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 closure system, comprising:
an upper closure portion comprising an outer skirt;
a tear away spacing strip connected to a lower portion of the outer skirt; and
a lower closure portion, comprising:
an upper surface;
a plurality of recessed in the upper surface
an axial flow conduit; and
a plurality of vent conduits in the plurality of recesses; and
a seal disposed over the upper surface.

2. The dispensing closure system of claim 1 , further comprising a container attached to the upper closure portion, comprising a shoulder portion, wherein the tear away strip engages the shoulder portion of the container.

3. The dispensing closure system of claim 1 , wherein the plurality of vent conduits concentrically surround the axial flow conduit.

4. The dispensing closure system of claim 1 , wherein the axial flow conduit defines an opening in the upper surface.

5. The dispensing closure system of claim 1 , wherein the plurality of vent conduits define openings in the upper surface.

6. The dispensing closure system of claim 1 , further comprising a piercing probe.

7. The dispensing closure system of claim 1 , further comprising a piercing probe seated in the upper closure portion, comprising:
a central axial piercing element; and
aligned concentric elements.

8. The dispensing closure system of claim 7 , wherein removal of the tear away spacing strip allows rotational movement of the upper closure portion and movement of the piercing probe to pierce the seal and align the central axial piercing element with the axial flow conduit and the aligned concentric elements with the plurality of recesses.

9. The dispensing closure system of claim 1 , further comprising a dispensing head attached to the upper closure portion.

10. The dispensing closure system of claim 9 , wherein the dispensing head is a spray dispensing head.

11. The dispensing closure system of claim 9 , wherein the dispensing head is a pump-style dispensing head.

12. A dispensing closure system mounted on a container, comprising:
an upper closure portion comprising a threaded outer skirt engaged with a threaded neck of the container;
a dispensing head comprising a throat portion received in the upper closure portion;
a tear away spacing strip connected to a lower portion of the threaded outer skirt and in contact with a shoulder portion of the container;
a lower closure portion seated within the neck of the container, comprising:
an upper surface;
an axial flow conduit; and
a plurality of vent conduits;

a seal over the upper surface; and
a piercing probe seated in the upper closure portion between the dispensing head and the seal.

13. The dispensing closure system mounted on a container of claim 12 , wherein removal of the tear away spacing strip allows rotational movement of the upper closure portion.

14. The dispensing closure system mounted on a container of claim 13 , wherein rotational movement of the upper closure portion moves the piercing probe towards the seal and pierces the seal.

15. The dispensing closure system mounted on a container of claim 12 , wherein the piercing probe further comprises:
a central axial piercing element; and
aligned concentric elements.

16. The dispensing closure system mounted on a container of claim 15 , wherein movement of the piercing probe aligns the central axial piercing element with the axial flow conduit and the aligned concentric elements with the plurality of vent conduits.

17. The dispensing closure system mounted on a container of claim 12 , wherein the dispensing head is selected from the group consisting of a spray dispensing head and a pump-style dispensing head.
