Description

[0001]
[Technical field to which the invention belongs]
TECHNICAL FIELD The present invention relates to a seedling transplanting pot that is formed into a quadrangular or hexagonal cylindrical shape by spreading, and more particularly, to a pot with a bottom provided with a bottom piece for preventing soil escape at the bottom.
[0002]
[Prior art]
Conventionally, it has been widely practiced to grow seedlings in a square or hexagonal cylindrical pot formed by spreading a paper or a thin film such as paper, and transplant the grown seedling together with the pot body. When the caliber of the plant is large, soil breakthrough occurs during handling at the time of transplantation, and the growth after transplantation is delayed.
[0003]
Therefore, conventionally, for example, in Japanese Patent Publication No. 5-6, Japanese Patent Application Laid-Open No. 7-31292, Japanese Patent Application Laid-Open No. 7-31293, etc., a bowl body that forms a square or hexagonal cylinder shape by expanding or facing each other is disclosed. It has been proposed that an extension is provided in advance under an adjacent side wall, the tip or side edges of the extension are pasted together with a water-resistant adhesive, and the extension is used as a bottom piece according to development. Yes.
[0004]
[Problems to be solved by the invention]
However, according to the bowl with a bottom described in the above publications, since an extension part as a bottom piece is required in addition to the part forming the bowl, not only the material used but also a lot of material loss occurs. However, there is a problem that the cost burden increases. Moreover, although this kind of bowl is normally handled as a flat state, there existed a problem that the area in a flat state expanded by existence of the said extension part, and the cost concerning storage and conveyance also increased.
[0005]
The present invention has been made in view of the above-described conventional problems, and the object of the present invention is to form a bottom piece in the material necessary for forming the pot body, thereby reducing the material used and improving the handleability. It is to provide a bowl with a bottom that contributes to the above.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a seedling transplanting pot that is formed into a quadrangular or hexagonal cylindrical shape by developing at least two side walls that face each other or are adjacent to each other in the height direction. The tip portions of the sections are pasted with a water-resistant adhesive to form a bottom piece.
Thus, by using the section cut and raised from the side wall as the bottom piece, there is no material waste, and the bottom piece is housed inside, so that the area when flattened is reduced.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0008]
1 to 3 show a first embodiment of the present invention. In these drawings, reference numeral 1 denotes a pot with a bottom according to the present invention, which is composed of a hexagonal cylindrical pot main body 2 and a plurality of bottom pieces 3 provided on the inner bottom of the pot main body 2. The bottom piece 3 is formed by sticking the tip portions of the sections 4 and 5 formed by cutting and raising opposite side walls of the bowl body 2 with a water-resistant adhesive 6. Here, two pieces 4 and 5 are provided for each side wall, and therefore the bottom of the bowl body 2 has a transmission structure in which two bottom pieces 3 are bridged.
[0009]
In the first embodiment, the bottomed pots 1 are connected to each other by a connecting piece 7 to form a continuous pot 8, and the continuous pots 8 are densely assembled with the bottomed pots 1. In addition to being superposed on each other, the space between them is stuck with a water-soluble adhesive to form a collecting bowl 9. The collecting pot 9 is normally stored in a flat state, and is expanded in a honeycomb shape by pulling in the left-right direction at the time of use, and in this expanded state, a medium is placed in each bottomed pot body 1 and seeded to concentrate. Can grow a large number of seedlings. On the other hand, since the water-soluble adhesive is dissolved by irrigation at the time of raising seedlings, if one end of the continuous pot 8 is pulled after raising seedlings, the stacked continuous pots 8 are separated from each other and drawn out in a row. Then, it becomes possible to continuously transplant the bottomed pot 1 together with the seedling by using a suitable transplanter.
[0010]
Since the bottomed pot body 1 used for raising seedling transplantation as described above has the bottom piece 3 on the inner bottom portion thereof, it is transferred when transferring the collecting pot 9 to the transplanter or from the transplanter to the planting surface. In doing so, no soil escape occurs from the bottom of the bottomed pot 1, and the transplanted seedlings coupled with the roots extending through the openings around the bottom piece 3 and the openings as cuts of the sections 4, 5. Grows smoothly. In addition, since the root is turning in the bottomed pot 1, the soil escape from the opening as the cut-up mark of the sections 4 and 5 is almost negligible.
[0011]
Here, the continuous bowl 8 is formed by laminating two paper sheets 10 and 11 having anticorrosion, and the two paper sheets 10 and 11 are adhered with a water-resistant adhesive 6. The bonded portion is provided as the connecting piece 7, and the non-bonded portion between the connecting pieces 7 is provided as the bottomed bowl 1.
