An antiseptic soap dispenser has a dispensing system (28) which includes a pressure actuated platen (32) and a moveable roller (94) for dispensing soap from a replaceable container (12). A dispensing tube (10) with an integral self-sealing valve (40) at a downstream end is connected to a neck (20) of the container. Hand pressure on the platen compresses a upstream end of the dispensing tube between the platen and the roller. With increasing pressure, the roller moves progressively down the tube to dispense soap through the valve. A volume regulator (111) controls the amount of soap dispensed. The platen returns quickly to its at-rest position once the pressure is removed, avoiding complete compression of the pathway by the roller. This minimizes air ingress, and resultant contamination of the soap. Optionally, a filtered vent (14) in a wall (22) of the container allows filtered air to enter the container in place of the soap dispensed.

[ Having thus described the preferred embodiment, the invention is now claimed to be:] [1.] A dispenser for discharging a liquid comprising:a housing including a front cover and a back plate;a reservoir for containing the liquid, the reservoir removably mounted within the housing, the reservoir including:a container, anda flexible tube connected at an upstream end to the container, a valve selectively closing a downstream end of the tube;a roller assembly pivotally mounted in the housing, the roller assembly including a roller bar, rotatably mounted on an assembly body;a platen moveably connected to the front cover of the housing such that pressure on the platen moves the platen towards the roller assembly, the platen compressing the upstream end of the tube between the platen and the roller bar and camming the roller bar towards the downstream end of the tube.
