DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved synthetic resin sheet for covering ridges and other soils.

[0002]

2. Description of the Related Art Covering ridges and other soils raises the soil temperature, thereby promoting the initial growth of crops, preventing the evaporation of soil moisture, preventing the flow of fertilizer, Alternatively, a synthetic resin film called a multi-sheet is used for the purpose of preventing solidification of the soil and the like.

[0003]

In this film, a large number of planting holes are arranged at appropriate intervals, and it is possible to sow seeds in soil or plant seedlings through each planting hole. There is a problem that the soil temperature cannot be increased because many perforations are open and the soil cannot be sealed, thereby delaying the initial growth of crops. In addition, there is also a disadvantage that the soil moisture near the planting hole evaporates and the soil hardens during covering and before sowing, so that the seed does not adjust to the soil during sowing.

[0004] In order to solve such a drawback, the planting hole may be opened and closed as required. A very common technique to make it possible is to polymerize the film as if closing the planting hole, but if the film is joined by welding or the like, it can be easily peeled off. Therefore, it is not suitable as a sheet used for the above purpose. Although this film must be able to be easily peeled off from the film in which the planting holes are arranged at appropriate intervals, on the other hand, the film has such adhesiveness that it does not peel off naturally. Must have. Most importantly, a multi-sheet having the above performance can be manufactured as easily as possible. This is because the more complicated the manufacturing process, the more the cost will be rebounded, and further consideration must be given to cost reduction in consideration of discarding after use. An object of the present invention is to provide a multi-sheet capable of meeting such a demand.

SUMMARY OF THE INVENTION The multi-sheet of the present invention
Is a film 1 in which planting holes 1b are arranged at appropriate intervals, and a film 2 for closing the planting holes 1b is removably superimposed on the film 1. In particular, the two films
Both of the joint surfaces facing each other are mirror-finished
Both joint surfaces are extremely smooth like
It has adhesive performance, and both
The two films 1 and 2 are joined together. When this multi-sheet is covered with ridges or other soil, the soil can be sealed by the film 1 in which the planting holes 1b are covered with the film 2. In this case, the two sheets
The joint faces of the lumps 1 and 2 facing each other
Both surfaces are extremely smooth like a mirror surface
Have adhesive performance, and both
Since both films 1 and 2 are joined together,
Film 2 for closing the 1b is not <br/> Re Rukoto peeled from the film 1 naturally.

[0006] Conversely, the film 2 can be peeled off the film 1 very easily, for example by hand. That is, fill the film 2 as necessary.
To expose the planting hole 1b.
come. Therefore, the workability is extremely excellent.

Also, a very smooth joint surface such as a mirror surface
Just join them as if facing each other,
Can film 2 be detachably polymerized to 1
Multi-seats with the above performance
Can be made.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, planting holes are provided at appropriate intervals on a synthetic resin band-shaped film 1.
1b, 1b are arranged in rows. It is convenient to manufacture the film 1 so as to be continuous in a strip shape, and it is preferable to cut the film 1 into an appropriate length according to the length of a ridge or other soil. Further, in the illustrated example, the case where the planting holes 1b are arranged in one row is shown, but the number of rows can be increased, such as two rows, three rows, or four rows, according to the seeding crop or the planting crop. Furthermore, the size of the planting hole 1b, the planting hole 1b, 1b
Can be appropriately changed according to the sowing crop or the planting crop or the use.

A synthetic resin film 2 for closing the planting hole 1b is removably polymerized on the film 1. The film 2 only needs to have at least a width and a length capable of closing the planting hole 1b.
1b Since it is extremely inefficient to polymerize the film 2 one by one in production, the film 2 is formed into a strip as shown in FIG.
It is good to block 1b, 1b. When a plurality of rows of planting holes 1b, 1b are formed at appropriate intervals in the band-like film 1, all the rows of planting holes 1b, 1b are completely covered with the band-like film 2. The width of the film 2 should be widened. As described above, when the film 2 for closing the planting holes 1b, 1b formed in the film 1 is formed into a band shape, the planting holes 1b, 1b are sequentially opened in the film 1 while the film 1 is being fed. Since it is possible to polymerize the film 1 while closing the planting holes 1b, 1b while feeding out the belt-like film 2, it is possible to efficiently manufacture a belt-like continuous multi-sheet.

The joining surfaces of the strip-shaped film 1 and the strip-shaped film 2 facing each other (in FIG.
a) are very flat like a mirror.
Both the joining surfaces 1a and 2a are assumed to have an adhesive property as a smooth material, and both films 1
2 is most ideally joined. In this case, the film 1 and the film 2 can be removably polymerized very easily. And planting hole 1
The film 2 that closes b is not spontaneously peeled off the film 1, and conversely, the film 2 can be peeled off the film 1 very easily, for example, by hand. Accordingly, the workability is extremely excellent.

[0011] Thus, the strip of film 1 and the strip of the joining surface 1a which face each other of the film 2, both <br/> to 2a by a very smooth surface like a mirror, like a mirror The film 2 can be removably polymerized on the film 1 only by joining the extremely smooth joining surfaces 1a and 2a so as to face each other. However, while applying pressure to the film 1 or (and) the film 2,
That is, when the two are joined while pressing, the joined state of both becomes extremely ideal, and the most ideal multi-sheet can be manufactured.

As shown in FIG. 1, the multi-sheet is preferably wound into a roll. When the multi-sheet is wound into a roll, it is very convenient because the multi-sheet can be automatically covered with ridges and other soils using a machine. It is also advantageous in terms of aspects. When winding the multi-sheet into a roll, the core 3 is preferably used.
In addition, while the bonding surface 1a of the film 1 is made to be smooth like a mirror surface, the opposite surface (the lower surface in FIG. 2) 1c is assumed to have minute unevenness. Also, even when the multi-sheet is wound up in a roll, the joining surfaces do not stick to each other.

This multi-sheet can be used for sowing various crops such as radish, ginseng, lettuce, corn, watermelon, melon, burdock, or planting seedlings. The colors of the films 1 and 2 can be various colors such as black, green, and silver in addition to the color of the films 1 and 2, depending on the purpose of laying and the application. Further, it is also possible to carry out by combining the colors of the films 1 and 2 in various ways.

[0014]

According to the multi-sheet of the present invention, the film 2 for closing the planting holes 1b is very simply compared to the film 1 having the planting holes 1b arranged at appropriate intervals.
If you can easily peel it off by hand ,
It is extremely excellent in terms of workability.
Since arm 2 has closed the adhesive to the extent that no Shimawa peel off naturally to the film 1, the film 2 is self during use
The film 1 and the film 1
The film can be easily bonded to the film 2.
Is very advantageous in terms of the manufacturing process,
Cost can be reduced.
