Abstract

The base (2) of the dish-shaped body (1) which is suction moulded is curved convex towards the inside (3). The side wall is inclined to the base (2) so that it forms an angle of 90 degs with the tangent of curvature (T) adjoining the base. The side walls can be corrugated (5) so that they fit better against the object. When an object is inserted in the container the side walls of the latter straighten out and adjoin the object. <IMAGE>

Description

Die Erfindung betrifft einen Verpackungsbehälter bestehend aus einem schalenförmigen, im Saugformverfahren aus insbesondere Altpapier- und Kartonagenabfällen gebildeten Formkörper.The invention relates to a packaging container consisting of a shell-shaped molded body formed by suction molding from waste paper and cardboard waste in particular.

Derartige Verpackungsbehälter sind hinlänglich bekannt und in Benutzung, so daß es diesbezüglich keines besonderen druckschriftlichen Nachweises bedarf. Unter "insbesondere aus Altpapier- und Kartonagenabfällen" ist zu verstehen, daß solche Formkörper auch aus Fasern auf Zellulosebasis oder auch aus Gemischen aus Fasern und solchen Abfällen bestehen können.Such packaging containers are well known and in use, so that no special printed evidence is required in this regard. "In particular from waste paper and cardboard waste" is to be understood that such shaped articles can also consist of fibers based on cellulose or else of mixtures of fibers and such waste.

Solche schalenförmigen Behälter haben entweder in bezug auf ihren Boden mehr oder weniger stark geneigte Seitenwände und können dadurch ineinandergestapelt werden, was aber dann mit dem Nachteil verbunden ist, daß die Seitenwände am einzusetzenden Gegenstand (entsprechend anagepaßte Formgebung vorausgesetzt) nicht anliegen. Es ist aber auch möglich und bekannt, die Seitenwände in bezug auf den Boden nahezu senkrecht anzuordnen, wodurch die Seitenwände zwar praktisch genau an den Gegenstandsseitenwänden anliegen und diesen insoweit gut fixieren bzw. umschließen, andererseits sind aber dadurch solche Verpackungsbehälter nicht mehr stapelbar.Such bowl-shaped containers either have more or less inclined side walls with respect to their base and can thereby be stacked one inside the other, which is then associated with the disadvantage that the side walls do not lie against the object to be used (provided the shape has been adapted accordingly). However, it is also possible and known to arrange the side walls almost vertically with respect to the floor, as a result of which the side walls lie practically exactly against the object side walls and in this respect fix or enclose them well, on the other hand, however, such packaging containers are no longer stackable.

Der Erfindung liegt demgemäß die Aufgabe zugrunde, diese dahingehend zu verbessern bzw. auszuformen, daß beide Bedingungen erfüllt werden können.The invention is accordingly based on the object of improving or shaping it in such a way that both conditions can be met.

Diese Aufgabe ist mit einem Verpackungsbehälter der eingangs genannten Art nach der Erfindung dadurch gelöst, daß der Boden des Formkörpers zu dessen Innenraum hin konvex gewölbt ausgebildet und die Seitenwandung des Formkörpers derart zum Boden geneigt angestellt ist, daß die Seitenwandung mit der Wölbungstangente im Ansatzbereich zum Boden einen Winkel von 90° bildet.This object is achieved with a packaging container of the type mentioned according to the invention in that the bottom of the shaped body is convexly curved toward the interior thereof and the side wall of the shaped body is inclined so that the side wall with the bulge tangent in the attachment area to the floor forms an angle of 90 °.

Setzt man in einen solchen Verpackungsbehälter einen formentsprechenden und damit zu verpackenden Gegenstand ein und drückt diesen gegen den Boden, so richten sich die Seitenwände zumindest in Teilbereichen senkrecht auf und legen sich an den Gegenstand an. Um dieses Aufrichten in Teilbereichen gewissermaßen "geordnet" vor sich gehen zu lassen, ist die Seitenwandung vorteilhaft mit Wellungen versehen, so daß sich die ringsum vorhandene Seitenwand gezielt verformen kann und sich mit den gegen den Gegenstand gerichteten Wellenbergen an diesen anlegt, während die abgewandten Wellentäler die Umfangsveränderung der Seitenwand aufnehmen. Im übrigen ist dieser Effekt nicht nur bei kreisförmigen Verpackungsbehältern erzielbar, sondern auch bei im Querschnitt rechteckigen Behältern.If one inserts a shape-matching and thus packaged object in such a packaging container and presses the latter against the floor, the side walls straighten up, at least in some areas, and lay against the object. In order to allow this straightening to take place in an "orderly" manner in some areas, the side wall is advantageously provided with corrugations, so that the surrounding side wall can deform in a targeted manner and bears against it with the wave crests directed against the object, while the opposite troughs absorb the change in circumference of the side wall. In addition, this effect can be achieved not only with circular packaging containers, but also with containers with a rectangular cross section.

