The bottom wall configured and arranged to be positioned along a horizontal axis. The flow conduit includes one entrance orifice having one entrance axis and an exit orifice having an exit axis. The entrance axis is stepped or offset from the exit axis whereby the flow conduit provides a non-linear flow path of product from an interior of the closure to an exterior of the closure.
