Description

Title of the invention: vegetation support and its uses

Technical Field [0001] The present invention relates to the field of revegetation. It relates more particularly to a vegetation support composed of an envelope containing on the one hand, a substrate, and on the other hand, a plant material and / or a fungus, as well as its use for the growth of said plant material and / or the fungus.

Vegetation consists in covering an artificial surface with plants or fungi, preferably with herbaceous plants.

The return of nature is an important issue for the development of cities in a context of growing urbanization on a global scale. Many cities aim to develop the greening of buildings and to deploy urban agriculture projects. Indeed, the greening of cities is associated with many benefits. Above all, it is helping to combat the urban heat island effect and the increasing erosion of biodiversity. But it also reduces the state of stress and anxiety of city dwellers and educates people about biodiversity. By creating an attractive and pleasant environment, revegetation makes it possible to enhance the use of daily soft journeys by city dwellers (walking, cycling) and also increases the value of land and real estate.

Daily contact with nature, including on artificial surfaces such as balconies, terraces or window edges, in particular allows a reduction in blood pressure, a reduction in muscle tension and an improvement in productivity.

Thus, whether for municipalities or for individuals, there is a real desire to revegetate spaces, in particular through the use of revegetation supports adapted to the constraints of the city.

Conventional vegetation supports can for example be containers of the type pots, tubs, planter vases. These containers make it possible to cultivate above ground. Depending on their size, shape, material, they can vegetate exterior and / or interior surfaces, and adapt to large and small spaces.

Conventional vegetation supports have certain drawbacks well known to those skilled in the art.

Some materials such as for example terracotta have a high weight allowing them to withstand bad weather. However, terracotta has the disadvantage of being fragile and easily brittle in the event of a fall. Once broken, such containers will cause dispersion of the substrate and the plant material and / or fungi they contain.

The appearance of synthetic materials such as plastic has made it possible to resolve certain problems of fragility and weight of the supports. Such supports using materials from the exploitation of fossil fuels are easy to manufacture or transport and are inexpensive.

However, international awareness of environmental issues is gradually leading consumers to turn away from such products using non-recyclable materials.

Other greening media have been recently developed by startups.

PRIOR ART In outdoor vegetation, the start-up “Sous les fraises ™”, for example, develops vegetable and fruit gardens for cities. Its patent application WO2016162152 in particular discloses a porous support for cultivating an organism, comprising two walls which can receive water, the two walls being arranged to constitute at least one pocket for receiving the organism. Each wall of said porous support comprises at least one porous layer comprising a chemically inert and porous material, allowing water to flow by gravity through the pores of the layer, said layer being arranged to allow the organism to s 'grab it.

Advantageously, this support can be used as a wall support by fixing one of the walls to the wall of interest.

In indoor planting, the start-up "Prêt à Push ™" offers indoor gardens in the form of ready-to-grow kits requiring only regular watering. The concept is based on capsules containing a substrate and seeds. The capsule is placed on a vegetative support containing a floating part allowing the capsule to have all the water supplies necessary for plant growth. The vegetation support is provided with an automated lighting system allowing the plants to be exposed to enough light to grow.

This start-up is also developing a kit for mushrooms. This kit includes a cardboard box and a bag containing the substrate and the mushrooms. To activate the development of fungi, the user must cut a membrane giving him access to the substrate-mushroom mixtures and apply with a spray of water to moisten the medium.

The start-up "Mon petit coin vert ™" offers a kit containing geotextile vegetation supports, a substrate and seeds.

Geotextile pots are a modern alternative to plastic, ceramic or clay pots. Geotextile pots can come in different forms. The latter are perfectly suited for urban use, the pots are light, foldable, washable and reusable. The plant will be more resistant by producing shorter and more robust roots. The porosity of the geotextile pot allows the regulation of heat and humidity, thus avoiding overheating harmful to the plant. The porosity of the geotextile pot nevertheless forces the support to be placed on an absorbent surface or allowing it to evacuate water.

Other supports can take the form of bags such as the "GROW BAG ™" offered by the company NOTED ™ consist only of biodegradable materials. This all-in-one bag is made up of a container made of biodegradable fibers, a substrate and seeds for pre-growing plants. This completely permeable bag needs to be watered on an additional support to retain the water flowing from the support. Once the plant has grown sufficiently, the plant support can be planted directly in another support or in the soil.

