この発明は包装用容器として使用されるポリエチレンテ
レフタレート樹脂製の二軸延伸容器に関するものである
。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a biaxially stretched container made of polyethylene terephthalate resin used as a packaging container.
（従来の技術）
この種の二軸延伸容器は、ポリエチレンテレフタレート
樹脂を加熱溶融し、その溶融樹脂を金型に田川するか、

で成形される。(Prior art) This type of biaxially stretched container can be made by heating and melting polyethylene terephthalate resin and pouring the molten resin into a mold.
Alternatively, a parison is formed by extrusion, and then the parison is stretched in the axial direction in a blow mold, and air is blown into the mold.

を内の樹脂通路の改善によって発生量を少なくすること
は出来るが、全く無くすことは不可能とされている。Polyethylene Derephthalate 1 - FA resin tends to generate acetaldehyde when heated and melted. The amount of acetaldehyde generated varies depending on the heating and melting state of the resin, and it is possible to reduce the amount generated by improving the resin passage inside the gold. It is possible, but it is impossible to completely eliminate it.

におけるアセトアルデヒドの発生をルカ低減することが
・及望されている。This acetaldehyde does not have any adverse effects on the human body as long as it remains in a small amount, but it has a unique pungent odor, and if the contents are edible oil or carbonated drinks, it can have a subtle effect on the taste, especially The effect is noticeable when drinking only 1 water. For this reason, polyethylene terephthalate resin
It is desired to reduce the generation of acetaldehyde in

な構成の二軸延伸容器を提供することにある。This invention was devised to solve the above-mentioned conventional problems, and its purpose is to be able to suppress the generation of acetaldehyde using extremely simple means, and to specifically change the molding means. An object of the present invention is to provide a biaxially stretched container with a new configuration that is not necessary.

ない。The above two resins are simultaneously heated and melted and kneaded in the barrel of the injection device. In addition, the heating temperature may be around 270℃ in terms of barrel temperature, and the heating temperature should be around 270℃.
After passing through a hot runner mold maintained at around 65°C, it is injected into a parison mold. During this injection, the two resins form a plurality of layers due to the difference in fluidity, but this does not impair the reduction of ace1-aldehyde.

It expands and becomes a two-wheeled stretched container.

Since no special means are required to form the container, the cost of the container does not increase.
