Description

Die Erfindung betrifft einen Behälter mit wenigstens einer Wand, die aus Wenigstens einem bogenartigen Segment hergestellt ist, das eine Trägerschicht und eine Schutzschicht enthält und Wenigstens eine Kante aufweist, die von einem Schutzbezug umschlossen ist, der die innere Oberfläche und die äußere Oberfläche Wenigstens des an die Kante angrenzenden Bereichs des Segmentes überdeckt, der eine derart reduzierte Dicke hat, daß das Segment einschließlich des Schutzbezuges eine insgesamt wenigstens annähernd gleichbleibende Dicke hat, wobei die Trägerschicht in dem von dem Schutzbezug zu überdeckenden Bereich verdichtet ist.The invention relates to a container with at least one Wall made from at least one arch-like segment which is a backing layer and a protective layer contains and has at least one edge that of a Protective cover is enclosed, the inner surface and the outer surface of at least that adjacent to the edge Covered area of the segment, which reduced such a Thickness has that segment including the protective cover an overall at least approximately the same Has thickness, with the backing layer in that of the protective cover area to be covered is compressed.

In der DE-A-30 23 835 ist ein Behälter beschrieben, der aus mehreren Wänden zusammengesetzt ist. Jede Wand enthält eine Trägerschicht aus Papier und wenigstens eine die Trägerschicht bedeckende Schutzschicht, die nach dem Zusammenbau zum Inneren des Behälters weist.In DE-A-30 23 835 a container is described which consists of is composed of several walls. Each wall contains one Backing layer made of paper and at least one the backing layer covering protective layer after assembly points to the inside of the container.

Bei der Herstellung des Behälters wird ein Segment derart geformt, daß ein im wesentlichen zylindrischer Korpus entsteht. Hierbei ragt ein Endbereich des Segmentes mit einer Kante in das Innere des Behälters.During the manufacture of the container, a segment is shaped in such a way that an essentially cylindrical body is created. Here, an end region of the segment projects with an edge in the inside of the container.

Die in das Innere des Behälters ragende Kante ist mit einem Schutzbezug umschlossen. Als Schutzbezug dient die Schutzschicht des Segmentes, die im Bereich der Kante um 180° umgebogen ist, so daß die Kante selbst und die sich hieran anschließenden Bereiche des Segmentes von dem Schutzbezug umschlossen sind.The edge protruding into the interior of the container is marked with a Protective cover enclosed. The protective layer serves as a protective cover of the segment that is bent by 180 ° in the area of the edge is so that the edge itself and the adjoining it Areas of the segment enclosed by the protective cover are.

Zum Herstellen und Anbringen des bekannten Schutzbezuges wird zunächst in dem die Kante enthaltenden Endbereich die Trägerschicht des Segmentes abgeschabt, so daß das Segment dort im wesentlichen nur noch die halbe Materialstärke aufweist. Sodann wird eine Längsnut in der Mittellinie des abgeschabten Bereiches ausgebildet und Klebstoff auf den abgeschabten Bereich aufgebracht. Schließlich wird der abgeschabte Bereich entlang der Längsnut um 180° umgebogen und zusammengeklebt. Hierdurch wird im Bereich der Kante ein Schutzbezug hergestellt, der durch die umgebogene Schutzschicht des Segmentes gebildet wird und der die Kante selbst sowie die beiden einander gegenüberliegenden Seiten des Segmentes im Anschluß an die Kante bedeckt.To produce and attach the known protective cover first the carrier layer in the end region containing the edge scraped the segment so that the segment there in essentially only has half the material thickness. Then becomes a longitudinal groove in the center line of the scraped off Area formed and adhesive on the scraped area upset. Eventually the scraped area bent along the longitudinal groove by 180 ° and glued together. This creates a protective cover in the area of the edge, by the bent protective layer of the segment is formed and the edge itself and the two each other opposite sides of the segment following covered the edge.

Durch das Abtragen der Materialstärke bei dem Endstreifen auf die halbe Dicke und das anschließende Zusammenfalten des Endstreifens wird im Bereich der Kante eine Dicke erhalten, die der Dicke des Segmentes Insgesamt Wenigstens annähernd entspricht. Das Segment hat mithin einschließlich des Schutzbezuges eine insgesamt Wenigstens annähernd gleichbleibende Dicke. Mit der Materialabtragung bei dem Endbereich des Segmentes soll bei dem bekannten Behälter erreicht werden, daß beim Umfalten Risse, die bei voller Materialstärke möglicherweise entstehen könnten, vermieden werden.By removing the material thickness on the end strip half the thickness and then folding the end strip together a thickness is obtained in the area of the edge, the the thickness of the segment Overall at least approximately. The segment therefore has a protective cover an overall at least approximately the same Thickness. With the removal of material from the end area of the segment should be achieved in the known container that when folding, cracks that may occur with full material thickness could be avoided.

