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.
