1) A jar including:

• a body having an upper wall,
• a flexible pouch containing a product to be delivered,
• a deformable chamber delimited by a rigid wall and a flexible diaphragm, in fluidic communication with, on the one hand, the flexible pouch and, on the other hand, a dispensing orifice opening onto the upper wall,
• a lid having an exterior upper face visible from the outside and, opposite the exterior upper face, a lower face having substantially the same radius of curvature as the upper wall of the body, mounted on the upper wall to be mobile between an open position and a closed position such that the movement of the lid between the open position and the closed position consists in a sliding of the lid on the upper wall, this one having a flat or concave shape,
• pressurization means adapted to press on the flexible diaphragm during the movement of the lid from the closed position to the open position.
