Description

[Detailed description of the invention] [Field of industrial application] This invention relates to the improvement of flowerpots suitable for growing trees in environments where they are left alone for long periods of time and are exposed to severe temperature changes, such as on streets. It is something.

[Conventional technology]

The basic prior art related to the structure of the street flower pot of this invention is
-Patent No. 35082 (Method for preventing plant roots)
There is number 1050930.

That is, this is a method for preventing rooting of plants, which is characterized in that a plate-shaped body of soft polyurethane foam made of open cells is provided along the inner surface of a plant growing pot, and the inside is filled with soil to grow the plants.

In addition, as a plant cultivation container,
Publication No. 14919 is disclosed.

This container, as stated in the registered claims,
``As shown in the drawings and description, along the inner surface of the flowerpot 1, there is a partition wall 3 that is water-resistant, corrosion-resistant, and has a large number of seepage holes, and the inner wall surface and bottom surface are made of rock wool or other porous material for adsorption. Structure of a plant cultivation container provided with layer 5.''

In summary, this container has an adsorption layer that accumulates moisture such as asbestos on the inner surface of the pot, and a partition wall made of vinyl chloride or the like that has a large number of seepage holes on the inside of the adsorption layer.
The idea is to gradually supply it to the soil from an adsorption layer. Therefore, the partition wall and the adsorption layer that retains moisture for a long time act as an air barrier, and there is no risk of a lack of supplied moisture, but the intake of oxygen from the air will be insufficient, and roots will form on the inner surface of the partition wall. It has the potential to cause rot, and changes in temperature can cause stuffiness and freezing.

Furthermore, Japanese Utility Model Publication No. 36-5557 discloses a viscose sponge body for use in plant pots.

In this example, as stated in the registered claims, ``As shown in the drawing, a viscose sponge made by foaming and regenerating viscose or viscose mixed with appropriate auxiliary materials is used as a soil substitute inside a flower pot. A structure of a viscose sponge body for a flower pot, which comprises a sponge body 2 formed into an appropriate shape, and a hollow part 4 into which a cylinder 3 is fitted, provided in the center thereof.

That is, the entire volume of the flowerpot is filled with viscose sponge without using soil.
In particular, viscose sponge is hard and has the characteristic of becoming soft only when it absorbs water and returning to its original hardness when dry.It is nearly impossible to grow plants in dry conditions, and it is constantly over-humidified. There is no choice but to make it a state of affairs. If such a block body is used with other sponges as well, if the sponge has open cells, the larger the unit volume, the greater the air circulation, resulting in premature drying and poor root growth. Otherwise, it will lead to withering and death. In the case of viscose sponge, since it is hard, it has an additional cause of defects.

In the case of such block sponges, the entire surface area forms a rapid evaporation surface, so if you try to keep the upper part at a constant level of humidity, the middle and lower parts will inevitably become overhumidified. This results in root rot or lack of air, which causes root rot at the contact point between the sponge block and the inside of the pot. In addition, if an attempt is made to prevent over-humidity, it will result in excessive dryness, and if it is too dry, root growth will be poor and even death will result, making it almost impossible to control the situation.

[Problem that the invention attempts to solve]

This idea aims to plant and grow trees in portable pots instead of planting them on the ground.
Street flower pots are likely to be left in a limited area for a long period of time and are exposed to severe temperature changes, so in addition to conventional measures to prevent the roots from growing, more advanced measures must be taken to insulate and prevent stuffiness due to temperature changes. Measures to prevent freezing, over-humidity, over-drying,
Regardless of rain or shine, it is possible to supplementally introduce sufficient air supply to the foam without any change, and
There is a need for a pot that has all the necessary features to prevent aging of the foam and prevent direct introduction of rainwater into the foam and air supply. In addition, the outer shell of the pot is relatively large and needs to be structured so that it can be easily moved.

This idea explores the problems mentioned above and aims to solve them.

[Means for solving problems]

