发明名称 Dispensing closure with spout vent
摘要 A closure for a fluid product dispensing package that includes a tubular body for securement to a container, and having a central flow passage and a cylindrical peg axially spaced from the flow passage. A spout has a dispensing orifice, and is mounted on the base for movement between an open position in which the dispensing orifice is axially spaced from the peg to permit product flow through the passage around the peg and through the orifice, and a closed position in which the dispensing orifice closely surrounds the peg to block product flow. The dispensing orifice is circular, and has three angularly spaced recesses extending radially outwardly from and arcuately around the opening forming air vents with the peg in the closed position of the spout.
