    • A method of molding a container closure providing selective fluid communication between an interior of a fluid container and an exterior environment, the method comprising: (i) configuring and closing a mold having a first cavity negatively defining a base of a container closure that includes a spout and a container mount, where the spout and container mount cooperate to define a conduit therethrough in fluid communication with an outlet orifice of the spout; (ii) injecting a first material into the first cavity to mold the base; (iii) cooling the first material in the mold to impart at least minimal rigidity to the base; (iv) reconfiguring at least a portion of the mold to define a second cavity adjacent to the first material, the second cavity negatively defining a cap covering the outlet orifice of the spout; (v) injecting a second material into the second cavity to mold the cap over the outlet orifice; (vi) cooling the second material in the mold to impart at least minimal rigidity to the cap; and (vii) removing the base and integrally formed cap from the mold.
    • 一种模制容器封闭件的方法,所述容器封闭件在流体容器的内部和外部环境之间提供选择性的流体连通,所述方法包括:(i)配置和关闭具有负面地限定容器封闭件的基部的第一腔的模具, 喷嘴和容器安装件,其中喷口和容器安装件协作以限定通过其与喷口的出口孔流体连通的导管; (ii)将第一材料注入所述第一腔体以模制所述基底; (iii)冷却模具中的第一材料以赋予基底至少最小的刚性; (iv)重新配置所述模具的至少一部分以限定与所述第一材料相邻的第二腔,所述第二腔负极地限定覆盖所述喷口的出口孔的盖; (v)将第二材料注入所述第二腔中以在所述出口孔上模制所述盖; (vi)冷却模具中的第二材料以赋予帽至少最小的刚性; 和(vii)从模具移除基部和一体形成的盖。
