Abstract

For separate waste disposal of the inside layer (9), consisting of an aluminium foil, of a packaging container produced by the winding method, the overlapping foil edges (16, 17) are glued together only at a distance from an outside edge (18) of the foil. The non-glued overlapping foil edge (21) allows the inside layer (9) to be peeled off from the cardboard body after the bottom membrane of the packaging container has been removed. The peeling-off movement begins when the bottom membrane is removed due to the fact that its edge is glued to the non-glued overlapping foil edge. A gripping tab is provided on the bottom membrane for removal of the latter. <IMAGE>

Description

Die Erfindung betrifft einen Verpackungsbehälter mit einem Behälterrumpf, der an seinem einen Ende durch eine Bodenmembran und an seinem anderen Ende durch eine Verschlussmembran verschlossen ist, wobei der Behälterrumpf eine Innenschicht aus einem Material aufweist, das andersartig ist als das seiner Aussenschicht und das gleichartig ist mit dem Material der Bodenmembran und wobei diese Innenschicht sich schraubenlinienförmig mit sich überlappenden Rändern am Behälterrumpf erstreckt.The invention relates to a packaging container with a container body which is closed at one end by a bottom membrane and at the other end by a sealing membrane, the container body having an inner layer made of a material which is different from that of its outer layer and which is similar to the material of the bottom membrane and this inner layer extends helically with overlapping edges on the container body.

Ein Behälter dieser Art ist beispielsweise bekannt durch die CH-A-666 458 (US-A-4,632,298). Sein Rumpf wird im Wickelverfahren hergestellt, indem bandförmiges Material für die Schichten schraubenförmig auf einen Dorn zu einem Rohr gewickelt wird, wie es beispielsweise in der GB-B-947,454 beschrieben ist.A container of this type is known, for example, from CH-A-666 458 (US-A-4,632,298). Its fuselage is made in the winding process by winding tape-like material for the layers helically on a mandrel to form a tube, as described, for example, in GB-B-947,454.

Der Erfindung liegt die Aufgabe zugrunde, einen Verpakkungsbehälter der genannten Art zu finden, dessen aus andersartigem Material, beispielsweise Aluminium, bestehende Innenschicht sich für eine von der äusseren Schicht des Behälterrumpfes getrennte Abfallentsorgung auf einfache Weise ablösen lässt. Die Lösung dieser Aufgabe erfolgt erfindungsgemäss dadurch, dass der Rand der Bodenmembran mit dem Folienband der Innenschicht verbunden ist und die sich überlappenden Ränder dieses Folienbandes zumindest in einem äusseren Randbereich verbindungslos übereinander liegen, wobei sich an der Bodenmembran ein Griff befindet, so dass beim Herausreissen der Bodenmembran das Folienband der Innenschicht, beginnend mit einem verbindungslos an dem darunterliegenden Schichtrand anliegenden Bereich des Ueberlappungsrandes, sich von der Aussenschicht ablöst und für eine getrennte Abfallentsorgung mit herausgerissen wird.The invention has for its object to find a packaging container of the type mentioned, the inner layer consisting of a different type of material, for example aluminum, can be easily removed for a waste disposal separate from the outer layer of the container body. This object is achieved according to the invention in that the edge of the bottom membrane is connected to the film strip of the inner layer and the overlapping edges of this film band lie without connection at least in an outer edge area, with a handle being on the bottom membrane, so that when pulling out the Bottom membrane the foil tape of the inner layer, beginning with a connectionless area of the overlap edge on the underlying layer edge, detaching from the outer layer and being torn out for separate waste disposal.

Das Herausreissen der Innenschicht erfolgt besonders einfach, indem die Bodenmembran an dem Ende des Behälterrumpfes vorgesehen ist, an dem der zum Innenraum hin überlappende Rand des Folienbandes spitzwinklig ausläuft, wobei der Rand der Bodenmembran zumindest mit dem spitz auslaufenden, zum Innenraum hin überlappenden Ende des Folienbandes der Innenschicht verbunden ist. Weitere vorteilhafte Ausführungsformen des patentgemässen Verpackungsbehälters sind Gegenstand der abhängigen Patentansprüche und werden im folgenden anhand der Zeichnungen erläutert. Diese haben unterschiedliche Massstäbe und die Dicke der Materialschichten ist nicht proportional, insbesondere nicht zur Grösse des Behälters dargestellt. Es zeigt:

The tearing out of the inner layer is particularly simple in that the bottom membrane is provided at the end of the container body at which the edge of the foil strip overlapping towards the interior ends at an acute angle, the edge of the bottom membrane at least with the pointed end of the foil strip overlapping towards the interior the inner layer is connected. Further advantageous embodiments of the patented packaging container are the subject of the dependent claims and are explained below with reference to the drawings. These have different scales and the thickness of the material layers is not proportional, in particular not shown to the size of the container. It shows:

