[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to specific embodiments. 1, 2, and 3 show an embodiment according to claim 1, and FIG. 1 is a cutaway side view of the flowerpot of the present invention, which is an AA cross-sectional view of FIG. 2. FIG. 2 is a top view, and FIG. 3 is a front view. The flowerpot is composed of an upper container A and a lower container B. The upper container A has an inner cylinder 1 and an outer cylinder 2 circumscribed at a position where a required gap is provided on the outer periphery of the inner cylinder 1. The upper ends of the bodies are integrated with each other to form a flange-shaped upper wall 3. With this configuration, a cylindrical hollow portion having a sealed upper end and an open lower end is formed between the two cylindrical bodies, and this space serves as a water storage tank Y of the flowerpot of the present invention.

The opening at the lower end of the water storage tank Y is closed by the upper surface of the bottom wall 10 of the lower container B when the upper container A and the lower container B are fitted. When both containers are fitted, the hollow portion x inside the inner cylinder 1 becomes a portion for filling the soil, and the lower container B at the lower end of the hollow portion x
The bottom water tank z which forms a constant liquid level is formed on the upper surface of the bottom wall 10. Since this water storage tank Y is provided on the outer peripheral portion of the flowerpot, the volume is much larger than the apparent volume shown in FIG. 1, and a volume equal to or greater than the hollow portion x inside the inner cylinder 1 can be secured. The volume can be made much larger than that of a conventional flowerpot with a water tank provided with a water tank at the bottom of the flower pot. Further, when a transparent or translucent material is used for the upper container A, the liquid level that changes in the water storage tank Y can be confirmed at a glance, and when an opaque material is used, it will be described later.
If the liquid level inspection window 18 is provided, the liquid level change in the water storage tank Y can be visually observed in the same manner as in the case where the transparent material is used. As shown in FIGS. 1 to 3, the upper container A of the flower pot has a truncated cone shape, but any shape may be used as long as it can be molded.

The upper wall 3 is a flange portion at the upper end of the flowerpot in which the upper ends of the inner cylinder 1 and the outer cylinder 2 are integrated. When the width of the upper wall 3 is reduced, the volume of the water storage tank Y is reduced. When the width of the wall 3 is increased, the capacity of the water storage tank Y is synergistically increased. However, when the width of the upper wall 3 is unnaturally increased, the beauty of the flowerpot, which is a decorative product, is impaired. It is preferable to set so that the size of the water inlet 4 for water injection can be secured.

The water inlet 4 is an opening provided in the upper wall 3 and may have any shape, but as shown in FIGS. 2 and 3, a concave portion is formed in a part of the upper wall 3 to facilitate water injection. The water injection portion is widened, an opening is provided in the bottom wall of the concave portion, and a cylindrical body that hangs from this opening to a predetermined position in the water storage tank Y is provided. In the flowerpot of this configuration, the lower end position of the water injection tube 5 serves as a reference for the constant liquid level configured in the bottom water tank z as described in detail in the principle description. Therefore, when the lower end position of the water injection tube 5 is moved up and down, the constant liquid level appearing in the bottom water storage tank z changes accordingly. For this reason, since the amount of water supplied to the soil portion changes depending on the lower end position of the water injection cylinder 5, it is preferable to preset the type of planting, that is, one that requires a large amount of water and one that does not.

