題を有している。Such a molded container is used for packing articles in the distribution process from the producer to the consumer, and the number of the used containers is increasing year by year. ing. Since such a molded container is thrown as garbage when it reaches the hand of the consumer, the disposal of the waste is inevitably a problem.
That is, the waste of the synthetic resin molding container as described above does not naturally decompose and remains as a solid, which impairs the aesthetics of the environment and, when burned, has a high burning calorie (for example, 11,100 Kcal / in polypropylene). Kg), the damage to the incinerator is large, and the amount of gas generated during combustion is large,
There is a problem that toxic gas is generated to remarkably pollute the natural environment.

Compared with the conventional synthetic resin material alone, the calories burned can be significantly reduced and the adverse effect on the incineration facility can be mitigated, and the presence of mixed starch can suppress the generation of toxic gas. And, when it is dumped as garbage, it can promptly promote natural degradation by weathering and microorganisms,
It can greatly contribute to the social problem of improving environmental pollution, and a container suitable for disposal as a disposable container can be obtained.

A hinge portion 3 that connects the two portions 1 and 2 to each other in an openable and closable manner is integrally molded from a thin sheet material A by using vacuum or blow molding means. Further, the body 1 is formed with recesses 4 ... Which form a plurality of egg holding spaces aligned when the two parts are closed. In the figure, 5 is a partition strut for the recesses 4, 6 is a partition wall, and 7 is the top of the partition wall.

It is better to be as low as 45%, and 45-60 if you attach importance to weathering when disposing as garbage and decomposition function by microorganisms.
A high blending ratio of high% is good.

ができる。Further, since this starch may be blended as it is, or may be crushed and kneaded into emulsion to be blended with the above synthetic resin, it can be blended immediately as a material for forming a sheet material, and powdered in advance. There is an advantage in that it does not require a process such as chemical conversion and equipment for that, and since the lubricity of starch can be utilized, it is possible to effectively retain the characteristics of synthetic resin with excellent extensibility, and it is possible to use a high ratio. Good extensibility as a sheet for molding can be maintained even when blended with.

When it is discarded as garbage, it has the property that it is rapidly decomposed in the natural environment due to weathering and microorganisms.
Further, according to the experimental value of the inventor, the combustion calorie at the time of combustion was 6,000 Kcal / Kg when polypropylene was mixed with 50% starch (polypropylene was 11,
A low value of 100 Kcal / Kg) was obtained.

ができる利点がある。As is apparent from the above description, the molded container according to the present invention is made of polyethylene, polystyrene,
A thin synthetic resin material such as polyethylene or polyvinyl chloride, which has a high extensibility and is made of a new material that is a mixture of starch itself or starch that is crushed and kneaded into emulsion and mixed at a high ratio of 30 to 60% by weight. Since the sheet material is molded by vacuum or blow molding means, the starch mixed at a high ratio causes the burning calories at the time of combustion to be significantly larger than in the case of only synthetic resin materials such as polypropylene. In addition, it is possible to reduce the number of calories and reduce the adverse effect on the incineration facility, reduce the amount of toxic gas generation, and promptly weathering and natural decomposition by microorganisms when dumped as garbage. Therefore, it can contribute greatly to the social problem of improving environmental pollution, and in particular, starch itself is highly lubricious. Because of its quality, the use of this has the advantage that the sheet material can be easily molded even if it is blended at a high ratio, and since starch itself is a powder, it can be used as it is. There is an advantage that the sheet material and the molding container can be manufactured by using only the existing synthetic resin molding machine without requiring a process or equipment for the production.
