FR2544958A3 - Improvements to flower pots, vases and window boxes, peripheral or tubular airway - Google Patents

Abstract

The invention relates to aerating devices for flower pots, vases or window boxes. It comprises internal pots (2) which may be circular, made of porous or fibrous materials or waterproof with holes 3, in which case they will be covered on the inside 8 with rotproof synthetic materials or fine plastic mesh 9. The internal pots are kept at a certain distance from the wall 6 of the outer waterproof pots 7 by means of reliefs of variable design 5, or polyhedral ridges, or by construction. The air circulating between these two pots or these double walls improves the respiration of the plant's roots and the biological behaviour of the culture substrate. This substrate may also be directly aerated by means of tubular chimneys of porous or fibrous materials or waterproof materials with holes, being hollow in structure, or made of a compressed biodegradable chemical substance.

Description

 The present invention relates to improvements to pots, vases and flower boxes made of waterproof materials.

 Commercial flowerpots and planters are more and more used in plastic manufacturing, a lighter, less brittle and less cabbage material than terracotta vases and pots But these plastic materials are airtight, as in water. Therefore, they are less suitable for growing plants. In fact, gas exchanges between the growing medium, the plant's root system and the surrounding air no longer take place, or in insufficient volume. However, they are necessary for the respiration of the plant and for the favorable biological evolution of the culture substrate. The various devices adopted so far to overcome these drawbacks are clearly insufficient.

 The present invention overcomes these disadvantages, by providing an effective and sufficient circulation of air around the substrate, or inside, by means of weathering chimneys located either at the internal periphery of the sealed vessel, or located directly in this substrate. , in a configuration appropriate to the shape of the vase, pot or planter.

 In the first exemplary embodiment, a second pot, of general shape identical to the first, exterior and sealed, is interposed between it and the growing medium; it is made of porous or fibrous material, or even perforated plastic and provided at its internal faee with a rot-proof fabric with a large mesh, or with a fine mesh also made of plastic. Various non-limiting embodiments of this first device are described below.

 The second device uses independent chimneys, essentially tubular and hollow, constructed of porous, fibrous or finely drilled plastic materials. According to another idea of this device, the tubular elements are in degradable chemical agglomerates gradually supplying to the growing substrate, thus to the plant, the nutritional elements which it needs to feed itself.

 According to the invention, the device with peripheral chimneys consists of a polyhedral pot 1 or circular 2, pierced with holes 3, of dimensions and in number not defined; the edges 4 of the polyhedron and the grooves 5 of the truncated cone create a relief effect which keeps the pots 1 and 2 at a distance from the inner wall 6 of the sealed outer pot 7. The inner walls 8 of the pots 1 and 2 are covered either with rot-proof synthetic fabrics, ie of fine plastic mesh 9. The air circulates between the walls 6 of the sealed pot and 10 of the internal pot in the crown sectors 11 or the arches / hoops intervals 12.

 According to another embodiment, FIG. 5, the internal pot is made of spongy material or of braided synthetic fibers in the form of a truncated cone of sectors or continuous.

 FIGS. 6 and 7 are two embodiments of plastic inner pots with vertical rectilinear or oblique braided external reliefs forming a framework in which takes place a tray of fine mesh which can be removable or fixed by gluing, welding. Figure 8 shows a sectional pot in fine mesh or other, whose rectilinear, vertical reliefs 13 are tubular and can receive tubular elements 14, themselves permeable to air. FIG. 9 shows an embodiment of an internal pot by molding with holes and circular reliefs 15. An internal coating is also provided. Figure 10 shows two sectional profiles of a double-walled flowerpot, integral with construction. On the left, the inner wall 8 comprises cannulas 16 for supplying air into the substrate; their length is variable and they can be split or striated. The air arrives at the upper part of the walls through the openings 11 in crown sectors ... On the right, the internal wall 8 is simply pierced with holes 3 and covered with a synthetic fabric or a fine plastic mesh 9.

 According to FIG. 11, different embodiments of independent, tubular aeration chimneys, made of pierced hollow material 17, or porous material 18, or fibrous material 19.

 The devices of the present invention are capable of taking any desired shape and being constructed of any suitable material.
