Description of the Related Art Heretofore, as a packaging container for packaging or holding food or drink such as instant noodles or lunches or daily necessities, those mainly made of a resin such as polyethylene have been widely used. However, such containers are discarded in large quantities after use, but may emit toxic gases when incinerated. There is a problem. Also,
Bamboo is one of the natural products that has few problems even if it is discarded or incinerated, and has a short time until it can be harvested once it has been harvested from its production area. And there is a packaging container using bamboo for a long time. In this device, the container is formed by weaving a bamboo that is obtained by cutting bamboo into a slender shape, or the bamboo is sliced and the shape of the bamboo itself is almost left as it is. However, with such a configuration, it is necessary to manufacture the packaging container almost by hand, and it is extremely difficult to mass-produce the packaging container. Further, the shape of the completed packaging container is limited. Therefore, a conventional container using bamboo cannot be used as a substitute for the above-mentioned resin-based packaging container.

【０００８】図１（ａ）に示すように、竹１を用意す
る。この竹１としては、肉厚Ｗが１０ｃｍ以上のものを
用いる。例えば、中国産の孟宗竹が好適である。なぜな
ら、この孟宗竹は、肉厚が２０ｃｍ程度と厚いので、後
述するスライスされた板材をまとめて取出すことができ
るためである。As shown in FIG. 1A, a bamboo 1 is prepared. The bamboo 1 used has a thickness W of 10 cm or more. For example, Chinese Moso bamboo is suitable. This is because this Moso bamboo has a thickness of about 20 cm, so that sliced plate materials described later can be collectively taken out.
【０００９】次に、図１（ｂ）に示すように、竹１をそ
の軸方向と直角に所定長さＬ（通常２ｍ程度）毎に切断
して、切断された母材２、３とする。そして、図１
（ｃ）に示すように、防虫剤を含む溶液を溜めた容器４
に、母材２、３を入れ、防虫剤を母材２、３に含浸させ
るとともに煮沸する。これにより、母材２、３は虫が付
きにくくなり、また軟化して加工しやすくなる。そし
て、容器４から母材２、３を取り出して、乾燥させる。Next, as shown in FIG. 1 (b), the bamboo 1 is cut at a predetermined length L (usually about 2 m) at right angles to the axial direction to obtain cut base materials 2, 3. . And FIG.
As shown in (c), a container 4 containing a solution containing the insect repellent
Then, the base materials 2 and 3 are put, and the insect repellent is impregnated into the base materials 2 and 3 and boiled. As a result, the base materials 2 and 3 are less likely to stick to insects and are softened and easily processed. Then, the base materials 2 and 3 are taken out of the container 4 and dried.
【０００８】次に、図１（ｄ）に示すように、母材２が

あるが、皮は、機械的性質がその他の部分と大きく異な
るので、スライスした竹６として使用しない。Next, as shown in FIG. 1D, when the base material 2 is dried, the sliced bamboo 6 is taken out from the base material 2. That is, the slice is performed by applying the cutter 5 while rotating the base material 2 in the arrow n1 direction. In addition, although there is a skin on the outer peripheral portion of the base material 2, the skin is not used as the sliced bamboo 6 because its mechanical properties are greatly different from other portions.
【００１０】そして、図１（ｅ）に示しているように、
スライスした竹６を一定の矩形にカッタＤでカットし、
一定形状を有する薄板７、８とする。なお、薄板７、８

Cut the sliced bamboo 6 into a fixed rectangle with cutter D,
The thin plates 7 and 8 have a fixed shape. In addition, the thin plates 7 and 8
Has a fiber orientation.
【００１１】次に、薄板７、８を再度乾燥させ（図１
（ｆ））、これを炭化処理する（図１（ｇ））。炭化処

制される。しかし、包装用容器の用途によっては、炭化
処理は省略しても差し支えない。Next, the thin plates 7 and 8 are dried again (FIG. 1).
(F)) and carbonized (FIG. 1 (g)). When carbonized, the insect / mold resistance is improved, and the habit of bamboo is forced. However, depending on the use of the packaging container, the carbonization treatment may be omitted.
【００１２】次に、図２（ａ）に示すように、少なくと
も一方の薄板８に、接着剤９を塗布し薄板７、８を貼り
合わせて合板１０とする。ここで上述したように、薄板

