Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to the shape of a water passage/ventilation hole in a flower pot.

(Prior art and its problems) The shape of the water hole in a flowerpot is one in the center of the bottom of the pot.
A classic example of this is a relatively large round hole.

Ceramic flowerpots have adequate ventilation due to their material, so so-called root rot is less likely to occur.
Modern synthetic resin flower pots have almost no air permeability compared to conventional flower pots, so they are susceptible to root rot.

Root rot is caused not only by poor ventilation but also by poor drainage.

The first thing that comes to mind to solve this problem is to enlarge the round hole at the bottom to improve drainage.

This is because the larger the round hole, the better the air permeability and water permeability, that is, the drainage of water.

However, enlarging the round hole is not only inconvenient as it encourages the soil inside the pot to flow out, but it is also impossible to form it over the entire bottom of the pot due to the functionality of the pot.

Regarding this problem, Utility Application No. 56-24614 (Utility Model Application No. 58-30440) and Utility Application No. 59-18221 (Utility Model Application No. 59-18221)
There is an idea shown in drawings such as No. 60-131150).

In all of these ideas, there is not just one round hole,
Tiny square holes are drilled in a fine grid pattern. Incidentally, there is no mention in any of the specifications of the invention that the water passage/ventilation holes are formed in the form of a lattice having countless small square holes.

In this way, a pot bottom with countless tiny square holes formed in a lattice pattern would be more effective in preventing the soil from flowing out than enlarging the round holes. When the soil is dry,
Breathability will also be good.

However, once water is poured into the pores of this shape, the soil may become wet and block the minute pores, soil particles may clog the pores, or surface tension may act on the pores and form a film of water. On the contrary, water permeability and air permeability are impaired.

In other words, drainage becomes poor, the soil retains too much water, and the aeration becomes poor, making root rot more likely.

The present invention was made with the aim of solving this problem.

(Means for Solving the Problem) In order to solve the above-mentioned object, the present invention has a bottom part of the flowerpot that has a central area that is placed high so that the center of the bottom part does not touch the ground, and a peripheral area of the bottom part that is grounded to the ground. and a sloped portion formed in a stepped area between the bottom portion and the central region and extending from the central region at a higher position to the bottom portion at a lower position, and the central region includes: The long sides are two arc-shaped line segments that run side by side along a concentric circle drawn with the bottom as the center, and two line segments that are in the diametrical direction of the concentric circle and connect the short distances of the two arc-shaped line segments, respectively. An appropriate number of water passage and ventilation holes formed in a deformed rectangle with a short side of It is structured as follows.

(Function) In the present invention, the shape of the water passage/ventilation hole is a fan-shaped deformed rectangle, so that the surface tension of water becomes difficult to act on.

In addition, the water passage/ventilation hole of the present invention is a fan-shaped deformed rectangle whose longitudinal axis is bent into an arc, so even if a hole with a large internal area is formed,
It can prevent the soil in the pot from flowing out.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

First, a first embodiment will be explained with reference to FIGS. 1 to 4. FIG. 1 is a bottom view of the pot, and FIG. 2 is a longitudinal sectional view thereof.

In FIG. 1, reference numeral 10 is the bottom of the pot, and reference numeral 11 is a water passage/ventilation hole.

The water passage/ventilation hole 11 has two arcuate line segments running side by side along a concentric circle drawn centering on the center of the bottom part 10 as its long sides, and is in the diametrical direction of the concentric circle.
It is formed into an arc-shaped elongated hole, that is, a fan-shaped deformed rectangular shape, whose short sides are two line segments connecting both ends of the two arc-shaped line segments, respectively.

Note that the reference numeral 13 refers to the internal space (surface) of the arc-shaped elongated hole 11, and the reference numeral 12 refers to the pot bottom portion at the periphery of the elongated hole 11.

The arc-shaped long hole 11 has a fan-shaped modified rectangular shape, and the four corners of the hole space 13 are not right angles, and one of the two adjacent sides forming the corner is an arc and the other is a straight line. . In addition, the two opposing corners of the hole cavity 13 in the substantially diagonal direction have different opening angles between the arc and the straight line.

Such arc-shaped elongated holes 11, ie,
If it is formed into a fan-shaped deformed rectangular shape, even if tension is to be applied, the shape of the inner circumferential edge of the inner hole space 13, which serves as a foothold for the membrane, is different from the opposing edge, so the tension cannot be balanced. As a result, it becomes difficult for a film to form.

Moreover, since the arc-shaped elongated holes 11 having such a shape are formed along concentric circles drawn around the center of the flowerpot bottom 10, not only a part of the bottom 10 but also the entire surface of the bottom 10 are formed. A large number of them can be formed, and the structural strength of the bottom part 10 can also be maintained sufficiently.

By setting the distance between the two arcs and the degree of curvature appropriately, a large water passage/ventilation hole is created in the hole air space 13 that allows only air and water to pass through while preventing the soil inside the pot from flowing out. can be set.

In FIG. 2 and FIGS. 5A and 5B, the structure of the bottom part 10 of the flowerpot is formed as follows.

