Abstract

The invention relates to a cardboard folding carton, in particular for deep-frozen products, having a bottom (2), side walls (3) and a top (4). The bottom (2) and the side walls (3) are formed by erecting a blank and are joined to form a self-supporting lower carton part. According to the invention, the folding carton has a carton insert, produced from a carton blank, for the product being packed as well as an inlay (10) covering the filling opening of the carton insert. By means of spacer elements (8, 9), the carton insert is kept at a distance from the bottom (2) and from the side walls (3) of the lower carton part (1) in a way forming a hollow wall. The hollow space formed as a result is closed off at the top by rectangularly folded-off terminating tabs, formed onto the side walls (3) of the lower carton part. The inlay (10) and the top (4) form a hollow wall, which adjoins the hollow space between the carton insert and the lower carton part. <IMAGE>

Description

Die Erfindung bezieht sich gattungsgemäß auf eine Faltschachtel aus Karton, insbesondere für tiefgefrorene Produkte, mit einem Boden, Seitenwänden und einem Deckel, wobei der Boden und die Seitenwände durch Aufrichten eines Zuschnittes geformt und zu einem selbsttragenden Schachtelunterteil verbunden sind.The invention relates generically to a folding box made of cardboard, in particular for deep-frozen products, with a bottom, side walls and a lid, the bottom and the side walls being formed by erecting a blank and connected to form a self-supporting bottom part of the box.

Zum Abpacken tiefgefrorener Lebensmittel werden überwiegend Faltschachteln aus Karton eingesetzt. Zur Verbesserung der Barriereeigenschaften kann dieser Karton eine Innenbeschichtung, z. B. aus Polyäthylen oder Polypropylen, aufweisen. Die gattungsgemäße Verpackung hat eine gute Stabilität und kann mehrfarbig bedruckt werden. Insofern hat sich die Verpackung in der Praxis bewährt. Verbesserungsbedürftig ist allerdings die Kälteisolierung. So besteht beim Transport der tiefgefrorenen Produkte, beispielsweise vom Einkaufszentrum zum Verbraucherhaushalt, regelmäßig die Gefahr, daß die abgepackten Lebensmittel antauen. Auch ist die unzureichende Isolationswirkung Ursache für eine Reifbildung an den Außenflächen der in einer Kühltheke zum Verkauf ausgestellten Packungen. Dies wird von dem Verbraucher häufig als störend empfunden.Cardboard folding boxes are mainly used to pack frozen food. To improve the barrier properties, this cardboard can have an inner coating, e.g. B. made of polyethylene or polypropylene. The generic packaging has good stability and can be printed in multiple colors. In this respect, the packaging has proven itself in practice. However, the cold insulation is in need of improvement. Thus, when transporting the frozen products, for example from the shopping center to the consumer household, there is a regular risk that the packaged food will thaw. The inadequate insulation effect is also the reason for the formation of frost on the outer surfaces of the packs on display in a refrigerated counter. This is often perceived as annoying by the consumer.

Der Erfindung liegt die Aufgabe zugrunde, die Wärmeisolierung einer gattungsgemäßen Faltschachtel zu verbessern.The invention has for its object to improve the thermal insulation of a generic folding box.

