Description of the Related Art Heretofore, as this type of planter, there has been known a planter formed of a rectangular box-shaped main body having an open upper surface and made of a synthetic resin such as polypropylene as a raw material. In such a planter, flowers and plants are planted on a cultivation floor housed in the main body. The planters planted in this way are placed on a flower stand or on the open ground to be viewed.

[0003]

By the way, the ground on which the planter is installed is not always horizontal, but is often inclined. In this case, if the planter is placed on the inclined surface as it is, the planted flowers are in an inclined state, which may impair the appearance. Further, soil excavated with water at the time of watering may spill out from an opening edge on a side which is inclined and lowered, and a root may be exposed. On the other hand, a planter made of polypropylene (specific gravity = approximately 0.9) is too light and gives an inexpensive impression, and its display stability is low.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and is intended to make the cultivation floor of the box-shaped main body horizontal or inclined at a desired angle even if the installation place is inclined. The aim is to provide a planter that can do it.

[0007] In each of the above structures, the movable leg is formed by using a recycled polyethylene terephthalate material as a forming raw material.

[0008]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a planter according to an embodiment of the present invention, and FIG. 2 is a side and side sectional view when two planters are stacked. In each of the drawings, the planter 1 according to this embodiment is mostly constituted by a rectangular box-shaped main body 3 having an upper surface opening 2. At four corners of the floor bottom 4 of the box-shaped main body 3, main body legs 5, 5, 5, and 5 are formed to protrude downward, respectively.

A step 13 is provided between the outer surface of the box-shaped main body 3 and each of the main body legs 5. An inward projection 12 is provided on the inner peripheral surface of the box-shaped main body 3. In this case, when another planter 1 is inserted from the opening edge 14 of the box-shaped main body 3 of one planter 1 and stacked, the inward projection 1 of the certain planter 1
The step portion 13 of another planter 1 is placed and supported on the top 2 (see FIG. 2). Reference numeral 11 denotes a small projection protruding from the lower surface of each main body leg 5.

Each of the main body legs 5 has a through hole 6 vertically penetrating the respective bottom (an example of the bottom in the present invention).
Are drilled. On the inner peripheral surface of each through hole 6, a first screw portion 7 which is a female screw is provided. A movable leg 10 having a second threaded portion 8 (here, a male screw) of a male screw on the outer peripheral surface is attached to these through holes 6. The second screw portion 8 is adapted to screw with the first screw portion 7 of the main body leg portion 5, whereby the movable leg 10 moves up and down with respect to the box-shaped main body 3.

In this embodiment, both the box-shaped main body 3 and the movable leg 10 are made of polyethylene terephthalate (PE).
T). However, the materials of the box-shaped main body and the movable legs according to the first aspect of the present invention are not limited to PET. Polyethylene terephthalate is a kind of saturated polyester, has a melting point of about 280 ° C., and has a lower limit operating temperature of −3.
Resistant to low temperatures of 0 ° C or less. In addition, the molded article is known to have physical properties such as a surface having a smooth surface, a glossy appearance, a low water absorption and a low coefficient of thermal expansion, a high dimensional stability, and a high thermal barrier property.

As shown in FIG. 3, the recycled polyethylene terephthalate constituting the box-shaped main body 3 and the movable leg 10 is obtained from the recovered PET bottle 9 and the like. An example of producing such a recycled polyethylene terephthalate material will be described below. First, the PET bottle 9 collected from the city is crushed by a crusher to form flakes having a diameter of about 8 mm. The obtained flakes are washed with hot water of about 80 ° C. to further remove foreign substances such as metals and dust. By storing the cleaned flakes in a drying drum and drying them with hot air at about 150 ° C., a recycled polyethylene terephthalate material is obtained. The box-shaped main body 3 and the movable leg 10 can be obtained by heating the recycled polyethylene terephthalate material obtained as described above as a molding raw material and molding it by, for example, an injection molding machine.

The PET bottles on the market are:
Most are colorless and transparent, and those colored green. Therefore, if only the colorless and transparent PET bottle 9 is selected and used as a raw material, a substantially colorless and transparent box-shaped main body 3 and movable legs 10 can be obtained. On the other hand, green colored PET bottle 9
Is used alone or mixed with a transparent PET bottle 9 to form a raw material, whereby a green box-shaped main body 3 and a movable leg 10 can be obtained. Of course, it is also possible to obtain a box-shaped main body 3 and a movable leg 10 of a desired color by adding a coloring material of another color.

