Abstract

A dispensing closure system includes an upper closure portion and a lower closure portion including an axial flow conduit and a vent conduit. The upper closure portion is axially movable relative to lower closure portion between shipping and dispensing positions. A seal is disposed on the lower closure portion over the flow and vent conduits. A peripheral spacing strip is removably secured to the upper closure portion and engages with either the lower closure or the outside of the container to prevent movement. A piercing probe includes piercing elements in alignment with the flow and vent conduits for piercing the seal. In the shipping position, the piercing elements are spaced from the seal. However, when the spacing strip is removed and the upper closure portion is axially moved to the dispensing position, the piercing elements pierce the seal to open the flow conduit and the vent conduit.

First claim

What is claimed is:

1. A dispensing system, comprising:
a container;
a closure attached to the container, the closure comprising:
an upper surface;
a skirt, comprising:
inward threading on an interior of the skirt; and
outward threading on an exterior of the skirt;

an axial flow conduit; and
a dip tube port;

a dip tube attached to the dip tube port and extending into the container; and
a seal disposed on said upper surface over the axial flow conduit.

2. The dispensing system of claim 1 , wherein the container further comprises a threaded neck portion.

3. The dispensing system of claim 2 , wherein the inward threading of the skirt engages the threaded neck portion of the container.

4. The dispensing system of claim 1 , wherein the closure further comprises a venting passage.

5. The dispensing system of claim 1 , wherein the seal comprises a foil seal.

6. The dispensing system of claim 1 , wherein the seal is made of a material capable of being pierced.

7. The dispensing system of claim 1 , further comprising a dispenser attached to the outward threading of the skirt.

8. A dispensing system, comprising:
a container;
a closure, comprising:
a top deck;
an outer skirt extending axially away from an edge of the top deck, the outer skirt having an interior skirt surface and an exterior skirt surface;
inward threading on the interior skirt surface;
outward threading on the exterior skirt surface;

an axial flow conduit interior of the outer skirt, extending axially away from the top deck into a space formed by the outer skirt; and
a seal disposed on said top deck over the axial flow conduit.

9. The dispensing system of claim 8 , wherein the closure is connected to the container.

10. The dispensing system of claim 8 , wherein the container further comprises a neck portion with threading and the inward threading on the interior skirt surface engages the threading of the container neck portion to retain the closure on the container.

11. The dispensing system of claim 8 , further comprising a liquid product in the container.

12. The dispensing system of claim 8 , further comprising a dip tube connected to the axial flow conduit.

13. The dispensing system of claim 8 , wherein the closure further comprises a vent path.

14. The dispensing system of claim 8 , further comprising a pump attached to the closure.

15. A closure, comprising:
a top deck;
an outer skirt extending axially away from an edge of the top deck, the outer skirt having an interior skirt surface and an exterior skirt surface;
inward threading on the interior skirt surface;
outward threading on the exterior skirt surface;
an axial flow conduit interior of the outer skirt, extending axially away from the top deck into a space formed by the outer skirt;
a dip tube connected to the axial flow conduit; and
a seal disposed on said top deck over the axial flow conduit.

16. The closure of claim 15 , wherein the inward threading is configured to engage complementary threading on a container neck.

17. The closure of claim 15 , wherein the outward threading is configured to engage complementary threading on a dispenser.

18. The closure of claim 15 , wherein the seal is a foil seal.

19. The closure of claim 15 , wherein the seal is made of a material that may be pierced.

20. The closure of claim 15 , further comprising a vent path.
