The fluid dispensing system includes a container formed by a first chamber and a second chamber separated by an internal divider. A stopper element extends through each chamber via a first aperture disposed in the internal divider. A second aperture is disposed in a base of the second chamber, wherein the stopper element is used to selectively allow fluid to flow from the first chamber into the second chamber when the stopper element is in a measuring configuration. When the stopper element is in a dispensing configuration, the first aperture between is closed and the second aperture is opened to allow fluid from the second chamber to flow exterior from the container. In this manner, a measured amount of fluid from the container can be dispensed in a single movement without using a secondary measuring receptacle. ## Claims ### Claim 1 A fluid dispensing system, comprising: a container having a first chamber and a second chamber, wherein both the first chamber and the second chamber are configured to hold a fluid therein; an internal divider separating the first chamber from the second chamber; a first aperture disposed within the internal divider that allows the fluid to flow from the first chamber to the second chamber; a second aperture disposed in the second chamber that allows the fluid to dispense from the second chamber to an exterior of the container; a stopper element comprising a shaft having a release knob at a first end and a plug at a second end, wherein the release knob extends exterior to the container and is adapted to move the stopper element between a measuring configuration and a dispensing configuration; wherein the measuring configuration, the second aperture is sealed via the plug and unsealing the first aperture such that the fluid can freely pass from the first chamber to the second chamber; wherein the dispensing configuration, the first aperture is sealed via the plug and unsealing the second aperture such that fluid can freely pass from the second chamber to the exterior of the container. ### Claim 2 (depends on 1) The fluid dispensing system of claim 1, wherein the internal divider is disposed along a horizontal plane that is parallel to a lowermost side of the container and the stopper element moves along a vertical axis of the container. ### Claim 3 (depends on 2) The fluid dispensing system of claim 2, wherein the first chamber is disposed above the second chamber is a stacked configuration. ### Claim 4 (depends on 3) The fluid dispensing system of claim 3, wherein a sidewall of the first chamber and the second chamber is continuous and coextensive with one another. ### Claim 5 (depends on 1) The fluid dispensing system of claim 1, wherein the internal divider is secured to a sidewall of the container and to a lowermost surface of the container, such that the second chamber is disposed on a side of the container. ### Claim 6 (depends on 5) The fluid dispensing system of claim 5, wherein the stopper element moves along a horizontal axis of the container. ### Claim 7 (depends on 1) The fluid dispensing system of claim 1, wherein the shaft comprises a smaller diameter than the plug, such that in the measuring configuration the shaft extends through the first aperture forming a gap from which the fluid passes through to the second chamber. ### Claim 8 (depends on 1) The fluid dispensing system of claim 1, wherein the first end of the stopper element comprises a release knob disposed exterior to the container and configured to linearly move the shaft. ### Claim 9 (depends on 1) The fluid dispensing system of claim 1, wherein the first end of the stopper element comprises a first gasket seal and a first seat adapted to seal an upper opening of the container, wherein the fluid received through the upper opening is received directly into the first chamber. ### Claim 10 (depends on 9) The fluid dispensing system of claim 9, wherein the stopper element comprises a first shaft section disposed between the first gasket seal and the release knob, wherein the first shaft section is telescopic such that the release knob is configured to secure to a mouth of the container while the upper opening remains sealed by the first gasket seal. ### Claim 11 (depends on 1) The fluid dispensing system of claim 1, wherein the second end of the stopper element comprises a second gasket seal, a third gasket seal, and a seat therebetween wherein the second gasket seal is configured to seal the first aperture, the third gasket seal is configured to seal the second aperture, and the seat is configured to prevent the second and third gasket seals from passing through the first and second aperture. ### Claim 12 (depends on 11) The fluid dispensing system of claim 11, wherein a second shaft section extends between the second gasket seal and the third gasket seal. ### Claim 13 (depends on 11) The fluid dispensing system of claim 11, wherein the third gasket seal forms a lower most end of the stopper element. ### Claim 14 (depends on 1) The fluid dispensing system of claim 1, wherein the second chamber comprises a smaller interior volume than the first chamber and the smaller interior volume comprises a predetermined volume measurement. ### Claim 15 (depends on 1) The fluid dispensing system of claim 1, further comprising a measuring plate disposed within the second chamber and operably connected to a plate knob extending from a sidewall of the container, wherein the measuring plate is movable via the plate knob and configured to prevent fluid from passing from a lower end of the second chamber to an upper end of the second chamber. ### Claim 16 (depends on 15) The fluid dispensing system of claim 15, further comprising indicia on the container indicating a volumetric measurement, wherein the measuring plate is adapted to align therewith. ### Claim 17 (depends on 1) The fluid dispensing system of claim 1, wherein the first and second aperture are in vertical alignment with the vertical axis. ### Claim 18 A fluid dispensing system, comprising: a container having a first chamber and a second chamber, wherein both the first chamber and the second chamber are configured to hold a fluid therein; a plurality of holes is disposed within a lower end of the second chamber that allows the fluid to flow from the first chamber to the second chamber; a second aperture disposed in the second chamber that allows the fluid to dispense from the second chamber to an exterior of the container; a stopper element comprising a shaft having a release knob at a first end and a plug at a second end, wherein the release knob extends exterior to the container and is adapted to move the stopper element between a measuring configuration and a dispensing configuration; wherein the measuring configuration the second aperture is sealed by the plug and the plurality of holes is unsealed; wherein the dispensing configuration the second aperture is unsealed to allow fluid to flow from the second chamber to the exterior of the container and the plurality of holes are sealed by the plug. ### Claim 19 (depends on 18) The fluid dispensing system of claim 18, further comprising: a measuring plate disposed around the shaft of the stopper element and configured to prevent fluid from flowing to an opposing side of the measuring plate; a measuring guide secured to the measuring plate, wherein the measuring guide is configured to slide the measuring plate along the shaft to adjust a volume of fluid that can be received within the second chamber in the measuring configuration. ### Claim 20 (depends on 18) The fluid dispensing system of claim 18, wherein the second chamber extends from a base of the container to an open upper end of the container.
