Definitions
- the invention relates to a folding carton with a foldable outer carton and an inner side of the carton lying, foldable support ring, wherein side walls of the carton to form a folded supporting ring then receiving space can be bent.
- folding cartons are used in many applications. In many cases they are part of a packaging unit, which in addition to the folding carton still has a pallet and a lid, the carton is firmly connected to the pallet.
- the outer carton is so kinkable that creates a gap in which the folded support ring is landfilled. With the lid, which closes the folding carton in the use position on the top side, this can be covered in this respect as empties to be designated packaging unit. A large number of such empties packaging can be stacked on top of each other.
- a generic folding carton is from the DE 296 07 050 U1 known. It can be seen that the foldable support ring is formed from a blank, which usually consists of a doubly covered corrugated cardboard and collapsed along introduced buckling or folding lines.
- a corresponding wall thickness must be selected to prevent buckling of the carton and the support ring.
- the invention is therefore based on the object, a folding carton of the generic type so that its production costs are reduced and its usability is improved.
- each corner amplifier consists of a laminated cardboard or paper which is produced as a laminate.
- the individual laminate layers are connected to each other by a melted polyethylene film, whereby the corner amplifier is moisture-resistant and thus suitable for sea transport.
- the L-shaped corner amplifier are attached to the inside of only one of the two legs on one side of the support ring, for example by gluing, staples or the like. It is also conceivable to provide the corner amplifier for connection to the support ring on the corresponding leg with a self-adhesive layer, which allows a particularly simple production of the folding carton.
- two opposite corner amplifier overlap with their exposed legs, wherein the width of these legs is dimensioned so that they do not project beyond the support ring in the folded position.
- corner reinforcement made of laminated laminated cardboard or paper
- a foldable support ring is shown, which is provided overall with the reference numeral 1.
- This support ring 1 has two elongated longitudinal sides 2, which are connected to each other by two opposite end faces, each of which is formed from two end-side halves 5, which are divided over a folding edge 4 foldable.
- each of which is formed in cross-section L-shaped, preferably isosceles and extends over the height of the side walls 2 and the end side halves 5.
- an unfolded longitudinal side 2 associated corner amplifier 3 are connected with their facing legs with this longitudinal side 2, for example by gluing or stapling, while the other, angled legs relative to the associated end half 5 is exposed, that is not connected to this end face half 5, however overlaps in the border area.

Abstract
Description
Die Erfindung betrifft einen Faltkarton mit einem faltbaren Umkarton und einem am Umkarton innenseitig anliegenden, faltbaren Stützring, wobei Seitenwände des Umkartons unter Bildung eines den gefalteten Stützring dann aufnehmenden Zwischenraumes knickbar sind.The invention relates to a folding carton with a foldable outer carton and an inner side of the carton lying, foldable support ring, wherein side walls of the carton to form a folded supporting ring then receiving space can be bent.
Derartige Faltkartons kommen in vielen Einsatzbereichen zur Anwendung. Vielfach sind sie Bestandteil einer Verpackungseinheit, die neben dem Faltkarton noch eine Palette sowie einen Deckel aufweist, wobei der Umkarton mit der Palette fest verbunden ist.Such folding cartons are used in many applications. In many cases they are part of a packaging unit, which in addition to the folding carton still has a pallet and a lid, the carton is firmly connected to the pallet.
Für einen geringstmöglichen Raumbedarf zum Leertransport sind der Umkarton wie auch der Stützring faltbar ausgebildet. Dabei ist der Umkarton so knickbar, das ein Zwischenraum entsteht, in dem der gefaltete Stützring deponierbar ist. Mit dem Deckel, der den Faltkarton in Gebrauchsstellung oberseitig verschließt, ist diese insoweit als Leergut zu bezeichnende Verpackungseinheit abdeckbar. Eine Vielzahl solcher Leergut-Verpackungen sind übereinander stapelbar.For a minimum space requirement for empty transport of the carton as well as the support ring are foldable. The outer carton is so kinkable that creates a gap in which the folded support ring is landfilled. With the lid, which closes the folding carton in the use position on the top side, this can be covered in this respect as empties to be designated packaging unit. A large number of such empties packaging can be stacked on top of each other.
Ein gattungsgemäßer Faltkarton ist aus der
Insbesondere beim Übereinanderstapeln aufgerichteter und befüllter Verpackungseinheiten ergeben sich jedoch Stabilitätsprobleme, da die Last einer aufgesetzten Verpackungseinheit lediglich von den Seitenwänden des Umkartons und denen des Stützringes aufgenommen wird.In particular, when stacking upright and filled packaging units, however, stability problems arise because the load of an attached packaging unit is received only by the side walls of the outer carton and those of the support ring.
Da das im Faltkarton aufgenommene Stückgut durchaus relativ schwer sein kann, muss, um ein Einknicken des Umkartons und des Stützringes zu verhindern, eine entsprechende Wandstärke gewählt werden.Since the cargo received in the folding carton can be quite heavy, a corresponding wall thickness must be selected to prevent buckling of the carton and the support ring.