Der Verpackungsbehälter hat beispielsweise entsprechend den dargestellten Ausführungsbeispielen einen kreiszylindrischen Behälterrumpf 2, der durch Abschneiden aus einem gewickelten Rohrkörper hergestellt worden ist. Eine Bodenmembran 3 verschliesst sein eines Ende 4 und eine Deckelmembran 5 verschliesst sein anderes Ende 6. Beide Membranen 3,5 sind durch Tiefziehen aus einer Aluminiumfolie mit einem zylindrischen Rand 7,8 hergestellt, der durch Heisssiegeln mit der Innenschicht 9 des Behälterrumpfes 2 verbunden ist. Der Membranboden 3 ist durch eine Kartonrondelle 10, z.B. aus Wellkarton, geschützt, die an ihrem Umfang von dem zylindrischen Rand 7 der Bodenmembran 3 eingeschlossen ist und dort durch den leicht nach innengedrückten Randwulst 12 des Behälterrumpfes 2 gehalten wird. Die Deckelmembran 5 ist durch einen Napfdeckel 13 geschützt, der nach Entfernen der Deckelmembran 5 entlang einer nichtdargestellten Solltrennlinie zum Wiederverschliessen des Verpackungsbehälters dienen kann. Diese Solltrennlinie kann z.B. durch die linienförmig verlaufende Siegelverbindung des Membranrandes 8 mit der Innenschicht 9 des Behälterrumpfes 2 gebildet sein. Die Aussenseite des Kartonrumpfes 2 ist von einer als Verzierungs- und Beschriftungsträger dienenden Etikette 19 ummantelt.The packaging container has, for example in accordance with the illustrated embodiments, a circular cylindrical container body 2, which has been produced by cutting from a wound tubular body. A bottom membrane 3 closes one end 4 and a lid membrane 5 closes its other end 6. Both membranes 3, 5 are produced by deep drawing from an aluminum foil with a cylindrical edge 7, 8, which is heat-sealed to the inner layer 9 of the container body 2 . The membrane bottom 3 is covered by a cardboard disc 10, e.g. Protected from corrugated cardboard, which is enclosed on its circumference by the cylindrical edge 7 of the bottom membrane 3 and is held there by the slightly inwardly pressed edge bead 12 of the container body 2. The cover membrane 5 is protected by a cup cover 13 which, after the cover membrane 5 has been removed, can serve to reclose the packaging container along a nominal separation line (not shown). This target dividing line can e.g. be formed by the linear sealing connection of the membrane edge 8 with the inner layer 9 of the container body 2. The outside of the cardboard body 2 is encased by a label 19 which serves as an ornament and label carrier.

Die Innenschicht 9 des Behälterrumpfes 2 aus Aluminium mit einer Trägerschicht 11 aus Papier wurde ebenso wie seine aus wesentlich dickerem bandförmigem Kartonmaterial gewikkelte Aussenschicht 14 aus einem Folienband schraubenförmig so gewickelt, dass die aneinandergrenzenden, entlang der Schraubenlinie 15 sich erstreckenden Bandränder sich als Ueberlappungsränder 16,17;16',17';16'',17'' gegenseitig entsprechend den Darstellungen der Fig.3 bis 5 überlappen. Diese Ueberlappungsränder sind zur Bildung einer gasdichten Innenschicht 9 miteinander verleimt. Gemäss der Erfindung ist die Verleimung jedoch nur entlang eines von der Randkante 18,18',18'' des Folienbandes aus zurückversetzten schmalen Verleimungsstreifens 20,20',20'' vorgesehen, so dass ein äusserer Randbereich 21,21',21'' des auf der Behälterinnenseite überlappenden Randes verbindungslos an der darunterliegenden Oberfläche anliegt. Dies hat zur Folge, dass beim Herausreissen der mit der Innenschicht 9 des Behälterrumpfes 2 verbundenen Bodenmembran 3 dieser Randbereich 21,21',21'' der Bodenmembran 3 zuerst folgt und anschliessend durch eine Pellbewegung die Verleimung 20,20', 20'' zerstört wird, so dass sich die gesamte Innenschicht 9 in Form ihres Folienbandes aus dem Behälterrumpf 2 leicht herausziehen lässt.The inner layer 9 of the container body 2 made of aluminum with a carrier layer 11 made of paper, like its outer layer 14 made of much thicker tape-like cardboard material, was wound helically from a foil tape in such a way that the adjoining tape edges extending along the helix 15 extend as overlap edges 16, 17 ; 16 ', 17'; 16 '', 17 '' overlap one another in accordance with the representations of FIGS. 3 to 5. These overlap edges are used to form a gas-tight Inner layer 9 glued together. According to the invention, however, the gluing is only provided along a narrow gluing strip 20, 20 ', 20''set back from the edge 18, 18', 18 '' of the film strip, so that an outer edge region 21, 21 ', 21'' of the overlapping edge on the inside of the container lies without connection on the underlying surface. As a result, when the bottom membrane 3 connected to the inner layer 9 of the container body 2 is torn out, this edge region 21, 21 ', 21''of the bottom membrane 3 follows first and then destroys the gluing 20, 20', 20 '' by a pellet movement is so that the entire inner layer 9 can be easily pulled out of the container body 2 in the form of its film strip.