Among the above-mentioned problems, first, as a measure to provide sufficient air supply necessary for root growth, to provide insulation due to higher temperature changes, and to prevent stuffiness and freezing, An air chamber and heat insulating section for introducing air is formed on the bottom, and sufficient insulation keeps the soil within the appropriate temperature range necessary for plant growth, while also allowing air to flow into the soft open-cell foam. Use as a supplementary introduction source. However, direct intrusion of rainwater into the heat insulating section causes undesirable factors such as blocking of air supply and overhumidity. Therefore, in order to cover the upper surface of the introduced air chamber, an overhang-like covering part is provided which also serves as reinforcement and covers the upper edge of the flower pot. This introduction air chamber is formed by providing a partition wall for configuring the introduction air chamber at a required interval on the inner circumferential surface of the side wall at the lower part of the overhanging covering part, or on the inner circumferential surface of the side wall and the entire bottom surface, and the partition wall A flexible open-cell polyurethane foam plate is provided on the inner peripheral surface of the foam plate, and a large number of communication holes for introducing air into the foam plate are formed in the partition wall. Note that the required interval between the introduction air chambers and the diameter and number of the communication holes in the partition wall are determined as appropriate, taking into account excessive humidity and excessive dryness, depending on the region with high or low rainfall and other environments. Further, the case where the area of the ventilation hole in the partition wall on the inner circumferential surface of the side wall and the partition wall on the bottom surface is approximately the same, but the area of the ventilation hole in the bottom surface is significantly increased, etc. is applied. In case of a tendency towards overhumidity, it is also possible to use net-like partitions with a vent area of 50% or more of the partition. In addition, in order to prevent the upper part of the foam plate-like body from being directly exposed to sunlight and wind and rain, the flowerpot for street use of this invention is constructed by forming the upper part of the foam plate below the overhanging covering part in the same manner as the introduction air chamber. It is something to do. The inside of this flower pot is filled with soil and plants are planted therein. The soil is filled below the level of the overhang-like covering to the extent that it does not hide the overhang-like covering. In addition, a handle is formed on the upper part of the inner surface of the pot so that it can be moved easily. That is, the structure is designed to form introduction air chambers at required intervals on the inner peripheral surface of the side wall of the pot below the overhang-like covering covering the upper edge of the flower pot, or on the inner peripheral surface and bottom surface of the side wall. A partition wall having communicating holes is provided, a plate-like body of soft open-cell polyurethane foam is provided on the inner peripheral surface of the partition wall, and a hanging handle is provided at the upper part of the inner surface of the pot, and the inside is filled with soil. This is a street flower pot used for street use. Furthermore, details will be explained based on the drawings of the embodiments.

The outer shell of the flowerpot is not particularly limited, and may be made of an inorganic material such as cement, a plastic material, or a composite material of these reinforcing materials and a foam material. The material of the partition wall is not particularly limited as long as it is hard enough to support the soil and is not harmful and can maintain its shape for a long period of time. Foam boards etc. are used. For example, spacing pieces corresponding to the spacing of the air chambers to be introduced are partially attached to a plate-like material such as hard polyurethane foam, styrofoam board, or polyvinyl chloride so that outside air can communicate with the inner peripheral surface of the side wall of a flowerpot. , or set on the inner peripheral surface and bottom surface. In addition, when using hard foam board, it also has a heat insulating effect, so
It is also possible to reduce the interval between the introduced air chambers, which is appropriate in cases of excessive dryness. In addition, since the hard foam board has a certain degree of flexibility, by using it in combination with a soft open-cell polyurethane foam board, a better expansion and contraction state can be obtained, and the contact surface with the soil , a better soil surface is formed. Therefore, the advantage of this invention is that it is easier to more effectively create a suitable natural reflux condition in which an appropriate temperature, appropriate dryness and humidity, and the necessary amount of air are constantly and uniformly supplied at the contact surface with the soil surface. be.

[Effect]

As mentioned above, in the flowerpot of this invention, the introduction air chamber is covered with an overhanging covering part around the upper edge, so rainfall does not directly enter the introduction air chamber and the open cell, so there is no possibility of overhumidity. A good air supply source is formed regardless of rain or shine, and good heat insulation properties can be exhibited. Therefore,
It can respond to severe temperature changes and prevents negative effects such as overheating, stuffiness, and freezing. In addition, like the introduced air chamber, the open-cell foam plate has its upper end held within an overhang-shaped covering around the upper end, and when in use, the lower part is buried in the soil, so it cannot be exposed to direct sunlight. and without exposure to the elements.
Good physical properties of the foam are maintained over a long period of time, and the soft foam expands and contracts well at the contact surface with the soil as the soil dries and wets, and the intake and exhaust of air into and out of the foam is achieved by setting the introduction air chamber. This maintains a good air permeability density of the soil at the contact surface and provides sufficient air replenishment, promoting good natural circulation through the soft open foam and spreading evenly over the entire height of the pot. , a suitable natural reflux state is created in which an appropriate temperature, appropriate dryness and humidity are formed, and the necessary amount of air is constantly and evenly supplied.

In particular, when a hard foam is used for the partition wall, the synergistic effect of the elastic flexibility of the hard foam and the soft foam provides a better condition and natural reflux condition at the contact surface with the soil.

As mentioned above, the internal functional structure formed on the inner surface of the pot of this invention, which consists of the introduced air chamber, the partition wall, the soft open-cell urethane foam board, etc., allows for a substantial amount of roots to be obtained through good root proliferation over a long period of time. It exerts the effect of growing vigorous plants.