The shape of the water injection cylinder 5 may be arbitrary, as long as it has an inner diameter that does not hinder water injection. The following is a specific example of the configuration of the water injection cylinder 5. 1. When the height of the flower pot is short, the cylindrical portion of the water injection tube 5 can be easily formed, so that the water injection tube 5 and the upper container A can be integrated. However, when integrally configured, the upper container A
When stacking and storing, the water injection cylinder 5 hinders the stacking and the storage efficiency deteriorates. 2. When the height of the flower pot is high, it may be difficult to mold the cylindrical portion of the water injection tube 5. Therefore, as shown in FIGS. May be fitted to the fitting hanging tube 4A provided at the lower end of the opening. With this configuration, the water injection cylinder 5 becomes detachable, and the upper containers A can be densely stacked with the water injection cylinder 5 removed, so that storage efficiency is improved. 3. As shown by the broken line in FIGS.
The upper end of the water injection cylinder 5 is fitted into the water injection cylinder 5 by insertion.
A projection plate 5A is provided at the upper end of the projection plate 5A, and the projection plate 5A is protruded to the water injection port 4 so that the water injection cylinder 5 can be moved up and down by the vertical operation of the projection 5B provided at the upper end of the projection plate 5A. The lower end position of 5 also moves up and down in conjunction with it, so that the lower end position of water injection tube 5 can be changed, and the constant liquid level appearing in bottom water tank z can be adjusted from outside the flowerpot. See H, L at the lower end of the water injection cylinder 5 in FIG. When the lower end position of the water injection cylinder 5 is pushed down to the position of L in FIG. 1 leaving a gap between the water inlets 5C near the upper surface of the bottom wall 10 of the lower vessel B, the water storage tank Y passes through the water passage 9 and the bottom water tank z. Water can be completely shut off and the soil can be dried when required. Further, by adjusting the position of the projection 5B, it is possible to adjust the water supply condition to be optimal for the planting. By adding this function, the flowerpot of the present configuration can cope with a flowerpot having any property, and its use has been expanded.

The on-off valve 6 is provided at an arbitrary portion of the upper wall 3,
It is sufficient that a ventilation path is formed so that the water tank Y can communicate with the outside of the upper container A at the time of water injection, the water path can be shut off after the water injection is completed, and the upper end of the water tank Y is sealed. The on-off valve 6 can have many structures, and some of them are introduced below by specific examples. 1. As shown in FIG. 4, a hanging cylinder 6A penetrating vertically through the upper wall 3 is provided at the lower end of the upper wall 3, and a sealing rod 6B that can be fitted closely into the hanging cylinder 6A and that can move up and down is inserted into the sealing rod 6B. When the protrusion 6F provided at the upper end is moved upward, the upper end of the slit 6C provided at the lower end of the sealing rod 6B is slightly exposed to the outside, and a ventilation path through which the water storage tank Y can communicate with the outside through the slit 6C. When water injection is completed, when the protrusion 6F at the upper end of the sealing rod 6B is pressed down, the ventilation path is shut off by tight fitting between the outer peripheral wall surface of the upper end part of the sealing rod 6B and the inner wall surface of the hanging cylinder 6A. An on-off valve 6 capable of sealing the upper end of the tank Y. 2. As shown in the opening / closing valve 6 of FIGS. 1, 2, and 3, a sealing rod 6B inscribed in the hanging cylinder 6A is provided, and a lever 6D capable of rotating the sealing rod 6B is provided at the upper end of the sealing rod 6B. This is an example in which 6D is also used as a cover of the water inlet 4. When the water supply lever 6D is rotated outside the flower pot, the concave portion of the water injection port 4 is exposed, and at the same time, the position of the slit 6C provided on the sealing rod 6B and the position of the groove-shaped slit provided on the inner wall surface of the hanging cylinder 6A overlap. Thus, a ventilation path can be formed between the water storage tank Y and the outside. When water injection is completed, the lever 6D is returned to the original position above the water injection port 4, and when the water injection port 4 is covered, the slit 6C at the lower end of the sealing rod 6B blocks the ventilation path by joining with the inner wall surface of the hanging cylinder 6A. An on-off valve 6 in which the upper end of the water storage tank Y is sealed.

