Detailed Description of the Invention

TECHNICAL FIELD The present invention relates to a garden pot (hereinafter referred to as a pot) for gardening.

[0002]

2. Description of the Related Art Commercially available pots are provided with a water tank at the bottom of the pot in order to extend the water supply period, and a non-woven fabric having good water absorption is hung from the bottom of the pot to make use of the capillary phenomenon. Water is being supplied to the soil at the bottom of the body. This water tank is mainly made of transparent material, so that the amount of liquid in the water tank can be confirmed and the management of the water supply condition to the plants is easy.

Although the pot is mainly used indoors, it can also be used outdoors, and even if a large amount of rainwater flows in from the upper part of the pot, a large amount of water is accidentally supplied from the upper part of the pot. Even so, the structure is such that the water can be easily drained from the ventilation port / drain port provided at the bottom of the bowl. The drained water is once stored in the water storage tank, and the excess water overflows from the water storage tank.

Therefore, in this pot, the soil at the bottom of the pot does not become liquid-tight, and fresh air can be sucked from the ventilation port at the bottom of the pot, so that the root of the plant does not rot. However, since the bowl has a water inlet at the fitting portion between the bottom of the bowl and the upper end of the water tank, it is necessary to incline the bowl for water supply. In addition, since the water inlet has a small space because it is provided on the fitting surface, there is a drawback that the floor surface is contaminated by overflow when pouring water. Since the bowl is also an ornamental product, if the water tank at the bottom of the bowl is made large or set high, aesthetic problems occur, so the capacity of the water tank is naturally limited.

However, the application number, Japanese Patent Application No. 6-25595
In the pot body introduced in 8, the outer peripheral wall of the pot body is composed of a double tubular body, and the hollow portion formed between the two tubular bodies serves as a water storage tank, so that the appearance of the pot body becomes the conventional pot body. It is now possible to increase the amount of water storage to about 3 times that of conventional bowls with water storage tanks without significantly changing it. However, since this bowl was for indoor use only,
In order to prevent overflow, the bottom of the pot is hermetically sealed, and therefore ventilation is inhaled through the soil above the pot to the root of the plant, resulting in insufficient ventilation. It was also found that if a large amount of water was accidentally poured directly into the plant from the top of the pot rather than the water inlet, water would accumulate at the bottom of the pot, making the soil liquid-tight and causing root rot.

Further, in the pot body introduced in Japanese Patent Application No. 6-255959, when the pot body is directly filled with soil, the soil enters the incision to be described later, which hinders air replacement and the water in the water storage portion is the bottom water tank. There was a scene where it did not leak to.

[0007]

The present invention is directed to Japanese Patent Application No. 6-2.
Compensating for the drawbacks of 55958, a constant liquid surface water tank is constructed at the bottom of the pot, and at the same time, a drainage port and a vent are provided at the bottom wall of the pot to prevent root rot in both indoor and outdoor use. Even if the bowl is made of transparent or opaque material, the liquid level in the water storage part can be controlled.

FIGS. 9, 10, and 11 show an embodiment according to claim 5, wherein when an opaque material is used for both containers A and B, the presence or absence of water in the hollow portion Y which is a water storage portion I cannot confirm. In order to solve the main problem, a part of the vicinity of the outer peripheral wall 9 and the outer cylinder 2 of claim 1 is enlarged to form a concave tank, which is referred to as a liquid level inspection tank 10. If this and the hollow portion Z, which is the bottom water storage tank, are connected by a tunnel-shaped horizontal cylinder 6F, the hollow portion Z
The liquid level inside the liquid level inspection tank 10 becomes an equal liquid level, and the liquid level state in the hollow portion Z can be confirmed. As will be described in detail in principle, the hollow portion Z forms a constant liquid level as long as water is present in the hollow portion Y. Therefore, by checking the presence or absence of water in the liquid level inspection tank 10, the hollow portion Z You can judge the presence or absence of water inside.

