ABSTRACT:
A dual compartment pump dispenser is provided which includes a first and second container with a pair of independent pump mechanisms each for emptying product through a respective dispensing nozzle. The dispensing nozzles have openings oriented in a direction at least 60.degree. apart from one another, preferably 180.degree. apart. Different compositions are intended to be stored in each container for sequential rather than simultaneous use. The containers are joined along a sinusoidal curvilinear surface having complementary mating elongated recesses and ridges. A collar and base cup fasten the containers together.
