A bottle gives a toy characterized by having a cylindrical container inside which, when changing the position of the bottle, a piston of heavier material provided with a sound device that imitates a child's crying moves; Said piston is drilled throughout its length so that the air coming from the upper part of the inner cylinder, once it has acted on the sound device, exits to the outside through holes made in the lower lid of the bottle, holes that also allow air to enter when the bottle is invert again to place it in its normal primitive position.