Die Faltschachtel der eingangs beschriebenen Art ist erfindungsgemäß gekennzeichnet durch einen aus einem Kartonzuschnitt gefertigten Schachteleinsatz für das Verpackungsgut sowie eine die Füllöffnung des Schachteleinsatzes abdeckende Einlage, wobei der Schachteleinsatz von Distanzelementen mit hohlwandbildendem Abstand zum Boden und zu den Seitenwänden des Schachtelunterteiles gehalten ist und der dadurch gebildete Hohlraum durch rechtwinklig abgefaltete, an die Seitenwände des Schachtelunterteiles angeformte Abschlußlaschen oberseitig abgeschlossen ist und wobei die Einlage und der Deckel eine Hohlwand bilden, die an den Hohlraum zwischen dem Schachteleinsatz und dem Schachtelunterteil angrenzt. Der Schachteleinsatz und die Einlage bestehen aus Karton, wobei übliche Innenbeschichtungen zur Verbesserung der Barriereeigenschaften vorgesehen sein können. - Erfindungsgemäß sind alle Schachtelflächen der geschlossenen Faltschachtel als Hohlwände ausgebildet, die unter Vermeidung von Kältebrücken aneinander angrenzen. Die Erfindung nutzt die geringe Wärmeleitfähigkeit in stehenden Luftschichten. Ein Luftspalt von einem oder wenigen Millimetern ist ausreichend, um die Wärmeisolation in beachtlichem Maße zu verbessern.The folding box of the type described at the outset is characterized according to the invention by a box insert made of a cardboard blank for the packaged goods and an insert covering the filling opening of the box insert, the box insert being held by spacer elements with a cavity-forming distance from the floor and the side walls of the bottom part of the box and the resultant formed thereby Cavity is closed on the upper side by right-angled folding tabs formed on the side walls of the lower part of the box and the insert and the cover form a hollow wall which adjoins the cavity between the box insert and the lower part of the box. The box insert and the insert are made of cardboard, and customary inner coatings can be provided to improve the barrier properties. - According to the invention, all of the box surfaces of the closed folding box are designed as hollow walls which adjoin one another while avoiding cold bridges. The invention uses the low thermal conductivity in standing layers of air. An air gap of one or a few millimeters is sufficient to improve the thermal insulation considerably.

Im Rahmen der Erfindung liegt es, die Distanzelemente als separate Bauteile auszubilden. Aus fertigungstechnischen Gründen ist es jedoch vorteilhaft, an den Zuschnitten, aus denen das Schachtelunterteil und/oder der Schachteleinsatz hergestellt werden, Ausbildungen vorzusehen, die zu Distanzelementen abfaltbar sind. Eine sowohl in wärmetechnischer als auch in fertigungstechnischer Hinsicht vorteilhafte Ausbildung der Erfindung sieht vor, daß die Abschlußlaschen des Schachtelunterteiles nach innen umstülpbare Wandflächen aufweisen, die als Distanzelemente an Seitenflächen des Schachteleinsatzes anliegen, oder daß alternativ die Abschlußlaschen des Schachtelunterteiles mit umgefalteten Anschlußflächen des Schachteleinsatzes zu Distanzelementen verbunden sind. Die auf diese Weise gebildeten Distanzelemente besitzen ausreichende Steifigkeit. Ferner werden Kältebrücken im Deckelbereich der Faltschachtel zuverlässig vermieden. Der Schachteleinsatz besteht zweckmäßigerweise aus einem aufrichtbaren Zuschnitt, der eine Bodenfläche, angeformte Seitenflächen und an die Seitenflächen angeschlossene Klebelaschen aufweist. Die Klebelaschen können dabei zugleich als Distanzelemente ausgebildet werden, die den Abstand des Schachteleinsatzes von dem Boden des Schachtelunterteiles definieren. Dazu lehrt die Erfindung, daß die Klebelaschen nach dem Aufrichten des Schachteleinsatzes jeweils eine benachbarte Seitenfläche außenseitig umfassen und mit Vorsprüngen ausgebildet sind, die fußartig auf dem Boden des Schachtelunterteiles stehende Distanzelemente bilden. Es versteht sich, daß die fußartig auf dem Boden des Schachtelunterteiles stehenden Distanzelemente durch Doppelfaltung oder durch Aufkleben von Papp- oder Kartonstreifen verstärkt werden können.It is within the scope of the invention to design the spacer elements as separate components. For manufacturing reasons, however, it is advantageous to provide designs on the blanks from which the bottom part of the box and / or the box insert are made, which can be folded down to form spacer elements. An embodiment of the invention which is advantageous both in terms of heat technology and in terms of production technology provides that the end flaps of the bottom part of the box have inward-turning wall surfaces which lie as spacing elements on side surfaces of the bottom part of the box, or alternatively the end flaps of the bottom part of the box with folded-over connecting surfaces of the box insert to spacer elements are connected. The spacer elements formed in this way have sufficient rigidity. Cold bridges in the lid area of the folding box are also reliably avoided. The box insert expediently consists of an erectable blank which has a bottom surface, molded side surfaces and adhesive tabs connected to the side surfaces. The adhesive tabs can at the same time be designed as spacer elements which define the distance of the box insert from the bottom of the bottom part of the box. To this end, the invention teaches that the adhesive flaps each comprise an adjacent side surface on the outside after erecting the box insert and are formed with projections which form spacer elements standing on the bottom of the box bottom part in the manner of a foot. It goes without saying that the spacer elements standing on the bottom of the bottom part of the box can be reinforced by double folding or by gluing cardboard or cardboard strips.

