ABSTRACT:
An improved dispensing closure system for dispensing a product from a container includes an elongate or oblong dispensing orifice for dispensing a ribbon of product. One form of the dispensing closure system also includes a spout having a dispensing orifice that is oriented at an angle relative to the closure deck and relative to the flow direction of product from the orifice. The closure provides for the dispensing of product in a clean and controlled manner without mess. One form of the closure system also incorporates conical geometries in transition surfaces extending from the container opening to the dispensing orifice. The conical geometries of the transition surfaces provides for a smooth transition of product flow from the container opening to the dispensing orifice, while minimizing the volume defined by the closure system spout and thereby providing increased “suck-back” and an abrupt “cut-off” of product compared to prior art devices.
