A closure for a container, and a container incorporating the same, that minimizes or eliminates leakage between the closure and the container holding the liquid. The closure provides a liquid sealing system that allows irregularly shaped closure tops to be used without sacrificing the effectiveness
A closure for a container, and a container incorporating the same, that minimizes or eliminates leakage between the closure and the container holding the liquid. The closure provides a liquid sealing system that allows irregularly shaped closure tops to be used without sacrificing the effectiveness of the liquid seal. In one embodiment, the closure includes a plurality of struts disposed within an annular space that receives a neck portion of the container to create a seating plane that corresponds to a plane formed by the rim of the neck portion.