In the planter 1 having the above-described structure, as shown in FIG. 4, humus and the like are put in the box-shaped main body 3 to form a cultivation floor 15, on which horticultural plants 16 are planted. The planter 1 in which the horticultural plants 16 are planted in this way may be installed on a solid inclined plane E inclined at an angle θ from the horizontal plane to the right as viewed in the drawing, for example, as shown in FIG. When the planter 1 is placed on the inclined surface E as it is, the upper surface of the cultivation bed 15 is inclined as the inclined surface E.

Then, when the user turns the movable leg 10 by hand, the second screw portion 8 advances with respect to the first screw portion 7,
The movable leg 10 moves up and down from the bottom of the main body leg 5 in the vertical direction (the direction of arrow M in FIG. 2). In this case, for example, the tilt of the planter 1 is adjusted and the upper surface of the cultivation floor 15 is leveled by turning the movable leg 10 on the left side in the drawing and feeding it downward.

On the other hand, when the movable leg 10 is placed on the inclined surface E1 (two-dot chain line) rising leftward in the drawing opposite to the inclined surface E, for example, the movable leg 10 on the left side of the drawing is removed and the movable leg 10 on the right side is turned by hand. By increasing the extension length of the movable leg 10, the inclination of the planter 1 is adjusted.

As described above, in the planter 1 of the present embodiment, since the movable leg 10 moves up and down only by turning the movable leg 10 by hand, even if the installation place is inclined,
Anyone can easily adjust the inclination of the box-shaped main body 3. Thereby, the upper surface of the cultivation floor 15 is made horizontal or inclined at a desired angle.

Since the specific gravity of polyethylene terephthalate is as heavy as about 1.4, the planter 1 of this embodiment, which is made of recycled polyethylene terephthalate, has a high weight and gloss and is dignified, and may be stacked when the product is displayed. Due to high stability, it is hard to collapse. Moreover, since polyethylene terephthalate contains carbon, hydrogen, and oxygen as constituent elements in the same manner as wood and paper, no toxic gas or harmful substance is generated even if incinerated. Therefore, after use, the planters may be incinerated or collected.

In the above-described embodiment, the first screw portion 7 on the box-shaped main body 3 is formed by a female screw, and the second screw portion 8 on the movable leg 10 is formed by a male screw. It is not limited to the configuration. For example, as shown in FIG. 6, a bolt 17 is suspended from the lower surface of the main body leg 5, and a male screw of the bolt 17 is used as a first screw portion 7 a. 10a may be provided. The movable leg 10a has a second screw portion 8a which is a female screw.
Is provided. Also in this case, the second screw portion 8a is
The movable leg 1 is screwed with the screw portion 7a.
By turning Oa in the direction of arrow R, the movable leg 10a moves up and down (direction of arrow M) with respect to the main body leg 5.

In the above embodiment, the first screw portions are disposed at the four corners of the bottom of the main body. However, the positions of the first screw portions in the planter of the present invention are not limited to the four corners of the bottom of the main body.
Further, the number of the first screw portions provided is not limited to four. The shape of the box-shaped main body is not limited to the above-described rectangle, but may be a spherical shape, an elliptical spherical shape, or any other desired shape.

[0021]

As described in detail above, according to the planter of the present invention, the movable leg is formed by screwing the first screw of the bottom of the box-shaped main body and the second screw of the movable leg. The movable leg moves up and down from the bottom by simply turning the movable leg by hand. Therefore, when installed in an inclined place, anyone can easily adjust the inclination of the box-shaped main body, and the cultivation floor in the box-shaped main body can be leveled or tilted at a desired angle. Thereby, it is possible to prevent the planted flowers and the like from being tilted to impair the appearance, and to prevent the excavated soil at the time of watering from spilling and exposing the roots.

When a box-shaped main body is formed by using a recycled polyethylene terephthalate material as a forming raw material, a PET bottle or the like generally used as a beverage container can be collected and recycled. In addition, since the box-shaped main body in the present invention occupies most of the planter, it greatly contributes to recycling. Also, since polyethylene terephthalate has a high specific gravity, it has a heavy feeling,
Stability is also high when planters are stacked during product display.

The case where the movable leg is made of recycled polyethylene terephthalate is the same as the case of the box-shaped main body described above. In particular, when both the box-shaped main body and the movable leg are made of recycled polyethylene terephthalate, the entire planter can be recycled and used, which is more preferable.
