| 1. A method of dispensing a fluid from a container, the method comprising the steps of:
a. providing a container having a container closure assembly associated therewith, wherein the container closure assembly
includes a cap and a spout, wherein the interior of the spout is spanned by a sealed membrane that includes a plurality of
score lines defined therein, wherein the cap includes a puncturing mechanism that extends downwardly from the top thereof,
b. moving the cap downwardly,
c. puncturing the membrane with the puncturing mechanism to break the score lines, thereby forming a plurality of flaps that
define an opening,
d. removing the cap from the spout, wherein after the cap is removed the material of the membrane causes the membrane to approximately
retain its shape from before the membrane was punctured to restrict fluid flow through the opening, and
e. dispensing the fluid through the opening.
