Fan orifice dispensing closure
A dispensing closure for a squeeze-type container produces a fan-type spray in a low pressure environment. The dispensing closure includes a closure body having an upper deck and a skirt depending from the upper deck. The skirt is configured and arranged to attach to a product container, such as a squeeze-type container. A flow conduit extends from an interior of the closure body and through the upper deck to provide a flow path from an interior of the closure to an exterior of the closure. The flow conduit has an entrance orifice and an exit orifice. The flow conduit has an inner wall extending between the entrance orifice and the exit orifice. The flow conduit and the closure body are integrally formed. The flow conduit includes a tip portion with an exit orifice defining a shape to provide a fan-type spray in a low pressure environment.
1. A dispensing closure, comprising:
a closure body;
a closure lid; and
a hinge connecting said closure lid to said closure body,
said closure body including
an upper deck,
a skirt depending from the upper deck, said skirt being configured and arranged to attach to a product container, and
a flow conduit extending from said upper deck to provide a flow path from an interior of said closure to an exterior of said closure,
said flow conduit including an entrance orifice and an exit orifice,
said flow conduit and said closure body being integrally formed,
said flow conduit having an inner wall extending between said entrance orifice and said exit orifice,
said exit orifice being configured and arranged to produce a fan-type discharge in a low-pressure environment, wherein a shape of said exit orifice is selected from a group consisting of: rectangular, bowtie, half bowtie, oval, keyhole, dumbbell, curved rectangular, “J”, “T”, inverted “T”, inverted “J”, and other non-circular shapes,
said flow conduit including a tip portion, said tip portion having a non-planar surface having an interior volume to collect liquid before said liquid exits through said exit orifice at less than 5 psi, wherein said non-planar surface is a raised surface of said flow conduit,
said dispensing closure further comprising a seal structure cooperating with said exit orifice to prevent liquid from exiting therethrough, wherein said sealing structure comprises a sealing wedge positioned on an interior surface of the closure lid, said sealing wedge being received in engagement with said exit orifice when said closure lid is in a closed position.
2. The dispensing closure of claim 1 , further comprising:
a latch mechanism releasably latching said lid to said body.
3. The dispensing closure of claim 2 , wherein said latch mechanism is a child-resistant latch mechanism.
4. The dispensing closure of claim 1 , wherein the tip portion defines a width (A), depth (C), and radius (B) of said exit orifice which are adjustable according to the viscosity of the liquid and desired dimension of the fan-type discharge.
5. The dispensing closure of claim 1 , wherein the dispensing closure is a one-piece dispensing closure.
