Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling pot of a plant, and more particularly to a structure of a plant pot which has a high regression property and is easy to handle.

[0002]

2. Description of the Related Art Attempts have been made to systematically cultivate plants suitable for land in a natural climate. For example, Japanese Unexamined Patent Publication No. 6-56020 discloses that concrete blocks dusted with plant seeds or concrete blocks planted with plant seedlings are arranged on slopes of rivers.
Japanese Unexamined Patent Application Publication No. 9-3937 discloses a seedling pot formed from a concrete block. This plant pot has a sand layer on its surface, so it has moisture retention even in a severe environment, and moss growth can be observed. It is described that it has an advantage.

[0003]

The conventional plant growing pot is presumed to be applied to a concrete revetment surface of a river or a steeply sloped soil retaining surface covered with concrete. Technology. Further, concrete blocks have a fundamental problem that it takes a long time to reduce weathering to soil, they are difficult to handle due to their weight, and they are difficult to break due to vibration during transportation.

[0004] Conventional plant pots also have a problem in terms of aesthetics. Especially when planning greening in places where surface soil is present, such as mountains, seashores, city parks, flower beds in general households, etc., exposed blocks of concrete are not visually pleasing, and concrete fragments may be lost due to collapse during plant growth. Due to scattering, it is not practical in green areas and parks in urban areas.

[0005] Although there are many lands where systematic and artificial revegetation is desired, the problem is that if seedlings are planted as they are on the ground, the plants die without sufficient growth. The cause is, after all, the harshness of the natural environment and the difficulty of careful treatment. Plants and seedlings planted directly on the ground can grow to withstand the remaining grass roots, competing plants, temperature, humidity, rain, snow, wind, etc., but provide some protection until sufficient growth is achieved. Without it, the intended purpose cannot be achieved.

Various plant pots have been proposed to provide such a certain protection environment, but the protection conditions necessary for plant growth and the structure of the pot for achieving the same are reasonably high. Balancing is not always easy. Unlike mechanical and electrical devices, the plant pot is a natural counterpart, and it is necessary to balance the protection continuity of at least one year or more with the soil reducibility, beauty, and ease of handling of the pot itself. Because.

For example, in order to ensure moisture retention, cloth or newspaper may be placed in a container. However, this may instead cause root rot due to excess moisture. Use of a container impairs soil reducibility. As described above, when a certain condition is satisfied, the other conditions are not satisfied.

Accordingly, an object of the present invention is to ensure soil reducibility, sustained maintenance of shape / structure strength for a certain period of time, moisture retention, heat retention, and isolation from competitor plants, which are basic conditions of a plant pot, It is to balance a plurality of elements for practical use, that is, lightness (ease of transportation), ease of handling (ease of installation work), and maintenance of aesthetics, which are user's convenience.

[0009]

In order to achieve the above-mentioned object, a seed and breeding pot according to the present invention uses a paper panel having soil reducibility, and the paper panel has a substantially rectangular shape as a whole and extends along a longitudinal direction. The two-fold parallel folding curve arranged in advance in the upper and lower middle portions thereof is provided, and the parallel folding curve can be bent to form a double-structured wall having a certain clearance, and the paper can be formed. The panel includes a plurality of vertical folding curves at a predetermined interval, which are perpendicular to the parallel folding curves,
By bending the fold curve, the wall portion of the double structure can be formed into a substantially polygonal plane, and a portion having a substantially U-shaped cross section when the parallel fold curve in the longitudinal direction is bent is defined as an upper surface edge portion, and an inner wall is formed. A top cover made of a paper panel for closing the upper part is provided, and a bottom cover substantially matching the dimensions of the outer wall is provided with the opening of the double-structured wall having a certain clearance as the lower surface.