In the above-mentioned items 1 and 2, if the operator forgets to operate the on-off valve 6 in the closed state, the water in the water storage tank Y flows out of the flowerpot. In the second item, the on-off valve 6 is opened. If left unattended, the lever 6D will protrude outside the flowerpot, and it can be found at a glance that the valve is in the open state, and it is possible to prevent forgetting to operate the valve in the closed state. When the lever 6D is returned to the position above the water inlet 4, the entire periphery of the flange-shaped upper wall 3 has a uniform shape, and the beauty of the flowerpot can be improved. 3. In the first and second items, if the operation to close the valve is forgotten, the water in the water storage tank Y flows out, and as shown in FIG.
The inner wall surface A and the outer peripheral wall of the sealing rod 6B are formed in a slightly conical shape, and the sealing rod 6B is provided using a spring 6G provided on the upper part of the sealing rod 6B and a restoring force of rubber or elastic resin.
Is always lifted upward, and the outer wall surface of the sealing rod 6B and the hanging cylinder 6
By joining with the inner wall surface of A, the valve portion (air passage) is sealed. Projection 6 on top of sealing rod 6B when water is injected
When F is depressed, a narrow gap is formed between the two wall surfaces,
This can be configured as a ventilation path.
When the water injection is completed, when the hand is released from the protrusion 6F, the sealing rod 6B is moved upward by the restoring force of a spring or the like, and the ventilation path is automatically shut off. Since the valve is automatically closed even if the operation to the state is forgotten, the outflow of water from the water storage tank Y can be prevented. The valve portion (air passage) may have a configuration of the slit 6C.

The lower container B is a dish-like body, and has a fitting portion 7 with the lower end of the inner cylinder 1 of the upper container A and a fitting portion 8 with the lower end of the outer cylinder 2 on the upper surface of the bottom wall 10. Various structures can be considered for this fitting structure, and the necessary conditions are that the upper container A and the lower container B
When the water storage tank Y is in the fitted state, the opening at the lower end of the water storage tank Y can be sealed with the upper surface of the bottom wall 10, so that the fitting parts 7, 8 of the containers A and B are not easily detached. In addition, since a water head pressure equivalent to the height of the flowerpot is temporarily applied to the fitting portions 7 and 8 during water injection, the fitting portion 8 at the lower end of the outer cylinder 2 needs a sealing structure that can withstand the above-mentioned water head pressure. In addition, the fitting surface of the fitting portion 7 at the lower end of the inner cylinder 1 is used as a water passage 9 from the water storage tank Y to the bottom water storage tank Z. State.

In a structure in which the degree of sealing of the fitting portion 7 at the lower end of the inner cylinder 1 is increased, the space between the water storage tank Y and the bottom water storage tank Z may be completely shut off. In such a case, It is necessary to provide a narrow or fine through-hole at the lower end of the inner cylinder 1 or at the fitting portion 7 at the lower end of the inner cylinder 1 so that the water storage tank Y and the bottom water storage tank Z can communicate with each other. is there. If the gap of the narrow through hole of the water passage 9 is large, the bottom water storage tank Z becomes full by the time of completion of water injection and overflows from the perforated plate 11A at the upper end of the ventilation / drain cylinder 11. A water passage 9 which is configured as a narrow gap that does not clog and that can limit the flow rate so that the bottom water storage tank Z does not become full until the water injection is completed is appropriate. However, when using outdoors or in combination with a saucer, or when pouring water at a water site, overflow to the outside can be tolerated. Therefore, allow a margin for the diameter of the narrow through hole of the water passage 9. Can be.

Since the structure of the fitting portion 7 at the lower end of the inner cylinder 1 can be considered variously and is related to the upper surface structure of the bottom wall 10, several specific examples combining the above-mentioned structures will be introduced. I do. 1. FIG. 6 shows an example in which a fitting portion 7 and a fitting portion 8 with the lower end of the inner cylinder 1 and the lower end of the outer cylinder 2 are formed as concave grooves on the upper surface of the bottom wall 10 of the lower container B. Since it cannot be configured, it is necessary to remove or lower a part of the concave groove of the fitting portion 7 to configure the water passage 9. Further, in this structure, when the hollow portion x is filled with soil, the soil may enter the fitting surface of the fitting portion 7 and reduce the fitting degree. A required clearance is provided between the inner wall surface of the inner cylinder 1 and the inner wall surface of the inner cylinder 1, and a cylindrical body 1 </ b> B that hangs down to the upper surface of the bottom wall 10 is provided.

