Description
POT DE CULTURE POUR SUB-IRRIGATION ET POT DANS LEQUEL IL EST EMBOITE POUR LA VENTE D'UNE PLANTE.CROP POT FOR SUB-IRRIGATION AND POT IN WHICH IT IS PACKED FOR THE SALE OF A PLANT.
L'invention se rapporte aux pots en matière plastioue destinés à la culture d'une plante et, plus particulièrement, à ceux qui sont destinés à permettre d'utiliser la technique dite de "sub-irrigation".The invention relates to pots made of plastic material intended for the cultivation of a plant and, more particularly, to those which are intended to allow the use of the so-called "sub-irrigation" technique.
Cette technique consiste à poser le pot contenant la plante dans une sorte de bassin qui peut très vite se remplir d'une eau chargée de solutions nutritives, mouillant aussi la motte dans laquelle'la plante est enracinée.This technique consists in placing the pot containing the plant in a sort of basin which can quickly fill with water loaded with nutritive solutions, also wetting the root ball in which the plant is rooted.
On constate que lors de la vidange, elle-même rapide, du pot, laquelle s'effectue à travers des orifices pratiqués dans le fond du pot, muni de pieds pour le surélever, l'eau ne s'étale pas à la surface du fond, mais a tendance à former des boules. Ceci est notamment dû au fait que le pot est réalisé en une matière imperméable relativement cireuse, le plus souvent en polypropylène. Il en résulte, du fait de la tension superficielle, qu'une partie de l'eau reste sur le fond du pot, entre les orifices, sur une certaine épaisseur. En outre, l'écoulement ne se fait pas entre le fond du bassin et le dessous du pot. Le bas de la motte restant ainsi mouillé en permanence, cela provoque la pourriture des racines. It is noted that during the emptying, itself rapid, of the pot, which is carried out through orifices made in the bottom of the pot, provided with feet for raising it, the water does not spread on the surface of the melts, but tends to form balls. This is in particular due to the fact that the pot is made of a relatively waxy waterproof material, most often polypropylene. As a result, due to the surface tension, part of the water remains on the bottom of the pot, between the orifices, to a certain thickness. In addition, the flow does not take place between the bottom of the basin and the bottom of the pot. The bottom of the root ball thus remaining permanently wet, this causes root rot.
Un premier objet de l'invention est la réalisation d'un pot exempt de cet inconvénient.A first object of the invention is the production of a pot free from this drawback.
Suivant l'invention, ce résultat est atteint en donnant au fond du pot de culture une force conique à concavité dirigée vers l'extérieur et en remplaçant les orifices d'écoulement habituellement ménagés dans le fond du pot par des ouvertures verticales ménagées dans la portion inférieure de la paroi latérale dudit pot.According to the invention, this result is achieved by giving the bottom of the culture pot a conical force with a concavity directed towards the outside and by replacing the flow orifices usually formed in the bottom of the pot with vertical openings formed in the portion lower side wall of said pot.
Dans un mode d'exécution préféré, la portion inférieure de la paroi latérale du pot dans laquelle sont ménagées lesdites ouvertures est suffisamment surélever, par rapport au plan de sustentation du pot, pour éviter que l'eau qui stagne dans le fond du bassin après la vidange puisse remonter par capillarité jusqu'aux ouvertures.In a preferred embodiment, the lower portion of the side wall of the pot in which said openings are made is raised enough, relative to the plane of lift of the pot, to prevent the water which stagnates in the bottom of the basin after the drain can go up by capillary action to the openings.
Un deuxième objet de l'invention est la réalisation d'un pot destiné à la vente, qui permette lui-même un bon écoulement de l'eau, et qui présente des dimensions extérieures conformes à la normalisation imposée par les emballages d'expédition, et un aspect extérieur conforme aux souhaits des clients.A second object of the invention is the production of a pot intended for sale, which itself allows good flow of water, and which has external dimensions in accordance with the standard imposed by shipping packaging, and an external appearance in accordance with the wishes of the customers.
Actuellement, il est en pratiaue exclu de recouvrir le pot de culture d'un cache-pot classique, qui n'a pas les dimensions normalisées et surtout, ne permet pas l'évacuation de l'eau qui a été introduite lors du dernier arrosage pratiqué au moment de l'expédition. On préfère donc le plus souvent expédier la plante dans le pot de culture, ce qui conduit à conférer à celui-ci un aspect extérieur agréable, notamment coloré. L'inconvénient qui en résulte est que les substances nutritives contenues dans l'eau d'irrigation se déposent sur le tiers inférieur de la surface latérale du pot et nuisent à son aspect.Currently, it is in practice excluded to cover the growing pot with a classic plant pot, which does not have standardized dimensions and above all, does not allow the evacuation of the water which was introduced during the last watering practiced at the time of shipment. It is therefore most often preferred to send the plant to the culture pot, which leads to giving it a pleasant external appearance, in particular colored. The resulting disadvantage is that the nutrients contained in the irrigation water settle on the lower third of the side surface of the pot and affect its appearance.
