Plattenförmiges FormteilPlate-shaped molded part

Die vorliegende Erfindung betrifft ein plattenförmiges Formteil aus einem Kern aus nachwachsenden Rohstoffen, wie z.B. Stroh, Kokosfasern, Flachs oder dergleichen und einer beidseitigen Decklage aus Materialien aus ebenfalls nachwachsenden Rohstoffen, wie z.B. Jute, Leinen, Papier oder dergleichen, wobei der Kern mit den Decklagen durch Steppnähte verbunden ist.The present invention relates to a plate-shaped molded part made of a core made of renewable raw materials, such as straw, coconut fibers, flax or the like, and a cover layer on both sides made of materials also made of renewable raw materials, such as jute, linen, paper or the like, wherein the core is connected to the cover layers by quilting seams.

Plattenförmige Formteile der vorerwähnten Art sind an sich bekannt. Derartige Formteile werden üblicherweise nach Art eines Endlos-Stranges gefertigt und, sofern das Formteil einen rechteckigen Grundriß aufweisen soll, von diesem Endlos-Strang abgeschnitten. Werden andere Grundrißformen gewünscht, so können aus dem Strang auch entsprechende geometrische Formen geschnitten werden.Plate-shaped molded parts of the aforementioned type are known per se. Such molded parts are usually manufactured in the form of a continuous strand and, if the molded part is to have a rectangular outline, cut from this continuous strand. If other outline shapes are desired, corresponding geometric shapes can also be cut from the strand.

Nachteilig ist bislang, daß derart hergestellte Formteile zumindest zwei zunächst offene Stirnkanten aufweisen. Diese offenen Stirnkanten werden in der Praxis bisher dadurch geschlos-The disadvantage so far is that molded parts produced in this way have at least two initially open front edges. In practice, these open front edges have so far been closed by

zunächst offenen Stirnkanten sind Formteile der gattungsgemäßen Art bislang relativ instabil und somit nur für gewisse Einsatzzwecke verwendbar.Due to their initially open front edges, moulded parts of this type are currently relatively unstable and can therefore only be used for certain purposes.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein plattenförmiges Formteil der gattungsgemäßen Art zu schaffen, welches preiswert herstellbare, verschlossene Kanten aufweist und darüber hinaus auch weitestgehend eigensteif ist.The present invention is based on the object of creating a plate-shaped molded part of the generic type, which has closed edges that can be produced inexpensively and is also largely inherently rigid.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß alle offenen Stirnkanten des Formteiles durch eine aus kompostierbarem Kunststoff, vorzugsweise Polyurethan-Füllschaum bestehende, angeschäumte Randkante versiegelt sind.This object is achieved according to the invention in that all open front edges of the molded part are sealed by a foamed edge made of compostable plastic, preferably polyurethane filling foam.

Das Verschließen der offenen Stirnkanten eines derartigen Formteiles kann maschinell erfolgen und führt zu dem Vorteil, daß eine saubere und geometrisch vorherbestimmbare Kantenform realisiert werden kann. Außerdem wird durch die angeschäumten Randkanten eine Stabilisierung des plattenförmigen Formteiles erreicht, so daß dessen Verwendungszweck bzw. Verwendungsmöglichkeit erheblich erweitert wird.The open front edges of such a molded part can be closed mechanically and has the advantage that a clean and geometrically predeterminable edge shape can be achieved. In addition, the foamed edges stabilize the plate-shaped molded part, so that its intended use and possible uses are significantly expanded.

So kann ein derartiges Formteil beispielsweise als Verpackungsmaterial, als Polstermaterial, zur Schallisolierung, zur Wärmeisolierung, im Filterbau oder dergleichen eingesetzt werden und weist den letztendlich beträchtlichen Vorteil auf, daß es ins- - gesamt kompostierbar ist und somit bequem und praktisch entsorgt werden kann, falls es nicht mehr benötigt wird.Such a molded part can be used, for example, as packaging material, as upholstery material, for sound insulation, for heat insulation, in filter construction or the like and ultimately has the considerable advantage that it is completely compostable and can therefore be disposed of conveniently and practically if it is no longer needed.

Weitere Merkmale der Erfindung sind Gegenstand von Unteransprüchen .Further features of the invention are the subject of subclaims.

Ausführungsbeispiele der Erfindung sind in der beigefügten Zeichnung dargestellt und ■werden im folgenden näher beschrieben. Embodiments of the invention are shown in the accompanying drawings and are described in more detail below.

In Figur 1 ist mit dem Bezugszeichen 1 insgesamt ein plattenförmiges Formteil bezeichnet, welches aus einem Kern 2 aus nachwachsenden Rohstoffen, wie z.B. Stroh, Kokosfasern, Flachs oder dergleichen und aus einer beidseitigen bzw. allseitigen Decklage 3 aus Materialien aus ebenfalls nachwachsenden Rohstoffen, wie z.B. Jute, Leinen, Papier oder dergleichen besteht. Der Kern 2 ist mit den Decklagen 3 durch Steppnähte 4 verbunden, wodurch eine Verschiebung der innerhalb der Decklagen 3 befindlichen Kernmaterialien vermieden wird.In Figure 1, the reference number 1 designates a plate-shaped molded part, which consists of a core 2 made of renewable raw materials, such as straw, coconut fibers, flax or the like, and a cover layer 3 on both sides or all sides made of materials also made of renewable raw materials, such as jute, linen, paper or the like. The core 2 is connected to the cover layers 3 by quilting seams 4, which prevents the core materials located within the cover layers 3 from shifting.