In der US-A-31 57 337 ist ein Behälter gemäß dem Oberbegriff des Anspruchs 1 beschrieben, dessen Mantel durch spiraliges Wickeln mehrerer Materialbahnen hergestellt wird. Der Mantel enthält mehrere Schutzschichten und eine Trägerschicht, die im Bereich einer Kante durch einen Schutzbezug überdeckt ist. Der von dem Schutzbezug überdeckte Bereich der Trägerschicht ist verdichtet, so daß der Mantel eine insgesamt gleichbleibende Dicke hat. Das Verdichten der Trägerschicht geschieht offenbar während des spiraligen Wickelns, wobei die Schutzschicht und der Schutzbezug nicht verdichtet werden.In US-A-31 57 337 is a container according to the preamble of claim 1 described, whose jacket by spiral winding several Material webs is produced. The coat contains several protective layers and a backing layer in the area an edge is covered by a protective cover. Of the area of the carrier layer covered by the protective cover condensed, so that the coat is a constant overall Has thickness. The carrier layer is apparently compacted during spiral winding, the protective layer and the protective cover is not compressed.

Die EP 0 527 647 A2 schließlich zeigt einen Behälter, bei dem eine wendelförmig verlaufende Naht an den Kanten von wendelförmig aufeinandergewickelten Streifen aus Papier oder Karton gebildet ist, die später ein leichtes Öffnen des zylindrischen Behälters ermöglichen soll. Zu diesem Zweck werden die überlappenden Kanterbereiche vor dem Wickeln leicht verdichtet und mit einem temporär haltenden Klebstoff versehen, der wegen der Materialverdichtung nicht voll in das Material eindringen und daher auch wieder gelöst werden kann.Finally, EP 0 527 647 A2 shows a container in which a helical seam at the edges of helical strips of paper or cardboard wound on one another is formed, which later easy opening of the cylindrical Container should allow. For this purpose the overlapping edge areas slightly compressed before wrapping and provided with a temporary adhesive that do not penetrate fully into the material due to the material compression and therefore can be solved again.

Es ist die Aufgabe der Erfindung, bei dem Behälter der eingangs genannten Art einen Kantenschutz aufzuzeigen, der einfach und kostengünstig bei einem Segment ohne Vergrößerung von dessen Dicke hergestellt werden kann.It is the object of the invention in the container of the beginning to show an edge protection that is simple and inexpensive for a segment without enlarging whose thickness can be made.

Die Aufgabe wird dadurch gelöst, daß auch die Schutzschicht des Segmentes in dem von dem Schutzbezug zu überdeckenden Bereich verdichtet ist. The object is achieved in that the protective layer of the segment in the area to be covered by the protective cover is compressed.

Die erfinderische Bauweise führt zu dem Vorteil, daß die Reduzierung der Dicke des Segmentes in dem von dem Schutzbezug zu überdeckenden Bereich in besonders einfacher und kostengünstiger Weise vonstatten gehen kann. Nach dem Aufbringen des Schutzbezuges auf den in der Dicke reduzierten Bereich hat das Segment, das für die Herstellung des Behälters verwendet wird, eine insgesamt wenigstens annähernd gleichbleibende Dicke.The inventive design leads to the advantage that the reduction the thickness of the segment in that of the protective cover too covering area in a particularly simple and cost-effective manner Way can take place. After applying the protective cover the segment has a reduced thickness, used for the manufacture of the container, a overall at least approximately constant thickness.

Die gleichbleibende Dicke ermöglicht eine vereinfachte Herstellung des Behälters. Segmente von gleichbleibender Dicke können besonders gut in Stapeln einer Maschine zum Herstellen von Behältern vorgelegt werden. Es ist außerdem möglich, eine Vielzahl von Segmenten zu einem Kartonband zusammenzufassen, das in aufgerollter Form einer Maschine zum Herstellen von Behältern vorgelegt werden kann.The constant thickness enables simplified production of the container. Segments of constant thickness can be particularly good in stacks of a machine for manufacturing Containers are presented. It is also possible to have a variety of segments into a cardboard tape, which in rolled-up form of a machine for manufacturing containers can be presented.

Die Erfindung kann sinnvoll eingesetzt werden bei allen Behältern, bei denen verhindert werden soll, daß ein Medium, insbesondere das Füllgut, in die Wand des Behälters eindringt. Im Bereich der Kante ist die Oberfläche des Segmentes, das zu einer Wand des Behälters weiterverarbeitet werden soll, häufig aufgebrochen, insbesondere dann, wenn die Kante durch Schneiden oder Stanzen hergestellt ist. Durch das Anbringen des Schutzbezuges kann im Bereich der Kanten ein gleichartiger oder ähnlicher Schutz hergestellt werden, wie er auch in den anderen Bereichen des Behälters besteht. Auf die äußere Gestalt des Behälters kommt es nicht an. The invention can be usefully used in all containers, in which a medium is to be prevented, in particular the filling material penetrates into the wall of the container. in the The area of the edge is the surface of the segment leading to a Wall of the container to be processed, often broken open, especially if the edge is cut or Stamping is made. By attaching the protective cover can be similar or similar in the area of the edges Protection can be established as it is in other areas of the container. Comes on the outer shape of the container not at it.

