In it show:

Ein erfindungsgemäßer Eierkarton ist in Fig. 1 im aufgeklappten Zustand, in Fig. 2 im geschlossenen Zustand dargestellt. Der in seiner Gesamtheit mit dem Bezugszeichen 1 bezeichnete Eierkarton umfaßt ein Unterteil 2 und ein Deckelteil 3, das über ein Biegescharnier 25 klappbar an dem Unterteil 2 befe- stigt ist, sowie einen darauf angebrachten Aufkleber 7 (siehe Fig. 3). Im geschlossenen Zustand liegt das Deckelteil 3 auf dem Unterteil 2 auf und überdeckt dieses vollständig. Durch Schwenken des Deckelteils 3 um die Achse des Biegescharniers 25 um etwa 180 ° wird das Deckelteil 3 in seine geöffnete Position gebracht. In dieser befindet sich das Deckelteil 3 etwa in einer Ebene mit dem Bodenteil 2. In dieser Stellung können mehrere Eierverpackungen raumsparend gestapelt werden.An egg carton according to the invention is shown in FIG. 1 in the opened state and in FIG. 2 in the closed state. The egg carton, designated as a whole by the reference number 1, comprises a lower part 2 and a lid part 3, which can be hinged to the lower part 2 by means of a flexible hinge 25. Stigt, and a sticker 7 attached to it (see Fig. 3). In the closed state, the cover part 3 lies on the lower part 2 and covers it completely. The cover part 3 is brought into its open position by pivoting the cover part 3 about the axis of the bending hinge 25 by approximately 180 °. In this, the lid part 3 is located approximately in one plane with the bottom part 2. In this position, several egg packagings can be stacked to save space.
Das Bodenteil 2 weist eine Mehrzahl von Formvertiefungen zur Aufnahme von Eiern auf. In dem dargestellten Ausführungsbeispiel sind die Formvertiefungen 21 in zwei parallelen Reihen zu je drei Formvertiefungen 21 angeordnet. Die Formvertiefungen 21 sind durch entsprechende Gestaltung der Wandung des Bodenteils 2 sowie durch zwei in der Mitte angeordnete Stützen 23 gebildet. Die Formvertiefungen sind so ausgeführt, daß in sie eingesetzte Eier sich nicht gegenseitig berühren. Um das Deckelteil 3 im geschlossenen Zustand zu fixieren, sind zwei Haltenasen an einer Vorderseite des Bodenteils 2 ange- ordnet.The bottom part 2 has a plurality of shape recesses for receiving eggs. In the illustrated embodiment, the mold depressions 21 are arranged in two parallel rows of three mold depressions 21 each. The recesses 21 are formed by appropriate design of the wall of the base part 2 and by two supports 23 arranged in the middle. The recesses are designed so that the eggs inserted in them do not touch each other. In order to fix the cover part 3 in the closed state, two retaining lugs are arranged on a front side of the base part 2.
Das Deckelteil 3 ist von wannenförmiger Gestalt und besteht aus einem Rückteil, einem Oberteil 31, zwei Seitenteilen 32 sowie einem Vorderteil 33. In dem Vorderteil 33 sind zwei Öffnungen 34 angeordnet, die zum Zusammenwirken mit den Nasen 24 des Bodenteils 2 bestimmt sind, um das Deckelteil 3 im geschlossenen Zustand mit dem Bodenteil 2 zu verriegeln. Das Deckelteil 3 begrenzt im geschlossenen Zustand zusammen mit dem Bodenteil 2 einen Innenraum, in dem die Eier geschützt angeordnet sind. In Fig. 2 ist die Gestaltung des Oberteils 31 des Deckelteils näher zu erkennen. Das Oberteil 31 ist von einer Oberkante 30 umgrenzt. Das Oberteil 31 ist mit vier Haltevertiefungen 36 versehen. Die Haltevertiefungen 36 sind versetzt in Bezug auf die Formvertiefungen 21 des Bodenteils 2 angeordnet, und zwar in der Weise, daß im geschlossenen Zustand des Eierkartons 1 die Haltevertiefungen 36 jeweils mittig über zwei unmittelbar in einer Reihe benachbarten Formvertiefungen 21 angeordnet sind. Bei dem in dem Ausführungsbeispiel dargestellten Eier- karton 1 mit sechs Formvertiefungen 21 sind somit viel Haltevertiefungen 36 in dem Oberteil 31 des Deckelteils 3 angeordnet. Die Haltevertiefungen 36 weisen jeweils eine Sohle 38 auf, die eine konvexe nach oben gewölbte Ausnehmung 37 beinhalten. Die