ABSTRACT:
A closing cap (1) for two-chamber containers (2), which can be connected to an outlet opening (3) of the container (2). The container (2) is divided by a separating element (4), which extends up to outlet opening (3), so that the contents of the first chamber (5) are supplied separately from the contents of the second chamber (6) to the outlet opening (3). According to the invention, a detent connection is provided for joining the closing cap (1) to the container (2), whereby a separating wall (12) divides the closing cap (1) into two separate areas. A separately closeable withdrawal opening (8, 8′) is arranged in each area, and the separating wall (12) interacts with the separating element (4) as to connect each of the chambers (5,6) of the container (2) only to the area of the closing cap (1), in which the assigned withdrawal opening (8, 8′) is located.