In vorteilhafter Ausgestaltung kann der Schutzbezug selbst bei den zu überdeckenden Bereich des Segmentes verdichtet werden.In an advantageous embodiment, the protective cover compacted even in the area of the segment to be covered become.

Die Erfindung kann zur Anwendung kommen bei allen Kanten, die bei einen Behälter mit einem Schutzbezug abgedeckt sein sollen.The invention can be applied to all edges which a container should be covered with a protective cover.

So kann die abzudeckende Kante auch bei einer Öffnung vorhanden sein, die in eine Wand des Behälters eingebracht ist.So the one to be covered Edge also be present at an opening that is in a wall of the container is introduced.

Diese Öffnung kann vorteilhaft durch eine Aufreißlasche abgedeckt werden, wobei der durch die Aufreißlasche abdeckbare Bereich des Segmentes ebenfalls eine reduzierte Dicke hat. Das Segment ist dann sowohl in den von dem Schutzbezug abgedeckten Bereich der Öffnung als auch in den durch die Aufreißlasche abgedeckten Bereich in wesentlichen gleichbleibend dick.This opening can advantageously be covered by a pull tab be, the area covered by the tear tab of the Segment also has a reduced thickness. The segment is then both in the area covered by the protective cover Opening as well as in those covered by the pull tab Area of essentially constant thickness.

Das Verdichten des Segmentes kann vorteilhaft dadurch geschehen, daß mechanischer Druck in dem zu verdichtenden Bereich ausgeübt wird.The segment can advantageously be compacted by that mechanical pressure is exerted in the area to be compressed becomes.

  • Der in Figuren 1 und 3 dargestellte Behälter 1 ist als Dose ausgebildet. Er setzt sich aus einem zylindrischen Mantel 2, einen kreisförmigen Boden 4 und einem kreisförmigen Deckel 3 zusammen.The container 1 shown in Figures 1 and 3 is a can educated. It consists of a cylindrical jacket 2, a circular bottom 4 and a circular cover 3 together.

    Der Deckel 3 ist mit einer Öffnung 7 versehen, die mit einer Aufreißlasche 8 verschlossen werden kann. Die Aufreißlasche 8 ist in Figur 3 in einer von der Öffnung 7 weggeklappten Position dargestellt. Die Wand 5 des Deckels 3, die Wand des Bodens 4 und die Wand 6 des Mantels 2 sind unlosbar miteinander verbunden und bilden zusammen eine einheitliche Wand des Behälters 1. The lid 3 is provided with an opening 7, which with a Pull tab 8 can be closed. The tear tab 8 is in Figure 3 in a position folded away from the opening 7 shown. The wall 5 of the lid 3, the wall of the bottom 4 and the wall 6 of the jacket 2 are inextricably linked and together form a uniform wall of the container 1.

    Wie insbesondere aus Figur 2 ersichtlich ist, wird der Mantel 2 des Behälters 1 durch eine im Querschnitt im wesentlichen kreisringförmig verlaufende Wand 6 gebildet. Die Wand 6 wird aus einem bogenartigen Segment 6' (vgl. Figur 5) hergestellt.As can be seen in particular from FIG. 2, the jacket 2 of the container 1 by an essentially circular in cross section extending wall 6 formed. The wall 6 becomes one arcuate segment 6 '(see FIG. 5).

    Um die in Figur 2 dargestellte, im Querschnitt kreisringförmige Gestalt der Wand 6 zu erhalten, wird das rechteckige, bogenartige Segment 6' über einen nicht gezeigten, zylindrischen Dorn aufgerollt. Hierbei überlappen die Endbereiche 15', 56' des Segmentes 6' einander, so daß bei der Wand 6 zwei einander überlappende Abschnitte 15, 56 gebildet werden. Hierbei kommt die Kante 13 des überlappenden Abschnitts 15 innerhalb des Mantels 2 und die Kante 14 des überlappenden Abschnitts 56 außerhalb des Mantels 2 zu liegen. Die überlappenden Abschnitte 15 und 56 der Endbereiche des zu der Wand 6 verformten Segmentes 6' werden gegeneinander angelegt und, vorzugsweise durch Heißsiegeln, bei der Siegelstelle 26 miteinander verbunden. Die Wand 6 hat nun die Gestalt einer Hülse, sie verläuft also, wie aus Figur 2 ersichtlich ist, im Querschnitt kreisringförmig. Diese kreisringförmige Gestalt wird sich im Verlaufe des weiteren Fertigungsverfahrens nicht mehr ändern. In der Seitenansicht ist die nun erreichte Fertigungsstufe der hülsenförmigen Wand 6 in Figur 15 gezeigt.Around the circular cross-section shown in Figure 2 To get the shape of the wall 6, the rectangular, arch-like Segment 6 'rolled up over a cylindrical mandrel, not shown. Here, the end regions 15 ', 56' of the segment overlap 6 'each other, so that two overlapping one another at wall 6 Sections 15, 56 are formed. Here comes the edge 13 of the overlapping section 15 within the shell 2 and the Edge 14 of the overlapping section 56 outside the casing 2 to lie. The overlapping sections 15 and 56 of the end regions of the segment 6 'deformed into the wall 6 are against one another applied and, preferably by heat sealing, at the sealing point 26 connected to each other. The wall 6 now has the shape a sleeve, so it runs, as can be seen from Figure 2, circular in cross-section. This circular shape will not change in the course of the further manufacturing process change more. In the side view is the production stage now reached the sleeve-shaped wall 6 shown in Figure 15.