くしたいときは、薄板７、８の繊維の方向が互いに直交
するようにするか、または２枚以上貼り合わせるとよ
い。また、合板１０を後で複雑な形状にするときなど、
加工性を重視すべきときは、合板１０を構成せず、１枚
の薄板のみにしてもよい。Next, as shown in FIG. 2A, an adhesive 9 is applied to at least one of the thin plates 8 and the thin plates 7 and 8 are bonded to form a plywood 10. As described above, although the thin plates 7 and 8 have the directionality of the fibers, when the strength of the plywood 10 is desired to be increased, the directions of the fibers of the thin plates 7 and 8 are set to be orthogonal to each other or two sheets are used. Above, it is good to stick. Also, when the plywood 10 is to be made into a complicated shape later,
When emphasis is placed on workability, the plywood 10 may be omitted and only one thin plate may be used.
【００１３】さらに、２枚の薄板７、８の間に、樹脂か

板１０を補強するためのものであり、人畜無害のものを
使用する。なお、本形態では、２枚の薄板７、８を積層
したが、必要に応じてより多くの板材を積層してもよ
い。Further, a thin protective layer made of resin may be interposed between the two thin plates 7 and 8. This protective layer is for reinforcing the plywood 10, and is harmless for humans and animals. In the present embodiment, two thin plates 7 and 8 are stacked, but more plate materials may be stacked as needed.
【００１４】次に、図２（ｂ）に示すように、研磨装置
１１により、合板１０の表面を研磨する。これにより、
合板１０の毛羽立ちなどが取り除かれ、また合板１０の
平面性も向上する。Next, as shown in FIG. 2B, the surface of the plywood 10 is polished by the polishing device 11. This allows
Fluff of the plywood 10 is removed, and the flatness of the plywood 10 is also improved.
【００１５】次に、合板１０を、目的の包装用容器にあ

ないので、金型に湯道を形成しておく必要はない。ま
た、合板１０の加工性は良好であり、金型の形状次第に
よって種々の形状の包装用容器とすることができる。Next, the plywood 10 is set in a mold formed in advance in accordance with the intended packaging container, and the plywood 10 is pressed with the mold to form a container 12. Here, this mold may be substantially the same as that for a conventional packaging container mainly made of resin. However, in order to manufacture the packaging container of the present embodiment, it is not necessary to inject the resin into the mold, so that it is not necessary to form a runner in the mold. Further, the workability of the plywood 10 is good, and various shapes of packaging containers can be obtained depending on the shape of the mold.
【００１６】さて、金型で容器１２を得ると、図２のよ
うな包装用容器を製造するときには、上縁部１３の形状
が不定となって、通常この上縁部１３にバリがある。し
たがって、図１（ｄ）に示すように、上縁部１３のバリ
を取り除いて成形する。なお、金型のプレスを行う際
に、同時にバリをカットしても良い。When the container 12 is obtained by a mold, the shape of the upper edge portion 13 becomes indeterminate when a packaging container as shown in FIG. 2 is manufactured, and the upper edge portion 13 usually has burrs. Therefore, as shown in FIG. 1D, the burrs of the upper edge portion 13 are removed and the molding is performed. The burrs may be cut at the same time when the mold is pressed.
【００１７】次に、図１（ｅ）に示すように、包装用容

たら、完成品となる（図１（ｆ））。Next, as shown in FIG. 1E, depending on the use of the packaging container 12, such as the outer surface of the packaging container 12,
A transparent or translucent resin 14 is coated.
When the coating is performed, the packaging container 12 is polished,
Not only does the bamboo fiber pattern appear clearly and the appearance improves, but the coating can also provide waterproofness. This makes it possible to pour a liquid such as boiling water into the packaging container 12, which is suitable for use in packaging containers for instant foods. Here, in the packaging container according to the present embodiment, since a pattern of bamboo fiber, which is a natural thing, appears, unlike a conventional packaging container mainly made of resin, the packaging container has a classy appearance rather than a tasteless and dry appearance. Appearance. Then, when the coated resin 14 is dried and fixed, a finished product is obtained (FIG. 1F).
