Description

  The present invention relates to a seedling pot in which a plant is planted in a period from production to sales.

  The seedling pot is made of soft resin such as polyethylene and polyvinyl chloride and is light (thin) and low-priced, and the impact on plant sales prices (including transportation costs) can be minimized. It is handled as a product. In this kind of seedling pot, it has been proposed to provide good drainage by providing a slit from the bottom to the side wall separately from the water hole provided at the bottom center. In addition, it has also been proposed that the inner container made transparent to check the tension of the roots of the plant and the outer container made opaque to improve the appearance are overlapped to make the inner and outer double specifications. (Refer to patent document 1 etc.).

  In this inner / outer double-species seedling pot, each side wall of the inner container and outer container is provided with a vertically long concave / convex fitting part that bulges inward and the outer part is recessed, and the concave / convex fitting part is fitted when overlapping. By combining, the slits of the inner container and the outer container are aligned so that they match each other. By performing this alignment, it is said that the action of ensuring the draining action can be obtained even at the time of superposition.

Japanese Patent No. 4116023

  Since the well-known seedling pots with internal and external double specifications can be drained well, when water is irrigated to the culture soil or plants in the inner container, excess water that has passed through the culture soil immediately passes through the lower slit to the outside of the outer container. Will be drained. As a result, it is said that the plant is less likely to cause root rot. However, the drainage by the slit is very high, and at the same time, it has the disadvantage that the culture soil is depleted and dried relatively quickly. Therefore, in order to prevent the plant from withering, it was necessary to repeat irrigation frequently.

This kind of seedling pot is often produced and sold outdoors or in a greenhouse. Therefore, even if drainage occurs from the water hole or slit in the bottom center due to irrigation,
There is no particular problem. However, when the purchaser takes it home, puts it in the room after returning home, or displays or sells it in the store, there is a problem in that the drainage pollutes the surroundings.

  The present invention has been made in view of the above circumstances, and prevents the plant from withering by preventing depletion and drying of the culture soil without frequent irrigation, and also by drainage accompanying irrigation. An object of the present invention is to provide a seedling pot capable of preventing defects in surrounding dirt.

In order to achieve the above object, the present invention has taken the following measures.
That is, the seedling pot according to the present invention has a bottom and a surrounding wall that forms a container that rises around the entire outer periphery of the bottom and opens at the top, and the surrounding wall has an upper portion in the height direction from the bottom. in seedling pots slit for communicating the container and out over to is provided, on the surrounding wall, with respect to the position of the mismatch and the slit in the circumferential direction around the vessel, and beyond the slit upper from the bottom A dent distance generated between a lower dent recessed inward of the container over a height range that does not reach the upper end of the container, and an upper surface of the lower dent and the inner wall of the surrounding wall above the lower dent. and the step portion across the, is provided, the inner peripheral surface of the outer pot by the lower recessed portion when fitted to the outer pot outer peripheral surface of the upper side while the entire circumference to face contact than said lower recess There the water reservoir as possible formed between the parts, and the said surrounding wall, toward over between the upper and lower and fitted into height than upper end position to the outer pot and the lower recessed portion to the container inwards An upper dent portion that is recessed in a vertical stripe shape that is thinner than the lower dent portion is provided, and the upper dent portion allows the inside of the water storage portion to be circulated outside the container.

It is preferable that the surrounding wall is provided with a submerged display portion at a height position higher than the upper end of the slit and lower than the upper limit position of the lower recessed portion.
It is preferable that the slits are provided at a plurality of locations that are evenly arranged in the circumferential direction around the container, and the lower dent portion is provided between the slits.
Of the surrounding walls surrounding the bottom portion, at least the surrounding wall in which the upper recessed portion is arranged is formed so as to protrude above the non-porous surrounding wall of the exterior pot when fitted into the exterior pot. It should just be what has been done.

Specifically, the surrounding wall that protrudes upward from the non-porous surrounding wall of the exterior pot is formed as an upwardly protruding upper edge protruding portion that develops on both sides of the center of the upper recessed portion as a symmetric axis. It should be.
The outer pot is combined with the outer pot and configured as a double pot with an inner / outer double specification, and the outer pot is formed with a non-perforated bottom and a non-perforated container that rises around the outer perimeter of the non-perforated bottom and opens at the top. It is good to have a surrounding wall.

