た。Conventional containers of this type have strict standards set by the Ministry of Health and Welfare, and are required to pass certain tests. However, even if the product complies with the Ministry of Health and Welfare standards, the contents will be irradiated by the light that has passed through the body, and the active ingredients such as vitamin BS in the contents will be degraded by the outer layer of light. In some cases, the contents may become discolored. Therefore, on the surface of the container, the voting agent (
benzotriazole, hydroxybenzophenone, etc.)
Some methods have been considered, such as coating the container with a resin, or mixing a cable outer ring absorbent into the container material itself. However, if the former method is adopted, the cost of the resin to be coated and the cost of the labor involved in coating are added, resulting in high costs, and the appearance is also unsightly, so the arrogant method is adopted. In such a case, depending on the type of contents, there is a risk that the cable outer ring absorbent may be eluted into the contents, so there is a need for the same layer in terms of safety and stability.

) and -14 polybutylene terephthalate (PBT) bags are also reusable parts. In addition, it is a polyarylate resin consisting of a thermoplastic derivative and a dihydric phenol or its derivative, and the structurally rigid aromatic nucleus has a mobile ester bond (because it is a more connected structural unit, basically It is an extremely strong and heat-resistant plastic, with the general formula % weight percent thermoplastic aromatic polyester 1°5~
The 10% by weight mixture provides better UV protection for contents containing components that are sensitive to specific ultraviolet light, such as vitamin B@, than either of them alone, and better than polycarbonate, etc., conventionally commonly used for eye drop containers. It is excellent in terms of functions such as yellowing of the container itself, deflection due to molding, and residual amount of adsorption of ethylene oxide gas (EOG) used in rough curvature. It is possible to suppress the whitening phenomenon while taking advantage of the advantages of
For example, 0 containing vitamin Bc-B1f1 sulfonate, etc.
Through repeated experiments, the inventors of the present invention discovered and confirmed that it is particularly suitable as a container for chickens! Shita. Example 1 - Aromatic polyester (hereinafter abbreviated as PC) 1.5■

。Furthermore, it has been found that even in the same container made of a mixture of APC and PET, the effects of ultraviolet rays are greater in those that are exposed to a weather meter for 48 hours and those that are not exposed to a weather meter. That is, as shown in Fig. 2, among plastic containers formed from a mixture of 6% APC and 94% PET, a container irradiated with ultraviolet rays with an I-sermeter for 10 to 48 hours has a curve sx. In a container that does not irradiate ultraviolet light (1

The t-line was also irradiated with ultraviolet rays in advance, and it was found that containers containing APC were more effective at preventing the transmission of ultraviolet rays than containers that were not irradiated with ultraviolet rays or containers made only of PET.

開後の結果は第２表並びに第４図に示す通りである。Furthermore, since the container according to the present invention contains polyalkylene terephthalate of 90% or more, polyalkylene terephthalate lacks heat resistance due to its properties. Therefore, the container according to the present invention is subjected to EOG (ethylene oxide gas) sterilization. EOG sterilization is toxic, and the EOG attached to the container is completely removed. However, in the case of the present invention (11W made from a mixture of polyfulkylene terephthalate and thermoplastic aromatic polyester in a predetermined ratio), the amount of EOG adsorption remaining is extremely small. The results of the experiment were ascertained.The results after the aeration started at 2.5 o'clock are shown in Table 2 and Figure 4.

On the other hand, in two-wheel stretch blow molding, the material strength is increased due to the stretching effect of the plastic material, giving the molded volume sufficient mechanical strength and excellent gas barrier properties against oxygen, carbon dioxide, etc. It has many excellent properties such as Therefore, there is a demand for containers for eye drops and the like that are formed by two-wheel stretch blow molding. However, in the case of two-wheel stretch blow molding, when the mixing ratio of APC is increased, it has been found that the molded container (whitening phenomenon and uneven thickness) and loses its commercial value. In blow molding, whitening did not occur even if the mixing specific gravity of APC was considerably increased (more than 50%).Therefore, the present inventors made use of the characteristics of two-wheel stretch blow molded products and developed In order to take full advantage of this and create a container with high commercial value, we repeated the experiments. The results are shown in Table 3 below. It is based on the four levels of white and oxidation.

利点を有する。As explained above, according to the present invention, when the content contains components unstable to ultraviolet light such as vitamin Bε, these components have excellent photostability and the color of the solution containing these components is improved. It has the characteristic that it does not change. Also,
Since the container itself contains a thermoplastic aromatic polyester in a range of 1.5 to 10 percent, it is resistant to yellowing and whitening, and has an excellent appearance. Furthermore, it has the advantage that safety can be ensured even if EOG is reduced. Furthermore, it has the advantage that uneven thickness is less likely to occur.