The patent document CN1810084 discloses a vegetation support and its use in the ecological protection of mountains and the vegetation of sand. This vegetation support contains a plant material separately from the substrate. This separation is carried out by water-soluble coating sheets allowing the support to confine the substrate and the seeds until watering, activating the germination of plants. The outer layer of the support is made up of mesh allowing plants to grow as it passes through. The vegetation support is fully permeable and needs to be placed on a soil allowing the absorption of water or its flow.

Summary of the invention The present invention relates to the field of revegetation. It relates more particularly to a vegetation support composed of an envelope containing on the one hand, a substrate, and on the other hand, a plant material and / or a fungus, as well as its use for the growth of said plant material and / or the fungus. Technical problem Considering the foregoing, a problem which the present invention proposes to solve consists in developing a vegetation support which has in particular the advantage of being simple to use and of being easy to handle.

Such a vegetation support includes the three elements necessary for growing plants (the container, the substrate and the material) and is advantageously made from bio-based materials or from the circular economy, thus making it more environmentally friendly. environment or ecological ("environmentally friendly").

Technical solution The solution to this problem posed firstly is a vegetation support consisting of an envelope containing on the one hand, a substrate, and on the other hand, a plant material and / or a fungus, characterized in that said envelope comprises an impermeable lower part assembled with an upper part of which at least 1% of the surface is permeable and comprises a mesh whose mesh is between 250 μm (60 mesh) and 16,000 μm (5/8 mesh).

The second object is a water-soluble pocket comprising a plant material for support according to the invention.

Finally, the invention has as its last object the use of a support according to the invention, for the growth of a plant material and / or a fungus.

Benefits Provided The Applicant has in particular been able to develop a vegetation support which has qualities of lightness and flexibility combining containment of the substrate and permeability. In addition, the vegetation support has an impermeable part aimed at keeping the water in the support, and making it possible to keep a moist environment conducive to the good development of the plant material that it contains.

In this description, unless otherwise specified, it is understood that, when an interval is given, it includes the upper and lower bounds of said interval.

Description of the embodiments As is apparent in particular from the figures, the first object of the invention is a vegetation support composed of an envelope 2 containing on the one hand, a substrate 3, and on the other hand, a material vegetable 4 and / or a fungus.

A vegetation support 1 according to the invention designates a material element on and in which a plant material 4 and / or a fungus can develop.

According to the invention, the vegetation support 1 is composed of an envelope 2 which is a packaging or container, preferably made of flexible material making it possible to give its form to the support.

The envelope is thus a structure which is closed or closable by an opening and closing system, and which comprises two parts: a lower part 21 and an upper part 22.

The lower part 21 of the envelope corresponds to the part of the support which is in contact with the ground. It generally represents around 50% of the external surface of the support.

The lower part 21 is waterproof, that is to say that it does not allow a liquid or a fluid to escape. The lower part 21 thus makes it possible to confine within the envelope, before commissioning of the invention, all of the initial elements which constitute the substrate 3 and the plant material 4 and / or a fungus. When in use and especially when watering for the growth of plant material, this lower part prevents the liquid from escaping. This lower part 21 also makes it possible to direct the plant material during growth to a permeable part located on the upper part 22 of the envelope.

The lower part 21 of the casing 2 is composed of at least one layer of an impermeable material such as for example plastic, rubber, resin, fabrics (fibers, tarpaulins) which are impermeable or waterproofed.

The so-called waterproofed materials are permeable materials having been treated by a chemical or physical process allowing them to be sealed by means of water-repellent substances preventing them from being crossed by a liquid.

Preferably, the lower part 21 of the casing 2 is composed of fibers or of a sheet preferably originating from production lines using biobased elements or originating from recycling. It is possible to add a layer of geotextile in order to channel and facilitate the root development of the plant material.

Preferably, the textile of the impermeable lower part 21 of the envelope 2 is chosen from plant fibers such as linen, hemp, viscose, nylon, cotton, wool, silk, bamboo, Kapok, jute, ramie, sisal, coconut or synthetic fibers like nylon or acrylic which could be substituted by "bio-plastics". Even more preferably, the textile of the waterproof lower part 21 of the envelope is chosen from linen, hemp, viscose, nylon, acrylic, polyester.

The upper part 22 of the envelope corresponds to the aerial part of the support 1. It generally represents around 50% of the external surface of the support.