    Wie aus Figur 5 ersichtlich ist, sind bei dem nicht verformten Segment 6' Randbereiche 16', 17' vorhanden, die entlang Biegekanten 20', 21' umgebogen werden können. Bei der in in Figur 15 dargestellten Fertigungsstufe der Wand 6 bilden die Randbereiche 16, 17 die beiden Stirnenden der hülsenförmigen Wand 6. Das Umbiegen der Randbereiche 16, 17 wird in einem späteren, weiter unten noch beschriebenen Arbeitsgang durchgeführt.As can be seen from Figure 5, the are not deformed Segment 6 'edge regions 16', 17 'are present, along the bending edges 20 ', 21' can be bent. In the case in FIG. 15 Manufacturing stage of the wall 6 shown form the edge areas 16, 17 the two ends of the sleeve-shaped wall 6. Das Bending over the edge regions 16, 17 will continue in a later the procedure described below.

    Der Deckel 3 und der Boden 4 werden jeweils aus einem bogenartigen Segment hergestellt, wobei nur das Segment 5' für den Deckel 3 in Figuren 10, 11 und 12 zeichnerisch dargestellt ist. Die kreisförmigen, bogenartigen Segmente 5' werden entlang der Biegekante 57 derart verformt, daß bei dem Deckel 3 ein abragender Rand 18 (vgl. auch Figur 4) und bei dem Boden 4 ein abragender Rand 19 gebildet wird.The lid 3 and the bottom 4 are each made of an arc Segment produced, with only the segment 5 'for the Cover 3 in Figures 10, 11 and 12 is shown in the drawing. The circular, arcuate segments 5 'are along the Bending edge 57 deformed such that a protruding at the cover 3 Edge 18 (see also FIG. 4) and a protruding one at the bottom 4 Edge 19 is formed.

    Zum Zusammenfügen des Behälters 1 werden der Boden 4 und der Deckel 3 in das Innere der in Figur 15 dargestellten, hülsenformigen Wand 6 eingebracht, so daß die abragenden Ränder 18, 19 jeweils nach außen weisen. Sodann werden der Randbereich 16 des Mantels 2 um die Biegekante 20 über den abragenden Rand 18 des Deckels 3 und der Randbereich 17 des Mantels 2 um die Biegekante 21 über den abragenden Rand 19 des Bodens 4 umgebogen, so daß die in Figuren 1 und 3 dargestellte Gestalt des Behälters 1 erhalten wird.To assemble the container 1, the bottom 4 and the Cover 3 into the interior of the sleeve-shaped shown in Figure 15 Wall 6 introduced so that the projecting edges 18, 19th each point outwards. Then the edge region 16 of the Jacket 2 around the bending edge 20 over the protruding edge 18 of the Cover 3 and the edge region 17 of the casing 2 around the bending edge 21 bent over the projecting edge 19 of the bottom 4, so that the 1 and 3 shown shape of the container 1 obtained becomes.

    In den vorbeschriebenen stirnendigen Bereichen, in denen die Randbereiche 16 und 17 des Mantels 2 umgebogen sind, werden der Deckel 3 und der Boden 4 durch Verpressen und Heißsiegeln miteinander verbunden. Durch das beschriebene feste Verbinden in den stirnseitigen Bereichen des Behälters 1 sind die dort verlaufenden Kanten, die bei dem Segment 5' für den Deckel 3, dem Segment für den Boden 4 und dem Segment 6' für den Mantel 2 noch frei gelegen haben, gut geschützt, so daß es eines zusätzlichen Kantenschutzes dort nicht bedarf.In the frontal areas described above, in which the Edge areas 16 and 17 of the jacket 2 are bent over Lid 3 and the bottom 4 by pressing and heat sealing together connected. Through the described fixed connection in the frontal areas of the container 1 are those running there Edges in the segment 5 'for the lid 3, the segment for the bottom 4 and the segment 6 'for the jacket 2 still free have been well protected, making it an additional one Edge protection is not required there.

