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,
an inner skirt depending from the upper deck, said inner skirt being configured and arranged to attach to a squeezable product container, and
a flow conduit extending upwardly from said upper deck to provide a flow path from an interior of said closure to an exterior of said closure,
said flow conduit and said closure body being integrally formed,
said flow conduit including an exit orifice,
said exit orifice being configured and arranged to produce a fan-shaped discharge when a force of 0.3 psi to 5 psi is applied to said squeezable product container, wherein a shape of said exit orifice is selected from a group consisting of rectangular, bowtie, half bowtie, oval, keyhole, dumbbell, and curved rectangular,
said flow conduit including a tip portion, said tip portion having a semi-spherical surface having an interior volume to collect liquid before said liquid exits through said exit orifice, wherein said semi-spherical surface is an integral raised convex surface of said flow conduit, wherein said exit orifice extends through, and along, said semi-spherical surface of said tip portion along an arc,
said dispensing closure further comprising a sealing structure cooperating with exit orifice to prevent liquid from exiting therethrough, wherein said sealing structure comprises a sealing wedge on said closure lid, said sealing wedge extending along a semi-spherical arc, said sealing wedge being received within 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 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-shaped discharge.
4. 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 a deck, an inner skirt depending from the deck, said inner skirt being configured and arranged to attach to a squeezable product container,
an outer skirt depending from said deck, said outer skirt concentrically spaced from and surrounding said inner skirt,
a flow conduit extending upwardly from said deck to provide a flow path from an interior of said closure to an exterior of said closure,
said flow conduit and said closure body being integrally formed,
said flow conduit including an exit orifice,
said exit orifice being configured and arranged to produce a fan-shaped discharge when a force of 0.3 psi to 5 psi is applied to said squeezable product container, wherein a shape of said exit orifice is selected from a group consisting of rectangular, bowtie, half bowtie, oval, keyhole, dumbbell, and curved rectangular,
said flow conduit including a tip portion, said tip portion having a semi-spherical surface having an interior volume to collect liquid before said liquid exits through said exit orifice, wherein said semi-spherical surface is an integral raised convex surface of said flow conduit, wherein said exit orifice extends through, and along, said semi-spherical surface of said tip portion along an arc,
said dispensing closure further comprising a sealing structure cooperating with exit orifice to prevent liquid from exiting therethrough, wherein said sealing structure comprises a sealing wedge on said closure lid, said sealing wedge extending along a semi-spherical arc, said sealing wedge being received within said exit orifice when said closure lid is in a closed position,
said dispensing closure further comprising a child-resistant latch mechanism releasably latching said closure lid to said closure body, said latch mechanism comprising diametrically opposed hook members on said closure lid, diametrically opposed hook arms extending upwardly from said deck of said closure body, said hook arms engaging with said hook members when said closure lid is in said closed position, said hook arms disengaging from said hook members when diametrically opposed sides of said outer skirt, beneath said hook arms, are squeezed inwardly, thereby moving said hook arms outwardly.
5. The dispensing closure of claim 4 , 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-shaped discharge.
