Closure device for a container

Abstract

A closure device for a container opening includes a lid element for closing the container opening, a chamber associated with the lid element, and an inner housing, the chamber and the inner housing also having mutually corresponding closure means and opening means which are in interaction with each other such that a discharge opening associated with the chamber as opening means can be released by rotationally moving the closure means connected to the lid element relative to the inner housing such that a medium stored in the chamber can exit into the container. The closure means is a closure pin which is fixedly connected to the chamber and which comprises a vertical extension provided with respect to a rotational axis and that the closure means are formed in the vertical extension, with different areas: a flow-through area and a closure area.
