[0001]
BACKGROUND OF THE INVENTION
The present invention, recycled plastic bottles such as PET bottles as the material relates to bedding pot unit type can be used as a flower bed for partition by placing successively sequential.
[0002]
[Background Art and Problems to be Solved by the Invention]
In recent years, especially from about 10 to 15 years ago, due to its convenience, PET bottles or similar plastic bottles (simply referred to as “PET bottles” in this specification) have begun to be frequently used as containers for various liquids. It was.
[0003]
Certainly, these PET bottles can be manufactured inexpensively by blow molding, etc., and since they are lightweight and do not break like glass bottles, they are convenient in terms of portability and storage. Used as a storage container for beverages such as juices that have been sold, and as a storage container for hair washing liquids (shampoos, rinses, etc.) as well as ingredients used for cooking such as soy sauce or sauces. began.
[0004]
However, these PET bottles are not intended to be reused, and have been intended to be disposable from the beginning, so when the contents are exhausted, the garbage collection system of each local government as daily garbage, Collected at the garbage disposal site.
[0005]
The simplest treatment for these plastic bottles is incineration at the incineration site and injection into the landfill, but in the former, the combustion gas becomes harmful and diffuses over a considerable range, The latter does not corrode / decompose even when thrown into a landfill and contains water and moisture, resulting in an unsanitary state, and neither treatment is appropriate as a treatment for a PET bottle.
[0006]
In particular, in recent years, prevention of environmental pollution on a global scale and resource saving have been screamed, and as part of this, many countries including Japan are struggling with the ever-increasing amount of PET bottle processing. Currently.
[0007]
By the way, in the past, concrete flower bed pots have been placed in front of public objects such as station squares or police boxes (alternations), and the pots are planted with four seasons and the surrounding atmosphere. Is softening. In some cases, the flower bed pots are arranged continuously or at a predetermined interval, and are used for the purpose of partitioning the use space, such as a section of a roadway and a sidewalk or a sidewalk and a bicycle parking lot (bicycle storage). ing.
[0008]
The pot for the flower bed is aesthetically treated for its use. For example, in the case where the overall shape is a tal shape or a rectangular parallelepiped shape whose upper side is open, a process such as forming irregularities on the surface or bordering the contour portion is performed.
[0009]
However, these aesthetic treatments are exclusively inexpensive because the flower bed pots described above are used in large quantities and require durability against impact and corrosion. It is made of concrete having a high durability, and the aesthetic treatment as described above is the limit for the aesthetic treatment.
[0010]
The present invention has been made in view of the two current status as described above, and aims to provide a unitary bedding pot capable and high aesthetic treatment that may significantly to contribute to the recycling of PET bottles is to perform To do.
[0011]
[Means for Solving the Problems]
The pot for a unit type flower bed according to the present invention which is intended to solve the above technical problem is to cover the base which is open at the top and is planted with plants such as plants, flowers and the like, and the front of the base. A pot for a unit-type flower bed with a lid to be arranged,
The volume of this pot is about 0.001 to 1 m²,
The base body is formed of a material containing about 1 to 35% by weight of recycled plastic from PET bottles as an aggregate, forming a square or a rectangle in front view and plan view, and the side on the front side in the side view being the upper end In the shape of a trapezoid that retreats and protrudes at the lower end, and slits for inserting and locking the lid body are provided symmetrically on the inner surface side of both side walls,
The lid body is formed of a material containing about 9 to 30% by weight of a PET bottle processed into a strip shape, and is inserted into slits formed on the inner surface sides of the both side walls of the base at both ends. It is formed in a possible thickness, and a pattern is formed on the front surface of the lid by bending, refracting or overlapping a linear object, and has an opening opened toward the front so as to plant the plant. With
A reinforcing U-shaped reinforcing bar is disposed inside the base body, and a reinforcing metal net or a plastic reinforcing mesh is disposed on the lid .
[0012]
Thus, according to the unit pots for expression flower beds having such a structure, a PET bottle, without consuming much energy, as the raw material of the lid, also as the aggregate of the substrate, large quantities processed ( Consumption). In addition, no harmful substances are emitted during this process. Further, if a reinforcing U-shaped reinforcing bar is disposed inside the base body, and a reinforcing metal net or plastic reinforcing mesh is disposed on the lid, structurally, Also, the structure is stronger against external force such as impact.