Said part 22 necessarily includes a permeable part, which can therefore be passed through or penetrated by a fluid or a liquid, especially by water. This permeable part makes it possible to insert a liquid, for example by watering, into the vegetation support 1. As illustrated in FIGS. 2, 4 and 8, this permeable part also allows the development and growth of a plant material 4 and / or a fungus.

The growth of the plant material is done through the meshes of the permeable upper part 22 of the envelope 2. In fact, the mesh of the mesh 5 is wide enough to leave fairly large openings allowing development for example of plants or fungi contained in the vegetation support 1.

The mesh according to the invention designates the opening that the nodes of the material or of the mesh 5 of the permeable upper part 22 leave between them.

The mesh of the mesh 5 is preferably between 250 pm (60 mesh) and 16000 pm (5/8 mesh). Below a mesh size of 250 µm, the growth of plant material is slowed down or even impossible. Above 16,000 µm, the substrate 3 or the plant material 4 escapes the support too easily.

Preferably, the mesh is between 250 pm (60 mesh) and 4760 pm (4 mesh). Even more preferably, the mesh is between 500 μm (35 mesh) and 2380 μm (8 mesh).

Furthermore, according to the invention, the upper part 22 consists of at least 1% of permeable surface, preferably 5% or 10%, more preferably still 30%.

According to a particular embodiment of the invention, 100% of the upper part 22 of the casing 2 is permeable.

According to the invention, the upper part 22 comprises at least 1% of permeable surface and a mesh 5 whose mesh is between 250 pm (60 mesh) and 16000 pm (5/8 mesh).

Preferably, the upper part 22 comprises at least 5% of permeable surface and a mesh 5 whose mesh is between 250 µm (60 mesh) and 16,000 µm (5/8 mesh).

More preferably, the upper part 22 comprises at least 10% of permeable surface and a mesh 5 whose mesh is between 250 pm (60 mesh) and 4760 pm (4 mesh).

Even more preferably, the upper part 22 comprises at least 30% of permeable surface and a mesh 5 whose mesh is between 500 μm (35 mesh) and 2380 μm (8 mesh).

The upper part 22 of the envelope is preferably composed of fibers from production lines using bio-based elements or from recycling.

Preferably, the fibers or meshes forming the upper part 22 of the envelope are chosen from plant fibers such as linen, hemp, viscose, nylon, cotton, wool, silk, bamboo, Kapok, jute, ramie, sisal, coconut or synthetic fibers like nylon, acrylic or textilene which could be substituted by "bio-plastics". Even more preferably, the fibers or meshes forming the upper part 22 of the envelope are chosen from linen, hemp, viscose, nylon, acrylic, polyester.

As shown in Figures 9, 10, 11 and 12, the upper part 22 of the casing 2 can also have an aesthetic function and in this case be composed for example of several pieces of textile sewn together, some parts of which can present a tighter mesh less conducive to plant growth but which will display different patterns or colors.

The waterproof lower part 21 and the upper part 22 of the casing 2 described above are assembled and thus allow the casing to be closed and to contain or pack the substrate 3 and the plant material 4 and / or the fungus. This assembly of the parts is preferably carried out by sewing or gluing. It is preferably waterproof.

This packaging or wrapping of the substrate 3 and of the plant material 4 and / or of the fungus makes it possible to avoid any dispersion of these elements during the handling of the support 1. The envelope 2 thus makes it possible in particular to avoid ingestion accidental substrate or vegetable matter by young children.

The envelope 2 of the vegetation support 1 according to the invention contains on the one hand a substrate 3 and on the other hand a vegetable material 4 or a fungus.

A substrate 3 according to the invention designates a mixture of materials serving as support for a plant organism and / or a fungus. The substrate according to the invention is preferably composed of a mixture of one or more elements preferably chosen from agricultural soil, potting soil, compost, plant fibers, inert materials, peat, wood, rock, sand, germinating discs, clay, pozzolan, dehydrated pancakes giving it characteristics of lightness, breathability and nutritional richness.

The components of the substrate are preferably chosen from among the elements resulting from the recycling of organic materials.

The substrate 3 serves both as a mechanical support for the rooting of the plant material, but also as a source of nutritive contributions for said plant material.

The substrate is generally in a solid and / or fluid form inside the envelope 2 of the support 1. The substrate also contributes to giving its shape to the support.

Of course, a person skilled in the art will adapt the composition of the substrate according to the nature of the plant material 4 or of the fungus used and to be grown.

