FR3024641A1 - INDEPENDENT TANK IN TERRACOTTA WITH INTEGRATED TANK FOR WATER SUPPLY OF PLANTS - Google Patents

Abstract

The invention relates to a device for ensuring the regular supply of plants in water autonomously and environmentally. It is achieved by the combination of two concentric terracotta pots. The shape of the outer pot (2) creates a reservoir between its wall and that of the inner pot (1). The single pot is created by clamping on their upper part (4) and then by enameling of the outer wall (6). The inner wall being porous, the reservoir water circulates gradually inside the pot by capillarity, ensuring the moisture of the soil (7). The water filling of the tank (3) is via a lateral orifice (5), which can be presented in the form of a fancy ornament. The device according to the invention is particularly intended for domestic use for the maintenance of indoor plants.

Description

The present invention relates to an autonomous terracotta device with an integrated reservoir for feeding water to plants.

The pot with water reserve is a device now common and widespread, available in most shops specializing in gardening. Whatever its form, it aims to simplify the maintenance of indoor plants by limiting the frequency of watering and ensuring proper and regular hydration. The vast majority of these products are made of plastic and are based on the same principle: a water tank is attached to the pot containing the plant and a textile wick allows the transport of water reserve to the soil, by the principle of capillarity. In order to meet a demand for greener and more authentic products, some devices have replaced plastic with terra cotta. However the integration of the tank with these devices seems to be a problem, as the hydration of the soil.

The aim of the device is to offer an alternative and natural solution to the products on the market while offering a level of quality at least equivalent.

The choice of terracotta is at the heart of the device presented, this material is the most common for growing plants. The pottery in general, and the work of the earth 2 - cooked in particular, is an ancestral know-how, which has only been marginally improved by current technology, which gives a traditional aspect to the device. In addition, the terracotta 5 allows a wide range of applications by its malleability and strength after cooking. Finally, the porosity of the terracotta allows in the case of our device to ensure the hydration of the plant. The accompanying drawing illustrates the invention: (1) is the porous inner pot containing the plant. (2) is the waterproof outer pot enameled on its outer surface. (3) is the water tank created between the two pots. (4) is the nip weld joining the inner and outer jars. 20 (5) is the fill port. (6) is the enamel covering the surface of the outer pot. (7) is the soil.

The constituent pot of the invention is an assembly of two pots (1 and 2) of different shapes at their upper edge (4), the difference in volume creating a void space. This volume will act as a water tank (3) - 30 An orifice provided on the outer pot (4) allows the water filling of the tank; it can be presented in the form of a fancy ornament. 3024641 - 3 - The pot is sealed by enameling the outer surface (6). The water contained in the tank can not escape through this wall; the only way out is to cross the porous wall of the inner pot 5 and then to be absorbed by the potting soil (7). Thanks to this device, based on both the principles of porosity and capillarity, the soil is constantly hydrated according to the needs of the contained plant, as long as the reservoir contains water. The invention as it is presented in this document can be realized with common tools, which any potter possesses. The device is made by assembling two pots at their point of contact, by pinching, columbine, or any other technique for welding. An orifice is drilled on the outer pot to allow subsequent filling of the tank. The cooking of the single pot thus created solidarise the two pots definitively. The final step of the realization consists of the enameling of the outer surface of the pot.

The device may be made by hand, as described above, or by any other modern means of mass production. Particularly adapted to the summer seasons and the 30 urban lifestyles, the outlets for this device are numerous.

Claims (6)

CLAIMS1) Device for autonomic hydration of plants characterized in that it is composed of an assembly of two terracotta pots. 2) Device according to the preceding claim characterized in that the two pots are secured by assembly at their upper edge. 3) Device according to claim 1 characterized in that the outer pot is sealed by enameling of its outer wall. 4) Device according to claim 1 characterized in that the empty space between the two pots forms a water tank around the inner pot. This reservoir is accessible through an orifice located on the external pot that can be presented in the form of a fancy ornament. 5) Device according to the preceding claims characterized in that the potential contact surface between the reservoir water and the wall of the inner pot is evenly distributed, including in the case where the water level in the reservoir would be low. 6) Device according to the preceding claims characterized in that the circulation of water from the reservoir to the soil is made possible by the porosity of the inner pot and by the capillary phenomenon.
