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; anda hinge connecting said closure lid to said closure body,said closure body includingan upper deck,a skirt depending from the upper deck, said skirt being configured and arranged to attach to a product container, anda flow conduit extending from said upper deck, said flow conduit including a tip portion at a terminal end thereof,said flow conduit and said closure body being integrally formed,said flow conduit including an entrance orifice within said closure body and an exit orifice within said dispensing tip portion,said flow conduit having an inner wall extending between said entrance orifice and said exit orifice to provide a flow path from an interior of said closure to an exterior of said closure,said tip portion having a convex outer surface and a corresponding concave inner surface defining an interior volume to collect liquid before said liquid exits through said exit orifice at less than 5 psi,said tip portion and 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 dispensing closure further comprising a seal structure cooperating with said tip portion to prevent liquid from exiting therethrough. 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. 6. The dispensing closure of claim 1, wherein said tip portion of said flow conduit has a relatively uniform thickness of material between said outer convex surface and said inner concave surface. 7. The dispensing closure of claim 1, wherein said flow conduit defines a gradually decreasing diameter as it extends from an interior of said dispensing closure, through said upper deck and to said tip portion.
