Description

[Detailed Description of the Invention] The present invention relates to a container component used for temporary cultivation of plants, from raising seedlings to planting, and is lightweight and easy to handle, and is extremely convenient and can significantly save labor in cultivating and planting plants.

Traditionally, plants that require transplanting, such as trees that are grown as seedlings and then planted (planted), have been grown in open fields, and at the time of planting, the roots are cut and dug up, and the roots are then packaged and transported. However, there were drawbacks such as a great deal of labor involved in digging up the trench and packing the seeds, and poor rooting.Therefore, recently, seedlings have been grown in containers and transported directly to the site. However, the containers used for this purpose are hard plastic, tin, clay pots, etc., and are quite heavy and difficult to handle, especially when removing containers during planting. is extremely troublesome.

In view of the above, the present invention aims to provide a container component that is easy to handle and can be constructed into a container for use in raising seedlings or other temporary cultivation of plants such as trees, and can be easily removed during planting. It is.

Next, embodiments of the present invention will be described based on the drawings.

The container component a according to the present invention is a thermoplastic resin foam mainly composed of polyolefin resin such as polypropylene, and the resin foam strip 1 has a high density on the surface and a low density on the inside.
It is made of a composite wood board made by arranging a large number of strips in parallel, converging them, and fusing adjacent strips to each other.

The resin foam strips 1 and 1 are fused together by simultaneously extruding thermoplastic resin in a large number of strips from a die at the tip of the extruder to foam it, and immediately after extrusion, passing it through a predetermined mold to restrict foaming and mutually This is done by bringing them into close contact.

Therefore, a high-density skin layer 2 is formed on the surface of the synthetic wood, and the fused portions 3 between the strips 1 are also high-density.

In addition, examples of the above-mentioned thermoplastic resin mainly composed of polyolefin resins include single resins such as polypropylene or polyethylene, mixed resins of these and polystyrene, and copolymers mainly composed of polyolefils. A polypropylene resin alone or a mixed resin of polypropylene and polystyrene containing 50% or more of polypropylene is suitable.

Therefore, in the present invention, a cut groove 4 perpendicular to the length direction of the resin foam strip 1 is formed on one side of the synthetic wood board as described above so as to leave at least the skin layer 2 on the other side. It is characterized in that it is provided at predetermined intervals in the length direction, and is bent at the kerf 4 so that it can be wound into a cylindrical shape.

The kerf 4 may be in any form, such as a relatively narrow concave groove as shown in the figure or a ``groove'', but if it is a ``groove'', it can be bent with the layer inside.

The depth of the cut groove 4 is determined according to the thickness of the plate material so that at least the skin layer 2 on the other side remains.

Further, the intervals between the kerfs 4 can be set arbitrarily, but if the intervals are small, it can be wound into a cylindrical shape close to that of a cylinder.

In addition, the synthetic wood board may be sized to a predetermined length depending on the size of the container to be constructed, or it may be left in an elongated shape in the length direction of the resin foam strip 1. It can be cut to an appropriate length when
It can be easily cut at these points.

The container component a of the present invention is configured as described above,
When using this, it is bent at an arbitrary angle at each of the grooves 4 provided at predetermined intervals in the longitudinal direction, and wound into a polygonal cylinder shape as shown in Fig. 4, and the ends are butted against each other. The cylindrical shape may be held by tightening the outer periphery of the tube with a string or a band 5 or the like.

When the cylindrical body is used as a side frame in combination with a bottom plate (not shown) to form a container such as a flowerpot used for temporary cultivation of plants, the bottom plate is formed into a polygonal shape corresponding to the cylindrical shape. , it is sufficient to attach this to the container component a of the present invention by means of a removable fitting or locking means, for example, by providing a groove on the inner periphery of the lower end of the container component a, and attaching the layer to the periphery of the bottom plate. The parts can be fitted simultaneously with the above-mentioned winding configuration.

A hole for water permeation is provided in the bottom plate.

Note that if the location of the cut groove 4 to be bent is selected appropriately, the fifth
It is also possible to configure it into a rectangular or other rectangular cylindrical shape as shown in the figure, and in this case, the bottom plate may also be formed into a corresponding rectangular shape.

