Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating cover for a flower pot, which is suitable for keeping the root of a plant cultivated in the flower pot.

[0002]

2. Description of the Related Art In a conventional unglazed flowerpot or a synthetic resin flowerpot, the soil and the outside air in the flowerpot are only separated by a single unglazed or synthetic resin wall. Was significantly affected by changes in outside temperature. Especially in unglazed flowerpots, the temperature difference of soil between daytime and nighttime was large because air flowed in and out through the unglazed wall.

[0003]

It is known that a change in soil temperature in a flower pot has a significant effect on root development. If the roots can grow smoothly, the trunk and leaves can grow large, and those with flowers will have a large number of flowers and a large flower size. However, a drastic change in soil temperature adversely affects the growth of roots and hinders the successful growth of plants. Desirably, the soil temperature should be kept constant day and night. Also, there are cases where it is desired to keep the soil temperature high even in winter.

However, conventional unglazed flowerpots or synthetic resin flowerpots have not been able to maintain the soil temperature to some extent. This is because heat transfer occurs through those wall surfaces. Especially in unglazed flower pots, penetration of outside air occurs. An object of the present invention is to solve such a problem.

[0005]

The above object is achieved by providing a cover that can be attached to the outside of a flowerpot as described below. That is, the cover is made of a foam, has a gap between the flowerpot and the cover, and has a structure in which at least the space between the upper edge of the flowerpot and the upper edge of the cover is closed. .

Further, in the invention of claim 2, according to claim 1, the cover is a molded body such as styrene foam.

According to a third aspect of the present invention, in the first aspect, the cover is formed of a flexible sheet.

According to a fourth aspect of the present invention, in the first aspect, the cover is formed so that a space between the flowerpot and the cover can be made a completely closed space. It was assumed that.

According to a fifth aspect of the present invention, in the first aspect, a water supply port is provided in a part of the cover.

According to a sixth aspect of the present invention, in the first aspect, the cover is colored.

[0011]

Since the cover for covering the flower pot is made of a foam, each of the bubbles stores air, so that the temperature of the entire cover can be kept constant. Since there is a gap between the flowerpot and the cover, the temperature of the air in the gap is also kept constant. At this time, since at least the space between the upper edge of the flowerpot and the upper edge of the cover is closed, the air in the gap and the outside air do not exchange with each other. As a result, the flowerpot itself is kept warm, the temperature of the soil in the flowerpot is kept constant to some extent, and this has a good effect on root growth.

Since there are substantially two layers of air that are isolated from the outside air in this way, not only the heat retention but also the moisture retention effect is produced.

Further, the invention according to claim 2 is characterized in that the cover is a molded body such as styrene foam.
According to this, a solid outer wall can be formed around the flowerpot, and the effect of not only keeping heat but also protecting the flowerpot is produced. The shape and the like can be freely molded.

According to a third aspect of the present invention, the cover is formed of a flexible sheet. According to this, not only the effect of keeping the flower pot warm, but also the effect of being able to cover the periphery of the flower pot flexibly and decorate the flower pot is produced.

In the invention of claim 4, the cover is formed so that the space between the flowerpot and the cover is a space completely closed only by the cover.
The heat retaining effect is further improved. That is, in the case of a structure in which the space between the upper edge of the flowerpot and the upper edge of the cover is closed but the bottom of the cover is removed, the flowerpot and the cover may be directly placed on the floor or placed on a tray. When placed, the space between the lower edge of the flowerpot and the lower edge of the cover is closed by the floor or the tray, so that a layer of air blocked from the outside air is formed. Instead of relying on it, you can block the bottom yourself. With this configuration, the heat retaining effect is further improved because the surface structure of the floor on which the flowerpot and the cover are placed is not affected.

According to a fifth aspect of the present invention, a water supply port is provided in a part of the cover. The water supply port is connected to a water source so that water can be automatically supplied to the soil. This portion of the cover is substantially shut off from outside air by a connecting hose or the like.
In addition, assuming that a water supply port is not used, it is also preferable to adopt a configuration in which a cap can be attached to this port.

