    • A container for carbonated beverages is disclosed. The container includes an interlocking plastic lid and plastic can construction wherein the lid snaps onto the can to provide a sealed container capable of withstanding high internal pressure without leakage. The can includes a neck portion having an inwardly extending ridge and an outwardly flared mouth thereabove. An outwardly and downwardly extending locking flange is unitarily formed at the top of the can mouth. the lid includes a concave top wall which fits into the can mouth and engages the ridge, and a peripheral rim which includes a downwardly opening groove to receive the locking flange. The lid is rigid, and is shaped to compress the locking flange as the lid is pressed onto the can, with the locking flange snapping outwardly over an annular shoulder to secure the lid in place. The flange is held in compression by the groove to insure an intimate surface-to-surface seal around the circumference of the can, the rigid lid providing sufficient hoop strength to maintain the shape of the container, even under high internal pressures.
    • 公开了一种用于碳酸饮料的容器。 容器包括互锁塑料盖和塑料罐结构,其中盖子卡在罐上以提供能够耐受高内压而不泄漏的密封容器。 罐包括一个颈部,该颈部具有向内延伸的脊和在其上方的向外扩张的口。 向外和向下延伸的锁定凸缘一体地形成在罐口的顶部。 盖子包括凹入的顶壁,该顶壁装配到罐口中并与脊接合,外周边缘包括向下开口的凹槽以容纳锁定凸缘。 盖是刚性的,并且被成形为当盖被压到罐上时压缩锁定凸缘,其中锁定凸缘向外咬合在环形肩部上以将盖固定在适当位置。 凸缘通过凹槽保持压缩以确保围绕罐的圆周的紧密的表面到表面密封,即使在高内部压力下,刚性盖也提供足够的箍筋强度以保持容器的形状。
