The subject matter described herein includes a container having a substantially tubular body forming a first volume for receiving a first fluid. The body includes a first and a second end, and the first end includes a dispenser provided with an aperture making it possible to dispense the contents of the container. The second end includes a closure element having a flexible wall making it possible for the flexible wall to be displaced between a first and a second position relative to the dispenser in order to thus dispense the contents of the container. The container includes a capsule with an outer wall forming a second volume for containing a second fluid. The capsule is positioned between the dispenser and the flexible wall respectively. The capsule is suitable for releasing the second fluid into the first volume during or after a first displacement of the flexible wall from its first position towards its second position.
