Abstract
Description
La présente invention a pour objet un conteneur pour la culture de plants et son procédé de fabrication. The present invention relates to a container for growing plants and its manufacturing process.
On connaît actuellement différents types de conteneurs ou de pots destinés à la culture et l'emballage de jeunes plantes ou plants avant leur mise en place définitive dans la terre, lesdits conteneurs ou pots devant offrir les conditions d'une croissance optimum pendant toute la durée de la culture. There are currently known different types of containers or pots intended for the cultivation and packaging of young plants or seedlings before their final placement in the ground, said containers or pots having to offer the conditions for optimum growth throughout the duration of the culture.
Ces pots sont généralement fabriqués en une matière plastique comme le PVC, le polyéthylène ou le polypropylène, en fibres de bois ou de tourbe compressées, en carton pressé, en métal ou autre. These pots are generally made of a plastic material such as PVC, polyethylene or polypropylene, compressed wood or peat fibers, pressed cardboard, metal or other.
Toutefois dans le cas d'un pot en matière plastique les racines du plant ne peuvent pas, durant leur culture, pénétrer dans les parois desdits pots, ce qui cause des problèmes d'enroulement et d'étouffement desdites racines appelés "chignonage"; de plus il est nécessaire de dépoter le plant avant sa mise en terre ou son repiquage dans un pot plus grand, et de le dépoter et le rempoter plusieurs fois pendant la durée de la culture, inconvénient auquel s'ajoute celui inhérent au fait que le recyclage des pots est relativement coûteux. However, in the case of a plastic pot, the roots of the plant cannot, during their cultivation, penetrate into the walls of said pots, which causes problems of winding and suffocation of said roots called "chignonage"; moreover it is necessary to deposit the plant before its planting or its transplanting in a larger pot, and to deposit it and repot it several times during the duration of the culture, disadvantage to which is added that inherent to the fact that the recycling pots is relatively expensive.
En ce qui concerne les pots en carton , en bois ou en tourbe, leur faible résistance mécanique, d'une part à la poussée des racines des plants et d'autre part aux chocs durant leur manutention et leur transport, ne permet pas la réalisation de pots de grande contenance, par exemple supérieure ou égale à deux litres, ce qui réduit les chances de survie des plants lors de leur mise en terre; de plus ils ne permettent pas une durée de culture supérieure à trois mois environ. Regarding cardboard, wooden or peat pots, their low mechanical resistance, on the one hand to the push of the roots of the plants and on the other hand to impacts during their handling and transport, does not allow the realization pots with a large capacity, for example greater than or equal to two liters, which reduces the chances of survival of the plants when they are planted; moreover, they do not allow a culture period of more than about three months.
Enfin les conteneurs métalliques comportant des parois cannelées rouillent sous l'action de l'eau et des engrais et leur paroi est un mauvais isolant thermique. Finally, metal containers with fluted walls rust under the action of water and fertilizers and their walls are a poor thermal insulator.
La présente invention a pour but de remédier à ces divers inconvénients en proposant un conteneur qui présente une pénétrabilité racinaire relativement importante, une résistance mécanique accrue, une bonne isolation thermique des racines du végétal, et permet d'éviter les opérations de dépotage et de contrôle de la motte de terre entourant les racines du plant, permettant un gain de temps et facilitant les opérations de plantation, ledit conteneur se dégradant en outre biologiquement en contribuant à la nutrition du végétal, sans laisser de déchet dans l'environnement. The object of the present invention is to remedy these various drawbacks by proposing a container which has relatively high root penetration, increased mechanical resistance, good thermal insulation of the roots of the plant, and makes it possible to avoid unloading and control operations. clod of earth surrounding the roots of the plant, saving time and facilitating planting operations, said container further degrading biologically contributing to the nutrition of the plant, without leaving any waste in the environment.
Le conteneur selon l'invention se caractérise essentiellement en ce qu'ii est réalisé en un matériau composé de fibres textiles naturelles solidarisées entre elles au moyen d'un liant constitué d'un matériau thermofusible ou thermosoluble. The container according to the invention is essentially characterized in that it is made of a material composed of natural textile fibers joined together by means of a binder consisting of a hot-melt or heat-soluble material.
