等があった。2. Description of the Related Art Conventionally, a molded article, for example, a cushioning material used for fixing the article inside a box for packing the article when the article is distributed, and a packing box for transporting fish at a low temperature. In addition, food containers and trays for placing food in small portions at retail stores, pots for planting plants, etc., are low in manufacturing cost, easy to process, easy to handle, and disposable. In addition, plastic materials, styrene materials (including styrene foam; the same applies hereinafter), water-resistant paper, and unglazed or ceramics such as pottery have been used because they can be incinerated. Such molded articles include, for example, lunch containers and cups using plastic materials, and styrene foam products include fresh food trays, side dish trays, instant noodle cups, and the like. In addition, there were unglazed flower pots, pottery, etc. in the baked goods.

また、素焼きの花鉢等は、そのままでは分解されること
はなかった。[0003] However, such materials used in the prior art have environmental problems in disposal. With plastic materials, incineration increases the cost of incineration and sometimes produces toxic chemicals such as dioxin. In the case of styrene and plastic materials, if they are not incinerated, they will not be decomposed by microorganisms.
There was a problem of destroying the environment. Furthermore, paper that has been subjected to water-resistant processing is not easily decomposed by microorganisms,
Due to the structure of paper, the strength is not sufficient and there is a problem that there is a restriction on the use of molded articles such as food containers.
Unglazed flower pots and the like were not decomposed as they were.
【０００４】このため、廃棄処理に際して環境上の問題
を改善すべく、食品容器やトレイについては、膨張加工
したコーンを所望の形状及びサイズにした基体とこの基
体の表面に設けられると共にこんにゃくと穀類の混合体
からなる接着部材とよりなる容器についての技術が考え
られた（特許第２５６８９６８号）。[0004] Therefore, in order to improve environmental problems in the disposal process, food containers and trays are provided with a base in which an expanded cone is formed in a desired shape and size, and a base on the surface of the base and konjac and cereals. (Japanese Patent No. 2,568,968) was conceived for a container comprising an adhesive member made of a mixture of the above.
【０００５】この技術による容器は、食品となる素材を
用いて構成されている。このため、食品の収納に用いた
場合には、使用後にはそのまま食べることが可能であ
り、廃棄物となるゴミが生じない。また、使用後に焼却
することもできる。さらに、回収されずに放置された場
合でも最終的には生分解されて土になりゴミのまま残る
ことがない。[0005] A container according to this technique is formed using a material that becomes a food. Therefore, when used for storing food, it can be eaten as it is after use, and no garbage as waste is generated. It can also be incinerated after use. In addition, even if it is left uncollected, it is not biodegraded and eventually becomes soil and remains as garbage.
【０００６】また、この技術では基体はコーンを加熱
し、これを膨張させたものを素材として用いているた
め、容器の形状及びサイズに合わせた型に入れ、加圧成
形することにより任意の形状に加工できる。Further, in this technique, since the base is obtained by heating a cone and expanding the cone, the base is placed in a mold corresponding to the shape and size of the container, and is formed into an arbitrary shape by pressure molding. Can be processed.
【０００７】さらに、基体表面全体を接着部材により膜
状または層状に覆っているため、容器内にジュース等の
水ものまたは水気を含んだ食品などを入れても外部に漏
れないようにできる。Further, since the entire surface of the base is covered in a film or layer with an adhesive member, even if water such as juice or food containing water is put in the container, it can be prevented from leaking to the outside.
【０００８】したがって、以上のことから、食品容器や
トレイが使用済みになって廃棄されても生分解されるの
で環境破壊等を招くことがなく、任意の形状が成形でき
るので使い勝手に優れるという効果を奏するというもの
である。[0008] Therefore, from the above, the food container or tray is biodegraded even when it is used and discarded, so that it does not cause environmental destruction and the like. Is played.
【０００９】一方、成形材については、合成樹脂の使用