    Bei der in das Innere des Mantels 2 ragenden Kante 13 (vgl. Figur 2) ist ein Kantenschutz vorgesehen, der nachstehend anhand von Figuren 6 und 8 beschrieben wird. Für die Herstellung der in Figur 6 dargestellten, im Querschnitt kreisringförmigen Wand 6 wird das in Figur 8 dargestellte Segment 6' verwendet. Das Segment 6' der Figur 8 ist vor der Verformung mit einer ersten Ausführungsform eines Schutzbezuges 24 versehen, der auch bei der geformten Wand 6 der Figur 6 dargestellt ist.With the edge 13 protruding into the interior of the casing 2 (see FIG 2) edge protection is provided, which is described below using Figures 6 and 8 is described. For the manufacture of the FIG. 6 shows wall 6 which is circular in cross section segment 6 'shown in FIG. 8 is used. The Segment 6 'of FIG. 8 is before being deformed with a first one Embodiment of a protective cover 24 provided, which also in the shaped wall 6 of Figure 6 is shown.

    Aus Figuren 6 und 8 ist ersichtlich, daß die Wand 6 des Mantels 2 aus einer Trägerschicht 22, vorzugsweise aus Papier oder Karton, und aus einer Schutzschicht 23 besteht. Sowohl die Trägerschicht 22 als auch die Schutzschicht 23 können aus mehreren Materiallagen bestehen. Die Schutzschicht 23, die die innere Oberfläche 12 der Wand 6 bildet, dient dem Schutz des Füllgutes und kann beispielsweise auch eine Lage aus Aluminium enthalten. Bei der äußeren Oberfläche 11 ist bei der hier dargestellten Ausführungsform eine zusätzliche Schutzschicht nicht vorgesehen. Es ist selbstverständlich bei anderen Ausführungen denkbar, eine solche Schutzschicht, beispielsweise zum Schutz des Behälters 1 oder des Füllgutes vor äußeren Einwirkungen, bei der äußeren Oberfläche 11 der Wand 6 anzubringen.It can be seen from FIGS. 6 and 8 that the wall 6 of the casing 2 a carrier layer 22, preferably paper or cardboard, and consists of a protective layer 23. Both the backing layer 22 and the protective layer 23 can consist of several layers of material consist. The protective layer 23 covering the inner surface 12 the wall 6 forms, serves to protect the contents and can for example also contain an aluminum layer. In the outer surface 11 is in the embodiment shown here an additional protective layer is not provided. It is of course conceivable with other versions, such Protective layer, for example to protect the container 1 or Contents before external influences, on the outer surface 11 to attach the wall 6.

    Die in das Innere des Mantels 2 ragende Kante 13 der Wand 6 ist mit dem vorerwähnten Schutzbezug 24 versehen, der auch die innere Oberfläche 12 und die äußere Oberfläche 11 des zu der Wand 6 verformten Segmentes 6' in dem Bereich 27 überdeckt. Das Segment 6' hat in dem von dem Schutzbezug 24 überdeckten Bereich 27 eine derart reduzierte Dicke, daß die Gesamtdicke einschließlich des Schutzbezuges 24 des Segmentes 6' wenigstens annähernd gleich groß ist wie die Dicke des Segmentes 6' in den übrigen Bereichen.The edge 13 of the wall 6 protruding into the interior of the jacket 2 provided with the aforementioned protective cover 24, which also the inner Surface 12 and the outer surface 11 of the deformed to the wall 6 Segment 6 'covered in the area 27. The segment 6 ' has an area 27 covered by the protective cover 24 such reduced thickness that the total thickness including the Protective cover 24 of the segment 6 'at least approximately the same is as large as the thickness of the segment 6 'in the remaining areas.

    Bei der in Figur 9 dargestellten Ausführungsform wird der Schutzbezug 39 ebenso wie bei der in Figuren 6 und 8 dargestellten Ausführungsform, durch ein separates Bauteil gebildet, das die Gestalt eines schmalen Streifens hat. Der Schutzbezug 39 ist, wie dies in Figur 9 dargestellt ist, zusätzlich verdichtet.In the embodiment shown in Figure 9 the protective cover 39 as well as that in FIGS. 6 and 8 illustrated embodiment, by a separate component formed, which has the shape of a narrow strip. Of the Protective cover 39 is as shown in FIG. 9 is shown, additionally compressed.

    Bei der in Figur 8 dargestellten Ausführungsform hat das Segment 6' in dem die Kante 13 enthaltenden Bereich 27 eine reduzierte Dicke. Hierbei entspricht die Dicke des Bereichs 27 der Ausführungsform der Figur 8 der Dicke des Bereichs 27 der Figur 6. Der Schutzbezug 24 weist, ebenso wie bei Figur 6, eine gleichbleibende Dicke auf. Allerdings hat außer dem Bereich 34 der Trägerschicht 22 auch der Bereich 35 der Schutzschicht 23 eine reduzierte Dicke.In the embodiment shown in FIG. 8, the segment 6 ' in the region 27 containing the edge 13 a reduced one Thickness. Here, the thickness of the region 27 corresponds to the embodiment 8 shows the thickness of region 27 of FIG. 6. As in FIG. 6, the protective cover 24 has a constant thickness. In addition to the area 34 of the carrier layer 22, however, the Area 35 of the protective layer 23 has a reduced thickness.