Selon l'invention, ces inconvénients des solutions connues sont supprimés en emboitant un pot de culture, qui pourra ne pas avoir un aspect extérieur soigné, dans un pot de vente de dimensions normalisées lui-même muni d'ouvertures d'évacuation de l'eau.According to the invention, these drawbacks of known solutions are eliminated by fitting a culture pot, which may not have a neat external appearance, in a sales pot of standardized dimensions itself provided with evacuation openings of the water.
Les diverses particularités de l'invention apparaitront clairement à la lumière de la description ci-après.The various features of the invention will become apparent in the light of the description below.

tion préféré de l'invention
La figure 2 est une vue, à échelle plus grande que
celle de la figure 1, de la portion inférieure de la

La figure 3 est une vue partielle en élévation à la
même échelle que celle de la figure 2, qui montre
l'une des ouvertures.In the attached drawing
Figure 1 is a partial view in longitudi section
nale of a culture pot conforming to a mode of execution
preferred invention
FIG. 2 is a view, on a larger scale than
that of FIG. 1, of the lower portion of the
side wall of the pot, fitted with drainage openings
tion of water; and
Figure 3 is a partial elevational view at
same scale as that of figure 2, which shows
one of the openings.
A la figure 1, on a représenté un pot de culture tronconique 1 à fond conique, conformé et dimensionné pour s'emboîter exactement dans un pot de vente 2 à fond plan. Le pot 1 est, par exemple, réalisé en polypropylène noir et le pot 2, en polypropylène coloré dans la masse, et avec des dimensions extérieurès conformes aux normes imposées par les emballages d'expédition.In Figure 1, there is shown a frustoconical culture pot 1 with a conical bottom, shaped and dimensioned to fit exactly into a sales pot 2 with a flat bottom. The pot 1 is, for example, made of black polypropylene and the pot 2, of polypropylene colored in the mass, and with external dimensions in accordance with the standards imposed by the shipping packaging.
La paroi latérale du pot 1 est prolongée par une nervure circulaire 10 ayant, à titre d'exemple, 1,9 mm de hauteur pour un pot ayant une hauteur totale de 118,82 mm.The side wall of the pot 1 is extended by a circular rib 10 having, for example, 1.9 mm in height for a pot having a total height of 118.82 mm.
Le fond 11 est conique, avec un angle (a, figure 2) à la base du cône de 7 . The bottom 11 is conical, with an angle (a, figure 2) at the base of the cone of 7.
Des ouvertures, telles que 12, sont ménagées dans des plans radiaux de symétrie du pot, avantageusement distribués uniformément sur sa paroi latérale, et qui sont, à titre d'exemple, au nombre de 9. On voit à la figure 3 que ces ouvertures débouchent à la base ce la nervure 10 et ont, dans l'exemple décrit, une forme générale trapézoldale avec un arrondi à leur sommet. A titre d'exemple, leur largeur à la grande base ouverte du trapèze est de 3,3 mm et leur hauteur totale (h, figure 2) est de 12,4 mm.Openings, such as 12, are formed in radial planes of symmetry of the pot, advantageously distributed uniformly on its side wall, and which are, for example, 9 in number. It can be seen in FIG. 3 that these openings open at the base that the rib 10 and have, in the example described, a general trapezoidal shape with a rounded at their top. For example, their width at the large open base of the trapezoid is 3.3 mm and their total height (h, Figure 2) is 12.4 mm.
Le fond 11 n'est muni d'aucune ouverture.The bottom 11 is not provided with any opening.
I1 résulte de l'agencement décrit que l'eau excédentaire de la motte s'écoule au moment de la vidange, le long de la surface intérieure conique du fond 11 et à travers la portion des ouvertures en communication avec la périphérie de cette surface. I1 results from the arrangement described that the excess water from the root ball flows at the time of emptying, along the conical inner surface of the bottom 11 and through the portion of the openings in communication with the periphery of this surface.
Le point bas de ladite portion des ouvertures se trouvant, dans l'exemple décrit, à 2,48 mm de la base de la nervure,
I'eau qui stagne dans le fond du bassin ne peut remonter par capillarité jusqu'à ladite portion pour pénétrer dans la motte.The low point of said portion of the openings being, in the example described, at 2.48 mm from the base of the rib,
The water which stagnates in the bottom of the basin cannot go up by capillary action to said portion to penetrate into the root ball.
Le pot ae vente 2 aura avantageusement un fond plat surélevé par une nervure circulaire (20, figure 1) et sera lui-même muni d'ouvertures (non représentées)/ avantageusement disposées sur la portion inférieure de sa paroi latérale.The ae sale pot 2 will advantageously have a flat bottom raised by a circular rib (20, FIG. 1) and will itself be provided with openings (not shown) / advantageously arranged on the lower portion of its side wall.
Il permettra ainsi l'évacuation de l'eau provenant du dernier arrosage de la motte avant expédition.It will thus allow the evacuation of water from the last watering of the root ball before shipment.
I1 va de soi que des modifications, tant dans la forme que dans les dimensions, des pots décrits et représentés, pourront etre apportées par llbomme du métier sans s'écarter de l'esprit de l'invention. It goes without saying that modifications, both in shape and in dimensions, of the pots described and shown, may be made by one skilled in the art without departing from the spirit of the invention.
