Abstract

A one-piece dispensing top has three separate dispensing ports. Each dispensing port is designed to dispense particulate foodstuffs from a container. One port is configured to allow removal of product with an utensil. A second port is configured to be used for pouring product and includes a spout, and a third port is configured for sifting product. Each dispensing port includes a closure flap for sealing. All three closure flaps are integrally joined to the dispensing top via living hinges. The closure flaps may be retained in the closed position by a friction or snap fit.

Claims

1. A molded top having three openings for dispensing flowable particulate material from a container, the top comprising:

a web, the web being substantially planar;

an annular skirt depending from the web for attachment to the container;

a first opening in the web sized to accommodate an utensil, the first opening having a first closure integrally joined to the web by a first living hinge and configured to seal the first opening;

a second opening in the web having a second closure integrally joined to the web by a second living hinge to pivot between an opened and a closed position and the second closure including a pathway to direct the particulate material in exiting the container in the opened position and configured to seal the second opening when pivoted into the closed position; and

a third opening comprising a plurality of smaller sift openings in the web arranged in an array for sifting the particulate material from the container, and a third closure integrally joined to the web by a third living hinge and configured to seal each of the sift openings.

2. The dispensing top of claim 1, wherein the first, second and third closures are opened and closed independently of each other.

3. The dispensing top of claim 2, wherein the first closure includes a free edge that, along with the first living hinge, defines the outer boundary of the first closure, and an undersurface facing the first opening, and wherein the first closure flap has a sealing lip extending along the undersurface and spaced inwardly from the free edge, the sealing lip configured to fit tightly inside the first opening.

4. The dispensing top of claim 3, further comprising a depression portion disposed in the interior of the web partially disposed under the second closure.

5. The dispensing top of claim 4, wherein the second closure comprises an elongated member extending from the second living hinge and configured to overlie and seal the second opening when in the closed position, and a pair of sidewalls extending in parallel from opposing edges of the elongated member, each of the sidewalls having a boss extending from the sidewall in a direction away from the second living hinge to limit how far the elongated member can pivot in the open position, and a detent located along the periphery of the sidewall to provide a snap fit with the web when the second closure is in the closed position.

6. The dispensing top of claim 5, wherein the third closure includes an undersurface facing the third opening, and a plurality of plugs extending from the undersurface and the plugs arranged in an second array matching the array of the small openings, each of the plugs configured to fit tightly inside a corresponding opening.

7. The dispensing top of claim 6, wherein the web is substantially circular.

8. The dispensing top of claim 6, wherein the web is substantially rectangular.

9. The dispensing top of claim 8, wherein the area defined by the first opening is at least half as large as the area defined by the web.

10. The dispensing top of claim 7, wherein the first opening, the second opening, and the sift openings are radially disposed with respect to a center position about the periphery of the web.

11. A three port molded dispensing top, comprising:

a web, the web being substantially planar;

an annular skirt depending from the web for attachment to a container;

a first port having a first opening for spooning a particulate product from the container and a first closure integrally joined to the web by a first living hinge and configured to seal the first opening;

a second port having a second opening and a pivotable extended member for pouring the particulate product from the container, the extended member being integrally joined to the web by a second living hinge, and configured to lock the second opening when pivoted into a closed position;

a third port having a plurality of relatively small openings arranged in an array for sifting the particulate product from the container, and a second closure flap integrally joined to the web by a living hinge and configured to seal the openings; and

a depression portion within an interior portion of the web positioned underneath a portion of the extended member.

12. The dispensing top of claim 11, wherein, the extended member includes opposing parallel sidewalls extending therefrom to form a pathway for the particulate product to exit the container.

13. The dispensing top of claim 12, wherein at least one of the sidewalls includes a detent extending therefrom for locking the extended member into the closed position.

14. The dispensing top of claim 13, wherein at least one of the sidewalls includes a boss extending from the sidewalls in a direction away from the second living hinge so as to limit the travel of the extended member.

15. The dispensing top of claim 14, wherein the second closure includes an undersurface having a plurality of plugs extending therefrom and arranged in a second array matching the array of the relatively small openings, and each of the plugs configured to fit tightly inside a corresponding opening.

16. The dispensing top of claim 15, wherein the web includes a shoulder portion disposed around the periphery of the web for stacking a second container thereon.

17. The dispensing top of claim 16, wherein the second closure includes a top surface with a raised texture pattern matching the array for tactile designation.

18. The dispensing top of claim 17, wherein the depression portion includes a retaining area for the extended member.

19. The dispensing top of claim 18, wherein the depression portion is substantially hemispherical.

20. The dispensing top of claim 19, wherein the first opening, the second opening, and the sift openings are disposed about a plurality of radial axes with respect to a center position about the periphery of the web.
