    Abstract: A double container consisting of elastic plastic material has an inner container and an outer container as well as a turning lock which includes an outer locking part and an inner locking part. The inner container is arranged within the outer container whereby the inner locking part of the turning lock is screwed to both containers. The outer locking part is connected with the inner locking part via a snap connection and is pivotally arranged thereon. The inner locking part is provided with outlet openings which are selectively closeable by blocking members at the lower end of the outlet nozzle which is connected to the outer locking part. Upon manual pressing of the outer container, the fluid contained in the inner container or the fluid contained in the outer container can be discharged. Also a mixing of both fluids is possible during the emptying when the outlet openings are only partly closed.
