Definitions
- the invention relates to a folding box made of a liquid-tight, at least on the inside heat-sealable coated cardboard composite material, in particular Al-laminated cardboard composite material, with a flat bottom folded in one piece, which is closed by at least one flat-lying seam, in particular a web seam, and two sealed and sealed all over , triangular folding pockets.
- Folding box packs of this type with differently designed bottoms are known (DT 25 20 401 C2; EP 0093 849 A2; EP 0 133 863 B1). These folding boxes are made from a blank or from a roller conveyor or from a jacket, with the floor being heat-sealed by means of ultrasound, induction, heat pulses, infrared radiation or hot air. If such folding box packs are intended for the aseptic packaging of goods, it is customary to include them before filling to apply a full surface to a liquid or vapor sterilizing medium on the inside. This sterilizing medium must then be completely removed from the package. In order for this to be possible, the triangular folding pockets must be sealed over the entire surface to avoid nests in the pack. This sealing can best be achieved with IR radiation or hot air. In this case must be applied to each other to be sealed areas because of the significantly higher than 100 o C lying melting point of the heat-sealable coating with hot air at more than 100 o C.
- the invention has for its object to provide a package of the type mentioned, in which there is no blistering of the inside of the cardboard material when the bottom is activated with heat, even if the activation with a higher temperature than for the heat seal is essential required.
- a folding box pack of the type mentioned in that at least the inside, heat-sealable coating of the fields to be sealed are perforated into the carton. These are primarily the inner fields of the triangular folding pockets. Preferably, however, the outer fields adjoining these inner fields should also be perforated.
- the invention is based on the knowledge that the formation of bubbles is due to moisture present in the cardboard composite material, which increases the vapor pressure in the cardboard material in particular at an activation temperature which is well above 100 ° C. in such a way that with a dense outer coating, as is the case, for example, with the purpose of Better printability on the outside with a cardboard box equipped with a line or, in the case of a cardboard coated on both sides, water vapor escapes to the inside of the composite and leads to the formation of bubbles and leaks.
- the inner fields are particularly affected by this bubble formation, i.e.
- the large areas to be activated that are not are directly delimited by a cutting edge while in the case of outer fields, that is to say in the areas to be activated which lie directly on a cutting edge, they are significantly smaller and do not even occur in the case of correspondingly narrow outer fields running parallel to the cutting edge and adjacent to it, since in These outer fields allow the steam to escape through the open cut edges.
- outer fields that is to say in the areas to be activated which lie directly on a cutting edge, they are significantly smaller and do not even occur in the case of correspondingly narrow outer fields running parallel to the cutting edge and adjacent to it, since in These outer fields allow the steam to escape through the open cut edges.
- such a vapor pressure cannot generally build up because the water vapor which forms when the fields are activated with heat can escape to the outside via the perforation which is initially still exposed.
- the activation temperature is not critical, which means that it is not important to keep the temperature within narrow limits.
- the cardboard composite material comprises coated cardboard and / or the inner or outer coating has only a slight adhesion to the cardboard, it may be advantageous to perforate the outside of the composite material in the area of the fields to be sealed into the cardboard, to prevent blistering on the outside.
- the blank Before the folding box pack is formed, the blank is provided with folding lines 1, as shown in the drawing.
- the heat-sealable coating and the aluminum foil are perforated on the inside, at least in the inner fields 2 hatched in FIG. 1a for the formation of the triangular folding pockets 3, but preferably also in the hatched outer fields 4 for the web seam 5 in FIG. 1b.
- the composite material is also perforated from the outside in the inner fields 2 shown hatched in FIG. 1c and in the outer fields 4 shown hatched in FIG. 1d. From FIG. 1e, the bottom area of blanks with the inner and outer fields 2, 4 to be activated on both sides for the bottom sealing is shown.
- FIGS. 2a to 2e and 3a to 3e show different, different embodiments of blanks for folding box packs with a field division corresponding to FIG. 1.
