Abstract

The flower pot has a frusto-conical body (1), the lower edge of which has formed in it. A separate base (2) is fitted to the main body and this has large drainage openings formed around the annular wall. The upper edge of the base is smaller than the lower edge of the body and a set of radially extending lugs (203) extend into the slots. When the plant is pulled out of the pot, the base disengages itself from the slots and is pulled up through the body of the pot with the plant so as not to disrupt the roots.

Description

POT DESTINE A LA CULTURE DE VEGETAUX.POT FOR GROWING PLANTS.

La présente invention se rapporte aux pots destinés à la culture de plantes dans une motte de terre contenue dans le pot et, en particulier, en serre.The present invention relates to pots intended for growing plants in a clod of earth contained in the pot and, in particular, in a greenhouse.

Ces pots comportent le plus souvent une partie ajourée (fond, et de préférence base du corps), munie de fenêtres qui permettent le passage des racines de la plante.These pots most often have an openwork part (bottom, and preferably base of the body), provided with windows which allow the passage of the roots of the plant.

Quand on enlève la plante du pot, soit pour la placer dans un pot de plus grande taille, soit parce que la culture "hors sol" est terminée, celui-ci est détérioré par l'effet d'arrachement dû au passage des racines dans les fenêtres.When the plant is removed from the pot, either to place it in a larger pot, or because the "above-ground" cultivation is finished, it is deteriorated by the pulling effect due to the passage of the roots in the Windows.

Suivant l'invention, la partie ajourée du pot est constituée par une pièce amovible ayant un bord extrême libre, dont le diamètre est inférieur à celui de la base du reste du corps, et ledit bord extérieur de la pièce amovible est muni de moyens d'accrochage temporaire au reste du corps, ces moyens d'accrochage étant agencés pour que l'enlèvement de la plante provoque le décrochage de ladite pièce amovible et son passage à l'intérieur du reste du corps.According to the invention, the perforated part of the pot consists of a removable part having an extreme free edge, the diameter of which is less than that of the base of the rest of the body, and said outer edge of the removable part is provided with means of 'temporary attachment to the rest of the body, these attachment means being arranged so that the removal of the plant causes the detachment of said removable part and its passage inside the rest of the body.

Grâce à cet artifice, le pot peut être réutilisé, seule ladite partie amovible devant être remplacée, ce qui entraîne une économie notable. Thanks to this device, the pot can be reused, only said removable part having to be replaced, which leads to a significant saving.

Selon un mode d'exécution préféré, les moyens d'accrochage comportent des languettes- distribuées sur la périphérie du bord extérieur libre de la partie amovible et agencées pour venir s'engager dans des fentes ménagées à la base du reste du corps, tandis que ce dernier est muni, dans sa portion située au-dessus des fentes, de rainures disposées suivant des génératrices et agencées pour servir au guidage desdites languettes lors de la mise en place de la pièce amovible, jusqu'à l'engagement des languettes dans les fentes.According to a preferred embodiment, the hooking means comprise tongues- distributed on the periphery of the free outer edge of the removable part and arranged to engage in slots made at the base of the rest of the body, while the latter is provided, in its portion located above the slots, with grooves arranged along generators and arranged to serve for guiding said tongues during the positioning of the removable part, until the engagement of the tongues in the slots.

Avantageusement, ladite partie amovible est constituée en une matière bio-dégradable apte à être détruite au bout d'un temps correspondant sensiblement à la durée normale de culture de la plante dans le pot.Advantageously, said removable part is made of a bio-degradable material capable of being destroyed after a time corresponding substantially to the normal duration of culture of the plant in the pot.

Suivant une autre particularité de l'invention, ladite partie amovible du pot est munie d'une pièce centrale tronconique ajourée, dont la grande base repose sur le fond.According to another feature of the invention, said removable part of the pot is provided with a perforated frustoconical central part, the large base of which rests on the bottom.

Cette pièce tronconique, dans laquelle la motte ne pénètre pas, facilite la pénétration des racines et leur oxygénation.This frustoconical part, in which the root ball does not penetrate, facilitates the penetration of the roots and their oxygenation.

L'invention sera mieux comprise à l'aide de la description ci-après.The invention will be better understood with the aid of the description below.

tapered openwork; and
Figure 4 is a detail view of the lower edge of the
pot of figures 1 and 2.

Le pot représenté à la figure 1 comprend un élément principal de corps tronconique 1, muni à sa partie supérieure, d'une collerette 101 et une partie amovible 2 composée d'un fond 201 et d'une portion inférieure de corps tronconique 202.The pot shown in FIG. 1 comprises a main element of frustoconical body 1, provided at its upper part with a flange 101 and a removable part 2 composed of a bottom 201 and a lower portion of frustoconical body 202.