In the fifth aspect, the inlet of the horizontal cylinder 6F on the side of the hollow portion Z is a cutout 7, and the side of the liquid level inspection tank 10 is an external cutout 7B.

With this configuration, the higher level of the upper end of the cutout 7 or the external cutout 7B serves as a reference for forming the constant liquid level on the constant liquid surface appearing in the liquid level inspection tank 10.

In FIG. 9, the cutout 7 is the outer cutout 7B.
Since the upper end is higher, the upper end wall 7 of the cutout 7
The position of A serves as a reference for the constant liquid level. Further, the exhaust pipe 6 may have a structure in which a pipe-shaped tubular body is inserted into the fitting pipe 6F. By providing the horizontal cylinder 6F as described above, the exhaust pipe 6 can be easily fixed, and the cutout 7 and the exhaust pipe 6 can be easily joined. This configuration is effective for large tall bowls. In addition, in the case of a short bowl, it is better to integrally configure the exhaust cylinder 6 and the horizontal cylinder 6F.

FIGS. 12 and 13 show an embodiment according to claim 6, and in claim 5, when an opaque material is used for the upper container A, only the presence or absence of water in the hollow portion Y can be confirmed. According to the sixth aspect of the present invention, even if an opaque material is used for the upper container A, the liquid surface state in the hollow portion Y can be continuously displayed. As shown in FIG. 12, the hollow portion Y
The exhaust pipe 6 provided inside is provided close to the upper and lower sides of the outer wall surface of the outer pipe 2, the upper end portion of the exhaust pipe 6 is hermetically sealed, and a cylindrical fitting convex portion 6H is provided on the upper end side portion.

Further, when a fitting recess 2A penetrating left and right is provided in the upper end side wall portion of the outer cylinder 2 and the fitting recess 2A is fitted with the fitting recess 6H, a hollow portion Y and a hollow portion in the exhaust pipe 6 are formed. Allows communication through the hollow portion in the fitting portion. Further, since the lower end of the exhaust cylinder 6 is inserted into the liquid level inspection tank 10 and the lower end opening of the exhaust cylinder 6 plays the same role as the cutout 7, the lower end of the exhaust cylinder 6 serves as a standard for forming a constant liquid level. . The horizontal cylinder 6F according to claim 5, between the liquid level inspection tank 10 and the hollow portion Z.
There is a communication pipe 6I having the same structure as described above so that the liquid level inspecting tank 10 and the liquid level in the hollow portion Z become equal. Communication pipe 6I
Like the horizontal cylinder 6F, the lower end is in close contact with the bottom wall 8, and the upper wall surface is provided with fitting portions 14D and 14E for the inner cylinder 1 and the outer cylinder 2. Therefore, the lower end of the hollow portion Y is in a sealed state, and the hollow portion Y is configured to communicate with the outside through the ventilation port 6A, the hollow portion in the exhaust pipe 6 and the liquid level inspection tank 10.

Since the upper space in the exhaust cylinder 6 and the upper space in the hollow portion Y are connected by the vent hole 6A, an equal pressure is obtained. As a result, the liquid surface in the hollow portion Y and the liquid surface in the exhaust cylinder 6 become equal, and the exhaust gas is discharged. When a transparent or translucent material is used for the cylinder 6, the hollow portion Y
A liquid surface state equal to the inner liquid surface can be observed. Although the exhaust pipe 6 in FIG. 12 is a tubular body, a band-shaped recessed groove is provided on the outer wall surface of the outer cylinder 2 from the fitting recess 2A to the lower end of the outer cylinder 2, and a transparent band-shaped cover is adhered to the groove.

