1. The outer pot body The shape of the outer pot body 12 in the flower pot 10 is not particularly limited, but as an example, as shown in FIG. 2, it is basically a cylindrical shape having a bottom 12c, For example, when a semi-conical trapezoidal inner pot body 14 is fixedly disposed, a gap is preferably formed between the inner pot body 14 and the inner pot body 14 so as to function as the water supply unit 15.
Therefore, the height (L1) of the outer pot body 12 illustrated in FIG. 2 is the height from the bottom portion 12c to the upper end surface of the side wall 12b ′ inserted into the elastic member (seal member) 16a of the seal portion 16. In general, it is preferably a value in the range of 3.5 to 12.5 cm, more preferably a value in the range of 4.5 to 8.5 cm.
Moreover, although the height (L2) of the outer pot body 12 means the height from the bottom part 12c to the upper end surface of the flange part 12a, it is preferable that it is a value within the range of 3-12 cm normally. A value in the range of 4 to 8 cm is more preferable.

Moreover, as shown in FIG. 2, it is preferable that the flange part (protrusion part) 12a is provided along the side wall 12b of the outer pot body 12. As shown in FIG.
The reason for this is that it is provided in the outer pot body by being configured in this way, and the flange portion projecting in the horizontal direction and the side wall of the inner pot body are in contact with each other, making it easy to position the inner pot body in the height direction. This is because.
That is, since the lower surface of the flange portion of the outer pot body and the end surface of the side wall of the inner pot body are in contact with each other with a predetermined area, the sealing performance at the seal portion can be finely and accurately adjusted.

Therefore, regarding the form of the outer pot body 12 illustrated in FIG. 2, it is preferable that the diameter (W1) of the opening provided at the upper part is normally set to a value within the range of 3 to 12 cm. A value within the range is more preferable, and a value within the range of 5 to 8 cm is even more preferable.

Therefore, as shown in FIG. 1, a seal portion formed by a folded portion 14 a and an elastic member 16 a mounted therein at a predetermined position between the outer pot body 12 and the inner pot body 14. 16 is provided, the elastic member 16a and the upper end surface of the side wall 12b of the outer pot body 12 are in close contact with each other, and a part of the side wall 12b is inserted into the elastic member 16a, It exhibits sealing properties.
That is, even with such a simple structure, the seal part 16 adjusts the internal pressure (negative pressure) of the water supply part 15 over a relatively long period of time, for example, 15 days or more. Since an appropriate amount of water is slowly supplied while adjusting, the occurrence of root rot can be suppressed.

Moreover, regarding the form of the inner pot body 14 illustrated in FIG. 3, the height (L3) includes the height of the folded portion 14 a and the like, for example, a value within a range of 3.5 to 12.5 cm. It is preferable that it is a value within the range of 4.5-8.5 cm.
Further, the height (L4) of the inner pot 14 corresponds to a value obtained by removing the thickness (about 1 mm) of the bottom from the height (L1) of the outer pot 12 illustrated in FIG. For example, a value within the range of 3 to 12 cm is preferable, and a value within the range of 4 to 8 cm is more preferable.

Moreover, regarding the form of the inner pot body 14 illustrated in FIG. 3, the diameter increases in the longitudinal direction from the cylindrical leg portion 14 e provided on the back side of the bottom surface 14 c toward the upper folded portion 14 a. It is preferable that it is a taper shape.
More specifically, the angle between the vertical direction and the side wall of the inner pot body 14 is preferably a value in the range of 2 to 45 °, more preferably a value in the range of 5 to 30 °. Preferably, the value is in the range of 10 to 20 °.

In addition, the outer diameter (opening portion outer diameter, W4) of the folded portion 14a is generally 0.2-3 cm than the inner diameter (opening portion inner diameter, W3) of the folded portion 14a in consideration of the size of the seal portion. It is preferable to enlarge, more preferably 0.5 to 2 cm, and still more preferably 0.8 to 1.5 cm.
In addition, the height (L5) of the cylindrical leg portion 14e provided on the back side of the bottom surface 14c affects the size of the water passage port 14h, and thus the attachment and fixing properties of the elastic member 16a. Usually, it is preferable to set it as the value within the range of 0.2-3 cm, and it is more preferable to set it as the value within the range of 0.3-2 cm.

(2) Inner pot Also, as illustrated in FIG. 6 (a), the inner pot body 14 of the inner pot body 14 is arranged so as to be in direct contact with the plant 30 to be planted in the flower pot 10 and to facilitate transplanting and the like. It is also preferable to provide the innermost pot 50a as an attachment part of the inner pot body 14 on the inner side.
More specifically, the innermost pot 50a is a cup-like material accommodated in the inner pot body, and depends on the size of the innermost pot, for example, 1 to 30 slit holes 50a. It is preferable that it is an olefin resin cup provided with a '(width: 0.1 to 5 mm, length: 0.5 to 3 cm).