  The exterior pot is preferably formed of a transparent or translucent material that allows the inside of the non-porous enclosure wall to be visually recognized from the outside.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 10 show a first embodiment of a seedling pot 1 according to the present invention. As shown in FIGS. 1 and 2, the seedling pot 1 of the first embodiment is inserted into the exterior pot 2, so that a seedling pot (internal / external double specification) composed of the seedling pot 1 and the exterior pot 2 ( (Hereinafter referred to as “double pot 3”).

  As shown in FIGS. 4 to 9, the seedling pot 1 is a container having an upper opening (having an upper opening 4), a bottom part 5 forming a portion corresponding to the bottom of the container, and an outer peripheral part of the bottom part 5 And a surrounding wall 6 that rises all around. The seedling pot 1 can be formed by blow molding, vacuum molding, or the like using a soft resin such as polyethylene, polyvinyl chloride, or polypropylene.

In the first embodiment, the upper opening 4 has a substantially square shape (the four corners are arc-shaped), and the surrounding wall 6 has four flat wall portions 6a to 6d. . Moreover, each wall part 6a-6d inclines and is formed so that it may spread outward as the upper direction.
The bottom portion 5 is formed in a cross shape having a diagonal line thicker than a substantially square formed by the upper opening 4. A circular water passage hole 7 is formed in the center of the bottom portion 5 so as to penetrate vertically and communicate with the inside and outside of the container.

The surrounding wall 6 has a slit 8 that reaches the lower end (that is, the bottom 5), a lower recess 9 that is disposed so as to be inconsistent with the slit 8 in the circumferential direction around the container, and the lower recess 9 An upper recess portion 10 that reaches the upper end of the surrounding wall 6 at a position that matches at least one of them is provided.
The slit 8 not only penetrates the surrounding wall 6 in the thickness direction, but also extends in the thickness direction with respect to the bottom portion 5 so as to extend radially inward from the outer peripheral position thereof. It is formed to penetrate. However, the slit 8 is stopped at a position away from the water passage hole 7 and does not communicate with the water passage hole 7. That is, the slit 8 is formed in an L shape when viewed from the side cross section, and the inside and outside of the container communicate with each other in the longitudinal direction of the slit 8. Further, the upper end portion of the slit 8 on the side of the surrounding wall 6 is in a range that does not reach the middle of the surrounding wall 6 in the height direction, preferably about 1/3 of the total height from the bottom portion 5 or less (lower). Are arranged as follows.

Such slits 8 are provided at a plurality of locations that are equally arranged in the circumferential direction around the container. In the first embodiment, two pairs of diagonal positions (a corner formed between the walls 6a and 6b, a corner formed between the walls 6b and 6c, and a corner formed between the walls 6c and 6d). A total of four corners formed between the corners and the walls 6d and 6a).
In addition, the specific numerical value regarding the length of this slit 8, a width | variety, etc. is not specifically limited. Also, the arrangement and the number of formations in the circumferential direction around the container are not particularly limited. For example, it may be 1 to 3 around the container, or 5 or more. However, if the slit width of the slit 8 is too narrow or the number of formation is too small, there is a risk that the flow of water or the like through the slit 8 will be insufficient.

  On the contrary, if the slit width is too wide or the number of formations is too large, the culture soil put into the seedling pot 1 spills out through the slit 8, or the surrounding wall 6 is so soft that it cannot hold the container shape. There is a risk of becoming. Therefore, it is necessary to consider the size and arrangement of each part of the slit 8 while correlating with the material and thickness of the surrounding wall 6 and the container shape so that these problems do not occur.

The lower recessed portion 9 is configured such that an approximately lower half portion (downward from a height position exceeding the upper end of the slit 8) of the surrounding wall 6 is recessed into the vessel inward into the vessel, and the lower end thereof is The bottom 5 is reached.
The lower dents 9 are also provided at a plurality of locations that are evenly arranged in the circumferential direction around the container. In the first embodiment, the four wall portions 6a to 6d are provided respectively. Thereby, as mentioned above, the bottom part 5 exhibits a cross shape. That is, each lower recessed portion 9 is disposed between the slit 8 and the slit 8.