Le procédé de fabrication d'un tel matériau consiste à mélanger plusieurs fibres textiles naturelles telles que du lin, de la laine, du coton ou autres, dans des proportions bien définies, en les introduisant sous forme déchiquetée à l'entrée d'un mélangeur, tandis qu'à une autre entrée dudit mélangeur on introduit, sous la même forme, en une proportion déterminée en fonction de la composition voulue, un liant destiné à être incorporé auxdites fibres naturelles de façon homogène, le mélange étant ensuite porté dans une enceinte en vue de faire fondre ou de dissoudre le liant de manière à souder les différentes fibres naturelles entre elles. Le matériau obtenu est préférentiellement mis, à la sortie de l'enceinte, en forme de nappe qui est ensuite prédécoupée et emboutie à l'aide de moyens connus, comme par exemple une presse à chaud. The process for manufacturing such a material consists in mixing several natural textile fibers such as linen, wool, cotton or the like, in well defined proportions, by introducing them in shredded form at the inlet of a blender. , while at another inlet of said mixer is introduced, in the same form, in a proportion determined according to the desired composition, a binder intended to be incorporated into said natural fibers in a homogeneous manner, the mixture then being carried in an enclosure with a view to melting or dissolving the binder so as to weld the various natural fibers together. The material obtained is preferably placed, at the outlet of the enclosure, in the form of a sheet which is then precut and stamped using known means, such as for example a hot press.
Conformément à l'invention, le liant mis en oeuvre peut être un liant thermofusible, comme par exemple le polypropylène, auquel cas l'enceinte est un four qui porte le mélange à une température contrôlée en vue de faire fondre le polypropylène et souder les fibres entre elles. According to the invention, the binder used can be a hot-melt binder, such as for example polypropylene, in which case the enclosure is an oven which brings the mixture to a controlled temperature in order to melt the polypropylene and weld the fibers. between them.
Le liant utilisé peut également être un liant hydrosoluble à une certaine température, préférentiellement supérieure à la tempéraure ambiante, comme par exemple l'amidon ou un alcool polyvinylique, auquel cas l'enceinte est un bain ou autre moyen d'imprégnation. The binder used can also be a water-soluble binder at a certain temperature, preferably higher than the ambient temperature, such as for example starch or a polyvinyl alcohol, in which case the enclosure is a bath or other impregnation means.
Toujours conformément à l'invention d'autres matières premières naturelles, comme par exemple des déchets de papier, de carton, de bois, de tourbe, ou autres, peuvent être mélangées avec les fibres textiles dans une proportion déterminée de manière que la quantité de fibres textiles présente dans le mélange lui assure une résistance mécanique suffisante aux chocs et à la poussée des racines du plant qui sera introduit dans le conteneur. Still in accordance with the invention, other natural raw materials, such as for example waste paper, cardboard, wood, peat, or the like, can be mixed with the textile fibers in a proportion determined so that the amount of textile fibers present in the mixture provides it with sufficient mechanical resistance to impact and to the push of the roots of the plant which will be introduced into the container.
La nappe du matériau mis en oeuvre pour la réalisation de conteneurs selon l'invention devra être suffisamment rigide pour permettre de faire un conteneur qui tienne debout, son épaisseur pouvant varier en fonction de sa résistance mécanique et de la contenance du pot à fabriquer. The sheet of material used for the production of containers according to the invention must be rigid enough to allow a container to stand up, its thickness being able to vary according to its mechanical strength and the capacity of the pot to be manufactured.
A titre d'exemple d'une composition convenant à la fabrication de conteneurs pour plants d'une capacité de deux litres environ, on peut citer la suivante:
- laine 25 E
- coton 60 9
- lin 10 z
- polypropylène 5 %
Un conteneur réalisé à partir de cette composition peut être, par passage dans des bains, enduit de substances chimiques comme par exemple des engrais ou des produits phytosanitaires, ou encore de produits bactériologiques, de germes de microorganismes sélectionnés tels que des champignons, des bactéries, des protozoaires, ou autres.By way of example of a composition suitable for the manufacture of containers for plants with a capacity of approximately two liters, the following may be mentioned:
- wool 25 E
- cotton 60 9
- linen 10 z
- 5% polypropylene
A container produced from this composition can be, by passage through baths, coated with chemical substances such as, for example, fertilizers or phytosanitary products, or also bacteriological products, germs of selected microorganisms such as fungi, bacteria, protozoa, or the like.
Les conteneurs selon l'invention peuvent également être teintés à l'aide de colorants non toxiqueSpour les végétaux, et de préférence biodégradables. The containers according to the invention can also be tinted using non-toxic dyes for plants, and preferably biodegradable.
Il va de soi que la présente invention ne saurait être limitée à la description qui précède et qui est susceptible de subir un certain nombre de modifications sans pour autant sortir du cadre de l'invention. It goes without saying that the present invention cannot be limited to the above description and which is liable to undergo a certain number of modifications without departing from the scope of the invention.