In the flowerpot according to the first aspect, the fine hole 1C at the upper end of the cylindrical body 1B does not need to be particularly provided. However, when applied to the flowerpot according to the second aspect, the fine hole 1C is required because it serves as an exhaust passage. The top surface structure of the bottom wall 10 in FIG. 6 is provided with a ventilation tube / drainage tube 11 (hereinafter referred to as a ventilation tube 11) at the center, and the ventilation tube 1 is provided.
At one upper end, a perforated plate 11A having slits or pores for preventing soil from falling is provided. Since the bottom water tank Z is formed between the outer peripheral surface of the ventilation cylinder 11 and the inner wall surface of the inner cylinder 1, the upper end of the ventilation cylinder 11 is higher than the lower end position of the water injection cylinder 5 forming the constant liquid level. 2. As shown in FIG. 1, a bottom wall integrated with the inner cylinder 1 is provided at the lower end of the inner cylinder 1, which is referred to as an upper bottom wall 1A, an opening is provided at the center of the upper bottom wall 1A, and a bottom wall of the lower container B is provided. A ventilation tube 11 is set up on 10, and the outer peripheral end of the opening and the outer peripheral wall surface of the ventilation tube 11 are joined together, and this joint can be used as the fitting portion 7. The water passage 9 having this configuration has a long joining surface, so that it is difficult to be clogged, and the fitting degree can be increased. 3. FIG. 7 shows a configuration in which an upper bottom wall 1A integrated with the inner cylinder 1 is provided at the lower end of the inner cylinder 1 and a ventilation cylinder 11 is provided on the upper surface of the upper bottom wall 1A. A configuration in which the outer wall surface of the cylindrical body and the inner wall surface of the ventilation cylinder 11 are fitted,
This portion becomes the fitting portion 7. In this configuration, a narrow through hole is provided at an arbitrary portion of the upper bottom wall 1A or at an arbitrary portion of the lower end of the inner cylinder to form the water passage 9. 4. The structure of the fitting portion 7 in FIG. 8 is the same as that in FIG. 6, and employs a concave groove. The upper surface structure of the bottom wall 10 is an example in which a ventilation tube 11 is provided at the center of the bottom wall 10, and in FIGS. 9, 10 and 11, the ventilation tube 11 is provided at the outer peripheral portion of the bottom water tank Z and at the inner wall surface of the inner tube 1. Fan-shaped ventilation tube 11 on the upper surface of bottom wall 10
Are arranged in a plural number (three in FIG. 10), and are different in shape but structurally the same. In this configuration, as shown in FIG. 8 or FIG. 9, the perforated plate 11A at the upper end of the ventilation tube 11 is removed, a flat partition plate 12 is provided slightly above the ventilation tube 11, and the hollow portion X is divided vertically. ing. The upper space is a soil filling portion of the hollow portion X, and the lower end of the lower space is a bottom water storage tank Z, and the upper end is a ventilation path as shown by a broken line in the figure. At the lower end surface of the partition plate 12 at the upper end of the ventilation tube 11, a predetermined interval from the upper end of the ventilation tube 11 is provided.
An umbrella-shaped hanging cylinder 12A that covers the upper end is provided. An opening 12B is provided in the other portion of the partition plate 12, and a cylindrical body 12C that hangs down from the opening 12B to the upper surface of the bottom wall 10.
And a water supply cylinder for supplying water to the soil portion by utilizing the capillary action of the soil filled in the cylindrical body 12C. Slits or small holes 12D are provided in the partition plate 12 other than the above-mentioned two portions so that the soil does not fall, and these serve as a ventilation port and a drain port.