The dent distance generated between the upper end of the lower dent 9 and the inner surface of the surrounding wall 6 on the upper side of the lower dent 9 is determined by a step provided so as to extend along the radial direction of the container. It is connected. In the first embodiment, the stepped portion is formed by an upper step 12a that bends in a stepped manner toward the inside of the container on the inner surface side of the surrounding wall 6, and a slant from the lower end of the upper step 12a toward the inside of the container. It is shown as having a pos- sibly lower step 12b on the upper end of the lower recessed portion 9 I Oremaga to.

In addition, the lower recessed portion 9 has a shape as viewed from the front (see FIGS. 5 and 6) and has a divergent shape in which the lateral width on the lower side is wider than the lateral width on the upper side.
By providing the upper step 12a and the lower step 12b in this way, the lower recess 9 itself can be reinforced, and accordingly, the corners of the walls 6a to 6d that are sandwiched by the lower recess 9 are provided. The part can also be reinforced indirectly. In addition, since the lower step 12b is slanted toward the inside of the container and the lower recess 9 is shaped like a divergent shape, when the culture soil is put into the seedling pot 1 or irrigated, the culture soil and water are It is possible to obtain an effect of spreading to the central portion on the bottom portion 5 (upper portion of the water passage hole 7) and the corners on the bottom portion 5 (the projecting end portions of the cross).

The upper dent portion 10 is formed so as to be recessed in a vertical stripe shape thinner than the lower dent portion 9 with the upper and lower portions of the lower dent portion 9 and the upper opening 4 directed inward of the container. The upper recessed portion 10 passes through to the upper end of the surrounding wall 6, and thereby the upper and lower portions between the lower recessed portion 9 and the upper opening 4 communicate with each other in a state of being transmitted along the wall surface of the surrounding wall 6. It has become. In the first embodiment, the upper recessed portion 10 is provided with respect to a set of opposing surfaces (two locations of the wall portions 6b and 6d).

On the other hand, as shown in FIG.1 and FIG.2, the exterior pot 2 used when making the seedling pot 1 as a double pot 3 opened the upper part similarly to the seedling pot 1 (it has the upper opening 20). It is a container, and has a non-porous bottom portion 21 that forms a portion corresponding to the bottom of the container, and a non-porous surrounding wall 22 that rises around the entire outer periphery of the non-porous bottom portion 21.
The non-porous bottom portion 21 and the non-porous surrounding wall 22 are literally configured to have no holes, and water can be stored in a container formed by the non-porous bottom portion 21 and the non-porous surrounding wall 22. The exterior pot 2 can be formed by blow molding, vacuum molding, or the like, using a soft resin such as polyethylene, polyvinyl chloride, or polypropylene, as in the seedling pot 1. However, as the soft resin to be employed, it is preferable to select a transparent or translucent material that can visually recognize the inside of the non-porous wall 22 from the outside. Needless to say, “transparent to translucent” means not only colorless and transparent but also translucent or colored and transparent.

  The exterior pot 2 can fit the seedling pot 1 in a state free from rattling, and at this time, the outer peripheral surface (walls 6a to 6d) above the lower recessed portion 9 of the seedling pot 1 and the entire circumference Surface contact is possible. In other words, the shape and size of the upper opening 20 formed by the non-porous surrounding wall 22, the height of the non-porous surrounding wall 22, and further, so as to obtain such a fitting situation with respect to the seedling pot 1. The planar size of the hole bottom 21 is determined.

  When the seedling pot 1 is fitted into such an exterior pot 2, a water storage section 25 is formed between the lower recessed portion 9 of the seedling pot 1 and the lower portion of the inner peripheral surface of the exterior pot 2. . Moreover, since the upper recessed part 10 of the seedling pot 1 is arranged so that the upper end part exceeds the fitting height to the exterior pot 2, this water storage part 25 is the upper recessed part of the seedling pot 1. The unit 10 communicates with the outside air above the container (not a vacuum-like sealed space). Thereby, the water stored in the water reservoir 25 can be freely distributed over the inside and outside of the seedling pot 1.

In addition, as shown in FIG. 1, it is preferable to provide the infiltration display part 27 in the surrounding wall 6 of the seedling pot 1. This submerged display part 27 is preferably arranged at a height position that is higher than the upper end of the slit 8 and lower than the upper limit position of the lower recess 9. By doing in this way, the appropriate amount of water injection can be easily known from the outside of the exterior pot 2 at the time of irrigation.
In the first embodiment, the inundation display unit 27 is illustrated as an arrow indicating the lower end of the lower step 12 b of the lower recess 9. Therefore, if irrigation is performed according to the inundation display part 27, an air reservoir is formed above the water surface of the water storage (a height region corresponding to the lower step 12b) as the water storage part 25 formed by the lower recessed part 9. You can also. The submerged display unit 27 can be easily understood by the user if a character notation such as “water is here” is also added.