    Bei der in Figur 9 dargestellten Ausführungsform hat das Segment 42 in dem die Kante 13 enthaltenden Bereich 43 eine reduzierte Dicke. Hier sind der Bereich 44 der Trägerschicht 22, der Bereich 35 der Schutzschicht 23 und die an den Oberflächen 11 und 12 anliegenden Bereiche 40 und 41 des Schutzbezuges 39 in der Dicke reduziert. Die Reduzierung ist derart, daß das Segment 42 eine insgesamt gleichbleibende Dicke hat.In the embodiment shown in Figure 9, the segment 42 in the area 43 containing the edge 13 a reduced one Thickness. Here, the area 44 of the carrier layer 22 is the area 35 of the protective layer 23 and that on the surfaces 11 and 12 adjacent areas 40 and 41 of the protective cover 39 in thickness reduced. The reduction is such that segment 42 is a overall constant thickness.

    Bei der in Figur 7 dargestellten Ausbildung ist die Kante 13 durch eine zweite Ausführungsform eines Schutzbezuges 25 überdeckt. Dieser Schutzbezug 25 ist einstückig mit der Schutzschicht, die die innere Oberfläche 12 der Wand 6 bildet, hergestellt. Ein zusätzlicher Schutzbezug ist also nicht vorhanden. Der Bereich 28 des die Wand 6 bildenden Segmentes 55 ist in der Dicke reduziert, so daß ein Segment 55 mit insgesamt gleichbleibender Dicke erhalten wird. Die reduzierte Dicke des Bereichs 28 des Segmentes 55 wird durch Verdichten des Bereichs 28 der Trägerschicht 22 erhalten, deren Dicke hierdurch verringert wird.In the embodiment shown in FIG Edge 13 through a second embodiment of a protective cover 25 covered. This protective cover 25 is in one piece with the protective layer, which forms the inner surface 12 of the wall 6. There is therefore no additional protective cover. The area 28 of the segment 55 forming the wall 6 is in FIG Thickness reduced so that a segment 55 with a constant overall Thickness is obtained. The reduced thickness of area 28 of the segment 55 is made by densifying the region 28 of the carrier layer 22 obtained, the thickness of which is reduced.

    Der Schutzbezug 24; 25; 39 ist in allen Ausführungsformen bei den Segmenten 6'; 42; 55 bereits vorhanden, bevor diese zu der Wand 6 des Mantels 2 verformt werden.The protective cover 24; 25; 39 is in all embodiments in the Segments 6 '; 42; 55 already existed before this to the Wall 6 of the jacket 2 are deformed.

    In Figuren 11 und 12 ist der Kantenschutz bei der Öffnung 7 des Segmentes 5' für die Wand 5 des Deckels 3 dargestellt. Der Kantenschutz besteht aus einem Schutzbezug 45, der eine Kante 49 überdeckt, die entlang dem Rand der in das Segment 5' eingebrachten Öffnung verläuft. In dem von dem Schutzbezug 45 überdeckten Bereich 46 ist die Dicke reduziert.In Figures 11 and 12, the edge protection at the opening 7 of the Segment 5 'shown for the wall 5 of the lid 3. Of the Edge protection consists of a protective cover 45 which has an edge 49 covers that along the edge of the introduced into the segment 5 ' Opening runs. In the one covered by the protective cover 45 Area 46 is reduced in thickness.

    Die mit dem Schutzbezug 45 versehene Öffnung 7 ist, wie oben bereits erwähnt wurde, durch eine Aufreißlasche 8 verschließbar. Die Aufreißlasche 8 ist mit einem anliegenden Teil 47 an der äußeren Oberfläche 9 des Segmentes 5', vorzugsweise durch Heißsiegeln, befestigt. In den Bereich 50, in dem das Segment 5' durch das anliegende Teil 47 der Aufreißlasche 8 überdeckt wird, ist das Segment 5' weniger dick.The opening 7 provided with the protective cover 45 is as above already mentioned, can be closed by a pull tab 8. The tear tab 8 is with an adjacent part 47 on the outer surface 9 of segment 5 ', preferably by heat sealing, attached. In the area 50 in which the segment 5 ' is covered by the adjacent part 47 of the pull tab 8, the segment is 5 'less thick.

    Die Aufreißlasche 8 besitzt ein verschwenkbares Teil 48, das in Figur 11 in einer von der Öffnung 7 weggeklappten Position 48' und in Figur 12 in einer die Öffnung 7 verschließenden Position gezeigt ist. In dem Bereich, in den das verschwenkbare Teil 48 nach dem Verschließen an das Segment 5' zur Anlage kommt, besitzt dieses einen Bereich 51 mit reduzierter Dicke. Häufig genügt es aber, die reduzierte Dicke nur dort vorzusehen, wo sich der Schutzbezug 45 befindet.The tear tab 8 has a pivotable part 48 which in FIG. 11 in a position 48 ′ folded away from the opening 7 and in Figure 12 in a position closing the opening 7 is shown. In the area in which the pivotable part 48 comes into contact with the segment 5 'after sealing this one area 51 with reduced thickness. It is often enough but to provide the reduced thickness only where the Protective cover 45 is located.

