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. ## Claims ### Claim 1 A container and closure system, comprising: a container comprising a neck portion; a closure mounted to the neck portion of the container, the closure comprising: a top deck; an outer skirt extending axially away from an edge of said top deck; an annular recess interior of the outer skirt extending axially from the top deck into the neck portion of the container; a vent conduit interior of the annular recess; an axial flow conduit interior of the vent conduit and extending axially from the top deck into the neck portion of the container; and a seal disposed on an upper surface of the closure; and a clip tube connected to the axial flow conduit and extending into the container. ### Claim 2 (depends on 1) The container and closure system of claim 1, wherein the outer skirt is threadedly received with the container neck portion. ### Claim 3 (depends on 1) The container and closure system of claim 1, wherein the outer skirt is mounted to the container neck portion by a bayonet connection. ### Claim 4 (depends on 1) The container and closure system of claim 1, further comprising a gasket positioned between the closure and the container. ### Claim 5 (depends on 1) The container and closure system of claim 1, wherein the annular recess further comprises at least one thread. ### Claim 6 (depends on 1) The container and closure system of claim 1, wherein the annular recess further comprises a snap lock feature. ### Claim 7 (depends on 1) The container and closure system of claim 1, wherein the axial flow conduit further comprises a dip tube port on an end of the axial flow conduit within the container and wherein the clip tube is connected to the clip tube port. ### Claim 8 (depends on 1) The container and closure system of claim 1, wherein the seal is disposed over the flow conduit. ### Claim 9 (depends on 1) The container and closure system of claim 1, wherein the seal is disposed over the flow conduit and the vent conduit. ### Claim 10 (depends on 1) The container and closure system of claim 1, wherein the seal is a foil seal. ### Claim 11 (depends on 1) The container and closure system of claim 1, wherein the seal further comprises a seal made of a material that may be pierced. ### Claim 12 (depends on 1) The container and closure system of claim 1, further comprising a liquid product contained in the container. ### Claim 13 A dispensing system, comprising: a container comprising a neck portion; a closure mounted to the neck portion of the container, the closure comprising: a top deck; an outer skirt extending axially away from an edge of said top deck; an annular recess interior of the outer skirt extending axially from the top deck into the neck portion of the container; a vent conduit interior of the annular recess; an axial flow conduit interior of the vent conduit and extending axially from the top deck into the neck portion of the container; and a seal disposed on an upper surface of the closure; a clip tube connected to the axial flow conduit and extending into the container; and a dispenser connected to the closure. ### Claim 14 (depends on 13) The dispensing system of claim 13, wherein the dispenser further comprises a spray-type trigger dispenser. ### Claim 15 (depends on 13) The dispensing system of claim 13, wherein the dispenser further comprises a pump dispenser. ### Claim 16 (depends on 13) The dispensing system of claim 13, wherein the dispenser further comprises: a dispensing head; a piercing probe; and an upper closure. ### Claim 17 (depends on 16) The dispensing system of claim 16, wherein the upper closure further comprises: an annular neck portion; and a removable peripheral spacing strip; wherein the annular neck portion is attached to the closure. ### Claim 18 (depends on 17) The dispensing system of claim 17, wherein the annular neck portion of the upper closure is threadedly attached to the annular recess of the closure. ### Claim 19 (depends on 17) The dispensing system of claim 17, wherein the annular neck portion of the upper closure is snap attached to the annular recess of the closure.
