Description

[Detailed Description of the Invention] The present invention relates to a pot box as a seedling-raising device used for sowing seeds or growing seedlings from young seedlings to obtain seedlings for transplantation or actual planting.

Various proposals have been made for this type of seedling-raising device, but those in which the storage recess has a continuous tapered shape from the upper opening to the drainage hole at the bottom have good drainage, but the lower part is narrower and the storage recess has a continuous taper shape. Because the volume is small, it is not suitable for growing relatively large seedlings, and even if the volume is large, those with a flat bottom have poor drainage.

In particular, this type of seedling raising device (box) is often used by placing it directly on the open ground or on the floor. If the drainage hole is blocked by contact with the soil, it will not be possible to secure the drainage and ventilation necessary for root growth.

Therefore, for this type of seedling growing device, in addition to ensuring that the storage recess has sufficient volume for root growth and good drainage, it is also important to ensure drainage and ventilation, especially on the bottom side of the bottom when placed directly. is also an important element.

In addition, it is desired that handling such as transporting seedlings while growing them or transporting them when not in use can be done easily, efficiently, and safely.

In view of the above, the present invention was devised in an attempt to provide a potted box as a seedling-raising device suitable for raising seedlings, handling such as transportation, and other uses.

That is, in the pot box of the present invention that solves the above-mentioned problems, the storage recess for raising seedlings is formed in a steeply tapered shape downward from the opening, and in the lower part thereof, the concave part continues from the tapered surface part to the periphery of the drainage hole in the center of the bottom. Formed in a gently tapered shape with good drainage and a large volume, it can form a root ball suitable for transplanting and main planting, and can also be used suitably for growing relatively large seedlings. It also allows for easy work.

In particular, the present invention is based on the pot box described above, and by providing a flow means that communicates with the side from the drainage hole on the lower surface of the bottom of each storage recess, the pot box can be placed outdoors, on the floor, or on a shelf. Even when placed directly on top, sufficient drainage and ventilation can be ensured, allowing for good root growth.

In addition, the upper edge of the circumferential side is divided equally into four symmetrical sections in the front and rear and left and right directions, with one opposing two sections.
An inner projecting edge is provided in one section, and an outer projecting edge corresponding to the inner projecting edge is provided in the other two opposing sections so as to be symmetrical with respect to each other. The outer projecting edge and the inner projecting edge corresponding to the projecting edge and the outer projecting edge are respectively provided in vertically corresponding sections. As a result, pot boxes of the same shape can be used stably as covers or lids when raising seedlings or transporting seedlings.Moreover, when empty pot boxes are stacked one on top of the other, the upper and lower pot boxes cover the entire periphery. It is designed to fit on the sides.

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

A is a pot box for raising seedlings according to the present invention made of synthetic resin foam, and has a large number of storage recesses 16 for raising seedlings that are open on the top surface and arranged in parallel vertically and horizontally. I am doing it. The accommodation recess 10 has at least its inner surface tapered downward from the upper opening 2 with a relatively gentle slope with respect to the horizontal plane, and is bent inward from the lower end of the steeply sloped tapered surface portion 1a at its lower part. The bottom part 3 is formed in a more gently tapered shape continuing to the periphery of the drainage hole 4 at the center of the bottom part 3, and this gently inclined taper surface part 1b also serves as the bottom surface. It is desirable that the boundary between the tapered surface portions 1a and 1b be slightly rounded. In the case of the illustrated embodiment, the accommodation recesses 10 have a container shape in which adjacent ones are connected only at the upper part and are separated and independent at the lower part, and the outer surface of the accommodation recess 10 is
It is also possible to form a two-step tapered shape corresponding to the inner surface so as not to change the wall thickness of 0.
In the figure, the steeply inclined taper surface and the lower surface of the bottom portion 3 are connected by a rounded surface.