[0010]

The seed and breeding pot according to the present invention has the following conditions. Use thick paper panels with soil reducibility. The paper panel has a substantially rectangular shape as a whole. The paper panel is provided with two parallel folding curves that are arranged in advance in the middle of the paper panel along the longitudinal direction. By bending the parallel folding curve, a double-structured wall having a certain clearance is formed. The paper panel includes a plurality of vertical folding curves at a predetermined interval, which are perpendicular to the parallel folding curves. By bending the folding line, the wall of the double structure can be formed in a substantially polygonal plane. An upper lid made of a paper panel for closing an upper portion of an inner wall is provided with a portion having a substantially U-shaped cross section formed when the parallel folding curve in the longitudinal direction is bent as an upper surface edge. It has a bottom lid with the opening of the double-structured wall having a certain clearance as the lower surface, and the bottom lid almost matching the dimensions of the outer wall.

First, the first condition () is to secure the soil reduction property, light weight, and easy handling of the pot itself. Since it is basically made of paper, it returns to the soil naturally after achieving its purpose. Also, since it is assembled at a site where greening is required, there is no transportation cost, there is no damage during transportation, and it is easy to carry around the site, and it can be easily handled by children and women and women without physical strength.
When cardboard is used as the paper panel, there is an advantage that the moisture retention and the heat retention are improved, and the production cost can be reduced, and this is the most excellent material.

The second condition () is that the upper and lower surfaces of the pot are made parallel so that the upper and lower lids () made of paper can be attached. The seedling pot according to the present invention has a structure to obtain the final result by folding,
Even in terms of ease of handling, it was formed into a substantially rectangular shape, making the on-site folding work more efficient.

The third condition () is that the side wall of the pot has a double structure, the rigidity of the paper pot itself is secured, and a predetermined structure holding material is formed in the clearance gap formed by the double side wall. (Soil-reducing substances), for example, soil, sand, gravel, newsprint containing moisture, cement mixture, and the like. The structure retaining material to be filled is appropriately selected depending on the environment in which the pot is used. Use of cement should be avoided as much as possible in general use environments, but in places where a certain level of structural strength is required, such as rivers and beaches, where there is a lot of moisture, and where there is high earth pressure such as slopes, Continuously guarantee the structural strength of the buried pot. When the side wall clearance is set to, for example, 40 to 50 mm, the concrete filled therein easily collapses in several years, and the particles are reduced to soil.
In an area showing special vegetation, it is desirable to fill the surrounding soil peculiar to the area, match the structure of soil particles and the active microorganisms inside and outside the pot, and expect straightforward growth.
Also, when the newspaper is wetted and squeezed and loaded inside the double wall, the newspaper is solidified as it dries, and a strong structural strength can be obtained. A piece of paper cut by a shredder also becomes a similar strength reinforcing material when wet and squeezed. Of course, these spoil over time and are reduced to soil.

The fourth condition () defines the shape of the pot. The plane shape of the pot may in principle be circular or triangular. However, considering the ease of handling, when bending a number of upper and lower parallel lines (folded curves) to complete the pot, if the number of bends is too large, the handling becomes complicated. Since the internal volume of the main body is too small, the main body is formed into a square formed by folding at least three times, an octagon formed by bending at most seven times, and preferably a regular hexagon formed by bending five times. This is because the regular hexagon makes it easy to form a pattern between adjacent pots, and allows a free greening design. Further, application to a curved surface including a spherical surface is also free. Furthermore, since it is possible to maintain wall rigidity (area) sufficient to support the earth pressure applied to each side wall at each side wall, it is particularly advantageous when the apparatus is arranged on a slope.

The fifth condition () is important for ensuring moisture retention (preventing drying) and preventing invasion of herbs. In the pot according to the present invention, an upper surface edge is formed when a parallel folding curve extending in the longitudinal direction is bent. This is set as the upper side of the pot, and a filler (particularly soil) to be charged into the pot is shielded by disposing an upper lid made of a paper panel that closes the upper part of the inner wall so as to close the cavity of the main body of the pot. The vegetation pot according to the present invention is used by burying it in the soil, but is not completely buried in the soil, so that the upper surface is exposed above the ground, receives rainwater, and the invasion of herbaceous plants in the surroundings. To prevent

By providing the upper lid, an effect of preventing the propagation of weeds is obtained. When the nearby soil is used, the seeds of the weeds mixed in the soil may grow, but if the top cover is arranged, the sunlight is blocked, so that the weeds cannot grow. Since the void body is filled with soil, the upper lid can be easily mounted simply by placing it on the soil. It is desirable to arrange the upper lid at a position slightly lower (for example, about 1 cm lower) from the upper surface of the pot so as to easily receive rainwater.

