2. Description of the Related Art Heretofore, a flower pot has, for example, a seto pot or a plastic pot, or an outer pot, oriental orchid pot shape, plastic pot shape, vinyl pot shape or plastic pot shape, or deep pot, medium deep pot, shallow pot. Pots and other unglazed pots, red mud pots and vermicelli pots, seto pots or flat pots, flower pots such as dish pots are commercially available, and are used for growing and commercializing plants.
Made from unglazed, pottery and plastic materials. When a plant is grown using a flower pot, an appropriate amount of potting soil is put in the plant pot, a plant to be planted is planted in the potting pot, and the plant is grown by applying appropriate sunshine, temperature and humidity. It is said that the potting soil used for the plant pot is well drained, has good water retention and air permeability, and can well hold the fertilizer given thereto, and is also clean.

[0003]

However, the unglazed flower pot is relatively porous because it is not baked, and the wall has water permeability and air permeability, so that root rot is small, Moisture in the soil is easily lost, and unless watered relatively often, the plants in the flowerpots are prone to water withdrawal and cannot be left out for a relatively long time.
It is a problem. Further, since the pottery made of ceramics is baked in, it has poor air permeability and water permeability, is prone to root rot, and cannot add a large amount of water, which is a problem. Moreover, the unglazed and pottery flower pots are relatively heavy and easily cracked by the impact such as dropping, which makes them inconvenient to carry and poses a problem. On the other hand, the plastic flower pot is light and relatively flexible, and thus is less likely to be damaged by an impact such as a drop, which is convenient for transportation. However, because it is made of plastic, like the pots made of ceramics, the walls do not have air permeability, and as a result, water does not leak out from the wall of the pots, and compared to unglazed pots, water does not leak out. It has a long life, but the water in the medium remains in the flowerpot for a relatively long time,
This is a problem because the plant easily rots in the flowerpot because it easily rots. Further, a large amount of waste wood is generated from a construction site or the like, and even in a building material manufacturing plant, a large amount is generated as sawdust, cutting scraps, shavings, and the like when cutting or processing wood. Moreover, the waste wood from the construction site is contaminated with metal materials, wallpaper, etc., and its treatment is a problem. An object of the present invention is to solve the problems of watering and transportation of conventional plastic, pottery and unglazed flower pots, as well as the problems associated with the treatment of waste wood and plastic waste materials.

It is formed so that it can be bonded to the inclined portion 54 of 6. However, the outer convex portion 60 of the imaginary line 59 of the bottom wall second concave engagement piece 46 of the inclined portion 54 of the bottom wall second convex engagement piece 56.
The surface in contact with can be formed as a glue margin by applying a water-insoluble adhesive such as a hot melt adhesive. In this case, it is preferable that no adhesive is applied to the convex portion 60 on the outer side of the imaginary line 59 of the second concave engagement piece 46 of the bottom wall portion so that it cannot be used as a glue margin, but a hot melt adhesive is applied. It may be used as a glue margin. In this example, an adhesive margin portion is formed on the lower surface of the convex portion 61 on the side wall first fold line side of the bottom portion 39 of the bottom wall portion first concave engaging piece 42, and
An adhesive margin portion can be formed on the lower surface of the convex portion 52 on the side wall third fold line 8 side of the bottom portion 43 of the bottom wall portion second concave engagement piece 46. In this example, the bottom wall portion first concave engaging piece 42 and the bottom wall portion second concave engaging piece 46, when assembled, have the bottom wall portion first convex engaging piece 49 and the bottom wall portion first convex engaging piece 49. The drainage hole 25 is formed in a portion that does not overlap the bottom wall second convex engagement piece 56.

Since the assembly member of the flowerpot 1 of this example is constructed as described above, for example, the side wall first fold line 4, the side wall second fold line 6, the side wall third fold line 8 and the side wall fourth fold line are provided. The side wall portion first side portion 7, the side wall portion second side portion 9, the side wall portion third side portion 11, and the side wall portion fourth side portion 12 are formed by bending along each fold line in the order of 10.

EFFECT OF THE INVENTION The flowerpot and lid of the present invention are a mixture of pulverized waste wood and a water-absorbent resin mainly containing fibrous wood particles having a particle size of 4 mm or less, or fibrous wood particles having a particle size of 4 mm or less. A mixture of waste wood crushed mainly containing water, a mixture of water-absorbent resin, a waste material crushed mixture containing a mixture mainly containing a plastic substance particle having a particle size of 4 mm or less and a water-absorbent resin is used as a water-absorbent mixture, and water-absorbed mixture is used. Since it is formed by pressure-bonding water-absorbent paper on both sides of the organic mixture, waste materials can be effectively used, and moreover,
Since a water-impermeable and breathable plastic film is attached to the outside, it is difficult for water to pass through the walls of the flowerpot and lid,
The water that became excellent in water absorption and water retention and was irrigated and became excessive in the soil was absorbed and retained by the wall of the flower pot, and the water absorbed and retained by the wall of the flower pot was Water is sprayed onto the soil so that it does not reach a dry state, and the walls of the flowerpot and lid are breathable, so oxygen-dissolved water is retained through the air to prevent water spoilage in the flowerpot. Then, the damage such as root rot of the vegetated plant can be reduced, and it becomes possible to leave the plant for a long time with a single irrigation. Furthermore, in the present invention, since the waste wood pulverized product mainly containing fibrous wood particles having a particle size of 4 mm or less and the water absorbent resin are contained to form the water absorbent mixture layer of the flower pot, the moldability is excellent. It is possible to form the flowerpot main body portion and the lid portion which are excellent in water absorption and water retention.
