A case assembly, containing a cosmetic product, and a closure cap associated with that case by way of complementary attachment and release means, wherein the case as well as the attachment and release means for the cap are completely integrated into the cap; and those means are constituted by a hollow piston, movable in translation, disposed concentrically in a bore of the cap and capable of sliding therein, the hollow piston having a bore in which the case carrying the cosmetic product is housed and secured at one end by way of removable attachment means, the piston furthermore having a locking and unlocking mechanism interposed between said piston and the cap and movable in opposite directions by axial pressure exerted simultaneously on the cap and on a visible surface of a base of the integrated case, which base is in contact with the piston, so as to cause release, of said piston and the case, and enable said base of the case to extend from said cap to thereby be graspable by a user in order to remove said case.
