Your plastic water bottle may smell like chlorine because it has been exposed to chlorine-based cleaners or tap water treated with chlorine. Plastic can absorb odors, making the smell linger. To remove the odor, thoroughly wash the bottle with a mixture of baking soda and water, or use a solution of vinegar and water, then rinse it well. Letting it air-dry completely before the next use can also help eliminate any residual smells.
