Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a pot container used for pot cultivation used for fruit tree cultivation, planting cultivation and the like.

[Prior Art] Conventionally, for example, in mandarin orange cultivation, it has been possible to grow a mandarin orange tree by installing a wooden container having a capacity of about 100, putting soil in the container, and planting seedlings in the container. It is being appreciated.

This is intended for early and uniform growth of fruit trees, but due to the efficient use of nutrients by using mixed soil used for pot containers and the good reason for water sweep, the growth rate of fruit trees is more than doubled, In addition, it has the effect of achieving uniform growth and quality.

On the other hand, when cultivating plants, etc., the saplings are grown to a certain level and transported to the customer when they are sold.
Repot. At this time, it takes a lot of time and labor to prevent the plant from dying during replanting, such as digging up the tree, cutting off the laterally spreading root, and once again filling it, and waiting until a thin hair root grows at the cut end.

Even in such a case, burying a container in the soil and planting seedlings in this container, and growing it while limiting the development of the lateral and vertical directions of the root does not require root cutting at the time of sale and is convenient for replanting. is there.

Traditionally, wooden bottomed boxes have been used for pot cultivation.

However, the wooden container has a drawback that the air permeability is not sufficient, the weight is large, and it takes a lot of time to carry and plant trees, and further, a large amount of wood is required for manufacturing the container, which is a trouble.

[Problems to be Solved by the Invention] An object of the present invention is to provide a container for pot cultivation in which pot cultivation is efficiently performed and tree planting work and manufacturing are easy.

[Means for Solving the Problems] The inventor of the present invention tried to utilize the fact that if a wooden container is made of a plastic non-woven fabric, the water scavenging property and the air permeability are excellent, and the weight saving can be achieved. Since the non-woven plastic container is so-called stiff, there is a drawback that the upper edge is bent during soil filling or tree planting work, making tree planting difficult,
At least two workers are required for the work because the upper edge of the container must be held upright.

The present inventor has found that the upper edge of the container falls, and a bag passage is formed on the upper edge, and if a hard plastic tape connected in a ring shape is passed through the bag passage, the upper edge can be easily self-supporting. The present invention has been completed based on this knowledge.

That is, the present invention provides a bag passage formed by folding back the edge of the nonwoven fabric and fixing it to the side surface at the upper edge of a bottomed container made of a cylindrical or prismatic synthetic fiber nonwoven fabric. The present invention also provides a pot cultivation container, characterized in that a continuous ring-shaped hard plastic tape having a self-supporting property of 20 cm or more is passed through.

The non-woven fabric used in the present invention is a non-woven fabric made of synthetic resin fiber, and for example, a non-woven fabric made of fibers such as polypropylene and polyester can be preferably used.

In addition to supporting the weight of the soil inside, this non-woven fabric may be carried with the soil in it, and it is necessary to have the strength to withstand the weight depending on the usage conditions. used.

For example, the weight per unit area of the fiber amount is 80 g / m ² or more,
Preferably, those having a thickness of 150 g / m ² or more can be suitably used.

The size of the container of the present invention is a container having a capacity of 30 or more, and is generally suitable for a container having a capacity of 80 or more, and has a bottomed prismatic or cylindrical shape.

The pot container of the present invention has a cylindrical shape or a prismatic shape, and a square prismatic shape having a square bottom surface is particularly suitable because it can be compactly folded.

The present invention will be described in more detail with reference to the drawings of the embodiments.

The pot cultivation container of the embodiment shown in the perspective view of FIG. 1 has a square bottom surface and a square side surface, and comprises a bottom surface and four side surfaces 1, 2, 3, 4 and these surfaces are Both are squares with a side length of 50 cm. Such a container having a square bottom surface and a side surface has a good balance of height and width when used as a pot container, and is convenient for transportation, packing and storage because it can be folded into a square shape of the same size.

The material of the container of this embodiment is a polypropylene non-woven fabric (Stratec, trade name, manufactured by Idemitsu Petrochemical Co., Ltd., weight 150).
g / m ² ) is used.

At the upper edge of the container, a bag passage 6 formed by folding back the cloth with a width of 3 cm and sewing the upper edge of the non-woven fabric to the side surface is formed, and the bag passage 6 has a cross section shown in FIG. A polypropylene tape 7 having a width of 2 cm and having a self-supporting property of 30 cm is passed through the bag passage.

