我国生产的玻璃食品罐头,长期来大量沿用500mL 卷封式胜利瓶,开盖困难,消费者普遍反映“罐头好吃,盖难开”,影响市场销售。为此,决定改革玻璃瓶封盖形式,采用国外普遍使用的旋开式玻璃罐,逐步淘汰胜利瓶。国家机械委下达了国家科委星火计划 The canned glass food produced in China has used a large amount of bottled sealed bottle of victory for 500 mL for a long period of time. It is difficult to open the lid. Consumers generally believe that “canned food is good and the lid is hard to open”, which affects market sales. To this end, it was decided to reform the glass bottle closures, and the use of spin-open glass cans, which are commonly used in foreign countries, will gradually eliminate successful bottles.