Die Einlage besteht aus einem Kartonzuschnitt mit winklig abfaltbaren Flanschflächen, die auf dem Schachtelunterteil aufliegen, oder alternativ aus einem Kartonzuschnitt mit einer in den Schachteleinsatz einsetzbaren Grundfläche und daran angeformten Laschen, wobei die Laschen zu einem umlaufenden Kragen aufrichtbar sind, der an den Seitenflächen des Schachteleinsatzes anliegt und die zwischen dem Deckel und der Grundfläche des Schachteleinsatzes gebildete Hohlwand seitlich abschließt. Der Deckel ist zweckmäßigerweise als Haube mit Seitenteilen ausgebildet und wird aus einem separaten Kartonzuschnitt hergestellt.The insert consists of a cardboard blank with angularly foldable flange surfaces that rest on the bottom part of the box, or alternatively of a cardboard blank with a base that can be inserted into the box insert and tabs molded onto it, whereby the tabs can be erected to form a circumferential collar on the side surfaces of the box insert abuts and laterally closes off the hollow wall formed between the lid and the base of the box insert. The lid is expediently designed as a hood with side parts and is produced from a separate cardboard blank.

Die erfindungsgemäße Faltschachtel zeichnet sich durch eine gute Wärmedämmung aus, was insbesondere im Hinblick auf das Verpacken tiefgefrorener Produkte vorteilhaft ist, Kältebrücken, die den Gebrauchswert der Faltschachtel beeinträchtigen, sind nicht vorhanden. Die Außenfläche der erfindungsgemäßen Faltschachtel ist, da keine Sonderwerkstoffe eingesetzt werden, mehrfarbig - wie in der Praxis üblich - bedruckbar. Zur Herstellung der Faltschachtel kann auf bekannte, automatisierte Vorrichtungen zurückgegriffen werden.The folding box according to the invention is characterized by good thermal insulation, which is particularly advantageous with regard to the packaging of deep-frozen products. Cold bridges which impair the practical value of the folding box are not present. Since no special materials are used, the outer surface of the folding box according to the invention can be printed in multiple colors, as is customary in practice. Known, automated devices can be used to produce the folding box.