    In den Bereichen 46, 50 und 51 ist die Dicke des Segmentes 5' derart reduziert, daß dieses auch nach dem Anbringen des Schutzbezuges 45 und der Aufreißlasche 8, auch nach deren Verschließen, eine insgesamt gleichbleibende Dicke hat.In the areas 46, 50 and 51, the thickness of the segment 5 ' reduced in such a way that this also after the protective cover has been applied 45 and the tear tab 8, even after they have been closed, has an overall constant thickness.

    Nach dem Verschwenken der Aufreißlasche 8 in die in Figur 12 dargestellte Position wird die innere Oberfläche des aufklappbaren Teils 48 gegen den Schutzbezug 45, vorzugsweise durch Heißsiegeln, angeheftet, so daß ein dichtender Verschluß hergestellt wird.After the pull tab 8 has been pivoted into the position shown in FIG Position shown is the inner surface of the hinged Part 48 against the protective cover 45, preferably by heat sealing, pinned so that a sealing closure is made becomes.

    Das Segment 5' ist bereits vor dem Verformen zu dem in Figur 4 dargestellten Deckel 3 somit vor dem Zusammenfügen zu dem Behälter 1 in der vorbeschriebenen Weise ausgebildet. Allerdings ist die Aufreißlasche 8 nur dann bereits bei dem Segment 5', also vor dem Zusammenfügen des Behälters 1, dicht verschlossen, wenn die Öffnung 7 nicht zum Befüllen des Behälters 1 dienen soll.The segment 5 'is already prior to the deformation to that in FIG. 4 illustrated lid 3 thus before assembly to the container 1 trained in the manner described above. However the tear tab 8 only then in the segment 5 ', that is, before the assembly of the container 1, tightly closed when the Opening 7 should not serve to fill the container 1.

    Bei der hier dargestellten Ausführungsform soll der Behälter 1 erst nach dem Befestigen des Deckels 3 an dem Mantel 2 befüllt werden. Das Befüllen erfolgt durch die Öffnung 7, die als Befüllöffnung dient. Zum Befüllen des Behälters 1 wird dafür gesorgt, daß das aufklappbare Teil 48 der Aufreißlasche 8 die Öffnung 7 nicht bedeckt. Das Verschließen der Öffnung 7 durch die Aufreißlasche 8 erfolgt hier also nach dem Füllen des Behälters 1.In the embodiment shown here, the container 1 filled only after attaching the lid 3 to the jacket 2 become. The filling takes place through the opening 7, which as Filling opening serves. For filling the container 1 is for this ensured that the hinged part 48 of the pull tab 8 the Opening 7 not covered. Closing the opening 7 through the Tear flap 8 takes place here after the container has been filled 1.

    Die Aufreißlasche 8 kann zum Entleeren des Behälters 1 aufgerissen werden. Die Öffnung 7 dient so zugleich als Entleeröffnung.The tear tab 8 can be torn for emptying the container 1 become. The opening 7 thus also serves as an emptying opening.

    Durch die insgesamt gleichbleibende Dicke der Segmente 6' für den Mantel 2, der Segmente 5' für die Deckel 3 und der Segmente für die Böden 4 ist es möglich, Segmente 6', 6'' und 5', 5'' in Form von Stapeln oder in Form von Kartonbändern 52 und 53 (vgl. Figuren 13 und 14) vorzulegen.Due to the overall constant thickness of the segments 6 'for the Sheath 2, the segments 5 'for the cover 3 and the segments for the bottoms 4 it is possible to form segments 6 ', 6' 'and 5', 5 '' of stacks or in the form of cardboard tapes 52 and 53 (cf. figures 13 and 14).

    Wie aus Figur 13 ersichtlich ist, sind mehrere rechteckige Segmente 6'' zu einem Kartonband 52 zusammengefaßt. Die Segmente 6'' können an den strichpunktierten Linien von den Kartonband 52 abgetrennt werden und bilden dann jeweils ein abgetrenntes, rechteckiges Segment 6' (vgl. Figur 5). Bei der einen Längskante des Kartonbandes 52 ist ein Bezugband 54 angeordnet, das aus einer Vielzahl von nicht abgetrennten Schutzbezügen 24'' zusammgesetzt ist. Bein Abtrennen der Segmente 6'' von dem Kartonband 52 wird ein Teilstück des Bezugbandes 54 mit abgetrennt, wobei dieses abgetrennte Teilstück den Schutzbezug 24' des abgetrennten Segmentes 6' bildet. Das Kartonband 52 hat, auch im Bereich des Bezugbandes 54, eine insgesamt gleichbleibende Dicke. Deshalb kann das Kartonband 52 ohne weiteres als Rolle einer Maschine zum Herstellen von Behältern 1 vorgelegt werden. Der Kantenschutz für den späteren Mantel 2 ist in Gestalt des Bezugbandes 54 bereits bei dem Kartonband 52 vorhanden, so daß bei der Maschine zum erstellen von Behältern 1 Arbeitsgänge zum Anbringen eines Kantenschutzes nicht anfallen.As can be seen from Figure 13, there are several rectangular Segments 6 '' combined into a cardboard tape 52. The segments 6 '' can be seen on the dash-dotted lines from the cardboard tape 52 are separated and then each form a separated, rectangular segment 6 '(see FIG. 5). With one long edge of the cardboard tape 52, a reference tape 54 is arranged which a variety of non-separated protective covers 24 '' is composed. When separating the segments 6 '' from the Cardboard tape 52, a section of the reference tape 54 is also cut off, this separated section having the protective cover 24 ' of the separated segment 6 '. The cardboard tape 52 has, too in the area of the reference band 54, an overall constant Thickness. Therefore, the cardboard tape 52 can easily be used as a roll be presented to a machine for producing containers 1. The edge protection for the later coat 2 is in the form of Reference tape 54 already present in the cardboard tape 52, so that on the machine for creating containers 1 operations for Do not apply edge protection.

