Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a water hole and a vent hole of a flowerpot.

(Prior art and its problems) The water hole of a flowerpot is classically a round hole that is relatively large, one in the center of the bottom of the pot.

Since pottery flower pots have appropriate breathability due to their material, so-called root rot is less likely to occur, but recent synthetic resin plant pots have little breathability compared to conventional plant pots. Therefore, there is a problem that root rot is likely to occur.

The root rot is caused not only by breathability but also by poor drainage.

The first conceivable way to solve this problem would be to enlarge the round hole at the bottom to improve drainage.

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

However, the enlargement of the round hole is not only inconvenient because it results in accelerating the outflow of soil in the pot, but it is not possible to form it on the entire bottom in terms of the pot function.

A flowerpot having a structure that eventually compensates for this inconvenience is disclosed in Japanese Patent Application No. 55-52004 (publication No. 55-152962) and Japanese Utility Model Publication No.
It is disclosed in Japanese Patent Publication No. 1-35553 and Japanese Utility Model Publication No. 51-6430.

However, although these structures have some effect in terms of draining water from the pot and breathability of the pot, they are still insufficient from the viewpoint of the proper moisturizing property expected of the flower pot. I can't say.

It is because it is also important for pot cultivation that the soil in the pot is too dry.

It is an object of the present invention to provide a flower pot which can exhibit not only breathability and water permeability but also moisturizing performance.

(Means for Solving the Problem) In order to solve the above problems, the present invention forms the bottom of the flowerpot at a center of the bottom so that the height of the bottom of the flowerpot is higher than the grounding surface It is formed by providing a step with the low bottom part, and a water passage and ventilation hole is provided on the slope part connecting from the high bottom part to the low bottom part, and at the part where the inclined part and the low bottom part are in contact, both parts are opened. A water passage and ventilation hole is provided, and further, a water passage hole is provided at the lower bottom portion in contact with the ground contact surface. The water passage and ventilation hole is an arc-shaped elongated hole, and the arc-shaped elongated hole is inclined with respect to the inclination direction. The configuration is such that they are opened in a direction substantially orthogonal to each other.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

This will be described with reference to FIGS. 1 to 4.

FIG. 1 is a bottom view of the pot, and FIG. 2 is a vertical sectional view thereof.

First, in FIG. 1, reference numeral 10 in the drawing is the bottom portion of the pot, and reference numeral 11 is a water passage and ventilation hole formed in the bottom portion 10.

The water-passage / ventilation hole 11 of the bottom portion 10 shown in the drawing has two arc-shaped line segments along the concentric circle drawn centering on the center of the bottom portion 10 as the long sides, and is the diametrical direction of the concentric circle.
It is formed in an arc-shaped elongated hole whose two short sides are two line segments that respectively connect both ends of each arc-shaped line segment, that is, a fan-shaped deformed rectangular shape. In addition, reference numeral 13 is an air space (surface) in the hole of the arc-shaped elongated hole 11.
The reference numeral 12 indicates the pot bottom portion on the periphery of the arc-shaped elongated hole 11.

The arc-shaped elongated hole 11 has a fan-shaped deformed rectangular shape, and the four corners of the hole inner space 13 are not right angles, and one of two adjacent sides forming the corner is an arc and the other is a straight line. .

Moreover, the two corner angles of the air space 13 in the hole, which are opposed to each other in a substantially diagonal direction, have different opening angles between the arc and the straight line.

When the water passage and ventilation hole is formed in such an arc-shaped elongated hole 11, that is, a fan-shaped deformed rectangular shape, the inner peripheral edge of the hole inner space 13 that becomes a foothold of the water film even if the tension of water acts Since the morphology is different from the opposite edges, the tension is not balanced and therefore
A film is less likely to be generated.

Further, since the arc-shaped elongated holes 11 having such a shape are formed along the concentric circles centered on the center of the flowerpot bottom 10, a part of the bottom 10 is formed in large numbers over the entire surface of the bottom 10. Therefore, the structural strength of the bottom portion 10 can be sufficiently maintained.

Then, by appropriately setting the interval between the two arcs and the curved portion, a large water-cum-vent hole of the hole space 13 through which only air or water is passed is arranged while preventing the outflow of soil in the pot. be able to.

In FIG. 2, the bottom portion 10 of the illustrated flower pot has a high bottom portion 10A formed high in the center of the pot bottom from the ground contact surface, and a low bottom portion formed on the outer edge side of the pot bottom to contact the ground contact surface. The bottom portion 10C is provided, and the high bottom portion 10A and the low bottom portion 10C are provided with a step.

The illustrated high bottom portion 10A occupies a central region of the bottom portion 10, and the low bottom portion 10C is formed so as to occupy an annular region on the outer edge side of the bottom portion 10.

The high-bottom portion 10A is provided with a hole 14 having an appropriate shape as a water-passing hole.

Further, the arc-shaped elongated holes 11 are arranged at appropriate intervals also in the low bottom portion 10C.