Die in den Figuren dargestellte Faltschachtel besteht aus Karton und ist insbesondere für tiefgefrorene Produkte bestimmt. Zum grundsätzlichen Aufbau gehören ein Schachtelunterteil 1 mit Boden 2 und Seitenwänden 3 sowie ein Deckel 4. Der Boden 2 und die Seitenwände 3 sind durch Aufrichten eines Zuschnittes 5 geformt und durch Laschen 6, die an die Seitenwände 3 angeschlossen sind, zu dem formstabilen Schachtelunterteil 1 verbunden. Den Fig. 1 und 2 sowie 7 entnimmt man, daß in dem Schachtelunterteil 1 ein Schachteleinsatz 7 für die Aufnahme des abzupackenden Produktes angeordnet ist. Der Schachteleinsatz 7 ist von Distanzelementen 8, 9 mit hohlwandbildendem Abstand zum Boden 2 und zu den Seitenwänden 3 gehalten. Auf dem Schachteleinsatz 7, der einen Boden aufweist und oben offen ist, ist die Einlage 10 mit hohlwandbildendem Abstand zum Deckel 4 angeordnet. Der Fig. 1 entnimmt man, daß sämtliche Schachtelaußenflächen als Hohlwände ausgebildet sind.The folding box shown in the figures consists of cardboard and is particularly intended for frozen products. The basic structure includes a bottom box part 1 with bottom 2 and side walls 3 and a lid 4. Bottom 2 and side walls 3 are formed by erecting a blank 5 and by tabs 6, which are connected to side walls 3, to form stable bottom box part 1 connected. 1 and 2 and 7 it can be seen that a box insert 7 is arranged in the bottom part 1 of the box for receiving the product to be packaged. The box insert 7 is held by spacer elements 8, 9 with a cavity wall-forming distance from the bottom 2 and from the side walls 3. On the box insert 7, which has a bottom and is open at the top, the insert 10 is arranged at a distance from the lid 4 forming a hollow wall. 1 shows that all of the outer box surfaces are designed as hollow walls.

Aus einer zusammenschauenden Betrachtung der Fig. 2 und 3 erkennt man, daß der das Schachtelunterteil 1 bildende Zuschnitt 5 Abschlußlaschen 11 aufweist, die an die Oberkante der Seitenwände 3 anschließen. Die Abschlußlaschen 11 decken die zwischen dem Schachtelunterteil 1 und dem Schachteleinsatz 7 gebildeten Hohlwände oberseitig ab. Sie weisen ferner nach innen umstülpbare Wandflächen auf, die als Distanzelemente 8 an den Seitenflächen des Schachteleinsatzes 7 anliegen. Die Ausführungsform gemäß Fig. 7 unterscheidet sich dadurch, daß die Abschlußlaschen 11 des Schachtelunterteiles 1 mit umgefalteten Anschlußflächen 11' des Schachteleinsatzes 7 zu Distanzelementen 8 verbunden sind. Aus einer zusammenschauenden Betrachtung der Fig. 7 bis 9 wird dies ohne weiteres deutlich.2 and 3, it can be seen that the blank forming the lower part 1 of the box 5 has end flaps 11 which connect to the upper edge of the side walls 3. The end flaps 11 cover the hollow walls formed between the lower box part 1 and the box insert 7 on the upper side. They furthermore have wall surfaces which can be turned inside and which rest as spacing elements 8 on the side surfaces of the box insert 7. The embodiment according to FIG. 7 differs in that the end flaps 11 of the lower box part 1 are connected to folded-over connection surfaces 11 'of the box insert 7 to form spacing elements 8. This is readily apparent from an overall view of FIGS. 7 to 9.

