Watering device intended to be fitted to a growing container, comprising an independent reservoir

Abstract

Device for watering plants configured to fit into a growing container, such as a pot. The device includes an external casing intended to be placed inside the growing container and to be at least partially buried. The casing delimits a housing having an open top end intended to protrude from or lie flush with the soil, and a bottom end having a passage in the soil. The device is further equipped with a water reservoir positioned inside the housing and having an orifice around which a water diffusion system is removably mounted. The diffusion system is designed to pass through the passage of the casing.

Description

(1) In any case, the invention will be better understood by means of the following description with reference to the appended schematic drawing illustrating as a non-limiting example, an embodiment of this watering device.

(2) FIG. 1 is a perspective view thereof;

(3) FIG. 2 is a sectional side view thereof;

(4) FIG. 3 is an exploded perspective view thereof;

(5) FIG. 4 is a top view of a growing container of circular section equipped with a watering device;

(6) FIG. 5 is a top view of a growing container with a square section, equipped with a watering device.

(7) FIG. 1 illustrates a watering device 1 intended to equip a growing container R, such as pot.

(8) This device 1 comprises: an outer casing 2 delimiting a housing 3 and having an open upper end 4 and a lower end 5 having a passage 6, a water reservoir 7 positioned in the housing 3 and having a lower orifice 8 and an upper open end 9, a water diffusion system 10 mounted on the water reservoir 7, communicating with its orifice 8, a lid 11 closing the open end 8 of the water reservoir 7.

(9) The casing 2, in a synthetic material, includes as illustrated in FIG. 1, a side wall 12 connecting together the upper 4 and lower 5 ends. The side wall 12 includes two side surfaces 13 approximately forming an angle of 90 relatively to each other. Both side surfaces 13 are connected to each other through an intermediate surface 14 forming a truncation of the angle formed by both side surfaces 13. The side surfaces 13 each have an edge 15 opposite to the angle. The edges 15 of the side surfaces 13 are connected through a curved portion 16. The curved portion 16 has a horizontal section with the general shape of a circular arc.

(10) The side wall 12 has, as illustrated in FIG. 2, a first upper portion 17 having a constant horizontal section and a lower portion 18, in the continuity of the upper portion 17, having a horizontal section, the surface of which continuously decreases towards the lower end 5.

(11) The side wall 12 has stiffening ribs/grooves 19 substantially oriented vertically.

(12) The passage 6 present at the lower end 5 of the casing 2 is of circular shape in order to allow the passing of the water diffusion system 10.

(13) The side wall 12 delimits with the upper 4 and lower 5 ends of the outer casing 2 the housing for the water reservoir 7.

(14) The water reservoir 7, also made in a synthetic material, has, as illustrated in FIG. 3, a shape mating that of the housing 3 so as to be received therein. The water reservoir 7 includes, at the open end 9, returns 20 which will bear upon the edges 21 of the upper end 4 of the casing 2.

(15) The water reservoir 7 includes a threaded tubular portion 22 around the orifice 8 in order to allow attachment of the water diffusion system 10.

(16) The water diffusion system 10 is a water diffusion system 10 similar to the one described in document EP 1406480. The water diffusion system 10 includes a porous portion 23 with a general conical shape, made in ceramic. The water diffusion system 10 further includes a threaded tubular portion 24 conformed in order to cooperate with the threaded tubular portion 22 of the water reservoir 7.

(17) The threaded tubular portion 22 of the water reservoir 7 and the threaded tubular portion 24 of the water diffusion system 10, respectively form the first and second means for attaching the water diffusion system 10 onto the water reservoir 7.

(18) The lid 11 is laid out so as to close the open end 9 of the water reservoir 7. The lid 11 has a grip handle 25 allowing it to be handled.

(19) The installation of the device 1 may be achieved upon planting a plant into the soil in a growing container 9 or be achieved subsequently in a flowing container R already provided with one or several plants.

(20) In the first case, the growing container R is partly filled with earth so that the device 1 may rest on the earth. In the case when the growing container R has a circular horizontal section, as shown in FIG. 4, the device is positioned in the growing container R so that the curved portion 16 bears upon the internal wall of the container and so that the lower end 5 of the outer casing 2 bears upon the soil.

(21) In the case when the container has a rectangular or square section, as shown in FIG. 5, the device is positioned in the growing container R so that each side surface 13 bears upon one of the sides forming an angle of the container and so that the lower end 5 of the outer casing 2 bears upon the soil.

(22) Thus, the water diffusion system 10, crossing the passage 6 made at the lower end 5 of the outer casing 2, is in direct contact with the soil. Once the device 1 is in place, the plant may be positioned in the growing container R and the filling of the growing container R with earth may be completed so as to have the upper end 4 of the outer casing 2 lie flush therewith.

(23) In the case when the installation is achieved in a growing container R already provided with a plant, a portion of the earth is removed at the location intended for the device 1. The device 1 is then placed according to a position similar to the one described in the first case. Once the device 1 is in place, a portion of the removed earth is reintroduced into the growing container R so as to bury the device 1 so as to allow the upper end 4 of the outer casing 2 lie flush therewith.

(24) As this is obvious, the invention is not limited to the sole embodiment of this watering device, described above as an example, on the contrary it encompasses all the alternative embodiments. Thus notably the water diffusion system may assume another shape and include a system of the dripping type different from a cone-shaped porous portion.
