Abstract

A dispensing closure has a key-hole shaped 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 and lower deck, inner and outer skirt, and a flow conduit extending through the upper deck. The outer skirt is configured to mount to a product container. The flow conduit includes including two or more vertically oriented walls and a bottom wall. The bottom wall configured and arranged to be positioned along a horizontal axis. The flow conduit includes one or more entrance orifices having one or more entrance axes 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.