The submerged display portion 27 can be applied by convex or concave characters, printing or imprinting performed at the same time as molding, sticking of a printed seal, or the like.
Although illustration is omitted, a water immersion display portion may be provided in the same manner for the non-porous wall 22 of the exterior pot 2. In this case, it is preferable to arrange the submergence display unit provided in the outer pot 2 and the submergence display unit 27 provided in the seedling pot 1 so that they match when the seedling pot 1 is fitted into the outer pot 2. Thereby, even when the surrounding wall 6 of the seedling pot 1 and the flooded display part 27 become dirty and difficult to see, an appropriate water injection amount can be known by the flooded display part of the exterior pot 2.

  As is clear from the above detailed description, in the seedling pot 1 according to the present invention, the culture pot 1 is put in the container, and the seedling pot 1 is placed in the outer pot 2 in a state where plant seeds, bulbs or seedlings are planted. Fit in and make the double pot 3. Of course, after the seedling pot 1 is fitted into the outer pot 2 to form the double pot 3, the culture soil may be put into the seedling pot 1 to plant a plant.

In addition, it will replace with the exterior pot 2 if it is a container which can be inserted into the seedling raising pot 1 while making the outer peripheral surface (wall parts 6a-6d) above the lower dent part 9 contact the whole surface. Ordinary cups can be used.
After the double pot 3 is configured, watering is performed into the seedling pot 1. By this irrigation, water that has passed through the culture soil oozes into the exterior pot 2 through the water passage hole 7 and the slit 8 of the seedling pot 1. Thereby, water accumulates in the water storage part 25 formed between the lower recessed part 9 of the seedling pot 1 and the exterior pot 2, and the water level comes to rise.

The amount of water injection is adjusted so that the water level rises up to the inundation display unit 27 while using the inundation display unit 27 of the seedling pot 1 as a guide when viewed from the outside of the exterior pot 2 (the exterior pot 2 is provided with an inundation display unit. In such a case, the water immersion display part of the exterior pot 2 may be used as a guide).
If water accumulates up to the position indicated by the inundation display unit 27, the culture soil is always in a state where water can be absorbed through the water passage hole 7 and the slit 8, so that the water in the water storage unit 25 disappears and the culture soil is dried. During a considerable period of time (for example, for 1 month or 2 months), the plant received in the seedling pot 1 does not wither due to running out of water.

  Therefore, an epoch-making advantage that the labor of irrigation can be omitted in this considerable period can be obtained. Further, since the irrigated water does not leak out of the exterior pot 2, the surroundings are not soiled. These advantages can be said to be extremely useful in the point that, for example, in the store, manual intervention during the display for sale can be thoroughly reduced, and the beauty in the store is not harmed.

  As described above, the water storage unit 25 communicates with the outside air above the container through the upper recess 10 of the seedling pot 1, so that the water accumulated in the water storage unit 25 is always kept under atmospheric pressure and can be respired. Since it is in a state, the phenomenon of water absorption from the water storage unit 25 to the culture soil, and the phenomenon that water oozes out from the culture soil to the water storage unit 25 by subsequent irrigation is always performed smoothly. That is, the advantage that the irrigation work can be omitted over a considerable period of time is reliably maintained.

  The seedling pot 1 according to the present invention is not limited to exhibiting for the production and sale of plants after the exterior pot 2 is used to form the double pot 3. For example, only the seedling pot 1 is used for production or sales display, and the irrigation pot 2 is fitted into the seedling pot 1 at the time of actual sales while performing short-term and regular irrigation as before. It is also possible to adopt a method of use such as handing over.

  Also in this case, the purchaser can decorate indoors with the exterior pot 2 fitted at home or the like (as a double pot 3), so that it is possible to save time for irrigation over a considerable period of time. The benefits are of course obtained. Moreover, since the irrigated water does not leak out of the exterior pot 2, the advantage that the surroundings are not soiled is naturally obtained.