Ausnehmung 37 dient zur Versteifung der Sohle 38 der Haltevertiefung 36. Mit dem Rand der Sohle 38 wird jede der Haltevertiefungen 36 stabilisierend auf die Oberseite der Eier ein, die in den reihenmäßig benachbarten Formvertiefungen 21 angeordnet sind. Es ist dazu nicht zwingend erforderlich, daß die Eier den Rand der Sohle 38 im eingesetzten Zu- stand berühren; insbesondere bei kleineren Eiern wird dies häufig nicht der Fall sein. Die Wirkung der Haltevertiefung 36 besteht vielmehr darin, eine unerwünschte Bewegung der Oberseite der Eier zu begrenzen. Dadurch können Schäden durch Aneinanderschlagen von Eiern in benachbarten Formvertiefungen 11 in Folge abrupter und grober Handhabung des Eierkartons vermieden werden. Die Haltevertiefungen 36 dienen ferner dazu, das Deckelteil 3 zusätzlich auszusteifen. Dadurch kann Eierkarton 1 die verpackten Eier besser vor Beschädigungen schützen. Außerdem verbessert sich dadurch die Stapelfähig- keit des Eierkartons 1. In Fig. 4 sind mehrere Eierkartons 1, 1', 1'' im Klemmverbund dargestellt. Ferner dargestellt ist ein weiterer Eierkarton 1*, der nicht im Klemmverbund mit den übrigen Eierkartons steht. Wie aus Fig. 4 oder im Detail auch aus Fig. 2 ersehen werden kann, weist das Unterteil 2 der Eierverpackung 1 an den jeweiligen unteren Enden der Formvertiefungen 21 eine Klemmerhebung 5 auf. Diese ist als ein umlaufender Rand der jeweiligen Formvertiefung 21 ausgebildet. An dem Deckelteil 3 sind die Haltevertiefungen 36 in der Weise ausgebildet, daß sie als Klemmöffnungen 6 fungieren. Die Abmessungen der Klemmerhebungen 5 und Klemmöffnungen 6 sind so aufeinander abgestimmt, daß die Klemmerhebungen 5 kraftschlüssig in die Klemmöffnungen 6 aufgenommen werden können. Da die Haltevertiefungen 36 den gleichen Abstand voneinander aufweisen wie die Formvertiefungen 21 mit ihren Klemmerhebungen 5, können mehrere Eierkartons 1, l1 versetzt zueinander klemmend verbunden werden. Zweckmäßigerweise ist die Oberkante 30 des Deckelteils 3 dabei soweit eingezogen, daß ihr Abstand von der nächsten Klemmöffnung 6 geringer ist als der Abstand der Klemmerhebungen 5 von einander. Dadurch ist sicher gestellt, daß bei einem versetzten Montieren eines Eierkartons 1 auf einem anderen Eierkarton 1 ' keine der Formvertiefungen 5 mit dem Oberteil 31 des Deckelteils 3 kollidiert. Ein schiefer Sitz des oberen Eierkartons 1 wird damit vermieden. Dadurch wird ein sicherer Klemmsitz erreicht.The cover part 3 is trough-shaped and consists of a rear part, an upper part 31, two side parts 32 and a front part 33. In the front part 33, two openings 34 are arranged, which are intended to cooperate with the lugs 24 of the bottom part 2 in order to Lock the lid part 3 in the closed state with the bottom part 2. In the closed state, the cover part 3, together with the base part 2, delimits an interior space in which the eggs are arranged in a protected manner. The design of the upper part 31 of the cover part can be seen in more detail in FIG. 2. The upper part 31 is delimited by an upper edge 30. The upper part 31 is provided with four holding recesses 36. The holding recesses 36 are arranged offset with respect to the shaped recesses 21 of the bottom part 2, in such a way that in the closed state of the egg carton 1, the holding recesses 36 are each arranged centrally over two directly adjacent mold recesses 21. In the egg box 1 shown in the exemplary embodiment with six shaped recesses 21, many holding recesses 36 are thus arranged in the upper part 31 of the cover part 3. The holding depressions 36 each have a sole 38, which contain a convex recess 37 which is curved upwards. The recess 37 serves to stiffen the sole 38 of the holding recess 36. With the edge of the sole 38, each of the holding recesses 36 is stabilized on the upper side of the eggs, which are arranged in the series-shaped mold recesses 21. It is not absolutely necessary for this that the eggs touch the edge of the sole 38 in the inserted