DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flowerpot made of rubber chips suitable for growing plants.

[0002]

2. Description of the Related Art
Flower pots include those made of unglazed and plastic.
Unglazed flower pots have excellent water permeability and air permeability and are suitable for plant cultivation, but have the disadvantages of poor water retention and fragility. In addition, plastic flower pots are easy to mold into various shapes, easy to decorate, light, hard to break, and inexpensive, but have poor water permeability and air permeability, so they are made of unbaked in terms of plant growth. Inferior to flowerpots.

[0003] On the other hand, if micropores are formed in a flowerpot made of plastic in order to impart water permeability and air permeability, the soil in the flowerpot tends to dry, which is not preferable in terms of plant growth. The present invention has been made in view of such circumstances, and its purpose is to be suitable for growing a plant, and is excellent in water retention, water permeability, air permeability, and hard to break, and It is to provide a relatively inexpensive flower pot.

[0004]

The flowerpot of the present invention is made of rubber.
The chips are hardened with a binder, and the rubber chips are
It is characterized in that the cellulose-based porous beads are dispersed . As the rubber chip, it is preferable to use a fibrous rubber chip. Further, the internal planting woodwasp, it is preferable that the reinforcement net is embedded.

[0005]

The flower pot of the present invention is formed by hardening rubber chips with a binder, so that air and water can pass through the gap between the rubber chips, and have water permeability and air permeability similar to unglazed flower pots. ing. On the other hand, the passage formed by the gap between the rubber chips is meandering unlike a normal through-hole, so that a certain amount of time is required for the passage of moisture.
Therefore, water can be retained to some extent in the flowerpot despite having water permeability and air permeability.

[0006] Further, by dispersing the cellulosic porous beads between the rubber chips, a part of the water that is going to pass between the rubber chips is retained in the porous beads,
The retained moisture is released gradually. In this way, the water retention is improved, and the soil in the flower pot can be prevented from drying out early. Further, since the flowerpot of the present invention is entirely made of rubber, it does not break, and is easy to mold and inexpensive, like plastic. Further, in a flower pot in which a reinforcing material is buried inside, stabilization in formality and strength is achieved.

[0007]

FIG. 1 is a schematic view showing the construction of a flowerpot according to an embodiment of the present invention. The whole flowerpot 1 is formed by solidifying a rubber chip 2 with a binder. The rubber chip 2 used in the present invention is a rubber molded product such as a used tire or the like obtained by pulverizing a waste material of a rubber molded product into a shape such as a scratch or a granule, or a rubber molded product powder generated by a buff performed after molding. The size and shape of the rubber chip are not particularly limited, but a fibrous rubber chip is preferable. Fibrous rubber chips are more granular than granular rubber chips.
This is because when the particles are hardened side by side in a random direction, the formed voids increase.

As the binder used in the present invention, a binder having a high affinity for a rubber chip, for example, a urethane-based, epoxy-based or rubber-based binder is used. This is because when a binder having a low affinity for the rubber chip is used, the binder more often enters the gap between the rubber chips than covers the surface of the rubber chip, which impairs the water permeability of the flowerpot. As for the amount of binder, the value of binder / rubber chip (weight ratio) is preferably about 5/100 to 30/100. The filling amount of the rubber chip may be appropriately selected according to the desired water permeability and strength, but generally the specific gravity is 0.4 to 0.5.
It is preferably about 95.

Since the flowerpot having the above-described structure is entirely made of rubber chips, it has excellent impact resistance, does not need to be broken like conventional pottery or unglazed flowerpots, and has a small space between the rubber chips 2. Since the gaps serve as passages for water and air, air permeability and water permeability can be exhibited. Figure 2 shows the porosity
FIG. 3 is a partially enlarged view showing an internal structure of the flowerpot 1 from which beads 6 are omitted . FIG. 3 shows that the porous beads 6 are placed between the rubber chips 2.
It is the elements on larger scale of the dispersed flower pot. FIG. 2 and FIG.
The arrows in FIG. 2 indicate the flow of water and air, and pass through the gap 5 between the rubber chips 2. In growing the plant, the root 4 of the root to be grown can enter the gap 5 between the rubber chips 2, and can absorb moisture existing between the rubber chips 2.

[0010] While some time in the gap 5 between the rubber chips 2 can retain moisture, in order to further improve the water holding capacity, by dispersing cellulosic porous beads 6 between the rubber tip 2 as shown in FIG. 3 I have . Here, the cellulosic porous beads 6 are porous particles mainly composed of a cellulosic polymer. An example of such porous beads 6 is Viscopearl (trade name) made of viscose made of cellulose as a main material manufactured by Rengo Co., Ltd. The particle diameter of the porous beads used in the present invention is 1.0 to 4.0 from the viewpoint of dispersibility between rubber chips.
mm is preferable. Then, from the viewpoint of water retention, the pore diameter is 10 ⁶ to 10 ⁴ Å, and the porosity is 70 to 95.
% Is preferable. Although the content of the porous beads varies depending on the specific gravity of the beads, the amount of the beads having a bulk specific gravity of 0.1 is preferably about 0.05 to 2% by weight based on the rubber chip. If the content is less than 0.05% by weight, the water retention effect of the beads cannot be obtained. If the content is more than 2% by weight, the gap 5 between the rubber chips 2 becomes relatively small, which causes a decrease in air permeability and water permeability. is there.