FIGS. 14 and 15 show an embodiment according to claim 7, in which the soil intrusion prevention cover 15 and the cut-out opening 7 serving as a cut-in portion are removed. That is, the upper end wall 7A of the cut opening 7 is hung down to the upper surface of the bottom wall 8, and the narrow gap portion 7C close to the upper surface of the bottom wall 8 is changed to the cut opening 7. When the opening portion of the cut opening 7 is the narrow gap portion 7C shown in FIG. 14, it is impossible to replace air in the narrow gap portion, but the lower end of the water injection cylinder 5 (in FIG. 14, the partition wall 5B which constitutes the water injection cylinder 5 is formed. The water passage 5A at the lower end) serves as an air replacement port, and a constant liquid surface is formed in the hollow portion Z with this position as a reference. When the cutout 7 is formed in the narrow gap portion 7C in this manner, it is possible to prevent soil from entering the exhaust pipe 6, and it is not necessary to particularly provide the soil intrusion cover 15. Note that this configuration can be applied to all pots according to the present invention as described in detail in principle.

FIGS. 16 and 17 show an embodiment according to claim 8 in which the cylindrical water injection cylinder 5 provided in the hollow portion Y is provided close to the outer wall surface of the outer cylinder 2, The upper end opening of the water cylinder 5 is used as the water injection port 4, and the lower end is fitted to the fitting cylinder 2B integrally formed with the lower end of the outer cylinder 2. The fitting cylinder 2B has a concave shape, and the hollow portion inside the fitting cylinder 2B penetrates the wall portion of the outer cylinder 2 and communicates with the lower end of the hollow portion Y. This penetrating portion becomes the water passage port 5A.

In FIG. 16, the water injection cylinder 5 and the fitting cylinder 2B are detachable so that the water injection cylinder 5 becomes an obstacle when the upper containers A are stacked in stock. By separating them, they can be stacked and the storage space can be made efficient. Further, by providing the water injection cylinder 5 outside the outer cylinder 2, the water injection port 4 can be designed large as shown in FIG. 17 to facilitate water injection. Further, the water injection cylinder 5 can be detachable because the liquid level in the water injection cylinder 5 is lower than the upper end of the fitting portion 2B during use even if the degree of adhesion of the fitting portion is reduced. No more spills.

According to a ninth aspect, the water injection cylinder 5 is integrally formed on the outer wall surface of the outer cylinder 2, and the hollow portion inside the water injection cylinder 5 penetrates the lower end wall portion of the outer cylinder 2 and can communicate with the inside of the hollow portion Y. When the storage space is not a problem, if the water injection cylinder 5 is integrally formed with the outer cylinder 2, an inexpensive pot body having excellent strength can be obtained. FIG. 16 shows an embodiment according to claim 10, and even if a small amount of water is poured from the upper part of the hollow portion X, in claims 1 to 9, water is dripped from the small hole 13 at the upper end of the cylindrical convex portion 11. Then, water seeps out from the gap between the upper surface of the pedestal and the lower end of the pedestal 16. Also, when water is sprinkled from the upper part of the bowl, drops may be dropped for a long time, and the floor surface may become dirty when the bowl is moved. The pot body according to claim 10 is intended to prevent this phenomenon. The soil prevention cover 15 and the flat plate portion 12 at the upper end of the cylindrical convex portion 11 of claim 1 are removed to vertically penetrate the cylindrical convex portion 11. It is made into a tubular shape. Cylindrical protrusion 11
A horizontal partition plate 18 is arranged at a position where a gap required for ventilation is provided at an upper end portion of the
1. A hanging wall 18A which can be in contact with the upper end portion while leaving a constant gap is provided. Further, an opening 18B is provided in an arbitrary portion of the partition plate other than the hanging wall 18A, and the tubular body 18C is hung down from the opening 18B to a position in contact with the bottom wall 8 so that the remaining partition plate flat portion can be easily soiled. A slit or small hole 18D that penetrates vertically so as not to fall is provided. As a result, even if the water contained in the soil in the hollow portion X drips, water can be stored in the hollow portion Z, and ventilation is performed by the hollow portion in the cylindrical convex portion 11, the gap between the hanging wall 18A and the cylindrical convex portion 11, and the partition. It becomes possible to pass through the small hole 18D of the plate 18.

