Abstract
A motion-activated dispenser includes a housing having a base and top defining a gap sized to receive a human hand. The top portion defining cavity sized to receive a fluid reservoir and an opening extending directly through a lower surface of the top portion to the cavity, a neck of the fluid reservoir extending through the opening. A pressing member is positioned within the cavity and an actuator is coupled to the pressing member and configured to urge the pressing member toward and away from the opening. The pressing member may include, for example, a sliding member positioned opposite a stop face; a roller moved by the actuator toward the opening; a plunger positioned above the opening and driven by an actuator toward the opening; or a pair of rods spanning the cavity and urged by the actuator through the cavity, the rods pressing against sides of the reservoir.