[0012]
In order to manufacture the above-described collecting bowl 9, as shown in FIG. 4, a pair of U-shaped cuts at a predetermined pitch is made on two paper sheets 10 and 11 drawn in two stages synchronously from a roll (not shown). 12 is inserted, and the sections 4 and 5 to be the bottom piece 3 are formed. Subsequently, a water-resistant adhesive 6 is applied at a predetermined pitch to the mating surface of any one of the paper sheets 10 or 11 to obtain a coating surface 13 having a predetermined width. A water-resistant adhesive 6 is also applied to the tip portion to obtain a coating surface 14 having a predetermined width. The coating surface 13 is a portion corresponding to the connecting piece 7, and the non-coating surface 15 between the coating surfaces 13 is a portion corresponding to the bottomed bowl 1, and one of the coating surfaces 13 and the non-coating surface One of 15 is set as one unit, and this unit is set continuously in the drawing direction A of the paper sheets 10 and 11. At this time, the folded portion 16 is set for each predetermined number of units, and the water-resistant adhesive 6 is applied along the folded line 16a to obtain the narrow coating surface 17.
[0013]
Thereafter, the two paper sheets 10 and 11 are overlapped. By this superposition, the two paper sheets 10 and 11 are joined at the respective coating film surfaces 13, 14 and 17, and the continuous bowl 8 (FIG. 3) in which the bottomed bowl 1 is connected by the connecting piece 7 is completed. . Next, a water-soluble adhesive is applied to the surface of the continuous bowl 8 except for the region 15 '(FIG. 4) where the notches 12 are provided. Subsequently, the continuous bowl 8 is shown in FIG. Then, the laminate 18 is obtained by alternately folding back and right from the folded line 16a. This laminated body 18 represents the flat state of the collective bowl 9, and if it extends in the left-right direction, it will expand into a honeycomb shape as described above.
[0014]
Note that the number of the bottom pieces 3 in the first embodiment is arbitrary, and can be three or more. Further, the sections 4 and 5 for forming the bottom piece 3 may be provided not only on the opposite side walls of the bowl body 2 but also on adjacent side walls.
[0015]
FIG. 6 shows a second embodiment of the present invention. The bottomed pot body 21 according to the second embodiment is composed of a square cylindrical pot main body 22 and a plurality of bottom pieces 23 provided on the inner bottom of the pot main body 22. The bottom piece 23 is formed by sticking the tip portions of the sections 24 and 25 formed by cutting and raising adjacent side walls of the bowl body 22 with a water-resistant adhesive 26. Here, two pieces 24 and 25 are provided for each side wall, and therefore the bottom of the bowl body 2 has a transmission structure in which two bottom pieces 23 are bridged.
[0016]
In order to manufacture the bottomed pot 21, as shown in FIG. 7, a sheet of paper 28 having a binding margin 27 is prepared in advance, and the sections 24 and 25 are formed on the sheet 28. The water-resistant adhesive 26 is applied to the ends of the binding margin 27 and the opposite sections 24 and 25, and then a paper sheet 28 is wound around the binding margin 27. The bag is closed and the flat body 30 is completed so that the opposing sections 24 and 25 overlap.
[0017]
On the other hand, in order to gather the above-mentioned bottomed bowl bodies 21 into a gathering bowl, first, as shown in FIG. 8, the flat bodies 30 are shifted by ½ pitch and overlapped with a water-soluble adhesive. Separately from this, a continuous bowl 31 ′ is prepared in which the overlapping direction of the flat bodies 30 is reversed. Next, as shown in FIG. 9, continuous bodies 31 and 31 ′ in which the stacking direction of the flat body 30 is changed are alternately laminated through a water-soluble adhesive to form a laminated body 32. The laminated body 32 represents a flat state of the collecting bowl, and when this is pulled in the left-right direction, the collecting bowl (not shown) in which the square cylindrical bottomed bowl bodies 21 (FIG. 6) are densely assembled is developed. As a result, the seedling can be seeded in the bottomed pot body 21 and nurtured intensively. And after raising seedlings, each bottomed pot body 21 is easily separated by dissolving the water-soluble adhesive, so that each bottomed pot body 21 can be transplanted. At this time, the bottom piece 23 of the bottomed pot body 21 is provided. Therefore, the transplanted seedling grows smoothly as in the first embodiment. Here, the number of the bottom pieces 23 in the second embodiment is arbitrary, and can be three or more.
[0018]
In addition, the manufacturing method in the said 2nd Embodiment can be utilized as it is, and it can be set as the assembly pot which assembled the hexagonal cylindrical bottomed bowl. However, in this case, it is necessary to overlap the flat bodies while shifting by 1/3 pitch.
[0019]
【The invention's effect】
As described above in detail, according to the pot with a bottom according to the present invention, since the section cut and raised from the side wall is used as the bottom piece, there is no material waste, and the bottom piece fits inside, so that the flat state The area is reduced, and the manufacturing and storage costs as well as the storage and transportation costs are significantly reduced.
