A container for storing two components separately and then mixing them prior to use includes a housing having an opening and a neck portion, a displaceable member, and a closure member. The housing is formed with a first compartment and a second compartment intercommunicating at the neck portion. The displaceable member has a partition wall for sealing the neck portion. The displaceable member is formed such that the partition wall moves from a non-sealing position in which the first and second compartments intercommunicate to a sealing position in which the neck portion is sealed. The displaceable member also may feature at least one conduit for allowing introduction of a component through the opening into the housing. The closure member seals the at least one conduit of the displaceable member and/or the opening of the housing. The displaceable member may be moved by rotating, pushing or pulling and may be moveable by a portion exterior to the housing. The seal formed by the partition wall of the displaceable member may be reformable, i.e., capable of being resealed. A pre-packaged, single use, two compartment container according to some embodiments of the invention have an unremovable closure member, an unreformable seal, an unfastenable closure member after it has been removed or is constructed in a manner or of materials which allow only a single use. The two-compartment container may also include a dosing assembly for dispensing a predetermined quantity of mixed formulation.

[ We claim:] [1.] A two-compartment container for separately storing two components, mixing the components and dispensing a formulation formed by mixing the two components comprising:(a) a housing having an opening at each of its top and bottom ends and a neck portion located between the top and bottom ends dividing the housing into top and bottom sections;(b) a top sealing member communicating with the top end opening of the housing for sealing the top end opening of the container;(c) a displaceable member having a partition wall at a first end which is configured and adapted to form a seal when it engages the neck portion, a manipulable portion adapted and configured to be controlled by a user to move the displaceable member, and at least one connecting member extending between the partition wall and the manipulable portion; and(d) a closure member sealing the bottom end opening;wherein the displaceable member is movable between a first position where the partition wall is located within a neck portion forming a seal and a common wall which divides the housing into two separate fluid-tight compartments and a second position where the partition is removed from the neck portion so that the two sections can intercommunicate.