    In Figur 14 ist ein Kartonband 53 dargestellt, das eine Vielzahl von Segmenten 5'' für die Deckel 3 enthält. Jedes Segment 5'' ist bereits mit einer Öffnung 7 versehen, wobei die Kante 49 mit einem Schutzbezug 45 abgedeckt ist. An jedem Segment 5'' ist eine Aufreißlasche 8 befestigt, die die in Figur 12 dargestellte verschlossene Position einnimmt. Allerdings ist die Aufreißlasche 8 nicht fest mit dem Schutzbezug 45 verbunden, so daß sie zum Befüllen von der Öffnung 7 weggeklappt werden kann. Das Kartonband 53 mit den Segmenten 5'' hat, auch in Bereich der Schutzbezüge 45 und der Aufreißlaschen 8, eine insgesamt gleichbleibende Dicke. Deshalb ist es möglich, das Kartonband 53 in Form einer Rolle einer Maschine zum Herstellen von Behältern 1 vorzulegen. In Figure 14, a cardboard tape 53 is shown, which is a variety of segments 5 '' for the cover 3 contains. Each segment is 5 '' already provided with an opening 7, the edge 49 with a protective cover 45 is covered. There is 5 '' on each segment attached a tear tab 8, which is shown in Figure 12 takes a closed position. However, the pull tab is 8 not firmly connected to the protective cover 45, so that they are Filling can be folded away from the opening 7. The cardboard tape 53 with segments 5 '', also in the area of protective covers 45 and the tear tabs 8, an overall constant Thickness. Therefore, it is possible to the cardboard tape 53 in the form of a Submit role of a machine for producing containers 1.

    Auch hier fallen Arbeitsgänge zum Anbringen eines Kantenschutzes bei der Maschine zum Herstellen von Behältern 1 nicht an.Here, too, work steps for attaching an edge protection fall not on the machine for producing containers 1.

    Die Reduzierung der Dicke geschieht beispielsweise durch mechanisches Verpressen mit einem geeigneten Werkzeug. Es ist hierbei möglich, das verdichten der von dem Schutzbezug 24; 25; 39; 45 abzudeckenden Bereiche 27; 28; 43; 46 vor, bei oder nach dem Anbringen des Schutzbezuges 24; 25; 39; 45 durchzuführen. Entsprechendes gilt für die von der Aufreißlasche 8 abzudeckenden Bereiche 50, 51. Diese Bereiche 50, 51 können selbstverständlich ebenfalls vor, bei oder nach dem Anbringen der Aufreißlasche 8 verdichtet werden.The thickness is reduced, for example, by mechanical means Press with a suitable tool. It is here possible to compress the of the protective cover 24; 25; 39; 45 areas to be covered 27; 28; 43; 46 before, at or after the attachment of the protective cover 24; 25; 39; 45 to perform. The same applies to those to be covered by the tear tab 8 Areas 50, 51. These areas 50, 51 can of course also before, during or after attaching the pull tab 8 be compressed.

    Für den Schutzbezug 24; 25; 39; 45 wird vorzugsweise heißsiegelfähiges Material, beispielsweise Polyäthylen, verwandt. Dieses Material ermöglicht es, den Schutzbezug 24; 25; 39; 45 mit dem Segment 5'; 6', 42; 55 zu verbinden. Außerdem wird es möglich, bei der Herstellung des Mantels 2 die überlappenden Abschnitte 15, 56 miteinander zu verbinden und beim Anbringen bzw. Verschließen der Aufreißlasche 8 das anliegende Teil 47 mit der äußeren Oberfläche 9 des Segmentes 5' bzw. das verschwenkbare Teil 48 mit dem Schutzbezug 45 zu verbinden.For the protective cover 24; 25; 39; 45 is preferably heat sealable Material, for example polyethylene, related. This Material enables the protective cover 24; 25; 39; 45 with the Segment 5 '; 6 ', 42; 55 to connect. Besides, it will possible in the manufacture of the jacket 2 the overlapping Sections 15, 56 to connect with each other and when attaching or closing the tear tab 8 with the part 47 the outer surface 9 of the segment 5 'or the pivotable To connect part 48 with the protective cover 45.
