<p>A connection device (1) for containers (13) suitable for holding fluids, concentrates and the like which are engageable to a liquid pre- and post-mix dispensing apparatus and/or a source of fluid extracting assembly (10) are proposed wherein said connection device has a cavity housing internal valve means (5, 9, 15, 15', 15', 25, 26, 27, 28) for closing and opening controllable passages so as to simultaneously direct flows (Qu1, Qu2) of fluids of different viscosity (u1, u2) in opposite directions through said cavity when said connection device is coupled by an actuator device (2) thereby forming said fluid extracting assembly (10). As a result thereof stainless steel containers, plastic pockets suction pumps and the like in known liquid dispensing systems are replaced by disposable containers for storing and delivering concentrates within a fluid dispensing system when coupled by the fluid extracting assembly (10).</p> |
