Description

Die Erfindung betrifft einen Verpackungsbehälter für die Schutzumhüllung von Gegenständen, bestehend aus mindestens zwei den Behälterhohlraum mit ihren Formeintiefungen begrenzenden Formkörpern, die aus im Saugverfahren ausgeformten Altpapier- und/oder Kartonagenschnitzeln gebildet sind.The invention relates to a packaging container for the protective wrapping of objects, consisting of at least two molded bodies which delimit the container cavity with their mold recesses and which are formed from waste paper and / or cardboard chips formed by the suction process.

Formstücke für Verpackungszwecke sind allgemein und bspw. nach DE-U-87 14 602 und US-A-3 135 450 bekannt und in den unterschiedlichsten Formen, insbesondere was die Formeintiefungen betrifft für den genannten Zweck in Benutzung. Abgesehen von diesen, aus Pulpe oder Papierabfällen hergestellten Behältern gibt es aber auch solche, die aus geblähtem, kugelförmig strukturiertem, außerordentlich leichtem Kunststoff hergestellt werden. Solche Kunststofformstücke, aber auch die eingangs erwähnten, dienen dazu, einen Gegenstand innerhalb einer Kartonage oder einer Kiste so zu umschließen oder abzustützen, daß der Gegenstand in seiner eigentlichen Verpackung gut gehalten und gegell Stoß- oder Schlagbeeinträchtigungen geschützt wird. Diese bekannten, hinsichtlich ihrer Zweckbestimmung befriedigenden Verpackungsformstücke haben jedoch hinsichtlich ihres Materials beträchtliche Nachteile. Zu ihrer Gewinnung ist der Verbrauch und damit die chemische Umsetzung und Verarbeitung von Primärenergieträgern, nämlich Erdöl erforderlich. Eine Wiederverwendung oder ein Recycling ist nicht möglich. Für eine Verbrennung kommen derartige Formstücke wegen der damit verbundenen extrem starken Rauch- und insbesondere Rußentwicklung nicht in Frage, und eine Zersetzung bzw. Verrottung auf natürlichem Wege tritt bei Deponie nicht ein, d.h., derartige Formstücke erfüllen zwar ihren Zweck, sie sind aber unter den heutigen Umweltaspekten bezüglich ihrer weiteren Herstellung und Verwendung im Grunde nicht mehr zu vertreten. Als Ersatz für derartige Kunststofformstücke sind deshalb nach dem erwähnten DE-U-87 14 602 Verpackungsformstücke der eingangs genannten Art aus einem schalenförmigen Formkörper mit einseitiger, der Form des Gegenstandes angepaßter, mindestens einer Formeintiefung vorgeschlagen worden, wobei der aus weitgehend aufgelösten Papierschnitzeln bestehende Formkörper auf der Formeintiefungsseite mit einer weitgehend glatten, feinsiebartig strukturierten und relativ harten Oberfläche und auf der anderen Seite, die Formkörperoberflächenkontur im wesentlichen wiederholend grob formangepaßt ausgebildet sind. Unter "weitgehend glatter Oberfläche" ist dabei eine Strukturierung zu verstehen, die sich durch die Anlage der ersten Faserschichten am Ausformsieb ergibt. Ferner ist unter "auf der anderen Seite grob formangepaßt" beim vorbekannten Formkörper zu verstehen, daß sich auf der anderen Seite, also der Seite, die nicht am zu umhüllenden Gegenstand zur Anlage kommt, zwar die Formgestalt der Anlageseite wiederholt, diese aber so belassen ist, wie sie sich ergibt, wenn der Saugverfestigungsvorgang abgebrochen wird. Diese Seite ist bedingt durch die Art der speziellen Herstellung weicher als die glatte Oberfläche.Shaped pieces for packaging purposes are generally known, for example according to DE-U-87 14 602 and US-A-3 135 450, and are used in a wide variety of forms, in particular as regards the mold recesses, for the purpose mentioned. Apart from these containers, which are made from pulp or paper waste, there are also containers made from expanded, spherically structured, extremely light plastic. Such plastic moldings, but also those mentioned at the outset, serve to enclose or support an object within a cardboard box or box in such a way that the object is held well in its actual packaging and is protected against impact or impact damage. However, these known packaging moldings which are satisfactory in terms of their intended use have considerable disadvantages with regard to their material. To obtain them, the consumption and thus the chemical conversion and processing of primary energy sources, namely crude oil, is required. Reuse or recycling is not possible. Such shaped pieces are out of the question for incineration because of the extremely strong smoke and soot development associated with them, and decomposition or decomposition by natural means does not occur at landfill, ie, such shaped pieces serve their purpose, but they are among the basically no longer responsible for today's environmental aspects with regard to their further manufacture and use. As a replacement for such plastic moldings, packaging moldings of the type mentioned at the beginning of a bowl-shaped molded body with a one-sided mold shape adapted to the shape of the object and at least one mold depression have therefore been proposed according to DE-U-87 14 602, the one consisting of largely dissolved paper chips Shaped bodies on the mold recess side with a largely smooth, fine sieve-like structured and relatively hard surface, and on the other side, the shaped body surface contour is essentially repetitively roughly adapted to the shape. A "largely smooth surface" is to be understood as a structuring which results from the contact of the first fiber layers on the forming screen. Furthermore, "roughly adapted to the shape" on the other hand is to be understood in the case of the known shaped body that on the other side, that is to say the side which does not come into contact with the object to be encased, the shape of the contact side is repeated, but this is left as it is as it results when the suction consolidation process is stopped. Due to the nature of the special production, this side is softer than the smooth surface.

