Bottle with a roll-on applicator and a stopper

A bottle including a reservoir for a liquid or semi-fluid product and a dispensing head projecting from the reservoir along a main axis. The dispensing head includes a roll-on applicator including a ball holder in which a ball is caged and from which a cap of the ball emerges. The bottle includes a rotary stopper suitable for covering the roll-on applicator in a closed position of the bottle, and for being released from the roll-on applicator for distributing product in an open position of the bottle. The ball holder is mounted translatably along the main axis, the roll-on applicator including an elastic component inserted between an applicator body and the ball holder. The ball moves in translation jointly with the ball holder to take a retracted position when the roll-on applicator is covered by the rotary stopper and a deployed position when the rotary stopper is released from the roll-on applicator.
