NL8603205A - Extruded plastic open-mesh trough for growing plants etc. - consists of long strip with parallel fold lines permitting rolling-up flat or flat-folded strip and having sides upright when unrolled - Google Patents

Abstract

The extruded plastic trough with open-mesh walls is intended for growing vegetables or plants in a substrate. It consists of a strip of open-mesh material with parallel fold lines such that, in the fully flat or inwardly folded flat condition, the strip can be rolled up lengthwise and, when unrolled, the sides assume their upright position under the action of the inherent stress. The strip may have two parallel fold lines (as shown), or three to provide a trough with parallel sides and triangular-section bottom, or more such fold lines to provide, e.g., two, parallel longitudinally connected troughs or a trough with double-walled sides.

Description

Self-erecting plastic mesh gutter.

The invention relates to a self-erecting plastic mesh gutter. The aforementioned mesh trough is obtained by extrusion. During this process or directly thereafter, folding lines are applied in the longitudinal and / or the width direction at fixed or variable distances from each other.

The mesh gutter thus obtained can be rolled up to desired lengths in flat form, but also in folded form.

The roll-up can take place on or without cores.

When the mesh gutter is rolled out, completely straight, even with 10 large lengths, the upright sides automatically rise from the folding lines. This is, of course, done rather gradually. With a roller, the width of which is equal to the bottom size of the gutter and the diameter of which is greater than twice the gutter height, the self-erecting of the gutter gutter sides can be done practically a minute.

After use of the mesh gutter, the gutter can be folded in using the folding lines and rolled up again compactly. In this form, the mesh gutter can easily be stored, transported, etc. The mesh gutter is suitable for many re-uses.

The mesh gutter can be made in rectangular, square, oblong, diamond, polygonal, round and many other mesh shapes and variable material thicknesses.

The upright sides can be smooth, beaded or unevenly finished at the top (sides).

Using the plasticity of the plastic for cooling, foil, Mies, film, etc. can then be adhered at that location, so that a more or less closed gutter is created, but with the practically the same self-erecting qualities and of course also with the possibility of compact roll up.

The object of the invention is based on the market demand for an open mesh gutter, which must be supplied in large form in long lengths and in which the upright side must be able to erect itself.

The object of the invention is based on the market demand for substrate cultivation in vegetable and ornamental cultivation for an open gutter gutter.

35 This mesh gutter must be supplied in a compact form.

It must be possible to lay it perfectly straight in great lengths, with the upright sides being able to erect itself. The mesh gutter must be easy to pick up and store compactly after use (cultivation season) and be suitable for many re-uses.

-3- Conclusions: Mesh gutter, characterized in that instead of two, three folding lines are provided, so that a triangular gutter is created. Mesh gutter, characterized in that instead of two four 5 folding lines are applied, so that a quadrangular gutter is created. Mesh gutter, characterized in that instead of two more folding lines are applied, so that more gutters are created next to each other. Mesh gutter, characterized in that the self-erecting upright sides do not have a net, but a closed structure, with or without incorporated length and / or height reinforcements and / or reinforcements. Mesh gutter, characterized in that instead of two four folding lines are arranged in the portion serving upwards sides, in order to realize a double-walledness of said upstanding sides. r B '' V 1 3