It is also important that the pot according to the present invention retains aesthetics. If the beauty is neglected, it is possible to reverse the top and bottom and use the double wall with the clearance opening facing upward to expose above the ground surface. However, such a method of use leaves a problem of breaking the landscape when a different color soil grain (for example, cement) is used in the clearance gap or the pot body gap, for example. This can be a problem, for example, when used in parks and home flower beds.
Therefore, in the pot according to the present invention, a pot having a regular planar shape is arranged without showing the soil loaded therein to the outside, and the paper material on the surface and the internal soil are returned to the soil within a certain period of time. By doing so, the prejudice to the shade of the filled soil, especially the shade of cement, is eliminated. As described above, even if cement is filled in the inside of the double wall (clearance gap), collapse and reduction in a short period of time can be guaranteed, but there are some things that seem unnatural (dislike / misunderstanding). Therefore, by completely blocking and closing the upper exposed surface with the paper panel, it is possible to promote greening of parks, planned greening of mountainous areas, or flower bed cultivation of ordinary households without resistance. .

The sixth condition () is intended to promote understanding of the seed and breeding pot according to the present invention when it is widely used by ordinary citizens regardless of age group. That is, since the vegetation pot according to the present invention is basically used by burying it in the soil, the bottom cover is not necessary in principle. However, because of the certain regulatory concept of vegetation pots,
Without the bottom lid, it was not clear which side to use with the top facing up, and confusion could occur during actual use. Therefore, a bottom cover is also provided to close the clearance opening on the lower surface, and the shape is similar to that of a normal pot (potted plant) to prevent confusion during use.

The ease of understanding when assembling and using the pot is a structural feature that is indispensable for promoting greening widely. In addition, by providing the bottom cover, seeds and seedlings in the pot can be reliably protected from competing plants in the area, so that at least the growth rate is surely improved. It is desirable to provide a drain hole in the bottom lid. Since it is a paper pot, a gap is naturally formed at the junction between the bottom lid and the outer wall, and excess water is discharged into the lower soil from the gap. However, the difference between the members of the top cover and the bottom cover can be intuitively understood, so that even a beginner does not decrease the assembly efficiency. Vegetation pot according to the present invention children, women, women, the elderly,
Avoid widespread misunderstandings, incorrect usage, and reduced workability due to hesitation, assuming wide use by foreigners.
Structural considerations have been taken so that anyone can easily and freely contribute to the greening business. Since the bottom lid is in the soil, it rots in about two weeks.

[0020]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A seedling raising pot according to the present invention is obtained by folding a substantially rectangular paper panel (for example, corrugated cardboard) 10 as shown in FIG. 3 to form a polygonal double-walled pot as shown in FIGS. The main body 30 is formed, and the pot main body 30 is
And a bottom lid 60, and as shown in FIG.
Fill in the middle part to use. In addition, 11 is two parallel folding curves along the longitudinal direction, 12 and 14 are a suitable number of folding curves forming a right angle, 31 is an outer wall surface, and 35 is an inner wall surface. 40 is a double wall clearance gap, 45 is a pot main body gap, and 47 is an upper surface edge.

First, the paper panel 10 has a substantially triangular punching portion 48 so that the upper surface 47 of the adjacent side wall panel (31, 35) does not overlap when the folding curves 12 and 14 in the vertical direction are folded back. Is desirably provided. In addition, in order to facilitate bending of the inner wall surface 35 of the pot body 30, a score line 49 forming the inner wall surface 35 is provided with a cut line 49 in parallel with the bent curve 14. This is because the cut lines 49 allow the angle of the inside bend to be automatically adjusted with a small force. 16 is a paper panel 10
And 17 are slits for inserting and locking the locking pieces 16.