8 and 9 to 11, even if water is directly sprayed on the soil portion, if the amount of water sprayed is small, water dropped from the soil portion is stored in the bottom water storage tank Z, and water is discharged from the ventilation tube 11. Since it does not drop directly and soils the floor, it is not necessary to use a saucer. However, when used outdoors, if the amount of water spray increases due to rainwater, etc.
D, through the lower space, through the ventilation tube 11. 8 and 9, the partition plate 12 is formed integrally with the upper container A, but may be formed separately. In the case where the partition plate 12 is formed separately, many fitting structures other than those described above and the bottom wall 10 are formed. Although a structure is conceivable, any configuration may be used as long as a narrow water passage 9 is secured. In addition, when the area of the opening 12B is increased, the amount of water supplied to the soil filling part X increases proportionally, so that the opening 12B
Is preferably set according to the type of the corresponding plant.

The shape of the outer peripheral wall 13 may be arbitrary, but in the flowerpot of the present invention, a hook 13A for preventing the detachment from the upper container A is provided at the upper end portion so as to stand upright in a state close to the outer wall surface of the outer cylinder 2. The height of the outer peripheral wall 13 may be arbitrarily set. However, when it is considered that the fitting portion 8 deteriorates over time, the sealing degree of the fitting portion 8 is reduced, a gap is formed, and the liquid overflows from the fitting portion 8, 13
Is set higher than the lower end position of the water injection tube 5, there is no fear that the liquid will overflow from the fitting portion 8 when left unused during use. In addition, when the sealing structure of the fitting portion 8 is reliable, or is bonded or welded, the height of the outer peripheral wall 13 may be arbitrary or may be omitted.

The pedestal 14 has a hollow portion at the lower end of the bottom wall 10 and connects the hollow portion in the cylinder of the ventilation tube 11 and the outer peripheral portion of the lower end of the flowerpot by a hollow path. As an example of the shape, a slight cylindrical body is hung down from the outer peripheral end of the bottom wall 10 of the lower container B, and a cutout portion is provided at a key point, and this is used as the ventilation port 15. The shape of the pedestal 14 may be arbitrary as long as a hollow path that can communicate with the base can be formed. In the case of using a tray (tray) together, if there is a rib on the upper surface of the tray, a hollow portion can be formed at the lower end of the bottom wall 10, so the pedestal 14 becomes unnecessary. Just do it.

FIGS. 9, 10 and 11 show a specific embodiment according to claim 2, and FIG. 9 is a cutaway side view of a flowerpot.
A sectional view, FIG. 10 is a top view, FIG. 11 is a front view of FIG. 10, and is a partial BB sectional view of FIG. As shown in the cross-sectional view of FIG. 9, the water injection cylinder 5 at the lower end of the water injection port 4 provided in FIG. 1 is removed, an openable and closable sealing stopper is attached to the water injection port 4, and the water injection port 4 is provided on the upper wall 3. 9 and 11, a narrow slit 17 or a lower end of the inner cylinder 1 reaching a predetermined height from the lower end of the inner cylinder 1 at the lower end of the inner cylinder 1 as shown in the cross section of FIGS. At a predetermined position slightly above, there is provided a through hole 17A, which is a fine hole penetrating the inner cylinder 1 from side to side. Since the structure other than that described above is the same as that of the first embodiment, the fitting portion 7, the fitting portion 8, and the bottom wall 10 of the lower container B are provided.
May be referred to the above-described structure. Note that FIG.
In the structure of the lower container B, three ventilation cylinders 11 are arranged along the inner wall surface of the inner cylinder 1 as shown by a broken line in FIG.
Is an example in which an opening 12B is provided at the center of the frame. However,
The principle of forming the constant liquid level in the bottom water storage tank Z is different from that of claim 1 and will be described in detail in the principle description.