Für Versandzwecke, und zwar ohne dafür Umhüllungskartonagen benutzen zu müssen, die die anfallende Altpapierflut noch vergrößern, sind solche Formstücke nach dem genannten DE-U-87 14 602 nicht ohne weiteres geeignet, da die rauhen, nach außen gewandten Flächen für einen umhüllungslosen Versand denkbar ungeeignet sind und die Flankenwände der Formstücke bei Zusammenstellung frei nach außen ragen und der Bruchgefahr unterliegen. Außerdem wiederholen sich nach außen in Negativform die Formgebungen des Innenraumes, und zwar bedingt durch die Art der Herstellung im Saugverfahren. Dies ist nur durch Verwendung eines anderen Rohmaterials, nämlich geeignetem Kunststoff möglich, wie dies die Verpackungsbehälter bspw. nach dem DE-U-18 97 373 und US-A-3 213 037 zeigen. Unter Versand ist dabei sowohl Postversand in Einzelstücken, aber auch bspw. Transport auf Paletten in gestapelter Vielzahl zu verstehen.For shipping purposes, and without having to use wrapping cardboard boxes that increase the amount of waste paper, such fittings according to DE-U-87 14 602 are not readily suitable, since the rough, outward-facing surfaces are conceivable for wrapping-free shipping are unsuitable and the side walls of the fittings protrude freely when assembled and are subject to risk of breakage. In addition, the shapes of the interior are repeated outwardly in negative form, due to the nature of the production using the suction process. This is only possible by using a different raw material, namely a suitable plastic, as shown by the packaging containers, for example according to DE-U-18 97 373 and US-A-3 213 037. Shipping is understood to mean both mailing in individual pieces but also, for example, transport on pallets in a stacked variety.

