The cup includes a deformable peripheral attachment zone configured to attach the cup to the container, a central opening configured to allow the passage of an outlet shaft of the product, and a bottom wall which surrounds the central opening and comprises a peripheral descending part and a central part. The central part includes a protective zone configured to limit deformation of the central part when the deformable attachment zone of the cup is deformed in order to attach the cup to the container.
