Antiseptic soap dispenser with selectively variable dose

Abstract

An antiseptic soap dispenser has a dispensing system (,) which includes a pressure actuated platen (,) and a moveable roller (,) for dispensing soap from a replaceable container (,). A dispensing tube (,) with an integral self-sealing valve (,) at a downstream end is connected to a neck (,) 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 (,) 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 (,) in a wall (,) of the container allows filtered air to enter the container in place of the soap dispensed.