Der Erfindung liegt deshalb, ausgehend von Formstücken der eingangs genannten Art die Aufgabe zugrunde, diese dahingehend zu verbessern und zu stabilisieren, daß sie für einen umhüllungslosen Versand als Verpackungsbehälter geeignet sind, keine frei abragenden Flanken und keine nach außen wiederholte Negativausformungen aufweisen und daß der aus den Formstücken gebildete Verpackungsbehälter, obgleich im Saugformverfahren hergestellt, sowohl innen wie außen glatte Flächen aufweist.The invention is therefore based on fittings of the type mentioned the task of improving and stabilizing them in such a way that they are suitable for wrapping without wrapping as packaging containers, have no cantilevered flanks and no externally repeated negative formations and that the the fittings formed Packaging containers, although manufactured using the suction molding process, have smooth surfaces both inside and outside.

Diese Aufgabe ist mit einem Verpackungsbehälter der eingangs genannten Art nach der Erfindung durch die im Kennzeichen des Anspruches 1 angeführten Merkmale gelöst. Vorteilhafte und praktische Ausführungsformen ergeben sich nach den Unteransprüchen.This object is achieved with a packaging container of the type mentioned according to the invention by the features stated in the characterizing part of claim 1. Advantageous and practical embodiments result from the subclaims.

Durch diese erfindungsgemäße Ausbildung ergibt sich ein Verpackungsbehälter, der sowohl innen wie außen "glatte" Außenwände aufweist, der ausreichend stabil ist, einen Verpackungskarton ersetzen kann, und zwar verbunden mit der Möglichkeit, dabei trotzdem den Behälterhohlraum direkt an die Konturen des zu verpackenden Gegenstandes durch entsprechende Gestaltung des Saugformsiebes anpassen zu können, was dann bedeutet, daß keine zusätzlichen Stütz- oder Halteelemente beim Umhüllen des Gegenstandes in den Behälter mit eingebracht werden müssen. Da der Behälter keine rauhen Außenflächen mehr aufweist, ist damit auch die Postakzeptanz gegeben.This configuration according to the invention results in a packaging container which has both "inside" and outside "smooth" outer walls, which is sufficiently stable, can replace a packaging carton, combined with the possibility of nevertheless directing the container cavity directly to the contours of the object to be packed to be able to adapt the corresponding design of the suction mold sieve, which then means that no additional supporting or holding elements have to be introduced into the container when the object is wrapped. Since the container no longer has any rough outer surfaces, this also ensures post acceptance.

Da Formstücke der gattungsgemäßen Art gemäß genanntem DE-U-87 14 602 heute mit Wandstärken von 5 bis 6 mm herstellbar sind, haben diese sowieso eine relativ hohe Festigkeit, um direkt als Verpackungsbehälter für den Versand benutzt werden zu können, ohne daß es dazu einer zusätzlichen Umhüllungskartonage bedarf. Durch die erfindungsgemäß aufgebrachte Deckschale ergibt sich aber eine zusätzliche Versteifung insbesondere der Flankenwände.Since fittings of the generic type according to DE-U-87 14 602 can be produced today with wall thicknesses of 5 to 6 mm, these have a relatively high strength anyway, so that they can be used directly as packaging containers for shipping without it being one additional packaging is required. The cover shell applied according to the invention results in additional stiffening, in particular of the side walls.

