    • A two stage dispensing cap for a carbonated beverage container is described. The cap has a flip top which is hingedly connected to a collar wherein the collar is rotatable on the container. The cap, upon rotation of the collar, is first opened into a venting position wherein the flip top vents the pressurized contents of the container but remains locked partially closed. Continued rotation of the cap releases the locked flop top to allow the container to be fully opened. A set of cams on the container neck work in conjunction with annular beads to first allow partially opening of the flip top into the venting position and then allowing it to fully open.
    • 描述了用于碳酸饮料容器的两级分配帽。 盖具有铰接地连接到轴环的翻盖,其中轴环可以在容器上旋转。 盖子在套环旋转时首先被打开到排气位置,其中翻盖将容器的加压内容物排出,但保持锁定部分关闭。 盖的继续旋转释放锁定的翻盖顶部以允许容器完全打开。 容器颈部上的一组凸轮与环形珠一起工作,首先允许将翻盖部分地打开到排气位置,然后使其完全打开。

    • A mating closure and finish system particularly adapted for use with containers, e.g. bottles containing carbonated beverages which generate gas in the bottle headspace and where the bottle finish incorporates at least two equally spaced helical cam tracks. The closure is comprised of plural sets of cam followers which fit into the cam tracks and where the cooperation between the cam tracks and cam followers produces an axial movement of the closure as it is rotated on the finish. For a two track system, which is the preferred embodiment, each track starts 180.degree. from each other and makes at least one full turn around the circumference of the finish. Also included are intervening stops and tapered speed bumps that contact and impede the cam follower(s) in the cam tracks during closure removal to effect a delay. Raised thread segments which define the cam tracks are intersected by a plurality of vertical venting slots or pathways along their helical length to vent headspace gas. Longitudinally extending grooves are located in raised thread segments on either side of the cam tracks and couple with the vertical venting slots to provide a continuous venting conduit of the headspace gas. Anti-backoff devices are furthermore provided which operate when the closure is seated on the finish to keep the closure from backing off the finish and leaking prior to closure removal.
    • 特别适合与容器一起使用的配合封闭和整理系统,例如。 包含在瓶顶部空间中产生气体的碳酸饮料的瓶子,并且瓶口装配有至少两个等间隔的螺旋形凸轮轨道。 封闭件包括多组凸轮从动件,这些凸轮从动件装配到凸轮轨道中,并且凸轮轨道和凸轮从动件之间的配合在闭合件在端面上旋转时产生轴向运动。 对于作为优选实施例的双轨系统,每个轨道彼此相差180度,并且围绕整饰圆周进行至少一个完整的转弯。 还包括中断止动器和锥形速度凸块,其在闭合件移除期间接触和阻止凸轮轨道中的凸轮从动件以实现延迟。 限定凸轮轨道的凸起螺纹段由沿其螺旋长度的多个垂直排气槽或通道相交,以排出顶部空间气体。 纵向延伸的凹槽位于凸轮轨道两侧的凸起螺纹段中,并与垂直排气槽相连,以提供顶部空间气体的连续排气导管。 此外还提供防退货装置,当闭合件位于精加工上时,其操作以在封闭件移除之前保持封闭件免于脱模并泄漏。