state; this will often not be the case, especially with smaller eggs. Rather, the effect of the holding recess 36 is to limit unwanted movement of the top of the eggs. Damage caused by eggs beating against one another in adjacent recesses 11 as a result of abrupt and rough handling of the egg carton can thereby be avoided. The holding depressions 36 also serve to additionally stiffen the cover part 3. Egg carton 1 can thus better protect the packaged eggs from damage. This also improves the stackability of the egg carton 1. In Fig. 4 several egg boxes 1, 1 ', 1''are shown in the clamping assembly. Also shown is another egg box 1 *, which is not in a clamped connection with the other egg boxes. As can be seen from FIG. 4 or in detail also from FIG. 2, the lower part 2 of the egg packaging 1 has a clamp elevation 5 at the respective lower ends of the mold recesses 21. This is designed as a peripheral edge of the respective mold recess 21. On the cover part 3, the holding recesses 36 are formed in such a way that they act as clamping openings 6. The dimensions of the clamping elevations 5 and clamping openings 6 are coordinated with one another in such a way that the clamping elevations 5 can be non-positively received in the clamping openings 6. Since the holding recesses 36 are at the same distance from one another as the shaped recesses 21 with their clamping elevations 5, several egg boxes 1, l 1 can be connected in a staggered manner to one another. The upper edge 30 of the cover part 3 is expediently drawn in so far that its distance from the next clamping opening 6 is less than the distance of the clamping elevations 5 from one another. This ensures that when an egg carton 1 is staggered on another egg carton 1 ', none of the mold depressions 5 collide with the upper part 31 of the lid part 3. An oblique fit of the upper egg box 1 is avoided. This ensures a secure press fit.
Die versetzte Anordnung der Klemmerhebungen 5 und der Klemmöffnungen 6 bewirkt ferner, daß genau übereinander gestapelte Eierkartons 1, 1* nicht miteinander verklemmen können. Dies ist im oberen Teil der Fig. 4 zu erkennen. Das hat den Vorteil, daß gefüllte Eierkartons, die üblicherweise zur Lage- rung oder zum Verkauf direkt übereinander gestapelt sind, nicht zusammenklemmen können. Dadurch wird auf einfache, aber wirkungsvolle Weise vermieden, daß beim Entnehmen des obersten Eierkartons 1 ' versehentlich auch ein darunter befindli- eher Eierkarton 1 oder ein ganzer Stapel von Eierkartons mitbewegt wird, wodurch es zu einem Umfallen des Stapels und damit zu einer Beschädigung der Eier kommen könnte.The offset arrangement of the clamping elevations 5 and the clamping openings 6 also has the effect that egg boxes 1, 1 * stacked exactly one above the other cannot jam with one another. This can be seen in the upper part of FIG. 4. This has the advantage that filled egg boxes, which are usually or stacked directly on top of each other for sale, cannot clamp together. This avoids in a simple but effective manner that when the top egg carton 1 'is removed, an egg carton 1 located underneath or an entire stack of egg cartons is inadvertently moved as well, causing the stack to fall over and thus damage the eggs could come.
Ferner hat die versetzte Anordnung der Vorteil, daß bei genau aufeinander gestapelten Eierkartons 1, 1' die Klemmerhebungen 5 jeweils auf dem Oberteil 31 aufliegen und sich nicht über Klemmöffnungen 6 befinden, so daß sie von dem Aufkleber 7 getragen werden müssen. Der Gefahr einer Beschädigung des Aufklebers 7 durch Überlastung wird dadurch entgegengewirkt.Furthermore, the offset arrangement has the advantage that, when the egg cartons 1, 1 'are stacked exactly on top of one another, the clamping elevations 5 each rest on the upper part 31 and are not located above clamping openings 6, so that they have to be carried by the sticker 7. This counteracts the risk of the sticker 7 being damaged by overloading.
