An opening (1d) on an upper part of a water compartment fills dimensioned base and lateral walls of the compartment so that water exerts a permanent natural pressure on ends (4a) of the core. Base of an outer wall of the container has a discharge opening (1e) closed by a stopper.

Description

BAC A RESERVE D'EAU POUR PLANTES DESCRIPTIONSTORAGE BOX FOR PLANTS DESCRIPTION

DOMAINE DE L'INVENTION L'invention concerne un bac à réserve d'eau pour plantes du genre constitué d'un récipient monobloc comprenant généralement: a) une double paroi dont la paroi externe délimite le bac proprement dit, dont la paroi interne délimite un compartiment apte à recevoir un substrat et dont l'espace compris entre lesdites deux parois constitue un autre compartiment apte à recevoir de l'eau; b) au moins une ouverture, aménagée sur le fond de la paroi interne du bac, apte à laisser passer l'eau entre lesdits deux compartiments. FIELD OF THE INVENTION The invention relates to a water tank for plants of the type consisting of a one-piece container generally comprising: a) a double wall whose outer wall delimits the tank itself, whose inner wall defines a compartment adapted to receive a substrate and the space between said two walls is another compartment adapted to receive water; b) at least one opening, arranged on the bottom of the inner wall of the tray, adapted to allow water to pass between said two compartments.

ARRIERE PLAN TECHNOLOGIQUEBACKGROUND TECHNOLOGY

Les bacs connus du genre en question, généralement à usage urbain, sont alimentés en déversant de l'eau au dessus du substrat. The bins known of the kind in question, generally for urban use, are fed by pouring water over the substrate.

Ils comportent, sur le fond du compartiment à substrat, une pluralité d'ouvertures aptes à laisser passer l'eau déversée et, sur la partie latérale de la paroi externe du bac, au moins une ouverture apte à laisser passer le trop plein. They comprise, on the bottom of the substrate compartment, a plurality of openings adapted to let the spilled water and, on the lateral portion of the outer wall of the tray, at least one opening adapted to let the overflow.

Ils présentent les principaux inconvénients suivants: - l'alimentation en eau par le dessus du substrat est à l'origine d'un manquement d'arrosage principalement en été lorsque celui-ci présente une croûte à sa surface; les ouvertures de passage entre les deux compartiments s'obstruent dans le temps; They have the following main drawbacks: - The water supply from above the substrate is the cause of a failure of watering mainly in summer when it has a crust on its surface; the passage openings between the two compartments become clogged in time;

Claims

- The water supply is of low capacity (use of the water supply in the bottom of the container) causing a higher filling frequency. SUMMARY OF THE INVENTION The invention aims to provide a tray of the kind in question to implement a novel and original solution able to eliminate the aforementioned drawbacks. It relates for this purpose, a tank water reserve which is characterized in that it comprises, in combination: a) on the bottom of the inner wall of the container, at least one pair of openings able to pass a capillary wick whose ends plunge into the water and whose loop extends into the substrate; b) on the upper part of the water compartment, at least one aperture adapted to fill the bottom and the side walls thereof which are dimensioned so that the water can exert a permanent natural pressure on the ends of the wick. Water is therefore introduced directly into the water reserve and no longer onto the substrate. The capillary wicks are defined to diffuse only the quantity of water necessary. According to particular features of the invention: - the bottom of the substrate compartment comprises a pipe, closable by means of a plug, able to evacuate to the outside the overflow of rain water; the bottom of the outer wall of the container has a drain opening closable by means of a plug for evacuating water for cleaning the tank or the change of the plant; - The upper side of the outer wall of the container comprises at least two recessed portions, opposite, able to act as handles for easy handling. PRESENTATION OF THE FIGURES The characteristics and advantages of the invention will appear more clearly on reading the detailed description which follows of at least one preferred embodiment thereof given by way of non-limiting example and shown in the drawings. attached. In these drawings: - Figure 1 shows a longitudinal sectional view of the water tank according to the invention; - Figure 2 shows a cross sectional view of the body of said tray. DETAILED DESCRIPTION OF THE INVENTION The plant water storage tank, shown in the figures, consists of a one-piece container (1), generally made of plastic material and obtained by rotomoulding, of the type comprising: a) a double wall whose outer wall (1a) delimits the tank itself, whose inner wall (1b) delimits a compartment adapted to receive a substrate (2) and whose space between said two walls constitutes another compartment adapted to receive water (3); b) at least one opening (1c), arranged on the bottom of the inner wall (1b) of the tray, adapted to allow water to pass between said two compartments. It comprises, in combination: a) on the bottom of the inner wall (1b) of the container (1), at least one pair of openings (1c) able to pass a capillary wick (4) whose ends (4a) dive into the water (3) and whose loop (4b) extends into the substrate (2); b) on the upper part of the water compartment, at least one opening (1d) capable of filling the bottom and the side walls thereof which are sized so that the water (3) can exert a permanent natural pressure on the ends (4a) of the wick (4). The bottom of the substrate compartment may comprise a pipe (1g), closable by means of a plug, able to evacuate outward overflow of rainwater. The bottom of the outer wall (la) of the container (1) may comprise a drain opening (1) closable by means of a plug. The upper lateral part of the outer wall (la) of the container (1) may comprise at least two recessed portions (1f), opposite, able to act as handles. The filling opening (1d) of the water compartment can be closed by means of a plug provided with a vent. The lateral part of the outer wall (la) of the container (1) may comprise at least one opening (1h), closable by means of a plug, adapted to let the overflow of the water compartment. When the tank is used according to the principle of the invention (supply by the water supply), the pipe (1g) is open and the opening (1h) closed. When the tray is used according to the principle of the prior art (feeding by the substrate), the pipe (1g) is closed and the opening (1h) open. The lateral part of the outer wall (la) of the container (1) may comprise threaded inserts (5) adapted to ensure its attachment to any type of support such as for example barriers, facades or walls. The locks may be made of biodegradable natural fibers. The material used may be polyethylene. Concerning the water reserve: - in the bins fed by the substrate, its capacity is about 5 liters; - In the bins fed by the water supply, its capacity can reach 12 liters. Of course, the invention is not limited to the embodiments described and shown for which there may be other variants, in particular in: - the nature, shape and dimensions of the tray and compartments that compose it; - the technique of manufacturing the tank - the nature, the dimensions and the number of capillary wicks; - the type of medium with which it is associated; - the type of urban or domestic application for which it is intended; without departing from the scope of the invention.