The planar shape of the accommodation recess 10 described above may be substantially rectangular in plan with relatively large rounded corners as in the embodiments shown in FIGS. 1 to 5; ), or the planar circular shape shown in Figure 8 (Figure 9).
It may be a planar hexagon as shown in the figure) or other polygons; in particular, a planar substantially quadrilateral with rounded corners;
In the case of a planar shape such as a circular planar shape or a planar hexagonal planar shape with large corner angles, it becomes easy to pull out the seedlings during transplantation and main planting, and the shape retention of the root ball is improved. Further, when the accommodation recesses 10 are hexagonal in plan, they can be arranged side by side without waste by arranging them in a honeycomb shape as shown in FIG. This accommodation recess 1
0 generally has an opening diameter and depth of 4 to 10 cm, a wall thickness of about 1 cm, and a drain hole 4 diameter of about 0.5 to 2.0 cm, but of course it can be implemented with dimensions other than the above.

Furthermore, on the lower surface of the bottom part 3 of the accommodation recess 10,
A flow means is provided which communicates laterally from the drain hole 4, and in the embodiments shown in FIGS. Several groove-shaped recesses 5 are provided.
That is, when the pot box A of the present invention is placed directly and used, the recess 5 improves drainage and ventilation from the drainage hole 4, and has the effect of assisting root growth. There is no problem in stacking them like this, and ventilation can be ensured in this state. Furthermore, as a means for water drainage and ventilation, a rib-shaped protrusion 5' may be provided on the lower surface of the bottom 3 in place of the groove-shaped recess 5 as shown in FIG. Also, the lower surface of the bottom part 3 other than the convex part 5' can be raised from the installation surface to provide a gap as a means of circulation, which has the effect of improving drainage from the drainage hole 4 and ventilation. The convex portions 5' may be formed radially around the drain hole 4, or may be formed in various other ways.

Further, the circumferential side part 6 of the whole pot box is formed to form a vertical plane, and the upper edge is divided into four parts symmetrical about the center line in the front and rear and left and right directions, and one Inner flange 7a in two opposing sections
The inner protrusion 7a is attached to the other two opposing sections.
The outer protruding edges 7b which are biased further outward are provided so as to be point symmetrical to each other. That is, in the case of the pot box A having a substantially rectangular plan view as in the illustrated embodiment, it is divided into four equal parts at the center of each side, and the inner flange 7a is in the section facing one diagonal, and the inner flange 7a is in the section facing the other diagonal. The outer projecting edges 7b are provided point-symmetrically to each other, so that an empty pot box of the same shape is placed over the pot box as shown in FIG. 5, and the corresponding inner projecting edges 7a and outer projecting edges 7b are fitted together. This allows it to be used as a cover or lid when raising seedlings or transporting them.

Further, on the lower edge of the circumferential side portion 6, an inner protruding edge 7a of the upper edge is provided.
and the outer protruding edge 8 corresponding to the outer protruding edge 7b, respectively.
b and the inner protrusion 8a are provided symmetrically in the vertically corresponding sections, respectively, so that when the empty pot boxes A are stacked vertically, they fit into each other vertically. In particular, if the circumferential side portion 6 is extended vertically toward the lower edge, the seedlings can be stacked in multiple stages when growing seedlings.

The synthetic resin foam that is the constituent material of pot box A includes styrene resins such as polystyrene and styrene-based copolymers, polyvinyl chloride resins, ABS resins, polyolefin resins, polyurethane resins, and other synthetic resins. Foams, especially relatively hard synthetic resin foams, are preferably used and are integrally formed mainly by bead foam molding.

The present invention is constructed as described above, and each storage recess 10 is filled with soil suitable for raising seedlings, and plants to be raised are sown, or germinated by solid sowing in a separate location. Plant young seedlings, transplant,
This is used to grow seedlings for actual planting.

Therefore, in the pot box of the present invention, the inner surface of the storage recess 10 is formed by continuously bending the steeply inclined tapered surface part 1a at the upper part and the gently inclined tapered surface part 1b at the lower part, and extends over the entire area up to the drainage hole 4 at the lowest part. is a sloped surface,
Unlike the case where the bottom has a horizontal flat part, there is no risk that water such as irrigation water or rainwater will accumulate at the bottom, and drainage performance is extremely good.