Such a porous bead 6 serves as a rubber chip 2
In the case of a flower pot dispersed between the rubber chips 2, the gap 5
A part of the water that is going to pass through is retained in the micropores 7 of the porous beads 6. The water retained in the hole 7 can be retained in the hole 7 because the material of the beads 6 is a cellulose-based material having many OH groups capable of hydrogen bonding with the water. On the other hand, since the cellulosic beads 6 do not have such a strong water holding power as compared with a polyacrylic acid-based superabsorbent polymer or the like, the water held in the pores 7 is accompanied by the drying of the soil or It is gradually released by the action of the hair root extending near the beads 6. As described above, the cellulosic porous beads 6 retain excess water, and then gradually release water to impart excellent water retention to the flowerpot. Therefore, the flower pot in which the porous beads 6 are dispersed between the rubber chips 2 has a sufficient air permeability, a gap capable of exhibiting water permeability, and also has a water retaining property necessary for growing the plant, and the soil can be quickly formed. Drying can be prevented. Further, it is also possible to make the micropores 7 of the porous beads 6 contain a fragrance, a fertilizer, and the like, whereby a highly functional flowerpot can be provided.

Further, in the flowerpot of the present invention, in order to improve the strength, it is preferable to embed a reinforcing material inside. By embedding reinforcing material for shape retention,
It is possible to increase the gap 5 between the rubber chips 2, and by using the rubber beads 2 together with the porous beads 6, air permeability, water permeability,
Further improvement in water retention can be achieved. As the reinforcing material, breathability inherent in a rubber chip-made flower pot,
It is preferable to use a net made of resin, metal, lath, or the like so that the water permeability or the like is not impaired and the strength can be sufficiently increased to maintain the shape. The shape of the reinforcing material may be the same as that of the flowerpot, or may be only a side portion that is susceptible to a lateral impact or the like, that is, a substantially cylindrical shape. FIG. 4 shows a flower pot in which a reinforcing material 9 having substantially the same shape as the flower pot is embedded, and FIG. 5 shows a flower pot in which the reinforcing material 9 is embedded only in the side portion.

Although there is no particular limitation on the method of manufacturing a flowerpot having the above-described configuration, a flowerpot having a reinforcing material can be easily prepared generally according to the procedure shown in FIG. First, a lower mold 10 having a concave portion matching the shape of a flower pot
Mixture of uncured binder and rubber chips 11a
(FIG. 6 (a)), and then a net-like reinforcing material 12 having substantially the same shape as the flowerpot is added, and further, a mixture b to which an uncured binder, rubber chips, and, if necessary, porous beads are added ( 6 (b), press-molding with the upper mold 13 (FIG. 6 (c)). With the curing of the binder, a flower pot containing the reinforcing material 12 formed into a predetermined shape is obtained.

By appropriately selecting a molding die, embossing or the like can be performed to meet the demand for decorativeness. The flower pot of the present invention is a concept that also includes a box-shaped planter. Further, the present invention is a flower pot for putting soil, but the present invention can also be used for a floor material or a wall material for causing plants to crawl on the surface. For example, new roots emerge from places without soil, such as potato plants, and in plants that grow there, hair roots enter the gaps between the rubber chips constituting the flooring or wall material, The plant is fixed to the floor or wall. Furthermore, since the floor material made of rubber chips is excellent in water retention, the hair roots can absorb the moisture held between the rubber chips, and thus are suitable for new growth of these plants.

FIG. 7 shows a state in which the plant 19 has taken root on the surface of the wall material 16 attached to the wall surface 15. Wall material 16
The rubber tip 18 is fixed with a binder, and the root 20 that has grown from the middle of the stem of the plant 19 enters the gap between the rubber tips 18, whereby the plant is fixed to the wall material 15.

[0016]

Since the flowerpot of the present invention is made of elastic rubber chips, it has excellent impact resistance and is hardly cracked. In addition, since the gap between the rubber chips serves as a passage for air and moisture, it is excellent in air permeability and water permeability. Furthermore, between the rubber chips, by this <br/> and which are dispersed the porous beads can be excellent water retention. Therefore, the flowerpot of the present invention can satisfy all the characteristics of air permeability, water permeability, and water retention required for plant growth.

Further, by embedding a reinforcing material inside, it is possible to cover a weak point due to the use of rubber.