Preferably, it is the combination between a wafer of dehydrated substrate of the JIFFY GROW BLOCK ™ type associated with seeds of flowering plants such as the seeds of petunias which will be preferred.

The substrate 3 may either be inserted directly into the envelope 2 by the mechanical opening and closing system 7 or else it may be integrated into the envelope 2 by using a refill as described below. below.

Advantageously, the substrate has qualities of lightness and flexibility. Thus, in the event of the support falling according to the invention, the risk of injury is limited.

According to the invention, plant material 4 denotes a plant fragment allowing a plant to be cultivated in a substrate by vegetative propagation (cuttings) or by sexual reproduction (seeds, spores).

The plant material according to the invention is preferably chosen from a seed, a spore, a rhizome, a bulb, a seedling, a leaf, a cutting, a root.

More preferably, the plant material 4 is a flower seed, an aromatic plant seed, a honey plant seed, a fruit and / or vegetable seed, a medicinal plant seed, fern spores, a flower rhizome, a flower bulb.

By way of non-limiting examples of flower seeds, mention may be made of seeds of Papaver rhoeas (Poppy), seeds of Viola Wittrockiana (Glow of the Alps) and seeds of Viola Comuta (Violets).

By way of nonlimiting examples of seeds of aromatic plants, mention may be made of Coriandrum Sativum seeds (Coriander), Ocimum Basilicum seeds (Basil), Mentha Piperita seeds (Peppermint) and seeds Thymus Vulgaris (Thyme).

By way of nonlimiting examples of seeds of melliferous plants, mention may be made of the seeds of Taraxacum officinale (Dandelion), the seeds of Lavandula angustifolia vera (Lavender) and the seeds of Phacelia tanacetifolia (Phacelia).

By way of non-limiting examples of fruit seeds, mention may be made of the seeds of Lycopersicon esculentum (Cherry tomato) and the seeds of Fragaria Vesca (Strawberry).

By way of non-limiting examples of vegetable seeds, mention may be made of seeds of Pisum sativum (Peas) and seeds of Capsicum annuum (Chili).

By way of nonlimiting examples of seeds of medicinal plants, mention may be made of the seeds of Melissa officinalis (Lemon balm), the seeds of Arnica montana (Arnica).

By way of nonlimiting examples of spores, mention may be made of the spores of Osmunda japonica (Japanese Osmonde), the spores of Phyllitis scolopendrium (Scolopendre fern) and the spores of Matteuccia struthiopteris (Ostrich fern).

By way of nonlimiting examples of flower rhizomes, mention may be made of the rhizomes of Convallaria majalis (Lily of the Valley), the rhizomes of Paeonia (Peony) and the rhizomes of Hemerocallis (Hemerocalle).

By way of nonlimiting examples of flower bulbs, we can cite the bulbs of Tulipa gesneriana (Tulip), the bulbs of Begonia Tuberhybrida (Begonia) and the bulbs of Dahlia Pompon (Dahlia ponpon).

Of course, the plant material 4 may be of a different nature depending on the use of the plant which is made of it.

The support object of the present invention is thus particularly suitable for growing ornamental plants (Flowers, Cat grasses) but also medicinal plants (Phytotherapy), food (Aromatic plants, fruits / vegetables) or useful for maintaining a biodiversity (honey plants, local flora).

As can be seen in FIGS. 5, 6 and 7, the substrate 3 is advantageously separated from the plant material 4 and / or from the fungus before use, by a separator 6.

Thus, the structural organization of the support can vary in that the separator 6 separating the plant material 4 and / or a fungus from the substrate 3 can be located at different positions.

The separator 6 according to the invention is preferably a film, a paper called "seeded" water-soluble and / or biodegradable or an organic water-soluble adhesive.

Alternatively, the separator 6 can also be a film around the plant material 4 of the "pellet" type.

As illustrated in Figure 7, the plant material 4 can be separated from the substrate 3 by a water-soluble pocket 8. The structural organization of the support can thus be modified provided that the substrate 3 and the plant material 4 and / or the fungus remains physically separated by the separator 6.

The Applicant was able to demonstrate that at the time of commissioning of the vegetation support, during the first supply of water, the separator 6 releases the plant material 4 and / or the fungus which mix with the substrate. 3. It is the association between water, plant matter or fungus, substrate and favorable temperature that allows germination to begin.