When a large amount of water is supplied to the upper portion of the hollow portion X, it is drained through the cylindrical convex portion 11. Further, the hollow portion X is filled with soil, and even if the soil falls through the small holes 18, it does not fall on the floor surface. If the partition plate 18 of this configuration is adopted in this way, it is not necessary to use a saucer together, and this configuration can be applied to all of the above-mentioned bowls. In the present invention, the partition plate 18 is integrated with the inner cylinder 1, but may be separated. FIG. 17 is an example of the top view of FIG. 16 in which the position of the cylindrical convex portion 11 serving as ventilation and drainage channels is arranged in the center of the bottom wall 8.

FIG. 18 shows another embodiment according to the tenth aspect of the present invention in which the cylindrical convex portion 11 is arranged at a position close to the fitting portion 14A and the opening portion 18B is arranged at the center of the bottom wall 8. Then
Water is supplied from the central bottom opening 18B, and ventilation and drainage are performed from the cylindrical projection 11 provided on the outer periphery of the hollow Z. 18 and 19 are examples in which the partition plate 18 is adopted in FIG.

The liquid level inspection window 19 shown in FIG. 14 is an embodiment according to claim 11, and when the upper container A is made of an opaque material, the liquid level inspection tank 10 is provided so that the inside of the hollow portion Y is closed. It is possible to confirm the presence or absence of water storage, but it is not possible to confirm the continuous change in water level on the water storage surface. It is also conceivable that the liquid level inspection tank 10 may protrude from the outer wall surface of the bowl outer cylinder 2 to deteriorate the aesthetic appearance of the bowl, which is an ornament. In this case, a slit-shaped notch 19A is formed at the lower end of the outer cylinder 2, and a transparent or semitransparent sealing plate 19B is closely fitted to this. Various methods are conceivable for this fitting method, but the sealing plate 19B
Is provided with a concave fitting groove on the outer peripheral portion other than the lower end fitting portion, is inserted from below the notch portion 19A, and is closely fitted to the wall surface of the notch portion 19A outer periphery, and the lower end of the sealing plate 19B is the upper container. When the A and the lower container B are fitted, the fitting portion 14 at the lower end of the outer cylinder 2
It has a structure that can be fitted to B.

In addition, as the liquid level inspection window 19, an opening penetrating an arbitrary wall portion of the outer cylinder 2 may be provided, and the opening may be sealed with a transparent sealing plate. Even if the degree of fitting between the notch portion 19A and the sealing plate 19B is slightly reduced, air cannot enter the hollow portion Y through the fitting portion due to the surface tension at the fitting portion. The stored water never flows out.

[Explanation of Principle] FIGS. 20, 21 and 22 are explanatory views of the principle according to the present invention and are schematic representations of the embodiment of FIG. When water is injected from the water injection port 4, the water falls in the water injection cylinder 5 and flows into the hollow portion Y from the water passage port 5A. As the liquid level in the hollow portion Y rises, the air in the hollow portion Y is exhausted to the outside through the ventilation holes 6A, the hollow passages in the exhaust cylinder 6, and the cut openings through the soil in the hollow portions Z and X. The water that has flowed into the hollow portion Y is stored in the hollow portion Y and is a bottom water tank through the fitting surface between the cutout 7 and the exhaust pipe 6 and the narrow gap surfaces of the fitting portions at various places due to the head pressure L1. It oozes into the hollow portion Z. FIG. 20 shows this state.