Beim Ausführungsbeispiel gem. Figur 1 handelt es sich um ein Formteil 1 in rechteckiger Grundrißform. An seinen Längskanten ist das Formteil 1 durch die Decklagen 3 geschlossen, während an seinen beiden Stirnkanten erfindungsgemäß angeschäumte Randkanten 5 vorgesehen sind, durch welche die zunächst offenen Stirnkanten versiegelt sind. Diese angeschäumten Randkanten 5 bestehen aus einem kompostierbaren Kunststoff, vorzugsweise aus Polyurethan-Füllschaum, so daß das gesamte Formteil 1 nach erfolgter Nutzung problemlos entsorgt werden kann. Durch die angeschäumten Randkanten 5 aus kompostierbarem Kunststoff, vorzugsweise Polyurethan-Füllschaum, wird die Formstabilität des Formteiles 1 wesentlich erhöht, so daß das in Figur 1 gezeigte Formteil ohne weiteres als Verpackungsmaterial, als Polstermatial, zur Schallisolierung, zur Wärmeisolierung, im Filterbau oder dergleichen eingesetzt werden kann.The embodiment according to Figure 1 is a molded part 1 with a rectangular outline. The molded part 1 is closed on its long edges by the cover layers 3, while foamed edge edges 5 are provided on its two front edges according to the invention, by which the initially open front edges are sealed. These foamed edge edges 5 consist of a compostable plastic, preferably polyurethane filling foam, so that the entire molded part 1 can be easily disposed of after use. The foamed edge edges 5 made of compostable plastic, preferably polyurethane filling foam, significantly increase the dimensional stability of the molded part 1, so that the molded part shown in Figure 1 can be used without further ado as packaging material, as padding material, for sound insulation, for heat insulation, in filter construction or the like.

In den Figuren 3 bis 7 sind weitere, beispielhaft gezeigte Querschnittsformen für die Randkanten 5 gezeigt. Figur 3 zeigt, daß der Querschnitt der Randkanten 5 rechteckig sein kann. In Figur 4 ist ein Ausführungsbeispiel gezeigt, bei dem die Randkanten 5 winkelförmig mit einem über das Formteil im übrigen hinaus vorstehenden Schenkel 5a ausgebildet sind.Figures 3 to 7 show further cross-sectional shapes for the edge edges 5, shown as examples. Figure 3 shows that the cross section of the edge edges 5 can be rectangular. Figure 4 shows an embodiment in which the edge edges 5 are angular with a leg 5a that protrudes beyond the rest of the molded part.

Figur 5 zeigt eine Randkante 5, die mit einem Falz 5b ausgestattet ist.Figure 5 shows a marginal edge 5 which is equipped with a fold 5b.

Die Form der Randkante 5 beim Ausführungsbeispiel nach Figur &bgr; kann als halbkreisförmig bezeichnet werden.The shape of the edge 5 in the embodiment according to Figure β can be described as semicircular.

In Figur 7 ist eine Randkante 5 dargestellt, deren geometrische Querschnittsform als Viertelkreisbogen bezeichnet werden kann. Außerdem weist das Ausführungsbeispiel nach Figur 7 die Besonderheit auf, daß in der Randkante 5 eine Holzleiste 8 eingebettet ist.Figure 7 shows a peripheral edge 5 whose geometric cross-sectional shape can be described as a quarter-circle arc. In addition, the embodiment according to Figure 7 has the special feature that a wooden strip 8 is embedded in the peripheral edge 5.

Eine derartige Holzleiste 8 kann selbstverständlich auch in Randkanten 5 anderer geometrischer Grundform eingebettet sein und dient dazu, ein erfindungsgemäßes Formteil durch Nägel oder Schrauben oder andere Verbindungsmittel mit einem anderen Bauteil zu verbinden. Durch eine eingebettete Holzleiste 8 wird die Kompostierbarkeit des gesamten Formteiles 1 nicht eingeschränkt. Such a wooden strip 8 can of course also be embedded in edge edges 5 of other basic geometric shapes and serves to connect a molded part according to the invention to another component using nails or screws or other connecting means. An embedded wooden strip 8 does not restrict the compostability of the entire molded part 1.

Hinsichtlich der geometrischen Grundrißformen des Formteiles 1 generell kann gesagt werden, daß diese rechteckig sein kann, daß aber auch jede beliebige andere geometrische Form wählbar ist. Insbesondere können auch kreisförmige Formteile gebildet werden, die dann eine umlaufende Randkante 5 erhalten, die an die Stirnkanten angeschäumt wird. Durch die angeschäumte Randkante 5 wird in jedem Falle ein sauberer Abschluß der Stirnkanten des Formteiles erzielt, gleichzeitig dient die angeschäumte Randkante 5 zur Stabilisierung des gesamten Formteiles.With regard to the geometric outline shapes of the molded part 1, it can generally be said that this can be rectangular, but that any other geometric shape can also be selected. In particular, circular molded parts can also be formed, which then receive a peripheral edge 5 that is foamed onto the front edges. The foamed edge 5 always ensures a clean finish to the front edges of the molded part, and at the same time the foamed edge 5 serves to stabilize the entire molded part.
