A double-dispenser system for dispensing medicinal liquids has two jet-trigger pumps housed in an outer casing having at least one front opening and one rear opening. Each jet-trigger pump is provided with a dosing mechanism for dispensing a predetermined dose of medicinal liquid. Dispensation from the two pumps may be triggered simultaneously by a trigger device common to the two pumps and accessible from the outside of the casing. The pumps incorporated in the double-dispenser system may be of the type having a pump body and a piston housed in an elastic bottle. For each pump, relative movements between the piston and the pump body causes changes in the relative-displacement between the piston and the pump body such that medicinal liquid is initially loaded into a medicine-holding cavity within the pump and subsequently dispensed.