As illustrated in Figure 5, it is possible through the use of a dehydrated substrate to associate the latter directly with the plant material. The plant material is then fixed on the dehydrated substrate using a water-soluble organic adhesive, which is preferably a starch-based adhesive.

The invention thus makes it possible to easily promote the development of biodiversity, in particular by allowing the use of local seeds or of honey plants favorable to pollinating insects. The Applicant was also able to demonstrate that the presence of the separator 6 enabled the vegetation support according to the invention to be suitable for several uses, for example according to the seasons. Indeed, as illustrated in Figures 1, 9, 10, 11 and 12, the support can take the form of a conventional seat or ornamental cushion.

Thus, the vegetation support can be used for a first period as a conventional cushion, for example on a terrace or indoors. Then, at the discretion of the user or after the summer season ends, the support can be watered by seasonal rains or by the user and thus allow the growth of plant matter or fungi. It is then suitable for a second application (aesthetic, food, medicinal, etc.). The greening of small areas among individuals is today an important issue in terms of restoring urban biodiversity. In addition, the invention makes it possible to improve the air quality to a certain extent when it is placed inside a dwelling thanks to the plant / substrate / microorganism complex which catalyzes certain compounds deemed harmful to health. .

As illustrated in Figures 1 and 3, the invention by its shape and its ability to contain the substrate in all positions, can be used indoors and outdoors.

The form of the vegetation support according to the invention is characterized in that its height / width ratio is between 3: 1 and 1: 500, preferably between 1: 1 and 1: 50.

The height of the vegetation support 1 according to the invention is preferably greater than 5 mm and its width is preferably greater than 50mm. Even more preferably, its height is between 10 mm and 300 mm and its width is between 30 mm and 500 mm.

The support according to the invention is advantageously in the form of a flat cushion, a sphere or a polyhedron such as a cube, a prism or a pyramid.

Advantageously, the vegetation support 1 can, depending on the substrate used, change volume when it is activated.

Advantageously, the vegetation support 1 according to the invention is used for the growth of plant materials and / or fungi.

According to another advantageous embodiment of the invention, the vegetation support can be used, if it contains a fluid substrate, as an indoor or outdoor ornamental object, preferably a seat support, more preferably a cushion. Indeed, by its lightness, its flexibility, and its shape, the vegetation support can be used as an ornamental object of interior or exterior, preferably when the refill present in the envelope has not been previously activated.

Preferably, as illustrated in FIGS. 3, 4 and 12, the vegetation support also includes a mechanical opening and closing system 7.

The mechanical opening and closing system 7 is preferably chosen from a lace closure, a zipper or zipper, a clip closure or a zipper.

The mechanical opening and closing system 7 can be located at different locations on the support 1, preferably chosen from, the joint between the two parts of the casing 2, the upper part 22 and / or the lower part 21.

Said system 7 allows the normal use thereof or in the event of premature death of plants or fungi, to change the content of the support.

For example, it becomes possible, thanks to the mechanical opening and closing system 7, to reinsert a refill of substrate 3 and / or plant material 4. This system 7 also allows the user to personalize the mixture ( substrate, plant material and / or mushroom) that it wishes to integrate into the envelope 2.

A refill according to the invention designates a mixture of substrate and / or a plant material or a fungus inserting or extracting via the mechanical opening and closing system 7 present on the support. revegetation 1.

Advantageously, said refill may be a dehydrated substrate wafer to which plant material is integrated.

Said refill can also be surrounded by a membrane which is a water-soluble coating sheet, a water-soluble film or a biodegradable fabric.

Advantageously, the use of refill makes the support reusable and durable. The system can thus be kept for several years and allow the development of many plants and / or fungi.

The invention also relates to a water-soluble pocket 8 comprising a plant material 4 for support 1 according to the invention.

The Applicant was able to demonstrate that it could be particularly advantageous to change only said pocket 8 when germination is defective or when the user wishes, before watering for example, to change the plant material or the fungi that he wants to grow.

The last object of the invention is the use of a support 1 according to the invention, for the growth of a plant material 4 and / or of a fungus.

As illustrated in Figures 2, 4, and 8, the various elements of the support according to the invention allow, after watering, the growth of the plant material or the fungus.

This use allows the growth of one or more plant materials or fungi simultaneously, separately or spread over time.

Thus, the support 1 according to the invention can find different applications over time.