3. Seal Part Further, as illustrated in FIG. 1, the seal part 16 in the flower pot 10 is provided with a folded part 14 a on the upper end surface of the side wall 14 b of the inner pot 14, and the folded part 14 a and the outer pot body 12. The elastic member 16a is fixedly disposed between the upper end surface of the side wall 12b '.
That is, the internal pressure of the water supply part 15 comprised from the folding | returning part 14a and the elastic member 16a in the predetermined position between the outer pot body 12 and the inner pot body 14, and by extension, the supply speed of water are adjusted. A sealing portion 16 is provided for this purpose.
Therefore, even with a simple structure, it is possible to provide a flower pot with less root rot generation while adjusting the water supply rate in relation to the internal pressure (negative pressure) of the water supply section over a long period of time.

Moreover, it is preferable that the seal part is configured by arranging an O-ring or a plate-like rubber as an elastic member in a folded part provided at one end of the inner pot body.
The reason for this is that with such a configuration, even if it has a simple structure, it exhibits good sealing performance in the seal portion, and as a result, it is possible to adjust the water supply rate over a longer period of time. .
In addition, it is preferable that the diameter (or thickness) of the cut surface of the O-ring or the plate-like rubber is set to a value within the range of 0.2 to 5 mm so as to be placed in pressure contact with the gap between the folded portions. More preferably, the value is in the range of 0.5 to 3 mm.

In addition, the type of elastic member that constitutes a part of the seal portion is not particularly limited. For example, silicone rubber, olefin rubber, styrene rubber, natural rubber, chloroprene rubber, butyl rubber, vinyl chloride rubber, One kind alone or a combination of two or more kinds such as acrylic rubber, urethane rubber, and fluororubber may be used.
Particularly, among these, silicone rubber is easy to obtain excellent durability and water repellency as well as good sealing properties, and olefin rubber is relatively inexpensive and has excellent water resistance. These properties are preferable because properties and water repellency are easily obtained.

4). Up-and-down position variable member Moreover, about the aspect of the up-and-down position variable member 13 in the flower pot 10, for example, as shown in FIG. 2, a screw part formed of a male screw part 12d and a female screw part 14d, or a pair of tapered shapes Even a nested structure is preferable.
The reason for this is that the height position of the inner pot body inside the outer pot body can be accurately adjusted to a desired position by simply changing the tightening degree of the screw section by providing the screw section and the like in this way. This is because it can.
In addition, by providing the vertical position variable member at the center of the bottom surface of the inner pot body, the fixing position of the inner pot body within the outer pot body can be easily determined, and the width of the gap constituting the water supply section is also accurate. It can be adjusted well.

More specifically, as shown in FIG. 2 and FIG. 3, in the vertical position variable member 13 with the center portions 12f and 14f defined, the guide members 12g and 14g are provided so that the inner portion of the outer pot body 12 is provided. There is an advantage that the fixing position of the pot body 14 is determined more accurately and the sealing performance in the seal portion is also improved.
Therefore, as shown in FIGS. 2 and 3, when the vertical position variable member 13 is a threaded portion, the male screw guide member 12g and the female screw guide member 14g are provided on the outer side of the male screw and the inner side of the female screw, respectively. Thus, the mechanical strength and dimensional stability of the thread portion as the vertical position variable member 13 can be improved.
Furthermore, if it is such an up-and-down position variable member (screw part) 13, there is also a manufacturing advantage that it can be simultaneously formed when each of the outer pot body and the inner pot body is formed by an injection molding method or the like. .
Therefore, if the vertical position variable member is such a screw portion, the sealing performance in the seal portion can be finely adjusted even if it has a simple structure.
Therefore, the water supply speed can be adjusted to an appropriate range by using a predetermined vertical position variable member, and watering can be omitted for a long period of time, or root rot can be prevented.

In addition, as described in the second embodiment, as a mode in which another vertical position variable member is combined, a screw portion is provided between the outer pot body and the inner pot body around the seal portion (downward). It is also preferable to provide it.
The reason for this is that by providing a plurality of vertical position variable members in the vertical direction, the outer pot body and the inner pot body can be further screwed together, and the relative distance between the outer pot body and the inner pot body. This is because the sealing performance at the seal portion can be improved while making the variable.

Nonwoven Fabric Member Further, the nonwoven fabric member 20 in the flower pot 10 uses water that is stored in the water supply section 15 that is a gap between the outer potted body 12 and the inner potted body 14 as shown in FIG. This is a part for gradually supplying the water into the inner pot body 14 through the water passage 14h provided below the inner pot body 14.
That is, the water stored in the water supply unit 15 is supplied into the inner pot body 14 through the nonwoven fabric member 20 (20a, 20b) partially protruding from the water passage port 14h using a capillary phenomenon or the like. For this reason, the water supply rate can be adjusted to an appropriate range over a longer period of time.
Moreover, about the form of the nonwoven fabric member 20, although it depends on the form and size of the flower pot, or the kind of the plant, for example, as shown in FIGS. 4A to 4B, the planar shape is substantially circular.