Fig.8 zeigt die Anfangsphase der Abpellbewegung der Innenschicht 9. Zuerst löst sich mit der Bodenmembran 3 der unversiegelt bzw. unverklebt am Behälterrumpf 2 anliegende, spitz auslaufende Zipfelbereich 30 der Innenschicht 9 und anschliessend setzt sich die Abpellbewegung über die fortschreitende Pellinie 32 fort und legt dabei die innere Kartonoberfläche 31 des Behälterrumpfes 2 zunehmend frei, bis das Folienstück der Innenschicht 9 mit der in Fig.2 gezeigten Form vollständig entfernt ist, um dem Aluminiumabfall zugeführt zu werden.8 shows the initial phase of the peeling movement of the inner layer 9. First of all, the pointed membrane portion 30 of the inner layer 9 unsealed or unsealed on the container body 2 loosens with the bottom membrane 3, and then the peeling movement continues over the advancing peeling line 32 and continues the inner carton surface 31 of the container body 2 becomes increasingly free until the film piece of the inner layer 9 with the shape shown in FIG. 2 is completely removed in order to be fed to the aluminum waste.

Um sicher zu verhindern, dass beim Herausreissen des Folienbandes der Innenschicht 9 dieses seitlich einreisst und folglich abreisst, so dass ein Teil der Innenschicht am Behälterrumpf zurückbleibt, ist der Randbereich 21 ,21',21'' des Folienbandes der Innenschicht 9 entsprechend den Ausführungsformen der Fig.3 bis 5 verstärkt. Nach Fig.3 ist hierfür der Randbereich 21 zu dem darunterliegenden Rand 17 hin nach innen gefalzt.In order to reliably prevent the inner layer 9 from tearing out when the film strip is torn out and consequently tearing off, so that part of the inner layer remains on the container body, the edge region 21, 21 ′, 21 ″ of the film layer of the inner layer 9 is in accordance with the embodiments of FIGS Fig. 3 to 5 reinforced. According to FIG. 3, the edge region 21 is folded inwards towards the edge 17 underneath.

Gemäss Fig.4 wurde ein zusätzliches Aufreissband 23 beim Wickeln zwischen die sich überlappenden Ränder 16',17' eingelegt und dabei mit der Innenseite des Randbereichs 16' verklebt. Dieses Aufreissband 23 erstreckt sich durch seinen schraubenlinienförmigen Verlauf bis zu der Bodenmembran 3, und sein Ende ist mit ihr verklebt, so dass es die Ablösung der Innenschicht 9 einleitet. Beim Ausführungsbeispiel nach Fig.5 wird der Randbereich 21'' des Folienbandes der Innenschicht durch ein Verstärkungsband 24 umschlossen. Ein Herausreissen der Innenschicht mit der Bodenmembran 3 ist nicht erforderlich, da sich der beim Lösen der Bodenmembran 3 hochgezogene spitze Zipfelbereich 30 der Innenschicht 9 zum weiteren Herausreissen von Hand anbietet. Die Herausreissbarkeit der Innenschicht 9 kann jedoch auch durch Einfärben des Aufreissbandes 23, des Verstärkungsbandes 24 oder des unverbundenen Ueberlappungsrandes 21 der Innenschicht 9 oder durch dort vorgesehene Beschriftungen deutlich gemacht werden.According to FIG. 4, an additional tear tape 23 was inserted during the winding between the overlapping edges 16 ', 17' and thereby with the inside of the edge area 16 ' glued. This tear tape 23 extends through its helical course to the bottom membrane 3, and its end is glued to it, so that it initiates the detachment of the inner layer 9. In the exemplary embodiment according to FIG. 5, the edge region 21 ″ of the film strip of the inner layer is enclosed by a reinforcing strip 24. It is not necessary to tear out the inner layer with the base membrane 3, since the pointed tip region 30 of the inner layer 9, which is pulled up when the base membrane 3 is detached, offers itself for further removal by hand. The tearing out of the inner layer 9 can, however, also be made clear by coloring the tear tape 23, the reinforcing tape 24 or the unconnected overlap edge 21 of the inner layer 9 or by the labels provided there.

Das Herausreissen der Bodenmembran 3 erfolgt durch Ziehen an einem Grifflappen 25,26, der gemäss Fig.1 und 8 an dem den Behälterquerschnitt überspannenden Membranteil und gemäss Fig.9,10 aussen an den Membranrand angeformt ist. Beim Herausziehen der Bodenmembran 3 durch Ziehen an dem Grifflappen 25 oder 26 wird die Kartonrondelle 10 mit herausgezogen. Beim Ausführungsbeispiel nach Fig.1 und 8 ist entsprechend der Grifflappen 25 auch in der Kartonrondelle 10 an gleicher Stelle vorgesehen, so dass beide sich überdekken.The bottom membrane 3 is torn out by pulling on a grip tab 25, 26 which, according to FIGS. 1 and 8, is formed on the membrane part spanning the container cross section and, according to FIGS. 9, 10, on the outside of the membrane edge. When pulling out the bottom membrane 3 by pulling on the grip tab 25 or 26, the cardboard disc 10 is also pulled out. In the exemplary embodiment according to FIGS. 1 and 8, the grip tab 25 is also provided in the cardboard rondelle 10 in the same place, so that both overlap.