Die Notwendigkeit, bei bekannten schalenförmigen Verpackungsbehältern mit geneigten Seitenwandungen besondere Formgebungen vorsehen zu müssen bspw. in Form von in den Innenraum ragenden Vorsprüngen, die direkt am Gegenstand anliegen, entfällt durch die erfindungsgemäße Ausbildung, da sich bei Belastung des konvex nach innen gewölbten Bodens der Seitenwand, ähnlich wie ein sich schließender Blütenkelch, diese am Gegenstand anlegt.The need to provide special shapes in known bowl-shaped packaging containers with inclined side walls, for example in the form of projections protruding into the interior, which are in direct contact with the object, is eliminated by the design according to the invention, since when the bottom of the side wall is convexly curved inwards, , similar to a closing calyx, which attaches to the object.

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

Der Verpackungsbehälter besteht aus einem schalenförmigen, im Saugformverfahren aus insbesondere Altpapier- und Kartonagenabfällen gebildeten Formkörper 1. Diesbezüglich nähere Erläuterungen, was das Saugformverfahren und das Rohmaterial betrifft, sind entbehrlich, da hinlänglich bekannt.The packaging container consists of a shell-shaped molded body 1, which is formed in the suction molding process from waste paper and cardboard waste in particular. As far as the suction molding process and the raw material are concerned, they are not necessary because they are well known.

Für einen solchen schalenförmigen Verpackungsbehälter ist nun, und wie aus Fig. 1 ersichtlich, wesentlich, daß der Boden 2 des Formkörpers 1 zu dessen Innenraum 3 hin konvex gewölbt ausgebildet ist und die Seitenwandung 4 des Formkörpers 1 derart zum Boden 2 geneigt angestellt ist, daß die Seitenwandung 4 mit der Wölbungstangente T in Ansatzbereich A zum Boden 2 einen Winkel von 90° bildet.For such a bowl-shaped packaging container, it is essential, and as can be seen from FIG. 1, that the bottom 2 of the molded body 1 is convexly curved toward its interior 3 and the side wall 4 of the molded body 1 is inclined to the bottom 2 such that the side wall 4 forms an angle of 90 ° with the bulge tangent T in the attachment area A to the base 2.

Die Seitenwand hat also gewissermaßen die Form eines Trichters, wodurch solche Verpackungsbehälter ineinandergestapelt werden können.The side wall thus has the shape of a funnel, so that such packaging containers can be stacked one inside the other.

Zweckmäßig ist die Seitenwandung 4 aus den genannten Gründen, und dies gilt insbesondere für kreisförmige Verpackungsschalen, mit Wellungen 5 versehen, so daß sich diese, wie in Fig. 3 angedeutet, geordnet an den Gegenstand G anlegt. Der gestrichelte Umfangskreis entspricht dabei der ursprünglichen Form, die, wie vorerwähnt, schon in etwa mit solchen Wellungen 5 versehen sein kann, die sich aber dann bei eingesetztem Gegenstand stärker und wie dargestellt, verformen.The side wall 4 is expedient for the reasons mentioned, and this applies in particular to circular packaging trays, with corrugations 5, so that, as indicated in FIG. The dashed circumferential circle corresponds to the original shape, which, as mentioned above, can already be provided with such corrugations 5, but which then deform more strongly when the object is inserted and as shown.

Bei einem im Querschnitt rechteckigen Verpackungsbehälter gemäß Fig. 4 sind solche "Vorwellungen" nicht zwingend erforderlich, da sich hierbei die Seitenwandungen 4, wie in Fig. 4 gestrichelt angedeutet, bei auf dem gewölbten Boden 2 aufgesetzten Gegenstand, an dessen Seitenwände anlegt, und zwar in Form einer den mittleren Bereich erfassenden großen Einbiegung. Die Eckbereiche EB behalten dabei ihre ursprüngliche Form weitgehend bei.In the case of a packaging container with a rectangular cross section according to FIG. 4, such “pre-corrugations” are not absolutely necessary, since here the side walls 4, as indicated by dashed lines in FIG. 4, bear against the side walls of an object placed on the curved bottom 2, namely in the form of a large inflection covering the central area. The corner areas EB largely retain their original shape.
