This invention teaches dispensing a precise amount of liquid from a rigid vessel using a combination of valves, plugs, and diaphragms. In particular, a rigid container with a connected measuring receptacle can dispense oil. A user can depress at least one diaphragm on the rigid container to pressurize a chamber, forcing the liquid upwards into a hollow tube and into the measuring receptacle. The hollow tube, traversing the interior of the container, has at least one orifice at both the proximal and distal ends. The user can calibrate the amount of liquid in the measuring receptacle by activating a release valve or stopper to remove the liquid from the measuring receptacle and back into the container. In addition, a flexible and optionally removable lid covers the measuring receptacle. This lid can be depressed to pressurize the measuring receptacle and expel the liquid from an orifice on the measuring receptacle.
A device capable of dispensing a precise amount of liquid, wherein the device is comprised of a top, a middle, and a bottom chamber, the middle chamber being at least single walled, the top chamber and the middle chamber connected together by a first gasket in a static seal, and the middle chamber and the bottom chamber connected together by a second gasket in a static seal, at least one first valve in between the bottom and middle chambers, the at least one first valve allowing air pressure from the middle chamber to enter the bottom chamber to forcibly displace the liquid in the bottom chamber up into a hollow tube, each chamber having a cavity capable of containing the liquid, the hollow tube traversing the vertical length of the device's interior, the hollow tube having a distal end that terminates in the top chamber and a proximal end that terminates in the bottom chamber, the distal and proximal ends each having at least one orifice, the top chamber having a side orifice capable of allowing the liquid to exit the top chamber, the middle chamber having a least one flexible portion that is capable of being depressed to increase the air pressure in the middle chamber, the at least one flexible portion having at least one orifice, an actuator connected to a stopper that plugs a hole between the middle and bottom chambers that when activated removed the stopped between the middle and bottom chambers and allows air pressure from the bottom chamber to exit the bottom chamber and re-enter the middle chamber.
