Dispensing closure having a flow conduit with key-hole shape

1. A one-piece dispensing closure for a viscous food condiment comprising:

a closure body; a closure lid; and a living hinge structure hingeably 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 mount to a product container; and

a flow conduit extending through said upper deck, said flow conduit having a sidewall and a bottom wall, said flow conduit including an entrance orifice in the bottom wall having an entrance axis and an exit orifice having an exit axis, said bottom wall being configured and arranged to prevent the flow of product into the flow conduit along the exit axis, said bottom wall having a surface area proportionally sized to the surface area of the exit orifice to prevent direct flow of product out of exit orifice, said entrance axis being stepped from said exit axis whereby said flow conduit provides a non-linear flow path from an interior of said closure to an exterior of said closure, said entrance axis being parallel to said exit axis, said entrance orifice being larger than said exit orifice,

said bottom wall and said sidewall of said flow conduit defining an interior volume when viewed in a cross-section extending perpendicular to the entrance and exit axes,

said cross-sectional area of said interior volume being larger than the cross sectional area of said entrance orifice wherein a flow of viscous food condiment through said entrance orifice decelerates into said interior volume of said flow conduit to prevent direct spurting through said exit orifice upon dispensing, said food condiment being dispensed without spurting through said exit orifice upon filling of the interior volume and the application of additional pressure to said food condiment.

2. The dispensing closure of claim 1 , wherein said flow conduit has a non-uniform volume extending from the entrance orifice to the exit orifice, said entrance orifice expanding into an interior volume larger than the interior volume of the exit orifice.

3. The dispensing closure of claim 1 , wherein said flow conduit has a portion extending above and below said upper deck, said flow conduit portion extending below said upper deck defining a key-hole shape.

4. The dispensing closure of claim 1 , wherein said flow conduit has at least two sidewalls positioned along a 90 degree angle depending downwardly from said upper deck, said at least two sidewalls directly opposing one another; and a bottom wall perpendicular to said at least one sidewall.

5. The dispensing closure of claim 1 , wherein said flow conduit extends through an opening in said upper deck, said opening is concentric to said surface of said upper deck.

6. The dispensing closure of claim 1 , further comprising:

a recess area entirely surrounding an outer surface of said flow conduit extending below said upper deck.

7. The dispensing closure of claim 6 , wherein a height of said side wall is about the height of said recess area.

8. The dispensing closure of claim 1 , further comprising:

a first and second upper deck, said first upper deck including said opening for exit orifice; and

an inner skirt depending from said first upper deck and an outer skirt depending from said second upper deck.

9. The dispensing closure of claim 1 , wherein the living hinge structure is a dual living hinge structure comprising:

a first living hinge joining a first end of a hinge body to said outer surface of said skirt, said hinge body being hingeably movable from an open position to a closed position in facing mating relation with said skirt, said hinge body and said skirt including interfitting mating formations to secure said hinge body in facing mating relation with said skirt; and

a second living hinge joining a second end of said hinge body to said closure lid, said closure lid being hingeably movable from an open position to a closed position.

10. The dispensing closure of claim 1 , wherein the upper deck defines an arcuate shape.

11. A one-piece dispensing closure for a viscous food condiment comprising:

a closure body, said closure body including an upper deck, a skirt depending from the upper deck, said skirt being configured and arranged to mount to a product container;

a flow conduit extending through an opening in said upper deck, said flow conduit including a portion extending above and below said upper deck, said flow conduit has a first wall positioned substantially perpendicular to said upper deck and a second wall positioned substantially perpendicular to said first wall, said flow conduit including an entrance orifice in the second wall having an entrance axis and an exit orifice having an exit axis, said second wall being configured and arranged to prevent the flow of product into the flow conduit along the exit axis, said second wall has a surface area proportionally sized to the surface area of the exit orifice to prevent direct flow of product out of the exit orifice, said entrance axis being stepped from said exit axis whereby said flow conduit provides a non-linear flow path from an interior of said closure to an exterior of said closure, said entrance axis being parallel to said exit axis,

said flow conduit portion extending from said upper deck, said second wall and said first wall of said flow conduit defining an interior volume when viewed in a cross-section extending perpendicular to the entrance and exit axes, and

said cross-sectional area of said interior volume being larger than the cross-sectional area of said entrance orifice wherein a flow of viscous food condiment through said entrance orifice decelerates into said interior volume of said flow conduit to prevent direct spurting through said exit orifice upon dispensing, said food condiment being dispensed without spurting through said exit orifice upon filling of the interior volume and the application of additional pressure to said food condiment.

12. The dispensing closure of claim 1 , wherein said bottom wall and said sidewall of said flow conduit defining an interior volume has a general shape of a key-hole when viewed in a cross-section extending perpendicular to the entrance and exit axes.

13. The dispensing closure of claim 11 , wherein said flow conduit portion extending from said upper deck defining a key-hole shape, said second wall and said first wall of said flow conduit defining an interior volume that has the general shape of a key-hole when viewed in a cross-section extending perpendicular to the entrance and exit axes.

14. A dispensing closure for a viscous food condiment comprising:

a closure body; a closure lid; and a hinge structure hingeably 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 mount to a product container; and

a flow conduit extending through said upper deck, said flow conduit having a sidewall and a bottom wall, said flow conduit including an entrance orifice in the bottom wall having an entrance axis and an exit orifice having an exit axis, said bottom wall being configured and arranged to prevent the flow of product into the flow conduit along the exit axis, said bottom wall having a surface area proportionally sized to the surface area of the exit orifice to prevent direct flow of product out of exit orifice, said entrance axis being stepped from said exit axis whereby said flow conduit provides a non-linear flow path from an interior of said closure to an exterior of said closure, said cross-sectional area of said interior volume being larger than the cross-sectional area of said entrance orifice wherein a flow of viscous food condiment through said entrance orifice decelerates into said interior volume of said flow conduit to prevent direct spurting through said exit orifice upon dispensing, said food condiment being dispensed without spurting through said exit orifice upon filling of the interior volume and the application of additional pressure to said food condiment.
