Abstract

Flexible hollow body is made from plastic films with spacing indentations which are (partially) connected to each other. One or more of the plastic films also have undulating indentations which extend linearly in >=1 direction and which render the plastic films expansible. The flexible hollow body may be connected to other expansible or flexible materials. The sec. indentations have a concertina-like function so that on expansion or compression of the film, not the expansibility, but only the flexibility of the film material is effected. When all the sec. indentations extend in one direction, the two films form a hollow body which is flexible in one direction and rigid in a direction perpendicular to it, as the indentations act as reinforcing ribs.

Description

Flexibler Hohlkörper aus KunststoffolienFlexible hollow body made of plastic films

Für verschiedene Einsatzzwecke werden Hohlkörper aus zwei Kunststoffolien verwendet, die durch einen Abstand zueinander, der durch noppen- oder rippenartige Ausprägungen meist in einer der Folien gehalten wird, einen Hohlraum bilden. Dieser Hohlraum dient z. B. bei der Verwendung zur Dränage zur Wasserableitung, oder bei Verwendung zur Wärmeisolierung als Luftschicht, oder in der Verpackungsindustrie als Pufferschicht.Hollow bodies are made from two plastic films for various purposes used by a distance to each other, which is by knob-like or rib-like Expressions are usually held in one of the foils to form a cavity. This Cavity serves z. B. when used for drainage for water drainage, or at Use for thermal insulation as an air layer, or in the packaging industry as a buffer layer.

Um die Tiefzieheigenschaften des Folienmaterials voll auszunutzen, um also mit möglichst dünnen Folien einen möglichst großen Hohlraum bei ausreichender Druckfestigkeit des Hohl körpers zu erzeugen, müßten beide Folien mit Ausprägungen versehen sein, wobei die Täler der Ausprägungen beider Folien einander entgegen gerichtet und zumindest zum Teil miteinander verbunden sein müßten. Diese Konstruktion ergibt jedoch wegen der beschränkten Dehnbarkeit des Folienmaterials einen Hohlkörper, der wegen seiner geringen Flexibilität für viele Zwecke nicht tauglich ist. Er läßt sich z. B. nur zu Rollen großen Durchmessers aufwickeln, die schwer zu handhaben und teuer zu transportieren sind.In order to take full advantage of the deep-drawing properties of the film material, So with the thinnest possible foils as large a cavity as possible with sufficient To generate compressive strength of the hollow body, both films would have to be stamped be provided, the valleys of the expressions of the two films opposing each other directed and at least partially connected to each other. This construction However, due to the limited elasticity of the film material, it results in a hollow body, which is not suitable for many purposes due to its low flexibility. He let z. B. only wind up to large diameter rolls that are difficult to handle and are expensive to transport.

Gegenstand der Erfindung ist ein Hohlkörper aus Kunststoffolien der zuletzt beschriebenen Bauart mit der zusätzlichen Eigenschaft Flexibilität. Die Flexibilität wird dadurch erreicht, daß eine oder beide Folien außer mit den abstandhaltenden Ausprägungen mit weiteren Ausprägungen versehen sind, die einen einfach eiförmigen oder einen beliebig geformten welligen Querschnitt haben und die sich linear über die Folie erstrecken. Diese Ausprägungen haben in ihrer Vielzahl die Funktion eines Faltenbalges, so daß bei Dehnung oder Stauchung der Folie nicht die Dehnbarkeit, sondern nur die Biegefähigkeit des Folienmaterials in Anspruch genommen wird. Wenn alle talförmigen Ausprägungen in einer Richtung verlaufen, bilden die beiden Folien einen Hohl körper, der in einer Richtung flexibel und in der dazu senkrechten Richtung biegesteif ist, da die Ausprägungen als zusätzliche Aussteifungsrippen wirken.The invention relates to a hollow body made of plastic films last described type with the additional property flexibility. the Flexibility is achieved in that one or both foils except with the spacer Characteristics are provided with other characteristics that are simply egg-shaped or have an arbitrarily shaped wavy cross-section and which extend linearly over extend the slide. In their multitude, these characteristics have the function of one Bellows, so that when the film is stretched or compressed, the stretchability, but only the flexibility of the film material is used. if all valley-shaped Forms run in one direction, form the two foils form a hollow body that is flexible in one direction and in that direction vertical direction is rigid, since the characteristics as additional stiffening ribs works.

Bei einer Ausführung des Hohlkörpers, der in allen Richtungen flexibel ist, verlaufen die Täler der Ausprägungen in verschiedenen, normalerweise in zwei zueinander senkrechten Richtungen. Um Kreuzungen der Ausprägungen an der Folienoberfläche, die die Faltenbalgwirkung aufheben würden, zu vermeiden, verlaufen die Täler der Ausprägungen in den Verbindungslinien der abstandhaltenden Ausprägungen, durch die sie jeweils unterbrochen werden. Bei der Biegung eines aus zwei derartig verformten Folien bestehenden Hohlkörpers wird seine Mittelfläche als "neutrale Faser" weder gereckt noch gestaucht.In an embodiment of the hollow body that is flexible in all directions is, the valleys of the manifestations run in different, usually in two mutually perpendicular directions. To avoid intersections of the characteristics on the film surface, which would cancel the bellows effect, to avoid the valleys of the Characteristics in the connecting lines of the spacing characteristics through which they are each interrupted. When bending one of two deformed in this way Foils existing hollow body is called its middle surface as "neutral fiber" neither stretched or compressed.

Der flexible Hohlkörper kann auch aus mehr als zwei Kunststoffolien der beschriebenen Art bestehen, also mehrere jeweils durch eine Kunststoffolie voneinander getrennte Hohlräume haben. Ein derartiger Hohlkörper ist in einer Richtung flexibel, in der dazu senkrechten biegesteif.The flexible hollow body can also consist of more than two plastic films exist of the type described, so several each by a plastic film from each other have separate cavities. Such a hollow body is flexible in one direction, rigid in the perpendicular to it.

Erfindungsgemäß können die flexiblen Hohikörper mit anderen, z. B.According to the invention, the flexible hollow body with other, for. B.

isolierenden Stoffen verbunden werden. Die Verbindung mit einem dehnbaren Stoff ergibt ein flexibles, die mit einem nur biegefähigen Stoff ein biegetöhiges Bauteil.insulating materials are connected. The connection with a stretchable Fabric results in a flexible one, while fabric that is only bendable results in a bendable one Component.

Fig. 1 zeigt einen in allen Richtungen flexiblen Hohlkörper aus zwei Kunststoffolien (1) mit abstandhaltenden Ausprägungen (2) und talförmigen Ausprägungen (3).Fig. 1 shows a flexible in all directions hollow body made of two Plastic films (1) with spacing-apart features (2) and valley-shaped features (3).

Fig. 2 stellt einen in einer Richtung flexiblen Hohlkörper aus drei Kunststoffolien dar.Fig. 2 shows a one-way flexible hollow body of three Plastic films.

Die durch die Erfindung erreichte Flexibilität ermöglicht das transportgünstige Aufrollen der beschriebenen Hohlkörper zu Rollen kleinen Durchmessers, das formschlüssige Verlegen auf unebenen Flächen und das Biegen um Ecken und Kanten.The flexibility achieved by the invention makes it easy to transport Rolling up the described hollow body to form small-diameter rolls, the form-fitting Laying on uneven surfaces and bending around corners and edges.
