Abstract
A dispensing closure has a 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 deck and a flow conduit extending through the upper deck. The flow conduit includes an entry orifice having an entrance axis and an exit orifice having an exit axis. The entrance axis is offset from the exit axis to provide a non-linear flow path from an interior of the closure to the exterior of the closure.
Claims20
A one-piece dispensing closure comprising:
- a closure body;
- a closure lid;
- a living hinge structure hingeably connecting said closure lid to said closure body,
- said closure body including an upper deck;
- an outer skirt depending below the upper deck, said outer skirt being configured and arranged to mount a product container;
- a flow conduit extending through said upper deck, said flow conduit including more than one entrance orifice having an entrance axis and a single exit orifice having an exit axis, said entrance axis being perpendicular to said exit axis, said flow conduit having a substantially horizontal bottom wall suspended beneath said upper deck by a plurality of substantially vertical arms depending downwardly from said upper deck, said bottom wall having an area about the same as a cross-sectional area of the flow conduit taken along a plane parallel to the entrance axis, wherein said bottom wall baffles direct flow from an interior of said product container through said exit orifice;
- and
- an inner skirt depending below the upper deck, said inner skirt being spaced radially inwardly from said outer skirt away from a sidewall of said product container,
- said inner skirt encircling said flow conduit.
