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.

Claims (44)

1. 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.

2. The dispensing closure of claim 1 , wherein said plurality of arms comprise at least four depending arms equally spaced around a peripheral edge of said bottom wall.

3. The dispensing closure of claim 2 , wherein said at least one entrance orifice is at least four entrance orifices.

4. The dispensing closure of claim 1 , wherein the one-piece dispensing closure is made by process of injection molding.

5. The dispensing closure of claim 1 , wherein the outer skirt is internally threaded for attachment to a product container.

6. The dispensing closure of claim 1 , wherein said upper deck is tiered near said exit orifice.

7. The dispensing closure of claim 1 , wherein said exit orifice is located on exterior of said product container.

8. The dispensing closure of claim 1 , wherein said lid includes a circular wall depending from an inner surface of said lid to close said exit orifice.

9. The dispensing closure of claim 1 , wherein said entrance orifice is located within an interior of said product container.

10. The dispensing closure of claim 1 , wherein said flow conduit has a diameter substantially less than the diameter of the upper deck.

11. The dispensing closure of claim 1 , wherein said upper deck has a surface area equal to a horizontal cross-sectional surface area of product container neck.

12. The dispensing closure of claim 1 , wherein said inner skirt extends below said entrance orifice.

13. The dispensing closure of claim 1 , wherein said flow conduit includes a portion extending above and below said upper deck.

14. 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 to a product container;

a flow conduit extending through said upper deck, said flow conduit including a portion extending above and below said upper deck, said flow conduit including at least 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 and extending below said at least one entrance orifice.

15. 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 to a product container;

a flow conduit extending through said upper deck, said flow conduit including a portion extending above and below said upper deck, said flow conduit has a diameter substantially less than the diameter of said upper deck, said flow conduit including at least 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 and extending below said at least one entrance orifice.

16. The dispensing closure of claim 15 , wherein said exit orifice is located on exterior of said product container.

17. The dispensing closure of claim 16 , wherein said entrance orifice is located within an interior of said product container.

18. The dispensing closure of claim 17 , wherein said upper deck has a surface area equal to a horizontal cross-sectional surface area of product container neck.

19. The dispensing closure of claim 18 , wherein the outer skirt is internally threaded for attachment to a product container.

20. The dispensing closure of claim 19 , wherein a portion the flow conduit and the inner skirt extend below the upper deck to a substantially similar horizontal plane.
