Abstract
A closure device for addition of a liquid substance separately packaged therein into an associated container containing a gas release liquid includes a connector sleeve and a twist cap fitting thereon. The connector sleeve holds a cup inside with the cup bottom extending into the container connector. The cup includes therein a substance container containing the liquid substance, disposed above a piercing and cutting mechanism having upwardly directed cutting tips and a downward arbor, and the cup has an opening at the bottom closed by the arbor. When the twist cap is rotated in the loosening direction, the piercing and cutting mechanism is moved upward, causing piercing of the substance container, and exposing the opening thereby pressure compensation occurs between the cup and container. Further loosening of twist cap causes pressure drop in the container, and the liquid substance is injected through the opening of the cup into the container.
