Abstract
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.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
206 words
A double container for two fluids, comprising an outer container defining an interior and accomodating a first fluid; an inner container located in the interior of the outer container and accomodating a second fluid; an outlet nozzle being selectively in communication with the inner and outer containers; and means for selectively locking the access from the inner and outer containers to the outlet nozzle and including an inner locking part aranged on the outer container and being connected to the inner container, and an outer locking part connected to the outlet nozzle and pivotally arranged on the inner locking part which accommodates at least one opening communicating with the outer container and at least one further opening communicating with the inner container, so that upon rotation of the outer locking part with respect to the inner locking part, the first and second fluid are selectively discharged through the associated opening, said outer locking part being provided with at least one blocking member for selectively sealing off said at least one opening and said at least one further opening, said inner locking part being provided with a prolongation projecting into the interior of the outer container and connected to the inner container, said prolongation accommodating the openings.
Claim 2
Dependent Claim