Wie weiter aus Fig. 4 ersehen werden kann, können entsprechenderweise auch mehrere Eierkartons 1, 1' ' über Eck miteinander klemmend verbunden werden. Dies ermöglicht den Aufbau von Eckstrukturen.As can further be seen from FIG. 4, a plurality of egg cartons 1, 1 ″ can correspondingly also be connected to one another by means of a corner. This enables the construction of corner structures.
Durch die Klemmerhebungen 5 an der Unterseite und die Klemmöffnungen 6 an der Oberseite können die Eierkartons 1 einer zweiten Verwendung als Klemmbausteine zugeführt werden. Da sie kostengünstig verfügbar sind und verhältnismäßig große Abmessungen aufweisen, eigenen sie sich als Spielzeug für kleine und große Kinder. Mit den Eierkartons als Klemmbausteinen können rasch und kostengünstig verhältnismäßig große Strukturen aufgebaut werden, beispielsweise Spielhäuser oder Spielburgen.By means of the clamping elevations 5 on the underside and the clamping openings 6 on the upper side, the egg cartons 1 can be fed to a second use as clamping modules. Since they are available inexpensively and have relatively large dimensions, they are suitable as toys for small and large children. With the egg boxes as clamping blocks, relatively large structures can be built quickly and inexpensively, for example playhouses or play castles.
Gemäß einem weiteren Aspekt der Erfindung ist ein Trog 4 etwa in der Mitte des Oberteils 31 des Deckelteils 3 angeordnet. Der Trog 4 ist parallel zur Achse des Biegescharniers 25 ausgerichtet und erstreckt sich über mindestens die Hälfte des Deckelteils 3, im dargestellten Beispiel etwa über ein % der Länge. In dem dargestellten Ausführungsbeispiel verbindet der Trog 4 alle vier Haltevertiefungen 36 miteinander. Dadurch entsteht ein Aufnahmeraum 40, der von oben gesehen die Gestalt eines abgerundeten Buchstaben "H" hat. Bei dem in Fig. 2 dargestellten Ausführungsbeispiel liegt eine Sohle 41 des Trogs 4 tiefer als die Sohle 38 der Haltevertiefungen 36. Da- durch entsteht innerhalb des Aufnahmeraums 40 eine Mittelrinne. Es versteht sich, daß die Sohle 41 des Trogs 4 auch höher liegen kann als die Sohle 38 der Haltevertiefungen 36. Bei dem in Fig. 4 dargestellten Ausführungsbeispiel liegt die Sohle 41 auf gleicher Höhe wie die Sohle 38 der Haltevertie- fungen 36. Der durch die Verbindung der Haltevertiefungen 36 mit dem Trog 4 entstehende Aufnahmeraum 40 ist verhältnismäßig geräumig. Er eignet sich sowohl zur Aufnahme länglicher Gegenstände, wie auch solcher Gegenstände mit unregelmäßiger Gestalt, beispielsweise einen Flaschenöffner mit seinem ver- breiterten Ende. Die Länge des Trogs 4 ist zweckmäßigerweise so gewählt, daß der aufzunehmende Gegenstand bequem hineingelegt werden kann. Die Länge braucht nicht unbedingt durch den Abstand der Haltevertiefung 36 vorgegeben zu sein, sie kann auch abhängig von den jeweiligen Anforderungen größer oder kleiner gewählt sein.According to a further aspect of the invention, a trough 4 is arranged approximately in the middle of the upper part 31 of the cover part 3. The trough 4 is aligned parallel to the axis of the bending hinge 25 and extends over at least half of the cover part 3, in the example shown approximately over a% of the length. In the exemplary embodiment shown, the trough 4 connects all four holding depressions 36 to one another. This creates a receiving space 40 which, seen from above, has the shape of a rounded letter "H". In the embodiment shown in FIG. 2, a bottom 41 of the trough 4 lies lower than the bottom 38 of the holding recesses 36. This creates a central channel within the receiving space 40. It goes without saying that the sole 41 of the trough 4 can also be higher than the sole 38 of the holding recesses 36. In the exemplary embodiment shown in FIG. 4, the sole 41 lies at the same height as the sole 38 of the holding recesses 36 the connection of the holding recesses 36 with the trough 4 resulting receiving space 40 is relatively spacious. It is suitable for receiving elongated objects as well as objects with an irregular shape, for example a bottle opener with its widened end. The length of the trough 4 is expediently chosen so that the object to be picked up can be conveniently placed therein. The length does not necessarily have to be predetermined by the spacing of the holding recess 36, it can also be chosen to be larger or smaller depending on the respective requirements.