In the invention according to claim 6, the cover is subjected to a coloring treatment. In both the second and third aspects of the invention, the cover can be colored. This may be a single color, or a picture or the like may be printed. In any case, it contributes to improving the appearance of the cover.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings, but the present invention is not limited only to these embodiments.

FIG. 1 shows a first embodiment of the present invention. The cover 2 as a molded article of foamed polystyrene is a substantially cylindrical body, and has a size of the mounting port 25 such that the close contact portion 20 is formed when the flowerpot 1 is mounted from the mounting port 25 therein. . The height of the cover 2 is set to be larger than the height of the flower pot 2 so that the space 3 is formed between the inside of the cover 2 and the flower pot 1. As can be seen from FIG. 2, the cover 2 contains a myriad of air bubbles 22.

When the flower pot 1 is mounted from the mounting opening 25 of the cover 2, the upper edge of the flower pot 1 and the upper edge of the cover 2 are in close contact with each other at the contact portion 20, and the lower edge of the cover 2 is on the floor. The gap 3 is formed as a closed space between the cover 2 and the flowerpot 1 so that the air in the gap and the outside air do not exchange with each other. The outside air, which is the atmosphere of the cover 2, is blocked by the myriad of air bubbles 22 of the cover 2 and the voids 3 as apparent from FIG. 2. That is, the air in the air bubbles 22 is hardly affected by the temperature change of the outside air, and the air in the gap 3 which is the inner air layer is hardly affected by the temperature change of the outside air.

Since the flowerpot 1 is protected by the double air layer (heat insulation layer), the temperature of the flowerpot 1 itself is maintained, the temperature of the soil in the flowerpot is maintained at a certain level, and it is good for root growth. It has an effect.

FIG. 3 shows a second embodiment, which differs from the first embodiment in that the cover 4 is formed of a flexible foam sheet. The cover 4 is formed in a cylindrical shape so as to cover the flowerpot 1 loosely, and has a rubber ring 42 inserted in an upper edge portion and a lower edge portion thereof.

The lower edge of the cover 2 and the lower edge of the cover 2 closely contact each other at the contact portion 41, and the gap 3, which is a closed space between the cover 4 that covers the flower pot 1 and the flower pot 1, is formed. Void 3
The inside air and outside air cannot be exchanged. In addition, the cover 4 itself contains a myriad of air bubbles 22 and serves as a heat insulating layer.

FIG. 4 shows a third embodiment of the present invention. Although the basic configuration is similar to that of the first embodiment, this embodiment is different from the first embodiment in that a bottom 23 is provided. The contact portion 21 is formed by contact between the flower pot 1 and the bottom portion 23. Similarly, the contact portion 20 is formed by contact between the flowerpot 1 and the upper edge of the cover 2. Reference numeral 3 denotes a gap created in this manner. In addition, a hole 24 is opened at the center of the bottom 23. The hole 24 can be used as both a drain port and a water supply port. For the use as a water supply port, see the description of the sixth embodiment.

FIG. 5 shows a fourth embodiment. Although the basic configuration is similar to that of the first embodiment, this embodiment is different from the first embodiment in that a bottom portion 23 is provided. Different from the three embodiments. That is, the flowerpot 1 covers the side periphery and the bottom thereof.
The structure of claim 4 is realized, and the bottom is closed by the cover 2 itself instead of relying on the floor or the tray. With this configuration, since the surface structure of the floor on which the flowerpot 1 and the cover 2 are placed is not affected, the heat retaining effect of the gap 3 is further improved. In FIG. 5, the bottom portion 23 is recessed. However, the bottom portion 23 may be formed deeper to form a water receiving portion.

FIG. 6 shows a fifth embodiment of the present invention. This embodiment is characterized in that three components of the fourth embodiment are arranged in parallel. According to the plan view of FIG. 6, three mounting ports 25 are opened in the substantially rectangular cover 2.