Der erfindungsgemäße Verpackungsbehälter wird für den Versand entweder in üblicher Weise verschnürt oder zweckmäßiger mit Klebeband verschlossen. Dafür sind vorteilhaft in den glatten Außenflächen Klebeband- oder Schnurzugeintiefungen angeordnet, welche Verschlußmittel damit jeglicher äußerer Beeinträchtigung entzogen sind und diese auch keine Verhakungshindernisse beim Durchlaufen von bspw. mechanischen Förderanlagen darstellen. Im gleichen Sinne kann auch vorteilhaft in mindestens einer der Deckschalen in dessen Großfläche eine Anschrifteneintiefung angeordnet sein, wobei sich derartige Eintiefungen problemlos vorsehen lassen, da sich diese bei der Saugformherstellung automatisch mit ergeben, wenn das Formsieb entsprechend geformt ist. Um die gegeneinandergestellten Flanken der Formkörper bei Zusammenfügung des Behälters gegeneinander verrutschsicher auszubilden, können die Formkörper längs ihrer Öffnungsränder mit ineinandergreifenden Stufen versehen werden, was sich bei der Saugformherstellung ebenfalls ohne weiteres mit berücksichtigen läßt.The packaging container according to the invention is either tied up for shipping in the usual way or more appropriately sealed with adhesive tape. For this purpose, adhesive tape or cord pull indentations are advantageously arranged in the smooth outer surfaces, which closure means are thus removed from any external impairment and also do not represent any obstacles to snagging when passing through mechanical conveying systems, for example. In the same sense, an address indentation can also advantageously be arranged in at least one of the cover shells in its large area, such indentations being able to be provided without problems, since these are automatic during the production of the suction mold with result if the forming sieve is shaped accordingly. In order to form the mutually opposed flanks of the shaped bodies against slipping against one another when the container is assembled, the shaped bodies can be provided with interlocking steps along their opening edges, which can also easily be taken into account in the production of the suction mold.

Um die Großflächen des Behälters zusätzlich bei größeren Abmessungen zu stabilisieren bzw. zu versteifen, ist es im übrigen ohne weiteres möglich, die Formstückwände wabenartig zu strukturieren, wobei die wabenartigen Eintiefungen jedoch nur eine geringe Tiefe haben (höchstens Wandstärkentiefe), um eine im wesentlichen nur gering profilierte und versandfreundliche Außenfläche des Behälters beizubehalten.In order to additionally stabilize or stiffen the large areas of the container with larger dimensions, it is also readily possible to structure the shaped part walls in a honeycomb-like manner, the honeycomb-like depressions, however, only having a small depth (at most wall thickness depth) by essentially only to maintain low profile and shipping-friendly outer surface of the container.

Der neuartige Verpackungsbehälter wird nachfolgend anhand der zeichnerischen Darstellung von Ausführungsbeispielen näher erläutert.The novel packaging container is explained in more detail below with reference to the drawing of exemplary embodiments.

Der Verpackungsbehälter I besteht aus den Behälterhohlraum II begrenzenden Formkörpern 1, 2, die aus im Saugverfahren ausgeformtem Altpapier- und/oder Kartonagenschnitzel gebildet sind.The packaging container I consists of molded bodies 1, 2 delimiting the container cavity II, which are formed from waste paper and / or cardboard chips formed by the suction process.

Das spezielle Saugverfahren bedarf keiner näheren Erläuterung, da allgemein bekannt. Für ein solches Verpackungsbehälter ist nun unter Bezug auf Fig. 1, 2 wesentlich, daß der Behälter I aus mindestens zwei Formkörpern 1, 2 gebildet und jeder Formkörper als Hohlkörper ausgebildet ist, dessen Innenraum 4 mit einer Deckschale 6 aus dem gleichen Material abgeschlossen ist und wobei die glatten Seiten 3 jedes Formkörpers 1, 2 und der zugehörigen Deckschalen 6 die Innen- und Außenflächen 3' des Behälters I bilden, während die rauhen Flächen 1', 2', 6' gegen die Hohlräume 4 der Formkörper 1, 2 gerichtet sind.The special suction process requires no further explanation, as it is generally known. For such a packaging container, it is now essential with reference to FIGS. 1, 2 that the container I is formed from at least two molded bodies 1, 2 and each molded body is designed as a hollow body, the interior 4 of which is closed with a cover shell 6 made of the same material and the smooth sides 3 of each molded body 1, 2 and the associated cover shells 6 form the inner and outer surfaces 3 'of the container I, while the rough surfaces 1', 2 ', 6' are directed against the cavities 4 of the molded bodies 1, 2 .

Bevorzugt werden natürlich die Formkörper 1, 2 formidentisch ausgebildet, da dafür die gleiche Saugform benutzt werden kann.Of course, the shaped bodies 1, 2 are preferably of identical shape, since the same suction mold can be used for this.