Jedoch führt dies zu einem hohen Materialeinsatz, der zum einen die Herstellung des Faltkartons verteuert und zum anderen ein verhältnismäßig hohes Gewicht der Verpackung zur Folge hat, was insbesondere beim Transport als Leergut sehr nachteilig ist.However, this leads to a high use of material, which on the one hand increases the cost of producing the folding carton and on the other hand results in a relatively high weight of the packaging, which is very disadvantageous, in particular, during transport as empties.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Faltkarton der gattungsgemäßen Art so weiterzuentwickeln, dass seine Herstellungskosten gesenkt und seine Verwendbarkeit verbessert wird.The invention is therefore based on the object, a folding carton of the generic type so that its production costs are reduced and its usability is improved.
Diese Aufgabe wird durch einen Faltkarton mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a folding carton with the features of
Ein in diesem Sinne ausgebildeter Faltkarton bietet gegenüber dem bekannten eine ganze Reihe von Vorteilen.A trained in this sense folding carton offers over the known a whole series of advantages.
Bemerkenswert ist zunächst einmal die wesentlich höhere Knicksteifigkeit in Gebrauchs-, also in aufgerichteter Stellung, die entweder eine höhere Lastabstützung erlaubt oder eine geringere Dimensionierung der Wandstärken sowohl des Umkartons wie auch des Stützrings. Während bislang ausschließlich die Seitenwände des Umkartons und des Stützringes die vertikal wirkende Druckkraft aufnehmen, erfolgt die Kraftaufnahme des neuen Faltkartons vor allem durch die Eckenverstärker, die nach einer bevorzugten Ausbildung als Winkelprofil gestaltet sind, d.h. etwa L-förmig, wodurch sich eine hohe Knicksteifigkeit ergibt.Noteworthy is first of all the much higher buckling stiffness in use, so in an upright position, which allows either a higher load support or a smaller dimensioning of the wall thickness of both the outer carton as well as the support ring. While so far only the side walls of the outer carton and the support ring absorb the vertical compressive force, takes the power of the new folding carton mainly by the corner stirrers, which are designed according to a preferred embodiment as an angle profile, that is approximately L-shaped, resulting in a high buckling resistance.
Ein weiterer vorteilhafter Gedanke der Erfindung sieht vor, dass jeder Eckenverstärker aus einem Schichtkarton oder -papier besteht, das als Laminat hergestellt ist. Dabei sind die einzelnen Laminatschichten durch eine aufgeschmolzene Polyethylen-Folie miteinander verbunden, wodurch der Eckenverstärker feuchtigkeitsfest ist und somit für einen Hochseetransport geeignet.A further advantageous idea of the invention provides that each corner amplifier consists of a laminated cardboard or paper which is produced as a laminate. The individual laminate layers are connected to each other by a melted polyethylene film, whereby the corner amplifier is moisture-resistant and thus suitable for sea transport.
Ein weiterer Gedanke der Erfindung sieht vor, dass die L-förmigen Eckenverstärker mit der Innenseite lediglich eines der beiden Schenkel an einer Seite des Stützrings befestigt sind, beispielsweise durch Verkleben, Klammern oder dergleichen. Denkbar ist auch, die Eckenverstärker zur Verbindung mit dem Stützring an dem entsprechenden Schenkel mit einer selbsthaftenden Klebschicht zu versehen, was eine besonders einfache Herstellung des Faltkartons erlaubt.Another idea of the invention provides that the L-shaped corner amplifier are attached to the inside of only one of the two legs on one side of the support ring, for example by gluing, staples or the like. It is also conceivable to provide the corner amplifier for connection to the support ring on the corresponding leg with a self-adhesive layer, which allows a particularly simple production of the folding carton.
Durch die Befestigung der Eckenverstärker jeweils lediglich mit einem Schenkel an einer Seite des Stützringes kann dieser problemlos gefaltet werden, wobei sich anbietet, die Eckenverstärker an den Seiten des Stützringes zu befestigen, die nicht für eine Faltung vorgesehen sind.By attaching the corner amplifier each with only one leg on one side of the support ring this can be easily folded, offering to fix the corner amplifier on the sides of the support ring, which are not intended for a folding.
Im gefalteten Zustand des Stützringes überlappen sich zwei gegenüberliegende Eckenverstärker mit ihren freiliegenden Schenkeln, wobei die Breite dieser Schenkel so dimensioniert ist, dass sie den Stützring in gefalteter Stellung nicht überragen.In the folded state of the support ring, two opposite corner amplifier overlap with their exposed legs, wherein the width of these legs is dimensioned so that they do not project beyond the support ring in the folded position.
Anstelle der genannten Ausbildung der Eckenverstärker aus einem laminierten Schichtkarton oder -papier besteht die Möglichkeit, den Eckenverstärker aus mehreren Lagen ein- oder mehrfach gedeckter Wellpappe herzustellen, um so die notwendige Knicksteifigkeit bzw. Druckfestigkeit zu erreichen.Instead of the above-mentioned embodiment of the corner reinforcement made of laminated laminated cardboard or paper, it is possible to produce the corner reinforcement from several layers of single or multiple covered corrugated cardboard in order to achieve the necessary buckling resistance or compressive strength.
Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous embodiments of the invention are characterized in the subclaims.
