  • Patent number: 8038041
    Abstract: A dispensing closure has a flow conduit that provides a sufficient flow restriction to prevent unwanted spurting of the product when the container is initially opened. The dispensing closure includes a closure body with an upper deck and a flow conduit extending through the upper deck. The flow conduit includes an entry orifice having an entrance axis and an exit orifice having an exit axis. The entrance axis is offset from the exit axis to provide a non-linear flow path from an interior of the closure to the exterior of the closure.