Comme on le voit à la figure 2, le fond 201 est ajouré de manière connue en soi, tandis que le bord extérieur libre de la portion de corps 202 elle-même ajourée, est muni de languettes, telles que 203, 204, régulièrement réparties par couple de deux languettes diamétralement opposées, sur sa périphérie. A titre d'exemple non limitatif, ces languettes sont au nombre de six. L'élément du corps 1 est muni à sa base, de fentes telles que 104 au nombre et disposition correspondants.As seen in Figure 2, the bottom 201 is perforated in a manner known per se, while the free outer edge of the body portion 202 itself perforated, is provided with tabs, such as 203, 204, regularly distributed by pair of two diametrically opposite tongues, on its periphery. By way of nonlimiting example, these tongues are six in number. The element of the body 1 is provided at its base with slots such as 104 with the corresponding number and arrangement.

On voit que le diamètre du bord extérieur libre de la portion de corps 202 est légèrement inférieur (par exemple de cinq pour cent) au diamètre externe de la base de l'élément principal 1, la différence correspondant sensiblement à deux fois la dimension radiale d'une languette. Ces languettes, lors de l'introduction de la portion de corps amovible 2 dans l'élément principal de corps 1, viennent s'engager à la base de rainures correspondantes, telles que 102, 103 ménagées dans la paroi interne de l'élément 1 suivant les portions de génératrices de celle-ci situées au-dessus des fentes et sont guidées par celle-ci, jusqu'à une position voisine de la base inférieure de l'élément 1, où elles se trouvent engagées dans les fentes 104, de façon à obtenir u vowrcuillage Les rainures et l'élément 1 lui-même ont une profondeur (respectivement, une épaisseur) croissante de leur partie supérieure à leur base.It can be seen that the diameter of the free outer edge of the body portion 202 is slightly smaller (for example by five percent) than the outer diameter of the base of the main element 1, the difference corresponding substantially to twice the radial dimension d 'a tongue. These tabs, during the introduction of the removable body portion 2 into the main body element 1, engage at the base of corresponding grooves, such as 102, 103 formed in the internal wall of the element 1 along the portions of generators thereof situated above and are guided by the slots, to a position close to the lower base of the element 1, where they are engaged in the slots 104, so as to obtain u vowrcuillage The grooves and the element 1 itself have a depth (respectively, a thickness) increasing from their upper part to their base.

Lorsqu'on enlève la plante en tirant sur sa tige, la partie amovible 2 se décroche et passe, avec la plante, à l'intérieur de l'élément principal de corps 1. Ce dernier est réutilisable en le munissant d'une nouvelle partie amovible.When the plant is removed by pulling on its stem, the removable part 2 comes off and passes, with the plant, inside the main body element 1. The latter is reusable by providing it with a new part removable.

Avantageusement, l'élément 1 est en matière thermoplastique souple, tandis que la partie amovible 2 est, soit constituée de la même matière, soit, de préférence, constituée en un carton ou autre matière biodégradable, apte à être détruite en deux mois par exemple par les bactéries contenues dans la motte.Advantageously, the element 1 is made of flexible thermoplastic material, while the removable part 2 is either made of the same material, or, preferably, made of a cardboard or other biodegradable material, capable of being destroyed in two months for example by bacteria in the root ball.

On pourrait envisager de ne faire comporter à la partie amovible 2 que le fond 201, qui serait alors lui-même mùni de languettes telles que décrites venant coopérer avec les rainures de l'élément principal de corps 1.It could be envisaged to make the removable part 2 only comprise the bottom 201, which would then itself be provided with tongues as described coming to cooperate with the grooves of the main body element 1.

Dans la variante de la figure 3, le fond est muni en son centre, d'une pièce tronconique ajourée 205 dont la grande base (complètement ouverte) est solidaire du fond et la petite base, sensiblement située dans le plan du bord supérieur libre de la partie amovible 2.In the variant of FIG. 3, the bottom is provided at its center with an openwork frustoconical piece 205, the large base (completely open) of which is integral with the bottom and the small base, substantially situated in the plane of the free upper edge of the removable part 2.

Les racines de la plante ont normalement tendance à se développer latéralement en évitant, pour leur majeure partie, la partie centrale de la motte. La pièce 205, vide de terreau à l'intérieur, supprime cet inconvénient et permet, grâce à l'oxygénation qu'elle procure, le développement de racines centrales qui la traversent. Avantageusement, un tuyau (non figuré), fait communiquer l'intérieur de la pièce 205 avec l'extérieur du pont.The roots of the plant normally tend to develop laterally, for the most part avoiding the central part of the root ball. The part 205, empty of soil inside, eliminates this drawback and allows, thanks to the oxygenation which it provides, the development of central roots which pass through it. Advantageously, a pipe (not shown) communicates the interior of the room 205 with the exterior of the bridge.

I1 va de soi que la forme et les dimensions des pièces illustrées et la forme d'exécution des moyens d'accrochage, pourront varier, sans s'écarter de l'esprit de l'invention.  It goes without saying that the shape and dimensions of the parts illustrated and the embodiment of the attachment means may vary, without departing from the spirit of the invention.