In this way, the high bottom portion 10A is formed in the central region of the bottom portion 10,
When the low bottom portion 10C is formed in the annular region of the outer edge, at the time of water injection, the water poured into the pot comes into the soil and then gathers in the low low bottom portion 10C, and is appropriately formed in the annular region. It is discharged from the inner space 13 of the arc-shaped elongated hole 11.

Therefore, although the hole 14 formed in the high bottom portion 10A formed in the central region of the bottom portion 10 also functions as a water passage hole, it mainly functions as a ventilation hole.

If the bottom 10 has a flat surface as a whole, the poured water naturally spreads over the bottom 10 and the pores are blocked until the water drains out, impairing the air permeability of the soil.

In order to make the water drainage better and to ensure air permeability, a step portion having a height difference is provided on the bottom portion 10 of the flowerpot as described above,
Ventilation and ventilation holes (11, 13, 14) are provided at the high position (high bottom part 10A) and the low position (10C), respectively, to provide a passage for air that enters the soil instead of the water discharged from the soil. It is good to secure it.

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

This not only secures water permeability and air permeability at the same time when water is injected, but also prompts the intrusion of air pressure into the soil to accelerate the drainage of water from the soil, resulting in more rapid drainage. To be done.

Therefore, it is possible to more effectively prevent the occurrence of root rot due to drainage of water and poor drainage.

In the example shown in FIG. 5 (A), the above-mentioned arc-shaped elongated hole 11 is inclined to the slope portion 10B connecting from the high bottom portion 10A of the bottom portion 10 provided with steps to the low bottom portion 10C not in contact with the ground plane. This is an example provided in a direction substantially orthogonal to the direction. Further, in the embodiment shown in FIG. 5B, the above-mentioned arc-shaped elongated hole 11 is
This is an example provided in a region continuous from 10B to the low bottom portion 10C in contact with the ground plane, that is, in a region extending from the inclined portion 10B to the low bottom portion 10C in a direction substantially orthogonal to the inclination direction.

Thus, not only the inclined portion 10B between the steps but the inclined portion 1
When the arc-shaped elongated hole 11 (13, 13A) is formed in the area extending from 0B to the low-bottom portion 10C in contact with the ground plane, that is, in the area extending from the bottom portion bulged to function as the foot of the pot to both portions,
Since the holes 13 and 13A in the holes are made to extend along the vertical direction instead of horizontally, the water poured into the flowerpot comes into contact with the ground surface especially in the holes 13A. Instead of staying in the low bottom portion 10C, it is promptly discharged to the central empty space 21 and discharged quickly.

Further, by providing the arc-shaped elongated hole 11 whose width is extremely narrow with respect to the length in a direction substantially orthogonal to the inclination direction, while preventing the outflow of soil in the pot, the area of the hole space 13, 13A Can be formed large.

As in the past, for simple holes, such as round or oval holes,
The water film is easily formed due to the surface tension of the water, and a large space is created in the center of the air space inside the hole, so that the soil easily flows out.However, the present invention eliminates such inconvenience. Will end up.

Further, a water passage hole, for example, an arc-shaped elongated hole 11 is provided in a low bottom portion in contact with the ground contact surface, and the flower pot is placed directly on the ground or a mat for hydroponics, or water for hydroponics or a pot If the soil in the pot contacts the ground, mats, or water directly through the water passage holes, the soil in the pot will dry. Water is naturally absorbed from these to maintain appropriate humidity, and it is possible to prevent withering due to drying.

In FIGS. 1, 3, and 4, reference numeral 20 is a drainage / ventilation hole formed by recessing the back surface side of the bottom portion 20 in an arch shape. Such ventilation and drainage holes 20 are provided on the outer peripheral edge side of the bottom portion 10 in a radial manner from the bottom of the high bottom portion 10A toward the outer edge in order to communicate the central empty portion 21 which is the back space of the high bottom portion 10A to the outside. is there.

The ventilation and drainage hole 20 is a hole for guiding the water discharged to the rear surface side of the bottom portion 10 to the outside from the bottom of the pot in a state where the pot is placed, but this is the central empty space at the same time. It also functions as a ventilation passage for the outside air to pass through.

(Effect of the Invention) According to the present invention, the arc-shaped elongated hole is formed not only in the inclined portion between the steps but also in the area extending from the inclined portion to both the low bottom portion in contact with the ground plane. The water poured into the flowerpot is discharged without staying in the low bottom part, while the water hole is provided in the low bottom part in contact with the ground contact surface, so the flowerpot can be placed directly on the ground or on a mat for hydroponics. When the soil in the pots dries through the water passage holes, the water will naturally evaporate by placing them in the water for hydroponics or in the reservoir of the saucer for the flowerpot. It is possible to provide a flowerpot that absorbs and keeps an appropriate amount of moisture to prevent dying due to drying, and has ideal water / air permeability and an appropriate amount of moisture retention.
