An applicator and packaging device including a container forming a recess containing a measured quantity of product and delineating an opening capable of communicating with the recess. The container is integral with a porous applicator in an illustrated example. When the opening is closed by a cover strip, the applicator is at least partially disposed in the recess, and emerges at least partially through the opening when the container is in the open position. The cover strip is integral with a support of greater rigidity than that of the cover strip and extends at least partially around the opening.