- FIGS. 4 to 7 show the bottom area of the different blanks in the individual manufacturing steps.
- FIGS. 4 and 5 correspond to the cut according to FIG. 1
- FIG. 6 corresponds to the cut according to FIG. 2
- FIG. 7 corresponds to the cut according to FIG. 3.
- the blank prepared in this way is first formed into a tube with a rectangular cross section, as shown in FIGS. 4f, 5f, 6f and 7f, which show the bottom area in the activation position. Thereafter, the hatched fields of the bottom in FIGS. 1 to 3 are activated and the bottom is formed by folding in the direction of the arrows from FIGS. 4f, 5f, 6f and 7f.
- the triangular folding pockets are formed, as can be seen in FIGS. 4g, 5g and 7g, and the hatched areas are folded in the bottom of the pack and sealed, if necessary, so flat that they are covered towards the inside and outside of the pack. 4a show the finished bottom of a blank according to FIGS. 1a to 1e, FIG.

Abstract
Description
Die Erfindung bezieht sich auf eine Faltschachtel aus einem flüssigkeitsdichten, mindestens innenseitig heißsiegelfähig beschichteten Kartonverbundmaterial, insbesondere Al-kaschierten Kartonverbundmaterial, mit einem einstückig angefalteten flachen Boden, der durch mindestens eine flach anliegende Naht, insbesondere eine Stegnaht, verschlossen ist und zwei flachliegend und vollflächig versiegelte, dreieckige Falttaschen umfaßt.The invention relates to a folding box made of a liquid-tight, at least on the inside heat-sealable coated cardboard composite material, in particular Al-laminated cardboard composite material, with a flat bottom folded in one piece, which is closed by at least one flat-lying seam, in particular a web seam, and two sealed and sealed all over , triangular folding pockets.
Faltschachtelpackungen dieser Art mit unterschiedlich ausgebildeten Böden sind bekannt (DT 25 20 401 C2; EP 0093 849 A2; EP 0 133 863 B1). Diese Faltschachteln werden aus einem Zuschnitt oder aus einer Rollenbahn oder aus einem Mantel hergestellt, wobei die Heißsiegelung des Bodens durch Ultraschall, Induktion, Wärmeimpuls, Infrarotstrahlung oder Heißluft erfolgt. Sofern solche Faltschachtelpackungen für die aseptische Verpackung von Gütern bestimmt sind, ist es üblich, sie vor dem Füllen mit einem flüssigen oder dampfförmigen Sterilisiermedium vollflächig auf der Innenseite zu beaufschlagen. Dieses Sterilisiermedium muß dannach vollständig aus der Packung entfernt werden. Damit dies möglich ist, müssen zur Vermeidung von Nestern in der Packung die dreieckigen Falttaschen vollflächig versiegelt sein. Diese Versiegelung läßt sich am besten mit IR-Strahlung oder Heißluft erreichen. Dabei müssen die miteinander zu versiegelnden Bereiche wegen des deutlich über 100oC liegenden Schmelzpunktes der heißsiegelfähigen Beschichtung mit Heißluft von weit über 100oC beaufschlagt werden.Folding box packs of this type with differently designed bottoms are known (DT 25 20 401 C2; EP 0093 849 A2; EP 0 133 863 B1). These folding boxes are made from a blank or from a roller conveyor or from a jacket, with the floor being heat-sealed by means of ultrasound, induction, heat pulses, infrared radiation or hot air. If such folding box packs are intended for the aseptic packaging of goods, it is customary to include them before filling to apply a full surface to a liquid or vapor sterilizing medium on the inside. This sterilizing medium must then be completely removed from the package. In order for this to be possible, the triangular folding pockets must be sealed over the entire surface to avoid nests in the pack. This sealing can best be achieved with IR radiation or hot air. In this case must be applied to each other to be sealed areas because of the significantly higher than 100 o C lying melting point of the heat-sealable coating with hot air at more than 100 o C.
