Delayed flow baffled dispensing closure
A dispensing closure having a closure body and an insert member for dispensing a product from a container. The insert member includes a base and a sealing tube. The base is configured and arranged for seating within an open end of the product container. The sealing tube extends upwardly from the base. The sealing tube has a sealing tip portion at an upper end thereof. The sealing tube further includes one or more baffles spaced apart along the sealing tube. Each of the baffles positioned along a different horizontal axis to restrict direct flow of a product out of the dispensing closure. In operation, the closure body moves relative to the relative to the insert member between a closed position to prevent a baffled flow product to exit the exit orifice area and an open position to allow a baffled flow of product to exit the exit orifice area.
1. A dispensing closure for a product container having an outwardly threaded neck, comprising:
an insert member including
a base configured and arranged to be received in interfitting seated engagement within the threaded neck of the container,
a sealing tube extending upwardly from the base, said sealing tube having a sealing tip portion at an upper end thereof; and
a closure body including,
an upper deck,
a skirt depending downwardly from the upper deck and having a threaded internal surface at an upper portion thereof which is configured and arranged to threadedly engage with the threaded neck of said container, said closure body being rotatably movable relative to said neck,
a flow conduit extending from the upper deck to provide a flow path from an interior of the closure to an exterior of the closure,
said flow conduit having a dispensing tip portion,
said flow conduit including an entrance orifice and an exit orifice, said exit orifice at said dispensing tip portion,
said flow conduit has an inner wall extending between the entrance orifice and the exit orifice,
said closure body being rotatably movable relative to said base between a closed position wherein said sealing tip portion of said sealing tube matingly engages said inner wall of said flow conduit in the area of said dispensing tip and prevents a flow of liquid from exiting said exit orifice, and an open position wherein said inner wall of said flow conduit in the area of said dispensing tip portion is spaced from said sealing tip portion of said sealing tube and allows a flow of fluid to exit said exit orifice,
said sealing tube further including a plurality of semi-circular baffles radiating outward from said sealing tube whereby a terminal outer edge thereof engages with said inner wall of said flow conduit to restrict flow through said flow conduit, each of said plurality of baffles being spaced apart along a longitudinal extent of the sealing tube and radiating outwardly in offset circumferential positions on different horizontal planes to prevent any direct flow of a product through the flow conduit from the entrance orifice to the exit orifice.
2. The dispensing closure of claim 1 , wherein said closure body includes a stop mechanism configured to stop rotation of said closure body in said open position.
3. The dispensing closure of claim 1 , wherein each of said plurality of baffles defines a semi-circular half-moon shape.
4. The dispensing closure of claim 2 , wherein each of said plurality of baffles defines a semi-circular half-moon shape.
