1. A device for dispensing fluids, the device comprising:
a control valve housing having a valve housing securing surface substantially surrounding the periphery of the control valve housing;
a staging reservoir having a staging reservoir securing surface substantially surrounding the periphery of the staging reservoir, wherein the staging reservoir securing surface cooperates with the valve housing securing surface to create a seal between the control valve housing and the staging reservoir and to define a common volume therebetween;
a coupler to secure the device to a primary reservoir, wherein the coupler defines a fluid flow path through which fluid may flow from the primary reservoir to the common volume through a fluid inlet when the coupler is attached to the primary reservoir;
a valve assembly comprising:
a control valve body having an inlet sealing surface configured to selectively seal off the fluid inlet; and
a biasing member configured to act on the control valve body to bias the inlet sealing surface toward the coupler to seal off the fluid inlet, preventing exchange of fluid between the device and the primary reservoir;
an actuator to move the control valve body away from the coupler against the action of the biasing member; and
an outlet for dispensing a fluid contained in the common volume;
wherein the seal between the securing surfaces of the control valve housing and staging reservoir is substantially circular, which circle defines a plane wherein the outlet and fluid inlet are on one side of the plane, and the majority of the common volume is on the other side of that plane.