[0013]
In addition, since the lid for the unit type flower bed is made of the above-described components, it has a very high-class feeling, and various designs can be easily formed. In addition, since the lid body has a certain degree of elasticity and low hardness, even if a person hits it, there is no injury and the pot is not broken.
[0014]
The unit-type flower bed pot according to the present invention is manufactured by the following manufacturing method. That is, a metal crown or the like is removed from the collected ped bottles, and the PET bottles are crushed and cut into a 2-6 mm wide strip shape. And the raw material in the form of strips is "3-7" by weight, either polyethylene or polypropylene is "3-7" by weight, vinyl acetate is "3-7", and elastomer is the same. "1-4", hot melt adhesive is also "0.5-2", calcium carbonate is also "1.5-3.5", talc is also "0.2-0.7", acrylic acid In the heating and kneading apparatus at the same ratio of “0.003 to 0.008”, the woody material such as wood powder or coco pate as “1-2”, and the blowing agent as “0.10-0.25”. Knead by heating. Next, a linear body is extruded from the nozzle of the extruder connected to the heating and kneading apparatus, and a desired planar lid is formed below the linear body.
[0015]
On the other hand, apart from the above process, the linear body extruded from the extruder is solidified, and the solidified body is pulverized to an appropriate size by a pulverizer. Next, the pulverized product is used as one of the aggregates, and the ratio is “6.0 to 8.5” by weight, sand is “9 to 11”, and cement is “6.0 to 8.5”. And then knead to a sol state by adding water. The kneaded product is poured into a mold that opens so that the flat lid on the front can be locked and a plant can be planted on the upper side, and is solidified to form a substrate in a predetermined shape.
[0016]
Finally, it is characterized by comprising a series of steps of removing the mold, taking out the base, and locking a separately formed lid on the base.
[0017]
DETAILED DESCRIPTION OF THE INVENTION

[0019]
【Example】
Hereinafter, a unit type flower bed pot according to an embodiment of the present invention will be described in detail with reference to the drawings.
[0020]
FIG. 1 is a perspective view showing the overall structure of a base of a unit-type flower bed pot according to an embodiment of the present invention, and FIG. 2 is a perspective view showing the structure of the lid body as seen obliquely from the front.
[0021]
As shown in these drawings, the unit-type flower bed pot is composed of a concrete base A and a plastic lid B disposed in the opening 1 portion on the front surface of the base A.
[0022]
The lid B has a width b equal to the inner dimension w between the slits 2 formed slightly inward from the front surface of the base A, and more precisely, the width b is slightly smaller than the inner dimension w. Has been. Further, the thickness d of the lid B is equal to the slit width r of the slit 2, and precisely, the thickness d is slightly smaller than the slit width r.
[0023]
The lid B has a pattern formed by bending or refraction or superimposing a linear body on the front surface, and an opening 6 opened toward the front surface is formed.
[0024]
The base A has a volume of about 0.001 to 1 cubic meters, and in this embodiment, the width is 50 cm, the height is 60 cm, the average depth (height in the middle) is 50 cm, and the volume is about 0.15 cubic meters. belongs to. In addition, the rectangular shape is a slightly long rectangle in front view and the upper end is square in plan view and has a long side with a long side as it goes to the lower end. Further, as shown in FIG. 5, the side 3 on the front side in a side view has a trapezoidal shape with the upper end retreating at the upper end and protruding at the lower end, and a lid is inserted on the inner surface side of the both side walls 4 as shown in FIG. The slit 2 for locking is provided in the inner side along the side 3 in a symmetrical manner. In this embodiment, U-shaped reinforcing bars 5 having a U-shape in plan view are inserted in three places at the top and bottom.
