Abstract
A dispenser unit comprises a housing and an actuator movable relative to the housing to cause the contents of two containers to be dispensed simultaneously in mixed or separate state. Each container includes a hollow stem through which the substance is dispensed when the stem is depressed. The dispenser unit includes a fluid-conducting member distinct from the actuator and including two hoods for engaging the two stems of the containers. Depressing the actuator causes the fluid-conducting member to actuate the stems and initiate dispensing of the contents into a single passage or two separate passages of the fluid-conducting member. The fluid-conducting member is movable within the housing for accommodating mismatch in heights of the stems. The actuator includes a single internal channel or two separate channels for receiving the container contents from the fluid-conducting member.