Bei dieser Aktivierung der miteinander zu versiegelnden Bereiche mit Heißluft hat sich gezeigt, daß es an der mit Wärme aktivierten Innenseite des Kartonverbundmaterials zu einer Blasenbildung kommt, die die Gefahr von Undichtigkeiten mit sich bringt. Diese Erscheinung ist insbesondere ausgeprägt bei innenseitig mit Al-kaschiertem Kartonverbundmaterial, weil es in diesem Fall zu einer Verwerfung der Blasen und dadurch beim Siegeln vermehrt zu Undichtigkeiten im Packungsboden kommt. Es wurde gefunden, daß die Blasenbildung besonders stark in den Innenfeldern, das sind die mit Abstand von den Schnittkanten liegenden Felder, und weniger stark in den Außenfeldern, daß sind die an den Schnittkanten angrenzenden Felder, auftritt. Es wurde ferner gefunden, daß das Ausmaß solcher Fehler gering gehalten werden kann, wenn mit einer möglichst niedrigen Aktivierungstemperatur gearbeitet wird. Eine niedrige Aktivierungstemperatur erschwert allerdings das vollflächige Versiegeln der aktivierten Bereiche.This activation of the areas to be sealed with hot air has shown that there is a bubble formation on the inside of the cardboard composite material which is activated with heat, which entails the risk of leaks. This phenomenon is particularly pronounced in the case of cardboard composite material laminated with Al on the inside, because in this case the bubbles are warped and, as a result, leaks in the packaging base increase. It was found that the blistering occurs particularly strongly in the inner fields, that is, the fields lying at a distance from the cut edges, and less strongly in the outer fields, that is, the fields adjacent to the cut edges. It has also been found that the extent of such errors can be kept to a minimum if the activation temperature is as low as possible. A low activation temperature makes it difficult to seal the activated areas over the entire surface.
Um einerseits die Fehlerquote beim Heißversiegeln möglichst gering zu halten und andererseits noch ein sicheres vollflächiges Versiegeln der aktivierten Bereiche zu gewährleisten, kann mit einer verhältnismäßig hohen Aktivierungstemperatur, bei der es gerade noch nicht zu einer Blasenbildung kommt, dann gearbeitet werden, wenn es gelingt, die Aktivierungstemperatur in engen Toleranzen zu halten. Das Einhalten solcher Toleranzen bedeutet aber einen erhöhten Aufwand in der Fertigung.In order to keep the error rate during heat sealing as low as possible on the one hand and on the other hand to guarantee a safe full-surface sealing of the activated areas, a relatively high one can Activation temperature at which bubbles do not yet form can be worked if the activation temperature can be kept within narrow tolerances. Adhering to such tolerances means an increased effort in production.
Der Erfindung liegt die Aufgabe zugrunde, eine Packung der eingangs genannten Art zu schaffen, bei der es bei der Aktivierung des Bodens mit Wärme zu einer Blasenbildung der Innenseite des Kartonmaterials auch dann nicht kommt, wenn die Aktivierung mit einer höheren Temperatur als für die Heißsiegelung unbedingt erforderlich erfolgt.The invention has for its object to provide a package of the type mentioned, in which there is no blistering of the inside of the cardboard material when the bottom is activated with heat, even if the activation with a higher temperature than for the heat seal is essential required.
Diese Aufgabe wird erfindungsgemäß bei einer Faltschachtelpackung der eingangs genanten Art dadurch gelöst, daß zumindest die innenseitige, heißsiegelfähige Beschichtung der zu versiegelnden Felder bis in den Karton hinein perforiert sind. Dies sind vor allem die Innenfelder der dreieckigen Falttaschen. Vorzugsweise sollten aber auch die an diese Innenfelder angrenzenden Außenfelder perforiert sein.This object is achieved in a folding box pack of the type mentioned in that at least the inside, heat-sealable coating of the fields to be sealed are perforated into the carton. These are primarily the inner fields of the triangular folding pockets. Preferably, however, the outer fields adjoining these inner fields should also be perforated.