FIGS. 12 to 16 show a liquid level inspection window 18 according to the third embodiment.
13 to 16 are diagrams showing the detailed configuration of the fitting structure around the liquid level inspection window 18. The configuration of the liquid level inspection window 18 is the same as that of Japanese Patent Application No. 8-21753, but a predetermined portion of the back surface of the transparent or translucent sealing plate 18A serving as a window for viewing the liquid level in the water storage tank Y is provided. The difference is that the colored plate 18C is provided in parallel at the position where the gap is provided. This configuration is disclosed in Japanese Patent Application No. Hei 8-21753.
Also applicable to

The liquid level inspection window 18 is provided with a cutout at the lower end of the outer cylinder 2 and a sealing plate 18A fitted to the outer peripheral end of the cutout except the lower end. As shown in FIGS. 13 to 16, a concave groove 18B is formed on the outer periphery of the sealing plate 18A except for the lower end.
And the outer periphery of the notch portion is fitted. Conversely, a concave groove is formed on the outer periphery of the notch,
The sealing plate 18A may be formed in a flat plate shape and fitted to the outer periphery except the lower end. When fitting the upper container A and the lower container B, the lower end portion of the sealing plate 18A may be inserted into the concave groove of the fitting portion 8 so that the entire periphery of the sealing plate 18A is in the closed state. Normally, when the head pressure is applied with such a simple fitting structure, the stored water usually flows out. However, in claim 1, the on-off valve 6 is in a closed state, and in claim 2, the water injection port 4 is sealed with a sealing plug 16. In the sealed state, when water in the water storage tank Y tries to fall, a negative pressure is applied to the fitting surface of the concave groove 18B with respect to the atmospheric pressure due to the head pressure of the stored water, and the air outside the flower pot is forced to fall on the fitting surface. Attempts to penetrate through water tank Y. At this time, since the water which is going to enter the water storage tank Y can be blocked by the water film due to the surface tension acting on the fitting surface, it is possible to prevent the water from flowing out of the water storage tank Y. However, when the height of the liquid level inspection window 18 increases and the difference in head pressure between the upper end and the lower end of the liquid level inspection window 18 becomes larger than the above-mentioned surface tension, air is stored in the concave groove 18B at the upper end of the liquid level inspection window 18. The water enters the tank Y, and the stored water corresponding to the volume of the bubble that has entered flows out. If the height of the liquid level inspection window 18 is about 5 cm, the stored water will not easily flow out even if a slight gap is generated in the fitting surface of the concave groove 18B. It is normal that the degree of fitting of the concave groove 18B decreases over time. If a slight hanging wall 18E is provided in the cutout inside the outer cylinder 2 at the upper end of the concave groove 18B, even if the sealing plate 18A is slightly distorted, water can be stored. A safe structure without spills is obtained.

The colored plate 18C is 1 m on the back surface of the sealing plate 18A.
It is fixed to the fixing portion 18D at a position where a gap of m or more is provided. The color of the colored plate 18C may be arbitrary, and
For A, a translucent resin plate is more suitable than a transparent one. This is because when there is no water storage in the water storage tank Y, the color of the colored plate 18C cannot be clearly seen due to the irregular reflection of the sealing plate 18A.
If water is present in the gap between the sealing plate 18A and the coloring plate 18C, irregular reflection on the back surface of the sealing plate 18A is reduced, and the coloring plate 18C can be easily visually observed from outside the flowerpot,
The presence or absence of water storage can be clearly confirmed, and it has been found that the added value of the flowerpot is greatly improved compared to the liquid level inspection window of Japanese Patent Application No. 8-21753.