Um im geöffneten Zustand gestapelte Eierkartons leicht voneinander trennen zu können, sind die Flanken des Trogs 4 und der Haltevertiefung 36 gegenüber der Vertikalen geneigt. Die Größe der Neigung ist abhängig von den Materialeigenschaften, insbesondere der Materialstärke und dem Reibungskoeffizient und beträgt üblicherweise zwischen 2° und 20°, vorzugsweise zwischen 6° und 9°. Damit lassen sich die gestapelten Eierkartons optimal wieder entstapeln, d.h., es ergibt sich eine gute Entnestungsfähigkeit.In order to be able to easily separate egg boxes stacked in the open state, the flanks of the trough 4 and the holding recess 36 are inclined with respect to the vertical. The size of the inclination depends on the material properties, in particular the material thickness and the coefficient of friction, and is usually between 2 ° and 20 °, preferably between 6 ° and 9 °. This means that the stacked egg boxes can be optimally unstacked again, which means that there is good denestability.
Um ein Herausfallen des in dem Aufnahmeraum 40 eingelegtenTo prevent the one inserted in the receiving space 40 from falling out
Gegenstandes beim Transport zu vermeiden, ist ein Aufkleber 7 vorgesehen. Er wird so auf das Oberteil 31 des Deckelteils 3 geklebt, daß er sich über die vier Haltevertiefungen 36 und den Trog 4 erstreckt, so daß der gesamte Aufnahmeraum 40 von dem Aufkleber 7 bedeckt ist. Der Aufkleber 7 dient aber nicht nur zum Verhindern des Herausfallens des eingelegten Gegenstandes. Er hat ferner die Funktion, den in dem Aufnahmeraum 40 eingelegten Gegenstand vor dem Auge des Benutzers zu verbergen. Damit weiß der Benutzer erst beim Abziehen des Auf- klebers 7 von dem Deckelteil des Eierkartons 1, was für einTo avoid objects during transport, a sticker 7 is provided. It is glued onto the upper part 31 of the cover part 3 such that it extends over the four holding recesses 36 and the trough 4, so that the entire receiving space 40 is covered by the sticker 7. The sticker 7 is not only used to prevent the inserted object from falling out. It also has the function of hiding the object inserted in the receiving space 40 from the user's eye. Thus, the user only knows what kind of a thing when the sticker 7 is removed from the lid part of the egg carton 1
Gegenstand sich dahinter in dem Aufnahmeraum 40 verbirgt. Dadurch wird ein durchaus erwünschter Überraschungseffekt erzielt, der Eierkarton hinterläßt bei dem Benutzer einen nachdrücklicheren und positiveren Eindruck. Der Aufkleber 7 hat den weiteren Vorteil, daß er noch eine Bedruckungsflache zur Verfügung stellt, die für Produktinformation oder Werbung genutzt werden kann. Die in Fig. 3 gezeigte Größe des Aufklebers ist an sich beliebig, solange er den Trog 4 und die Halteverbindung 36 hinreichend abdeckt. Der Aufkleber kann auch wesentlich größer ausgeführt sein, so kann seine Vorderseite bis zur Unterkante des Vorderteils 33 des Deckelteils 3 heruntergezogen sein. Object hides behind it in the receiving space 40. This creates a very desirable surprise effect, the egg carton leaves the user with a more emphatic and positive impression. The sticker 7 has the further advantage that it still provides a printing area that can be used for product information or advertising. The size of the sticker shown in FIG. 3 is arbitrary as long as it covers the trough 4 and the holding connection 36 sufficiently. The sticker can also be made much larger, so its front can be pulled down to the lower edge of the front part 33 of the cover part 3.
