て２倍近い残存量が確認された。In each Example of the first invention, polyethylene was used as the soft synthetic resin, and tocopherol acetate as vitamin E was kneaded into the polyethylene to form an inner plug of a desired shape. Tocopherol acetate is a viscous liquid, and this liquid is kneaded with polyethylene, used as a molding material, and the inner plug is molded by means such as injection molding. The proportion (%) of tocopherol acetate in the entire molded inner plug is 0.
゜1.0.3.0.75.1.5.2.0.2,5.3
．． 0 of each were manufactured. The container body is molded from a hard synthetic resin material such as polyethylene terephthalate, which is chemical resistant and does not adsorb vitamin E, and an inner stopper molded from the above-mentioned soft synthetic resin material containing vitamin E is fitted into the mouth of the container body. I let it happen. Since the inner plug is soft, it not only fits well with the mouth part, but also has excellent fit with the cap.
It also had excellent sealing properties with the mouth and cap. As a result of storing a drug solution containing vitamin E in such a container and leaving it for 24 hours (50℃) with the drug solution touching the inner stopper, it was found that even if the inner stopper contained 0.1% vitamin E, the drug solution It was confirmed that the amount of vitamin E remaining in the bottle was almost twice that of the inner stopper that did not contain any vitamin E.

ールすることが容易に行えることが判明した。As is clear from this table and drawing, the relationship between the amount of vitamin E kneaded and the remaining amount is proportional, and by controlling the amount of kneaded, it is easy to control the amount of vitamin E remaining in the medicinal solution. It has been found.
この測定結果から、第２の発明は、ビタミンＥの練込量
を２〜２．５％とし、残存量の増減を１０％未満にコン
トロールした。From this measurement result, in the second invention, the kneaded amount of vitamin E was set at 2 to 2.5%, and the increase/decrease in the remaining amount was controlled to less than 10%.

Obtain pellets in the same manner as in the production example above, but first make concentrated pellets with the amount of vitamin E about 10 times greater than the final desired amount, and knead the pellets with natural polyethylene pellets. Then, an inner stopper into which a predetermined amount of vitamin E was kneaded was obtained by injection molding. This manufacturing example prevents color unevenness and uses polyethylene and vitamin E.
The ratio can be adjusted more accurately.