When the water injection is further continued, the liquid surface of the hollow portion Y reaches the upper end position of the water injection port 4, and the time when the water injection is completed can be known by confirming the full state of the water injection port 4.
When a transparent material is used for the upper container A, the liquid level state of the hollow portion Y can be visually confirmed through the wall portion of the outer cylinder 2, so that the water stopping timing can be easily determined. This state is shown in FIG. In this state, the gas phase pressure in the upper part of the water storage surface in the hollow portion Y is atmospheric pressure through the exhaust cylinder 6, and the upper part of the liquid surface in the water injection cylinder 5 is also atmospheric pressure. Since the hollow portion Y has a communication tubular shape through the water passage port 5A, both liquid surfaces are equal. In this state, since the atmospheric pressure is applied to both the water storage surface in the hollow portion Y and the liquid surface in the hollow portion Z, the water head difference L2 between the both liquid surfaces is applied to the fitting portion, and this difference pressure causes the fitting portion narrow gap surface. Water oozes out from the liquid and raises the liquid level in the hollow portion Z.

When the liquid surface in the hollow portion Z reaches the upper wall 7A of the cut opening, the cut opening 7 is sealed with water. In this state, since the head pressure L3 shown in FIG. 22 is continuously applied to the fitting portion, the water in the hollow portion Y continuously bleeds out into the hollow portion Z, and the water storage surface in the hollow portion Y is lowered. Let However, at this point, the gas phase above the water storage surface is in a sealed state,
Due to the decrease of the water storage surface, the gas phase becomes depressurized and the hollow part Z
Of water is sucked up into the exhaust pipe 6, and when the water storage surface in the hollow portion Y becomes equal to the liquid surface in the exhaust pipe, the bleeding of water from the fitting portions stops at various places. The water level at which the water storage surface drops in this transient state is a little because the volume of the exhaust pipe 6 is small. Hollow part Z
The water inside and the water inside the water injection cylinder 5 are in the form of a communicating tube through a narrow gap in the fitting portion, and the upper surfaces of both liquid surfaces are at atmospheric pressure, so they are equal in a stable state.

When the liquid level in the hollow portion Z is lowered by the water supply such as a plant, the water film in the cut opening 7 which was in a water-sealed state is broken, the water in the exhaust pipe 6 is replaced with air and falls, and the hollow portion Y The gas phase inside passes through the exhaust pipe 6 and becomes atmospheric pressure. In this case, as shown in FIG. 21, the head pressure is applied to the fitting portion, water seeps out from the fitting portion, the liquid level in the hollow portion Z rises, and the state shifts to the state shown in FIG. Thus, the liquid level in the hollow portion Z is
While the water is stored therein, a constant liquid surface is formed with reference to the upper wall 7A of the incision, and the soil in the hollow portion Z is in contact with the constant liquid surface by the capillarity of the soil in the hollow portion X. Provide stable water supply. This water supply amount is constant regardless of the remaining amount of water stored in the hollow portion Y. When the bowl of the present invention is designed, the cutout 7 and the hollow passage cross-sectional area in the exhaust pipe 6 must have a predetermined area or more for air replacement, and the shape of the cutout 7 also varies. For this reason, when soil enters the incision 7, the area of the opening is reduced and air replacement is impossible, so the soil intrusion prevention cover 15 is provided.

The above-described operation is performed when the cutout upper end wall 7A is higher than the lower end of the water injection cylinder 5, and when the lower end position of the water injection cylinder 5 is higher than the cutout upper end wall 7A, the hollow portion The constant liquid surface formed in Z is based on the position of the lower end of the water injection cylinder 5. In this operation, when water is injected from the water injection port 4 as shown in FIG. 23, the water falls in the water injection cylinder 5 and flows into the hollow portion Y, and the air in the hollow portion Y is sucked into the lower end narrow space of the exhaust tube 6. The air is evacuated from 7C, and at the same time, the water head pressure M1 in the hollow portion Y causes water to seep out from the fitting portion. This state shows the liquid surface of M1 in FIG.

