A packaging assembly for a cosmetic product has a receptacle which can contain the product, and an insert which supports a dispensing member and is removably mounted on the receptacle in order to allow, when it is mounted on the receptacle, product to be dispensed by the dispensing member. The insert is configured to cooperate with the receptacle so that, when the receptacle is moved to be mounted on and/or removed from the insert, the insert successively moves via a first position in which the force necessary for the movement reaches a first local maximum, and a second position in which the force reaches a second local maximum.