Gemäß Fig. 5, 6 kann der Verpackungsbehälter I bspw. aber auch aus vier Formkörpern 1, 2 gebildet werden, die dann aufgrund ihrer Keilform im Sinne der Fig. 6 zu einem Verpackungsbehälter zusammengefügt werden können, der dann nur noch mit einem geeignet breiten Klebeband 20 für seinen Zusammenhalt zu umschließen ist. Der für die Umschließung eines Gegenstandes notwendige Innenraum 14 (pro Formkörper jeweils ein Viertel des Innenraumes bei dieser Ausführungsform) wird dabei, wie bspw. dargestellt, durch entsprechende Formgebung des Saugformsiebes jedes damit hergestellten Formkörpers gewonnen. Solche Ausbildungen, die natürlich auch andere Formen haben können, sind für Gegenstände gleicher Form vorgesehen die bspw. bei einer Serienfertigung anfallen und nur verpackt transportiert bzw. versandt werden müssen. Auch zylindrische Formgebungen mit entsprechend angepaßten Deckschalen sind auf diese Weise ohne weiteres herstell- und zu einem Behälter zusammenstellbar. Die formangepaßten Deckschalen 6 werden zweckmäßig mit den Formkörpern 1, 2 verklebt, diese Deckschalen 6 können beim Anliegen von Klebebändern 20 mit fixiert werden. Zweckmäßig geht man dabei so vor, daß man die beiden Formkörper 1, 2 zunächst an den Gegenstand anlegt und ringsum längs der Öffnungsränder 11 mit einem Klebeband 20 verbindet. Dann werden die Deckschalen 6 aufgelegt und bspw. mit kreuzweise angebrachten Klebebändern fixiert. Durch eine Verklebung wird die Handhabung des Verpackungsbehälters einfacher.5, 6, the packaging container I can, for example, also be formed from four molded bodies 1, 2, which can then be joined together to form a packaging container due to their wedge shape in the sense of FIG. 6, which then only has to be used with a suitably wide adhesive tape 20 is to be enclosed for its cohesion. The interior 14 necessary for enclosing an object (one quarter of the interior for each molded body in this embodiment) is obtained, as shown, for example, by appropriate shaping of the suction mold sieve of each molded body produced therewith. Such designs, which of course can also have other shapes, are provided for objects of the same shape which are produced, for example, in series production and only have to be transported or shipped in packaged form. Even cylindrical shapes with appropriately adapted cover shells can be easily produced and assembled into a container in this way. The form-fitting cover shells 6 are expediently glued to the shaped bodies 1, 2; these cover shells 6 can also be fixed when adhesive tapes 20 are applied. Appropriately, one proceeds in such a way that the two Shaped body 1, 2 first applied to the object and connected all around along the opening edges 11 with an adhesive tape 20. Then the cover shells 6 are placed on and, for example, fixed with crosswise applied adhesive tapes. The packaging container is easier to handle by gluing.

Zweckmäßig sind, und wie in Fig. 3 dargestellt, ein Formkörper und die zugehörige Deckschale 6 in Form eines Stückes 7 ausgeformt, wobei zwischen den beiden Teilen eine Falteintiefung 8 eingeformt ist, was bei der Saugausformung einfach dadurch erreicht werden kann, daß man dabei über diesen Bereich des Formsiebens in geringerer als Wandstärkendistanz eine entsprechend geformte Leiste als Blende anordnet. Längs dieser Falteintiefung 8 können dann der Formkörper 4 und die Deckschale 6 in Pfeilrichtung P zusammengeklappt werden und in dieser Stellung miteinander verklebt werden. Zweckmäßig ist dabei das Ganze so gestaltet, daß die Formeintiefungen in den Formkörpern 1, 2 als Stützen für die Deckschalen 6 dienen.Appropriately, and as shown in Fig. 3, a molded body and the associated cover 6 in the form of a piece 7, wherein a recess 8 is formed between the two parts, which can be achieved in the suction molding simply by doing that over arranges this area of the forming sieve in a smaller than wall thickness distance as a correspondingly shaped bar as an aperture. The shaped body 4 and the cover shell 6 can then be folded along this folding recess 8 in the direction of arrow P and glued together in this position. The whole is expediently designed such that the mold recesses in the moldings 1, 2 serve as supports for the cover shells 6.