In particular, in the case of the present invention, a flow means is provided on the lower surface of the bottom of each storage recess 10, which communicates with the side from the drainage holes 4, so that it can be used even when placed directly on the open ground or on the floor. The periphery of the drain hole 4 does not touch the ground on the lower surface of the bottom, but communicates with the side through the circulation means. Therefore, even without providing a stand or support means on the side of the pot box to float the entire bottom, water such as irrigation water or rainwater flowing out from the drainage hole 4 is immediately drained to the side, and the drainage hole and storage recess 10 There is no risk of the water remaining in the inner bottom, and this, together with the drainage performance provided by the tapered surface within the housing recess, ensures extremely good drainage performance. Further, the air permeability necessary for root growth can be ensured by the above-mentioned distribution means.

In addition, the inner surface of the accommodation recess 10 has a steeply sloped upper part.
By forming the lower part into a gently tapered shape, it has a larger volume than a continuous tapered shape from the upper opening to the drainage hole at the bottom, making it suitable for transplanting and main planting without hindering root growth. It can form a root ball with volume, and is suitable when it is necessary to metamorphose relatively large seedlings. In addition, the steep and gradual taper of the inner surface makes it easy to remove seedlings during transplanting and actual planting, and since the lower part of the root ball is relatively thick, the shape retention of the root ball is improved. Transplanting can be done without damaging the roots. Furthermore, since it is a synthetic resin foam, it is lightweight, easy to handle, and has good heat insulation properties, and can reliably alleviate low-temperature damage during the cold season, high-temperature damage during the hot season, and radiant heat damage in the root threads of plant seedlings.

Not only that, but especially in the present invention, the upper edge of the circumferential side 6 of the pot box A is divided into four symmetrical parts in the front and rear and left and right directions, and one of the two opposing parts has an inner side. an outer projecting edge 7b that biases the projecting edge 7a outward from the inner projecting edge 7a into two opposing sections;
are arranged so that they are point symmetrical, so
When an empty pot box A of the same shape is turned upside down and placed on top of this pot box, the inner ridge 7a of the upper pot box A and the outer ridge 7b of the lower pot box A are connected to the upper pot box A. The outer projecting edge 7b of the pot box A and the inner projecting edge 7a of the lower pot box A fit into each other in vertical correspondence. In particular, even if the upper pot box is turned 180 degrees, it will fit in the same way.

Therefore, as illustrated in Fig. 5, an empty pot box A
is attached to the potted box A in which the seedlings are planted, like a lid, to serve as a heat-retaining cover for raising seedlings in cold weather, or as a cover or lid to protect the seedlings during transportation while raising seedlings. It can be used as a container, provides good protection for seedlings, and is economical as there is no need to prepare any other special lid or cover. Of course, since they can be attached stably in a fitted state, they can be stacked in a stacked state, and since they are made of synthetic resin foam and are lightweight, they can be easily transported and moved.

Moreover, on the lower edge of the circumferential side portion 6, an outer protruding edge 8b and an inner protruding edge 8a corresponding to the inner protruding edge 7a and outer protruding edge 7b of the upper edge, respectively, are provided in vertically corresponding sections. Therefore, when a plurality of empty pot boxes A are stacked one on top of the other, the inner and outer projecting edges 7a, 7b and 8b, 8a of the upper and lower pot boxes will fit into each other, so that the empty pot boxes It also becomes easier to transport and handle the pot box.

As described above, according to the present invention, as a seedling raising device used for growing seedlings for transplantation and actual planting, it has good drainage performance, especially when placed directly, and ventilation, and has a large volume. It is possible to grow well-grown seedlings suitable for transplantation, and it is also easy to remove the seedlings at the time of transplantation.

In addition, the pot box itself becomes a transport box, and when transporting and transporting seedlings, it can reliably reduce the blows and shocks especially to the root threads, which not only minimizes root pain during transport, but also an empty pot box,
When raising seedlings or transporting seedlings, the empty pot box can be used as a cover or lid in a fitted state, making handling such as transportation easier, and the empty pot box can be kept in the fitted state. They can be stacked on top of each other, making them easy to transport, store, and handle when not in use.

Therefore, it can be used suitably for agricultural or horticultural purposes, and can be used for raising seedlings of garden plants until they are transplanted into decorative pots and shipped for final sale, or directly to the site for planting in the gardens of housing complexes, etc. It can also be suitably used as a pot box that can be transported.