Die Erfindung basiert auf der Kenntnis, daß die Blasenbildung auf im Kartonverbundmaterial vorhandene Feuchtigkeit zurückzuführen ist, die insbesondere bei weit über 100oC liegenden Aktivierungstemperatur an den Dampfdruck im Kartonmaterial derart erhöht, daß bei dichter Außenbeschichtung, wie sie zum Beispiel bei einem zum Zwecke der besseren Bedruckbarkeit auf der Außenseite mit einem Strich ausgestatteten Karton oder bei einem beidseitig beschichteten Karton gegeben ist, Wasserdampf zur Verbundinnenseite entweicht und hier zur Blasenbildung und Undichtigkeiten führt. Von dieser Blasenbildung sind vor allem die Innenfelder betroffen, das heißt die großflächigen, zu aktivierenden Bereiche, die nicht unmittelbar von einer Schnittkante begrenzt sind, während sie bei Außenfeldern, das heißt bei den zu aktivierenden Bereichen, die direkt an einer Schnittkante liegen, deutlich geringer ist und bei entsprechend schmalen, parallel zur Schnittkante und an dieser angrenzend verlaufenden Außenfeldern gar nicht auftritt, da bei diesen Außenfeldern der Dampf über die offenen Schnittkanten entweichen kann. Bei der Erfindung kann ein solcher Dampfdruck sich generell nicht aufbauen, weil der bei der Aktivierung der Felder mit Wärme sich bildende Wasserdampf über die zunächst noch freiliegende Perforation nach außen entweichen kann. Die Aktivierungstemperatur ist unkritisch, das heißt, das es nicht darauf ankommt, die Temperatur in engen Grenzen zu halten. Versuche haben gezeigt, daß es auch dann nicht zu einer Blasenbildung an der Innenseite des Kartonverbundmaterials kommt, wenn die Aktivierungstemperatur sogar um mehr als 15oC über die heute übliche Aktivierungstemperatur von zum Beispiel 360oC hinausgeht. Die Perforation an der fertigen Packung beeinträchtigt nicht deren Einsatz, da sie so gewählt werden kann, daß sie eingefaltet und eingesiegelt wird, so daß sie vor Schmutz geschützt ist und über sie auch keine Feuchtigkeit in das Verbundmaterial eindringen kann.The invention is based on the knowledge that the formation of bubbles is due to moisture present in the cardboard composite material, which increases the vapor pressure in the cardboard material in particular at an activation temperature which is well above 100 ° C. in such a way that with a dense outer coating, as is the case, for example, with the purpose of Better printability on the outside with a cardboard box equipped with a line or, in the case of a cardboard coated on both sides, water vapor escapes to the inside of the composite and leads to the formation of bubbles and leaks. The inner fields are particularly affected by this bubble formation, i.e. the large areas to be activated that are not are directly delimited by a cutting edge, while in the case of outer fields, that is to say in the areas to be activated which lie directly on a cutting edge, they are significantly smaller and do not even occur in the case of correspondingly narrow outer fields running parallel to the cutting edge and adjacent to it, since in These outer fields allow the steam to escape through the open cut edges. In the invention, such a vapor pressure cannot generally build up because the water vapor which forms when the fields are activated with heat can escape to the outside via the perforation which is initially still exposed. The activation temperature is not critical, which means that it is not important to keep the temperature within narrow limits. Experiments have shown that there is no blistering on the inside of the cardboard composite material even if the activation temperature even exceeds the current activation temperature of, for example, 360 ° C. by more than 15 ° C. The perforation on the finished package does not impair its use, since it can be chosen so that it is folded in and sealed in, so that it is protected against dirt and no moisture can penetrate into the composite material.