(Explanation of Principle) FIGS. 17 and 18 are schematic views for explaining the principle according to the first aspect, and will be described with an example in which the on-off valve 6 of FIG. 4 is adopted. 1. When the protrusion 6F is lifted upward to inject the water with the on-off valve 6 in the open state, the water flows upward through the on-off valve 6 while exhausting the air in the water storage tank Y to the outside, and at the same time, a small amount of water is discharged. Bottom water storage tank Z through narrow water passage 9
Flow into 2. In the open state at the time of completion of the water injection, the upper surface of the liquid in the water storage tank Y and the water injection cylinder 5 is at the atmospheric pressure, and both are in communication with each other through the water inlet 5C, so that both liquid levels are equal. In addition, since the head pressure of both liquid levels is applied to the water passage 9, the water in the water storage tank Y is poured from the water passage 9 into the bottom water tank Z, and the liquid level in the bottom water tank Z is gradually raised. 3. When water injection is completed, the protrusion 6F is pushed down to close the valve, and in this state, if the liquid level in the water storage tank Y attempts to drop, the gas phase pressure in the upper part of the water storage tank Y becomes reduced with respect to the atmospheric pressure. The head pressure applied to the fitting portions 7 and 8 at the lower end of Y changes from a pressurized state to a negative pressure state, and a pressure is applied to prevent water from flowing out from the lower end of the water storage tank Y. 4. The upper surface of the liquid surface in the water injection cylinder 5 and the upper surface of the liquid surface in the bottom water storage tank Z are equal at atmospheric pressure, and both liquid surfaces are in communication with each other through the water passage 9. The liquid flows into the bottom water storage tank Z having a low surface level, and the liquid level in the bottom water storage tank Z is raised slightly. 5. When the liquid level in the bottom water tank Z is lower than the lower end of the water injection cylinder 5, when water in the water injection cylinder 5 tries to flow to the lower water tank Z, a hemispherical water film is formed at the lower end of the water injection cylinder 5 due to surface tension. However, when the head difference between the two liquid surfaces is larger than the surface tension of the water film, the hemispherical water film swells further more, and finally the water film breaks and becomes bubbles and rises in the water tank Y. The liquid level in the water storage tank Y is lowered by the volume of the bubbles. The water in the water storage tank Y that has fallen passes through the water passage 9 to raise the liquid level in the bottom water storage tank Z. While repeating this phenomenon several times, when the liquid level in the bottom water storage tank Z becomes equal to the position of the lower surface of the hemispherical water film formed at the lower end of the water injection cylinder 5, the water film breaks,
The flow of water from the water storage tank Y to the bottom water storage tank Z is stopped, and a constant liquid level is formed in the bottom water storage tank Z at a position lower than the lower end position of the water injection cylinder 5 by the surface tension of the water film. For this reason, the constant liquid level formed in the bottom water storage tank Z is slightly lower than the lower end of the water injection cylinder 5, but becomes a constant liquid level based on the lower end position of the water injection cylinder 5. 6. The constant liquid level configured in the bottom water tank Z is about 0.5 to 3
cm or less, and the upper surface of the liquid level of the bottom reservoir Z is at atmospheric pressure. Therefore, the head pressure of the constant liquid level is applied to the fitting portion 8 through the water passage 9. If the outer peripheral wall 13 is set higher than the lower end position of the water injection cylinder 5 which is a reference for forming the constant liquid level, the liquid overflows to the outside even if poor airtightness or a gap occurs in the fitting portion 8 at the lower end of the outer cylinder 2 during use. There is no safety structure. 7. When the airtightness of the fitting portion 8 at the lower end of the outer cylinder 2 can be made high, the outer peripheral wall 13 may be set lower than the lower end position of the water injection cylinder 5. However, flowerpots are often installed under direct sunlight, the sealing degree of the fitting portion 8 decreases over time, and when the upper container A and the lower container B are fitted, fine soil is formed on the fitting surface. However, if the outer peripheral wall 13 is set in accordance with the item 6, airtightness cannot be obtained if it is sandwiched. B. FIGS. 19 and 20 are schematic views for explaining the principle according to the second embodiment, and will be described with an example in which a through-hole 17A penetrating the inner cylinder 1 slightly above the lower end of the inner cylinder 1 from left to right is employed. 1. When the sealing stopper 16 is removed from the water injection port 4 and water is injected into the water storage tank Y, the air in the water storage tank Y is exhausted from the water injection port 4 instead of the water injection, and a small amount of water is stored in the bottom water through the through-hole 17A and the water passage 9. The liquid flows into the tank Z to raise the liquid level in the bottom water tank Z. It is preferable that the flow rate into the bottom water storage tank Z is reduced as much as possible through the through-hole 17A and the water passage 9 so that the water in the bottom water storage tank Z does not overflow from the upper end of the ventilation tube 11 by the time of completion of the water injection. However, this does not apply to outdoor use and a combined use of a saucer, as overflow can be tolerated. 2. When the water inlet 4 is sealed with the sealing plug 16, the through hole 17A
Both of the water passage 9 and the water passage 9 have a negative pressure with respect to the atmospheric pressure. However, a head difference is generated between the through hole 17A and the water passage 9 due to a height difference, and as shown in FIG. An attempt is made to suck outside air into the water storage tank Y from the through hole 17A. At this time, a fine hemispherical water film is formed on the water storage tank Y side of the through-hole 17A due to surface tension, and a pressure is applied to prevent intrusion of air. If the head difference between the liquid level in the bottom water tank Z and the through-hole 17A is larger than the surface tension of the water film, the hemispherical water film breaks into bubbles and rises in the water tank Y. The volume of stored water flows into the bottom water storage tank Z through the water passage 9 to raise the liquid level of the bottom water storage tank Z. 3. While the above-mentioned phenomenon is repeated several times, the liquid level in the bottom water storage tank Z gradually rises, and from the water storage tank Y at a position where the surface tension of the water film due to the head difference from the through hole 17A becomes equal. The flow of water into the bottom reservoir Z stops. 4. Although the surface tension of the through-hole 17A is slightly different depending on the shape of the through-hole 17A, when the diameter of the through-hole 17A is 3 mm,
Surface tension is about 3 to 8 mm by head difference and 8 to 1 at 2 mm
It is about 5 mm, and the constant liquid level appearing in the bottom water storage tank Z is a position lower than the position of the through-hole 17A by the value described above. 5. The same principle is applied to the case where the slit 17 is formed in the through-hole 17A, and the constant liquid level which appears in the bottom water storage tank Z changes according to the width and height of the slit 17. For example, when the width of the slit 17 is 2 mm, the constant liquid level is 2 to 5 from the upper end of the slit 17.
mm, 10 to 20m when slit width is 0.5
m lower.

