A vehicle reservoir tank has an anti-spill chamber and an overflow channel. The anti-spill chamber has a body portion, an inlet at one end of the body portion and an outlet at another end of body portion. The anti-spill chamber is configured and arranged to restrict fluid flowing from a main reservoir chamber. The overflow channel has a first end portion, a second end portion and an intermediate curved portion. The first end portion is fluidly coupled to the outlet of the anti-spill chamber. The intermediate curved portion extends from the first end portion to the second end portion such that the second end portion of the overflow channel extends downwardly relative to the first end portion. The second end portion extends along an area of the body portion of the anti-spill chamber to restrict the flow from the anti-spill chamber.

What is claimed is: 1. A vehicle reservoir tank comprising: a main reservoir chamber having a fluid drain port and an overflow port disposed at an upper portion of the main reservoir chamber; an anti-spill chamber having a body portion, an inlet disposed at a lowermost section of the body portion and an outlet disposed exclusively above the inlet at an uppermost section of the body portion with the inlet being externally coupled to the overflow port of the main reservoir chamber, the anti-spill chamber being configured and arranged to restrict fluid flowing from the main reservoir chamber; an overflow channel having a first end portion fluidly coupled to the outlet of the anti-spill chamber at the uppermost section of the body portion, and an intermediate curved portion extending from the first end portion to a second end portion such that the second end portion of the overflow channel extends downwardly relative to the first end portion and extends along an area of the body portion of the anti-spill chamber, with the fluid flowing above the uppermost section of the body portion after exiting via the outlet toward the overflow channel in a condition of overflow; and a reinforcement member disposed between the overflow channel and the area of the body portion of the anti-spill chamber. 2. The vehicle reservoir tank according to claim 1, wherein the inlet and the outlet of the anti-spill chamber are offset relative to each other. 3. The vehicle reservoir tank according to claim 1, wherein the inlet of the anti-spill chamber is disposed adjacent a first side of the body portion of the anti-spill chamber that is opposite to a second side of the body portion of the anti-spill chamber, which includes the area where the second end portion of the overflow channel is located. 4. The vehicle reservoir tank according to claim 1, wherein the inlet of the anti-spill chamber has an inlet longitudinal axis that intersects with an outlet longitudinal axis of the outlet of the anti-spill chamber to form an acute angle therebetween. 5. The vehicle reservoir tank according to claim 4, wherein the second end portion of the overflow channel has a longitudinal axis that intersects with the inlet longitudinal axis such that an intersection point therebetween is located on one side of the body portion of the anti-spill chamber. 6. The vehicle reservoir tank according to claim 5, wherein the inlet longitudinal axis and the outlet longitudinal axis intersect at an intersection point that is located on an opposite side of the body portion of the anti-spill chamber relative to the intersection point between the inlet longitudinal axis and the longitudinal axis of the second end portion of the overflow channel. 7. The vehicle reservoir tank according to claim 1, wherein the body portion of the anti-spill chamber has a larger transverse cross sectional area than the inlet and the outlet of the anti-spill chamber. 8. The vehicle reservoir tank according to claim 1, wherein the inlet of the anti-spill chamber includes an inlet connecting channel fluidly communicating the overflow port of the main reservoir chamber with the anti-spill chamber. 9. The vehicle reservoir tank according to claim 8, wherein the outlet of the anti-spill chamber includes an outlet connecting channel fluidly communicating the first end portion of the overflow channel to the anti-spill chamber, with the inlet and outlet connecting channels being offset relative to each other. 10. The vehicle reservoir tank according to claim 8, further comprising a first reinforcement member disposed between the inlet connecting channel and the overflow channel; and a second reinforcement member disposed along the inlet connecting channel on a side opposite to the first reinforcement member. 11. The vehicle reservoir tank according to claim 1, wherein the reinforcement member, the overflow channel and the anti-spill chamber are a one-piece unitary structure. 12. The vehicle reservoir tank according to claim 1, wherein the main reservoir chamber and the anti-spill chamber are a one-piece unitary structure. 13. The vehicle reservoir tank according to claim 1, wherein the second end portion of the overflow channel has an open end that is located downwardly relative to the overflow port of the main reservoir chamber. 14. The vehicle reservoir tank according to claim 1, wherein the anti-spill chamber includes a baffle arranged between the inlet and outlet to prevent fluid from flowing on a linear path between the inlet and outlet. 15. The vehicle reservoir tank according to claim 14, wherein the baffle is located in front of the outlet and is dimensioned to be equal to or greater than an opening of the outlet. 16. The vehicle reservoir tank according to claim 14, wherein the anti-spill chamber includes a lip located adjacent the outlet and extending towards the baffle to disturb fluid flow in the anti-spill chamber prior to entering the outlet. 17. The vehicle reservoir tank according to claim 1, wherein the anti-spill chamber includes a lip located adjacent the outlet and extending in a direction to disturb fluid flow in the anti-spill chamber prior to entering the outlet. 18. The vehicle reservoir tank according to claim 1, wherein the reinforcement member is contoured to direct fluid entering the body portion toward the overflow port. 19. The vehicle reservoir tank according to claim 1, wherein the reinforcement member divides the body portion from the overflow channel such that the body portion is in fluid communication with the overflow channel only through the outlet and the first end portion. 20. The vehicle reservoir tank according to claim 19, wherein the reinforcement member is positioned on a first side of the body portion, and the outlet is positioned on a second side of the body portion, the first side being opposite the second side. 21. The vehicle reservoir tank according to claim 1, wherein the anti-spill chamber is directly coupled to the main reservoir chamber. 22. The vehicle reservoir tank according to claim 21, wherein the overflow port of the main reservoir chamber is directly aligned with the inlet. 23. A vehicle reservoir tank comprising: a main reservoir chamber having a fluid drain port and an overflow port disposed at an upper portion of the main reservoir chamber; an anti-spill chamber having a body portion, an inlet at one end of the body portion and an outlet at another end of the body portion with the inlet being externally coupled to the overflow port of the main reservoir chamber, the anti-spill chamber being configured to restrict fluid flowing from the main reservoir chamber, the inlet of the anti-spill chamber having an inlet longitudinal axis that intersects with an outlet longitudinal axis of the outlet of the anti-spill chamber to form an acute angle therebetween; and an overflow channel having a first end portion fluidly coupled to the outlet of the anti-spill chamber, and an intermediate curved portion extending from the first end portion to a second end portion such that the second end portion of the overflow channel extends downwardly relative to the first end portion and extends along an area of the body portion of the anti-spill chamber. 24.