えば、ポリオレフィン樹脂と混合して用いた成形材につ
いては、特開平１１−１４８０１７がある。On the other hand, the molding material is obtained by mixing bamboo powder with a polyolefin resin and / or a biodegradable resin at a predetermined mixing ratio from the viewpoint of reducing the amount of synthetic resin used. Japanese Patent Application Laid-Open No. H11-148017 discloses a technique constituted by such a method, for example, a molding material used by mixing with a polyolefin resin.
【００１０】この技術による成形材は、竹の粉末が棒状
となりその繊維が強靭であることから、成形材の強度を
強くできる。[0010] The molding material according to this technique can increase the strength of the molding material since the bamboo powder becomes rod-like and the fibers are tough.
【００１１】また、竹の粉末が細長い繊維状であること
から、成形材を燃焼炉で燃焼させると溶けて液体状にな
った樹脂が竹の粉末によりつなぎとめられるので、燃焼
滴下物が少なくなって炉床をよござず、また、合成樹脂
分が少ないので、焼却炉の熱効率が改善される。Further, since the bamboo powder is in the form of a long and thin fiber, when the molding material is burned in a combustion furnace, the melted and liquid resin is connected by the bamboo powder. The heat efficiency of the incinerator is improved because the hearth is not touched and the synthetic resin content is small.
【００１２】さらに、竹には抗菌作用があることから、
別途抗菌剤を混ぜなくても、抗菌作用を成形材にもたせ
ることができる。Furthermore, since bamboo has an antibacterial effect,
The antibacterial action can be imparted to the molding material without separately adding an antibacterial agent.
【００１３】加えて、竹は、従来、廃棄されていたもの
であるので、廃棄物の再利用ができ、焼却しても合成樹
脂分が少ないので、この限度において自然環境の汚染が
防止できる。In addition, since bamboo has been conventionally discarded, the waste can be reused. Even if it is incinerated, the amount of synthetic resin is small, so that pollution of the natural environment can be prevented at this limit.
【００１４】他方、植物用の鉢については、素焼きのも
のや陶器製のものがあるが、これらは植物の運搬には都
合がよく、そのまま任意の個所に設置できるという利点
がある。On the other hand, pots for plants include those made of unglazed and pottery, which are convenient for transporting the plants and have the advantage that they can be installed at any location as they are.

しての使用が困難になるものであった。However, in the prior art disclosed in Japanese Patent No. 2,568,968, a desired shape and the like are formed by a cone, and a mixture of konjac and cereals is made water-resistant. A plurality of materials are required, the manufacturing process is complicated, and the manufacturing cost is high. In addition, since it is premised that corn can be eaten, it is necessary to use the real part of the corn, and the waste material other than the fruit cannot be effectively used, and the waste material cannot be effectively used. . For this reason, the manufacturing cost must be high. Further, since the corn was used as a base, the mechanical strength of the formed food container was low. Furthermore, when boiling water is poured, the water resistance is extremely reduced due to heat, which makes it practically difficult to use as a container.

れている。Further, of the above prior arts, Japanese Patent Application Laid-Open
Since the technology of 148017 is to mix bamboo powder with synthetic resin, in this regard, for the part requiring synthetic resin, the strength of the molded product cannot be further increased,
In addition, when incinerated, the hearth of the incinerator was contaminated, the improvement of thermal efficiency was limited, and the contamination of the natural environment could not be prevented because it was not decomposed by microorganisms. With the recent enactment and enforcement of the Containers and Packaging Recycling Law, for molded products in general, there is a strong demand for alternatives to materials that cause environmental problems during disposal, such as conventional plastics and Styrofoam.

え替える際には鉢を回収する必要があった。たとえば、
道路の分離帯に置かれた素焼きの鉢に植えられた花など
は、その鉢の回収の手間が必要であった。Further, since unglazed or pottery pots conventionally used for flower pots and the like are not biodegraded, it is necessary to collect pots when newly repotting. For example,
For flowers and the like planted in unglazed pots placed on the road divider, it was necessary to collect the pots.
