摘要

The present invention comprises a cap (101) having a chamber and a packaging unit having this cap (101) attached to a container. A membrane (405) separates the chamber in the cap from a reservoir in the container, so that two different components may be kept separate until ready to use. The cap (101) has a collapsible (102) button with a piercing element so that when the button (102) is pressed the membrane (405) is pierced and the contents of the chamber and reservoir may be mixed together.