FIG. 3 is a partially enlarged sectional view of the side wall of the same flower pot, showing the structure of the introduced air chamber, the partition wall, and the polyurethane foam plate.

FIG. 4 is a partially enlarged cross-sectional view of the hanging handle of the same flowerpot. The flowerpot having the internal functional configuration of this invention can be applied to pots of various shapes such as square, round, oval, and polygonal.

In the figure, 1 is the side wall of the pot, 2 is the bottom of the pot, 2
a is a reinforcing stay. Reference numeral 3 denotes an overhanging covering part that covers the upper edge of the flowerpot, and 4 a hanging handle, which is a plate-shaped projecting handle integrally formed on the upper inner surface of the side wall of the flowerpot. A hook hole 4a for hooking a shaped hook is provided. In addition to transporting pots, the handles are also used to attach hooks to tree support wires equipped with turnbuckles when it is necessary to support planted trees. For this square pot, the hanging handles are set at the four corners. In the case of a round shape, it is set in three equally divided locations. In addition, for convenience of movement, casters and casters with brakes are appropriately set on the outer bottom of the pot.

Next, insulating air chambers, partition walls, and foam plates are installed on the inner circumferential surface of the side wall of the lower part of the overhanging covering part of the flower pot having the above structure, or on the inner circumferential surface and the bottom surface, and serve as a supplementary air introduction source. The internal functional configuration of this invention, which consists of a shaped body, etc., will be explained.

Reference numeral 5 denotes introduction air chambers provided at required intervals on the inner circumferential surface of the side wall of the lower part of the overhanging covering part 3 of the pot, or on the inner circumferential surface and bottom surface of the side wall. This introduction air chamber is shown in the partially enlarged cross-sectional view of the side wall part in FIG.
As shown in the cross-sectional view of the figure, it is formed by setting the partition wall 6, and the partition wall 6 is partially provided with spacing pieces 7 corresponding to the required spacing for providing the introduction air chambers 5 at the required spacing. The introduction air chamber 5 is fixed to the partition wall 6 and the introduction air chamber 5 is connected to the polyurethane foam plate set inside the partition wall. A communication hole 8 is provided for this purpose. The diameter and number of the communicating holes 8 are appropriately determined in consideration of over-humidity and over-dryness depending on the environment of the setting area, the size of the pot, etc. Reference numeral 9 denotes a soft open-cell polyurethane foam plate adjacent to the inner circumferential surface of the partition wall having communication holes 8 . 10 is a foot portion of the flower pot, and 11 is a drainage hole.

The internal functional configuration of this invention is for use in larger pots than ordinary flower pots, and in the case of large flower pots, it is more preferable to set it on the inner peripheral surface of the side wall and the bottom surface, but in the case of relatively small pots, it is preferable to set it on the inner peripheral surface of the side wall and the bottom surface. A considerable effect can be obtained simply by setting it on the inner peripheral surface.

The internal functional configuration of the above invention can be applied to various flowerpots, and for example, by applying it to a flowerpot equipped with an irrigation pipe, the water supply pipe and the irrigation pipe of the flowerpot can be connected to a rubber hose, etc. If the valves are connected, irrigation operations can be performed very easily by opening and closing the valves, and together with proper irrigation, the internal functional configuration can be fully utilized.

Figures 5, 6, and 7 show examples of flower pots equipped with irrigation pipes.
A side view, FIG. 6 is a plan view in which a part of the internal functional structure of the bottom surface is cut out to expose a part of the inner bottom surface of the pot, and FIG. 7 is a sectional view taken along the line -- in FIG. 6. The internal functional configuration of this device is the same as the embodiments shown in Figures 1 to 4 above, and it can also be used as a flower pot with the exception of the legs being set at the four corners, and the structure is roughly the same except that the stay configuration is different. This is an example. In the figure, the irrigation pipe 12 has a socket 13 on the bottom surface 2 at a position closer to the center than the overhanging covering part 3.
The lower end has a connection part with a hose on the outside of the bottom surface, and the upper end is set above the filled soil or in the soil.

[Effect of idea]

Since the flower pot of this invention has the functions as described in the function section, it prevents negative effects such as overheating, stuffiness, and freezing, and maintains the soil temperature within an appropriate temperature range due to its insulation and heat retention effect. The setting allows for good natural circulation by supplying sufficient air to the soft open cells, which prevents the rooting phenomenon in street flower pots, grows a large amount of roots, and allows trees to be planted in the ground instead of planting them. This makes it possible to plant and grow trees well over a long period of time in a flower pot that can be easily moved.
