藥廠當局對藥物製造的技術性问题經常很注意研究改進,但對製成品包裝時所用的軟木塞,往往認為是小問題不甚注意。液體藥品在瓶中久存變質,軟木塞使用不得當,常是主要原因之一。談談這個小問題可能引起廠方注意。軟木塞是用木栓槠树(Quercus Suber)的栓皮製成,在樹齡達15—20年栓皮厚度增加達適當程度時, The pharmaceutical authorities often pay attention to research and improvement on the technical problems of drug manufacturing. However, the cork stoppers used in the packaging of finished products are often considered to be minor problems. The long-term deterioration of liquid medicines in bottles and the improper use of cork stoppers are often one of the main reasons. Talking about this small issue may cause the factory to pay attention. Cork is made of cork of Quercus Suber, and when the age of the cork is increased by 15-20 years, the thickness of the cork is increased to an appropriate degree.
