Since a and 74a can be arranged on the inner surface of the peripheral wall portion 29 at substantially equal intervals in the circumferential direction, water can be supplied to each portion of the soil 68 accommodated in the inner container in a more uniform state. It will be.

After mounting the water-absorbing string 74 in this way, soil 68 is put in the inner container 3 as required, and the plant is cultivated. As shown in FIG. 2, since the lower end portion 78 of the water-absorbing string 74 is immersed in the water W in the water storage tank 62 of the tray 5, the water-absorbing string 74 causes water to be absorbed by capillary action. Therefore, the sucked water can be effectively supplied to the soil 68 contained in the inner container 3. And the supply of water into the water storage tank 62 is
As shown in FIG. 2, for example, the tip end portion 71 of a water supply cylinder 70 attached to a water supply device 69 using a plastic bottle can be inserted into the jug recess 66. By doing so, the water in the water tank 62 is reduced to a certain level or more, and the water supply cylinder 7
When the lower end of 0 is exposed, a certain amount of water is
After 0, the water is automatically supplied into the water tank 62.

An annular gap portion 51 is formed between the peripheral wall portion 29 of the inner container 3 and the peripheral wall portion 6 of the outer container 3, and the upper end of the annular gap portion 51 is closed, so that the wall portion of the double flowerpot 1 is closed. Due to the double structure and the excellent heat insulating property of the annular gap portion 51, it is possible to prevent the roots from weakening under the influence of hot air even on a hot summer day, and to suppress the evaporation of water as much as possible. Further, in winter, since a good heat retaining effect is obtained by the heat insulating property, it is possible to prevent root rot due to freezing and the like. Note that, as shown in FIG. 12, when the non-water-supplying foam material 56 is housed in the annular gap portion 51, the heat insulating effect can be further enhanced.

Further, in the present embodiment, a large number of vent holes 46 are provided in a dispersed state in the peripheral wall portion 29 of the inner container,

The present invention has the following excellent effects. (1) In the double flowerpot according to the present invention, the outer container and the inner container are inseparably integrated, and an annular gap is formed between the peripheral wall portion of the outer container and the peripheral wall portion of the inner container, The upper end of the annular gap is closed. Therefore, due to the double structure of the wall of the double flower pot and the formation of the annular gap, excellent heat insulation performance is exhibited, the soil inside the pot is less susceptible to the outside air such as hot air and cold air, and the hot summer In addition, the evaporation of water can be suppressed as much as possible, and there is an advantage that it is not necessary to frequently water as in the conventional case. In addition, since such excellent heat insulating performance is exhibited, it is possible to enhance the moisturizing effect of the soil, prevent the roots from being weakened by heat, and in the winter, the soil is frozen and root rot is caused. It will be possible to prevent it from occurring.

(2) When a non-water-absorbing foam material is contained in the annular gap, the heat insulating effect can be further enhanced. If a water-absorbent fabric or a heat insulating material obtained by solidifying sawdust is contained, the absorbed water will rot and give off a bad odor.However, in the present invention, the foam material is used. Since a non-water-absorbing material is used as the above, such a problem does not occur.

(3) When a structure is employed in which a supporting protrusion for supporting a supported object from below is provided on the upper end side of the inner peripheral surface of the inner container so as to project upward, the supporting protrusion is It can be used to support various kinds of supported objects necessary for cultivation from below. For example, in order to hook the upper end of the water-absorbent string, or to support the pillar so that the pillar having the lower end embedded in the soil contained in the inner container does not fall down, the supporting protrusion is used. it can. When the support projection is used to hook a water-absorbing string whose lower end portion is in contact with water, water is sucked up by the capillary phenomenon through the water-absorbing string, and this is used as an inner container. There is an advantage that the soil stored in can be supplied up to it. If a relatively large-grained soil is stored in a flowerpot in consideration of drainage, even if the lower end of the soil is brought into contact with water, it is difficult to raise this water upward, but the lower end By using a water-absorbing string that comes into contact with water, water can be supplied to the upper part of the soil, water can be effectively supplied to the soil in the flowerpot, and water replenishment management becomes easy. In the case where the supporting protrusion is thus projected, an inclined bent portion that bends obliquely upward toward the upper end side of the peripheral wall portion of the outer container is provided on the upper end side of the peripheral wall portion of the inner container, and the upper surface of the inclined bent portion In the case where the supporting protrusion is projected upward, the inclination angle of the inclined bent portion is larger than the inclination angle of the peripheral wall portion, so that between the supporting protrusion and the peripheral wall portion,
There is an advantage that it is possible to secure a gap for easily hooking a supported object on the supporting protrusion. Further, since the inclined bent portion is provided so as to be bent obliquely upward, inconvenience such as water pooling on the upper surface of the inclined bent portion does not occur.

(4) Further, when a large number of ventilation holes are provided in a dispersed state in the peripheral wall portion of the inner container and the lower end of the annular gap portion is communicated with the outside air through the opening provided in the bottom portion of the outer container, Since the peripheral wall is not provided with vent holes, rising air can be taken into the soil contained in the inner container through the vent holes while preventing the entry of outside air and ensuring a heat insulating effect. it can. Further, since the vent hole is hidden by the peripheral wall portion of the outer container, it cannot be seen from the outside, and therefore,
Vents do not impair the appearance of the double flowerpot.

(5) A structure is provided in the outer peripheral portion of the bottom portion of the outer container, which is provided with a predetermined interval in the circumferential direction thereof and which can be used to put the lower end portion of the water-absorbing string-like object into the inserted state. In this case, for example, when the water-absorbing string-like object is folded in two and the folded portion is hooked on the support protrusion, the lower end portion of the hanging part of the water-absorbing string-like object is inserted into adjacent openings one by one.