Der Schachteleinsatz 7 besteht aus einem aufrichtbaren Zuschnitt 12, der eine Bodenfläche 13, angeformte Seitenflächen 14 und an die Seitenflächen 14 angeschlossene Klebelaschen 15 aufweist. In der Zusammenschau der Fig. 2 oder 7 und 4 erkennt man, daß die Klebelaschen 15 nach dem Aufrichten des Schachteleinsatzes 7 jeweils eine benachbarte Seitenfläche 14 außenseitig umfassen. Die Klebelaschen 15 sind ferner mit Vorsprüngen ausgebildet, die fußartig auf dem Boden 2 des Schachtelunterteiles 1 stehende Distanzelemente 9 bilden. Aus den Fig. 2 und 5 bis 7 ist ohne weiteres ersichtlich, daß die Einlage 10 aus einem Zuschnitt 16 mit winklig abfaltbaren Flanschflächen 17 besteht, die auf dem Schachtelunterteil 1 aufliegen, und daß der Deckel 4 als Haube mit Seitenteilen 18 ausgebildet ist und ebenfalls aus einem ebenen Zuschnitt 19 hergestellt wird. Gemäß Fig. 10 kann die Einlage 10 alternativ auch aus einem Zuschnitt mit einer in den Schachteleinsatz 7 einsetzbaren Grundfläche 20 und daran angeformten Laschen 17' bestehen, wobei die Laschen 17' zu einem umlaufenden Kragen aufrichtbar sind, der an den Seitenflächen 14 des Schachteleinsatzes anliegt und die zwischen dem Deckel 4 und der Grundfläche 20 des Schachteleinsatzes gebildete Hohlwand seitlich abschließt. Diese Art der Einlage kann sowohl bei der in Fig. 2 als auch bei der in Fig. 7 dargestellten Faltschachtel verwendet werden. Der umlaufende Kragen führt zu einer besseren Kammerung des Luftvolumens in der Hohlwand und trägt vorteilhaft zur Wärmedämmung bei. - Sämtliche Zuschnitte 5, 12, 16, 19 bestehen aus Karton.The box insert 7 consists of an erectable blank 12 which has a bottom surface 13, molded side surfaces 14 and adhesive tabs 15 connected to the side surfaces 14. 2 or 7 and 4 it can be seen that the adhesive tabs 15 each comprise an adjacent side face 14 on the outside after the box insert 7 has been erected. The adhesive tabs 15 are also formed with projections, which form foot-like spacer elements 9 on the bottom 2 of the lower box part 1. 2 and 5 to 7 it is readily apparent that the insert 10 consists of a blank 16 with angularly foldable flange surfaces 17 which rest on the bottom part 1 of the box, and that the lid 4 is designed as a hood with side parts 18 and also is produced from a flat blank 19. 10, the insert 10 can alternatively also consist of a blank with a base 20 that can be inserted into the box insert 7 and tabs 17 'formed thereon, the tabs 17' being erectable to form a circumferential collar which bears against the side surfaces 14 of the box insert and the hollow wall formed between the lid 4 and the base 20 of the box insert laterally. This type of insert can be used both in the case of the folding box shown in FIG. 2 and in the case of FIG. 7. The circumferential collar leads to a better chambering of the air volume in the cavity wall and advantageously contributes to thermal insulation. - All blanks 5, 12, 16, 19 are made of cardboard.

Die in den Figuren dargestellte Faltschachtel ist in der folgenden Weise herstellbar:

  • Zunächst wird das Schachtelunterteil 1 durch Aufrichten des in Fig. 3 bzw. 8 dargestellten Zuschnittes 5 geformt. Die Laschen 6 werden mit den benachbarten Seitenwänden 3, vorzugsweise mit Heißleim, verklebt. Danach werden die Abschlußlaschen 11 umgeweicht. Im nächsten Arbeitsgang wird der Schachteleinsatz 7 durch Aufrichten des aus Fig. 4 bzw. 9 ersichtlichen Zuschnittes 12 geformt. Die Klebelaschen 15 werden außenseitig mit den benachbarten Seitenflächen 14 verklebt. Die Klebelaschen 15 bilden zugleich vier fußartige Distanzelemente 9, die den hohlwandbildenden Abstand zum Boden 2 des Schachtelunterteiles 1 definieren. Der formstabile Schachteleinsatz 7 wird in das Schachtelunterteil 1 eingesetzt und ggf. mit diesem verklebt. Dabei bilden sich sowohl seitliche als auch bodenseitige Hohlwände. Im letzten Arbeitsgang wird die Einlage 10 in das Schachtelunterteil 1 eingelegt sowie der Deckel 4 aufgebracht. Der Spaltraum zwischen Deckel 4 und Einlage 10 bildet ebenfalls eine Hohlwand.
The folding box shown in the figures can be produced in the following way:
  • First, the lower box part 1 is formed by erecting the blank 5 shown in FIGS. 3 and 8. The tabs 6 are glued to the adjacent side walls 3, preferably with hot glue. The end flaps 11 are then re-soaked. In the next step, the box insert 7 is formed by erecting the blank 12 shown in FIGS. 4 and 9. The adhesive tabs 15 are glued on the outside to the adjacent side surfaces 14.
