CONTAINER CLOSURE ASSEMBLIES

摘要

The present invention relates to double compartment closure assemblies in which materials are stored in at least two separate 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 inadvertent 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.