Of course, it is also possible to construct a container for temporary cultivation of plants by combining the cylindrical body made of the container component a with another bottom member instead of the bottom plate described above.

In addition, the container component a of the present invention can be used alone as a cylindrical body made by winding it for temporary cultivation of plants with the bottom open, and in this case, the cylindrical body can be installed in an open field, etc. However, in order to make it easier to separate the open ground from the soil inside the tube when moving during planting, it is recommended to spread a water-permeable sheet or net such as paper or straw. .

Furthermore, when transporting during planting, even if there is no bottom, there is little risk that the soil inside will fall out due to roots spreading, and it can be transported as is.

As mentioned above, the container component a of the present invention is wound into a cylindrical shape and used as a container with this as a side frame, or the cylindrical body is used for raising seedlings of plants such as trees and for temporary cultivation until planting. At the time of planting, the container is transported as is, and at the same time, the container or the cylindrical body, that is, the container constituent material a wound into a cylindrical shape, is removed by releasing the binding with a band or the like. .

Therefore, the container component a of the present invention is made by arranging and converging a large number of resin foam strips with high density on the surface and low density on the inside in parallel, and fusing adjacent strips to each other. Since it is made of synthetic wood board material, a high-density skin layer 2 is formed as a characteristic of its manufacturing, and the thermoplastic resin of the material is mainly composed of polyolefin resin such as polypropylene. It has excellent toughness as a whole, and especially the high-density parts of the skin layer 2 and the fused parts 3 between the strips have high toughness and have some elongation.

In addition, the present invention creates grooves 4 perpendicular to the length direction of the resin foam strips on one side of the synthetic wood board as described above, leaving at least the skin layer 2 on the other side, so as to form a cut groove 4 in a predetermined length direction. Since they are provided at intervals, at least the thin remaining portion of the skin layer 2 formed by the cut grooves 4 can act like a rehinge due to the toughness and elongation of the skin layer 2, and can be easily bent as described above. This makes it possible to easily form a cylindrical winding structure that is bent at the cut groove 4 without any inconvenience.

Moreover, even though the remaining portion of the cut groove 4 is quite thin, it has excellent toughness due to the skin layer 2, and in particular, the cut groove 4 is perpendicular to the length direction of the resin foam strip 1, and the strips are close to each other. Coupled with the fact that the fused portion 3 is continuous in the remaining portion, it does not easily separate even if it is repeatedly bent, and can sufficiently withstand use as a container for temporary cultivation of plants.

Furthermore, since the present invention is made of a foamed synthetic wood board as described above, its thickness can be increased considerably without increasing the amount of resin compared to non-foamed materials, and therefore the structure is wound into a cylindrical shape. In this case, due to the thickness, both ends can be easily held in a butt-to-edge structure with just end faces, as in the illustrated embodiment.

Furthermore, due to the cushioning properties unique to synthetic wood, it is possible to reduce the impact caused by collisions with other objects during transportation to the planting site, and the roots of cultivated plants are well protected.

In addition, in the case of the present invention, as described above, the structure is bent at the cut groove 4 and wound into a cylindrical shape, and this is used by holding it tightly with a band, etc. It can be easily peeled off simply by releasing the bondage, etc., and the removal work can be easily performed.

In particular, the container component of the present invention is much lighter and easier to handle than clay pots, etc., and in addition, it can be bent at the grooves provided at predetermined intervals, so it can be easily disposed of before or after use. At this stage, it can be handled by folding it as shown in Figure 8 or by rolling it into a low-volume shape as shown in Figure 9, handling operations such as storage and transportation, and processing operations after removal during planting. can be made significantly easier.

Moreover, the present invention has a woody appearance, so it looks good.
Furthermore, it has excellent water resistance and is free from corrosion, allowing long-term use.

As described above, the present invention enables easy assembly and construction of containers used for raising seedlings of plants such as trees and for temporary cultivation until planting.
Furthermore, removal work at the time of planting can be easily performed, and handling is convenient, and the labor required for cultivating and planting plants can be significantly reduced.

Furthermore, the present invention can also be used as a protection material for the roots of plants grown outdoors when they are transported to a planting area by being wrapped around the roots.