When water injection is further continued, the liquid level in the hollow portion Y becomes equal to the liquid level in the water injection port 4, and the timing of stopping water can be determined. This state shows the liquid surface of M2. Immediately after the water injection is stopped, since the vapor phase portion above the hollow portion Y is at atmospheric pressure, water tends to ooze out continuously from the fitting portion due to the water head difference M2, but the exhaust pipe 6 is in a water sealed state. The gas phase portion of the hollow portion Y is shielded from the atmosphere, and the liquid level in the hollow portion Y is lowered to reduce the pressure, so that water is sucked into the exhaust pipe 6 and becomes equal to the liquid level in the exhaust pipe 6. Stop. However, in this state, the water injection cylinder 5
Since a water head difference remains between the inner liquid surface and the inner liquid surface of the hollow portion Z, the liquid surface in the water injection cylinder 5 drops to the lower end of the water injection cylinder. In this state, if a water head difference from the liquid surface inside the hollow portion Z remains, a hemispherical water film M5 due to concave surface tension is formed at the lower end of the water injection cylinder 5.

When the water head difference is larger than the surface tension of the water film, the hemispherical water film is broken, and a volume of air M6 corresponding to the hemispherical surface floats in the hollow portion Y, and this amount of water is hollow. It flows out from the part Y to the hollow part Z, raises the liquid level in the hollow part Z, and until the water head difference between the liquid level in the hollow part Z and the lower end water film of the water injection pipe 5 disappears, the lower end opening of the water injection pipe 5 More hollow Y
Bubbles intermittently float inside. When the liquid surface in the hollow portion Z reaches the lower end position M7 of the hemispherical water film M5, a stable state is achieved.

When the lower end opening of the water supply cylinder 5 is used as the air replacement port as described above, the narrow gap portion 7C corresponding to the cut opening at the lower end of the exhaust cylinder 6 is used only for exhaust gas and water absorption, so that the soil does not enter. An opening may be used, and for this reason, it is not necessary to particularly provide the soil intrusion prevention cover 15 according to the first aspect. As described above, the constant liquid surface formed in the hollow portion Z becomes the upper end wall 7A of the cutout opening or the lower end of the water injection cylinder 5,
The upper ends of the cylindrical convex portion 11 and the outer peripheral wall 9 need to be provided at a position higher than the above. However, since a high water head pressure is applied to the fitting portions at various places only when water is injected, the fitting portion 14B at the lower end of the outer cylinder 2 is configured to have a high degree of sealing, and the inner cylinder 1 serving as a water inlet to the hollow portion Z is formed.
The lower end fitting portion 14A and the joint surface between the cutout 7 and the exhaust pipe 6 need to leave a small gap. However, the sealing degree of the fitting parts at various places is usually loosened due to deterioration over time, and if there is a concern that the floor surface will be polluted when pouring water, a saucer may be used together. In the stable state M7 after completion of water injection, in principle, water does not overflow from the pot during use even if the fitting part deteriorates.

EFFECTS OF THE INVENTION By providing the water storage portion on the outer peripheral portion of the pot body, the water storage amount can be increased by 3 to 4 times as compared with the conventional pot body in which the water storage portion is provided on the bottom portion of the pot body. It became possible to extend to. Since water is supplied to the soil inside the pot body from the constant liquid surface portion at the bottom of the pot body by utilizing the capillary action of the soil, a constant water supply is possible regardless of the remaining amount of water in the reservoir. By using a transparent or semi-transparent material for the upper container A of the bowl, the water storage surface can be determined at a glance, and the state of reducing the liquid from the top to the bottom of the bowl can be continuously observed, making it easy to determine the timing of water supply. it can. Since the pot body is composed of the removable upper container A and the lower container B, it is easy to clean and the pot body can always be kept clean.

Since the bottom of the bowl is provided with the same ventilation port and drainage port as the conventional bowl, the same handling as the conventional bowl can be performed. In addition, even if the fitting portion of the pot body deteriorates with age and the sealing degree of the fitting portion is lowered, this does not cause overflow liquid from the water storage portion during use. Thus, the pot of the present invention is superior in function and decoration as compared with the conventional pot. Also, if both containers are disassembled, it is possible to stack the containers and the stock space is significantly reduced.