Um den Behälter bequem umschnüren oder mit Klebeband 20 verschließen zu können, sind insbesondere die Deckschalen 6, wie in Fig. 2 dargestellt, mit bspw. sich kreuzenden Schnurzugeintiefungen 9 versehen, wobei auch zusätzlich eine Anschrifteneintiefung 10 vorgesehen werden kann. Abgesehen davon, daß derartige Eintiefungen mit zur Aussteifung beitragen, erstrecken sich dadurch Verschnürungen bzw. Klebebänder unterhalb der Oberflächenebenen und gewährleisten einen unbehinderten Transport durch bspw. Förderanlagen, wobei auch das Anschriftenfeld unbeeinträchtigt bleibt.In order to be able to conveniently strap around the container or seal it with adhesive tape 20, the cover shells 6, in particular, as shown in FIG. 2, are provided with, for example, intersecting cord pull indentations 9, and an address indentation 10 can also be provided. Apart from the fact that such depressions also contribute to the stiffening, strings or adhesive tapes extend below the surface levels and ensure unimpeded transport by, for example, conveyor systems, the address field also remaining unaffected.

Ebenso unproblematisch wie die Ausbildung derartiger Eintiefungen 9, 10 ist auch eine Oberflächenstrukturierung der Großflächen 6'' der Deckschalen 6, wie in Fig. 1 zum Teil angedeutet, in Form von Waben 13, deren Tiefe maximal der Wandstärke der Formkörper entspricht.Just as unproblematic as the formation of such depressions 9, 10 is also a surface structuring of the large areas 6 ″ of the cover shells 6, as indicated in part in FIG. 1, in the form of honeycombs 13, the depth of which corresponds at most to the wall thickness of the shaped bodies.

Um die beiden Formkörper 1, 2 im zusammengefügten Zustand gegeneinander zu sichern, können auch die Öffnungsränder 11 der Formkörper 4, wie in Fig. 4 dargestellt, als ineinandergreifbare Stufen 12 ausgebildet sein. Die Eintiefungen 9 können natürlich auch ringsum längs der Öffnungsränder 11 angeordnet sein, um dort ein Klebeband 20 ringsumlaufend anbringen zu können, was aber auch ohne solche Eintiefungen möglich ist.In order to secure the two molded bodies 1, 2 against one another in the assembled state, the opening edges 11 of the molded bodies 4, as shown in FIG. 4, can also be engaged Levels 12 may be formed. The depressions 9 can of course also be arranged all around along the opening edges 11 in order to be able to apply an adhesive tape 20 there all the way around, but this is also possible without such depressions.

Durch eine besondere Ausgestaltung des Formsiebes ist es, wie erwähnt, im übrigen auch möglich, an den Formkörpern 1, 2 (siehe Fig. 5) gegenstandsbezogene Halteelemente 14 bei der Saugherstellung mit vorzusehen, die sich als Stützzapfen 17 oder Querrippen im Innenraum der Formkörper 1, 2 erstrecken und im zusammengefügten Zustand den umschlossenen Gegenstand halten bzw. abstützen.Due to a special design of the forming sieve, it is also possible, as mentioned, to provide object-related holding elements 14 on the shaped bodies 1, 2 (see FIG. 5) during suction production, which are used as support pins 17 or transverse ribs in the interior of the shaped bodies 1 , 2 extend and hold or support the enclosed object in the assembled state.