The bending curves 12 and 14 in the vertical direction have different bending radii between the inner wall surface 35 and the outer wall surface 31. Therefore, the bending curve 14 of the outer wall surface 31 is formed from the apex of a substantially triangular punched portion 48. The folding curve of the wall surface 35 and the cutting line 49 are formed from the top of the bottom of the punched portion 48, respectively, so that a predetermined positional shift is provided on the left and right sides to absorb the difference in the bending radius.

At the time of use, the paper panel 10 is bent, the locking pieces 16 are inserted into the slits 17 and adhered,
The pot body 30 is made. At the time of folding, an adhesive tape or a staple (for example, a staple) may be used for temporary fixing. Then, with the clearance gap 40 between the inner wall surface 35 and the outer wall surface 31 facing upward, an appropriate shape holding material such as soil, sand, gravel, wet newsprint, or a cement is loaded, and then a bottom lid for closing the clearance gap 40 Cover with 60. In this case, the locking pieces 65 arranged on the outer periphery of the bottom lid 60
Is bent and adhered to the inner surface of the outer wall surface 31 using an adhesive tape or the like to prevent the bottom cover 60 from falling off. However, when the bottom cover 60 is to be put on the site, it is only necessary to place the pot on the ground while holding down and holding the hand, so that the adhesive fixation is not particularly important for the accustomed person. 63 is a hole for water drainage and overhanging of the root.

After the bottom body 60 is attached and the pot body 30 is placed on the ground, soil is put into the body space 45 of the pot together with seeds and seedlings. Root nourishes, plant actives, rhizome accelerators and fertilizers may be used. Thereafter, the top cover 50 is covered. When planting a seedling, the seedling is inserted into the slit opening 59 of the top cover 50, the root is put into the soil, and the top cover 50 is attached.
It is needless to say that the upper lid 50 may be provided with an appropriate number of openings for absorbing water in an appropriate shape.

According to such a seedling pot, transport to the site where greening is to be performed and handling at the site are extremely easy.
After the charging material for maintaining the shape is inserted into the clearance space 40, the shape of the pot body 30 can be reliably maintained for a certain period. Since only the paper panel 10 is folded, the general public can participate in greening regardless of age and gender.

After the installation, the paper panel 10 and the shape holding material loaded in the clearance space 40 are in harmony with each other, so that appropriate moisture absorption, moisture retention, and heat insulation are maintained. In addition, since seeds and seedlings are blocked from the roots of competing plants and surrounding plants in conjunction with the bottom lid 60, seedlings can continue to grow in a safe state for a certain period of time. The type of the shape holding material to be loaded into the clearance gap 40 is set so that the pot body 30 collapses for a predetermined period, preferably one to two years. Since the portion 47 remains, the appearance of the pot is maintained as it is at the initial stage, and there is no fear that the beauty of the surroundings will be spoiled. Then, as the plants grow, the pot body 30 also collapses and returns to natural soil.

When used on dry land where the amount of rainfall is small, a suitable moisturizing material such as newsprint paper (shredder paper piece) wetted with water and squeezed together with the soil or alone is put in the clearance space 40 of the pot. It is desirable to supply water for a long time. Newsprint not only recycles resources, but also has the property that when squeezed and densely packed, it solidifies with drying and exhibits strong structural strength. Handling is easy. In addition, as a result of disposing the bottom lid 60, the ability to guarantee moisture is remarkably improved in terms of moisture retention.

The plane shape of the pot can be freely designed, such as a triangle, a quadrangle, a pentagon, a hexagon, an octagon, a dodecagon, etc., but the number of vertical folding lines (12, 14) is one less than that. For example, two, three, four, five, seven,
It appears as eleven. The same applies to the score line 49.

[0029]

As described above, according to the seedling-growing pot of the present invention, the basic conditions are soil reducibility, continuous retention of shape / structure strength for a certain period, moisture retention, heat retention, and the ability to maintain While ensuring the isolation and isolation, it is possible to balance the factors of lightness (ease of transport), ease of handling (easiness of installation work), and maintenance of aesthetics, which are the conveniences of the user. Greening plans can be promoted.
