Patent

CA 2121695

The present invention relates to double compartment closure assemblies in which materials are stored in at least two sepa- rate compartments until the compartments are opened for use. The multiple compartment container assembly includes at least two adjacent compartments (17, 19), each having a nozzle aligned at their discharge end (22, 23), and including a thin wall (25, 33) dispensing port for discharge of the contents from the compartments by use of a bellows arrangement (37, 39) formed from the compartments. A cap (11) is sized to moveably fit on the discharge end of the container and includes a puncture device (27. 31) positioned in alignment with the thin wall dispensing ports. The cap may be positioned at a first position to prevent inadvert ent movement of the cap, and to permit intentional movement of the cap to a second position to cause the puncture device to puncture the ports.