[0025]
Next, the manufacturing method of the lid B will be described. First, the collected plastic bottle is processed by the plastic bottle processing apparatus. In this PET bottle processing apparatus, rubber crushing rollers are arranged opposite to each other, and below that, a PET bottle crushed into a substantially plate shape by the roller is about 5 mm wide and about 1 to 2 cm wide. A cutting mechanism for cutting into strip pieces having a length is provided. And in processing, a PET bottle is thrown into the hopper of this PET bottle processing apparatus, and is processed into the strip-shaped thing about 5 mm in width and about 1-2 cm in length.
[0026]
Next, this processed plastic bottle piece is "3-7" by weight, either polyethylene or polypropylene is "3-7" by weight, vinyl acetate is also "3-7", elastomer "1-4", hot melt adhesive "0.5-2", calcium carbonate "1.5-3.5", talc (talc) "0.2-0. 7 ", acrylic acid is also" 0.003 to 0.008 ", wood powder or cocopyrt is similar to" 1-2 ", foaming agent is also" 0.10 to 0.25 ", It is put into a hopper of a heat kneader and heated and kneaded into a sol form. That is, stirring is performed so that each raw material is evenly distributed while being heated and melted. As a preferred embodiment, the plastic bottle is "5" by weight, either polyethylene or polypropylene is "5" by weight, vinyl acetate is "5", elastomer is "3", hot melt The mold adhesive is also "0.7 to 0.8", calcium carbonate is also "2.5", talc is "0.5", acrylic acid is "0.004", wood powder or coco peat etc. “1.5” for wood, “0.15” for foaming agent, “2.5” for “shirasu (volcanic soil)”, and preferably a small amount of release agent (in parts by weight). “About 0.005 to 0.01”) and a small amount of coffee, tea, herb, laurel, buckwheat husk or chemically synthesized fragrance (for example, in the case of coffee, “0.01 by weight” ) Degree) It was put into the hopper of the apparatus, heated kneaded sol. Moreover, instead of a fragrance | flavor, you may use wood flour, such as an oak and an oak, as said wooden material.
[0027]
Next, from the nozzle of the extruder continuously disposed in the heating and kneading apparatus, the above heated and kneaded sol form is dropped downward by gravity.
[0028]
Below, a metal mesh with a roughness of about 1 cm is placed on a mold such as a wooden mold or a mold, and the fallen sol-like shape is a pattern suitable for the mesh shape by hand, For example, the mold is filled while forming a pattern as shown in FIG. 2 or FIG.
[0029]
In this case, the mold is used in order to obtain a thickness and a planar shape that can be just inserted into the slit 2 of the base A. The upper surface of the mold is open so that the surface of the pattern drawn by bending, refracting, or superimposing the linear body on the surface does not become a surface with no irregularities (a surface that does not change in design). Because.
[0030]
Further, when the lid B is formed as described above, the openings 6 are formed at appropriate intervals.
[0031]
When forming the lid B or continuously between the molding, the sol-like linear body is discharged from the nozzle of the extruder, and when these do not contribute to the molding, Put it in the water.
[0032]
And what was thrown in the above is a bent line or rounded dumpling, but the maximum diameter is 3-8 mm in the form as shown in FIG. Crush (pulverize) into small pieces (small grains).
[0033]
That is, when the base A is manufactured, the pulverized small pieces (small grains) are used as one of the aggregates of concrete. In this case, as the aggregate, the larger the “variation” in the size and shape of the small pieces, the better the performance as the aggregate.
[0034]
The base A is manufactured by pouring sol-like concrete into a metal mold in the same manner as a cement product such as a normal block as follows. Specifically, the crushed material is one of the aggregates, and the parts by weight are “6.0 to 8.5”, the sand is “9 to 11”, and the sentiment is “6.0 to 8.5”. Mix in proportion, add water to this and knead to sol state. As a preferred embodiment, the ratio of “7.0 to 7.5” by weight, sand is also “10”, and sentiment is also “7.0 to 7.5” with the pulverized one as an aggregate. In this case, the mixture is kneaded in a sol form by adding water, and the form is opened so that the front can be engaged with the flat lid B and the plant is planted upward. Pour into and harden.
[0035]
This formwork may be removed in about 2 to 3 days, as in the case of ordinary concrete. Thus, if the lid B is inserted into the slit 2 of the molded base A, a unit-type flower bed pot is completed. FIG. 5 shows a longitudinal section at the center of the pot. Moreover, when a flower and a tree are planted there, it will become as shown in FIG.