【The invention's effect】

1. Compared to Japanese Patent Application No. Hei 8-21753, the structure is simple because there is no water injection pipe 5 or exhaust pipe in the water storage tank Y. When transparent material is used for the upper container A, there is no obstructive object in the water storage tank Y. The beauty as a flower pot can be improved and the stacking can be dense. 2. Since the water storage tank is provided on the outer periphery of the flowerpot, the amount of water storage can be greatly increased. 3. Since the liquid level of the water storage tank changes from the upper end to the lower end of the flowerpot, it is easy to check the liquid level, and an unconventional appearance can be provided. 4. Since a constant liquid surface is formed on the upper surface of the bottom water storage tank Z, the amount of water supplied to the soil is constant. 5. Since the water storage is separated from the bottom water storage tank Z by the narrow water passage 9, the water in the water storage tank during use is less turbid, and a clean appearance can always be provided. 6. Even if the fitting degree of the fitting part is reduced, there is no fear of overflow. 7. Ventilation and drainage can be performed in the same way as conventional flower pots. 8. The upper container and the lower container can be easily separated, and the inside of the water tank can be easily cleaned. 9. Even if an opaque material is used for the upper container, the liquid level in the water storage tank can be easily checked by providing a liquid level check window. 10. A structure is possible in which the level of the constant liquid level in the bottom water tank Z can be adjusted from outside the flowerpot.
