Abstract
A fluid device generally comprises a staging reservoir which may receive a volume of fluid flowing from a primary reservoir via a coupler upon operation of an actuator, wherein the staging reservoir is usable to measure fluid within the device in order to dispense a desired amount of fluid.
Claims18
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.

A metering device for measuring and dispensing fluid from a primary reservoir, the device comprising:
- a valve housing having a coupler configured to releasably connect to the primary reservoir;
- a staging reservoir in fluid communication with the coupler, the staging reservoir defining a primary volume for receiving the fluid from the coupler;
- a control valve disposed between the coupler and the staging reservoir, the control valve operable between an open position that allows fluid to flow between the coupler and the primary volume, and a closed position to prevent fluid from flowing between the coupler and the primary volume;
- and
- a fluid outlet on said valve housing for dispensing a volume of fluid from the primary volume;
- wherein the valve housing and the staging reservoir are removably connected at respective mating sealing surfaces that, when brought together, form a seal that defines a plane, and wherein the coupler and fluid output are on one side of the plane, and at least the majority of the primary volume is on the other side of that plane;
- wherein the control valve is biased toward the closed position;
- wherein the device is rotatable from a storage position where fluid within the primary reservoir is below the coupler, to a staging position where fluid within the primary reservoir is at least partially above the coupler, and a dispensing position where the fluid within the primary volume is above the fluid outlet;
- and
- whereby to allow a desired amount of fluid to be dispensed from the primary reservoir to the primary volume, the device is rotated from a storage position to a staging position where fluid is blocked, the control valve is moved to an open position, and is further rotatable to a dispensing orientation different from the staging orientation to dispense desired amount of fluid from the staging reservoir through the staging reservoir outlet.