Bei Bedarf, zum Beispiel wenn das Kartonverbundmaterial gestrichenen Karton umfaßt und/oder die Innen- oder Außenbeschichtung nur eine geringe Haftung zum Karton aufweist, kann es vorteilhaft sein, auch die Außenseite des Verbundmaterials im Bereich der einzusiegelnden Felder bis in den Karton hinein zu perforieren, um auch an der Außenseite eine Blasenbildung zu verhindern.If required, for example if the cardboard composite material comprises coated cardboard and / or the inner or outer coating has only a slight adhesion to the cardboard, it may be advantageous to perforate the outside of the composite material in the area of the fields to be sealed into the cardboard, to prevent blistering on the outside.

In den Figuren 4 bis 7 ist der Bodenbereich der unterschiedlichen Zuschnitte in den einzelnen Fertigungsschritten dargestellt. Dabei entsprechen die Figuren 4 und 5 dem Zuschnitt gemäß Figur 1, die Figur 6 dem Zuschnitt gemäß Figur 2 und die Figur 7 dem Zuschnitt gemäß Figur 3.FIGS. 4 to 7 show the bottom area of the different blanks in the individual manufacturing steps. FIGS. 4 and 5 correspond to the cut according to FIG. 1, FIG. 6 corresponds to the cut according to FIG. 2 and FIG. 7 corresponds to the cut according to FIG. 3.
Der so vorbereitete Zuschnitt wird zunächst zu einem Schlauch mit rechteckförmigem Querschnitt geformt, wie in den Figuren 4f,5f,6f und 7f, die den Bodenbereich in der Aktivierposition zeigen, dargestellt ist. Danach werden die in Figur 1 bis 3 schraffiert angelegten Felder des Bodens aktiviert und der Boden durch Faltung in Richtung der Pfeile aus den Figuren 4f,5f,6f und 7f geformt. Dabei werden die dreieckigen Falttaschen gebildet, wie aus den Figuren 4g,5g und 7g hervorgeht, und die schraffiert angelegten Bereiche im Packungsboden eingefaltet und gegebenenfalls so flach eingesiegelt, daß sie zum Packungsinneren und auch zum Packungsäußeren hin abgedeckt sind. Dabei zeigen Figur 4a den fertigen Boden eines Zuschnitts gemäß Figur 1a bis 1e, Figur 4h' den fertigen Boden eines Zuschnitts gemäß Figur 1b oder 1d, Figuren 5h und 5h' den fertigen Boden eines Zuschnitts gemäß Figur 1b, Figur 6h den fertigen Boden eines Zuschnitts gemäß Figuren 2a bis 2e und Figur 7h den fertigen Boden eines Zuschnitts gemäß Figur 3a bis 3e. In Figur 5h sind die dreieckigen Falttaschen 3 seitlich nach außen und in Figur 5h' auf den Packungsboden geklappt.The blank prepared in this way is first formed into a tube with a rectangular cross section, as shown in FIGS. 4f, 5f, 6f and 7f, which show the bottom area in the activation position. Thereafter, the hatched fields of the bottom in FIGS. 1 to 3 are activated and the bottom is formed by folding in the direction of the arrows from FIGS. 4f, 5f, 6f and 7f. The triangular folding pockets are formed, as can be seen in FIGS. 4g, 5g and 7g, and the hatched areas are folded in the bottom of the pack and sealed, if necessary, so flat that they are covered towards the inside and outside of the pack. 4a show the finished bottom of a blank according to FIGS. 1a to 1e, FIG. 4h 'shows the finished bottom of a blank according to FIG. 1b or 1d, FIGS. 5h and 5h' show the finished bottom of a blank according to FIG. 1b, FIG. 6h shows the finished bottom of a blank according to FIGS. 2a to 2e and FIG. 7h the finished base of a blank according to FIGS. 3a to 3e. In FIG. 5h, the triangular folding pockets 3 are folded out laterally and in FIG. 5h 'on the package bottom.
Es versteht sich, daß die Art des Zuschnitts gemäß Figur 3 bzw. Figur 7 nur bei einer Faltschachtelpackung mit quadratischer Bodenfläche zur Anwendung kommen wird.It goes without saying that the type of cutting according to FIG. 3 or FIG. 7 will only be used in the case of a folding box with a square base area.
