A liquid dispensing device includes a container removably mounted to a tray such that an orifice in the base of the container is below a fill line of the tray. A flat-shaped cap that includes an opening is removably attached to the orifice. A cap adjustment member forces the cap into a concave shape when the container is removably mounted to the tray. If the cap is in the flat shape, surface tension of the liquid in the container prevents the container from dispensing liquid. However, forcing the cap into the concave shape disrupts the surface tension of the liquid and allows the container to dispense the liquid if the liquid is not already above a fill line. These features allow the orifice to be wide enough for cleaning while the cap is narrow enough for operation without the cap causing surface tension that hinders operation.

1. A liquid dispensing device for animals, comprising: a tray comprising a basin;a container, operable to store a quantity of liquid, comprising a base including an orifice and a top connected to the base by at least one side wall, the container removably mounted to the tray such that the container
1. A liquid dispensing device for animals, comprising: a tray comprising a basin;a container, operable to store a quantity of liquid, comprising a base including an orifice and a top connected to the base by at least one side wall, the container removably mounted to the tray such that the container extends upwardly from tray and the orifice is within the basin;a cap coupled to the container, partially blocking the orifice, the cap including an opening; anda cap adjustment member operable to force at least a portion of the cap into a concave shape away from the tray;wherein the container is operable to dispense the liquid into the basin when the at least a portion of the cap is in the concave shape and a liquid level of the basin is below a fill line and the container is not operable to dispense the liquid into the basin when at least one of the at least a portion of the cap is not in the concave shape or the liquid level of the basin is not below the fill line. 2. The liquid dispensing device of claim 1, wherein the tray includes the cap adjustment member and the cap adjustment member is operable to exert pressure upon the cap to force the at least a portion of the cap into the concave shape when the container is mounted to the tray. 3. The liquid dispensing device of claim 1, wherein the cap includes the cap adjustment member and the cap adjustment member is operable to exert pressure upon the tray to force the at least a portion of the cap into the concave shape when the container is mounted to the tray. 4. The liquid dispensing device of claim 1, wherein a diameter of the orifice is sufficiently wide that if the cap is not coupled to the container the container dispenses the liquid into the basin regardless whether the liquid level of the basin is below the fill line. 5. The liquid dispensing device of claim 1, wherein a diameter of the opening is sufficiently narrow that if the cap is not in the concave shape surface tension prevents the container from dispensing the liquid into the basin even if the liquid level of the basin is below the fill line. 6. The liquid dispensing device of claim 1, wherein the cap is in a flat shape when the cap adjustment member does not exert pressure on the cap. 7. The liquid dispensing device of claim 6, wherein the cap is removably coupled to the container. 8. An apparatus for automatically dispensing liquid, comprising: a tray;a container comprising a base including an orifice, the container removably mounted to the tray such that the container extends upwardly from tray and the orifice is within the tray;a cap removably coupled to the container over the orifice, the cap including an opening that has a diameter that is narrower than a diameter of the orifice; anda cap adjustment member operable to force at least a portion of the cap into a concave shape away from the tray;wherein the container is operable to dispense liquid stored in the container into the tray when the at least a portion of the cap is in the concave shape and a liquid level of the basin is below a fill line and the container is not operable to dispense the liquid into the tray when the liquid level of the tray is not below the fill line. 9. The apparatus of claim 8, wherein the cap comprises a flexible material. 10. The apparatus of claim 8, wherein the container is not operable to dispense the liquid into the basin when the at least a portion of the cap is not in the concave shape. 11. The apparatus of claim 10, wherein the container is not operable to dispense the liquid into the basin when the at least a portion of the cap is not in the concave shape because of surface tension of the liquid. 12. The apparatus of claim 8, wherein the container is operable to dispense liquid stored in the container into the tray when the liquid level of the basin is below the fill line and the at least a portion of the cap is in the concave shape because the at least a portion of the cap that is in the concave shape disrupts surface tension of the liquid. 13. The apparatus of claim 8, wherein the cap adjustment member comprises a protrusion extending upward from a surface of the tray toward the cap. 14. The apparatus of claim 8, wherein the cap adjustment member comprises a protrusion extending downward from a surface of the cap toward the tray. 15. A system for automatically dispensing liquid, comprising: a basin;a reservoir comprising a base including an orifice and a top connected to the base by at least one side wall, the reservoir extending upwardly from the basin such that the orifice is within the basin;a cap removably coupled to the reservoir, operable to partially block the orifice, the cap including an opening that has a diameter that is narrower than a diameter of the orifice, the cap comprising a more flexible material than the basin and the reservoir; anda cap adjustment member operable to force at least a portion of the cap into a concave shape away from the tray;wherein the reservoir is operable to dispense liquid stored in the reservoir into the basin when the at least a portion of the cap is in the concave shape and a liquid level of the basin is below a fill line, pressure inside the reservoir prevents the reservoir from dispensing liquid into the basin when the liquid level of the basin is not below the fill line, and surface tension of liquid prevents the reservoir from dispensing liquid into the basin when the at least a portion of the cap is not in the concave shape. 16. The system of claim 15, wherein the cap adjustment member forcing the at least a portion of the cap into the concave shape disrupts the surface tension of the liquid. 17. The system of claim 15, wherein the cap adjustment member comprises a protrusion extending upward from a surface of the basin toward the cap and the cap adjustment member is operable to exert pressure to force the at least a portion of the cap into the concave shape when the reservoir is mounted to the basin. 18. The system of claim 15, wherein the cap adjustment member comprises a protrusion extending downward from a surface of the cap toward the basin and the cap adjustment member is operable to exert pressure to force the at least a portion of the cap into the concave shape when the reservoir is mounted to the basin. 19. The system of claim 15, wherein the fill line is below a top of the basin. 20. The system of claim 15, wherein the orifice is the only opening in the reservoir.