  FIG. 10 shows a process of manufacturing the seedling pot 1 according to the present invention by blow molding (hollow molding). As shown in FIG. 10, when the seedling pot 1 is manufactured by blow molding, a hollow molded body 30 is formed in which the seedling pot 1 and the exterior pot 2 face each other. After taking out from the mold | types 31 and 32, the procedure of dividing | segmenting into a seedling pot (1) and an exterior pot (2) is employable.

  That is, if the outline of the hollow molding procedure is outlined, molten resin is injected from one end side of the molds 31 and 32 (left side in FIG. 10), and a thick cylindrical body (parison) is first formed in the molds 31 and 32. The pressure nozzle 33 is inserted into the parison from the other end of the molds 31 and 32, and compressed air is blown from the pressure nozzle 33 to press the parison into the molds 31 and 32. And the metal mold | dies 31 and 32 are opened and the molded object 30 in it is taken out. In the removed molded body 30, the nozzle hole 35 associated with the insertion and removal of the pressure nozzle 33 is inevitably left together with the unnecessary piece 34 as an injection mark of the molten resin.

Therefore, if the side where the nozzle hole 35 is generated is the seedling pot (1) and the other side is the exterior pot (2), the seedling pot (1) is aligned with the nozzle hole 35. Thus, the water flow hole 7 of the bottom portion 5 is formed, and the unnecessary piece 34 is simply deleted from the exterior pot (2).
That is, the procedure for manufacturing the molded body 30 in which the seedling pot 1 and the exterior pot 2 are paired in this way is the production of a molded body in which the exterior pots 2 (containers having the non-porous bottom portion 21) face each other. It is possible to eliminate the inconvenience that it is not possible (manufacturing itself is possible, but even if such a molded body is manufactured, half must be discarded because of the nozzle holes 35). Moreover, compared with the case where the molded object which made the seedling pots 1 face each other is manufactured, it can be said that it leads also to the advantage that the effort of a process (process which forms the water flow hole 7) is reduced by half.

  11 and 12 show a second embodiment of the seedling pot 1 according to the present invention. The seedling pot 1 of the second embodiment is configured to obtain high strength by changing the type of material used, setting of the wall thickness, and the like. Since the strength is increased, the upper peripheral portion of the surrounding wall 6 is formed in a plane. Similarly, the upper peripheral part of the non-porous wall 22 is also formed in a planar manner for the exterior pot 2.

  That is, in the first embodiment (FIGS. 1 to 9), the upper peripheral portion of the surrounding wall 6 in the seedling pot 1 and the upper peripheral portion of the non-porous surrounding wall 22 in the exterior pot 2 also serve as reinforcement. Although the horizontal striped ribs 37 and 38 are provided, these ribs 38 and 38 are omitted in the second embodiment. As a result, the dies 31 and 32 used for blow molding or the like can have a simple structure, which contributes to cost reduction.

FIG. 13 thru | or FIG. 19 has shown 3rd Embodiment of the seedling raising pot 1 which concerns on this invention. The seedling pot 1 of the third embodiment is obtained by further improving the seedling pot 1 in order to further enhance convenience when it is fitted into the exterior pot 2 and used as the double pot 3. Improvement to the exterior pot 2 is also recommended.
That is, in the seedling pot 1 of the third embodiment, when used as the double pot 3, the surrounding wall 6 in which the upper recessed portion 10 is arranged protrudes above the non-porous surrounding wall 22 of the exterior pot 2. It has become. Due to this upward protrusion, the upper end portion of the upper recessed portion 10 provided corresponding to the upper end position of the surrounding wall 6 is also exposed upward beyond the height of the exterior pot 2. .

  Therefore, even if the upper end portion of the upper dent portion 10 is crushed or clogged with culture soil, the entry and exit of air into the upper dent portion 10 is not hindered. As a result, the water accumulated in the water storage unit 25 is always maintained under atmospheric pressure, so that water is oozed out from the culture soil to the water storage unit 25 by water absorption from the water storage unit 25 to the culture soil and subsequent irrigation. It is guaranteed that it is always performed smoothly.