[0036]
In actual use, a unit such as a well-drained mat is laid on the bottom of the unit-type flower bed pot as a bottom material 10, and soil suitable for plant growth is placed on the mat, and desired. Plant flowers and trees. In this case, if the crushed material used as the aggregate of the concrete is mixed in the soil of the pot, the water retention will be improved and the drainage will be improved, and fertilizer etc. will enter the gap between the crushed materials. In addition, it prevents soil from solidifying (improves air permeability), making it suitable for plant growth. That is, since the pulverized material is porous and does not solidify with the soil, the above-described effects can be obtained. In this case, the grain size is about 3 to 8 mm in the case of “Orchid”, and in the case of other flowers, it is desirable to use a powder pulverized to 3 mm or less. Moreover, as a mixing ratio, the above-mentioned pulverized product is used by mixing 5 parts by weight, the same 5 for the cocopyant, the same 5 for the mass, and the same 3 for the sanitary soil.
[0037]
Then, as shown in FIG. 3, the unit-type flower bed pots can be used as a partition of a space if they are arranged in a line, and if they are placed in front of a wall or the like, they have an excellent effect as a decoration for a space. In FIG. 3, the pattern of the lid B to be illustrated is omitted from the left end and two adjacent flower bed pots. Moreover, in this figure, a mode that the following connection member C is arrange | positioned in the connection part of the right end and the flower bed pot adjacent to it is shown.
[0038]
By the way, as shown in FIG. 4, if the connecting member C for connecting the flower bed pots is formed by a linear body from the extruder, as in the case of the lid B, the cement of the adjacent base A Each end face is hidden behind it, and the decoration effect is further enhanced.
[0039]
Moreover, each said mixing ratio can be implemented in the range mentioned above. Here, the temperature in the heating and kneading apparatus is about 120 to 200 ° C., and the temperature in the extruder is preferably about this level. In the case of this example, the nozzle diameter of the extruder is about 3 to 8 mm, but this varies depending on the capacity (performance) of the kneading apparatus and the extruder.
[0040]
Various foaming agents mentioned above can be considered. In this example, azodicarbonamide (ADCA) or benzenesulfonyl hydrazide (OBSH) is used. If wood powder is used, use 70-180 mesh. In addition, the above-mentioned “cocopyt” is produced as a residue when a rope is produced with a coconut skin, and the size of each grain is equivalent to the above wood powder or slightly finer (180 mesh). That's it. Further, in the above examples, as the elastomer, “Nippon Synthetic Rubber Co., Ltd., trade name“ JSR NV70 ”” and as the hot melt adhesive, “Konishi Co., Ltd., trade name“ NH153 ””, As the mold release agent, “trade name“ E ”” of Hoechst Japan Co., Ltd. is used.
[0041]
Thus, in the unit type flower bed pot according to the present embodiment, about 150 to 400 bottles can be reused as one unit type flower bed pot. In the southern part of Kyushu, it is possible to push out from the nozzle of the extruder at a higher speed by using “Shirasu”, which is the main cause of debris flow, and to increase the strength. In addition, when using "shirasu", the said mold release agent is added about the weight part mentioned above.
[0042]
And, since the unit type flower bed pot manufactured in this way is configured in a unit type and can be appropriately continued in length, it can be used as a boundary between the sidewalk and the roadway or in the center of the sidewalk. It can be arranged freely for planting flowers.
[0043]
【The invention's effect】
Therefore, according to the unit type flower bed pot manufacturing method and unit type flower bed pot according to the present invention, it is possible to effectively use a large amount of PET bottles that have been difficult to dispose of in the past, and the completed pot itself. Is very decorative, and therefore can be used effectively as a space decoration and space partitioning means by planting flowers, trees and the like. Furthermore, since the lid made using the above PET bottles is made of a porous material, it has the contradictory performance of water retention and drainage, and can maintain and manage plants such as flowers and trees. It will be easy. Furthermore, since this lid body has high impact resistance and is not hard like iron or concrete, it does not damage even if people come into contact with it, so it is also suitable as a partition means for roadways and sidewalks. .