That is, the center of the bottom part 10 is a flat central area 10A formed at a position higher than the ground so that the bottom does not touch the ground, and the peripheral edge side of the bottom part 10 is a low position where the bottom touches the ground. The flat bottom portion 10C is formed to have a flat bottom portion 10C.

A slope portion 10B is formed in a stepped region between the bottom surface portion 10C and the central region 10A, which extends from the high central region 10A to the low bottom surface portion 10C.

A hole 14 of an appropriate shape is bored in the bottom central area 10A as a water passage and ventilation hole.

In this way, if the central region 10A of the bottom part 10 is formed higher than the annular region at the outer edge, when water is poured,
After the water poured into the pot permeates through the soil, it collects in the lower annular region, and from the hole space 13 of the arc-shaped elongated hole 11 formed appropriately in the annular region.
be discharged.

Therefore, the hole 14 bored in the central region 10A of the bottom part 10 also functions as a water hole, but mainly functions as a ventilation hole.

If the entire bottom part 10 is a flat surface,
The poured water naturally spreads over the entire bottom 10,
Until the water drains out, the pores become blocked and the aeration of the soil is impaired.

In order to improve drainage and ensure ventilation, a step with a difference in height is provided at the bottom 10 of the flower pot as described above, and water and ventilation holes 11, 13 are provided at the high and low positions, respectively. 14 to ensure a passage for air to enter the soil instead of water draining from the soil.

In this embodiment, the inner hole space 13 as the arc-shaped elongated hole 11 serving as a water passage and ventilation hole is provided on the outer edge annular region side of the bottom portion 10 at a low position, and the central region 10A of the bottom portion 10 at a high position is provided. , a hole 14 of an appropriate shape is provided.

This not only ensures water permeability and air permeability at the same time when water is poured, but also promotes the drainage of water within the dojo by allowing air pressure to quickly penetrate into the soil. Water drains more quickly.

Therefore, the occurrence of root rot due to lack of water or poor water drainage can be more effectively prevented.

In FIGS. 1, 3, and 4, reference numeral 20 indicates a drainage/ventilation hole formed by recessing the back side of the bottom portion 20 in an arch shape.

Such ventilation/drainage holes 20 are arranged radially from the central region 10A toward the outer edge in order to connect the central cavity 21, which is the back space of the central region 10A with the raised bottom 10, to the outside world. There are several.

The ventilation/drainage hole 20 is a hole for guiding water discharged to the back side of the bottom part 10 when the pot is placed, further out from the bottom of the pot.
At the same time, it also functions as a ventilation path for passing outside air into the central cavity 21.

A and B in FIG. 5 show still another embodiment.

In this embodiment, a hollow space 13 as an arc-shaped elongated hole 11 is defined by an inclined part 10B that extends from a central region 10A at a high position of a stepped bottom 10 to an annular region at a lower position, and a bottom surface which is a lower annular region. Part 1
In addition to being provided at 0C, there is also an in-hole air space 13A extending from the slope part 10B to the bottom part 10C.
(arc-shaped elongated hole 11) is provided.

As described above, the arc-shaped elongated hole 1
1, 13, and 13A, the hole air space 13,
13A will be extended vertically rather than horizontally, especially in the borehole air space 13A.
In this case, the water poured into the flower pot can be discharged to the central cavity 21 without being retained in the bottom part 10C, and can be quickly discharged from the central cavity 21 to the outside through the ventilation/drainage hole 20. .

FIGS. 6 and 7 show still another embodiment.

In this embodiment, the bottom part 10 of the pot is formed into a hemispherical shape with an upward concave shape, and a plurality of legs 30 are provided on the back surface of the bottom part 10 to support the pot.

Therefore, the central cavity 21 on the back side of the bottom part 10 is formed by the hemispherical bottom part 10 and the plurality of legs 30, and the ventilation/drainage hole 20 through which the central cavity 21 communicates with the outside world is formed by the legs 30. and the leg 30.

(Effect of the invention) According to the invention, since the shape of the water passage/ventilation hole is a fan-shaped deformed rectangle, any point within the hole surrounded by four sides is equidistant from the four sides. , and the two pairs of opposite sides cannot be parallel, making it difficult for the surface tension of water to work.

Therefore, it is possible to prevent the holes from being blocked by a curtain of water, and it is possible to provide a flower pot with better water permeability and air permeability than conventional ones.

In addition, since the water passage/ventilation hole of the present invention has a deformed fan-shaped rectangle whose longitudinal axis is bent into an arc, the interval between the two arcs and the degree of curvature must be set appropriately. This makes it possible to form holes with large internal air spaces, which could not be achieved with a grid shape having simple square holes because it would not prevent soil from flowing out of the pot.

Furthermore, in the flower pot of the present invention, since the arc-shaped long hole for water flow and ventilation is provided from the inclined part to the bottom part, the hole stands vertically rather than horizontally, so that the pot The poured water does not stay at the bottom, but can be efficiently and quickly distributed to the central cavity below the raised central area, making it extremely permeable and breathable compared to conventional pots. can provide excellent flower pots.