  In the example of FIGS. 13 to 19 given as one of the specific structures for obtaining such an operational effect, at least the upper recess 10 is arranged in the surrounding wall 6 provided with the upper recess 10. The upper edge overhanging part 45 is provided in the part. The upper edge overhanging portion 45 is formed in an upwardly convex arc shape that develops on both sides with the center of the upper recessed portion 10 as the axis of symmetry, and the seedling pot 1 is fitted into the outer pot 2. In some cases, the upper edge protruding portion 45 protrudes upward from the upper edge portion of the exterior pot 2. The upper edge projecting portion 45 is not limited to an arc shape, and may be formed as an angular convex shape, a triangle, or the like.

  In order to form the upper edge overhanging portion 45 for the seedling pot 1, the following procedure is performed. That is, as shown in FIG. 19, in blow molding when manufacturing the seedling pot 1, a hollow body 30 is formed in which the seedling pot 1 and the exterior pot 2 face each other. When dividing from 30 into the seedling pot 1 and the exterior pot 2, the incision line is curved in the middle so that the upper edge overhanging portion 45 remains on the surrounding wall 6 side of the seedling pot 1.

  If it does in this way, the recessed part 46 used as the circular arc shape dented below with respect to the upper edge part of the non-porous surrounding wall 22 will be formed in the exterior pot 2. As shown in FIG. Therefore, as shown in FIG. 18, when the state in which the seedling pot 1 is fitted into the exterior pot 2 is viewed from the side, the upper edge overhanging portion 45 of the seedling pot 1 and the recess 46 of the exterior pot 2 match. Also, the wrinkle has a vertically symmetrical curved shape like the cross section of the convex lens, and the surrounding wall 6 of the seedling pot 1 (the place where the upper end portion of the upper recessed portion 10 is disposed) is exposed outward.

For this reason, in the seedling pot 1, it is not necessary to extend the upper edge overhanging portion 45 excessively upward. Therefore, the design is refreshing in appearance, and it does not make the viewer feel uncomfortable. Moreover, when providing the upper recessed part 10 so that it may reach to the upper end of the upper edge overhang | projection part 45, since it is not necessary to penetrate this upper recessed part 10 upwards (an upper end part may be obstruct | occluded), division | segmentation position There is no need to carefully position (with high accuracy).

  In addition, the outwardly exposed portion by the surrounding wall 6 of the seedling pot 1 obtained at the place where the upper edge projecting portion 45 of the seedling pot 1 and the recess portion 46 of the exterior pot 2 coincide with each other is a narrow jug or rain dew. It can also be used as a part for irrigation by (watering). If such an irrigation method is taken, compared to the case where the cultivated soil (plant root) in the seedling pot 1 is directly irrigated, the effect that the surface of the cultured soil is not roughened and the effect that the irrigation is less likely to overflow. Furthermore, it is preferable because it leads to an effect that there is no fear of weakening the plant by irrigation.

  The specific structures shown in FIGS. 13 to 19 are merely examples. For example, as shown in FIG. 20 as a fourth embodiment, when the blow molded hollow body 30 is divided into the seedling pot 1 and the exterior pot 2, the center position relative to the total length L of the molded body 30 (in the drawing) The length L1 corresponding to the height of the seedling pot 1 and the length corresponding to the height of the exterior pot 2 A position where the relationship with L2 satisfies L1> L2 may be set as a division position.

  By adopting this dividing position, when the seedling pot 1 is fitted into the exterior pot 2, the surrounding wall 6 in which the upper recessed portion 10 is arranged in the seedling pot 1 is more than the non-porous surrounding wall 22 of the exterior pot 2. Since it protrudes upwards, the upper end part of the upper recessed part 10 will necessarily be exposed above the height of the exterior pot 2 inevitably. Naturally, in this case, it is not necessary to provide the upper edge overhanging portion 45 in the seedling pot 1, so that the division can be easily performed, and there is an advantage that leads to cost reduction.

By the way, this invention is not limited to each above-mentioned embodiment, It can change suitably according to embodiment.
For example, the seedling pot 1 and the exterior pot 2 may have an inverted truncated cone shape (a cylindrical shape in which the bottom 5 and the non-porous bottom 21 are circular and the surrounding wall 6 and the non-porous surrounding wall 22 are constricted).
In the first embodiment (FIGS. 1 to 9), the slit 8 may be provided in the walls 6a to 6d. In this case, the lower recessed portion 9 may be provided at a diagonal portion such as a corner portion formed between the wall portions 6a and 6b or a corner portion formed between the wall portions 6c and 6d.
