Description
CONTENEUR POUR LA CULTURE DE PLANTS ET SON PROCEDE DE FABRICATION. CONTAINER FOR GROWING PLANTS AND MANUFACTURING METHOD THEREOF.
La présente invention a pour oo-jet un conteneur pour la culture αe piants et son procédé αe fabrication. On connaît actuellement différents types de conteneurs ou αe pots destinés a ia culture et 1 emDaiiage αe "jeunes plantes ou plants avant leur mise en place définitive dans la terre, iesdits conteneurs ou pots devant offrir les conditions d'une croissance optimum pendant toute la durée de la culture.The present invention has for oo-jet a container for the cultivation of feet and its manufacturing process. There are currently known different types of containers or pots intended for cultivation and first packaging of "young plants or plants 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 polyétnylene ou le polypropylène, en fiores de DOIS OU de tourne compressées, en carton pressé, en métal ou autre. Toutefois dans le cas d un pot en matière plastique les racines au p ant ne peuvent pas, αurant leur culture, pénétrer dans les parois desdits pots, ce qui cause des problèmes d enroulement et d étouffement αesdites racines appelés ' cnignonage" ; 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. En ce qui concerne les pots en carton , en bois ou en tourrje, 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 αuree de culture supérieure à trois mois environ.These pots are generally made of a plastic material such as PVC, polyethylene or polypropylene, in flours of compressed DOIS or spins, in pressed cardboard, in metal or other. However in the case of a plastic pot the roots at the front can not, during their cultivation, penetrate the walls of said pots, which causes problems of winding and suffocation to said roots called "cnignonage"; moreover it it is necessary to plant the plant before planting it or transplanting it into a larger pot, and to plant it and repot it several times during the cultivation period, a disadvantage to which is added that inherent in the fact that recycling the pots is relatively expensive. As regards cardboard, wooden or tourrje pots, their low mechanical resistance, on the one hand to the pushing of the roots of the plants and on the other hand to impacts during their handling and transport, does not allow the production of 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 an αure growing 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 penetranilite racmaire relativement importante, une résistance mécanique accrue, une bonne isolation tnermique des racines du végétal, et permet d éviter les opérations αe dépotage et de contrôle de la motte de terre entourant les racines du plant, permettant un gain de temps et facilitant les opérations αe plantation, ledit conteneur se dégradant en outre bioiogiquement en contπr ant à la nutrition du végétal, sans laisser de déchet dans 1 'environnement. Le conteneur selon 1 ' invention se caractérise essentiellement en ce qu'il est réalisé en un matériau composé de fibres textiles naturelles solidarisées entre elles au moyen d'un liant constitué d un matériau thermofusible ou thermosoiuble. Le procède de faorication d un tel matériau consiste a mélanger plusieurs fibres textiles naturelles telles que du 1m, de la lame, 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 audit 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 1 enceinte, en forme de nappe qui est ensuite prédécoupée et emboutie à l'aide de moyens connus, comme par exemple une presse à chaud. 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. Le liant utilisé peut également être un liant hydrosolubie a une certaine température, préférentiellement supérieure à la tempéraure ambiante, comme par exemple
1 amidon ou un alcool polyvmylique, auquel cas l'enceinte est un bain ou autre moyen d imprégnation.The object of the present invention is to remedy these various drawbacks by proposing a container which has relatively high penetranility, increased mechanical resistance, good thermal insulation of the roots of the plant, and makes it possible to avoid the operations of stripping and controlling the clod of earth surrounding the roots of the plant, saving time and facilitating planting operations, said container further degrading bioiogically by contributing to the nutrition of the plant, without leaving any waste in the environment. 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. The process of making such a material consists in mixing several natural textile fibers such as 1m, strip, cotton or the like, in well defined proportions, by introducing them in shredded form at the inlet of a mixer, while that at another input to said mixer is introduced, in the same form, in a proportion determined as a function of 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 for to melt or dissolve the binder so as to weld the different natural fibers together. The material obtained is preferably placed, at the outlet of 1 enclosure, in the form of a sheet which is then precut and stamped using known means, such as for example a hot press. 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. The binder used can also be a water-soluble binder at a certain temperature, preferably higher than the ambient temperature, such as for example 1 starch or polyvinyl alcohol, in which case the enclosure is a bath or other means of impregnation.
Toujours conformément a l'invention d'autres matières premières naturelles, comme par exemple αes déchets de papier, de carton, de bois, de tourbe, ou autres, peuvent être mélangées avec ies fibres textiles dans une proportion déterminée de manière que la quantité de fmres 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 e 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 The textile fibers present in the mixture provide it with sufficient mechanical resistance to impact and to the pushing 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 1 ' invention αevra 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 faoπquer.The sheet of material used for the production of containers according to the invention should 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 shaped.
A titre α exemple d'une composition convenant à la faorication de conteneurs pour plants d'une capacité de deux litres environ, on peut citer la suivante:As an example of a composition suitable for making containers for plants with a capacity of approximately two liters, the following may be mentioned:
- lame 25 % - coton όû %
- blade 25% - cotton όû%
- polypropylène 5 %- 5% polypropylene
Un conteneur réalisé à partir de cette composition peut être, par passage dans des bains, enduit de suostances chimiques comme par exemple des engrais ou des proαuits phytosanitaires, ou encore de produits Dactéπologiques, de germes de microorganismes sélectionnés tels que des champignons, des bactéries, des protozoaires, ou autres. Les conteneurs selon 1 ' invention peuvent également être teintés à 1 • aide de colorants non toxique pour ies végétaux, et de préférence oiodégradables.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 even Dactéπologiques products, with germs of selected microorganisms such as fungi, bacteria, protozoa, or the like. The containers 1 according to the invention can also be tinted to 1 • Using non-toxic dyes ies plants, preferably oiodégradables.
