Measured dosing and spray bottle for multi-use applications and associated method of using

A method of cleaning a grill, the grill having an upper grill and a lower grill, the method comprising:

• providing a bottle having:
• a dosing chamber with a first outlet, the dosing chamber including a volume defined between an upper end of the bottle, the first outlet, and a partition that includes a partition sidewall interfacing with the dosing chamber, the partition sidewall extending a length between one partition sidewall end at a lower end of the dosing chamber and an opposite partition sidewall end closer to the upper end of the bottle and terminating prior to the upper end of the bottle, the length of the partition sidewall extending along an axis at an angle in a direction from the lower end of the dosing chamber toward the upper end of the bottle such that the volume of the dosing chamber increases in the direction from the lower end of the dosing chamber toward the upper end of the bottle along the length of the partition sidewall, the axis along which the partition sidewall extends intersecting a second outlet, wherein the opposite partition sidewall end lies in terminates at a first plane that intersects the first outlet, and wherein the opposite partition sidewall end is aligned with the second outlet via a second axis extending through the second outlet and the opposite partition sidewall end;
• the second axis extending perpendicular to a second plane along which the upper end of the bottle extends;
• the first plane extending parallel to the second plane;
• a reservoir chamber with the second outlet, the reservoir chamber including a volume defined between the second outlet and the partition, the reservoir chamber configured for storing a solution;
• a sprayer for dispensing solution via the second outlet, the sprayer including a spray head and a trigger that when actuated draws solution from the reservoir chamber and dispenses it by spraying;
• filling the dosing chamber with a predetermined dose of solution from the reservoir chamber when the bottle is tilted at an angle from vertical so that solution flows from the reservoir chamber into the dosing chamber;
• dispensing the solution onto the lower grill by pouring the solution onto the lower grill from the first outlet;
• dispensing the solution onto the upper grill by spraying the solution onto the upper grill.