The width of the bag passage is appropriately about 2 to 5 cm and can be selected according to the width of the tape to be put therein.

This hard tape is connected with one piece of tape over the entire circumference of the bag passage 6, and both ends are fixed with clips to form a ring. At this time. It is desirable to make the length of the ring-shaped tape slightly shorter than the length of the bag passage because the bag passage is slightly squeezed to increase the self-supporting property.

Usually, the hard plastic tape used in this invention is
Independence of 20 cm or more, preferably 30 cm or more,
A hard tape having a width of 1 to 3 cm and a thickness of about 0.2 to 1 mm, and for example, a tape having a strong and uneven surface used for packing can be used.

The self-supporting property of the tape used in the present invention is represented by the maximum length in which the tape is vertically held by holding the lower end of the tape, and the self-supporting property of the ring tape used in the present invention is 20 cm or more, preferably 30 cm or more. Need to use.

The greater the self-supporting property of the tape, the more desirable it is. If it is less than 20 cm, the self-supporting property of the container of the present invention is not sufficient.

The ring tape to be inserted into the bag passage of the present invention can be formed by passing a single tape through the bag passage and connecting both ends of the tape with clips or other fixing means.

In the present invention, the ring tape may be made of any material, for example, a thick tape such as high-density polyethylene or polypropylene, which is preferably provided with irregularities or grooves for self-supporting can do.

Thus, forming a bag passage in the upper edge of the non-woven container,
It is surprising that just passing a tape through it shows outstanding autonomy.

Further, the bag passage portion serves as a slip stopper when the soil is put in the pot and is lifted, which is also useful for improving workability.

When the container of the present invention is further increased in size, as shown in FIG. 3, in addition to the tape on the upper edge, a bag passage can be provided at the corner portion of the prismatic shape of the container to provide self-supporting property.

This bag passage can be formed by providing a seam allowance at the corner of the container and fixing both the corner portion and the seam allowance by sewing. Further, by putting a tape of 20 cm or more in the bag passage at each corner, it is possible to achieve complete bag self-supporting property.

[Operation] When a container having a capacity of 50 is simply made of a non-woven fabric, the edge of the container falls inside due to the weight of the cloth itself and cannot stand by itself.

If the bag passage of the present invention is provided in this, a certain amount of waist is generated at the upper edge of the container, and self-sustaining property is somewhat generated, but it is not sufficient. If you pass a hard tape through this passage and connect it to a ring,
The upper edge of the container is self-supporting without supporting it by hand. In addition, if the length of the tape is slightly shortened, the bag passage is narrowed, the waist becomes stronger, and the independence is increased.

When the container has a large capacity of 200, the self-supporting property may be deteriorated even by the above method.

In such a case, if the seam allowance is projected to the side surface as shown in Fig. 3, the corners have a three-dimensional structure, the self-supporting property is strengthened, and the tape tension and the action of the upper edge work well together. Be independent. Putting tape in this bag passage further increases independence.

The folding back of the bag passage at the upper edge of the present invention contributes to the non-slip when raising the soil-containing container and the improvement of the strength of the upper edge of the container.

By using a non-woven fabric as the material of the container of the present invention, the water scavenging and the air permeability are improved, which makes it possible to control the soil humidity suitable for growth.

Moreover, in planting trees, even when the container is buried in the ground, the water is well drained, so that the growth is carried out under the same conditions as when there is no container, and the roots are restricted from spreading laterally.

[Effects of the Invention] The pot cultivation container of the present invention has good water scavenging and air circulation in the pot cultivation isolated from land such as mandarin oranges, and can efficiently manage nutrients and water suitable for growth. In addition, since it is lightweight and can be folded and stored until use, it has advantages that it is easier to transport and work than conventional wooden containers, and the container is self-supporting, so tree planting work can be done by one person.

The lack of self-sustainability in the case of a non-woven fabric container of a normal form was a fatal drawback that markedly impaired workability as a pot cultivation container.

With the structure of the present invention, it is possible to achieve reliable self-standing by adding a simple sewing process, and it is possible to utilize the advantages of non-woven fabric with good air permeability and the advantage of weight reduction for the pot container. Is remarkable.

In addition, the same effect as above can be obtained in pot cultivation of plant trees, and when the plant of the present invention is used when planting plants in the land, the roots of the plants do not spread, they are self-supporting, lightweight and foldable. The advantage is that tree planting work is easy and labor costs can be significantly reduced.
