Closure device for a container

A closure device (1) for a container (2) with a container opening (10), comprising;

• a lid element (3) configured for closing the container opening (10), a chamber (4) assigned to the lid element (3) and an inner housing (5), wherein the chamber (4) and the inner housing (5) have closing and opening elements that correspond to one another and interact with one another in such a way that a medium contained in the chamber (4) can exit into the container (2) due to a movement of the lid element (3) relative to the inner housing (5), wherein the chamber (4) has a freely projecting closure edge, which in a usage state is directed into a container interior, circumferentially extends around a central axis of the chamber (4) in an annular manner and in the closed state interacts with the inner housing (5) in a closing manner, wherein the inner housing (5) forms a chamber bottom (14) that is delimited by the closure edge, wherein the chamber bottom (14) forms a channel (15) that extends around an entire circumference of the chamber bottom and which is delimited by a radially inner channel side wall (16), a radially outer channel side wall (17) and a channel bottom (18), wherein the chamber (4) forms a discharge nozzle (11) having an annular end region that is permanently seated in a sealing element (22) disposed in the channel (15) so as to be not displaceable in a vertical direction (x), wherein the chamber (4) is interlocked with the inner housing (5), and wherein the interlock (6) with the inner housing (5) is with respect to a vertical central axis (x) of the closure device (1) offset radially inward in relation to a greatest inner width (k) of the chamber (4) in an offset direction (L), wherein the interlock (6) is in the vertical direction (M) designed separately from a shoulder section (40) of the inner housing (5), which is formed on the bottom side underneath the interlock (6) and functionally connected to the container opening (10).
